From the desk of Editor

It is my great privilege and honour to have the opportunity to write the editorial of this issue of the NE Quest After a successful journey of 4 years of this forum while taking the pen to write for the news letter suddenly an Assamese poem has pop up to my mind Although these beautiful words are impossible to translate still if I try perhaps it may look like ldquoEvery droplets of water falling from the clouds fills the vast ocean the coagulation of smallest sand particles builds the mighty earthhelliprdquo As said in this poem our forum was also started only with two members on a golden moment of 13th November 2004 and by now in its 5th year of span we have strength of 263 members Hereby I would like to thank Arindam for conceiving and executing such a beautiful idea and giving us a glorious platform to share our thoughts I strongly believe that this forum will help us to develop our writing or expression ability and also to build constructive thoughts to help the progress of our region I wish a very bright future of our forum Today through this column of editorial I would like to take the opportunity to put forwards few of my bubble of feelings for your kind attention Firstly I would like to draw our attention towards the increasing terrorist activities in Indian particularly in our NE region Probably nobody will ever be able to forget the incident of 31 October 2008 even though presently living far away still when I got the news I felt myself deep and deep inside sea ndash everywhere I saw only bluehellip We really donrsquot know in which

direction our nation has been driven by these present situations Probably except terrorism activities our nation is lagging behind in all respect from rest of the world We canrsquot compete with the world why What we donrsquot have - resource manpower or knowledge I think actually we have everything For instance if we compare the available natural resources only of NE Region probably we will be in a very good rank in the world Just for statistical data if I compare one of the states of north east India Assam with Israel which is considered as one of the most advance countries in south west Asia then we will find Israel has total area of 2077022072 km2 total population just above 7337000 and Assam stands with 78438 km2 of land having approximate 26656528 population Most interesting data is the population density ie 324km2 and 340km2 for Israel and Assam respective really very close figure On the other hand Israel is a nation with very limited natural resources even dry and with limited water resources in contrast Assam has everything in plenty But where is Israel and where is Assam Why so I know that there are many factors but at this moment I think terrorism and its related happenings are the biggest curse for the people of Assam as well as for the nation One day there will be a bomb blast and from the next day different parties (either political or non-political) will start to call ldquoASSAM BANDHrdquo to protest it Is there any positive out put from the ldquoBandhrdquo culture I think no the only impact is that we are directly going down in path of progress by one day from the rest of the world So the ldquoBandhrdquo is becoming a prime detrimental factor in progress of the state and it is giving just political advantage to some groups or people Even probably calling a ldquoBandhrdquo is also against our constitution as it affects the ldquoindividual freedomrdquo so it is against the law and should be consider as a crime This black snack ldquoBandhrdquo is squizzing us from all direction Therefore I request everybody to think something to make aware the common people of our region about this silent killer I strongly believe that general awareness is

Finally I would like to say my personal thanks to Dr Arindam Adhikari for his help in every step and gratefully acknowledge members of the editorial board for their suggestions I thank all the contributors for their articles and my special thanks goes to Mr Anirban Adhikari for his effort in making the magnificent work for the cover page At the last I pray to God to bring peace and progress to our region

the only solution to fight against such an enemy otherwise very soon it is going destroy us As a detrimental factor of progress I want to point out another fact ldquoThe honestyrdquo I am sure that many of us will not be agree with this but if anyone think from hisher soul heshe will agree that either willingly or unwillingly most of us doing very dishonest works may be some time for personal benefit or may be due to survive in a particular situation or may be sometime under pressure Now we are in a situation that dishonesty (corruption) is in our gene so we donrsquot think some dishonest work as to be dishonest From a service man to a daily wage labour from a politician to common people dishonesty has touched everybody in different form As an example let us consider a daily wage man and you employed him to work at your home but if you donrsquot observe him he definitely will not do his duty properly so that is also a kind of dishonesty Therefore to climb the ladder of progress we have to bring back our honesty Somehow we have to show the common people that how dishonesty is pulling us from our back and we are walking years after years but still in the same place If we become honest to some extent then at least we will be able to use the funds for various works properly and there will be progress

Therefore in my opinion to overcome all these factors public awareness and motivation of common people towards the right path of progress is the only solution So hereby I would like to through a query towards our honourable members that - is there anything that we can do which will have a direct physical impact to awake the people of our region from their deep sleep and also to make aware of power and extreme strength that the common people have with them

If somehow this can be done then we will see that politician or the group of people who nowadays most of the time seeks only individual benefits will not be able to motivate them rather general people will be motivating them and the nation will start to climb the ladder of progress

7 New activity

To run the forum smoothly to make it more organised and to speed up activities formation of a committeeteam is essential

The combined discussion of the moderators and senior members make the forum feel the importance of Advisors co-ordinator volunteer webmasters etc Of course it needs more discussion and will be approved by poll

8 Guidelines for the forum The moderators formulated some guidelines for the forum which are as follow These guidelines were kept open for discussion in the forum With time and need the guidelines will be changed

i Anybody in the forum can start a meaningful and constructive discussion after discussion with moderators

ii Comments from the individual members do not necessarily reflect the view of the forum

iii No single moderator can take a crucial decision All decision would be taken by the moderators unanimously or together with the group as majority

iv One should not write any massage to the forum addressing some particular members It should always start with Dear all Dear esteemed members etc

v If one has to write a mail to a particular member shehe should write personal mail

vi Everyone has the freedom to speak but that doesnrsquot mean that one should attack personally Of course we do have differences There can be debate or discussion but it should always be a healthy one Onersquos personal comment should be written in such a way that it reflects hisher view only It should not touch others sentimentsemotions

vii Whenever we are in a forum society home members should be sensitive caring enough to their comments so that it does not hurt sentiment of any second members

viii Members should not post greetings messages (Bihu wish New Year wish etc) to the forum

ix Members should post authentic news only The source of the news should be authentic No controversial news or comment should be posted to the forum

x Our main aim is to discuss science to generate science consciousness scientific temperament sensitivity awareness and research for the benefit of the mankind in general and North East India in particular

xi In severe cases moderators can take a hard decision unanimously or majority wise ( may be through poll) (This point needs to be accepted by all the members)

While sending request or while fulfilling request for articles please follow the following points

bull The forum has been formed to help each other When a member requests articlesliterature to forum members of the forum are always happy to help the person by supplying the articles But at

N E Quest Volume 2 Issue 4 January 2009 7

Newsletter of North East India Research Forum

this stage we have to keep in mind that the article should be sent to the person who requested it not to the whole forum as it creates lots of unnecessary mails in the message box of the forum Moreover if it continues it become a irritation also for many members

bull It is also the duty of the person who requests article to acknowledge the person who helped himher This can be done by writing Request fulfilled by in the subject area while composing the mail and write a thanking message in the main message board Once this is done then if some other members want to send the article will know about the status of the request This will also help members in keeping mailbox clean

bull Before asking for article heshe should always check hisher instituteuniversity libraries (online resources) If it is not available or accessible then only the member should request to the forum

bull Moreover sending articles (copyright protected articles) to the open forum violates copyright act So please send the article to the person who requests not to everybody through this open forum

News from Mars Scientists have announced the discovery of substantial deposits of carbonate rocks on Mars Although the new rocks are not from the bed of a long-lost ocean as would once have been hoped the discovery is still fanning hopes that the rocks might hold preserved traces of organic matter from the

planets early history The carbonates were discovered using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) an instrument carried on NASAs Mars Reconnaissance Orbiter (MRO) CRISM results show evidence of magnesium carbonate (magnesite) in an area known as Nili Fossae that sits on the edge of Isidis Planitia one of the planets great impact basins (for details Ehlmann B L et al Science 322 2008 1828)

More than four years after researchers first said they had found methane gas on Mars a scientist claims that he has nailed the controversial detection

and identified key sources of the gas On Earth methane is mostly biological in origin on Mars it could signal microbes living deep underground The latest work suggests that martian methane is concentrated in both space and time mdash at a handful of hotspots hundreds of kilometres across plumes of methane bloom and dissipate in less than a year Scientist Michael Mumma a spectroscopy expert obtained data from telescopes in Hawaii and Chile that supported the notion of methane hotspots According to the scientist he has confirmed the presence of methane by matching four lines in his infrared spectra of the planets atmosphere to the characteristic signature of methane mdash a more definite determination than previous analyses mdash and

found more evidence that the methane is localized in discrete hotspots which peak at levels of 60 parts per billion The more important observations is the short lifetimes of the plumes Previously methane was thought to be destroyed in the atmosphere by sunlight mdash a slow process that allows the gas to mix in the atmosphere and persist for about 300 years A global level of 10 parts per billion and a lifetime of hundreds of years means that a few hundred tonnes of methane are entering the atmosphere each year the work of a few thousand cows But plumes of 60 parts per billion that live for less than a year imply a methane-production rate several orders of magnitude higher This is a big deal says Sushil Atreya of the University of Michigan in Ann Arbor a co-author of the 2004 Mars Express paper At the moment whether the methane plumes are biological or geological in origin is impossible to know at the moment But NASAs next Mars rover will be able to analyse at levels of parts per trillion the fractional concentrations of the carbon isotopes in each methane molecule Life on Earth prefers to process lighter carbon-12 atoms And so on Mars methane freighted with carbon-12 could be a sign of a biological

Successful test of GSLV

On 20th December 2008 Indian Space Research Organization (ISRO) has successfully conducted a test of its indigenous cryogenic (supercooled fuel) engine to be used in the next geosynchronous launch vehicle (GSLV-D3) launch in April 2009 for carrying the 23-tonne geo-stationary experimental satellite (GSAT) mission Typically hydrogen and oxygen are used which need to be held respectively below -253 degrees Celsius and -183 degrees Celsius to remain in liquid form The cryogenic engine develops a thrust of 73 kilo Newtons (kN) in vacuum with a specific impulse of 454 seconds (756 minutes) and can carry 22 tonnes Working on a staged combustion cycle with an integrated turbo-pump the engine will have 42000 rotations per minute (rpm) It also has two steering engines developing a thrust of 2 kN each to enable three-axis control of the launch vehicle during the flight mission According to the statement of ISRO The hot test was carried out for 200 seconds (333 minutes) during which the engine was operated in the nominal and 13 percent up-rated thrust regimes All the propulsion parameters were satisfactory and matched with predictions Cryogenic engine technology is currently present only in Russia and the US The semi-cryogenic engines will facilitate applications for future space missions like the reusable launch vehicle the unified launch vehicle and the vehicle for inter-planetary missions Chidambaram added The central government has already approved the development of semi-cryogenic engines for space transportation at a cost of Rs1798 crore (approx Rs18 billion) with a foreign exchange component of Rs588 crore (Rs588 billion)

Enzyme that degrade fat Researchers at the University of California Berkeley under the supervision of Prof Hei Sook Sul identified a new enzyme that plays a far more important role than expected in controlling the breakdown of fat The new enzyme within fat cells that is a key regulator of fat metabolism and body weight making it a promising target in the search for a treatment for human obesity In a new study to be published Jan 11 in the journal Nature Medicine researchers report that mice that have had this enzyme disabled remained lean despite eating a high-fat diet and losing a hormone that suppresses appetite The enzyme in the spotlight adipose-specific phospholipase A2 (AdPLA) is found in abundance only in fat tissue AdPLA sets off a chain of events that increases levels of a signalling molecule called prostaglandin E2 (PGE2) which suppresses the breakdown of fat Mice that have no AdPLA have lower PGE2 levels and a higher rate of fat metabolism

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

First Gene Discovered For Most Common Form of Epilepsy

An international team of researchers led by investigators at Columbia University Medical Center has uncovered the first gene linked to the most common

type of epilepsy called Rolandic epilepsy The finding is the first step in unlocking the causes of common childhood epilepsies (a common chronic neurological disorder characterized by recurrent unprovoked seizures) and developing more effective treatments Children with Rolandic and other types of epilepsies are usually treated with drugs that prevent seizures by suppressing electrical activity in the entire brain Pediatric neurologist Deb Pal MD PhD Columbia University research scientist in the Department of Psychiatry at the College of Physicians amp Surgeons said Most epilepsies have a genetic influence much of which has yet to be discovered If we knew the actual genetic causes then we could try to stop or reverse the processes that lead to seizures and other neurological impairments This finding will hopefully help lead us to the right intervention The findings also offer possible insights into the causes of attention deficit hyperactivity disorder (ADHD) speech dyspraxia (a speech disorder in which a person has a delay in speech development due to motor coordination difficulties) and developmental coordination disorder (DCD) Findings will be published in an advance online issue of the European Journal of Human Genetics on January 28 2009 (Sourcewwwsciencedailycom)

MS Swaminathan father of Indiarsquos green revolution put forwarded the concept for the region to adopt to preserve its rich bio-

diversity in his lecture on the second day of the National Science Congress on the North Eastern Hill University (Nehu) campus According to Swaminathan ldquoEvergreen revolution would mean the need to carry out organic agriculture maintaining the ecology of the Northeastrdquo explaining that every species of flora was precious and needed care ldquoThe Northeast is one of the 12 mega-bio diversity areas of the country and this itself indicates the urgency of tapping the regionrsquos potential by the indigenous communitiesrdquo He also called for tapping floriculture in the Northeast as the orchids and other flowers are

in high demand in India and abroad He said orchids are believed to have evolved in the region ldquoOf the 1300 species belonging to 158 genera reported from India the Northeast has the highest concentration with nearly 700 species of orchidsrdquo Attention should be given to conserve many vanishing species like the 34 species of orchids from the region that are listed among are should be in much priority He also mentioned the ldquosacred grovesrdquo of Meghalaya mdash the community-preserved trees mdash and said this concept of local conservation tradition

Seco

or microbes are secondary

Need

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Spices plant has also tremendous demand in the state as well as in whole country A few spices species cultivated by the tribal people are Allium turberosum Amomum aromaitcum Amomum subulatum Curcuma amada Curcuma Zedoaria Piper longum Piper peepuloides Piper mullesua etc

Timber yielding plants The economy of the state depends upon

the timber plant of the state The timber of this state had great demand throughout the country The bamboo canes also play an important role in the economy of the people of the state A few important timber yielding plant are Actinodaphne obovata Albizia lucida Alostonia schlaris Artocarpus lacucha Biscofia javanica Bombax ceiba Cinnamommum glaucescens Dipterocarpus retusus Gynocardia odorata Kydia calycina Pinus roxburghii Quercus griffithii etc A few common bamboo species are Bambusa pallida Bambusa tulda Dendrocalamus hamiltoni Dendrocalamus strictus Melocanna baccifera etc Another a few cane species are Calamus flagellum Calamus floribundus Calamus latifolius etc

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

An Efficient Method for the Synthesis of Indolo[32-b]carbazoles from 33prime-bis(indolyl)methanes Catalysed by Molecular Iodine

In this reaction strategy utilizing 33prime-bis(indolyl)methanes 1 with catalytic amount of molecular iodine in refluxing acetonitrile for 20-35 minutes afforded after work-up indolo[32-b]carbazoles 2 in good yields Although the yield of products in the reaction is not very high in some cases there is selective formation of the indolo[32-b]carbazole

From the desk of Editor

It is my great privilege and honour to have the opportunity to write the editorial of this issue of the NE Quest After a successful journey of 4 years of this forum while taking the pen to write for the news letter suddenly an Assamese poem has pop up to my mind Although these beautiful words are impossible to translate still if I try perhaps it may look like ldquoEvery droplets of water falling from the clouds fills the vast ocean the coagulation of smallest sand particles builds the mighty earthhelliprdquo As said in this poem our forum was also started only with two members on a golden moment of 13th November 2004 and by now in its 5th year of span we have strength of 263 members Hereby I would like to thank Arindam for conceiving and executing such a beautiful idea and giving us a glorious platform to share our thoughts I strongly believe that this forum will help us to develop our writing or expression ability and also to build constructive thoughts to help the progress of our region I wish a very bright future of our forum Today through this column of editorial I would like to take the opportunity to put forwards few of my bubble of feelings for your kind attention Firstly I would like to draw our attention towards the increasing terrorist activities in Indian particularly in our NE region Probably nobody will ever be able to forget the incident of 31 October 2008 even though presently living far away still when I got the news I felt myself deep and deep inside sea ndash everywhere I saw only bluehellip We really donrsquot know in which

direction our nation has been driven by these present situations Probably except terrorism activities our nation is lagging behind in all respect from rest of the world We canrsquot compete with the world why What we donrsquot have - resource manpower or knowledge I think actually we have everything For instance if we compare the available natural resources only of NE Region probably we will be in a very good rank in the world Just for statistical data if I compare one of the states of north east India Assam with Israel which is considered as one of the most advance countries in south west Asia then we will find Israel has total area of 2077022072 km2 total population just above 7337000 and Assam stands with 78438 km2 of land having approximate 26656528 population Most interesting data is the population density ie 324km2 and 340km2 for Israel and Assam respective really very close figure On the other hand Israel is a nation with very limited natural resources even dry and with limited water resources in contrast Assam has everything in plenty But where is Israel and where is Assam Why so I know that there are many factors but at this moment I think terrorism and its related happenings are the biggest curse for the people of Assam as well as for the nation One day there will be a bomb blast and from the next day different parties (either political or non-political) will start to call ldquoASSAM BANDHrdquo to protest it Is there any positive out put from the ldquoBandhrdquo culture I think no the only impact is that we are directly going down in path of progress by one day from the rest of the world So the ldquoBandhrdquo is becoming a prime detrimental factor in progress of the state and it is giving just political advantage to some groups or people Even probably calling a ldquoBandhrdquo is also against our constitution as it affects the ldquoindividual freedomrdquo so it is against the law and should be consider as a crime This black snack ldquoBandhrdquo is squizzing us from all direction Therefore I request everybody to think something to make aware the common people of our region about this silent killer I strongly believe that general awareness is

Finally I would like to say my personal thanks to Dr Arindam Adhikari for his help in every step and gratefully acknowledge members of the editorial board for their suggestions I thank all the contributors for their articles and my special thanks goes to Mr Anirban Adhikari for his effort in making the magnificent work for the cover page At the last I pray to God to bring peace and progress to our region

the only solution to fight against such an enemy otherwise very soon it is going destroy us As a detrimental factor of progress I want to point out another fact ldquoThe honestyrdquo I am sure that many of us will not be agree with this but if anyone think from hisher soul heshe will agree that either willingly or unwillingly most of us doing very dishonest works may be some time for personal benefit or may be due to survive in a particular situation or may be sometime under pressure Now we are in a situation that dishonesty (corruption) is in our gene so we donrsquot think some dishonest work as to be dishonest From a service man to a daily wage labour from a politician to common people dishonesty has touched everybody in different form As an example let us consider a daily wage man and you employed him to work at your home but if you donrsquot observe him he definitely will not do his duty properly so that is also a kind of dishonesty Therefore to climb the ladder of progress we have to bring back our honesty Somehow we have to show the common people that how dishonesty is pulling us from our back and we are walking years after years but still in the same place If we become honest to some extent then at least we will be able to use the funds for various works properly and there will be progress

-Manab Sharma

An oldest printing press

Therefore in my opinion to overcome all these factors public awareness and motivation of common people towards the right path of progress is the only solution So hereby I would like to through a query towards our honourable members that - is there anything that we can do which will have a direct physical impact to awake the people of our region from their deep sleep and also to make aware of power and extreme strength that the common people have with them

If somehow this can be done then we will see that politician or the group of people who nowadays most of the time seeks only individual benefits will not be able to motivate them rather general people will be motivating them and the nation will start to climb the ladder of progress

7 New activity

To run the forum smoothly to make it more organised and to speed up activities formation of a committeeteam is essential

The combined discussion of the moderators and senior members make the forum feel the importance of Advisors co-ordinator volunteer webmasters etc Of course it needs more discussion and will be approved by poll

8 Guidelines for the forum The moderators formulated some guidelines for the forum which are as follow These guidelines were kept open for discussion in the forum With time and need the guidelines will be changed

i Anybody in the forum can start a meaningful and constructive discussion after discussion with moderators

ii Comments from the individual members do not necessarily reflect the view of the forum

iii No single moderator can take a crucial decision All decision would be taken by the moderators unanimously or together with the group as majority

iv One should not write any massage to the forum addressing some particular members It should always start with Dear all Dear esteemed members etc

v If one has to write a mail to a particular member shehe should write personal mail

vi Everyone has the freedom to speak but that doesnrsquot mean that one should attack personally Of course we do have differences There can be debate or discussion but it should always be a healthy one Onersquos personal comment should be written in such a way that it reflects hisher view only It should not touch others sentimentsemotions

vii Whenever we are in a forum society home members should be sensitive caring enough to their comments so that it does not hurt sentiment of any second members

viii Members should not post greetings messages (Bihu wish New Year wish etc) to the forum

ix Members should post authentic news only The source of the news should be authentic No controversial news or comment should be posted to the forum

x Our main aim is to discuss science to generate science consciousness scientific temperament sensitivity awareness and research for the benefit of the mankind in general and North East India in particular

xi In severe cases moderators can take a hard decision unanimously or majority wise ( may be through poll) (This point needs to be accepted by all the members)

While sending request or while fulfilling request for articles please follow the following points

bull The forum has been formed to help each other When a member requests articlesliterature to forum members of the forum are always happy to help the person by supplying the articles But at

N E Quest Volume 2 Issue 4 January 2009 7

Newsletter of North East India Research Forum

this stage we have to keep in mind that the article should be sent to the person who requested it not to the whole forum as it creates lots of unnecessary mails in the message box of the forum Moreover if it continues it become a irritation also for many members

bull It is also the duty of the person who requests article to acknowledge the person who helped himher This can be done by writing Request fulfilled by in the subject area while composing the mail and write a thanking message in the main message board Once this is done then if some other members want to send the article will know about the status of the request This will also help members in keeping mailbox clean

bull Before asking for article heshe should always check hisher instituteuniversity libraries (online resources) If it is not available or accessible then only the member should request to the forum

bull Moreover sending articles (copyright protected articles) to the open forum violates copyright act So please send the article to the person who requests not to everybody through this open forum

News from Mars Scientists have announced the discovery of substantial deposits of carbonate rocks on Mars Although the new rocks are not from the bed of a long-lost ocean as would once have been hoped the discovery is still fanning hopes that the rocks might hold preserved traces of organic matter from the

planets early history The carbonates were discovered using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) an instrument carried on NASAs Mars Reconnaissance Orbiter (MRO) CRISM results show evidence of magnesium carbonate (magnesite) in an area known as Nili Fossae that sits on the edge of Isidis Planitia one of the planets great impact basins (for details Ehlmann B L et al Science 322 2008 1828)

More than four years after researchers first said they had found methane gas on Mars a scientist claims that he has nailed the controversial detection

and identified key sources of the gas On Earth methane is mostly biological in origin on Mars it could signal microbes living deep underground The latest work suggests that martian methane is concentrated in both space and time mdash at a handful of hotspots hundreds of kilometres across plumes of methane bloom and dissipate in less than a year Scientist Michael Mumma a spectroscopy expert obtained data from telescopes in Hawaii and Chile that supported the notion of methane hotspots According to the scientist he has confirmed the presence of methane by matching four lines in his infrared spectra of the planets atmosphere to the characteristic signature of methane mdash a more definite determination than previous analyses mdash and

found more evidence that the methane is localized in discrete hotspots which peak at levels of 60 parts per billion The more important observations is the short lifetimes of the plumes Previously methane was thought to be destroyed in the atmosphere by sunlight mdash a slow process that allows the gas to mix in the atmosphere and persist for about 300 years A global level of 10 parts per billion and a lifetime of hundreds of years means that a few hundred tonnes of methane are entering the atmosphere each year the work of a few thousand cows But plumes of 60 parts per billion that live for less than a year imply a methane-production rate several orders of magnitude higher This is a big deal says Sushil Atreya of the University of Michigan in Ann Arbor a co-author of the 2004 Mars Express paper At the moment whether the methane plumes are biological or geological in origin is impossible to know at the moment But NASAs next Mars rover will be able to analyse at levels of parts per trillion the fractional concentrations of the carbon isotopes in each methane molecule Life on Earth prefers to process lighter carbon-12 atoms And so on Mars methane freighted with carbon-12 could be a sign of a biological

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Seco

or microbes are secondary

Need

for use in medicine agriculture industry and

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

POEM It is our proud privilege to congratulate Mr Kamal Kumar Tanti for receiving the ldquoMunin Borkotoki Literary Awardrdquo for his poetry book Maarangburu Amar Pita and I am taking the opportunity to publish one of his award wining poem ldquoBhraman Kahinirdquo

Probably an exact translation of words that come out spontaneously form the heart of a poet is impossible still a creditable effort was taken by Geetika Phukan to translated it to English) Travelogue On the silent street in Salonah tea garden We lost our way Grieving at our grief An old Kachari said ldquoChildren follow your noses There are dreams on the way not reality At the end of the dreams there will be dawnrdquo We realized Looking for flowers is easier Than finding thorns Flowers do not make us feel They feel themselves Thorns do not feel their sharpness They make others feel As travelers We wanted to thank the Old Kachari So halfway through we killed him And left his blood for the vultures and crows The cuckoos loved us for that And finally we reached a land of swords

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

compound

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

From the desk of Editor

It is my great privilege and honour to have the opportunity to write the editorial of this issue of the NE Quest After a successful journey of 4 years of this forum while taking the pen to write for the news letter suddenly an Assamese poem has pop up to my mind Although these beautiful words are impossible to translate still if I try perhaps it may look like ldquoEvery droplets of water falling from the clouds fills the vast ocean the coagulation of smallest sand particles builds the mighty earthhelliprdquo As said in this poem our forum was also started only with two members on a golden moment of 13th November 2004 and by now in its 5th year of span we have strength of 263 members Hereby I would like to thank Arindam for conceiving and executing such a beautiful idea and giving us a glorious platform to share our thoughts I strongly believe that this forum will help us to develop our writing or expression ability and also to build constructive thoughts to help the progress of our region I wish a very bright future of our forum Today through this column of editorial I would like to take the opportunity to put forwards few of my bubble of feelings for your kind attention Firstly I would like to draw our attention towards the increasing terrorist activities in Indian particularly in our NE region Probably nobody will ever be able to forget the incident of 31 October 2008 even though presently living far away still when I got the news I felt myself deep and deep inside sea ndash everywhere I saw only bluehellip We really donrsquot know in which

direction our nation has been driven by these present situations Probably except terrorism activities our nation is lagging behind in all respect from rest of the world We canrsquot compete with the world why What we donrsquot have - resource manpower or knowledge I think actually we have everything For instance if we compare the available natural resources only of NE Region probably we will be in a very good rank in the world Just for statistical data if I compare one of the states of north east India Assam with Israel which is considered as one of the most advance countries in south west Asia then we will find Israel has total area of 2077022072 km2 total population just above 7337000 and Assam stands with 78438 km2 of land having approximate 26656528 population Most interesting data is the population density ie 324km2 and 340km2 for Israel and Assam respective really very close figure On the other hand Israel is a nation with very limited natural resources even dry and with limited water resources in contrast Assam has everything in plenty But where is Israel and where is Assam Why so I know that there are many factors but at this moment I think terrorism and its related happenings are the biggest curse for the people of Assam as well as for the nation One day there will be a bomb blast and from the next day different parties (either political or non-political) will start to call ldquoASSAM BANDHrdquo to protest it Is there any positive out put from the ldquoBandhrdquo culture I think no the only impact is that we are directly going down in path of progress by one day from the rest of the world So the ldquoBandhrdquo is becoming a prime detrimental factor in progress of the state and it is giving just political advantage to some groups or people Even probably calling a ldquoBandhrdquo is also against our constitution as it affects the ldquoindividual freedomrdquo so it is against the law and should be consider as a crime This black snack ldquoBandhrdquo is squizzing us from all direction Therefore I request everybody to think something to make aware the common people of our region about this silent killer I strongly believe that general awareness is

Finally I would like to say my personal thanks to Dr Arindam Adhikari for his help in every step and gratefully acknowledge members of the editorial board for their suggestions I thank all the contributors for their articles and my special thanks goes to Mr Anirban Adhikari for his effort in making the magnificent work for the cover page At the last I pray to God to bring peace and progress to our region

the only solution to fight against such an enemy otherwise very soon it is going destroy us As a detrimental factor of progress I want to point out another fact ldquoThe honestyrdquo I am sure that many of us will not be agree with this but if anyone think from hisher soul heshe will agree that either willingly or unwillingly most of us doing very dishonest works may be some time for personal benefit or may be due to survive in a particular situation or may be sometime under pressure Now we are in a situation that dishonesty (corruption) is in our gene so we donrsquot think some dishonest work as to be dishonest From a service man to a daily wage labour from a politician to common people dishonesty has touched everybody in different form As an example let us consider a daily wage man and you employed him to work at your home but if you donrsquot observe him he definitely will not do his duty properly so that is also a kind of dishonesty Therefore to climb the ladder of progress we have to bring back our honesty Somehow we have to show the common people that how dishonesty is pulling us from our back and we are walking years after years but still in the same place If we become honest to some extent then at least we will be able to use the funds for various works properly and there will be progress

Therefore in my opinion to overcome all these factors public awareness and motivation of common people towards the right path of progress is the only solution So hereby I would like to through a query towards our honourable members that - is there anything that we can do which will have a direct physical impact to awake the people of our region from their deep sleep and also to make aware of power and extreme strength that the common people have with them

If somehow this can be done then we will see that politician or the group of people who nowadays most of the time seeks only individual benefits will not be able to motivate them rather general people will be motivating them and the nation will start to climb the ladder of progress

7 New activity

To run the forum smoothly to make it more organised and to speed up activities formation of a committeeteam is essential

The combined discussion of the moderators and senior members make the forum feel the importance of Advisors co-ordinator volunteer webmasters etc Of course it needs more discussion and will be approved by poll

8 Guidelines for the forum The moderators formulated some guidelines for the forum which are as follow These guidelines were kept open for discussion in the forum With time and need the guidelines will be changed

i Anybody in the forum can start a meaningful and constructive discussion after discussion with moderators

ii Comments from the individual members do not necessarily reflect the view of the forum

iii No single moderator can take a crucial decision All decision would be taken by the moderators unanimously or together with the group as majority

iv One should not write any massage to the forum addressing some particular members It should always start with Dear all Dear esteemed members etc

v If one has to write a mail to a particular member shehe should write personal mail

vi Everyone has the freedom to speak but that doesnrsquot mean that one should attack personally Of course we do have differences There can be debate or discussion but it should always be a healthy one Onersquos personal comment should be written in such a way that it reflects hisher view only It should not touch others sentimentsemotions

vii Whenever we are in a forum society home members should be sensitive caring enough to their comments so that it does not hurt sentiment of any second members

viii Members should not post greetings messages (Bihu wish New Year wish etc) to the forum

ix Members should post authentic news only The source of the news should be authentic No controversial news or comment should be posted to the forum

x Our main aim is to discuss science to generate science consciousness scientific temperament sensitivity awareness and research for the benefit of the mankind in general and North East India in particular

xi In severe cases moderators can take a hard decision unanimously or majority wise ( may be through poll) (This point needs to be accepted by all the members)

While sending request or while fulfilling request for articles please follow the following points

bull The forum has been formed to help each other When a member requests articlesliterature to forum members of the forum are always happy to help the person by supplying the articles But at

N E Quest Volume 2 Issue 4 January 2009 7

Newsletter of North East India Research Forum

this stage we have to keep in mind that the article should be sent to the person who requested it not to the whole forum as it creates lots of unnecessary mails in the message box of the forum Moreover if it continues it become a irritation also for many members

bull It is also the duty of the person who requests article to acknowledge the person who helped himher This can be done by writing Request fulfilled by in the subject area while composing the mail and write a thanking message in the main message board Once this is done then if some other members want to send the article will know about the status of the request This will also help members in keeping mailbox clean

bull Before asking for article heshe should always check hisher instituteuniversity libraries (online resources) If it is not available or accessible then only the member should request to the forum

bull Moreover sending articles (copyright protected articles) to the open forum violates copyright act So please send the article to the person who requests not to everybody through this open forum

News from Mars Scientists have announced the discovery of substantial deposits of carbonate rocks on Mars Although the new rocks are not from the bed of a long-lost ocean as would once have been hoped the discovery is still fanning hopes that the rocks might hold preserved traces of organic matter from the

planets early history The carbonates were discovered using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) an instrument carried on NASAs Mars Reconnaissance Orbiter (MRO) CRISM results show evidence of magnesium carbonate (magnesite) in an area known as Nili Fossae that sits on the edge of Isidis Planitia one of the planets great impact basins (for details Ehlmann B L et al Science 322 2008 1828)

More than four years after researchers first said they had found methane gas on Mars a scientist claims that he has nailed the controversial detection

and identified key sources of the gas On Earth methane is mostly biological in origin on Mars it could signal microbes living deep underground The latest work suggests that martian methane is concentrated in both space and time mdash at a handful of hotspots hundreds of kilometres across plumes of methane bloom and dissipate in less than a year Scientist Michael Mumma a spectroscopy expert obtained data from telescopes in Hawaii and Chile that supported the notion of methane hotspots According to the scientist he has confirmed the presence of methane by matching four lines in his infrared spectra of the planets atmosphere to the characteristic signature of methane mdash a more definite determination than previous analyses mdash and

found more evidence that the methane is localized in discrete hotspots which peak at levels of 60 parts per billion The more important observations is the short lifetimes of the plumes Previously methane was thought to be destroyed in the atmosphere by sunlight mdash a slow process that allows the gas to mix in the atmosphere and persist for about 300 years A global level of 10 parts per billion and a lifetime of hundreds of years means that a few hundred tonnes of methane are entering the atmosphere each year the work of a few thousand cows But plumes of 60 parts per billion that live for less than a year imply a methane-production rate several orders of magnitude higher This is a big deal says Sushil Atreya of the University of Michigan in Ann Arbor a co-author of the 2004 Mars Express paper At the moment whether the methane plumes are biological or geological in origin is impossible to know at the moment But NASAs next Mars rover will be able to analyse at levels of parts per trillion the fractional concentrations of the carbon isotopes in each methane molecule Life on Earth prefers to process lighter carbon-12 atoms And so on Mars methane freighted with carbon-12 could be a sign of a biological

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

First Gene Discovered For Most Common Form of Epilepsy

An international team of researchers led by investigators at Columbia University Medical Center has uncovered the first gene linked to the most common

type of epilepsy called Rolandic epilepsy The finding is the first step in unlocking the causes of common childhood epilepsies (a common chronic neurological disorder characterized by recurrent unprovoked seizures) and developing more effective treatments Children with Rolandic and other types of epilepsies are usually treated with drugs that prevent seizures by suppressing electrical activity in the entire brain Pediatric neurologist Deb Pal MD PhD Columbia University research scientist in the Department of Psychiatry at the College of Physicians amp Surgeons said Most epilepsies have a genetic influence much of which has yet to be discovered If we knew the actual genetic causes then we could try to stop or reverse the processes that lead to seizures and other neurological impairments This finding will hopefully help lead us to the right intervention The findings also offer possible insights into the causes of attention deficit hyperactivity disorder (ADHD) speech dyspraxia (a speech disorder in which a person has a delay in speech development due to motor coordination difficulties) and developmental coordination disorder (DCD) Findings will be published in an advance online issue of the European Journal of Human Genetics on January 28 2009 (Sourcewwwsciencedailycom)

MS Swaminathan father of Indiarsquos green revolution put forwarded the concept for the region to adopt to preserve its rich bio-

diversity in his lecture on the second day of the National Science Congress on the North Eastern Hill University (Nehu) campus According to Swaminathan ldquoEvergreen revolution would mean the need to carry out organic agriculture maintaining the ecology of the Northeastrdquo explaining that every species of flora was precious and needed care ldquoThe Northeast is one of the 12 mega-bio diversity areas of the country and this itself indicates the urgency of tapping the regionrsquos potential by the indigenous communitiesrdquo He also called for tapping floriculture in the Northeast as the orchids and other flowers are

in high demand in India and abroad He said orchids are believed to have evolved in the region ldquoOf the 1300 species belonging to 158 genera reported from India the Northeast has the highest concentration with nearly 700 species of orchidsrdquo Attention should be given to conserve many vanishing species like the 34 species of orchids from the region that are listed among are should be in much priority He also mentioned the ldquosacred grovesrdquo of Meghalaya mdash the community-preserved trees mdash and said this concept of local conservation tradition

Seco

or microbes are secondary

Need

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Spices plant has also tremendous demand in the state as well as in whole country A few spices species cultivated by the tribal people are Allium turberosum Amomum aromaitcum Amomum subulatum Curcuma amada Curcuma Zedoaria Piper longum Piper peepuloides Piper mullesua etc

Timber yielding plants The economy of the state depends upon

the timber plant of the state The timber of this state had great demand throughout the country The bamboo canes also play an important role in the economy of the people of the state A few important timber yielding plant are Actinodaphne obovata Albizia lucida Alostonia schlaris Artocarpus lacucha Biscofia javanica Bombax ceiba Cinnamommum glaucescens Dipterocarpus retusus Gynocardia odorata Kydia calycina Pinus roxburghii Quercus griffithii etc A few common bamboo species are Bambusa pallida Bambusa tulda Dendrocalamus hamiltoni Dendrocalamus strictus Melocanna baccifera etc Another a few cane species are Calamus flagellum Calamus floribundus Calamus latifolius etc

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Finally I would like to say my personal thanks to Dr Arindam Adhikari for his help in every step and gratefully acknowledge members of the editorial board for their suggestions I thank all the contributors for their articles and my special thanks goes to Mr Anirban Adhikari for his effort in making the magnificent work for the cover page At the last I pray to God to bring peace and progress to our region

the only solution to fight against such an enemy otherwise very soon it is going destroy us As a detrimental factor of progress I want to point out another fact ldquoThe honestyrdquo I am sure that many of us will not be agree with this but if anyone think from hisher soul heshe will agree that either willingly or unwillingly most of us doing very dishonest works may be some time for personal benefit or may be due to survive in a particular situation or may be sometime under pressure Now we are in a situation that dishonesty (corruption) is in our gene so we donrsquot think some dishonest work as to be dishonest From a service man to a daily wage labour from a politician to common people dishonesty has touched everybody in different form As an example let us consider a daily wage man and you employed him to work at your home but if you donrsquot observe him he definitely will not do his duty properly so that is also a kind of dishonesty Therefore to climb the ladder of progress we have to bring back our honesty Somehow we have to show the common people that how dishonesty is pulling us from our back and we are walking years after years but still in the same place If we become honest to some extent then at least we will be able to use the funds for various works properly and there will be progress

-Manab Sharma

----------------- ---------------

An oldest printing press

Therefore in my opinion to overcome all these factors public awareness and motivation of common people towards the right path of progress is the only solution So hereby I would like to through a query towards our honourable members that - is there anything that we can do which will have a direct physical impact to awake the people of our region from their deep sleep and also to make aware of power and extreme strength that the common people have with them

If somehow this can be done then we will see that politician or the group of people who nowadays most of the time seeks only individual benefits will not be able to motivate them rather general people will be motivating them and the nation will start to climb the ladder of progress

7 New activity

To run the forum smoothly to make it more organised and to speed up activities formation of a committeeteam is essential

The combined discussion of the moderators and senior members make the forum feel the importance of Advisors co-ordinator volunteer webmasters etc Of course it needs more discussion and will be approved by poll

8 Guidelines for the forum The moderators formulated some guidelines for the forum which are as follow These guidelines were kept open for discussion in the forum With time and need the guidelines will be changed

i Anybody in the forum can start a meaningful and constructive discussion after discussion with moderators

ii Comments from the individual members do not necessarily reflect the view of the forum

iii No single moderator can take a crucial decision All decision would be taken by the moderators unanimously or together with the group as majority

iv One should not write any massage to the forum addressing some particular members It should always start with Dear all Dear esteemed members etc

v If one has to write a mail to a particular member shehe should write personal mail

vi Everyone has the freedom to speak but that doesnrsquot mean that one should attack personally Of course we do have differences There can be debate or discussion but it should always be a healthy one Onersquos personal comment should be written in such a way that it reflects hisher view only It should not touch others sentimentsemotions

vii Whenever we are in a forum society home members should be sensitive caring enough to their comments so that it does not hurt sentiment of any second members

viii Members should not post greetings messages (Bihu wish New Year wish etc) to the forum

ix Members should post authentic news only The source of the news should be authentic No controversial news or comment should be posted to the forum

x Our main aim is to discuss science to generate science consciousness scientific temperament sensitivity awareness and research for the benefit of the mankind in general and North East India in particular

xi In severe cases moderators can take a hard decision unanimously or majority wise ( may be through poll) (This point needs to be accepted by all the members)

While sending request or while fulfilling request for articles please follow the following points

bull The forum has been formed to help each other When a member requests articlesliterature to forum members of the forum are always happy to help the person by supplying the articles But at

N E Quest Volume 2 Issue 4 January 2009 7

Newsletter of North East India Research Forum

this stage we have to keep in mind that the article should be sent to the person who requested it not to the whole forum as it creates lots of unnecessary mails in the message box of the forum Moreover if it continues it become a irritation also for many members

bull It is also the duty of the person who requests article to acknowledge the person who helped himher This can be done by writing Request fulfilled by in the subject area while composing the mail and write a thanking message in the main message board Once this is done then if some other members want to send the article will know about the status of the request This will also help members in keeping mailbox clean

bull Before asking for article heshe should always check hisher instituteuniversity libraries (online resources) If it is not available or accessible then only the member should request to the forum

bull Moreover sending articles (copyright protected articles) to the open forum violates copyright act So please send the article to the person who requests not to everybody through this open forum

News from Mars Scientists have announced the discovery of substantial deposits of carbonate rocks on Mars Although the new rocks are not from the bed of a long-lost ocean as would once have been hoped the discovery is still fanning hopes that the rocks might hold preserved traces of organic matter from the

planets early history The carbonates were discovered using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) an instrument carried on NASAs Mars Reconnaissance Orbiter (MRO) CRISM results show evidence of magnesium carbonate (magnesite) in an area known as Nili Fossae that sits on the edge of Isidis Planitia one of the planets great impact basins (for details Ehlmann B L et al Science 322 2008 1828)

More than four years after researchers first said they had found methane gas on Mars a scientist claims that he has nailed the controversial detection

and identified key sources of the gas On Earth methane is mostly biological in origin on Mars it could signal microbes living deep underground The latest work suggests that martian methane is concentrated in both space and time mdash at a handful of hotspots hundreds of kilometres across plumes of methane bloom and dissipate in less than a year Scientist Michael Mumma a spectroscopy expert obtained data from telescopes in Hawaii and Chile that supported the notion of methane hotspots According to the scientist he has confirmed the presence of methane by matching four lines in his infrared spectra of the planets atmosphere to the characteristic signature of methane mdash a more definite determination than previous analyses mdash and

found more evidence that the methane is localized in discrete hotspots which peak at levels of 60 parts per billion The more important observations is the short lifetimes of the plumes Previously methane was thought to be destroyed in the atmosphere by sunlight mdash a slow process that allows the gas to mix in the atmosphere and persist for about 300 years A global level of 10 parts per billion and a lifetime of hundreds of years means that a few hundred tonnes of methane are entering the atmosphere each year the work of a few thousand cows But plumes of 60 parts per billion that live for less than a year imply a methane-production rate several orders of magnitude higher This is a big deal says Sushil Atreya of the University of Michigan in Ann Arbor a co-author of the 2004 Mars Express paper At the moment whether the methane plumes are biological or geological in origin is impossible to know at the moment But NASAs next Mars rover will be able to analyse at levels of parts per trillion the fractional concentrations of the carbon isotopes in each methane molecule Life on Earth prefers to process lighter carbon-12 atoms And so on Mars methane freighted with carbon-12 could be a sign of a biological

NE herb ndash remedy to Malaria

In search of alternative drugs for Chloroquine recently DRDO reported a probability of development of an anti-malarial drug from a herb available in the North East Dr W Selvamurthy chief controller of the DRDO revelled Six months back we discovered the anti-malarial qualities in a herb Gommstema found exclusively in the North East DRDO claims the drug would remove the Plasmodium Vivax strains from the blood of the affected person The drug is now on its clinical trial after it had been tested and approved by Dr Padmanabhan of IIS Bangalore He said ldquoWe are also identifying the chemical structure of the herb so that it could be cultivated for mass production of the drugrdquo (Source-PTI)

Enzyme that degrade fat Researchers at the University of California Berkeley under the supervision of Prof Hei Sook Sul identified a new enzyme that plays a far more important role than expected in controlling the breakdown of fat The new enzyme within fat cells that is a key regulator of fat metabolism and body weight making it a promising target in the search for a treatment for human obesity In a new study to be published Jan 11 in the journal Nature Medicine researchers report that mice that have had this enzyme disabled remained lean despite eating a high-fat diet and losing a hormone that suppresses appetite The enzyme in the spotlight adipose-specific phospholipase A2 (AdPLA) is found in abundance only in fat tissue AdPLA sets off a chain of events that increases levels of a signalling molecule called prostaglandin E2 (PGE2) which suppresses the breakdown of fat Mice that have no AdPLA have lower PGE2 levels and a higher rate of fat metabolism

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

Seco

or microbes are secondary

Need

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

News from Mars Scientists have announced the discovery of substantial deposits of carbonate rocks on Mars Although the new rocks are not from the bed of a long-lost ocean as would once have been hoped the discovery is still fanning hopes that the rocks might hold preserved traces of organic matter from the

planets early history The carbonates were discovered using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) an instrument carried on NASAs Mars Reconnaissance Orbiter (MRO) CRISM results show evidence of magnesium carbonate (magnesite) in an area known as Nili Fossae that sits on the edge of Isidis Planitia one of the planets great impact basins (for details Ehlmann B L et al Science 322 2008 1828)

More than four years after researchers first said they had found methane gas on Mars a scientist claims that he has nailed the controversial detection

and identified key sources of the gas On Earth methane is mostly biological in origin on Mars it could signal microbes living deep underground The latest work suggests that martian methane is concentrated in both space and time mdash at a handful of hotspots hundreds of kilometres across plumes of methane bloom and dissipate in less than a year Scientist Michael Mumma a spectroscopy expert obtained data from telescopes in Hawaii and Chile that supported the notion of methane hotspots According to the scientist he has confirmed the presence of methane by matching four lines in his infrared spectra of the planets atmosphere to the characteristic signature of methane mdash a more definite determination than previous analyses mdash and

found more evidence that the methane is localized in discrete hotspots which peak at levels of 60 parts per billion The more important observations is the short lifetimes of the plumes Previously methane was thought to be destroyed in the atmosphere by sunlight mdash a slow process that allows the gas to mix in the atmosphere and persist for about 300 years A global level of 10 parts per billion and a lifetime of hundreds of years means that a few hundred tonnes of methane are entering the atmosphere each year the work of a few thousand cows But plumes of 60 parts per billion that live for less than a year imply a methane-production rate several orders of magnitude higher This is a big deal says Sushil Atreya of the University of Michigan in Ann Arbor a co-author of the 2004 Mars Express paper At the moment whether the methane plumes are biological or geological in origin is impossible to know at the moment But NASAs next Mars rover will be able to analyse at levels of parts per trillion the fractional concentrations of the carbon isotopes in each methane molecule Life on Earth prefers to process lighter carbon-12 atoms And so on Mars methane freighted with carbon-12 could be a sign of a biological

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

7 New activity

To run the forum smoothly to make it more organised and to speed up activities formation of a committeeteam is essential

The combined discussion of the moderators and senior members make the forum feel the importance of Advisors co-ordinator volunteer webmasters etc Of course it needs more discussion and will be approved by poll

8 Guidelines for the forum The moderators formulated some guidelines for the forum which are as follow These guidelines were kept open for discussion in the forum With time and need the guidelines will be changed

i Anybody in the forum can start a meaningful and constructive discussion after discussion with moderators

ii Comments from the individual members do not necessarily reflect the view of the forum

iii No single moderator can take a crucial decision All decision would be taken by the moderators unanimously or together with the group as majority

iv One should not write any massage to the forum addressing some particular members It should always start with Dear all Dear esteemed members etc

v If one has to write a mail to a particular member shehe should write personal mail

vi Everyone has the freedom to speak but that doesnrsquot mean that one should attack personally Of course we do have differences There can be debate or discussion but it should always be a healthy one Onersquos personal comment should be written in such a way that it reflects hisher view only It should not touch others sentimentsemotions

vii Whenever we are in a forum society home members should be sensitive caring enough to their comments so that it does not hurt sentiment of any second members

viii Members should not post greetings messages (Bihu wish New Year wish etc) to the forum

ix Members should post authentic news only The source of the news should be authentic No controversial news or comment should be posted to the forum

x Our main aim is to discuss science to generate science consciousness scientific temperament sensitivity awareness and research for the benefit of the mankind in general and North East India in particular

xi In severe cases moderators can take a hard decision unanimously or majority wise ( may be through poll) (This point needs to be accepted by all the members)

While sending request or while fulfilling request for articles please follow the following points

bull The forum has been formed to help each other When a member requests articlesliterature to forum members of the forum are always happy to help the person by supplying the articles But at

N E Quest Volume 2 Issue 4 January 2009 7

Newsletter of North East India Research Forum

this stage we have to keep in mind that the article should be sent to the person who requested it not to the whole forum as it creates lots of unnecessary mails in the message box of the forum Moreover if it continues it become a irritation also for many members

bull It is also the duty of the person who requests article to acknowledge the person who helped himher This can be done by writing Request fulfilled by in the subject area while composing the mail and write a thanking message in the main message board Once this is done then if some other members want to send the article will know about the status of the request This will also help members in keeping mailbox clean

bull Before asking for article heshe should always check hisher instituteuniversity libraries (online resources) If it is not available or accessible then only the member should request to the forum

bull Moreover sending articles (copyright protected articles) to the open forum violates copyright act So please send the article to the person who requests not to everybody through this open forum

News from Mars Scientists have announced the discovery of substantial deposits of carbonate rocks on Mars Although the new rocks are not from the bed of a long-lost ocean as would once have been hoped the discovery is still fanning hopes that the rocks might hold preserved traces of organic matter from the

planets early history The carbonates were discovered using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) an instrument carried on NASAs Mars Reconnaissance Orbiter (MRO) CRISM results show evidence of magnesium carbonate (magnesite) in an area known as Nili Fossae that sits on the edge of Isidis Planitia one of the planets great impact basins (for details Ehlmann B L et al Science 322 2008 1828)

More than four years after researchers first said they had found methane gas on Mars a scientist claims that he has nailed the controversial detection

and identified key sources of the gas On Earth methane is mostly biological in origin on Mars it could signal microbes living deep underground The latest work suggests that martian methane is concentrated in both space and time mdash at a handful of hotspots hundreds of kilometres across plumes of methane bloom and dissipate in less than a year Scientist Michael Mumma a spectroscopy expert obtained data from telescopes in Hawaii and Chile that supported the notion of methane hotspots According to the scientist he has confirmed the presence of methane by matching four lines in his infrared spectra of the planets atmosphere to the characteristic signature of methane mdash a more definite determination than previous analyses mdash and

found more evidence that the methane is localized in discrete hotspots which peak at levels of 60 parts per billion The more important observations is the short lifetimes of the plumes Previously methane was thought to be destroyed in the atmosphere by sunlight mdash a slow process that allows the gas to mix in the atmosphere and persist for about 300 years A global level of 10 parts per billion and a lifetime of hundreds of years means that a few hundred tonnes of methane are entering the atmosphere each year the work of a few thousand cows But plumes of 60 parts per billion that live for less than a year imply a methane-production rate several orders of magnitude higher This is a big deal says Sushil Atreya of the University of Michigan in Ann Arbor a co-author of the 2004 Mars Express paper At the moment whether the methane plumes are biological or geological in origin is impossible to know at the moment But NASAs next Mars rover will be able to analyse at levels of parts per trillion the fractional concentrations of the carbon isotopes in each methane molecule Life on Earth prefers to process lighter carbon-12 atoms And so on Mars methane freighted with carbon-12 could be a sign of a biological

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

First Gene Discovered For Most Common Form of Epilepsy

An international team of researchers led by investigators at Columbia University Medical Center has uncovered the first gene linked to the most common

type of epilepsy called Rolandic epilepsy The finding is the first step in unlocking the causes of common childhood epilepsies (a common chronic neurological disorder characterized by recurrent unprovoked seizures) and developing more effective treatments Children with Rolandic and other types of epilepsies are usually treated with drugs that prevent seizures by suppressing electrical activity in the entire brain Pediatric neurologist Deb Pal MD PhD Columbia University research scientist in the Department of Psychiatry at the College of Physicians amp Surgeons said Most epilepsies have a genetic influence much of which has yet to be discovered If we knew the actual genetic causes then we could try to stop or reverse the processes that lead to seizures and other neurological impairments This finding will hopefully help lead us to the right intervention The findings also offer possible insights into the causes of attention deficit hyperactivity disorder (ADHD) speech dyspraxia (a speech disorder in which a person has a delay in speech development due to motor coordination difficulties) and developmental coordination disorder (DCD) Findings will be published in an advance online issue of the European Journal of Human Genetics on January 28 2009 (Sourcewwwsciencedailycom)

MS Swaminathan father of Indiarsquos green revolution put forwarded the concept for the region to adopt to preserve its rich bio-

diversity in his lecture on the second day of the National Science Congress on the North Eastern Hill University (Nehu) campus According to Swaminathan ldquoEvergreen revolution would mean the need to carry out organic agriculture maintaining the ecology of the Northeastrdquo explaining that every species of flora was precious and needed care ldquoThe Northeast is one of the 12 mega-bio diversity areas of the country and this itself indicates the urgency of tapping the regionrsquos potential by the indigenous communitiesrdquo He also called for tapping floriculture in the Northeast as the orchids and other flowers are

in high demand in India and abroad He said orchids are believed to have evolved in the region ldquoOf the 1300 species belonging to 158 genera reported from India the Northeast has the highest concentration with nearly 700 species of orchidsrdquo Attention should be given to conserve many vanishing species like the 34 species of orchids from the region that are listed among are should be in much priority He also mentioned the ldquosacred grovesrdquo of Meghalaya mdash the community-preserved trees mdash and said this concept of local conservation tradition

Seco

or microbes are secondary

Need

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Spices plant has also tremendous demand in the state as well as in whole country A few spices species cultivated by the tribal people are Allium turberosum Amomum aromaitcum Amomum subulatum Curcuma amada Curcuma Zedoaria Piper longum Piper peepuloides Piper mullesua etc

Timber yielding plants The economy of the state depends upon

the timber plant of the state The timber of this state had great demand throughout the country The bamboo canes also play an important role in the economy of the people of the state A few important timber yielding plant are Actinodaphne obovata Albizia lucida Alostonia schlaris Artocarpus lacucha Biscofia javanica Bombax ceiba Cinnamommum glaucescens Dipterocarpus retusus Gynocardia odorata Kydia calycina Pinus roxburghii Quercus griffithii etc A few common bamboo species are Bambusa pallida Bambusa tulda Dendrocalamus hamiltoni Dendrocalamus strictus Melocanna baccifera etc Another a few cane species are Calamus flagellum Calamus floribundus Calamus latifolius etc

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

bull Best paper awards

7 New activity

To run the forum smoothly to make it more organised and to speed up activities formation of a committeeteam is essential

The combined discussion of the moderators and senior members make the forum feel the importance of Advisors co-ordinator volunteer webmasters etc Of course it needs more discussion and will be approved by poll

8 Guidelines for the forum The moderators formulated some guidelines for the forum which are as follow These guidelines were kept open for discussion in the forum With time and need the guidelines will be changed

i Anybody in the forum can start a meaningful and constructive discussion after discussion with moderators

ii Comments from the individual members do not necessarily reflect the view of the forum

iii No single moderator can take a crucial decision All decision would be taken by the moderators unanimously or together with the group as majority

iv One should not write any massage to the forum addressing some particular members It should always start with Dear all Dear esteemed members etc

v If one has to write a mail to a particular member shehe should write personal mail

vi Everyone has the freedom to speak but that doesnrsquot mean that one should attack personally Of course we do have differences There can be debate or discussion but it should always be a healthy one Onersquos personal comment should be written in such a way that it reflects hisher view only It should not touch others sentimentsemotions

vii Whenever we are in a forum society home members should be sensitive caring enough to their comments so that it does not hurt sentiment of any second members

viii Members should not post greetings messages (Bihu wish New Year wish etc) to the forum

ix Members should post authentic news only The source of the news should be authentic No controversial news or comment should be posted to the forum

x Our main aim is to discuss science to generate science consciousness scientific temperament sensitivity awareness and research for the benefit of the mankind in general and North East India in particular

xi In severe cases moderators can take a hard decision unanimously or majority wise ( may be through poll) (This point needs to be accepted by all the members)

While sending request or while fulfilling request for articles please follow the following points

bull The forum has been formed to help each other When a member requests articlesliterature to forum members of the forum are always happy to help the person by supplying the articles But at

N E Quest Volume 2 Issue 4 January 2009 7

Newsletter of North East India Research Forum

this stage we have to keep in mind that the article should be sent to the person who requested it not to the whole forum as it creates lots of unnecessary mails in the message box of the forum Moreover if it continues it become a irritation also for many members

bull It is also the duty of the person who requests article to acknowledge the person who helped himher This can be done by writing Request fulfilled by in the subject area while composing the mail and write a thanking message in the main message board Once this is done then if some other members want to send the article will know about the status of the request This will also help members in keeping mailbox clean

bull Before asking for article heshe should always check hisher instituteuniversity libraries (online resources) If it is not available or accessible then only the member should request to the forum

bull Moreover sending articles (copyright protected articles) to the open forum violates copyright act So please send the article to the person who requests not to everybody through this open forum

News from Mars Scientists have announced the discovery of substantial deposits of carbonate rocks on Mars Although the new rocks are not from the bed of a long-lost ocean as would once have been hoped the discovery is still fanning hopes that the rocks might hold preserved traces of organic matter from the

planets early history The carbonates were discovered using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) an instrument carried on NASAs Mars Reconnaissance Orbiter (MRO) CRISM results show evidence of magnesium carbonate (magnesite) in an area known as Nili Fossae that sits on the edge of Isidis Planitia one of the planets great impact basins (for details Ehlmann B L et al Science 322 2008 1828)

More than four years after researchers first said they had found methane gas on Mars a scientist claims that he has nailed the controversial detection

and identified key sources of the gas On Earth methane is mostly biological in origin on Mars it could signal microbes living deep underground The latest work suggests that martian methane is concentrated in both space and time mdash at a handful of hotspots hundreds of kilometres across plumes of methane bloom and dissipate in less than a year Scientist Michael Mumma a spectroscopy expert obtained data from telescopes in Hawaii and Chile that supported the notion of methane hotspots According to the scientist he has confirmed the presence of methane by matching four lines in his infrared spectra of the planets atmosphere to the characteristic signature of methane mdash a more definite determination than previous analyses mdash and

found more evidence that the methane is localized in discrete hotspots which peak at levels of 60 parts per billion The more important observations is the short lifetimes of the plumes Previously methane was thought to be destroyed in the atmosphere by sunlight mdash a slow process that allows the gas to mix in the atmosphere and persist for about 300 years A global level of 10 parts per billion and a lifetime of hundreds of years means that a few hundred tonnes of methane are entering the atmosphere each year the work of a few thousand cows But plumes of 60 parts per billion that live for less than a year imply a methane-production rate several orders of magnitude higher This is a big deal says Sushil Atreya of the University of Michigan in Ann Arbor a co-author of the 2004 Mars Express paper At the moment whether the methane plumes are biological or geological in origin is impossible to know at the moment But NASAs next Mars rover will be able to analyse at levels of parts per trillion the fractional concentrations of the carbon isotopes in each methane molecule Life on Earth prefers to process lighter carbon-12 atoms And so on Mars methane freighted with carbon-12 could be a sign of a biological

Enzyme that degrade fat Researchers at the University of California Berkeley under the supervision of Prof Hei Sook Sul identified a new enzyme that plays a far more important role than expected in controlling the breakdown of fat The new enzyme within fat cells that is a key regulator of fat metabolism and body weight making it a promising target in the search for a treatment for human obesity In a new study to be published Jan 11 in the journal Nature Medicine researchers report that mice that have had this enzyme disabled remained lean despite eating a high-fat diet and losing a hormone that suppresses appetite The enzyme in the spotlight adipose-specific phospholipase A2 (AdPLA) is found in abundance only in fat tissue AdPLA sets off a chain of events that increases levels of a signalling molecule called prostaglandin E2 (PGE2) which suppresses the breakdown of fat Mice that have no AdPLA have lower PGE2 levels and a higher rate of fat metabolism

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

First Gene Discovered For Most Common Form of Epilepsy

An international team of researchers led by investigators at Columbia University Medical Center has uncovered the first gene linked to the most common

type of epilepsy called Rolandic epilepsy The finding is the first step in unlocking the causes of common childhood epilepsies (a common chronic neurological disorder characterized by recurrent unprovoked seizures) and developing more effective treatments Children with Rolandic and other types of epilepsies are usually treated with drugs that prevent seizures by suppressing electrical activity in the entire brain Pediatric neurologist Deb Pal MD PhD Columbia University research scientist in the Department of Psychiatry at the College of Physicians amp Surgeons said Most epilepsies have a genetic influence much of which has yet to be discovered If we knew the actual genetic causes then we could try to stop or reverse the processes that lead to seizures and other neurological impairments This finding will hopefully help lead us to the right intervention The findings also offer possible insights into the causes of attention deficit hyperactivity disorder (ADHD) speech dyspraxia (a speech disorder in which a person has a delay in speech development due to motor coordination difficulties) and developmental coordination disorder (DCD) Findings will be published in an advance online issue of the European Journal of Human Genetics on January 28 2009 (Sourcewwwsciencedailycom)

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

News from Mars Scientists have announced the discovery of substantial deposits of carbonate rocks on Mars Although the new rocks are not from the bed of a long-lost ocean as would once have been hoped the discovery is still fanning hopes that the rocks might hold preserved traces of organic matter from the

planets early history The carbonates were discovered using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) an instrument carried on NASAs Mars Reconnaissance Orbiter (MRO) CRISM results show evidence of magnesium carbonate (magnesite) in an area known as Nili Fossae that sits on the edge of Isidis Planitia one of the planets great impact basins (for details Ehlmann B L et al Science 322 2008 1828)

More than four years after researchers first said they had found methane gas on Mars a scientist claims that he has nailed the controversial detection

and identified key sources of the gas On Earth methane is mostly biological in origin on Mars it could signal microbes living deep underground The latest work suggests that martian methane is concentrated in both space and time mdash at a handful of hotspots hundreds of kilometres across plumes of methane bloom and dissipate in less than a year Scientist Michael Mumma a spectroscopy expert obtained data from telescopes in Hawaii and Chile that supported the notion of methane hotspots According to the scientist he has confirmed the presence of methane by matching four lines in his infrared spectra of the planets atmosphere to the characteristic signature of methane mdash a more definite determination than previous analyses mdash and

found more evidence that the methane is localized in discrete hotspots which peak at levels of 60 parts per billion The more important observations is the short lifetimes of the plumes Previously methane was thought to be destroyed in the atmosphere by sunlight mdash a slow process that allows the gas to mix in the atmosphere and persist for about 300 years A global level of 10 parts per billion and a lifetime of hundreds of years means that a few hundred tonnes of methane are entering the atmosphere each year the work of a few thousand cows But plumes of 60 parts per billion that live for less than a year imply a methane-production rate several orders of magnitude higher This is a big deal says Sushil Atreya of the University of Michigan in Ann Arbor a co-author of the 2004 Mars Express paper At the moment whether the methane plumes are biological or geological in origin is impossible to know at the moment But NASAs next Mars rover will be able to analyse at levels of parts per trillion the fractional concentrations of the carbon isotopes in each methane molecule Life on Earth prefers to process lighter carbon-12 atoms And so on Mars methane freighted with carbon-12 could be a sign of a biological

NE herb ndash remedy to Malaria

In search of alternative drugs for Chloroquine recently DRDO reported a probability of development of an anti-malarial drug from a herb available in the North East Dr W Selvamurthy chief controller of the DRDO revelled Six months back we discovered the anti-malarial qualities in a herb Gommstema found exclusively in the North East DRDO claims the drug would remove the Plasmodium Vivax strains from the blood of the affected person The drug is now on its clinical trial after it had been tested and approved by Dr Padmanabhan of IIS Bangalore He said ldquoWe are also identifying the chemical structure of the herb so that it could be cultivated for mass production of the drugrdquo (Source-PTI)

Enzyme that degrade fat Researchers at the University of California Berkeley under the supervision of Prof Hei Sook Sul identified a new enzyme that plays a far more important role than expected in controlling the breakdown of fat The new enzyme within fat cells that is a key regulator of fat metabolism and body weight making it a promising target in the search for a treatment for human obesity In a new study to be published Jan 11 in the journal Nature Medicine researchers report that mice that have had this enzyme disabled remained lean despite eating a high-fat diet and losing a hormone that suppresses appetite The enzyme in the spotlight adipose-specific phospholipase A2 (AdPLA) is found in abundance only in fat tissue AdPLA sets off a chain of events that increases levels of a signalling molecule called prostaglandin E2 (PGE2) which suppresses the breakdown of fat Mice that have no AdPLA have lower PGE2 levels and a higher rate of fat metabolism

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

News from Mars Scientists have announced the discovery of substantial deposits of carbonate rocks on Mars Although the new rocks are not from the bed of a long-lost ocean as would once have been hoped the discovery is still fanning hopes that the rocks might hold preserved traces of organic matter from the

planets early history The carbonates were discovered using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) an instrument carried on NASAs Mars Reconnaissance Orbiter (MRO) CRISM results show evidence of magnesium carbonate (magnesite) in an area known as Nili Fossae that sits on the edge of Isidis Planitia one of the planets great impact basins (for details Ehlmann B L et al Science 322 2008 1828)

More than four years after researchers first said they had found methane gas on Mars a scientist claims that he has nailed the controversial detection

and identified key sources of the gas On Earth methane is mostly biological in origin on Mars it could signal microbes living deep underground The latest work suggests that martian methane is concentrated in both space and time mdash at a handful of hotspots hundreds of kilometres across plumes of methane bloom and dissipate in less than a year Scientist Michael Mumma a spectroscopy expert obtained data from telescopes in Hawaii and Chile that supported the notion of methane hotspots According to the scientist he has confirmed the presence of methane by matching four lines in his infrared spectra of the planets atmosphere to the characteristic signature of methane mdash a more definite determination than previous analyses mdash and

found more evidence that the methane is localized in discrete hotspots which peak at levels of 60 parts per billion The more important observations is the short lifetimes of the plumes Previously methane was thought to be destroyed in the atmosphere by sunlight mdash a slow process that allows the gas to mix in the atmosphere and persist for about 300 years A global level of 10 parts per billion and a lifetime of hundreds of years means that a few hundred tonnes of methane are entering the atmosphere each year the work of a few thousand cows But plumes of 60 parts per billion that live for less than a year imply a methane-production rate several orders of magnitude higher This is a big deal says Sushil Atreya of the University of Michigan in Ann Arbor a co-author of the 2004 Mars Express paper At the moment whether the methane plumes are biological or geological in origin is impossible to know at the moment But NASAs next Mars rover will be able to analyse at levels of parts per trillion the fractional concentrations of the carbon isotopes in each methane molecule Life on Earth prefers to process lighter carbon-12 atoms And so on Mars methane freighted with carbon-12 could be a sign of a biological

Enzyme that degrade fat Researchers at the University of California Berkeley under the supervision of Prof Hei Sook Sul identified a new enzyme that plays a far more important role than expected in controlling the breakdown of fat The new enzyme within fat cells that is a key regulator of fat metabolism and body weight making it a promising target in the search for a treatment for human obesity In a new study to be published Jan 11 in the journal Nature Medicine researchers report that mice that have had this enzyme disabled remained lean despite eating a high-fat diet and losing a hormone that suppresses appetite The enzyme in the spotlight adipose-specific phospholipase A2 (AdPLA) is found in abundance only in fat tissue AdPLA sets off a chain of events that increases levels of a signalling molecule called prostaglandin E2 (PGE2) which suppresses the breakdown of fat Mice that have no AdPLA have lower PGE2 levels and a higher rate of fat metabolism

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

NE herb ndash remedy to Malaria

In search of alternative drugs for Chloroquine recently DRDO reported a probability of development of an anti-malarial drug from a herb available in the North East Dr W Selvamurthy chief controller of the DRDO revelled Six months back we discovered the anti-malarial qualities in a herb Gommstema found exclusively in the North East DRDO claims the drug would remove the Plasmodium Vivax strains from the blood of the affected person The drug is now on its clinical trial after it had been tested and approved by Dr Padmanabhan of IIS Bangalore He said ldquoWe are also identifying the chemical structure of the herb so that it could be cultivated for mass production of the drugrdquo (Source-PTI)

Enzyme that degrade fat Researchers at the University of California Berkeley under the supervision of Prof Hei Sook Sul identified a new enzyme that plays a far more important role than expected in controlling the breakdown of fat The new enzyme within fat cells that is a key regulator of fat metabolism and body weight making it a promising target in the search for a treatment for human obesity In a new study to be published Jan 11 in the journal Nature Medicine researchers report that mice that have had this enzyme disabled remained lean despite eating a high-fat diet and losing a hormone that suppresses appetite The enzyme in the spotlight adipose-specific phospholipase A2 (AdPLA) is found in abundance only in fat tissue AdPLA sets off a chain of events that increases levels of a signalling molecule called prostaglandin E2 (PGE2) which suppresses the breakdown of fat Mice that have no AdPLA have lower PGE2 levels and a higher rate of fat metabolism

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

First Gene Discovered For Most Common Form of Epilepsy

An international team of researchers led by investigators at Columbia University Medical Center has uncovered the first gene linked to the most common

type of epilepsy called Rolandic epilepsy The finding is the first step in unlocking the causes of common childhood epilepsies (a common chronic neurological disorder characterized by recurrent unprovoked seizures) and developing more effective treatments Children with Rolandic and other types of epilepsies are usually treated with drugs that prevent seizures by suppressing electrical activity in the entire brain Pediatric neurologist Deb Pal MD PhD Columbia University research scientist in the Department of Psychiatry at the College of Physicians amp Surgeons said Most epilepsies have a genetic influence much of which has yet to be discovered If we knew the actual genetic causes then we could try to stop or reverse the processes that lead to seizures and other neurological impairments This finding will hopefully help lead us to the right intervention The findings also offer possible insights into the causes of attention deficit hyperactivity disorder (ADHD) speech dyspraxia (a speech disorder in which a person has a delay in speech development due to motor coordination difficulties) and developmental coordination disorder (DCD) Findings will be published in an advance online issue of the European Journal of Human Genetics on January 28 2009 (Sourcewwwsciencedailycom)

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Successful test of GSLV

On 20th December 2008 Indian Space Research Organization (ISRO) has successfully conducted a test of its indigenous cryogenic (supercooled fuel) engine to be used in the next geosynchronous launch vehicle (GSLV-D3) launch in April 2009 for carrying the 23-tonne geo-stationary experimental satellite (GSAT) mission Typically hydrogen and oxygen are used which need to be held respectively below -253 degrees Celsius and -183 degrees Celsius to remain in liquid form The cryogenic engine develops a thrust of 73 kilo Newtons (kN) in vacuum with a specific impulse of 454 seconds (756 minutes) and can carry 22 tonnes Working on a staged combustion cycle with an integrated turbo-pump the engine will have 42000 rotations per minute (rpm) It also has two steering engines developing a thrust of 2 kN each to enable three-axis control of the launch vehicle during the flight mission According to the statement of ISRO The hot test was carried out for 200 seconds (333 minutes) during which the engine was operated in the nominal and 13 percent up-rated thrust regimes All the propulsion parameters were satisfactory and matched with predictions Cryogenic engine technology is currently present only in Russia and the US The semi-cryogenic engines will facilitate applications for future space missions like the reusable launch vehicle the unified launch vehicle and the vehicle for inter-planetary missions Chidambaram added The central government has already approved the development of semi-cryogenic engines for space transportation at a cost of Rs1798 crore (approx Rs18 billion) with a foreign exchange component of Rs588 crore (Rs588 billion)

ISROrsquos next dream 2015

Indian Space Research Organisation (ISRO) is planning to send its first manned flight into space by 2015 K Radhakrishnan Member of the Space Commission and Director of Vikram Sarabhai Space Centre said that the proposal has been sent to the government and approval was being awaited According to ISRO the space craft will carry two crew and

suppose to orbit around 200 km away from Earth The scientist said ISRO was on the process of developing sophisticated versions of the PSLV launch vehicles

NE herb ndash remedy to Malaria

In search of alternative drugs for Chloroquine recently DRDO reported a probability of development of an anti-malarial drug from a herb available in the North East Dr W Selvamurthy chief controller of the DRDO revelled Six months back we discovered the anti-malarial qualities in a herb Gommstema found exclusively in the North East DRDO claims the drug would remove the Plasmodium Vivax strains from the blood of the affected person The drug is now on its clinical trial after it had been tested and approved by Dr Padmanabhan of IIS Bangalore He said ldquoWe are also identifying the chemical structure of the herb so that it could be cultivated for mass production of the drugrdquo (Source-PTI)

Enzyme that degrade fat Researchers at the University of California Berkeley under the supervision of Prof Hei Sook Sul identified a new enzyme that plays a far more important role than expected in controlling the breakdown of fat The new enzyme within fat cells that is a key regulator of fat metabolism and body weight making it a promising target in the search for a treatment for human obesity In a new study to be published Jan 11 in the journal Nature Medicine researchers report that mice that have had this enzyme disabled remained lean despite eating a high-fat diet and losing a hormone that suppresses appetite The enzyme in the spotlight adipose-specific phospholipase A2 (AdPLA) is found in abundance only in fat tissue AdPLA sets off a chain of events that increases levels of a signalling molecule called prostaglandin E2 (PGE2) which suppresses the breakdown of fat Mice that have no AdPLA have lower PGE2 levels and a higher rate of fat metabolism

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Modification need in fMRI According to a new study carried out by Aniruddha Das and Yevgeniy Sirotin at Columbia University in New York reported that the popular brain-imaging

techniques may be painting a misleading picture of brain activity Scientists using techniques such as functional magnetic resonance imaging (fMRI) make the assumption that blood flow into a particular brain region is directly linked to the amount of activity in the cells of that region This is because active cells need more oxygen and blood ferries it to them but according to the report (Ref Sirotin Y B amp Das A Nature 457 2009 475ndash479) this is not necessarily the case The findings suggest that scientists who use fMRI may need to interpret their data differently concludes neuroscientist David Leopold at the National Institute of Mental Health in Bethesda Maryland (Ref Leopold D A Nature 457 2009 387ndash388) Most fMRI experiments with human subjects involve presenting visual stimuli at intervals and rely on lining up the blood flow in time with the stimuli Leopold explains But he adds the mismatch between neural activity and blood flow demonstrated in the paper is extreme Das indicates that it should be possible to design experiments that are not confounded by the extra signal But he warns what our work suggests is that what people interpret as attention in functional MRI may not reflect local changes in neuronal activity (Sourcehttpwwwnaturecomnews2009090121fullnews200948htmlB1)

Alge ndash future fuel The simplest organisms on the planet may be an alternative to the impending global fuel crisis In the coming fuel

crisis time researchers are trying to find alternative and the most popular has been biofuel oil derived from corn rape and soya But as indicated by Dr Richard Pike the chief executive of the Royal Society of Chemistry Typically the figure for the gross amount of

biodiesel produced per hectare excludes the cost of fertiliser harvesting transportation he says You actually end up with as little as one or two tons therefore the main hurdle for these is the cost effectiveness But recently it has been found that producing biofuel from algae would get around this problem because the organism neither competes for arable land nor requires nutrients Instead algae use sunlight and carbon dioxide to produce minute amounts of nutrients ndash lipids (fatty oils) ndash which can after processing be used as biodiesel Algae grow at a phenomenally fast rate and have a very high yield 10000 gallons of biodiesel per acre compared to 48 gallons from soya and 120 gallons from rape Recently Solazyme a synthetic biology firm in San Francisco has produced an algae-based kerosene suitable for commercial and military jet engines by using a strain of algae that produces an oil naturally analogous to aviation oil (Souecewwwtelegraphcouk)

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

New Catalyst Ethanol-powered Fuel Cells

A team of scientists at the US Department of Energyrsquos (DOE) Brookhaven National Laboratory in collaboration with researchers from the University of Delaware

and Yeshiva University has developed a new catalyst that could make ethanol-powered fuel cells feasible The highly efficient catalyst performs two crucial and previously unreachable steps needed to oxidize ethanol and produce clean energy in fuel cell reactions With the help of platinum and rhodium atoms on carbon-supported tin

dioxide nanoparticles the research teamrsquos electrocatalyst is capable of breaking carbon bonds at room temperature and efficiently oxidizing ethanol into carbon dioxide as the main reaction product Scientists claimed ldquoThe ability to split the carbon-carbon bond and generate CO2 at room temperature is a completely new feature of catalysis There are no other catalysts that can achieve this at practical potentialsrdquo (Source wwwsciencedailycom)

First Gene Discovered For Most Common Form of Epilepsy

An international team of researchers led by investigators at Columbia University Medical Center has uncovered the first gene linked to the most common

type of epilepsy called Rolandic epilepsy The finding is the first step in unlocking the causes of common childhood epilepsies (a common chronic neurological disorder characterized by recurrent unprovoked seizures) and developing more effective treatments Children with Rolandic and other types of epilepsies are usually treated with drugs that prevent seizures by suppressing electrical activity in the entire brain Pediatric neurologist Deb Pal MD PhD Columbia University research scientist in the Department of Psychiatry at the College of Physicians amp Surgeons said Most epilepsies have a genetic influence much of which has yet to be discovered If we knew the actual genetic causes then we could try to stop or reverse the processes that lead to seizures and other neurological impairments This finding will hopefully help lead us to the right intervention The findings also offer possible insights into the causes of attention deficit hyperactivity disorder (ADHD) speech dyspraxia (a speech disorder in which a person has a delay in speech development due to motor coordination difficulties) and developmental coordination disorder (DCD) Findings will be published in an advance online issue of the European Journal of Human Genetics on January 28 2009 (Sourcewwwsciencedailycom)

MS Swaminathan father of Indiarsquos green revolution put forwarded the concept for the region to adopt to preserve its rich bio-

diversity in his lecture on the second day of the National Science Congress on the North Eastern Hill University (Nehu) campus According to Swaminathan ldquoEvergreen revolution would mean the need to carry out organic agriculture maintaining the ecology of the Northeastrdquo explaining that every species of flora was precious and needed care ldquoThe Northeast is one of the 12 mega-bio diversity areas of the country and this itself indicates the urgency of tapping the regionrsquos potential by the indigenous communitiesrdquo He also called for tapping floriculture in the Northeast as the orchids and other flowers are

in high demand in India and abroad He said orchids are believed to have evolved in the region ldquoOf the 1300 species belonging to 158 genera reported from India the Northeast has the highest concentration with nearly 700 species of orchidsrdquo Attention should be given to conserve many vanishing species like the 34 species of orchids from the region that are listed among are should be in much priority He also mentioned the ldquosacred grovesrdquo of Meghalaya mdash the community-preserved trees mdash and said this concept of local conservation tradition

Need

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Spices plant has also tremendous demand in the state as well as in whole country A few spices species cultivated by the tribal people are Allium turberosum Amomum aromaitcum Amomum subulatum Curcuma amada Curcuma Zedoaria Piper longum Piper peepuloides Piper mullesua etc

Timber yielding plants The economy of the state depends upon

the timber plant of the state The timber of this state had great demand throughout the country The bamboo canes also play an important role in the economy of the people of the state A few important timber yielding plant are Actinodaphne obovata Albizia lucida Alostonia schlaris Artocarpus lacucha Biscofia javanica Bombax ceiba Cinnamommum glaucescens Dipterocarpus retusus Gynocardia odorata Kydia calycina Pinus roxburghii Quercus griffithii etc A few common bamboo species are Bambusa pallida Bambusa tulda Dendrocalamus hamiltoni Dendrocalamus strictus Melocanna baccifera etc Another a few cane species are Calamus flagellum Calamus floribundus Calamus latifolius etc

Wild ornamental plants Orchid of Arunachal Pradesh is very

famous all over the world The state represents highest number of Orchid in NE region A few species of orchid are Calanthe Coelogyne Cymbidium Dendrobium phaius Phalaenopsis etc one of the rarest orchids of the state is Paphiopedilum fairieanum It is also known as Ladyrsquos slipper It is found in West Kameng dist in the state Another a few endangered species are Cymbidium grandiflorum C longifolium C macrorhizon C mackinnoni etc

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Global warming could create dead zones in oceans

Scientists in Denmark say global warming could create dead zones (Low-oxygen areas known as dead zones) in oceans that could remain for thousands of years The study used a computer model to simulate global warming in over the next

100000 years The worst-case scenario mdash if emissions continue at their current rate mdash would have carbon dioxide concentrations increase to 1168 ppm by 2100 a three-fold increaseThe oceans would get warmer and water circulation would slow down which in turn diminishes the ability of oxygen to dissolve in sea water This would bring about a dramatic drop in oxygen levels in vast ocean tracts (Source ndash BBC)

CSIRs institute to get autonomous university status

The Council for Scientific and Industrial Research (CSIR)s upcoming Advanced Institute of Science and Technology

(AIST) got clearance by the Central Government on Thursday to be an autonomous university The university will like to offer many courses like various innovative courses that have never been offered in India The university will be spread across CSIRs 30 laboratories in the country (Source Express news service)

New Catalyst Ethanol-powered Fuel Cells

A team of scientists at the US Department of Energyrsquos (DOE) Brookhaven National Laboratory in collaboration with researchers from the University of Delaware

and Yeshiva University has developed a new catalyst that could make ethanol-powered fuel cells feasible The highly efficient catalyst performs two crucial and previously unreachable steps needed to oxidize ethanol and produce clean energy in fuel cell reactions With the help of platinum and rhodium atoms on carbon-supported tin

dioxide nanoparticles the research teamrsquos electrocatalyst is capable of breaking carbon bonds at room temperature and efficiently oxidizing ethanol into carbon dioxide as the main reaction product Scientists claimed ldquoThe ability to split the carbon-carbon bond and generate CO2 at room temperature is a completely new feature of catalysis There are no other catalysts that can achieve this at practical potentialsrdquo (Source wwwsciencedailycom)

First Gene Discovered For Most Common Form of Epilepsy

An international team of researchers led by investigators at Columbia University Medical Center has uncovered the first gene linked to the most common

type of epilepsy called Rolandic epilepsy The finding is the first step in unlocking the causes of common childhood epilepsies (a common chronic neurological disorder characterized by recurrent unprovoked seizures) and developing more effective treatments Children with Rolandic and other types of epilepsies are usually treated with drugs that prevent seizures by suppressing electrical activity in the entire brain Pediatric neurologist Deb Pal MD PhD Columbia University research scientist in the Department of Psychiatry at the College of Physicians amp Surgeons said Most epilepsies have a genetic influence much of which has yet to be discovered If we knew the actual genetic causes then we could try to stop or reverse the processes that lead to seizures and other neurological impairments This finding will hopefully help lead us to the right intervention The findings also offer possible insights into the causes of attention deficit hyperactivity disorder (ADHD) speech dyspraxia (a speech disorder in which a person has a delay in speech development due to motor coordination difficulties) and developmental coordination disorder (DCD) Findings will be published in an advance online issue of the European Journal of Human Genetics on January 28 2009 (Sourcewwwsciencedailycom)

Seco

Need

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

POEM It is our proud privilege to congratulate Mr Kamal Kumar Tanti for receiving the ldquoMunin Borkotoki Literary Awardrdquo for his poetry book Maarangburu Amar Pita and I am taking the opportunity to publish one of his award wining poem ldquoBhraman Kahinirdquo

Probably an exact translation of words that come out spontaneously form the heart of a poet is impossible still a creditable effort was taken by Geetika Phukan to translated it to English) Travelogue On the silent street in Salonah tea garden We lost our way Grieving at our grief An old Kachari said ldquoChildren follow your noses There are dreams on the way not reality At the end of the dreams there will be dawnrdquo We realized Looking for flowers is easier Than finding thorns Flowers do not make us feel They feel themselves Thorns do not feel their sharpness They make others feel As travelers We wanted to thank the Old Kachari So halfway through we killed him And left his blood for the vultures and crows The cuckoos loved us for that And finally we reached a land of swords

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

compound

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

in high demand in India and abroad He said orchids are believed to have evolved in the region ldquoOf the 1300 species belonging to 158 genera reported from India the Northeast has the highest concentration with nearly 700 species of orchidsrdquo Attention should be given to conserve many vanishing species like the 34 species of orchids from the region that are listed among are should be in much priority He also mentioned the ldquosacred grovesrdquo of Meghalaya mdash the community-preserved trees mdash and said this concept of local conservation tradition

Need

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

compound

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

GUEST COLUMN ioactive secondary metabolites from

selected plants and their endophytic B

microorganism

Dr Debananda Ningthoujam Prea

cluding cytotoxic and anticancer

Seco

or microbes are secondary

Need

for use in medicine agriculture industry and

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

POEM It is our proud privilege to congratulate Mr Kamal Kumar Tanti for receiving the ldquoMunin Borkotoki Literary Awardrdquo for his poetry book Maarangburu Amar Pita and I am taking the opportunity to publish one of his award wining poem ldquoBhraman Kahinirdquo

Probably an exact translation of words that come out spontaneously form the heart of a poet is impossible still a creditable effort was taken by Geetika Phukan to translated it to English) Travelogue On the silent street in Salonah tea garden We lost our way Grieving at our grief An old Kachari said ldquoChildren follow your noses There are dreams on the way not reality At the end of the dreams there will be dawnrdquo We realized Looking for flowers is easier Than finding thorns Flowers do not make us feel They feel themselves Thorns do not feel their sharpness They make others feel As travelers We wanted to thank the Old Kachari So halfway through we killed him And left his blood for the vultures and crows The cuckoos loved us for that And finally we reached a land of swords

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

compound

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

MS Swaminathan father of Indiarsquos green revolution put forwarded the concept for the region to adopt to preserve its rich bio-

diversity in his lecture on the second day of the National Science Congress on the North Eastern Hill University (Nehu) campus According to Swaminathan ldquoEvergreen revolution would mean the need to carry out organic agriculture maintaining the ecology of the Northeastrdquo explaining that every species of flora was precious and needed care ldquoThe Northeast is one of the 12 mega-bio diversity areas of the country and this itself indicates the urgency of tapping the regionrsquos potential by the indigenous communitiesrdquo He also called for tapping floriculture in the Northeast as the orchids and other flowers are

in high demand in India and abroad He said orchids are believed to have evolved in the region ldquoOf the 1300 species belonging to 158 genera reported from India the Northeast has the highest concentration with nearly 700 species of orchidsrdquo Attention should be given to conserve many vanishing species like the 34 species of orchids from the region that are listed among are should be in much priority He also mentioned the ldquosacred grovesrdquo of Meghalaya mdash the community-preserved trees mdash and said this concept of local conservation tradition

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Fig3 Streptomyces sp

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Spices plant has also tremendous demand in the state as well as in whole country A few spices species cultivated by the tribal people are Allium turberosum Amomum aromaitcum Amomum subulatum Curcuma amada Curcuma Zedoaria Piper longum Piper peepuloides Piper mullesua etc

Timber yielding plants The economy of the state depends upon

the timber plant of the state The timber of this state had great demand throughout the country The bamboo canes also play an important role in the economy of the people of the state A few important timber yielding plant are Actinodaphne obovata Albizia lucida Alostonia schlaris Artocarpus lacucha Biscofia javanica Bombax ceiba Cinnamommum glaucescens Dipterocarpus retusus Gynocardia odorata Kydia calycina Pinus roxburghii Quercus griffithii etc A few common bamboo species are Bambusa pallida Bambusa tulda Dendrocalamus hamiltoni Dendrocalamus strictus Melocanna baccifera etc Another a few cane species are Calamus flagellum Calamus floribundus Calamus latifolius etc

Wild ornamental plants Orchid of Arunachal Pradesh is very

famous all over the world The state represents highest number of Orchid in NE region A few species of orchid are Calanthe Coelogyne Cymbidium Dendrobium phaius Phalaenopsis etc one of the rarest orchids of the state is Paphiopedilum fairieanum It is also known as Ladyrsquos slipper It is found in West Kameng dist in the state Another a few endangered species are Cymbidium grandiflorum C longifolium C macrorhizon C mackinnoni etc

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Fig 2 Snake vine (Kennedia nigriscans)

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

sProblems and Prospects

mble Endophytes are microorganisms that

colonize the interior of healthy plants without causing any discernible disease symptoms to their host They can be isolated from plant tissues using strict surface sterilization methods (Schultz et al 1993 Zhi-Qi et al 2006) Compared to rhizosphere microbes endophytes have a more intimate relationship with the host plants Endophytes of late have been shown to produce diverse secondary metabolites incompounds

ndary metabolite definition Secondary metabolites sometimes

referred to as also as natural products are products of metabolism in plants animals and microorganisms that are not essential for normal growth development or reproduction of the organism ie these are metabolites that are lsquosecondaryrsquo to these normal life processes However it is increasingly becoming a debatable issue whether they are not absolutely essential or at lest not conferring any benefits whatsoever to the host organism(s) producing them One can only say that they are less essential to the normal functioning of the organism as compared to lsquoprimary metabolitesrsquo such as acetyl CoA or other products generated during glycolysis or TCA cycle etc Most bioactive compounds from plants metabolites

for novel bioactive metabolites

Worldwide people are threatened with new diseases such as cancer AIDS SARS Bird Flu Chikangunya etc associated with increasing environmental degradation climate change global warming and biodiversity erosion (Guo et al 2008) Hence there is imperative need for discovery of novel bioactive compounds Endophytes are promising sources of novel natural products

environment etc (Bacon et al 2000 Strobel amp Daisy 2003)

Each of the 300000 plant species on earth is host to one or more endophytes-bacteria fungi and actinobacteria (Strobel amp Daisy 2003) A rough estimate says there may be more than 1 million endophytic spp but only a handful of them have been characterized so far (Petrini 1991) This calls for renewed research efforts on endophytes all over the world Because of their versatility endophytic microorganisms have been appropriately called lsquochemical factoriesrsquo inside the plants (Owen amp Hundley 2004)

What are endophytes

The term endophyte (Gr Endon within phyton plant) was first coined by de Bary (de Bary 1866) and has become deeply embedded in the literature since then (Rai et al 2007)

Kado (1992) defined endophytes as ldquobacteria that reside within living plant tissues without doing substantive harm or gaining benefit other than securing residencerdquo Quispel (1992) considered endophytes as ldquobacteria that establish an endosymbiotic relationship with the plant whereby the plant receives an ecological benefit from the presence of the symbionts such as increased stress tolerance or plant growth promotion According to Hallman et al (1977) defined an endophyte as ldquoany bacterium that does not visibly harm the plant and can be isolated from surface-disinfected plant tissue or extracted from inside the plantrdquo This definition includes internal colonies-neutral as well as symbiontsrdquo

The definition of an endophyte has evolved over time (Conn amp Franco 2004) the most precise definition is ldquofungi or bacteria which for all or part of their life cycle invade the tissues of living plants and cause unapparent and asymptomatic infections entirely within plant tissues but cause no symptoms of disease (Wilson 1995)

The question remains however whether endophytes must be considered symbionts commensals mutualists or mild pathogens

Newsletter of North East India Research Forum

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

Fig 1 Gary

bull Antibacterial antibiotics bull Antifungal agents bull Antiviral compounds bull Antimalarial agents bull Herbicidal compounds bull Phytohormones bull Cytotoxic compounds

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

N E Quest Volume 2 Issue 4 January 2009 19

Newsletter of North East India Research Forum

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Fig 2 Snake vine (Kennedia nigriscans)

Fig3 Streptomyces sp

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Historical background One of the earliest publications on an

endophytic fungus was by Freeman (1904) referring to four other papers on endophytes published in 1898 Freeman found the endophytic fungus in Persian darnel (annual grass) Grasses with high endophyte content are often resistant to attack by certain herbivores or insects

Endophytes have then been isolated from several trees and horticultural plants eg apple and kiwifruit They have since then been found in virtually all plant species studied including medicinal plants

Other than bacterial pathogens there is no evidence that endophytic bacteria show the same host specificity though several fungal endophytes have been shown to exhibit host specificity eg fescue and ryegrass endophytes

The first actinobacterial endophyte isolate was Frankia which is N-fixing actinobacterium that forms actinorhizae with 8 families of angiosperms (Provorov et al 2002)

Strobel (Fig 1) et al at Montana State University USA has work intensively on endophytes esp fungi and explore them in several tropical rainforests According to him rainforests are the most promising sources of endophytes He has isolated several novel endophytic microbes producing bioactive compounds such as antibiotics

Promising screening targets which plants are promising

Plants in unique environments Plants with extreme longevity Plants with ethnobotanical history

Plants growing in biodiversity hotspots or in unique endemic locations

Plants in unique environments are more likely to host endophytes which can generate secondary metabolites that will assist the planetrsquos survival and healthy growth The promising biotopes for exploring endophytes are bull Tropical forests bull Arid lands bull Marine coral environments Endophytes from tropical regions produce significantly more bioactive secondary metabolites than those from temperate parts of the world (Shimizu et al 2000) It is to be expected that even plants growing in cultivated gardens host endophytes

Endophytic Microorganisms The major groups of endophytic microbes are

A Fungi B Bacteria C Actinomycetes

Some actinobacterial endophytes reported in the literature and their host plants are shown in Table 1

Bioactive metabolites Endophytic microorganisms have been shown to elaborate a plethora of bioactive metabolites They exhibit antimicrobial antiviral herbicidal plant growth promoting biocontrol antimalarial anticancer and various activities Some major categories of bioactive metabolites produce by endophytic microbes are as follows

bull Antibacterial antibiotics bull Antifungal agents bull Antiviral compounds bull Antimalarial agents bull Herbicidal compounds bull Phytohormones bull Cytotoxic compounds

Anticancer and cytotoxic agents from endophytes

Several endophytic microbes have recently been shown to be a promising source of anticancer agents Though fungal endophytes have been the predominant source earlier actinomycete endophytes have recently

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

POEM

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

become a prolific source of antitumor and cytotoxic compounds Table 2 lists some prominent anticancer metabolite-producing endophytic actinomycetes and their host plants

Besides cytotoxic compounds endophytic actinomycetes have proved to be versatile producers of a variety of secondary metabolites including antifungal antimalarial and antibacterial agents

Some biotechnologically significant bioactive metabolites elaborated by actinomycete endophytes that have been reported recently are shown in Table 3

Predominant endophytic actinomycetes Conn amp Franco (2003) isolated

actinobacteria from surface-sterilized wheat roots The major actinobacaterial genera based on cultivation methods were Streptomyces Microbispora Micromonospora and Nocardioides Many of these isolates were active against R solani Pythium spp and G graminis var tritici (In vivo and in planta Coombs et al 2004)

Dominant genera found based on T-RFLP patterns were bull Mycobacterium Rhodococcus

Streptomyces Nocardia and and Geodermatophilus in plants from Swedes flat soil

bull Streptomyces Arthrobacter Kineococcus-like isolates Amycolatopsis Nocardia in plants from Red loamy soil

bull Kitasatospora and Mycobacterium in plants from West flat soil

Actinomycetes identified as endophytes are Arthrobacter Kitasatospora Micromonospora Microbispora Nocardia Nocardioides Streptomyces and tsukamurella (Araujo et al 2002 from citrus Coombs amp Franko 2003 from wheat Doumbon et al 2001 from potato Garveva et al 2001 (potato) Sturz et al 1999 (potato)

Streptomyces is a ubiquitous endophyte and have been found in Ficus Dieffenbachia Allium porrum Brassica oteracera and Quercus sp (Sardi et al 1992)

The predominant actinobacterial genus based on molecular methods was Mycobacterium followed by Streptomyces

(Conn amp Franco 2004) whereas Streptomyces Microbispora Micromonospora and Nocardioides were found as dominant endophytic genera in cultivation-based approaches (Conn amp Franco 2004) An endophytic-host Snake vine (Kennedia nigriscans) is shown is Fig2 and an endophytic Streptomyces sp is shown on Fig 3

Applications of endophytes Besides producing antimicrobial

antimalarial and anticancer agents endophytic microbes especially fungal strains have also been recently considered as potential biological fumigants of fresh fruit Muscodor albus (fungal endophyte Fig4) volatiles inhibited and killed a wide range of storage pathogens-Bortrytis Colletotrichum Geotrichum Monilinia and Rhizopus Since M albus is a sterile mycelium and does not require direct contact with the crops to be treated it could be an attractive biological fumigant for controlling post-harvest diseases (Mercier amp Jimenez 2004)

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

POEM

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Conclusion

Endophytes are a poorly investigated group of microorganisms that represent an abundant and dependable source of bioactive and chemically novel compounds with potential for use in diverse medical agricultural and industrial applications (Strobel et al 2005) The mechanisms of endophyte function must be better understood to be more predictive about which higher plants to seek study and spend time isolating bioactive compounds This may facilitate the product discovery process

Although work on the utilization of this vast resource of poorly understood microbes has just begun it has already become obvious that an enormous potential for organism product and utilitarian discovery in this field holds exciting possibilities

One of the major problems facing the future of endophyte biology and natural product discovery is the rapidly diminishing rainforests and other forested areas which hold the greatest possible resource for acquiring novel microorganisms and their products The total land-mass of the world that currently supports rainforests is about the size of USA (Mittermeier et al 1999) Each year an area the size of Vermont or more is lost to anthropogenic activities

As entire plant species disappears few bother about the consequent loss of microbial diversity When a plant species disappears so too does its entire suite of associated endophytes

Introduction of endophyte research at Manipur University (MU) The research group at Molecular Biotechnology Research Laboratory (MBRL)

Dept of Biochemistry MU has already initiated isolation of rare endophytic actinomycetes from endemic plants including medicinal plants in Manipur Work on endophytes of Leibaak kundo and Damdawi plant have already begun Several interesting actinomycetes strains isolated amp bioactivity assay is being undertaken Endophytic actinomycetes from bamboo leaves and other promising plants in Manipur are our next target Fig4 Muscodor albus

What is to be done Multi-step processes are now needed to

secure information and life-forms before they continue to be lost Areas of our planet that are unique places housing biodiversity need immediate conservation Biodiversity-rich regions and areas such as North Eastern India and Manipur need to establish information bases of their biodiversity and at the same time begin to make regional and area-specific collection centres of medicinal plants and microorganisms (including endophytes) that live within these areas

Endophytes are only one example of a life form that holds enormous promise to impact many areas of human existence The problem of the loss of biodiversity should be one of concern to the entire world (Strobel et al 2005)

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

compound

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Spices plant has also tremendous demand in the state as well as in whole country A few spices species cultivated by the tribal people are Allium turberosum Amomum aromaitcum Amomum subulatum Curcuma amada Curcuma Zedoaria Piper longum Piper peepuloides Piper mullesua etc

Timber yielding plants The economy of the state depends upon

the timber plant of the state The timber of this state had great demand throughout the country The bamboo canes also play an important role in the economy of the people of the state A few important timber yielding plant are Actinodaphne obovata Albizia lucida Alostonia schlaris Artocarpus lacucha Biscofia javanica Bombax ceiba Cinnamommum glaucescens Dipterocarpus retusus Gynocardia odorata Kydia calycina Pinus roxburghii Quercus griffithii etc A few common bamboo species are Bambusa pallida Bambusa tulda Dendrocalamus hamiltoni Dendrocalamus strictus Melocanna baccifera etc Another a few cane species are Calamus flagellum Calamus floribundus Calamus latifolius etc

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

POEM

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

The World Class Universities and Rankings

-Dr Abdul Wahab Introduction

These days the term ldquoWorld Classrdquo is widely used in the discussions regarding the status of academic institutions or infrastructure With rapid industrialization many developing nations are wishing or investing to establish world class universities towards the aspiration of societal and educational excellence India is not an exception because in the modern world universities are the key elements in driving economic development and in facing the challenges of global competition But what does it mean to be a World Class University What makes a university world class What are the criteria for the world ranking of universities The dictionary defines world class as ranking among the foremost in the world of an international standard of excellence The concept of a world class university loosely reflects the norms and values of the worldrsquos dominant research-oriented academic institutions ndash especially the United States and the major Western European countries

Major factors of World Class Universities There is no absolute set of performance

criteria or benchmarks for world class universities However there is wide agreement on four major factors which are central to a world class university Those are (a) academic excellence and freedom (b) research development and dissemination of knowledge (c) permeable academic boundaries and (d) adequate funding and facilities (a) A world class university must show commitment to breadth and excellence in all fields of human inquiry ndash education ndash not simply in a particular branch or faculty Of course uniform excellence across all fields of study is an ideal that no university achieves in practice but it is a prerequisite ambition The excellence in education is directly linked to the resources and organization of undergraduate graduate and

professional instructions and educational opportunities for students All these require outstanding faculty high quality teaching and other instructional activities as well as highly prepared and motivated students These necessitate a vibrant internal self-governance system World class universities produce students who will go on to be leaders in all walks of life Academic freedom and an atmosphere of intellectual excitement are crucial to a world class university This means that professors and students must be free to pursue knowledge wherever it leads and to publish their work freely without fear of sanction by either academic of external authority In many countries academic freedom also extends to expression of opinions by members of the academic community on social and political issues (b) Excellence in research underpins the idea of a world class university That is world class universities engage in cutting-edge research whilst at the same time teaching the next generation Much of the talk about world class universities centers around the production of exciting discoveries and contributions to the economy and to human enrichment through the development of cultural knowledge So for making outstanding research possible top-quality professors and students are of course central And to attract and retain the best academic staff favorable working conditions must be available These include arrangements for job security ndash many countries call it tenure ndash and appropriate salaries and benefits (c) World class universities have permeable boundaries This means encouraging interdisciplinary research and teaching it means working with the private sector for example fostering and encouraging partnerships with industry and it means encouraging international collaboration at various levels World class universities look outward and think beyond conventional boundaries World class universities educate students more and more of whom will go on to live and work in a range of cultures and societies They must be well equipped for

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Spices plant has also tremendous demand in the state as well as in whole country A few spices species cultivated by the tribal people are Allium turberosum Amomum aromaitcum Amomum subulatum Curcuma amada Curcuma Zedoaria Piper longum Piper peepuloides Piper mullesua etc

Timber yielding plants The economy of the state depends upon

the timber plant of the state The timber of this state had great demand throughout the country The bamboo canes also play an important role in the economy of the people of the state A few important timber yielding plant are Actinodaphne obovata Albizia lucida Alostonia schlaris Artocarpus lacucha Biscofia javanica Bombax ceiba Cinnamommum glaucescens Dipterocarpus retusus Gynocardia odorata Kydia calycina Pinus roxburghii Quercus griffithii etc A few common bamboo species are Bambusa pallida Bambusa tulda Dendrocalamus hamiltoni Dendrocalamus strictus Melocanna baccifera etc Another a few cane species are Calamus flagellum Calamus floribundus Calamus latifolius etc

Wild ornamental plants Orchid of Arunachal Pradesh is very

famous all over the world The state represents highest number of Orchid in NE region A few species of orchid are Calanthe Coelogyne Cymbidium Dendrobium phaius Phalaenopsis etc one of the rarest orchids of the state is Paphiopedilum fairieanum It is also known as Ladyrsquos slipper It is found in West Kameng dist in the state Another a few endangered species are Cymbidium grandiflorum C longifolium C macrorhizon C mackinnoni etc

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

life both from what is taught and from the other experiences or exposures offered to them (d) Adequate facilities for academic work are essential ndash the most advanced and creative research and the most innovative teaching must have access to well equipped libraries and laboratories as well as to the Internet and other electronic resources At the same time adequate funding must be available to support the research and teaching as well as the other functions of the university Maintaining a complex academic institution is always expensive and so support must be consistent and for long-term The cost of maintaining a research university continues to grow because of the increasing complexity and cost of scientific research Although research universities have the ability to generate significant funds through a variety of means but there is no substitute for consistent and substantial public financial support Without it developing and sustaining a world class university is impossible

International Ranking of Universities Several organizations provide

worldwide rankings of universities based on a range of academic and associated benchmarks Some of these are (a) The Academic Ranking of World Universities by Shanghai Jiao Tong University which is a major Chinese project to provide independent rankings of universities around the world primarily to measure the gap between Chinese and world class universities (b) The Times Higher Education a British publication which in association with Quacquarelli Symonds (THE-QS) annually publishes a list of 200 top-ranked universities from around the world (c) The Newsweek magazine of United States published a ranking of the Top 100 Global Universities in 2006 utilizing some selected criteria from the Academic Ranking of World Universities by Shanghai Jiao Tong University and The Times Higher Education as well as the additional criteria of library holdings (d) The Webometrics Ranking of world universities is compiled

by the Cybermetrics Lab a unit of the National Research Council the main public research body in Spain It is offering information about 4000 universities since 2004 according to their web-presence over a database of 16000 universities worldwide Institutions from developing countries benefit from this policy as they obtain knowledge of their current position even if they are not world class (eg the latest world ranking of IIT-Guwahati is 3770) (e) The Eacutecole nationale supeacuterieure des mines de Paris established the Professional Ranking of world universities in 2007 to measure the efficiency of each university on a professional basis Its main compilation criterion is the number of Chief Executive Officers in the 500 leading worldwide companies as measured by revenue who studied in each university

Among these rankings of universities two main studies and in fact much publicized and referred are the Academic Ranking of World Universities by Shanghai Jiao Tong University (SJTU) and the World University Rankings by Times Higher Education (THE-QS)

1 The Academic Ranking of World Universities by SJTU

The Academic Ranking of World Universities is compiled by the Institute of Higher Education at Shanghai Jiao Tong University starting from 2003 Table 1 shows the latest 20 top-ranked universities along with two ranked Indian universities Rankings are based upon several indicators of academic and research performance For each indicator the highest scoring institution is assigned a score of 100 and other institutions are calculated as a percentage of the top score The distribution of data for each indicator is examined for any significant distorting effect and standard statistical techniques are used to adjust the indicator if necessary Scores for each indicator are weighted as follows alumni winning Nobel Prizes and Field Medals (10 percent) which reflect education quality staff winning Nobel Prizes and Fields Medals (20 percent) and highly-cited

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

researchers in 21 broad subject categories (20 percent) which measure quality of faculty articles published in Nature and Science (20 percent) and article indexed in Science Citation Index Social Sciences Citation Index and Arts and Humanities Citation Index (20 percent) to account research output and the per capita academic performance (on the indicators above) of an institution (10 percent) An institutions rank reflects the number of institutions that sit above it

2 The World University Rankings by THE-QS

The THE-QS World University Rankings is an annual publication that ranks the Top 200 World Universities to present a multi-faceted view of the relative strengths of the worlds leading universities They have been running since 2004 identifying four pillars as the basis for evaluation like research quality teaching quality graduate employability and international outlook Accordingly the overall rankings are compiled based on the scores obtained from six distinct indicators (by their weightings) Academic Peer Review (40 percent) Employer Review (10 percent) Faculty Student Ratio (20 percent) Citations per Faculty (20 percent) International Faculty (5 percent) and International Students (5 percent) Table 2 shows the latest 20 top-ranked universities along with two ranked Indian institutions The current ranking (2008) was based on a survey of 6354 academics from across the world for the academic peer review score Weightings are applied both geographically and by discipline to ensure as fair a representative spread as possible The number of principal academic areas represented included science technology social science biomedicine and arts approximately equally represented in the survey Furthermore data were supplemented by opinions from the previous year to increase the consistency and reliability These are combined with a series of measures including the number of times that research papers are cited by academics staff-to-

student ratios number of students and staff from abroad and views of international employers on which universities they prefer to recruit from

Discussion and conclusion If one compares the two latest rankings

of universities (2008) the Harvard University is ranked unanimously as the top by both ndash finds some reliability apparently Cambridge is within the top 4 in both rankings California Institute of Technology is in the top 6 in both rankings Massachusetts Oxford Columbia and Chicago are all in the top 10 University of Tokyo is ranked 19 by both studies Although 14 universities are listed in the top 20 according to both rankings there are some large disparities between the two surveys Stanford University for instance is ranked number two by the SJTU ranking but placed at seventeen by the THE-QS ranking Another example is the University of Yale ranked number 11 by the SJTU while THE-QS ranked it next to Harvard There are five Californian universities ranked within 20 by the SJTU but no Californians are there within or near 20 in THE-QS ranking except California Institute of Technology

According to SJTU rankings 17 of the 20 top-ranked universities are in the US 2 are in the UK and 1 from Japan No Indian institution appeared within 300 nevertheless two institutions (IISc-Bangalore and IIT-Kharagpur) are ranked at 303-401 range While according to the THE-QS ranking the top 20 universities are in 5 countries 13 of them from US All the 200 top universities are in 33 countries including India and IIT-Delhi and IIT-Bombay are ranked at 154 and 174 respectively although they could not make a place in the top 500 universities ranked by SJTU Thus it is quite clear that with the exception of the reputational rankings of the top 10-12 institutions there is relatively wide disagreement on the status of other institutions

People speculate that the definition of a world class university is subjective The subjective nature of world class status means

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

flowering plants are found in the state Many species of Annonaceae piperaceae and Lauraceae of Arunachal Pradesh are not occurred other part of the country except NE region and Eastern Himalaya Some of the dominant genera of Arunachal Pradesh are Bulbophyllum (62 spp) Rhododendron (61 spp) Ficus (51 spp) Dendrobium (47 spp) Primula (40 spp) Agapetes (34 spp) Impatiens (33spp) Carex (31 spp) Eria (31 spp) Rubus (29 spp) etc

The state has large number of primitive flowering plants Some of the important primitive flowering plants of the state are Alnus nepalensis Aspidocarya uvifera Houttuynia cordata Illicium cambodianum Illicium griffithii Magnolia griffithii Magnolia pealiana Myrica esculanta Tetracentron sinense etc

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Spices plant has also tremendous demand in the state as well as in whole country A few spices species cultivated by the tribal people are Allium turberosum Amomum aromaitcum Amomum subulatum Curcuma amada Curcuma Zedoaria Piper longum Piper peepuloides Piper mullesua etc

Timber yielding plants The economy of the state depends upon

the timber plant of the state The timber of this state had great demand throughout the country The bamboo canes also play an important role in the economy of the people of the state A few important timber yielding plant are Actinodaphne obovata Albizia lucida Alostonia schlaris Artocarpus lacucha Biscofia javanica Bombax ceiba Cinnamommum glaucescens Dipterocarpus retusus Gynocardia odorata Kydia calycina Pinus roxburghii Quercus griffithii etc A few common bamboo species are Bambusa pallida Bambusa tulda Dendrocalamus hamiltoni Dendrocalamus strictus Melocanna baccifera etc Another a few cane species are Calamus flagellum Calamus floribundus Calamus latifolius etc

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Conservation of the flora All people habitat in Arunachal

Pradesh are tribal of different communities World over tribal population still stores a vast knowledge on utilization of local plants as medicine food items cultural activities and other specific uses The tribal communities draw their sustenance mainly from the forests which provide them food plants health caring resources expressing their traditional cultures and other material requirement

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

that institutions will attempt to address those dimensions that are considered in assessing reputations and that are visible In this respect research activity publications citations and major faculty awards are highly visible and measurable while the quality of the educational process is not Thus it is not surprising to see a focus on research criteria in the surveys and in the efforts of institutions to promote their importance and little or no attempt to measure and assess teaching quality or educational activities However despite the technical and methodological problems and limitations of the ranking systems these web-published academic rankings of world

universities have received great attention They present a picture of the leading higher institutions around the world and provide guidance for universities that are striving to improve their education quality under the competition of globalization

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

compound

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Flora of Arunachal Pradesh and its conservation An overview

- Chandan Tamuly Introduction

Arunachal Pradesh is known as one of the 18th ldquoBiodiversity Hotspotrdquo of the world having a geographical area of 83743 sq km and population of 1097968 (census 2001) the state has been the traditional habitat of tribal people of Paleo-Mongoloid stock speaking mostly the Tibeto-Burman group of Sino-Tibetan language The state is sparsely populated and is both biologically and ethically diverse The state is situated on the extreme northeastern tip of India between lat 2628 to 2930 N and long 9131 to 9730 E Total 51540 sq km is covered by the forest in the state

Arunachal Pradesh represent as ldquoCradle of flowering plantsrdquo and ldquoBiogeographical gatewayrdquo of biological resources The phytogeographical position irregular and soil have resulted in the formation of various ecological diversity which has influenced the rich and fascinating vegetation of the state

Background The History of evaluation of the Flora

of the state was quite old The European Botanist and Explorer visited the area from early 19th century (Buchanan-Hamilton 1820 Roxburgh 1820-24 Griffith 1847 Hooker 1854 1872-1897 Hooker amp Thomson 1855 Clarke 1889 Burkill 1924-25 1965 Kingdom Ward 1929 1960 etc) In 20th century some of the important documentreport booksjournal were published on this issue These are Botany of Abor Expendition by IH Burkill (1924-25) Botanical Expendition of Mishmi Hills by Kingdom Ward (1929-1931) A Sketch of vegetation of Aka hills by NLBor (1938) Lohit vally by Kingdom Ward (1953) Flora of Aka Hills by KP Biswas (1941) and Flora of Assam 5 Vols by Kajilal (1934-1940) And lately lots of contribution was given by the Scientistsexperts of Botanical survey of India State Forest Research Institute Itanagar Forest Research Institute

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Medicinal plants Medicinal plants have a greatest demand in all over the world These medicinal plant are used in different diseases like cut wound pain fever Dysentery body ache cough ulcer blood pressure toothache indigestion asthma etc Taxus baccata has very high demand in the pharmaceutucal chemistry This valuable medicinal plant is found in Arunachal Pradesh Most valuable anti cancer drug ldquoTaxolrdquo can be extracted from this plant An American famous Scientist KC Nicolaou succeeded in manufacturing ldquoTaxolrdquo synthetically In the case of lsquoTaxolrsquo there are good reasons to improve upon nature While natural Taxol has been shown to shrink cancers of the ovary as well as the breast it is a wonder drug Poor solubility of synthetic Taxol makes it hard to administer and tumor cells tend to develop resistance to the drug So the drug obtains from the natural lsquoTaxolrsquo may be possible to find one that is less toxic and more effective than synthetic lsquoTaxolrsquo The traditional knowledge of medicinal plants is becoming a potential source for the Pharmaceutical Industries So collection of these medicinal plants in the bulk amount for the industries has posed a great threat to the wild valuable medicinal plant of the state

Some of the common medicinal plants and their uses are Allium cepa (eye pain) Allium hookeri (cough cold) Alstonia scholaris (headache) Andrographis peneculata (dysentery) Artimesia indica (bodyache asthma) Buddleja asiatica (Inflammation) Curcuma caesia (diarrhea) Carex polycephala(fever) Clerodendrum colebrookianum (hypertension) Callicarpa arborea (rheumatism) Elastostemma rupestre(headache) Ficus infectoria (cuts amp wounds) Houttuynia cordata (cough) Piper longum (Tuberculosis) P nigram (fever) P pedicellatum (fracture of bone) P thomsonii (urinary disorder) Rhus javanica (Diarrhoea amp Dysentery) Spilanthes acemella(cuts amp wounds) S paniculata (pyorrhea amp toothache) Zanthoxylum armatum (pyorrhea amp toothache) Zehneria umbellate (Jaundice) etc Some of the very important bioactive constituents and its biological activities evaluated from the flora of the state

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

compound

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Vegetation Due to various climatic condition and

different altitude the state influenced a rich diversity of vegetation of the region The vegetation can be classified under following categories (i) Tropical (ii) Subtropical (iii) Temperate (iv) Alpine and Sub Alpine

(i)Tropical Forest The tropical forests area is confined up

to 900m above sea level This can be divided into three subtypes (a) Tropical evergreen forests (b) Tropical semi evergreen forest and (c) Tropical wet evergreen forest Some of the important plant species seen in tropical vegetation are Bischofia javanica Bombax ceiba Gynocardia odorata Leea robusta Lagerstroemia parviflora Turpinia nepalensis Quercus lamellosa Ardisia virens Maesa indica etc

(ii) Subtropical forests The subtropical forests are confined

within 900-1800m from the sea level It can be divided into two subtypes (a) Subtropical broad leave forest and (b) Subtropical pine forest Some of the examples of the plants available in these forests area are Actinodaphne obovata Ficus gaspurriniana Kidia calycina Michelia oblonga Pinus roxburghii and Pinus wallichiana etc

(iii) Temperate vegetation The forest in the belt is range 1800-

3500m in altitude It can also divide into two subtypes a) Temperate broad leaved forest and b) Temperate conifer Forest Some of the important plants of this zone are Rhododendron spp Illicium griffithii Lyonia ovalifolia Mahonia acanthiifolia etc Lichens bryophytes fungi and ferns dominate epiphytes flora are present in this region

(iv) Alpine and sub alpine This belt is range in altitude 3500-

5500m Since this area generally covers by snow in the winter season so the plant need special adaptation for survival in such area

The common species of this area are like Berberis asiatica Berberis wallichiana Abies spectabilis Vaccinium venosum Aconitum ferox Aconitum nagarum Arenaria spp Gentiana paralota Taxus wallichiana Pleione hookeriana Bulbophyllum spp Herminium longilobatum etc Many endangered species are also found in this area

Aquatic Vegetation is also very important natural resources of the state Some of the important hydrophytes growing in the marshes pools paddy fields are Alisma plantago Monocharia vaginalis Polygonum alatum Potamogeton nodosus Sagittaria sagittifolia Sanicula europea Utricularia bifida etc

Floristic diversity and its distribution The total geographical area cover by

Arunachal Pradesh is about 254 of the country More than 23 of the flowering plant and 7693 of the total families of India represent by the state It is interesting to note that enumerates 4500 species of angiosperms belonging to 1295 genera and 192 families represent from the state India is covered by about 17500 species in 2984 genera and 247 families The non flowering plants are also well known in the state Out of 1020 spceies of ferns occupying in India 452 species are recorded in Arunachal Pradesh Table 1 reveals that the most dominating families of Angiosperms of Arunachal Pradesh are Orchidaceae (genera 122 spp 545) Legunminosae (genera 67 spp 196) Asteraceae (genera 68 spp 186) Rubiaceae (genera 52 spp 159) Ericaceae (genera 9 spp 158) Poaceae (genera 76 spp 153) Urticaceae including Moraceae (genera 25 spp 129) Rosaceae (genera 18 spp 111) Cyperaceae (genera 22 spp 96) Euphorbiaceae (genera 39 spp 94) Out of all Orchidaceae is the most dominating and fascinating family of the plant with 545 spp is belonging to 122 genera in Aurnachal Pradesh where as 1229 species belong to 184 genera in India So Orchids are often associated as ldquoJewel of Arunachal Pradeshrdquo Out of 545 species 20 species are endemic to the state A large number of primitive

Due to geographical position climatic condition and unique ecosystem it provide high endemism in relatively younger mountain system in the state Out of 17500 species of flowering plants about 5000 species belonging to 140 genera and 47 families are endemic to India There are total 238 endemic species occur in Arunachal Pradesh Some of the endemic species occurring in Arunachal Pradesh are Aconitum lethale Aglaia edulis Albizia arunachalensis Anoectochilus sikkimensis Begonia aborensis Dioscorea wattii Gastrodia arunachalensis Litsea mishmiensis Magnolia griffithii Rhododendron nuttalli R tawangensis Syzygium mishmiense etc

As per utilization of these plants by the tribal people of the state can be categorized as follows (i) Cultivated Plants (ii) Timber Yielding plants (iii) Wild ornamental plants and (iv) Medicinal plants

(i) Cultivated Plants The state is rich in crop plant diversity

mainly on maize barley buckwheat finger millet pea scarlet alliums ginger and different types of fruits etc Cultivated a few vegetable species are Alocasia macrorhiza Amorphophallus bulbifer Cucumis hystrix Monordica cochichinenis Clerodendrum

colebrookianum Piper pedicellatum Vernonia anthelmintica Solanum indicum etc A few fruits species are Abelmoschus manihot Artocarpus chama Citrus assamensis C aurantium C indica C medica Rubus ellipticus Myrica esculenta Musa acuminata Mglauca Mnagensium M Rosacea etc

Spices plant has also tremendous demand in the state as well as in whole country A few spices species cultivated by the tribal people are Allium turberosum Amomum aromaitcum Amomum subulatum Curcuma amada Curcuma Zedoaria Piper longum Piper peepuloides Piper mullesua etc

Timber yielding plants The economy of the state depends upon

the timber plant of the state The timber of this state had great demand throughout the country The bamboo canes also play an important role in the economy of the people of the state A few important timber yielding plant are Actinodaphne obovata Albizia lucida Alostonia schlaris Artocarpus lacucha Biscofia javanica Bombax ceiba Cinnamommum glaucescens Dipterocarpus retusus Gynocardia odorata Kydia calycina Pinus roxburghii Quercus griffithii etc A few common bamboo species are Bambusa pallida Bambusa tulda Dendrocalamus hamiltoni Dendrocalamus strictus Melocanna baccifera etc Another a few cane species are Calamus flagellum Calamus floribundus Calamus latifolius etc

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Due to abiotic and biotic factor such as flood landslide earthquakes completion between the different species and forest fire affected the flora of Arunachal Pradesh To conserve the biodiversity Government have formulated law and legislative Act These are (i) Indian Forest Act (ii) the wild life protection Act 1972 (iii) the forest conservation Act 1980 To protect and conserve the natural resources Government setup 9 wild sanctuaries 2 National parks 1 Biosphere reserve and 1 Orchid Sanctuary Presently 9815 sq km as reserve forest 6677 sq km as wild life sanctuary 246823 sq km as National park 51115 sq km as Biosphere reserve and 100 sq km as Orchid sanctuary are protected area of the state Some of important medicinal plant like Coptis teeta Taxus wallichiana Rauvolfia serpentina Ladies slipper orchid (Paphiopedilium species) Aconitum spp Dioscorea deltoidea Picrorhiza kurrooa Swertia chirata etc exported to the other state of India and outside the country But under regulation Act Convention of International Trade in Endangered species of flora and fauna (CITES) the above plants are protected It is important to note that most of endangered species of the state are out side the protected area So Government should take initiative to bring such type of zone under the protected area Awareness among the people is very essential to save the natural resources In this state jhum cultivation is very popular among the tribal people So they exploited some of the endangered plant species due to lack of knowledge on importance of plants Unfortunately large number of plant species disappears from this state So the tribal people of this area should be taken as coordinating effort to create the awareness in the public through Govt and NGOs

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Probably an exact translation of words that come out spontaneously form the heart of a poet is impossible still a creditable effort was taken by Geetika Phukan to translated it to English) Travelogue On the silent street in Salonah tea garden We lost our way Grieving at our grief An old Kachari said ldquoChildren follow your noses There are dreams on the way not reality At the end of the dreams there will be dawnrdquo We realized Looking for flowers is easier Than finding thorns Flowers do not make us feel They feel themselves Thorns do not feel their sharpness They make others feel As travelers We wanted to thank the Old Kachari So halfway through we killed him And left his blood for the vultures and crows The cuckoos loved us for that And finally we reached a land of swords

POEM

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

There are also lots of scopes to evaluation of bioactive constituent from the flora of the state These bioactive constituents may be utilized in future in preparation of drugs amp drugs intermediate chemical industries pharmaceutical industries etc So conservation of the flora is very much essential at any cost It is very

difficult to conservation of flora by only law and order if there is a lack of interaction between the scientific community and ST people of the state So organizing Van Mahotsava World Environment Day workshop and training program with common public is essential for creating awareness among the general public of the state References 1 Arunachal Forest News Vol 19 2001

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Arsenic problem in north-east a future threat

-Dr Oinam Jayalakshmi Devi

Groundwater arsenic contamination and sufferings of people have been reported in 20 countries in different parts of the world The magnitude is considered highest in five Asian countries and the severity is in order of Bangladesh gt India gt Mangolia gt China gt Taiwan The worlds two biggest cases of groundwater arsenic contamination and those that affected the greatest number of people were in Bangladesh and West Bengal (Chowdhury 2000 Saxena et al 2004 Bhatacharya et al 2002) Arsenic is a semimetal or metalloid occurring naturally in the environment and as a by-product of some agricultural and industrial activities It can enter drinking water through the ground or as runoff into surface water sources Industrial effluents also contribute arsenic to water in some areas It is widely thought that naturally occurring arsenic dissolves out of certain rock formations when groundwater

levels drop significantly Surface arsenic-related pollutants enter the groundwater systems by gradually moving with the flow of groundwater from rains melting of snow etc Drinking water especially groundwater is a major source of arsenic for most people In many parts of world including Taiwan Argentina and Chile it is natural contaminant of ground water elsewhere it has leach into drinking water through mining waste (CMAJ 2002)

The health of tens of millions of people world-wide is at risk from drinking arsenic-contaminated well water In most cases this arsenic occurs naturally within the subsurface aquifers rather than being derived from identifiable point sources of pollution The mobilization of arsenic into the aqueous phase is the first crucial step in a process that eventually leads to human arsenicosis Arsenic occurs in four oxidation states As+5 As+3 As0 and As-3 As+5 and As+3 are the most common in nature whereas the As-3 and As+5 are rare

Distribution of arsenic in groundwater in northeastern states

In the North Eastern region of India natural springs and dug wells are the only cost effective and viable means of fulfilling the needs of freshwater for present population High concentration of arsenic (As) in groundwater in the northeastern states of India has become a major cause of concern in recent years As in groundwater has been detected in some parts of Assam Tripura Manipur Nagaland and Arunachal Pradesh In India after West Bengal and the bordering districts of Bangladesh arsenic in groundwater was detected in part of Assam Arunachal Pradesh Manipur Nagaland and Tripura Maximum arsenic content was observed in Jorhat (Titabor Dhakgorah Selenghat and Moriani Block) Dhemaji (Sissiborgoan and Dhemaji Block) Golaghat district (Podumani Block) and Lakhimpur (Boginodi Lakhimpur Block) in Assam West Tripura (Triania Block) Dhalai (Salema Block) and North Tripura (Dharmanagar Block) districts in Tripura Thuobal (Kakching Block) in Manipur and

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

POEM It is our proud privilege to congratulate Mr Kamal Kumar Tanti for receiving the ldquoMunin Borkotoki Literary Awardrdquo for his poetry book Maarangburu Amar Pita and I am taking the opportunity to publish one of his award wining poem ldquoBhraman Kahinirdquo

Probably an exact translation of words that come out spontaneously form the heart of a poet is impossible still a creditable effort was taken by Geetika Phukan to translated it to English) Travelogue On the silent street in Salonah tea garden We lost our way Grieving at our grief An old Kachari said ldquoChildren follow your noses There are dreams on the way not reality At the end of the dreams there will be dawnrdquo We realized Looking for flowers is easier Than finding thorns Flowers do not make us feel They feel themselves Thorns do not feel their sharpness They make others feel As travelers We wanted to thank the Old Kachari So halfway through we killed him And left his blood for the vultures and crows The cuckoos loved us for that And finally we reached a land of swords

POEM

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Dibang valley (Midland) in Arunachal Pradesh The presence of arsenic (As) in groundwater in the north-eastern states of India and its effect on human health has become a serious concern in recent years A long-term environmental planning is essential to blunt the danger from such pollution Chakraborti et al 2003 and 2007 Nickson et al 2005 has been reported that most of the arsenic affected floodplains in Asia are by the side of the rivers that originate in the Himalayas or Tibet Plateau Thus it is considered that Himalayas and surrounding mountains are potential sources of arsenic bearing minerals Because the North-Eastern Hill states are part of the Himalayan mountain range we anticipated finding groundwater arsenic contamination in the Newer Alluvium (Holocene) of the Brahmaputra Barak Surma and Imphal rivers These basins cover parts of all the seven North- Eastern Hill states Arunachal Pradesh Assam MeghalayaTripura Nagaland Manipur and Mizoram (Fig 1)

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Baruah et al (2003) reported a significant variation of As in nature organic matter of North east India and nature of accumulation of As in these substance They concluded that total arsenic content shows an increasing enrichment from east to west of North eastern region of India The concentration of arsenic in ground water exceeds the permissible level (10microgL WHO) in one district out of 9 districts in Manipur (Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district (Singh 2004) Singh 2006 made report that because high arsenic concentration people were suffering from many types of arsenical skin lesions skin cancer and other internal cancer like lung in North eastern region He made report that one district out of 9 districts in Manipur Arsenic concentration was very high and varies between 798-986 microgl in Kakching block area of Thoubal district However latest studies (Chakraborti et al 2007) reported arsenic contamination in groundwater of three districts Imphal west Imphal East and Thoubal exceeding 10 and 50 microgl are quite high

Table 1 indicate that arsenic pollutant in groundwater of northeast states are very high and people may be at risk of consumption of water contaminated by arsenic gt50microgL The adverse impact of As on human health has been documented and

there are now indications that As can also have a negative effect on agricultural production systems Remediation of As contaminated water is therefore critical Arsenic contamination in Northeastern states is possibly mainly geological and the immediate source material for groundwater is likely to be ferric arsenate (with or without ferric arsenite) derived from an alternation product of the mineral arsenopyrite that was geologically transported to the Bengal delta and Assam valley There is a need for integrated research to understand sources release mechanisms mobilization of As in aquifers and the chemistry of arsenic and high arsenic variance in groundwater of Northeastern state

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

FICTION

Consequences of Time Machine

Himangshu Paul (In this short story I have tried to highlight what may happen if a time machine ever invented fall in wrong hands I am also questioning if a time machine will ever be invented) It was 21st May 2299 I was already

getting late for the conference Actually that day was a great day for me as the government had decided to unveil my invention ldquoTHE TIME MACHINErdquo to the public My time machine would enable a person to travel to any point of time in the past or the future just on pressing of a button It could also make one travel to a desired destination The unveiling ceremony was to be held at 7 orsquoclock in the evening I was very excited thinking about the possible reactions of the people Some might be amazed some might be shocked while some might not believe it calling it a hoax or there would be some people who might question its usefulness or its threat to humanity All these thoughts were roaming in my mind not just that day but for the last few days But whatever be the situation I believed that this invention could never go wrong

Recovering from my sea of imagination I hurried for the ceremony Fortunately I reached there just on the nick of time A very tight security arrangement was made by government which was quite obvious for such a important and unique invention Then I saw the large crowd that has gathered to witness the invention As I expected most of the people were curious to know what it was as it was a never-before experience for all of them But there are still some frowned and expressionless faces questioning the whole idea

I proceeded towards the place where my invention was covered behind a curtain The mayor of the city was going to unveil the lsquoMachinersquo which would be followed by my speech In my speech I was going to address the crowd how my machine would enable people to discover all those unresolved

mysteries of past prehistoric age even may be the facts behind the formation of universe Not only that I will outline how it might help to protect our world from future natural calamities future alien attacks etc When commercialized this machine could act as ldquotime travellerrdquo taking people anywhere in anytime These thoughts bring a sense of pride to me from the time I was building the machine and then the moment of glory arrived After the curtains were drawn there was a great applaud and I was asked to deliver the speech As I was just about to speak an unexpected thing happened---the lights went off and there was darkness everywhere Then suddenly there was a loud roaring sound of an engine followed by a bang and a flash of lightning After a few moments lights came but the Time Machine was not there where it was Everybody was confused what had happened but I think I knew that hellip my Time Machinehelliphellip is gone Someone stole it

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

POEM It is our proud privilege to congratulate Mr Kamal Kumar Tanti for receiving the ldquoMunin Borkotoki Literary Awardrdquo for his poetry book Maarangburu Amar Pita and I am taking the opportunity to publish one of his award wining poem ldquoBhraman Kahinirdquo

Probably an exact translation of words that come out spontaneously form the heart of a poet is impossible still a creditable effort was taken by Geetika Phukan to translated it to English) Travelogue On the silent street in Salonah tea garden We lost our way Grieving at our grief An old Kachari said ldquoChildren follow your noses There are dreams on the way not reality At the end of the dreams there will be dawnrdquo We realized Looking for flowers is easier Than finding thorns Flowers do not make us feel They feel themselves Thorns do not feel their sharpness They make others feel As travelers We wanted to thank the Old Kachari So halfway through we killed him And left his blood for the vultures and crows The cuckoos loved us for that And finally we reached a land of swords

POEM

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

There was no clue whatsoever for few days of my lsquoTime Machinersquo Then suddenly one day the local police station received a report that identical people were seen in the suburb region of the city At first the police gave no notice as identical twins were common but soon it was found out that the number of identical persons increased upto 10 or 12 This time the cops got alarmed and decided to visit the place On first look it seemed a deserted factory having barely a soul But on closer inspection it was found out that the factory had been occupied by no less than thousand soldiers and though they (cops) were not sure each soldier seemed to be equipped with highly sophisticated weapons And there one of the officers peeping through an opening in the wall of the factory saw the lsquoTime Machinersquo heavily guarded by the soldiers The police decided not to fight with handful officers but to return with a greater army

When the police related the story to me I was happy as well as frightened Happy for I have found my machine at last and frightened for I have to fight an army much larger and stronger than the police itself to

get it Nonetheless I decided to go with them to get my machine back The next morning I along with an army of about thousand cops marched towards their hideout As we reached there we warned them to surrender or else they will be killed There was silence for a moment but soon the marching of the soldiers could be heard In the next moment there were soldiers in front of us and as doubted equipped with sophisticated weapons But they were not there to surrender but to fight and they were not thousands but millions They were led by a man whom I seemed to know He was none but one of my rival scientists They attacked us The copsrsquo weapons seemed toys before theirs In an instant the whole army of ours was destroyed I could just mange to flee from there

I told the government about the incident The government decided to take measures to cope with the situation A tight security was provided to me but there was something that was still disturbing me In the comfort of my home I reanalyzed the whole situation------- as observed the army of millions had identical soldiers It seemed as if he has turned a few soldiers into million copies of themselves Has he cloned them No it couldnrsquot be because cloning is a lengthy process and in this case only the previous day the cops observed only thousand soldiers and now they are million How come such fast copying could be done In the back of my mind I knew that all these things are somehow related to my time machine

After a long thought I came to the conclusion that he brought advanced weapons from the future But copying oneself to such a large scale was still a great mystery Then suddenly an idea strokes me This building of large army in a short time can be had if we play with the time It could have happened that he has brought himself or a few of his best soldiers to the present time from a certain time in the past using my time machine He again went back to an earlier time and brought them again Doing it again and again each time going to a time earlier than before he created an army for

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

himself consisting of his best soldiers This process might not be fast but time is not a factor with my Time Machine as he could arrive just at any moment he desires He could even immortalize himself as he could build an army of himselves by bringing himself from different point of time Thus the cause of calamity is known and I feel that the criminal is not him but me as I was the creator of destructive Time Machine

The present owner of the Time Machine was gradually becoming a threat to the world His army was getting larger and larger The entire police force was unable to stop him Being the creator of the calamity the moral responsibility to stop him was vested upon me The only thing that could help me to fight him was another Time Machine If I kill him he could be brought again from an earlier time The only way to kill him once and for all was by killing him just before his birth This would require another Time Machine to go to the past and kill his mother before his birth It was a risk as it could again fall into wrong hands but I had to take the gamble Immediately I started working on it After much hardship as the work was proceeding towards completion another unexpected misfortune happened Somehow the villain came to know about my plan and it seemed as if he was all prepared for this

He decided to give me a taste of my own medicine Before I could complete my Machine he went to the past and killed my grandfather in his childhood But he could not understand till late that this act of him has started an infinite space-time cycle which swallowed everyone including me and him The space-time cycle started as soon as he killed my grandpa and helliphellip helliphellip ldquoThe death of my grandfather meant that my father and subsequently I were not born As I was not born the time machine has never been invented which meant that Time Travel was not possible yet and this prevented my rival scientist to go to the past to kill my grandfather That means my grandpa was alive and so do I As I was born I grew up to build the Time Machine which he stole and used to do all the

misdeeds including the one ndashgoing to the past to kill my grandfather and thus this cycle continuesrdquo

I think God has punished me for building such a destructive invention and for my dauntlessness to mess with the space-time cycle and to play with the laws of nature As a consequence I have been left trapped in this cycle in which I am getting vanished and materializing every couple of seconds and there is least hope that I could recover from herehelliphellip Could you helliphelp me out

POEM It is our proud privilege to congratulate Mr Kamal Kumar Tanti for receiving the ldquoMunin Borkotoki Literary Awardrdquo for his poetry book Maarangburu Amar Pita and I am taking the opportunity to publish one of his award wining poem ldquoBhraman Kahinirdquo

Probably an exact translation of words that come out spontaneously form the heart of a poet is impossible still a creditable effort was taken by Geetika Phukan to translated it to English) Travelogue On the silent street in Salonah tea garden We lost our way Grieving at our grief An old Kachari said ldquoChildren follow your noses There are dreams on the way not reality At the end of the dreams there will be dawnrdquo We realized Looking for flowers is easier Than finding thorns Flowers do not make us feel They feel themselves Thorns do not feel their sharpness They make others feel As travelers We wanted to thank the Old Kachari So halfway through we killed him And left his blood for the vultures and crows The cuckoos loved us for that And finally we reached a land of swords

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

compound

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

POEM It is our proud privilege to congratulate Mr Kamal Kumar Tanti for receiving the ldquoMunin Borkotoki Literary Awardrdquo for his poetry book Maarangburu Amar Pita and I am taking the opportunity to publish one of his award wining poem ldquoBhraman Kahinirdquo

Probably an exact translation of words that come out spontaneously form the heart of a poet is impossible still a creditable effort was taken by Geetika Phukan to translated it to English) Travelogue On the silent street in Salonah tea garden We lost our way Grieving at our grief An old Kachari said ldquoChildren follow your noses There are dreams on the way not reality At the end of the dreams there will be dawnrdquo We realized Looking for flowers is easier Than finding thorns Flowers do not make us feel They feel themselves Thorns do not feel their sharpness They make others feel As travelers We wanted to thank the Old Kachari So halfway through we killed him And left his blood for the vultures and crows The cuckoos loved us for that And finally we reached a land of swords

ldquoIn science one tries to tell people in such a way as to be understood by everyone something that no one ever knew before But in poetry its the exact oppositerdquo

POEM

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

Do you know

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

POEM

Slums Dwellers Dr Manabendra Pathak

(Inspired by the movie Slumdog millionaire) In a city of dream and destiny of millions I discovered a strange place and a stranger He asked me how much time is required To count the numbers from one to two millions I could nt answer He asked me Is there a more secured shelter than the sky I could nt understand him He asked me Is there any drug that may cure hunger I was numb He asked Do you have the guts in listening to my song A song of paradisehellip Without delay I left the place As I missed all the questions I was out of the race of becoming a Millionairehellip The poet Dr Manabendra Pathak is presently working as a Post-doctorale Fellow in Technion-Israel Institute of Technology Israel

There is a prize which is just opposite (rather parody) to actual Nobel Prize The Ig Nobel Prizes which is also given each year in early October for ten achievements

that First make people laugh and then make them think The prize is organized by the scientific humour magazine ldquoAnnals of Improbable Researchrdquo (AIR) and are normally presented by genuine Nobel Laureates at a ceremony at Harvard Universitys Sanders Theatre and then they give public lectures at MIT The first Ig Nobels were awarded in 1991 for the discoveries That cannot or should not be reproduced

Fig The Ig Nobels a festival of daftness

The 2008 Ig Nobel Prizes were awarded on 2nd October at the 18th First Annual Ig Nobel Prize ceremony The winners of 2008 are listed below Nutrition Prize awarded to Massimiliano Zampini of the University of Trento Italy and Charles Spence of Oxford University UK for their study showing that food actually taste better if it sounds crunchier They electronically modified the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is Peace Prize Received by The Swiss Federal Ethics Committee on Non-Human Biotechnology (ECNH) and the citizens of Switzerland for adopting the legal principle that plants have dignity

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Ancient History of NorthEast India at Mahabharat

The earliest references to Manipur date back to the ancient Indian epic Mahabharata in which several characters such as Chitrāngadā Ulupi Babruvahana and Iravan are Manipuris

Chitrāngadā daughter of the king of Manipur married Arjuna and Babrubahana was born to the couple

Ulupi was one of Arjunas wives She was the mother of Iravan

Iravan fought on the side of the Pandavas in the Kurukshetra war and was killed by the Rakshasa Alumvusha on the eighth day of the war

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3

Uncatalysed Michael addition of indoles Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent-free conditions

Synthesis of some novel 3-alkylated indoles via a three-component reaction in solvent free conditions The reaction which gave access to an important class of novel indole (or 5-alkylated barbituric acid) derivatives in good to excellent yields also demonstrates an uncatalysed Michael addition of indoles to αβ-unsaturated systems viz αβ -unsaturated cyclic β-diamides (Scheme 5) Chapter 3 Section A

An efficient and clean synthesis of bis(indolyl)methanes in a protic solvent at room temperature

Both solvents had their own advantages in terms of the reaction simplicity time required

easy work-up procedure and overall yields The reactivity increased with the increasing order of

acidity of the solvents (H2OgtCH3OH) Moreover the reaction was highly chemoselective and

applicable only to aldehydes and not to ketones containing both the functional groups in a same

compound

Chapter 3 Section B

A novel and efficient method for the synthesis of unsymmetrical diindolylmethanes and indolyl-heterocyclic alkanes

Symmetrical diindolylalkanes can be readily synthesized by Lewis or protic acid catalyzed indole-aldehyde condensation reactions but synthesis of unsymmetrical DIMs is still highly demanding in synthetic community There are very few reports on the synthesis of unsymmetrical DIM and all of them have a number of drawbacks and limitations

It was very interesting to note that the addition of a few drops of water to the reaction mixture accelerates reaction considerably with improved yields Chapter 4 Section A

A facile synthesis of 612-disubstituted 57-dihydroindolo[23-b]carbazoles from the reaction of indole and aldehyde catalysed by molecular iodine

In the reaction strategy utilizing equimolar amounts of indole 1 and bezaldehyde 2a in the presence of catalytic amount of molecular iodine (2 mol ) in refluxing acetonitrile afforded 612-diphenyl-57-dihydroindolo[23-b]carbazole 3a in excellent yields (Scheme 8) The product was isolated simply by filtration and recrystallized from a mixture of DMF and CHCl3
