Abstract
Integrating electronic devices with unconventional substrate has been a popular research direction. Among these substrates,cellulose fiber paper has advantages in low-cost, recyclable and bio-degradable. We demonstrated directing printing of all contactelectrodes on standard untreated Fuji Xerox printer paper without using planarization layer. The screen-printed gate electrodesbased on silver nanoparticles can smooth out the paper substrate surface by two orders of magnitude and allow us to useparylene and DNTT as the dielectric and active layer directly. The transistors show average mobility of 0.297 cm 2 V-1 s-1 andon/off ratio larger than 105. The low leakage current allows us to demonstrate memory properties by employing the floated gatemethod. The devices show excellent memory retention time for more than 10,000 s. The unique flexibility and combustibility ofthe organic transistors on paper substrate manifest their applications as next generation of green electronics. © 2013 ElsevierB.V. All rights reserved.

Abstract
The concept of biodegradable plastics, i.e. biologically degradable materials, appears to be a possible solution for an evergrowing production of plastic wastes as the biodegradable plastics shall have a substantially lower environmental impact and beable to at least partially substitute the production of plastics from oil derivatives. Currently, a promising direction seems to be thedevelopment of a polymer on the base of lactic acid, called polylactic acid (PLA). Packaging made from the material, mainlydrinks bottles, could be used on a mass basis in future. Such generated waste will have to be recycled, which shall bringproblems connected with separation of biodegradable material from common plastics. This paper deals with the issue ofseparation of PLA from PET (polyethylene terephthalate). Mixing the above mentioned plastics in the recycling process leads totheir devaluation. Due to the occurrence of PLA material the quality of the feedstock decreases during recycling PET bottles. Thecurrently implemented research at the Institute of Environmental Engineering of Mining Faculty - Technical University of Ostravaexamines the possibilities of separating the two materials by means of flotation. This method has brought a partial success, moreeffective results are expected after its optimization.

Abstract
Biosorption of Cd(II) ions from aqueous solutions has been studied and determined to adsorption capacity. The experimental dataobtained from batch equilibrium tests have been analyzed by three two-parameter (Freundlich, Langmuir and Temkin) isothermmodels, four three-parameter (Redlich-Peterson, Sips, Toth and Khan) isotherm models and kinetic models including thepseudo-first order and pseudo-second order. The adsorption data fit well with Temkin isotherm for orange peel and Freundlichisotherm for walnut and hazelnut shell. Maximum experimental adsorption capacity was found to be 13.947, 8.57 and 8.847 mg/gfor orange peel, walnut shell and hazelnut shell, respectively. Experimental kinetics data was well-fitted for pseudo-second orderfor all adsorbents and correlation coefficient for kinetics was above 90%. © SGEM2011 All Rights Reserved by the InternationalMultidisciplinary Scientific GeoConference SGEM.

AbstractMaterial transportation by belt conveyers is widely used in many industrial branches including mining plants. Belt conveyingdevelopment during the last year was oriented mainly on construction of belts. The consequence of this is the improvement of itsmanufacture qualities bringing down the costs for their exchange and maintenance.Despite the fact that there are sometheoretical calculations based on a standards it is common in the industry that the belt is not properly selected or it isoverdesigned or number of its types is too large what can lead to increased costs for its storage. The paper describes theoptimization of number of belt types in mining company SIDERIT, s. r. o. Nižná Slaná by the method of modernization andunification of belts under practical skills and projecting based on theoretical calculations.

AbstractMain obstacle using of fly ashes in building, that is its main consumer, is the residue of unburned coal; it is expressed of loss onignition - LOI. In present, the valid STN and EU standard limits the content of LOI to 3 - 5 %, in national conditions maximum 7 %.Application of processing technologies also has to assure utilization of fly ash that provides a possibility of complex utilization ofindividual products obtained by modification. By means of corona separation, based on different conductivity of individual fly ashelements, it is possible to separate unburned coal particles. The fly ash sample from black coal burning in melting boiler that wasdeposited on fly ash deposit, content of LOI of dielectric particle 6,45 % at 61 % weight yield was achieved. In the samples takenfrom dry taking of fly ash the non-conducting product contained 7,72 % of LOI at 73 % of weight yield.

Abstract
The theme of this article is concerned with the utilization of waste from grey cellular concrete production. This waste is crushedby swing-hammer mill and the final waste product is sanitary crushed material with grain size of 0.5 - 2 mm. This crushedmaterial was tested for sorption and neutralizing capacity. The results obtained were compared to those sorbents currently usedin practice. It has been shown that the new sorbent achieves the same level, in some cases higher, as usual sorbents. ©SGEM2013 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

Abstract
Electrokinetic potential (zeta potential) is a characteristic parameter for description of the surface chemistry of solid flat materialsand it can be used for a fast analysis of materials modified by different chemical or physical methods. Due to its sensitivity, zetapotential is able to distinguish surface modified by coating with monolayers of various materials or nanostructures created afterplasma treatment. Also metal nanostructures deposited on surfaces can be characterized by zeta potential. It can also be usedfor isoelectric point determination of materials. We present data on zeta potential in 0.001 mol/dm3 KCl at constant pH≈7.0 andalso in pH range (2.5-7.0) for isoelectric point determination for pristine polymers PET, PTFE, PS, LDPE, HDPE, PLLA, PVF,PVDF, PMP and polyimides (Upilex R, Upilex S, Kapton). The zeta potential of selected polymers, modified by plasma and bychemical coatings (e.g. by biphenyldithiol or polyethyleneglycol) or by gold deposition was measured too. Zeta potentials of thesemodified materials were also studied to confirmation that electrokinetic analysis is acceptable method for their fast description. ©(2013) Trans Tech Publications, Switzerland.

Abstract
The technology of the underground coal gasification (UCG) is still under development and provides alternative for conventionalunderground mining. UCG is the process, which can be attractive from environmental and economic aspect and is able to have awide utilization in the future. This technology is less expensive than conventional mining. For research and good analyze of thisprocess there was created the physical model of the gasifier, that simulate the conditions of the real coal-bed in geometricsimilarity. On created physical model was performed a several experiments represent a various underground conditions. In thegasification process the input is the coal (coal-bed) and oxidizer (mixture of the air and oxygen), which suitable combinationprovides the best conditions for gasification. One of the expected outputs from the coal gasification process is the hightemperature in the coal-bed, which enable running of the chemical reaction needed for the syngas generation. The control of thistemperature in the single places of the coal-bed would enable to control behavior of the chemical reactions so the burning queueproceeds. The measurement of the temperatures inside the coal-bed is still complicated because there is the high thermocouplesmortality in aggressively hot environment. For this reason is needed to use mathematic -physical apparatus for indirectmeasurement of these temperatures. In this contribution is presented proposal of the indirect temperature measurement structurein the coal-bed that was verified in the laboratory conditions on the experimental gasifier. © 2013 IEEE.

AbstractThis paper presents the situation of coal mining in Slovakia, focusing on the social-political aspects and environmental aspects ofits sustainable development. In recent years, the mining of lignite and brown coal in Slovakia has been closely linked to theproduction of electricity and heat in the Novaky power plant. Domestic brown coal production covered more than three quarters ofdemand in the Slovak Republic in the last few years. The sustainability of coal mining in the coming years in Slovakia is closelyassociated with raw materials reserves, new mining technologies, the development of the Novaky power plant, and thegovernment's commitments to national economic interests through securing the energy supply or state aid. Of course, of thesefactors must be considered in the context of international obligations, such as those related to climate and environment,particularly air protection. The three most important Slovak brown coal deposits are located in the Upper Nitra Basin. Thisterritory includes areas in the 5 th and 4 th degrees of environmental quality, signifying a disturbed and very disturbedenvironment. Since coal is expected to remain the dominant fuel for electricity generation araund the world, and in particular formany of the countries of Central and Eastern Europe, it is necessary to create conditions for the environmental sustainability ofcoal mining in the coming years within the context of international obligations. Both the security and the stability of the electricitynetwork in Slovakia and maintaining employment levels in the Upper Nitra region play important roles in this discussion.Underground coal gasification (UCG) is a newmining technology and a technology for gas recovery in situ. A comprehensiveevaluation of the impacts of underground coal gasification was carried out in addition to summarization of the expected impacts interms of the significance and distribution of the time period. Based on a comprehensive assessment of the proposed action, itcan be stated that it could bring a socially unacceptable risk to the area, specifically the significant impairment of health or theenvironment (groundwater and nearby hot springs in Bojnice). The implementation of operations could affect the population'shealth, since the partition is placed in close proximity to residential areas.

Abstract
Main focus of this study was on characterization of surface properties of virgin and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine(DPPC) phospholipid layer coated poly(ethylene terephthalate) (PET) and polycarbonate (PC) planar articles. Surface propertieswere followed measuring static contact angles of wetting by means of sessile drop method and deposition of negativepolystyrene (PS) colloidal particles followed by impinging jet method at defined flow regimes. It was found that phospholipidcoating of both studied samples (PET, PC) let to the vigorous increase of the surface free energy. For coated samples major partof the surface free energy was dominated by polar component in contrast to the non-treated materials. Here the dispersivecomponent was dominating. Results of the deposition experiments of polystyrene particles of 3 µm diameter correspond withtrends obtained by contact angle measurements, i.e. the surface treated materials exhibited higher surface activity reflected inincreased particle deposition rates. Simultaneously there was confirmed the fact, that with increasing magnitude of the Reynoldsnumber of the dispersion flux the higher deposition rates were observed. © 2011 Elsevier Ltd.

Abstract
In this paper analog input/output signals are used to control laboratory froth flotation machine using industrial panel PC. Dataacquisition is provided by two Advantech PCI cards, while flotation control is based on connection of adjustable frequency drivefurther connected to AC motor for agitation control, mass flow controller for air flow control, pH and temperature transmitters withaccording probes for pH and temperature logging respectively. Process control is provided by graphical user interfaceprogrammed in MATLAB. This practical engineering design allows researchers to set parameter values prior to flotation test aswell as log and save measured values for further processing.

Abstract
Apart from a high concentration of iron, mine water can also contain a higher concentration of manganese. Extraordinarily highconcentrations can be found in acid waters from the surroundings of ore deposits, e.g. the water from the sulfitic ore deposits inSmolník contain up to 40 mg.l-1 of manganese. The legislation ordains discharge of water into surface water with a maximumconcentration of manganese of 1 mg.l-1, and therefore it is vital to reduce the content of manganese in the mine water to apermissible value. Within the research work, a variety of demanganization methods were tested. In conclusion of the paper, so farmost optimal method of manganese removal from acid mine water is suggested.
