Slide 2 The perfect presentation .or maybe not!!! Slide 3 Choose a background that doesnt distract and makes it easy to see the text Choose a background that doesnt distract and makes it easy to see the text Slide 4 I said, choose a background that doesnt distract and makes it easy to see the text choose a background that doesnt distract and makes it easy to see the text Slide 5 Either change the font colour Slide 6 Or, change the background Slide 7 Or make the whole thing simpler. Light coloured fonts on a dark background are easily read even at small sizes like 20 point Slide 8 Or, use a light background which allows the use of various dark coloured fonts which are easily read even at small sizes like 20 point Slide 9 Thats why are EXIT signs green on black? Or red on white? Or white on green? Slide 10 OK, now add a logo which gives your organisation some free advertising maybe not so big! Slide 11 Thats better! Now we can concentrate on you and your presentation Slide 12 Use a font style (eg Arial) which is appropriate. Scientific type presentations dont go well with some styles which are more suited to advertising agencies Slide 13 One of the most destracting things for the audience is poor speling. There is no exuse for this since your spelcheker should allert you in most cases. Slide 14 Proof reed your slides carefully or, better still, have someone else check your presenation to avoid pubic humiliation. Slide 15 By the way. To maintain your professional credibility, make sure you use the correct word, eg Complimentary or complementary practise or practice affect or effect Slide 16 If you use animations These can assist In emphasising a point But dont overdo it! Because it becomes distracting Or the message Will be lost in the technology Got that? Slide 17 Illustrations help to maintain interest but dont make them too small otherwise the audience wont get the message Slide 18 Greater impact is achieved by good pictures Kalgoorlie Super pit Union Reefs Tailings Dam Kaltails tailings dam Slide 19 Your presentation will be out of this world! Hubble image of comet impact on Jupiter Hubble photo looking back 15 billion years Slide 20 Why bother putting in information which cannot be read easily? All you can do is apologise! Slide 21 By all means, use images scanned from other sources but note that the quality may not be all that great. Slide 22 It doesnt take much work to generate a legible table.

Slide 24 General trends are what you are aiming to show Slide 25 This may be OK for a specialist audience. Slide 26 This may be just a little too hard to read!!! Slide 27 But this may be more appropriate for a general audience Slide 28 This is a presentation not a publication!! Keep the mathematics simple. Developing a Systematic Heat Balance Model Enthalpy balance around any process unit: where molar enthalpies are defined thus: and where molar heat capacities typically take the following form: where a, b, c, and d are empirical constants. Upon integration: Slide 29 And things like this should never be seen! (but they have been) Slide 30 Develop your argument gradually. One concept at a time is good. For irreversible reactions involving a limiting reactant: Reversible reactions (e.g. precipitation reactions) are much trickier Subject to thermodynamic constraints Best solved iteratively Slide 31 Final summary should be brief. The following will take too much time. The fine material has a slower relative leach rate than the coarser particles The overall leach rate is a domain diffusion control The leach domain is determined by the retained moisture determined by the fines The model developed describes the leach rate changes well The model functional form is the same when developed from two approaches Any leach model must take into account the poorer relative leaching of the fine material Without progressive data care needs to be taken in applying the analysis technique Further work is needed to identify a normalisation technique to allow comparison between various top sizes Blah, blah, blah! Slide 32 And dont forget your acknowledgments My thanks to my colleagues who have provided the source material for much of this presentation. In order to avoid embarrassing them, no names will be mentioned.
