Oral presentations content

To prepare overhead transparencies for oral presentations, you can use spirit-based markers and acetate sheets. An alternative approach is to print directly from a computer-based package, using a laser printer and special acetates, or directly to 35 mm slides. You can also photocopy on to special acetates. The use of Microsoft PowerPoint as a presentation package has become more important in recent years. It is not uncommon to find a computer and presenter available for student use. Advice on content and presentation is given on p. 344. 

The importance of finding the right balance between quality of the form and of the content cannot be stressed enough, in addition to the requirement that the contents should be carefully tuned to the intended target audience. We all reahze however, that this equally applies to reports, posters, and oral presentation. 

In addition to the 19 main papers, two short papers and nine posters (preceded by short oral presentations) were featured at the Seminar. Nine of these eleven short communications are summarized in the form of abstracts on pages 261-286. The titles of these communications are listed in the Table of Contents. Abstracts of two communications are not included that of D. Valentine, Jr. (Catalytica Associates, Inc.) on phosphines having both chiral phosphorus and chiral ligands has been published in... 

The contents of the current volume presents a sampling of more than 150 oral and poster papers delivered at the Symposium on Access in Nanoporous Materials II held in Banff, Alberta on May 25-28, 2000. The selected papers cover the three main themes of the symposium (i) synthesis of mesoporous silicas, framework-modified mesoporous silicas, and surface-modified mesoporous silicas, (ii) synthesis of other nanoporous and nanostructured materials, and (iii) characterization and applications of nanoporous materials. About 70% of the papers are devoted to the synthesis of siliceous mesoporous molecular sieves, their modification, characterization and applications, which represent the current research trend in nanoporous materials. The remaining contributions provide some indications on the future developments in the area of non-siliceous molecular sieves and related materials. Although the present book does not cover all topics in the area of nanoporous materials, it reflects the current trends and advances in this area, which will certainly attract the attention of materials chemists in the 21st Century. 

Human volunteers who drank wine containing inorganic arsenic excreted methylarsonic and cacodylic acids in their urine (96). These two compounds also occur in the urine of copper smelters, the elevated arsenic content presumably coming from copper ores (97). Cacodylate ion forms when H34As04 is administered orally to dogs or hamsters (98-100). A Japanese group reported that various small animals will form methylar-sonate and cacodylate from H3ASO4 (101). On the basis of presently available data, it remains uncertain whether arsenic biomethylation occurs from the bodily processes of the mammals themselves or from microflora of the intestinal tract.
