What are the important trends in catalysis for the future?

(x) C 1 chemistry: Methane activation (oxidative coupling to ethylene, direct oxidation to methanol and/or formaldehyde) ; syntheses from CO and H2 (e.g. higher alcohols, C2 oxygenates). Alkane activation (e.g. dehydrogenation to alkenes, ammoxidation of propane, controlled oxidation and oxychlorination of ethane) . Highly selective syntheses in the field of fine chemistry. Regarding the topics of environmental protection; Catalysts for the abatement of pollutants from motor vehicles. More selective catalysts designed to reduce the emission of polluting effluents from industrial processes. Catalysts for alternative syntheses from less harmful feedstocks (or intermediates), particularly where the present technology involves the use of hazardous reactants for the environment or for the human beings. Catalysts for the desulphurisation of liquid hydrocarbon fractions. Catalytic methods aimed at the elimination of pollutants in the flue gases (e.g. DeNOx for gas turbines, incinerators, boilers and Diesel engines, combined DeNOx and DeSOx, hot desulphurisation) . Catalytic combustion for power applications, aimed at reducing the NOx emissions. Catalysts for reformulated gasolines. For each topic you choose to focus on (ideally two or more) : (a) what is the objective and the potential impact? (b) What progress should be made? (c) How realistic is the objective? (d) Is it related to other fields of catalysis? (e) If so, how could progress in the other fields help the objective?

Ventilation

Welcome to the 'Blue Pages'. This is where the Editorial Advisory Panel for Building Services Engineering Research and Technology publishes state-of-the-art articles on developments in building services engineering practice and research. The articles are very short, on one theme of current interest, and are edited by a guest editor rather than going through the longer refereeing process for conventional research papers. This is to encourage consultants and contractors to discuss their latest developments in a non-commercial manner. Academics will also be asked to outline current research areas in universities and colleges. Without the constraint of full refereeing there is scope in the articles to provoke interest and to raise issues for discussion. Consequently the Editor of BSER&T is happy to receive and publish letters furthering the discussion of 'Blue Pages' articles. If you have a suggestion for an article or topic you would like to see included in the 'Blue Pages' please inform the Editor, Barry Copping. Comments on the 'Blue Pages' are also welcome. 'Blue Pages' will only succeed if readers of the journal wish the feature to succeed and contribute to its success.

General and Specific Influences on the Extension of Learning: Some Suggestions from Recent Cognitive Psychology

Consider the following pattern of events in special education teaching. You have identified a four-step procedure that is important for the current topic you are working on with your students. The topic might be in a curriculum area like mathematics or in a behavioural area such as social skills. You devise and carry out a series of lessons on this topic and, after a suitable period of practice, you are pleased to observe that the steps in the procedure are used successfully by most of the group. The procedure is also used on the day following the original teaching, when you reinstate the training situation and conditions: Many of the students produce the procedure without prompting! The next day you test to see whether the students will use the procedure in a situation which involves a modification to the conditions you used in the original training. You might change the format of the mathematics problem or the social situation. For many of the students it seems as though your teaching in the use of the procedure never occurred. They act as though the procedure no longer exists. They do remember it when you remind them of the original training situation, but they don’t do that unless you provide the reminder. They have learned the procedure but they can’t transfer that learning.

The scheme of things

I decided to begin my tenure on this column by describing two recent proposals for additions to Scheme. The first is a facility for creating new, programmer-defined da ta types; the second makes it possible for procedures to return more than one value. These proposals will be considered by the Scheme authors for inclusion in the Revised 5 Report on Scheme whenever that document comes up for discussion. For future columns, I am considering discussing other possible directions for Scheme language development, inc luding macros, dynamic binding, exception handling, modules, and concurrency. I may also do a column or two on Scheme compilation and interpretat ion techniques. If you've got an idea for some other topic you'd like me to discuss here, please feel free to write me at the addresses above; your suggestions are always welcome.

Handbook of technical writing

New this edition: Up-to-date information on on-line research and computer resources. A unique four-way access system enables users of the Handbook of Technical to find what they need quickly and get on with the job of writing: 1. The hundreds of entries in the body of the Handbook are alphabetically arranged, so you can flip right the topic at hand. Words and phrases in bold type provide cross-references related entries. 2. The topical key groups alphabetical entries and page numbers under broader topic categories. This topical table of contents allows you check broader subject areas for the specific topic you need. 3. The checklist of the writing process summarizes the opening essay on Five Steps Successful Writing in checklist form with page references related topics, making it easy use the Handbook as a writing text. 4. The comprehensive index provides an exhaustive listing of related and commonly confused topics, so you can easily locate information even when you don't know the exact term you're looking for.

A Criminologist Looks at Social Work

THE topic you are to consider at this Conference — the dependence of any single specialty of social work upon the other branches of the field — implies that there is not at present sufficient integration between the various activities of social workers and that greater interplay is desirable. Of course, differences in techniques and aims need not necessarily be an unmitigated evil. On the contrary, in a developing profession a rich variety of points of view and methods is to be desired. But a greater degree of collaboration and comparison of notes is, I take it, one of the aims of your discussions about the interrelationship of the different branches of social work.
