The biennial conferences of the Society for Underwater Technology have achieved an excellent reputation for the quality of their presentations, which cover topics of the most acute current interest, as well as those at the forefront of review and development. The 1994 conference on Subsea Control and Data Acquisition formed no exception, since it covers subjects at the cutting edge of modern technology. It is a matter of increasing concern that products are becoming overspecified, resulting in excessive costs and longer development schedules, while not conferring an equivalent benefit in...

The 29 presentations from the April 1989 Institute are organized within eight sections covering methods, theory, applications of STM at solid state surfaces, liquid-solid interface, applications of STM at organic and biological materials, electron and ion point sources, force microscopy, and optical

One of the major challenges of science in the last few years of the second millennium is learning how to design materials which can fulfill specific tasks. Ambitious as it may be, the possibilities of success are not ne li ble provided that all the different expertises merge to overcome the limits of eXIsting disciplines and forming new paradigms science. The NATO Advanced Research Workshop on "Magnetic Molecular Materials" was organized with the above considerations in mind in order to determine which are the most appropriate synthetic strategies, experimental techniques of investigation,...

Begins a series publishing courses and educational seminars organized by the Commission of European Communities' Joint Research Centre at Ispra, Italy. Perhaps as the series matures, responsible parties will see the wisdom of not trusting authors to present readable typescripts, of mentioning where

The focus of the 22nd Annual Detroit Cancer Symposium was the presentation and discussion of cytotoxic agents, with a significant portion of the symposium including the exciting frontiers of drug discovery being explored by the National Cooperative Drug Discovery Groups (NCDDG) Program. The symposium brought together a large number of investigators from government, universities and pharmaceutical companies involved in the discovery and development of new anticancer agents. Exciting new leads were presented and the status of others presently under development was discussed.
Of particular...

Small and large telescopes are being installed all around the world. Astronomers have thus acquired better access to more modern equipment; not in the least to photometers, which are very important tools for the contemporary observer. This development of higher quality and more sensitive equipment makes it very necessary to improve the accuracy of the measurements. This guide helps the astronomer and astronomy student to improve the quality of their photometric measurements and to extract a maximum of information from their observations. The book is based on the authors' observing experience,...
