Chemical search image

Specific chemical search image (Melcer and Chiszar, 1989). They learn a mouse s chemosensory signature, which is independent of envenomation, and follow its scent trail (Chiszar 1990).

The search for Turing patterns led to the introduction of several new types of chemical reactor for studying reaction-diffusion events in feedback systems. Coupled with huge advances in imaging and data analysis capabilities, it is now possible to make detailed quantitative measurements on complex spatiotemporal behaviour. A few of the reactor configurations of interest will be mentioned here. 

GORE. The CORE Electronic Chemistry Library is a joint project of Cornell University, OCLC (On-line Computer Library Center), Bell Communications Research (Bellcore), and the American Chemical Society. The CORE database will contain the full text of American Chemical Society Journals from 1980, associated information from Chemical Abstracts Service, and selected reference texts. It will provide machine-readable text that can be searched and displayed, graphical representations of equations and figures, and full-page document images. The project will examine the performance obtained by the use of a traditional printed index as compared with a hypertext system (SUPERBOOK) and a document retrieval system (Pixlook) (6,116). 

ITPAIS, the Image Technology Patent Information System was developed between 1975—1985 by Eastman Kodak Co., Agfa-Gevaert (Antwerp/Leverkusen), and Fuji Photo Film Co., Ltd., and encompasses selected patents and Hterature references related principally to the chemical aspects of image technology. Search terms used for this table were the same as in the previous edition, and the Derwent patent database was used for the search data presented here. 

Theory must play a role in addressing the data storage and search problems associated with the increasingly large datasets generated by chemical imaging techniques. 

One of the main challenges for risk assessors and managers is to make people aware that our knowledge on chemicals is incomplete and uncertainty is inherent to the risk assessment process, especially if mixtures are involved. This is a difficult task since the notion of uncertainty is in conflict with the traditional image of the natural sciences as a provider of unambiguous answers. Not only the general public suffers from this view, but also administrators and policy makers, who often consider uncertainty a nuisance in their search for clear answers and effective policy actions. Here lies an important task for risk assessors and communicators, that is, the development of adequate tools to identify, describe, quantify, and communicate...
