Operational Computer-Based Systems At The Chemical Abstracts Service

The American Chemical Society (ACS) is a non-profit organization chartered by Congress as a scientific and educational organization. The Chemical Abstracts Service (CAS) is a division of the American Chemical Society. Like any society the ACS is concerned with helping its members to get their papers published and to help chemists and chemical engineers to gain recognition in the scientific and general public communities. Equally important, however, the ACS wants to have available information put to use. To this end, it is concerned that all forms of research, development, and applied technology be fully recorded, indexed, and retrievable for the full scientific community. Chemical information is not used only by chemists and chemical engineers. It is used by many other kinds of scientists. In line then with the major purpose of getting available information put to use, it is clear that the ACS operates the Chemical Abstracts Service not only for the benefit of members of the Society, but for a broader reason. We want chemical and chemical engineering information put to use in the full scientific community so that the general public will reap the benefits which such use will provide.published or submitted for publicatio

Effect of ECS on Passive Avoidance Learning with High and Low Intensity Foot Shock: Supplementary Report

A previous study showed that electroconvulsive shock (ECS) does not interact with foot shock intensity; however, ECS-produced retrograde amnesia was not evident on the first test trial following training. The present study decreased the learning trial-ECS interval to 2 sec. and retrograde amnesia was observed but ECS, again, did not interact with foot shock intensity (0.5 and 3.0 ma.). </jats:p

A Case Study Of The Effects Of Ritalin On The Performance Of Two Children

Many studies in recent years have looked at the effects of Ritalin on the performance of hyperactive children. In general, these studies have shown Ritalin to be significant in reducing the symptoms of hyperactivity usually referred to as impulsivity, short attention span, low frustration tolerance, and overly active. This study was designed to examine the effects of Ritalin on the performance of two children taking Ritalin on four tasks: concept learning, reaction time, visual discrimination, and memory
