Cathodoluminescence is visible light emitted from a specimen when it is bombarded with electrons. A technique known as cathodoluminescence petrography can provide information especially useful in studies or courses related to mineralogy and petrology. The technique is briefly presented, along with examples to illustrate typical results. (Author/WB)

Discusses three major reasons why more women do not pursue research positions in science and technology: (1) lack of awareness of female role models; (2) social rejection in graduate schools and sexual pressures on the job; and (3) lack of technological literacy. Makes recommendations to solve these problems. (JOW)

Describes specific activities and accomplishments of the President's Office of Science and Technology Policy. Addresses policy issues related to strengthening the U.S. science and technology enterprise, fostering industrial innovation, enhancing relationships among government, industry, and universities, and improving the regulatory process.…

Discusses the impact of computers on research in speech, atmospherics, psychology, and computing science. (MLH)

Discusses the renewed interest in superconductivity research and describes the differences between the two basic types of superconductivity. (MLH)

Data gathered from 24 federally funded "demonstrations" of new project technologies provide information for this discussion which includes rationale for government involvement, scope of federal demonstration activities, and framework for analyzing outcomes in terms of project goals. (CS)

The Creativity in Science and Technology (CREST) award program is a national program designed to encourage secondary students to conduct their own experimental project in science and/or technology. Reports on a national evaluation of the CREST program which concludes that CREST is a useful method of incorporating scientific investigations into the…

Discusses role of laboratory techniques in scientific investigations. Describes Rutherford's development of scattering techniques and von Wassermann's development of test for syphilis. States that discovering an effect requires a brilliant scientist, however, making it a technique requires that it be made usable by ordinary people. Uses Moseley's…

A transcript of the hearing that discusses the findings and recommendations that are part of the Office of Technology Assessment's (OTA's) report on federally funded research is presented. The report evaluates the nature and distribution of research funding and decision-making and suggests alternative approaches that the Federal Government can…

Presents the latest developments concerning the following topics: astrogeology, coal, deep sea drilling project, engineering geology; environmental geology, exploration geophysics, geochemistry, geodynamics project, hydrology, industrial minerals, international geology, mapping, mathematical geology, metals, mineralogy, oil and gas, invertebrate…

The author contends that scientists must learn to bear the risks they create and can not put voluntary safeguards and restrictions upon scientific research. Scientists must make rational decisions about future risks and be fully aware of the technological imperatives that must control human destiny. (BT)

Describes the design of ion selective electrodes coupled with immobilized enzymes which operate either continuously or on drop-sized samples. Cites techniques for urea, L-phenylalanine and amygdalin. Micro size electrodes for use in single cells are discussed. (GH)

Spill control methods have been developed to control, treat and monitor spills of hazardous materials during their manufacture, transport, and storage. Spills on both land and water, and methods of treatment and control in these environments were studied. A discussion of detection and monitoring equipment and protective clothing concludes this…
