Describes an interface that uses semiconductor metal oxides to detect low gas concentrations. Notes the detector has long life, high stability, good reproducibility, low cost, and is able to convert the gas concentration to an electrical signal with a simple circuit. Theory, schematic, and applications are provided. (MVL)

Presents a low cost system with easily replaced electrodes for use in general chemistry. Notes the accuracy and wide applicability permit easy use in physical or quantitative chemistry experiments. Provides schematic, theory, and helpful suggestions. (MVL)

Provides methodology for carrying out the synthesis of sec-butyltoluene by the Friedel-Crafts alkylation of toluene. Suggests using simple elemental aluminum as the catalyst in place of AlCl3 or amalgamated aluminum. Notes satisfactory results for both macro- and microscale operations. (MVL)

Examines the top graduate programs in the geosciences listed in a 1983 "Changing Times" article. Notes the nine programs are substantially linked to each other by hiring each others' graduates, and hence, enhancing each others' reputation. (Author/MVL)

Describes how well-known scientists in China are attempting to win the understanding and trust of the general public as well as gaining prestige and social influence while promoting the cause of science. Measures employed include: the establishment of science institutions; professional organizations; events; the media; and science promotion…

Describes how government ministries and agencies are attempting to promote the cause of science. Describes the place of science in societies and the need for scientific popularization. States that work has been done in the areas of training, crops, and the establishment of bodies of three kinds. (RT)

Describes the diversity of channels through which the cause of science is being promoted and the special efforts being made to involve females in science and technology. Topics include the background of science popularization, tradition, innovation, television programs, science museums, the role of universities, youth activities, computers, and…

Presents an identification method which uses the process of elimination to identify pollination systems. Provides the polyclave key, methodology for using the key, a sample worksheet, and abbreviation codes for pollination systems. (MVL)

Describes a study in which students were required to write for five minutes after class on topics that interested them during the lecture. Reports a significant effect on achievement in a vertebrate biology class. Notes that no difference in attitude was found. (MVL)

Examines the influence of enzyme and substrate concentrations, pH, temperature, and inhibitors on catalytic activity. Follows the influence of different phosphate concentrations in the growth medium on enzyme activity. Studies regulation of enzyme synthesis by repression. Includes methodology for six experiments. (MVL)

Offers several advantages over other possibilities as the enzyme of choice for a student's first exposure to a purification scheme. Uses equipment and materials normally found in biochemistry laboratories. Incorporates several important biochemical techniques including spectrophotometry, chromatography, centrifugation, and electrophoresis. (MVL)

This syllabus describes the course background, central themes and issues, texts, resources, and recommended readings. Main topics are the sociology of information technology, computers and social change, telecommunications, computers and human interactions, applications in working, and social issues and political implications. (YP)

Shows how video recordings of the Brownian motion of tiny particles may be made. Describes a classroom demonstration and cites a reported experiment designed to show the random nature of Brownian motion. Suggests a student experiment to discover the distance a tiny particle travels as a function of time. (MVL)

Offers challenging work at a higher level of technique than most students meet in elementary laboratory work. Uses a combined weight and volumetric sequence not shown in textbooks. Notes modern rapid balances help lower evaporation loss during weighings. Discusses the balance, weights, and buoyancy considerations. (MVL)
