A series of audiovisual presentations of laboratory techniques, instructions, and principles for intelligent operation of instrumentation have been developed. Discusses utilization of these slide/tapes educational benefits, and comparison with commercial tapes. Titles of the slide/tapes are provided. (Author/JN)

Historical reconstruction of Dmitrii Mendeleev's part in the creation of the Periodic Table of Elements illustrates how important the process of textbook writing was in this scientific development. A clear difference is seen between logical reconstruction of the discovery process and the insights provided by historical reconstruction of the same…

A survey of male Ph.D.s in chemistry and psychology at selective liberal arts colleges showed the publication rate of department colleagues to be positively related to current publication productivity of the focal faculty member. Colleagues influenced research activity of faculty with low prior research levels, but not higher prior levels.…

Contributions in mineral-deposit model formulation, geochemical exploration in glaciated and arid environments, analytical and sampling problems, and bibliographic research were made in symposia held and proceedings volumes published during 1982. Highlights of these symposia and proceedings and comments on trends in exploration geochemistry are…

Provides instructions for interfacing a pH meter directly to an Apple II microcomputer without an analog-to-digital converter. Includes program listing (with enough remark statements to make it self-documenting) in Integer Basic to display the pH readings. (Author/JN)

Highlights major science news stories of 1982 reported in "Science News." Categories include space/astronomy, biology, chemistry, medicine, energy, physics, anthropology/paleontology, earth sciences, technology, behavior, science/society, and the environment. (JN)

Three chemistry demonstrations are described: (1) modification of copper catalysis demonstration apparatus; (2) experiments in gas-liquid chromatography with simple gas chromatography at room temperature; and (3) equilibria in silver arsenate-arsenic acid and silver phosphate-phosphoric acid systems. Procedures and materials needed are provided.…

Describes an experiment to examine the kinetics of carbamate decomposition and the effect of buffer catalysis on the reaction. Includes background information, laboratory procedures, evaluation of data, and teaching suggestions. (Author/JN)

Describes rationale, need, and purpose of three lists of objectives (included in appendices) of objectives for skills and abilities related to experimental, practical work in biology, chemistry, and physics. (SK)

Describes a variable-height wheelchair which can be raised 18 inches above normal chair height by means of an electrically operated screw jack. Photoqraphs illustrate the chair to be convenient and helpful for a handicapped chemistry student. (Author/SK)

Lists in tabular form and discusses information concerning total numbers of bachelor's degrees, master's degrees, and Ph.D. degrees awarded in 1979-1980 by departments whose chemistry programs are ACS-approved. Also includes numbers of chemical engineering graduates from institutes whose programs are accredited. (CS)

Contains short descriptions of computer programs or hardware that simulate laboratory instruments or results of kinetics experiments, including ones that include experiment error, numerical simulation, first-order kinetic mechanisms, a game for decisionmaking, and simulated mass spectrophotometers. (CS)

Describes an undergraduate laboratory experiment using viscosity to follow the progress of the contractile process in muscles. This simple, short experiment illustrates the action of ATP as the source of energy in the contractile process and the catalytic effect of calcium ions as a control in the energy producing process. (CS)

Presents in tabular form chemists' salaries. Reviews salaries of chemists with B.S., M.S., and Ph.D. degrees, chemical engineers, college faculty, industrial chemists, women, and employment status of chemists surveyed. Indicates relatively low unemployment and that medial salary for chemists has increased 11% between March 1980 and March 1981. (JN)

Summarizes contents of a guide titled "Teaching Chemistry to Physically Handicapped Students," designed primarily for college-level teachers and intended to familiarize teachers with the practical aspects of teaching chemistry in the classroom and laboratory to students with physical handicaps. (CS)
