Reports a procedure for the formation of alkyldiazenido complexes of molybdenum in the absence of dioxygen, suitable for inclusion in an advanced inorganic chemistry laboratory. Includes background information and experimental procedures for two complexes. (SK)

Suggests that students study heats of neutralization of a 1 M solution of an unknown acid by 1 M solution of a strong base using the method continuous variation. Reviews results using several common acids. (SK)

Reviews advantages of computer-based instruction in physics. Discusses ways computers can aid individual students; the computer as an intellectual tool; the computer controllable world; the computer as a testing and diagnostic aid; the Socratic dialog on computers; and various aspects of computer-based instruction for the future. (SK)

Reports results of a survey in which 110 universities were selected to respond to questions regarding approximate age and cost of the instruments used in three major areas: separations, spectroscopy, and electroanalysis. Respondents (N=41) also indicated which pieces of equipment were used in undergraduate courses or were used for research. (CS)

Discusses the role that radiation-chemical techniques play in the study of the electron transfer process. (CS)

Describes some basic findings in the radiation chemistry of genetic material derived from studies of model systems. Uses these findings to extrapolate the consequences of radiation damage to DNA within cells. (CS)

Discusses the effects of radiation on dividing cells and factors influencing these effects; also briefly reviews the radical mechanism for radiation damage. Emphasizes the importance of oxygen in radiation effects. (CS)

Discusses various aspects of radiation damage to biological material, including free radical mechanisms, radiation sensitization and protection, tumor hypoxia, mechanism of hypoxic cell radiosensitization, redox model for radiation modification, sensitizer probes of cellular radiation targets, pulse radiolysis studies of free radical kinetics,…

Describes common features in the radiation chemistry of food components, and illustrates how product yields are predicted. Presents data that pertain to the radiolysis of the nitrate ion, metmyoglobin, myosin, and tripalmitin. (CS)

Describes various aspects of a newly-developed computer-assisted drafting/computer-assisted manufacture (CAD/CAM) facility in the chemical engineering technology department at Broome Community College, Binghamton, New York. Stresses the use of new instruments such as microcomputers and microprocessor-equipped instruments. (CS)

Describes a self-instructional game which simulates scientific research in bacterial genetics. (CS)

Summarizes the experiences of a zoology professor attempting to construct a student-centered course in neurophysiology. Various aspects of the organization and conduct of the course are described, including the beginning experience, topics of interest, lecture, laboratory, computer simulation, examinations, student lectures. Evaluation of the…

Points out that quantum mechanics interpretations, using Heisenberg's Uncertainty Relations for the position and momentum of an electron, have their drawbacks. The interpretations are limited to the Schrodinger theory and fail to take into account either spin or relativity. Shows why spin cannot be ignored. (Author/GA)

Describes a multichannel analyzer built using eight-bit S-100 bus microcomputer hardware. The output modes are an oscilloscope display, print data, and send data to another computer. Discusses the system's hardware, software, costs, and advantages relative to commercial multichannels. (Author/GA)

This heat transfer problem requires students to analyze the feasibility of moving icebergs from the Antarctic to Saudi Arabia to provide fresh water. (BB)
