Expands the basic concepts regarding the radiation chemistry of simple aqueous systems to more complex, but well defined, organized assemblies. Discusses the differences in behavior in comparison to simple systems. Reviews these techniques: pulse radiolysis, laser flash, photolysis, and steady state irradiation by gamma rays or light. (CS)

Summarizes the technology of the field known as radiation processing, the term used to describe the large scale production or modification of materials by ionizing radiation. (CS)

Describes an interdisciplinary student experiment based upon the radiation effects on polymers, integrating some of the fundamentals of radiation chemistry, polymer chemistry, and material science. Also demonstrates how the information gained in the experiment has direct commercial application in product manufacture or processing. (CS)

Compares two methods for computer generation of tests: question retrieval and question generation. Both techniques are described with specific applications for university teaching. Also evaluates the effects of these methods on student performance. Future developments of computer assisted test construction are also discussed. (CS)

A Freshwater Winter ecology course for science teachers is described. Included are a description of the lectures, field activities, field techniques, sampling areas, and sampling methods. (DS)

Reviews proceedings of a symposium sponsored by the Education Committee of the American Physiology Society. Summarizes the teaching of respiratory physiology to medical students at the following medical schools: University of California at San Diego, McMaster University, University of Pennsylvania, University of Gottingen (Federal Republic of…

Explains that the efficiency and the useful power available from a windmill turbine, of a laminar-flow model, will vary due to rotational kinetic energy of the downwind stream and turbulent mixing from outside the boundaries of the idealized stream. (GA)

Derives a familiar torque-angular momentum theorem for the electromagnetic field, and includes the intrinsic torques exerted by the fields on the polarized medium. This inclusion leads to the expressions for the intrinsic angular momentum carried by the radiation traveling through a charge-free medium. (Author/MA)

Explains why failure to distinguish clearly between three concepts: a vector, its components, and its representatives, renders understanding of how the representations of the rotation group are constructed from products of the spin-half representation, difficult to comprehend. (Author/GA)

Describes a simple demonstration that shows the change in molecular density and the reduction in pressure of air in a centrifugal field. Uses two circular disks with the same radius and rotating with the same angular velocity, in loose mutual contact, around their symmetry axis. (GA)

An approach to the teaching of steady-state recycle calculations is presented. Included are the solutions to two sample problems. (BB)

Presents general directions on how the Swedish university physics curricula should be designed to meet future needs. How to improve the cooperation between industry and university is also discussed. (HM)

Describes how Dartmouth College has integrated computers into the total curriculum of that institution with implications for individualized instruction. (CS)

Examines research which was performed in order to investigate, in the context of colleges of further education, the relationship between performance on divergent and convergent thinking tests and between performance on divergent thinking tests and academic attainment. (CT)

Presents information on interfacing microcomputers for scientific users of S-100, TRS-80, PET, and Apple microcomputers, including device-select pulses, programing considerations, data input, data output, and power supplies. (JN)
