Discusses the frequency of the circular movement of freely moving balls on rotating discs. A theoretical solution is given. (HM)

Describes a convenient, inexpensive experiment in enzyme kinetics developed for the undergraduate biochemistry laboratory at the University of Virginia. Required are a single beam visible spectrophotometer with output to a recorder, a constant temperature, a commercially available enzyme, substrates, and buffers. (BT)

Reviewed is a brief history of electronics technology, from the early beginnings of vacuum devices to development of solid state devices, silicon fabrication in the use of transistors, and integrated circuits. Educational needs at the university or polytechnic level are discussed. (CS)

Described is a method for integrating electrical and mechanical events of the cardiac cycle by measuring systolic time intervals, which involves simultaneous recording of the ECG, a phonocardiogram, and the contour of the carotid pulse. Both resting and stress change data are provided as bases for class discussion. (CS)

Highlighted are characteristics of programs written for a pocket-sized programmable calculator to analyze mass spectra data (such as displaying high resolution masses for formulas, predicting whether formulas are stable molecules or molecular ions, determining formulas by isotopic abundance measurement) in a laboratory or classroom. (CS)

Describes construction of two inexpensive three-dimensional models (tetrahedrons) using glass tubing and colored plastic sheeting. Diagrams show how these models are used in explaining how a point is plotted in a four-component system and how the composition of a point is deduced from its position in the model. (CS)

Discusses a one-semester course offered in the School of Chemical Sciences at the University of Illinois at Urbana which incorporates technical writing and the use of the chemical literature into a single course. (CS)

Describes a physical chemistry experiment that allows students to test the effect of ionic strength on the rates of a reaction between ions. The reduction of hexacyanoferrate III by ascorbic acid is detailed. Comparisons with the iodine clock reaction are made. (CS)

The synthesis of 1,4-diphenylbutadiene by means of the Wittig reaction is presented as suitable for organic chemistry students at the end of a basic laboratory program to apply laboratory skills and display understanding of the use of phase transfer catalysis and its application in syntheses. (CS)

Presented are questionnaire data for 1978-79 reported by 210 engineering and technical colleges and affiliate members of the American Society for Engineering Education. Questions were asked regarding engineering study and engineering research, such as graduate degree requirements, research areas of accepted doctoral theses, and personnel engaged…

An experiment is described in which undergraduate students can optimize the relative yield of sec-butylbenzene by varying molar ratio and temperature. (Author/SA)

The study reported indicates that despite the fact that undergraduate majors in elementary education could demonstrate attainment of a minimum standard on science content knowledge at one time, many were not able to demonstrate competence at the minimum standard at graduation time. (MK)

Examined are the status of, and potential for, university-industry research partnerships in science and engineering to enhance basic research and stimulate industrial innovation. The current and prospective roles of the federal government in stimulating such relationships are reviewed and discussed. (Author/CS)

Presents information on the Georgia Institute of Technology. This information includes: (1) a brief history of the institute; (2) names of the faculty members of the chemistry and metallurgy divisions; (3) undergraduate program; and (4) graduate program. (HM)

Presents Part II of a description of a computer-oriented course on process control which has been offered at the University of Wisconsin for undergraduate students. Lecture topics and laboratory experiments are also included. (HM)
