Describes a simple microwave interferometer capable of measuring small phase shifts. Proposes laboratory exercises involving the use of the interferometer in the determination of refractive indices of gases and the analysis of the reflection in a test chamber. (Author/CP)

Presents three activities: (1) the investigation of the purity and stability of nicotinamide and flavin coenzymes; (2) desk-computer fitting of a two-exponential function; and (3) an interesting and inexpensive solubility product experiment for introductory chemistry. (RH)

Describes an experiment in which a racemic mixture of a coordination compound is resolved. (MLH)

Describes an experiment which quantitatively determines glucose by a spectrophotometric measurement of the colored complex formed between glucose and an amine. (MLH)

Describes the electronic circuitry which can be used to demonstrate the buildups of Poisson distributions with very high precision. Analysis of the data obtained is included in the paper. (CP)

Describes an undergraduate experiment that illustrates the use of thin-layer chromatography. (MLH)

The evolution of a laboratory oriented undergraduate plasma physics course is described. Brief accounts of the 14 experiments utilized in the course are provided. (CP)

Describes experiments, demonstrations, activities and ideas relating to various fields of chemistry to be used in chemistry courses of secondary schools. Three experiments concerning differential thermal analysis are among these notes presented. (HM)

Describes a computer-based instructional model for the physiology laboratory. Attempts to develop an efficient and low-cost system designed to provide dynamic student/machine interaction are discussed. (MA)

Discusses the kinetic behavior associated with the interaction of metal ions with apocarbonic anhydrase, focusing on the formation of two metallocarbonic anhydrase--the biochemically active Co(II) and the inactive Ni(II)derivatives. (GA)

Describes the college level experiments: a simple measurement of the isotopic abundance of 40-K, a mechanical experiment, on kinetic energy, and on soap films between wedged plates. (GA)

Describes three experiments to demonstrate several aspects of artificial radioactivity. Metal foils were activated, using slow neutron bombardment. (GA)

Describes a laboratory game called SUPERCHARGE, used as an aid to help students understand the concept of equipotential surfaces generated by distributions of charges. (GA)

Describes an experiment for measuring the lifetime of the 60-keV state in 237-Np which is populated in the alpha decay of 241-Am. The technique used is the delayed coincidence method using a time-to-pulse-height converter. (Author/GA)
