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 a simple inexpensive experiment designed to measure the levels of cortisol in a serum or plasma sample. (Author/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 flexible course structure in physics that allows the transfer of students between different programs, up to the end of second year of study. (GA)

Describes a demonstration of P and S (longitudinal and transverse waves), using students' bodies as media, to explain seismic waves in a geology course. (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)

Describes an experiment in nuclear physics to study radioisotopes. In this experiment the build-up of the activity of the source, 28-A1, is done first by irradiating it. (GA)

Describes the following: an electric circuit for an expensive photometer, an amplifier circuit capable of demonstrating many aspects of behavior of free and driven oscillators, and finally a projection recording system which uses an unmodified XY or XT recorder and a separate overhead projector. (GA)

Discusses two different uses of information theory in chemistry to present entropy and chemical structure analysis. (GA)

This course is based on the premise that a sound base in the mechanics and electrokinetics of the dispersed phase is essential for an understanding of the macroscopically apparent behavior of such disperse systems. (Author/BB)

This article looks at the problems of revision of laboratory courses. While revision of the syllabus of experiments is expensive, it is necessary to keep it up to date. The nature, causes, and rates of change in practical courses are discussed. (BB)

Describes several activities that can be done with laboratory mice to study the physiological role of oxytocin. Diagrams included. (MA)

Presents some problems for quantum chemistry courses based upon model pseudopotentials. Also includes some useful formulas and tables of parameters associated with these problems. (HM)
