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)

Describes an experiment that has been introduced in the organic chemistry laboratory program at Shepherd College, Shepherdstown, West Virginia. It illustrates microbial reaction and its role in the synthesis of vitamin C. (HM)

Presents a biochemistry experiment for college students that illustrates the purification of an enzyme. (HM)

Suggests an alternative to writing the traditional dissertation as a requirement for the doctorate in biology. Recommends the production of one or more journal journal-style manuscripts contributing knowledge in the field as a substitute. (MA)

Examines a number of factors that might influence performance in a college laboratory chemistry course. Compares the achievement and time for students doing a simulated or a laboratory experiment. Tries to identify differences in performance for students of different aptitude and possible interaction between types of experiment and student…

Describes two demonstration experiments for the chemistry laboratory: (1) Thermodynamic vs kinetic control and (2) Acid-Catalyzed Hydrolysis of Starch. (MA)

This first in a series of articles describing the state of the art of various branches of chemistry reviews inorganic chemistry, including bioinorganic, photochemistry, organometallic, and solid state chemistries. (SL)

A computer program which simulates an interstellar gas and dust cloud has been used to study Kirchhoff's laws of spectral analysis in introductory astronomy courses. The model parameters can be varied to stimulate various effects observed in actual clouds. Students are given exercises to use the program in a manner similar to a lab experiment.…

Explains the inertia ball demonstration qualitatively. For the advanced level the demonstration is treated as a forced harmonic oscillator and the results verified analytically. Computer-generated graphs show that with a rapid pull, the upper cord may break, or the upper and lower cords may break simultaneously. (Author/GA)

Calculates the energy-band structure of noninteracting electrons in a one-dimensional crystal using exact and approximate methods for a rectangular-well atomic potential. A comparison of the two solutions as a function of potential-well depth and ratio of lattice spacing to well width is presented. (Author/GA)

Describes a liberal arts physics course for all majors interested in holography or to satisfy the general education requirements. An outline of the course and some experience of offering it are given. (Author/GA)
