Describes a simple computer-based information retrieval system which manipulates non-numeric information using a program that simulates a three-level information storage system. The system is used to create, modify, and selectively search a data base both interactively and noninteractively. (MLH)

Presents an account of the life of Otto Diels and explains his research on the constitution of cholesterol, the Diels-Alder reaction, and synthesis of cantharadin. (GS)

Presents a key to determine the appropriate statistical test for a given set of biological data. The key is not all inclusive, but serves as a guide to the commonly used procedures. (GS)

Explains the techniques of experimenting with the protozoan Colpoda cucullus to learn about its habitats, dispersal and adaptations. (LS)

Describes recent research that has made solar energy economically competitive with other energy sources. Includes solar energy building architecture, storage systems, and economic production data. (MLH)

Describes the initially ignored research performed in 1900 by Archibald Garrod concerning the link between heredity and biochemical reactions. (MLH)

Three questions and answers involving chemistry are presented. Question one involves elimination of reptiles from the earth; the second considers chemical effects on taste acuity; the third relates to muzzle velocity of a projectile fired from a gun and temperatures inside the cartridge. (MLH)

Discusses various topics in color chemistry, including the electromagnetic spectrum, the absorption and reflection of light, additive and subtractive color mixing, and the molecular structure of simple colored substances. (MLH)
