Provides background material on logic programing and presents PROLOG as a high-level artificial intelligence programing language that borrows its basic constructs from logic. Suggests the language is one which will help the educator to achieve various goals, particularly the promotion of problem solving ability. (MVL)

Explores the structural behavior of polyenic pi systems such as isomerization and conjugation. Uses the simultaneous spectrophotometric analysis of a beta-carotene and lycopene mixture. Presents an empirical method to determine the number of double bonds in the polyenic carotenoid. (MVL)

Discusses electron spin resonance, a form of magnetic resonance spectroscopy, used to study electronic structure of molecules with unpaired electrons. Studies benzosemiquinone radical anions which are long-lived and inexpensive. Uses a Project SERAPHIM computer program to perform a Huckel molecular orbital calculation. (MVL)

Compares two engineering education reports which urge the following needs and emphases: attract and retain minorities, retain students already in engineering school, and allow students to enter the engineering program at various levels. Criticizes the Office of Technology Assessment's report and supplies prescriptions for the future. (MVL)

Presents the results of a chemistry program held at Purdue University from July 31-August 4, 1988. Topics reported include: chemistry's past, present, and future; new directions in chemical education, demonstrations and laboratories; and instructional strategies. Lists the 391 papers given at the conference and the 22 workshops. (MVL)

Discusses the nature of a nuclear magnetic resonance (NMR) experiment, the techniques used, the types of structural and dynamic information obtained, and how one can view and refine structures using computer graphics techniques in combination with NMR data. Provides several spectra and a computer graphics image from B-form DNA. (MVL)

Discusses a computer database which includes optical properties of 142 minerals. Uses fuzzy logic to identify minerals from incomplete and imprecise information. Written in Turbo PASCAL for MS-DOS with 128K. (MVL)

Gives driving directions for a circuitous route while asking the drivers to make observations, measurements, interpretations and to locate features. Includes an example for the LaSalle Quadrangle, Illinois, which takes about one hour to complete. (Author/MVL)

Some of the topics that might be included in a nuclear chemistry section are explored. Offers radioactivity, closed shells in nuclei, energy of nuclear processes, nuclear reactions, and fission and fusion as topics of interest. Provided are ideas and examples for each. (MVL)

"Spreadsheets in Physical Chemistry" contains reviewed and classroom tested Lotus 1-2-3 and SuperCalc IV templates and handouts designed for use in physical chemistry courses. The 21 templates keyed to Atkins' physical chemistry textbook, the 7 numerical methods templates, and the 10 simulation templates are discussed. (MVL)

Discusses the four previous editions of the biochemistry medical textbooks called the "Nationwide Unified Textbooks." Notes the new (1989) edition is much smaller, is organized differently, has new material, has a reorganized Dynamic Biochemistry core, and shows great importance to clinical biochemistry. (MVL)

Presents three dimensional models of biological pathways for the following cycles: carbon, nitrogen, sulfur, and a combination of the three. Discusses steps involved in each cycle and breaks each cycle into trophic and environmental regions. (MVL)

Describes a chemistry software program that emulates a modern binary gradient HPLC system with reversed phase column behavior. Allows for solvent selection, adjustment of gradient program, column selection, detectory selection, handling of computer sample data, and sample preparation. (MVL)

Examines two instructional strategies, the traditional and learning cycle approaches, and compares them with regard to the variables of sequence, format, and necessity. Concludes that students exposed to the laboratory and discussion type had higher test scores than those in the lecture or reading groups. (Author/RT)

Discusses ways to generate and present images to students to study chemicals and chemical reactions. Contrasts current technologies with traditional means of displaying images. Summarizes experiences with the use of interactive videodisk-based lessons for chemistry instruction. (MVL)
