Discusses the use of the properties of polyethylene, polypropylene, polyisobutylene, and their three epoxides to illustrate the relationships of entropy to molecular properties and the concepts of molecular chirality, geometry, and flexibility. (CC)

Reviews current research interests in photographic chemistry, involving two proposed models for spectral sensitization of crystal defects and impurities in the photolysis reactivity and the mechanisms of development and complexation. Establishment of photographic chemistry in a chemistry curriculum is recommended. (CC)

Discusses roles played by inelastic molecular collisions in gas molecular theories and suggests the inclusion of inelastic aspects in the freshman chemistry course. (CC)

Describes the features of the free radical, anionic, and cationic mechanisms of chain addition polymerization. Indicates that the nature of chain reactions can be best taught through the study of macromolecules. (CC)

Presents four examples which illustrate close relationships of chemistry to other disciplines. Indicates that chemistry is composed of many strongly interacting parts and a discipline which is donating to and borrowing from other disciplines. (CC)

Summarizes the thermodynamics of macromolecular systems, including theories and experiments of cyclic energy conversion with rubber and collagen as working substances. Indicates that an early introduction into the concept of chemical potential and solution thermodynamics is made possible through the study of the cyclic processes. (CC)

Describes the collisional properties as a logically essential component of the ideal gas model since an actual intraparticle process cannot support observable anisotropic velocity distributions without collisions taken into account. (CC)

This publication was developed as a portion of a two-semester sequence commencing at either the sixth or seventh term of the undergraduate program in electrical engineering at the University of Pittsburgh. The materials of the two courses, produced by a National Science Foundation grant, are concerned with power conversion systems comprising power…

Describes the status of teaching physics in the polytechnic institutions in the United Kingdom. The article also discusses: (1) development of courses in polytechnics; (2) types of physics courses; (3) role of physics departments; and (4) trends in teaching physics. (HM)

This volume is a report of the development of the first course in a two-semester sequence in Electronic Communications, for a new degree program in Electric Engineering Technology at Valencia Community College, Orlando, Florida. Evolution of the program is described with comments relating the philosophy and importance of a communications sequence.…

During 1979, nine National Workshops were organized in Afghanistan, India, Japan, Malaysia, Nepal, Philippines, Sri Lanka, Thailand, and Socialist Republic of Vietnam to analyze national experiences relating to the designing and developing of innovative science curriculum and instructional materials for linking science education to real-life…
