Describes a method of producing photographs of X-ray diffraction patterns using Kodak X-ray film. (SL)

This annotated bibliography is intended for public library collections, although many selections are worthy of inclusion in college or special libraries. Subdivisions listed are: animal life, anthropology, biology, earth sciences, energy, environmental sciences, health, natural history, plants, psychology, and transportation. (JAB)

The 35 titles in this annotated bibliography complete the list of 100 best sci-tech titles; the first 65 appeared in the March 1, 1978 issue. Major subject subdivisions in this addendum include astronomy, earth sciences, and general science. (JAB)

Compares differences in function and behavior of two oxygen-binding proteins, myoglobin found in muscle and hemoglobin found in blood. Describes the mechanism of oxygen-binding and allosteric effect in hemoglobin; also describes the effect of pH on the affinity of hemoglobin for oxygen. (CS)

Reviews congressional appropriations which have led to the development of science education curriculum materials and science teacher education. Describes the present reluctance of Congress to appropriate more funds for additional efforts. (CP)

Presents demonstrations on (1) ion exchange (softening hard water) and (2) vapor pressure measurement. (RH)

Discusses four periods of development in American physics during the last two hundred years and the discoveries and research of both Benjamin Franklin and Henry Rowland. (MLH)

Discusses how sophisticated instrumentation techniques yield practical results in three typical materials problems: fracture analysis, joining, and compatibility. Describes techniques such as scanning and transmission electron microscopy, and Auger spectroscopy. (MLH)

Many standard physical chemistry textbooks contain ambiguities which lead to confusion about standard electrode potentials, calculating cell voltages, and writing reactions for galvanic cells. This article shows how standard electrode potentials can be used to calculate cell voltages and deduce cell reactions. (Author/RH)

Discusses some aspects in X-ray topography, including formation of dislocations, characteristics of stacking faults, x-ray contrast in defect inspection, Berg-Barrett technique, and Lang traversing crystal and Borrmann's methods. (CC)

Discusses a four-step instructional presentation in which the twin on the earth is demonstrated older than the twin aboard a spaceship on the basis of the relativistic Doppler effect. Concludes that both twins can meet again at the same place in space at the expense of time. (CC)

One of a series on different topics designed to guide college physicists to some of the literature and teaching aids that may help them improve course content. (DF)

Describes a lesson in aerodynamics'' that involves construction and flying of kites. (SP)
