This syllabus reviews information concerning calcium and phosphate regulation. Topics of interest include the following: calcium metabolism, phosphorus metabolism, bone, parathyroid hormone, calcitonin, and vitamin D. (CS)

Describes the activities, goals, resource materials, and ways to participate in National Science and Technology Week. (MDH)

The Long Duration Exposure Facility (LDEF) has been designed to take advantage of the two-way transportation capability of the space shuttle by providing a large number of economical opportunities for science and technology experiments that require modest electrical power and data processing while in space and which benefit from postflight…

Various aspects of the current evolution/creationism controversy are reviewed including the impact of attempting to remove evolutionary material from textbooks and including creationist material. A number of viewpoints, opinions, and references from current literature are cited. (DS)

Highlights major accomplishments, developments, and research in the sciences during 1982, focusing on the space sciences, astronomy, medicine, biology, psychology, chemistry, physics, environment, and zoology. Includes a brief statement of the 1982 Nobel Prize winners' research in medicine, chemistry, and physics. (JN)

Developed as part of a document series in UNESCO's Science and Technology Education program, this volume reviews the major trends and cites the improvements in the natural science and mathematics education in the Soviet Union. Separate units are provided for the discipline areas of mathematics, physics, chemistry, and biology. These sections…

Provides background information for teachers on the nature and production of antibodies. Points out that the production of monoclonal antibodies blends the malignant with the beneficial to create a medical tool of exciting potential. (JN)

Provides a method for correcting the photoemission from a collector when using the photoelectric effect experiment to determine Planck's constant. The problem results from a negative current through the cell and makes the measurement of the cutoff potential difficult. (DH)

Describes the theory behind the workings of the Hubble Space Telescope, the spherical aberration in the primary mirror that caused a reduction in image quality, and the corrective device that compensated for the error. (JRH)

This information packet on quasars consists of an introductory paper, four articles from "Mercury," a journal of the Astronomical Society of the Pacific, and a bibliography. Methods used to measure distances in the universe and the nature of quasi-stellar objects (QSO's), the name preferred by many workers in the field, are discussed in…

Washington, D.C. has been associated with many distinguished chemists. Since its incorporation in 1802, a steady stream of chemists have made impressive contributions to chemical science, health, information science, minerology, food science and other areas. The majority of these chemists have been associated directly or indirectly with the…

This section of the journal includes several short notes on science activities and materials for secondary schools. Activities and materials are included that relate to biology, microbiology, microcomputers, chemistry, and physics. (RH)

Presents information on the moment of inertia of a tennis racket about its principal axes. This information (not available from conventional sources) is useful since it influences how the racket plays and how the racket feels when it is swung. In addition, measurements of motion can be easily made by undergraduate students. (JN)

Discusses the acoustics of bells by examining what determines the quality of a bell, the frequency it emits, and the note perceived by the listener. The analysis concentrates on a ship's bell but also considers several handbells. Laboratory bench set up for studying bells and nodal lines of bells are illustrated. (BC)

Presents a nonmathematical approach to help students understand that there are two types of coherence and to associate coherence as a property of the illumination at an object itself. The approach also lends itself to an introduction to the Fourier approach for analyzing imaging systems. (JN)
