Material presented is adapted from Desalination with Solar Energy, a paper presented before the International Symposium on Energy Sources and Development, held in Spain in 1977. Desalination systems energized by the sun, conditions governing their efficiency, and their costs are discussed. (HM)

Traces the development of stabilized lasers from the Massachusetts Institute of Technology passive-stabilization experiments of the early 1960s up through the current epoch of highly stabilized helium-neon and carbon dioxide and continuous wave dye lasers. (Author/HM)

Discusses the use of laser spectroscopy in determining the presence of specific gaseous constituents. Three of currently used modes for laser detection of pollution are reviewed; (1) long-path measurements; (2) laser raman (differential absorption) measurements; and (3) optoacoustic detection. (HM)

Describes a currently used picosecond spectroscopy system capable of reliably recording picosecond events. Two areas of picosecond research are discussed: one concerns the interaction of electrons in fluids; the second, the primary events in vision. (Author/HM)

Presents a bibliography of books for upper elementary students. The books deal with aspects of space in the seventies, changing concepts of the universe, and how today's science and technology are trying to answer the questions these concepts raise. (Author/GA)

Because there are more schools than any other type of public building, schools are architectural bellwethers, the first reflection of shifts in national priorities. In this article architectural trends in educational institutions are discussed in relation to energy conservation. Examples are offered of schools which utilize solar energy.…

The early history of disinfection and sterilization, physical methods, electron irradiation, sonic and supersonic waves, alpha, beta, gamma, cathode, x-rays, and ultraviolet radiation, and heating and freezing are covered. (BB)

Expressions to describe fringe contours in the region of interference of two coherent beams are derived for three combinations of plane and spherical wave geometrics. (Author/SL)

Describes a device for measuring the absorption of radiation for a quantitative analysis chemistry laboratory course. (SL)

Considers the problem of the radiation emitted by a charged particle undergoing eternal hyperbolic motion. (Author/SL)

Presents a brief description of the solar heating system that is incorporated into the design of a private girls school in Greenway, Virginia. (MDR)

Presents aspects of multipole radiation theory suitable for a senior level course in nuclear physics. (SL)

Traces the history of solar energy development. Discusses global effects (temperature, particle and other pollution) of burning fossil fuels. Provides energy balance equations for solar energy distribution and discusses flat plate collectors, solar cells, photochemical and photobiological conversion of solar energy, heat pumps. (CS)

Describes procedure for making X-ray photographs on Polaroid 3000 black and white roll film. (SL)

Provides an inventory of international radioactive waste-management policies and repository siting decisions for North America, Central and South America, Europe, Asia, and Africa. This discussion stresses the important role of demographic, geologic, and political factors in siting decisions. (Author/BSR)
