Analysis and optimization of an omnidirectional direction-finding system
System determines the direction of arrival of an electromagnetic wave with the direction information in a readily usable form. It presents a relatively small physical structure and does not require mechanical positioning.

Laser method for finding axis of rotation
Illumination of rotating surface with laser beam and examination of interference patterns resulting from diffused reflections determines position of axis and direction of motion. Interference patterns are viewed through a lens or recorded on film as circular streaking patterns.

Experimental interstellar organic chemistry: Preliminary findings
In a simulation of interstellar organic chemistry in dense interstellar clouds or on grain surfaces, formaldehyde, water vapor, ammonia and ethane are deposited on a quartz cold finger and ultraviolet-irradiated in high vacuum at 77K. The HCHO photolytic pathway which produces an aldehyde radical and a superthermal hydrogen atom initiates solid phase chain reactions leading to a range of new compounds, including methanol, ethanol, acetaldehyde, acetonitrile, acetone, methyl formate, and possibly formic acid. Higher nitriles are anticipated. Genetic relations among these interstellar organic molecules (e.g., the Cannizzaro and Tischenko reactions) must exist. Some of them, rather than being synthesized from smaller molecules, may be degradation products of larger organic molecules, such as hexamethylene tetramine, which are candidate consitituents of the interstellar grains. The experiments reported here may also be relevant to cometary chemistry.

Neurophysiological findings relevant to echolocation in marine animals
A review of echolocation mechanisms in marine mammals, chiefly porpoises, is given. Data cover peripheral auditory and central neurophysiological specializations favorable to the analysis of echolocating clicks and their echoes. Conclusions show (1) signals are received from 50 up to at least 135 kHz, (2) sound is received through the mandible skin, and (3) the midbrain sites are insensitive to low frequencies (below 6 kHz).

Experimental findings from zero-tank net positive suction head operation of the J-2 hydrogen pump
The results of a series of liquid hydrogen turbopump tests to demonstrate the feasibility of zero-tank net positive suction head are presented. A J-2 engine hydrogen pump and S-IVB stage fuel feed system were used for this investigation. The pump was operated at flows and speeds equivalent to normal J-2 engine operating conditions and at hydrogen bulk temperatures between 39 and 45 R. These tests show zero-tank not positive suction head to be a realistic operating mode that should be considered for future applications.

Biomedical findings on American astronauts participating in space missions.
Zero-gravity adaptive responses of man are discussed on the basis of biomedical data for 54 American astronauts, covering performance, locomotion, orientation, sleep and physiological and functional characteristics. Figures and diagrams are given for cardiovascular adaptation, weight loss, endocrine and electrolyte responses, fluid balance, skeletal responses, muscular and neuromuscular changes, exercise response tests and work capacity indicators. A review is given of current hypotheses concerning the processes involved in human adaptation to zero gravity. It is concluded that the immediate response of the body to weightlessness is a redistribution of the total circulating blood volume, leading to a loss of water, sodium and potassium through the kidneys and, thus, to a loss in total body weight.
