Metabolic breath analyzer

Instrument measures metabolic breathing rate and dynamics of human beings in atmospheres ranging from normal air to 100 percent oxygen at ambient pressures from 14.7 to 3.0 psia. Measurements are made at rest or performing tasks up to maximum physical capacity under either zero or normal gravity

[Review of] Michael Eric Dyson. I May Not Get There With You: The True Martin Luther King Jr.

Michael Eric Dyson\u27s approach to his biography of Dr. Martin Luther King entitled I May Not Get There With You : The True martin Luther King Jr. is unlike the numerous other biographies of King in that the method he employs in recasting the life of Dr. King is described as Bio-criticism

Sensitometric crossover for 2485 in balloon observation astronomical program

Photographic film processing support is described for the CREPE 4 project, a high-altitude balloon study of cosmic radiation. The processing procedures are summarized, and recommendations are made for the size and thickness of film to be used in future projects

Black-and-white separations of spacecraft original film

Separation systems and a detailed procedure for the production and evaluation of separation negatives are reported. It is shown that these separation negatives have excellent stability, and meet archival storage requirements

S-190 exposure verification flight test

A flight test was conducted to determine the optimum exposures for the Skylab S-190A experiment. An aircraft multispectral photographic system (AMPS) which is installed in the NASA Earth Resources aircraft NP3A was used to simulate the S-190A system. The same film emulsions to be used for S-190A were used in the flight test. These rolls were on factory-loaded spools for use in the AMPS camera system. It was found that some variation is to be expected between these rolls and the S-190A flight loads

Feasibility of using Eastman Kodak type 3400 film for high altitude multispectral photography

A photographic test flight of the NASA RB-57F was conducted on March 25, 1972, over Houston and West Texas, to determine the suitability of Eastman Kodak type 3400 film as a replacement for type 2402 film in the Hasselblad cameras. An additional purpose was to test GAF film type 2914, a new black and white film similar to 2402, but with higher maximum gamma and greater dynamic range

Analysis of sensitometric data for earth resources black and white films

Methods are described for relating the densities in a roll of duplicate imagery to the exposure on the original by generating the system response curve. A four-quadrant tone-reproduction cycle is also described
