Accurate reproduction in plastic of the surface of the optical master to which a reflective finish may be applied is done by using backing from any suitable material to which cured plastic will adhere tightly. Plastics used for reflectors should be of the thermosetting or catalytically hardened type.
Handbook on typing nasa contractor reports for reproduction
Projecting a grid pattern on a steel layout board facilitates the alignment of camera copy for photo-offset reproduction. Small flat bar magnets fasten the copy to the board.
Reproduction of metal surface exposure to hypervelocity impact by micron-size particles
Slide rule-type color chart determines the final reproduced gray tones in the production of briefing charts that are photographed in black and white. The chart shows both the color by drafting paint manufacturers name and mixture number, and the gray tone resulting from black and white photographic reproduction.
Experimental reproduction of semicircular canal sickness symptomology in rotating environment - coriolis effect - aerospace medicine
Dynamic reproduction accuracy of machine tools with programmed control
Pattern recognition experiments based on set of photographic reproductions of video cloud patterns transmitted from Nimbus I satellite
Automated life detection on Martian environment based on metabolism, reproduction and chemistry
Coating for electronic components used in space applications has bacteriostatic qualities capable of hindering bacterial reproduction, both vegetative and sporulative viable microorganisms. It exhibits high electrical resistivity, a low outgassing rate, and is capable of restraining electronic components when subjected to mechanical vibrations.
Radiation effect on single cells and cell populations of Chinese hamster lung tissue is studied in vitro. The rate and position as the cell progresses through the generation cycle shows division delay, changes in some biochemical processes in the cell, chromosomal changes, colony size changes, and loss of reproductive capacity.
