The logic control system of a computer automatically sequences
logic operations which direct how and when memory stored instructions
and data are processed in the digital registers.
This thesis contains circuit schematics and test results of a
nanosecond response logic - control system for the Galaxy Computer.
The circuit designs...
This paper is a study of the fatigue properties of the alloy
columbium - one percent zirconium in reverse bending. This paper
also is a design study of a satisfactory plate reverse bending fatigue
specimen configuration for use with the General Electric PRB pneumatic
testing machine. Selected tensile tests were...
The mound-building harvester ant, Pogonmyrmex owyheei Cole,
(formerly included in the species occidentals) is widely distributed
on the semi-arid rangeland east of the Cascade mountains in Oregon.
Because of its seed foraging and vegetation clearing habits, this ant
has been considered as a possible competitor with livestock and
wildlife for...
White muscle disease or muscular dystrophy of sheep is a selenium
responsive malady common to many areas with an inherent natural
deficiency of selenium in the forage. The disease can be prevented in
lambs by adding trace amounts (approximately 0.1 ppm) of selenium to
the otherwise selenium deficient, forage fed...
In 1957 three Douglas-fir stands (15-, 25-, and 40-year-old age classes) were selected on a tree farm in the Cascade foothills of
northwestern Oregon to study factors affecting site productivity. Soil-moisture, soil-temperature and seasonal radial- growth pattern measurements were made with a Colman moisture meter and a dial gauge dendrometer...
