Phenylketonuria is an inborn error of metabolism, which in the past caused mental retardation as well as behavioral disturbances. Initially the discovery of diet therapy eliminated the behavioral disturbances, but not...
The data gathered for the study of the health status of freshmen
at Oregon State University were derived by an analysis of health history

Commerical preparations and published formulations using reagent chemicals for seawater substitutes were not biologically acceptable to Mytilus edulis embryos, in that calcification did not occur. When Leslie coarse hide salt was used as the source of NaCl for literature formulations, most formulas provided some success in the development, growth and...
A study of the population ecology of Columbia River fall chinook
salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt
to determine the cause of a serious decline in this run which occurred
in the early 1950's. Fluctuations in abundance of major salmon runs
the North Pacific were examined to...
A multivariable model describing the system response
(weld tensile strength of 6061-T6 aluminum) of a percussive
stud welding system as a function of five natural
(external) system variables was developed. The five natural
system variables were 1) static weight of the drop-shaft (W), 2) initial stud base height (H₀), 3)...
