A series of eight trials was conducted to determine if supplementation
with arginine improved growth of young rats, Japanese quail
and swine fed low-lysine diets. In five rat trials, with a variety of
basal diets, no evidence of a "sparing effect" of arginine on the lysine
requirement was found. A...
Prediction equations were developed for estimating the flow
regime at ungaged stream locations in the Oregon coastal range.
Principal components analysis was used to screen the initial data set
of physiographic and meteorological parameters. The final regression
equations for predicting mean monthly flow had standard errors of
estimate ranging from...
Thais (Nucella) emarginata is a common predatory gastropod of the
rocky intertidal system of western North America. It is usually found at
low tide on top of its sedentary prey, barnacles and mussels. Thais
is also highly polymorphic for shell color, and breeding of isolated
females has shown that the...
Frequency distributions are calculated for the optical
decay of two atomic states which are coupled by a strong,
linear rf field. Both the rotating and the counter-rotating
components of the field are maintained throughout the
calculations. For strong fields many peaks are present in
the frequency spectrum and are explained...
The causes of turbidity in impounded and released reservoir
water are studied. Seven Willamette Basin reservoirs are compared
to isolate watershed and reservoir characteristics which produce variations
in turbidity. Of the seven, Hills Creek Reservoir is examined
in detail. Particular features of the basin and impoundment are
studied to isolate...
