Fruit set of sweet cherries was reduced if sprays containing fluoride (sodium or ammonium fluoride or hydrofluoric acid) were applied during anthesis. Sprays applied at other times during the fruit-growing season caused fruit and leaf symptoms, depending on the concentration of fluoride, but no reductions in fruit set. Symptoms of...
The formation of shear bands in isotropic micropolar
elastic materials is considered in this thesis. The
investigation concerns localized deformation fields due to
jumps of second-order gradients of displacement across a
standing singular surface. Such a standing surface gives
rise to a shear band. The condition for the existence of...
One hundred and four seed sources from throughout the range of Douglas-fir (Pseudotecia menzieaii (Plirb.) Franco)
were analysed at 20 enzyme loci to determine patterns of genetic variation and to examine intraspecific phylogeny. On average the seed sources were polymorphic at 37 percent
of the loci (range 5.0-65.0), with mean...
The purpose of this study was to develop a model to calculate
gamma ray pulse height distributions that closely approximate
measured ones. The model was used to produce a pulse height
distribution for a postaccident coolant sample from a nuclear
reactor. Lower limits of detection were calculated for certain key...
Ethanol caused altered mobility of the lipophylic probe,
1,6-diphenyl-1,3,5-hexatriene in plasma membrane preparations of
Saccharomyces cerevisiae. Because lipids had been shown to protect
yeast against ethanol toxicity, sterols, fatty acids, proteins, and
combinations of these were tested, but protection from growth
inhibition was not seen. Ethanol-induced prolonged lag periods and...
The basic objective of this thesis was to estimate the
economic effects of yield grade standards for carcass beef
on the various market sectors of the Canadian beef industry.
The adoption of the standards was expected to enhance
consumer demand, improve efficiency within the processing
and marketing services sectors, and...
English sole is a major contributor to Oregon and Washington groundfish resources. In accordance with the continued trend of increasing fishing effort, in 1975 Oregon State University Sea Grant
funded an extensive groundfish research program: the Pleuronectid Project. The purpose was to provide information to assist resource management agencies. This...
The purpose of this study was to identify significant differences
in body composition, body cathexis, and attitudes toward obesity
of women in various age groups involved in different levels of physical
exercise.
A total of 216 women, ranging in age from 17 to 64, took part in
this study. They...
Two types of linear random wave simulation methods are investigated;
viz., (1) Deterministic Spectral Amplitude (DSA) and (2) Nondeterministic
Spectral Amplitude (NSA). These linear simulations are extended to
second-order in a perturbation expansion in the frequency domain by
utilizing a Fast Fourier Transform (FFT).
The nonlinear interaction matrix for waves...
Daily commercial albacore catches made by U. S. trollers fishing
off central California and Oregon are correlated with daily upwelling
indices and predictive catch models are developed.
Models predicting total catch/day and catch/boat/day are
formulated for the region off central California in 1961 to 1963 and
off Oregon in 1967...
