Sampling with seine and trawl from May 1974 to November 1976 indicated that the species composition and distribution of fishes in Tillamook Bay through time is primarily related to the movements of marine species in and out of the estuary. Northern anchovy (Engraulis mordax), surf smelt (Hypomesus pretiosus), and shiner...
The two major purposes of this study were: (1) to test the
assumption that the IT Scale for Children (standard-ITSC) can be used
as a measure of both appropriate sex role discrimination and sex role
preference with preschool aged children, and (2) to extend previous
studies in these areas by...
The studies described in this thesis were motivated by ongoing efforts to develop lignocellulosic biomass as an efficient and practical source of renewable energy. Enormous problems complicate these efforts to reduce reliance on greenhouse gas-generating fossil fuels. Simply obtaining the fermentable sugars available in the cellulose and hemicellulose components of...
The effect of gadolinia particles on the assembly criticality
of a light water reactor was investigated using two 2-group
models. The particle effect was calculated by comparing the
criticalities of two fuel assemblies, each containing one
gadolinia-poisoned rod. For purposes of comparison, both rods
contained an equal quantity of gadolinia,...
Reductive sulfate assimilation, the biological process by which sulfur-containing amino acids and key derivatives are synthesized from sulfate, is broadly shared among bacteria, fungi, and plants. It is the major, if not sole source of methionine and cysteine for Saccharomyces cerevisiae during wine fermentation. Two obligate intermediates formed in the...
