Animal dietary preferences have been studied by feeding-site
examinations, animal observation, and stomach and esophageal collections.
Analysis of fecal material for undigested plant cuticle is
another means for obtaining the same information.
This study was conducted to: (1) prepare a microscope slide
series depicting the surface features of leaves and...
Workers with dimethyl sulfoxide (DMSO) in the
United States and England have reported in the literature
that the chemical affects the weight gaining ability of
experimental animals. Narula, University of Oregon
Medical School, Portland, found that 50 parts per million
DMSO increased the size and numbers of tissue culture
cells....
Effects of light intensity, exposure to desiccation, reduced
salinity, and thermal elevation on the functional and structural characteristics
of marine benthic diatom communities were investigated
in a laboratory model ecosystem and a respirometer chamber.
Measurements of biomass (dry weight and ash-free dry weight)
and chlorophyll a were made for each...
Quantitative and qualitative information on the retention of chlorinated residues in chloropicrin treated wood is lacking. Retention of chloropicrin and its chemical breakdown products in wood, and the effects of chloropicrin treatment of wood on invading decay fungi are explored in this thesis. Chlorinated residues in amounts up to 1.5%...
An algorithm for computing the parameter sensitivities of an excitation system for a hydroelectric generation system is developed for model analysis in this thesis. The IEEE Type 1 excitation system representation, linked with a simplified alternator and voltage regulator equivalent, provide a closed-loop model for digital simulation. Parametric sensitivities are...
In the event of a small break loss of coolant accident
(SBLOCA) in a nuclear reactor, cold fluid is injected through
the reactor system high pressure injector to compensate for
the coolant loss. When this flow rate is less than a critical
value, however, the hot fluid in the cold...
Ninety basalt samples from eight locations in central Oregon
and one location in the Willamette Valley were analyzed for Si and Al.
Fourteen basaltic rock specimens (> 1 kg each) from four buttes in the
Willamette Valley were sampled and analyzed for Si, Al, Fe, Na, K,
Mn, Cr, Co,...
The purpose of this study is to critically explore low-income women's experience as they negotiate post secondary education in community colleges. Three research questions explore the context through which low-income women have entered the college experience, what that experience is like for them, and how the community college experience has...
