Investigating the ecological role of cell signaling in free-living marine heterotrophic protists

Creator:: Hartz, Aaron J.
Abstract:: Phagotrophic protists are major consumers of microbial biomass in aquatic ecosystems. However, biochemical mechanisms underlying prey recognition and phagocytosis by protists are not well understood. We investigated the potential roles of cell signaling mechanisms in chemosensory response to prey, and in capture of prey cells, by a marine ciliate (Uronema...

Effect of dimethyl sulfoxide on nutrient digestibility

Creator:: Tancred, Barry John
Abstract:: 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....

Methodology for cuticular identification of selected eastern Oregon range plants

Creator:: Schrumpf, Barry J.
Abstract:: 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...

A computer program to solve aqueous inorganic equilibrium systems using Pitzer's method to determine activity coefficients

Creator:: Kelly, Barry
Abstract:: Chemical equilibrium is a major factor in many natural and industrial systems. The ability to predict ionic equilibrium is extremely valuable in industry in solving problems without the costs involved in full scale experiments. An example of an application in the pulp and paper industry is the prediction of non-process...

Symbiotic characteristics of Rhizobium leguminosarum bv. trifolii recovered from nodules of field-grown Trifolium subterraneum L.

Creator:: Wanjagi, Francis Ndung'u
Abstract:: In a series of greenhouse experiments, isolates representing serotypically distinct subpopulations of Rhizobium leguminosarum bv. trifolii recovered from root nodules of field-grown subclover Trifolium subterraneum cv. "Nangeela"), were evaluated for their symbiotic effectiveness potential, their effect on regrowth potential of subclover, and for their competitive abilities to form nodules. Isolates...

Quantification of Copper Speciation in Pulp and Paper Wastewater and Implications for the Biotic Ligand Model

Creator:: Mitzel, Joseph M.
Abstract:: The purpose of this research was to measure the copper-binding behavior of Dissolved Organic Matter (DOM) contained in Pulp and Paper (P&P) wastewater effluent and evaluate the Biotic Ligand Model’s (BLM) ability to quantify copper speciation in P&P influenced waters. A copper ion selective electrode was used to measure copper...

Distribution, habitat associations, and conservation status of Pacific fisher (Pekania pennanti) in Oregon.

Creator:: Barry, Brent R.
Abstract:: Fishers (Pekania pennanti) are medium sized mustelids endemic to North America. Two fisher populations persist in Oregon: an indigenous population in southwestern Oregon, and a reintroduced population in the southern Cascade Mountains. Despite candidacy for listing under the Endangered Species Act, current information on fisher populations in Oregon is scarce....

Thermal energy recovery from large transformers

Creator:: Yao, Barry
Abstract:: This thesis is concerned with designing and simulating waste energy retrieval systems from large transformers to provide heating and cooling of a control house. The transformer selected is Transformer Bank One at the Ross Substation in the BPA system. The unit is an ASEA 250 MVA transformer with forced oil,...

Host preferences of green peach aphid and seasonal occurrence of weed hosts at key sites of aphid buildup

Creator:: Annis, Barry Alan
Abstract:: Green peach aphid and associated weed populations were monitored continuously from April, 1978 to March, 1979 at three orchards and a drainage ditch. Aphid populations at all sites peaked in spring and declined in summer. Although natural enemies were most active during the period of peak aphid abundance, they were...
