Whole system perspective : Steelhead, Onchorhynchus mykiss, glutathione s-transferase as a biomarker of chlorpyrifos exposure

Creator:: Pecore, Rachael G.
Abstract:: Organophosphate insecticides may produce sublethal, adverse effects on salmonid growth, reproduction, maturation, swimming, and feeding. Chlorpyrifos, an organophosphate insecticide, was detected by the Oregon Department of Environmental Quality in the Hood River and tributaries during March 1999 at levels exceeding state water quality standards in the range of 0.011-0.482 μg/L....

Temperature Dependence of Cu₃₋xSb₁₋[subscript y]M[subscript y]S₄ (M=Sn,Ge) Resistivity and Thermopower

Creator:: Mutch, Joshua
Abstract:: An experimental apparatus is modified to allow measurements of the Seebeck coefficient and resistivity to be taken simultaneously. This apparatus is designed for bulk and thin film samples between temperatures of 10 K and 300 K. The apparatus is constructed such that these simultaneous measurements do not interfere with each...
Resource Type:: Undergraduate Thesis
Full Text:: Equation 1 above, S is the Seebeck coefficient, σ the electrical conductivity, T the absolute temperature

Wind Energy: An Analysis and Comparison of Wind-Power Development in the United States and Spain

Creator:: Wilhelmsen, Scott
Abstract:: This essay seeks to analyze the wind-power policies of Spain, the United States and the world in order to better understand the past, present and future potentials of the resource. The growing demand for energy, concerns about global warming, and the need for increased energy security encourage societies to embrace...

Neutron Capture Cross Sections of Cadmium Isotopes

Creator:: Gicking, Allison
Abstract:: The neutron capture cross sections of ¹⁰⁶Cd, ¹⁰⁸Cd, ¹¹⁰Cd, ¹¹²Cd, ¹¹⁴Cd and ¹¹⁶Cd were determined in the present project. Four different OSU TRIGA reactor facilities were used to produce redundancy in the results and to measure the thermal cross section and resonance integral separately. When the present values were compared...

Neutron Capture Cross Sections of Selenium Isotopes

Creator:: Dearmon, Howard D.
Abstract:: The thermal cross sections and resonance integrals for neutron capture by ⁷⁴,⁷⁸,⁸⁰,⁸²Se were measured using the same procedure and equipment for all of the isotopes. Uncertainty and absence of accurate previous values for several isotopes introduces a need of measuring these parameters using similar techniques. This was done using OSU’s...

Development, adaptation and testing of remote, non-powered sampling systems fortemporal characterization of hydraulically fractured shale systems

Creator:: Neumann, Kyle
Abstract:: Extraction of natural gas from shale formations using the process of hydraulic fracturing (fracking) requires the use of thousands of cubic meters of fluid. Hydraulic fracturing fluids are pumped under pressure into shale formations, fracturing the shale and releasing pockets of trapped gases. When the pressure in a natural gas...

Carbon Footprint Calculations for Oregon State University and Guadalupe, Cerro Punta, Panama

Creator:: Melendez-Rivera, Kimberly
Abstract:: Greenhouse gases effects are a leading contributor to climate change; reducing harmful effects of these gases is important for future generations. Worldwide, household consumption makes up seventy-two percent of greenhouse gas emissions, followed by government consumption at ten percent, and investments at eighteen percent (Hertwich, 2009). In order to understand...

Effects of gluten composition and molecular weight distribution on the noodle making potential of hard white wheats

Creator:: Ong, Yee-Ling
Abstract:: A set of flour samples with protein content ranging from 9.7 - 13.3 % was used for this study to evaluate the effectiveness of HMW-GS, SEHPLC and mixograph characteristics as screening tools for noodle texture. The sample set had a large variation in HMW-GS composition with Payne score ranging from...

Differences in dry matter production and nitrogen uptake and partitioning among spring wheat (Triticum Aestivum L.) varieties

Creator:: Hitchcock, Todd
Abstract:: Grain protein concentration of wheat is influenced by numerous factors. When determining a wheat variety's ability to produce protein, the plant's ability to uptake and translocate nitrogen is critical. A greenhouse study was conducted to assess differences in nitrogen use among different wheat varieties. The objective was to determine if...

Characterizing novel bacterial isolates that inhibit the growth of gall-forming phytopathogenic bacteria

Creator:: Belcher, Michael S.
Abstract:: Agrobacterium tumefaciens and Rhodococcus fascians are plant pathogenic bacteria that can induce crown and leafy galls on plants, respectively. Infection by these bacteria results in disfigured, unsellable plants, leading to significant economic losses to the nursery industry. A. tumefaciens and R. fascians are capable of infecting a broad range of...
