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....

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...

Invest in Vegetables: A Cost and Benefit Analysis of Container Grown Roma Tomatoes (Solanum lycopersicum cv. ‘Roma’) and Italian Basil (Ocimum basilicum cv. ‘Italian’)

Creator:: Spofford, Tyler S.
Abstract:: The COVID-19 pandemic highlighted disparities in land access and food security. Research has shown that access to gardening reduces financial burdens on low-income households. Compared to homeowners, individuals and families in rental housing face added barriers to vegetable gardening and growing food. These barriers include rental housing regulations and the...

Potential of eradicating noxious weed seeds from the soil with heat and carabid seed predators

Creator:: Marshall, Nicole S.
Abstract:: The goal of this project was to develop and test non-herbicidal techniques that remove nonnative plant or weed seeds from the top 2 inches of the soil. The Nature Conservancy (TNC) is currently restoring prairies in the Willamette Valley. Some areas of the Pacific Northwest have already seen loss of...

Overview of the Comparison of Commercial Pelagic Species Fisheries Management in Malaysia and Oregon, United States

Creator:: Ahmad, Amir
Abstract:: The United Nations Food and Agriculture Organization (FAO) in the State of World Fisheries and Aquaculture 2018, has observed that the trend of the world’s marine fish stocks has been overexploited, depleted, and has exhibited decreasing trend within the fraction of biologically sustainable levels. While these situations are an alarming...

A reassessment of the linkage of red leaf trait and incompatibility loci in hazelnut (Corylus avellana L.)

Creator:: Horton, G.
Abstract:: As in other species, it is possible that a homozygous red leafed (= redleaf) hazelnut (Corylus avellana L.) tree would have brighter red coloration than a heterozygote and thus be more desirable as an ornamental. However, 'Fusco Rubra' and `Rode Zeller' both carry incompatibility allele S6 (thus cross-incompatible) and are...
