Regional scale sandbar variability : observations from the U.S. Pacific Northwest

Creator:: Di Leonardo, Diana R.
Abstract:: Understanding sandbar dynamics and variability is integral to developing a predictive capacity for nearshore flows, sediment transport, morphological change, and ultimately for determining coastline exposure to damaging storm waves. Along the high-energy U.S. Pacific Northwest (PNW) coast, sandbars typically dominate the bathymetry of the active zone. Here we report on...

The bioavailability of vitamin B₆ from selected foods as measured by urinary 4-pyridoxic acid in men saturated with pyridoxine

Creator:: Lozano de Gonzalez, Patricia
Abstract:: The bioavailability of vitamin B₆ in four selected foods (bananas, filberts, soybeans and beef) was determined in five men, aged 22 to 25 years, who were saturated with pyridoxine. The study consisted of a five-day adjustment period followed by a 28-day experimental period. All subjects consumed a constant diet containing...

A mechanized harvesting system simulation : input, output, limitations and capabilities

Creator:: Aedo-Ortiz, Dario M.
Abstract:: This study concerns the use of a discrete-event simulation model for analyzing the production of a mechanized forest harvest system. The simulation models a field collection data set of a harvester-forwarder system which was previously collected by the Forest Engineering Department of Oregon State University. The computer software consisted of...

Region-Specific Investigation of the Cone Penetration Test for Preliminary Classification and Estimation of Preconsolidation Stress, Undrained Shear Strength, and Cyclic Resistance of Transitional Silts

Creator:: Ortiz, Susan Christine
Abstract:: The Cone Penetration Test (CPT) has been widely-adopted for rapid, cost-effective exploration of the subsurface and reduction in the effort associated with drilling, sampling, and laboratory testing of soil. The adoption of the CPT has stemmed in part to the correlation of measurements to preliminary soil classification, stress history, drained...

Plant community recovery after high severity wildfire and post-fire management in the Klamath Region

Creator:: Lopez Ortiz, Maria Jose
Abstract:: Disturbance and microclimate interact to play a central role influencing the composition and structure of plant communities. In this thesis, I examined plant community composition and structure twenty years after high severity wildfires with and without post-fire management (salvage logging, fuel treatment, tree planting, and shrub release) under contrasting microclimatic...

Removal of E. coli with alternative media Biosand filters

Creator:: Fulton, Nathan J.
Abstract:: When Biosand filters cannot be constructed with crushed quarry rock due to resource limitations, a suitable alternative filter media is needed. In this research, two crushed quarry rock alternatives were examined. Three bench-scale Biosand filters with crushed rock, beach sand, and heat-treated beach sand media were simultaneously dosed with Willamette...

Perceptions of Mattering for Black Male Student-Athletes in Revenue-Producing Sport

Creator:: Kuiken, Christina
Abstract:: Black male student-athletes in revenue-producing sports encounter multiple stressors at predominantly White institutions (PWI). These stressors can include identity conflicts, role confusion, feelings of exploitation as revenue producers, academic imposter syndrome, heavy workloads, and racial microaggressions. This study explores how Black male student-athletes in revenue-producing sports define their roles within...

Deformation imaging

Creator:: Margiocco, Marco L.
Abstract:: Recent developments in the field of clinical echocardiography allow the ultrasonographer to objectively quantify both regional and global myocardial function. Regional deformation (Strain) and deformation rate (Strain Rate) are novel indices of ventricular function that can be estimated non-invasively by ultrasonographic interrogation of the heart. Deformation Imaging (DI)represents a family...

Post-fire Forest Management Activities Alter Soil Properties, Sediment Yields, and Vegetation Recovery in the Northern California Coast Range

Creator:: Cole, Ryan P.
Abstract:: The extent and severity of wildfires in forested regions are increasing throughout many regions on the planet, including western North America. High-severity wildfires directly affect soils and vegetation by altering soil hydraulic properties, reducing soil organic matter, exporting carbon and nitrogen, and killing trees and understory vegetation. These impacts can...

Metabolic uncoupling of Shewanella oneidensis MR-1, under the presence of excess substrate and 3,3’,4’,5 tetrachlorosalicylanilide

Creator:: Saini, Gaurav
Abstract:: Dissociation between catabolism and anabolism, generically termed “metabolic uncoupling”, has been studied for aerobic cultures of Shewanella oneidensis MR-1. Under conditions promoting metabolic uncoupling, the cell yield diminishes while the substrate utilization rate remains largely unchanged. The effects of excess substrate conditions and TCS addition on the metabolism of pyruvate...
