A Low-Volume Flow-Through System for Rearing Pacific Oyster (Crassostrea gigas) Larvae

Creator:: Fleener, Henry R.
Abstract:: Standard larval Pacific oyster (Crassostrea gigas) rearing systems can be described as either static or continuous flow. While rearing oyster larvae in static cultures can be a low-cost and simple method, static systems require significant husbandry effort, floorspace and can produce highly variable results due to environmental variance among cultures....

Acceleration of Long-Range Ordering in NiCrFe Alloys Via Proton Irradiation

Creator:: Evered, Cole E.
Abstract:: This work explores the hypothesis that proton irradiation is a feasible alternative to simulate accelerated thermal aging for Ni2Cr long-range ordered phase formation within NiCr and NiCrFe alloys. In this study, various model alloys and commercial alloys 690 and 690+P (0.01 wt.% P) were subject to 2 MeV proton irradiation...

The Development of a Hybrid Particle-in-Cell Simulation Code in C++ for the Modeling of the SPT-70 Hall Thruster

Creator:: Myers, Conner J.
Abstract:: In order to support the growing satellite propulsion industry, a hybrid Particle-In-Cell (PIC) simulation with fluid treatment of electrons and neutral particles was developed to model the SPT-70 Hall thruster. The 2D, C++ code assumes azimuthal symmetry and a uniform magnetic field in the radial direction with the simulation domain...

Evaluation of Pacific Lamprey Entosphenus Tridentatus Anatomical Structures as Records of Age and Isotope Histories

Creator:: Pelekai, Keala N.
Abstract:: The anadromous Pacific Lamprey (Entosphenus tridentatus) is a biologically and culturally important species native to the North Pacific Ocean and its adjacent freshwater tributaries. Pacific Lamprey have experienced declines in abundance and distribution throughout their native range, highlighting a need for further research on the species to better inform conservation...

Organic Pelletized Chicken Manure Application Rates and Effects on Novel Asian Vegetables in the Willamette Valley

Creator:: Velazquez, Hannah D.
Abstract:: Daikon, mizuna, mizspoona, and komatsuna are novel Asian vegetables for which a market exists in Oregon, especially in the organic sector. However, these crops are currently not grown widely in the area, despite the favorable growing environment of Oregon’s Willamette Valley. Little is known about the appropriate application level of...

Examining the Effects of Artisanal, Small-scale Gold Mining on Livelihood Assets in Kedougou, Senegal

Creator:: Zoch, Grant L.
Abstract:: The frontlines of climate change adaptation will occur in rural, impoverished regions of the world where households engage in climatically dependent livelihoods, such as peasant agriculture or pastoralism. As changing climate and changing markets affect the suite of household livelihood assets (environmental, social, and economic) which enable a household to...

Vulnerability and adaptation of Pacific Northwest shellfisheries to ocean acidification

Creator:: Katz, Brian G.
Abstract:: The purpose of this study was to understand the vulnerability and adaptive capacity of shellfish stakeholders in the Pacific Northwest who are adapting to ocean acidification (OA). This study developed a geovisualization tool of existing environmental data for assessing species-specific risk profiles to OA (based on their exposure and sensitivity),...

The Effects of Structure and Volcanic Stratigraphy on Groundwater and Surface Water Flow: the Hat Creek basin Case Study, California, USA

Creator:: Marcelli, Marina F.
Abstract:: Hydrogeologic systems in the southern Cascade Range develop in volcanic rocks where volcanic morphology, stratigraphy, extensional structures and attendant basin geometry play a central role in groundwater-flow paths, groundwater/surface-water interactions, and spring discharge locations. High-volume springs (> 3 m3/s) flow from young (< 1 Ma) volcanic rocks in the Hat...

Monotonic and Cyclic Testing of Cross-Laminated Timber Diaphragms

Creator:: Beairsto, Cody J.
Abstract:: Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete. Large, in-plane tests on cross-laminated timber...

Evaluating the Effect of Emotions on Student Learning using Prescriptive and Open-ended Lab Activities for a Lean Manufacturing Engineering Course

Creator:: Perez, Maritza
Abstract:: Research has shown that emotional connections during lab activities increase learning in chemistry and physics courses. However, little research has examined the effects of emotion in engineering courses, and these studies have recognized a dearth of research examining the ability of students to apply engineering concepts in real-world applications based...
