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...

Impact of Vitamin E Deficiency on Hepatic Gene Expression of CRAL_TRIO Family Proteins in a Premier Vertebrate Animal Model

Creator:: Watt, Alexander T.
Abstract:: Vitamin E (vitE) is a group of lipid-soluble antioxidants- of which alpha-tocopherol is the most biologically active and only form considered to be an essential nutrient. Through preferential binding and trafficking, the alpha-tocopherol transfer protein (α-TTP) regulates the concentration of vitE in the body. The impact of vitE deficiency on...

Investigating synergistic effects of climate and land-use change on the pollination of a tropical plant, Heliconia tortuosa

Creator:: Dowd, Claire E.
Abstract:: Loss of biodiversity due to the effects of climate and land-use change may have implications for pollination services. Disruption to phenological synchronicity or a reduction in the overlap in species distributions of plants and their pollinators may reduce floral resources to pollinators, forcing them to move farther distances. If pollinators...

Women's Health Narratives: A Cervical Cancer Prevention Program for College-Age Women in Portland, Oregon

Creator:: Sawtelle, Katie G.
Abstract:: Human Papillomavirus (HPV) is so common that about 80% of those in the United States will acquire it during their lifetime. In more serious cases, HPV can develop into cancer: each year in the U.S., there are around 32,000 HPV related cancer diagnoses. The HPV vaccine series can prevent the...

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),...

Mutagenic Analysis of Victorin Sensitivity in Arabidopsis thaliana and Avena sativa

Creator:: Seshadri, Rishi S.
Abstract:: The fungal pathogen Cochliobolus victoriae, the causal agent of Victoria blight, produces a host-selective pathogenicity factor called victorin. In Arabidopsis thaliana, a dominant gene called "supersense" (SSN) confers constitutive victorin sensitivity at very low concentrations. SSN encodes a nucleotide-binding leucine-rich-repeat (NB-LRR) protein. In the SSN-carrying Heiligkreuztal 2 ecotype (TAIR Germplasm...

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....

Leaf-level physiology in four subalpine plants in tephra-impacted forests during drought

Creator:: Watt, Abby J., Fischer, Dylan G., Antos, Joseph A., and Zobel, Donald B.
Abstract:: Ecological impacts of climate change in the Pacific Northwest may hinge on acclimation to drier summers, highlighting the importance of plant physiological studies in forests. Evaluating dominant forest plant species under old-growth and managed forest conditions is similarly important as timber harvest might change microclimates and alter drought effects on...

Wild bee diversity is enhanced by experimental removal of timber harvest residue within intensively managed conifer forest

Creator:: Rivers, James W., Mathis, Codey L., Moldenke, Andrew R., and Betts, Matthew G.
Abstract:: The use of timber harvest residue as an energy source is thought to have environmental benefits relative to food-based crops, yet the ecological impact of this practice remains largely unknown. We assessed whether the abundance and diversity of wild bees (Apoidea) were influenced by the removal of harvest residue and...

Validation of IMERG Precipitation in Africa

Creator:: Dezfuli, Amin K., Ichoku, Charles M., Huffman, George J., Mohr, Karen I., Selker, John S., van de Giesen, Nick, Hochreutener, Rebecca, and Annor, Frank O.
Abstract:: Understanding of hydroclimatic processes in Africa has been hindered by the lack of in situ precipitation measurements. Satellite-based observations, in particular, the TRMM Multisatellite Precipitation Analysis (TMPA) have been pivotal to filling this void. The recently released Integrated Multisatellite Retrievals for GPM (IMERG) project aims to continue the legacy of...
