All organisms possess circadian clocks, which generate daily oscillations in clock controlled gene expression that regulate many essential biological functions in synchrony with the 24-hour light/dark cycles. When the genes that control the internal clock are weakened, accelerated aging symptoms are observed. Past research in Drosophila demonstrated that aging flies...
This honors undergraduate thesis examines the process of simulating power system state estimation, the use of the alternating direction method of multipliers in the problem of distributed power system state estimation, and provides a rudimentary asynchronous implementation of the above for a linearized DC power system. The asynchronous implementation is...
Exposure to urban outdoor air pollution is ubiquitous and low birth weight represents an important health disparity in the United States. While previous research suggests that exposure to outdoor air pollutants are associated with term low birth weight, few studies have evaluated the effects of multipollutant outdoor air exposures or...
Graphics hardware in mobile devices has become more powerful, allowing rendering techniques such as ray-cast volume rendering to be done at interactive rates. This increase of performance provides desktop capabilities combined with the portability of a tablet. Volumes can demand a high amount of memory in order to be loaded...
Phytophthora cinnamomi Rands is a ubiquitous soilborne pathogen associated with root rot in many woody perennial plant species, including highbush blueberry (Vaccinium corymbosum). To identify genotypes with resistance to the pathogen, cultivars and advanced selections of highbush blueberry were grown in a greenhouse and either inoculated or not with propagules...
Relatively little is known about aboveground nutrient content of organic blackberry, and there is no published work on total carbon (C) content. Treatment effects on biomass, C, and nutrient content, accumulation, and removal were assessed over 2 years in a mature organic trailing blackberry (Rubus L. subgenus Rubus, Watson) production...
Organic production of blackberries is increasing, but there is relatively little known about how production practices affect plant and soil nutrient status. The impact of cultivar (Black Diamond and Marion), weed management (nonweeded, hand-weeded, and weed mat), primocane training time (August and February), and irrigation (throughout the summer and none...
The solid solutions of chlorapatite compounds Ba₅Mn₃−[subscript]xV[subscript]xO₁₂Cl (x = 0–3.0) and Ba₅Mn₃−[subscript]xP[subscript]xO₁₂Cl (x = 0–3.0) have been synthesized through solid state reactions and Pechini or sol–gel method using citric acid. The colors of the samples change from white (x = 3.0) through turquoise (x = 1.5) to dark green (x...
In Weyburn, Saskatchewan, carbon dioxide (CO₂) is injected into the Weyburn oilfield for Enhanced Oil Recovery (EOR). Cenovus Energy Inc. operates more than 1000 active wells, processing plants, and hundreds of kilometres of pipeline infrastructure over a >100 km² area. While vehicle-based atmospheric detection of gas leakage would be convenient...
Purpose: This study examines the relationship between food insecurity (FI) risk and families’ readiness to change obesity-preventing behaviors within rural home-environments.
Methods: Families (n=144) were recruited through six elementary schools (K-5/6) in low-income, rural, Oregon communities. Families completed surveys including a FI risk screener and the Family Stage of Change...
Core-collapse supernovae (CCSNe) are considered to be important contributors to the primitive dust enrichment of the interstellar medium in the high-redshift universe. Theoretical models of dust formation in stellar explosions have so far provided controversial results and a generally poor fit to the observations of dust formation in local supernovae....
Aging is a complex biological phenomenon that alters many different physiological processes. Although many age-related phenotypes, such as neurodegeneration, weakening circadian rhythms, and inflammaging, are well-studied, the links between them are not. To elucidate these links we created an inflammation-like state in Drosophila melanogaster by overexpressing Relish (Rel), an NFκB...
Incoming and graduating engineering students in the School of Chemical, Biological, and Environmental Engineering at Oregon State University were surveyed in order to assess awareness and integration of social responsibilities into their emerging professional persona and how those views are informed by program and faculty interactions. Preliminary analysis of responses...
Historically, Psychology education about disability focused narrowly on psychiatric and cognitive disabilities. Furthermore, disability tends to be viewed from the medical model, rather than the social model endorsed by disability scholars, which describes disability as primarily socially constructed. Course offerings for the Psychology departments of 98 top-ranked undergraduate programs in...
Liquid manure lagoons are known to be sources of odor and environmentally damaging gas emissions. Land application of the manure slurry after storage can lead to detrimental nutrient runoff and leaching. Floating lagoon covers (biocovers) are one option for reducing emissions, but to date they have only been used to...
This study aims to examine how people read and interpret scientific information, and how they respond to graphs and other data. It can be more broadly applied to help patients better understand information and statistics about certain disease conditions, such as cancer risk and diabetes treatment plans. One approach to...
Pandemic influenza viruses modulate proinflammatory responses that can lead to immunopathogenesis. We present an extensive and systematic profiling of lipids, metabolites, and proteins in respiratory compartments of ferrets infected with either 1918 or 2009 human pandemic H1N1 influenza viruses. Integrative analysis of high-throughput omics data with virologic and histopathologic data...
We analyzed the impact of amenity and biodiversity protection as mandated in national forest plans on the implementation of hazardous fuel reduction treatments aimed at protecting the wildland urban interface (WUI) and restoring fire resilient forests. We used simulation modeling to delineate areas on national forests that can potentially transmit...
Silvicultural regimes that aim at an increased stand structural diversity typically promote small-scale heterogeneity in horizontal and vertical structures, e.g. through the creation of gaps. We used terrestrial laser scanning (TLS) to investigate impacts of altered growing conditions on trees adjacent to artificial gaps as compared to responses of trees...
