The development of new technologies in science is a balance between existence and use. There are three versions of this duality – something is built and users come, something is built and users don’t come, and, finally, potential users show up but the ballpark has not yet been built. In...
Behavior and survival in fresh water were studied for three brood years of coho salmon in Sashin Creek, Alaska, from October 1963, until September 1966. Investigations of spawning adults were conducted to determine numbers of spawners, distribution on the spawning grounds, effects on pink salmon, age composition, redd life, fecundities,...
Restriction of long-distance movement of several potyviruses in Arabidopsis (Arabidopsis thaliana) is controlled by at least three
dominant restricted TEV movement (RTM) genes, named RTM1, RTM2, and RTM3. RTM1 encodes a protein belonging to the
jacalin family, and RTM2 encodes a protein that has similarities to small heat shock proteins....
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...
A taxonomic revision of the genus Anthracobia Boudier is
presented. The genus and eight included taxa are described and
figured. A discussion of the taxonomic criteria used to delimit the
genus and the species is included, and a key to the recognized taxa is
given. Four imperfect states for included...
This thesis was to develop a bone artifact typology for the Oregon coast. This typology was used to test the hypothesis that different geographical regions of the Oregon coast would have different artifact assemblages associated with them. These regions, identified by geologist from landform changes, have been defined as: region...
The purpose of this study was to describe women's outdoor garments worn in Oregon from 1880 to 1920 to determine whether there were garment differences between the Willamette Valley and Eastern Oregon. The question addressed was: can garment differences be explained by the different Oregon climates, geographic locations, and availability...
The regular monitoring of evapotranspiration from satellites has been limited because of discontinuous temporal coverage, resulting in snapshots at a particular point in space and time. We developed a temporal upscaling scheme using satellite-derived instantaneous estimates of evapotranspiration to produce a daily-sum evapotranspiration averaged over an 8-day interval. We tested...
The immune system is a complex network of cellular processes working in harmony to guard us against pathogenic attack. Of utmost importance is the ability of the immune system to discriminate between “self” and “non-self” and diseased versus healthy. Recognition of antigens complexed to major histocompatibility complex (MHC) molecules is...
There is a national interest in improving the quality of science, technology, engineering, and mathematics (STEM) education in institutions of higher education in the face of mounting difficulties. Reports by the National Academy of Sciences in 2018 and 2020 found that the dissemination and adoption of effective, timely change initiatives...

has been interest in astronomy in this country. The purpose of this
thesis is to show how the science of astronomy developed in America
from the earliest observations by educated colonists using imported
instruments and publishing in European journals, to...
Chlamydia is an obligate intracellular bacterial pathogen that causes a variety of disease in animals and humans worldwide. Veterinary chlamydial pathogens can lead to chronic infections and serious consequences that result in millions of dollars of losses in animals and resources in the agricultural industry in countries that rear ruminants....
The overall focus of this thesis is on the distribution of specific lipids and membrane proteins of the external and internal membranes of plant cells, in the context of the roles that those lipids and proteins may play in microbe-plant interactions. The work includes the development of several new tools,...
Public policy narratives and stories are often referenced by the media, politicians, advocacy groups, and across many disciplines in academia. Studies of social and political narratives support the notion narrative matters, but often lack systematic design capable of producing generalizable findings. The Narrative Policy Framework (NPF) has responded to this...
Research progress to understand the role of vitamin C (ascorbic acid) in human health has been slow in coming. This is predominantly the result of several flawed approaches to study design, often lacking a full appreciation of the redox chemistry and biology of ascorbic acid. In this review, we summarize...
The emerging field of nanotechnology strictly requires the micro-scaling of the available separation technology and the design of novel devices for separations of molecules of interest. The separation of proteins and nanoparticles is challenging due to their relatively large size, non-specific adherence to surfaces and instability in many solvents.
This...
Intimate associations with reactive metal species permanently protect soil organic matter (SOM) from microbial access and oxidation, contributing to the build-up of organic carbon (C) stocks in soils. It is increasingly recognized, however, that such associations can be reversible and that reactive metal species might even facilitate the oxidation of...
The majority of teachers in the state of Oregon are White, prompting the state’s legislative bodies to explore and create ways to increase racial diversity in the profession. Contextually, both state level mandates and national accreditation bodies have attempted to address the lack of diversity amongst teachers in the K-12...
Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...
Observed declines in native pollinator species worldwide has generated concern and focused research into the disturbances, past and present, which may have contributed to these losses. In grasslands, for example, habitat degradation and fragmentation from historical and current crop production and livestock grazing has left only a few remnants of...
The fungus Fusarium fujikuroi causes "bakanae" disease of rice due to its ability to produce gibberellins (GAs), but it is also known for producing harmful mycotoxins. However, the genetic capacity for the whole arsenal of natural compounds and their role in the fungus' interaction with rice remained unknown. Here, we...
The demand for biofuels continues to increase due in part to government standards and promotion as well as the ambitious goals set by various companies and industries. Camelina is considered to be an ideal energy crop because of its low input requirements, suitability for marginal soils, and naturally competitiveness with...
This dissertation examines the impact of the German naturalist and literary figure Johann Wolfgang von Goethe’s ideas on twentieth century Anglophone plant morphology and biology. Goethe interpreted the organ forms of flowering plants as metamorphoses of each other. His literary, historical, and philosophical writings suggest themes of alienation from and...
The relationship of intracellular drug levels and resultant drug activity to intracellular pH (pHi) was studied in the experimental tumors. Glucose (5 g/kg) and/or sodium oxamate (0.1 mmol) were administered to Walker 256 ascites cells and Ehrlich ascites cells, in an attempt to alter pHi as measured by the distribution...
