Cephalosporium stripe of wheat (Triticum aestivum),
caused by the soilborne fungus Cephalosporium gramineum,
results in significant yield reductions in dryland winter
wheat crops of the U.S. Pacific Northwest. The
development of resistant cultivars offers the best hope
for disease control. Breeding for resistance is hampered
by the long trial times...
Pacific whiting (Merluccius productus) is one of the most abundant fisheries on the American west coast. However, these fish are historically underutilized due to quality issues resulting from fillet softening that occurs as a result of both endogenous and exogenous (Myxosporidian parasite infection) cathepsin protease action during either storage (cathepsin...
The scientific method applies hypothesis testing to material samples through experimentation, measurement, and data analysis, which produce representations—or features—that describe phenomena of interest. Biomolecular features come in numerous forms such as values, matrices, graphs, three-dimensional structures, trajectories, and molecular surfaces. Researchers have tested thousands of features related to protein molecules...
This thesis involves analyses of 3₂-helices, a-helices and of the change in residual
entropy of a protein upon chemical modification. Part of the long-term goal of
understanding the formation, function and stability of proteins requires that all
conformations be accurately assigned and structurally understood. By a statistical
analysis of 258...
The solution structure determination of DNA molecules has been an important part of structural biology. NMR solution structures are a complement to structures solved via X-ray crystallography; the two methods are the only ways of obtaining three dimensional coordinates of macromolecules. Because of the nature of the molecule, the solution...
Providing transformational learning opportunities for undergraduate students demands changes to teaching practices. In large-enrollment introductory courses, graduate teaching assistants (GTAs) play an important role in facilitating student learning in small group environments. However GTAs are not provided the pedagogical development necessary to support them to be effective in their teaching...
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...
The in-line force power spectrum is predicted by the frequency domain maximum force coefficient [C[subscript μn](z,f[subscript n])] vs. Keulegan-Carpenter number [K[subscript n] (z,f[subscript n])] relationship. The frequency domain Keulegan- Carpenter number is defined as the velocity from the amplitude spectrum at f divided by the respective frequency and diameter of...
Headwater streams in the Oregon Coastal Range are subject to drastic fluctuations in flow and temperature because of the changing seasonality of a Mediterranean climate. In response to these changes, stream fishes exhibit a variety of movement patterns. Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) have evolved an assortment of life...
Globally, as surface water quality and quantity diminishes there is increasing reliance on groundwater to buffer water demands of growing populations. Today in many arid regions around the world aquifer pumping rates far exceed recharge rates. Often the groundwater is nonrenewable, or thousands of years old. Despite the known hydrologic...
