Nine feeding trials and four laboratory scale experiments were conducted in this study. The study consisted of: (1) use of grass straw:corn juice (CJ) silages with fishmeal and/or alfalfa hay supplementation in beef heifers, sheep, pregnant dairy heifers, water buffaloes and Hereford cows; (2) use of cull onions:grass straw silages...
This research examines two questions: 1) What stories do Christian teacher educators tell about their own White racial identity development? and 2) Is there an impact of studying White racial identity development on the praxis of Christian teacher educators? If so, in what ways? The researcher began the project with...
Stream temperature is a water quality parameter that directly influences
the quality of aquatic habitat, particularly for cold-water species such as Pacific
salmonids. Forest harvesting adjacent to a stream can increase the amount of
solar radiation the stream receives, which can elevate stream temperatures
and impair aquatic habitat. Oregon Forest...
Wheat sharp eyespot (SES), caused by the soil-borne fungus Rhizoctonia cerealis is a common stem disease of wheat globally. The disease caused a severe and extensive epidemic throughout the Willamette Valley of Oregon in 2014 and has remained one of the most important wheat diseases in this region. However, litte...
Lesser quadriceps explosive strength following anterior cruciate ligament (ACL) reconstruction (ACLR) may result in the use of altered landing mechanics that increase the risk for a second ACL injury. Reduced capacity to produce explosive strength in the quadriceps is potentially driven, at least in part, by quadriceps arthrogenic muscle inhibition...
There are presently two successful methods used to refine fish muscle proteins: surimi and fish protein isolate (FPI). Both surimi and FPI have the ability to form an elastic gel upon comminution and heating. However, their gelation behaviors are different as they are refined in a biochemically opposite way based...
Knowledge of post-dispersal seed fates and other regeneration characteristics is
crucial for predicting abundances and distributions of populations and, ultimately,
community species composition and diversity. Seed fate studies, however, are rare
primarily due to the difficulty of determining seed fates and causes of mortality.
This thesis investigated post-dispersal seed fates...
The Fishery Conservation and Management Act of 1976
took effect on March 1, 1977. By this Act the United
States extended its management over fisheries to 200
nautical miles from shore. Extended fishery jurisdiction
was expected to promote industry development and expand
the contribution of the fishing industry to the...
Land use alters the physical and biological structure of stream ecosystems and potentially alters their capacity to process nitrogen (N), an essential nutrient that has nearly doubled in abundance on the biosphere
during the past century from human activities. In this dissertation, I quantified uptake and transformation of nitrate (NO₃⁻)...
