The Social Safety Net and Child Poverty in Oregon

Creator:: Koch, Dillon A.
Abstract:: The Supplemental Poverty Measure (SPM) is the newest method to paint a more accurate picture of the scope of poverty in the United States than the Official Poverty Measure (OPM). In doing so, the SPM includes many sources of income, including income from work and in-kind government supplemental policies. The...

Daily and alternate day supplementation of urea of biuret to ruminants consuming low-quality forage

Creator:: Currier, Thomas A.
Abstract:: Data is limited evaluating infrequent supplementation of urea or biuret to ruminants consuming low-quality forage (<6% crude protein). Therefore, a series of experiments were designed to compare the effects of daily (D) and alternate day (2D) supplementation of two non-protein nitrogen (NPN) sources (urea or biuret) to ruminants consuming low-quality...

Evaluation of perennial ryegrass straw as a forage source for ruminants

Creator:: Fisher, Michael J.
Abstract:: We conducted two experiments evaluating perennial ryegrass straw as a forage source for ruminants. Experiment 1 evaluated digestion and physiological variables in steers offered perennial ryegrass straw containing increasing levels of lolitrem B. Sixteen ruminally cannulated Angus X Hereford steers (231 ± 2 kg BW) were blocked by weight and...

A trace element study of plagioclase and clinopyroxene phenocrysts in historical lavas from Mt. Etna, Sicily, by laser ablation ICP-MS

Creator:: Russo, Christopher J.
Abstract:: Understanding magmatic processes occurring at depth in magmatic systems is fundamental for a more complete understanding of the variations sampled in lavas erupted from these systems on the Earth's surface. This thesis presents the results of detailed trace element analyses of plagioclase and clinopyroxene phenocrysts measured by laser ablation-inductively coupled...

Influence of protein supplementation frequency on cows consuming low-quality forage : performance, grazing behavior, and variation in supplement intake

Creator:: Schauer, Christopher Scott
Abstract:: Our objective was to determine the influence of CP supplementation frequency (SF) on cow performance, grazing time, distance traveled, maximum distance from water, cow distribution, DMI, DM digestibility, harvest efficiency (HE), percentage of supplementation events frequented, and CV for supplement intake for cows grazing low-quality forage. One hundred-twenty pregnant (approx....

Geochemical and helium isotopic variability within the Lau Basin

Creator:: Goddard, Charlotte Ives
Abstract:: This research incorporates geochemical and helium isotopic analyses of Lau Basin volcanic glasses, along with helium isotopic analyses of water column hydrothermal plumes to better understand the processes that control the formation and evolution of this backarc basin. Lavas newly collected from the four southernmost segments of the Valu Fa...

New Metrics, Modeling Applications, and Observational Strategies for Snowpacks in Remote, Data-Limited, Mountain Environments

Creator:: Crumley, Ryan L.
Abstract:: The topics in this dissertation center on the snow processes that dominate mountain environments in the Western U.S. and Alaska, particularly in locations lacking long-term observational datasets or locales that are difficult to access in-person. Some are currently glacierized or have been glaciated in the recent past. Each of the...

New Insights into Mantle Dynamics from Helium Isotopes and Argon Geochronology

Creator:: Konrad, Kevin
Abstract:: Earth’s mantle extends to nearly 3000 km depth, comprises >80 % of Earth’s total volume, and has the largest influence on the primordial and radiogenic heat budget. Despite its importance, the structure and composition of the mantle is still debated. There are three primary models for Earth’s mantle structure that...

Influence of supplement composition on utilization of low-quality, cool-season forages by beef cattle

Creator:: McGuire, Dustin L.
Abstract:: Two studies were conducted to evaluate the influence of supplement composition on intake and digestibility of a low-quality (< 6% CP), cool-season forage, as well as cow performance. Treatments included a non-supplemented control (CON), corn (approximately 8% CP), corn and urea (LU = corn + 0.09 mg/kg BW urea, approximately...

Basaltic volcanism and tectonics of the High Lava Plains, southeastern Oregon

Creator:: Jordan, Brennan T.
Abstract:: The High Lava Plains province (HLP) of southeastern Oregon is a Miocene to Recent volcanic upland characterized by widespread basaltic volcanism and west-migrating rhyolitic volcanism. New ⁴⁰Ar/³⁹Ar ages for HLP rhyolites demonstrate that the trend of migrating rhyolitic volcanism is robust, reflecting westward migration at a rate of -35 km/m.y....
