Metabolism of pyrrolizidine alkaloids by ruminal microbes

Creator:: Hovermale, Jeannette Talbot
Abstract:: The plant Senecio jacobaea (tansy ragwort) produces several macrocyclic pyrrolizidine alkaloids which cause irreversible liver cirrhosis. All of the pyrrolizidine alkaloids in Senecio jacobaea are macrocyclic diesters of the necine base retronecine, with the two most predominant being seneciphylline and jacobine. Unlike horses and cattle, sheep and goats are generally...

Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....

A Wireless Energy Harvester for Powering Event-driven Internet-of-things Applications and Battery Charging

Creator:: Sadagopan, Kamala Raghavan
Abstract:: The need for sustainably powering unobtrusive internet-of-things applications has led to an interest in energy harvesting. Particularly, the proliferation of wireless communication and devices in the 2.4 GHz Industrial Scientificc Medical (ISM) band creates an opportunity to leverage commonly used devices for RF powering. This dissertation presents a low-quiescent-power...

Posttraumatic Growth, the Physically Active Body, and Self-Compassion

Creator:: Mitchell, Erin E.
Abstract:: Individuals who have been traumatized have the opportunity to experience posttraumatic growth, conceptualized as positive changes that result from navigating highly challenging life circumstances (Tedeschi & Calhoun, 2004). The current model of posttraumatic growth (Calhoun, Cann, & Tedeschi, 2010) is based solely on cognitive-emotional processing yet by examining the role...

Brassicaceae Seed Persistence and Dormancy in the Willamette Valley

Creator:: Flick, Gabriel D.
Abstract:: Producers in the Willamette Valley of Oregon are interested in growing canola as a rotational crop in grass seed and cereal rotations. Many other Brassicaceae seed crops also are produced within the valley. Concerns of seed persistence and volunteer contamination of Brassicaceae seed crops prompted the investigation of seed persistence...

Ruminant and microbial physio-chemical response to abrupt ration changes as influenced by chemical and/or biological means

Creator:: Patton, Westley R.
Abstract:: Three trials with wethers and four trials with steers were conducted to determine some of the effects of sodium bicarbonate, calcium hydroxide and/or transfer of ruminal contents on ruminant adjustment to abrupt changes to concentrate rations. Lambs fed a basal concentrate diet plus sodium bicarbonate had the highest average feed...

ALS-inhibitor resistant downy brome (Bromus tectorum L.) biotypes in Oregon : Mechanism of resistance, fitness, and competition

Creator:: Park, Kee-Woong
Abstract:: Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...

Insights into Centennial-Scale Salt Marsh Morphodynamics from the Oregon Coast

Creator:: Peck, Erin K.
Abstract:: Quantification and comparison of morphological changes over the last ~300 y in Oregon salt marshes provide valuable insights into the tectonic, hydroclimatic, and anthropogenic processes shaping this important intertidal zone. Understanding of the rates and drivers of salt marsh change contextualizes intertidal habitats within the sediment routing system (i.e., source...
