  • Metabolism of toxic plant alkaloids in livestock : comparative studies on the hepatic metabolism of pyrrolizidine alkaloids in sheep and cattle and of ergot alkaloids in an endophyte-resistant mouse model

    Creator:
    Duringer, Jennifer Marie
    Abstract:
    The pyrrolizidine alkaloids (PAs) and ergot alkaloids are known natural toxicants found in livestock forage. These alkaloids contribute to large economic losses in livestock throughout the world. An understanding of the mechanisms of toxicity and development of better diagnostic tools for better management practices was investigated. Variability exists in the...

  • A Preliminary Archaeological Predictive Model for the US 30 Transportation Corridor, Portland, Oregon to Astoria, Oregon

    Creator:
    Kachadoorian, Lydia A.
    Abstract:
    This thesis is a preliminary archaeological predictive model and project-planning tool created for the Oregon Department of Transportation (ODOT) as part of a statewide planning effort to enhance the agency's ability to assess the potential impacts of highway projects on archaeological resources. This model addresses the archaeological sensitivity of the...

  • A Qualitative Study of Women in Modern Day Polygamous Households in the United States

    Creator:
    Wilson, Suzanne M.
    Abstract:
    This study will show that polygamy is not a religious freedom protected under the U.S. Constitution, but a power system in which men use economic, political, social and physical force to control the behavior of others. This thesis will use a feminist perspective theory to provide a theoretical outline for...

    Creator:
    Dietz, Amy L.
    Abstract:
    A memoir is variously defined as an abbreviated autobiography; a record of events based on the writer's personal observation or knowledge; and the written story of one's own life. I set out to do those things. But when I sat back to read the first of many drafts, I discovered...

  • Studies of non-mevalonate isoprenoid biosynthesis : the 1-deoxy-D-xylulose-5-phosphate isomeroreductase (DXR) mediated reaction

    Creator:
    Woo, Youn-Hi
    Abstract:
    This dissertation details the investigation of an alternate pathway to isoprenoids that occurs in plants and microorganisms, the non-mevalonate pathway. This exploration of the pathway focuses on the second step, the conversion of 1-deoxy-D-xylulose-5-phosphate (DXP) to 2-C-methylerythritol-4-phosphate (MEP) by the enzyme DXP isomeroreductase (DXR). These studies led to an appreciation...

  • Fabrication and characterization of p-type CuO / n-type ZnO heterostructure gas sensors prepared by sol-gel processing techniques

    Creator:
    Ravichandran, Ram
    Abstract:
    Increased interest in the field of sensor technology stems from the availability of an inexpensive and robust sensor to detect and quantify the presence of a specific gas. Bulk p-CuO/n-ZnO heterocontact based gas sensors have been shown to exhibit the necessary sensitivity and selectivity characteristics, however, low interfacial CuO/ZnO contact...

  • Studies on isoprenoid biosynthesis in Euglena gracilis

    Creator:
    Kim, Dojung
    Abstract:
    This dissertation describes studies of isoprenoid biosynthesis in the phytoflagellate Euglena gracilis. Elucidation of a novel isoprerioid pathway, the 2-Cmethyl-D-erythritol-4-phosphate (MEP) pathway, in addition to the generally known mevalonate (MVA) pathway, led to extensive exploration of the distribution of both pathways in a variety of organisms. To date, photosynthetic eukaryotes...
