  • Target fragmentation in the interaction of relativistic heavy ions and protons with ¹⁸¹Ta

    Creator:
    Oertel, Christopher Paul
    Abstract:
    The production cross sections for a number of target fragments formed by the reactions of 42- and 21- GeV²⁰ Ne and 28 GeV p with ¹⁸¹Ta have been measured. The target fragment radioactivities were measured by off-line gamma-ray spectroscopy. Details of the measurement as well as the calculation of the...

  • Thresholds of uncertainty : radiation and responsibility in the fallout controversy

    Creator:
    Jolly, J. Christopher
    Abstract:
    The public controversy over possible health hazards from radioactive fallout from atomic bomb testing began in 1954, shortly after a thermonuclear test by the United States spread fallout world wide. In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...

  • Stereoselective synthesis & application of enantioenriched main group α-haloalkyl organometal reagents

    Creator:
    Emerson, Christopher R.
    Abstract:
    Sulfoxide-ligand exchange (SLE) and asymmetric halogen-metal exchange (AHME) processes were separately examined for the enantioselective synthesis of functionalized alpha-haloalkylmetal (carbenoid) reagents. Carbenoids derived from SLE were used to effect stereospecific reagent-controlled homologation (StReCH) of boronic esters and those generated via AHME were engaged in Darzens-type chemistry with aldehydes. Abstract for...

  • The Deathscape of St. Paul: Historic Cemeteries as Cultural Landscapes

    Creator:
    Boulware, Brooke L.
    Abstract:
    A cultural landscape analysis of two historic cemeteries in St. Paul, Oregon demonstrates that the residents of this early community were unknowingly using grave markers to express their worldview and the identities that they felt were most important. Because of the historical and cultural development of this community as the...

  • Identification of candidate genes for survival and their use in predicting field performance of Pacific oyster Crassostrea gigas families in coastal waters

    Creator:
    Lang, Robert Paul
    Abstract:
    Summer mortality of farmed Pacific oysters causes financial losses for shellfish growers, and selective breeding to improve survival of offspring is a promising way to reduce losses. This dissertation has two objectives to assist the development of tools for use in selective breeding programs. Objective 1: Identify candidate genes for...

  • The effects of nutrition on the zinc sensitivity of Mysidopsis intii

    Creator:
    Vance, Paul Mitchell
    Abstract:
    A static-renewal, seven day test was developed and utilized to study the effects of nutrition on the sensitivity of Mysidopsis intii Holmquist to zinc. It was found that juvenile growth was the most reliable and sensitive endpoint that could also reflect the subtle effects of low zinc concentrations and diet...

  • Conformationally chiral diphenylethers and the enantioselective Ullmann etherification

    Creator:
    Salih, M. Quamar
    Abstract:
    Since the discovery of molecular chirality in 1848, this notion has had a substantial impact on medicine, biology, and chemistry. Extensive effort has been directed towards the construction of chiral molecules that contain sp³ hybridized stereogenic centers. In contrast, less effort has been dedicated to molecules that are chiral by...

  • Biochemical effects of tumorigenic enhancers

    Creator:
    Christopher, John Paul
    Abstract:
    2 -acetylaminofluorene -induced hepatocarcinogenesis in rats proceeds in stages of initiation and promotion, similar to experimental systems, in mouse skin. In this study promoters of liver tumorigenesis, phenobarbital, DDT and butylated hydroxytoluene (BHT), were compared to non-promoters, amobarbital, diphenylhydantoin (DPH) and benz(a)anthracene (BA), for their ability to cause liver growth...

  • Habitat associations and life histories of odonata in riverine wetlands of the Willamette Valley, Oregon

    Creator:
    Beatty, Christopher D.
    Abstract:
    This thesis explored the distributions and life histories of dragonflies and damselflies (Insecta: Odonata) of the riverine wetlands of the Willamette Valley in western Oregon, USA. Odonate species distributions were characterized over two seasons in the autumn of 2000 and the spring of 2001-at twenty-seven wetlands located throughout the valley....

  • Total Synthesis of Tryptamine Alkaloids from the Arundo and Leuconotis Genera

    Creator:
    Ferreira, Andrew
    Abstract:
    The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...
