  • Using Spatial Capture-Recapture to Estimate Density of Roosevelt Elk in Western Oregon

    Creator:
    Nelson, Jennifer E.
    Abstract:
    Spatial capture-recapture (SCR) is employed for estimating abundance and density of species, particularly those that are cryptic or solitary, and evaluating how population density varies with habitat. However, it is uncertain whether estimates are biased when applied to species that aggregate, such as elk (Cervus canadensis). Wildlife managers in the...

  • Top-down scaling analysis of the integral reactor vessel test facility

    Creator:
    Graves, Joshua D.
    Abstract:
    Oregon State University has conducted research in collaboration with TerraPower, LLC, to perform a top-down scaling analysis of an integrated test facility. The goal of this facility is to simulate transient and quasi-steady phenomena at a reduced scale, including steady-state operation, pump coastdown, natural circulation, reactor head heat transfer, and...

  • Age-related response of isolated rat hepatocytes to menadione and (R)-[alpha]-lipoic acid

    Creator:
    Graves, Jason T.
    Abstract:
    Age-related decline in the capacity of endogenous antioxidant systems complicates pharmaceutical use by the elderly by potentially increasing the toxicity of some compounds. Of particular interest is chemical detoxification via glutathione (GSH) and attendant GSH-requiring detoxification enzymes, e.g. GSH peroxidases (GPX) and GSH S-transferase (GST). These enzymes have been shown...

  • Feasibility of Thermal Restoration by Groundwater Additions in the Middle Fork John Day

    Creator:
    Hale, Abigail E.
    Abstract:
    Survival of ecological systems pivot on critical moments. In the arid John Day Basin of Eastern Oregon, extensive restoration of the stream and floodplain focused on supporting salmon has been ongoing for the past 20 years, but recurring short periods of extreme temperature increase and low flows result in mortality...

  • John Archibald Wheeler : a study of mentoring in modern physics

    Creator:
    Christensen, Terry M.
    Abstract:
    This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

  • Description and prediction of broad-scale spatial variability in expression of anadromy in female Oncorhynchus mykiss in the John Day River, Oregon, USA

    Creator:
    Mills, Justin S.
    Abstract:
    Partial migration is a common migratory behavior where some individuals in a population migrate and others do not. Patterns of partial migration can vary dramatically, especially for species that inhabit a wide range of environments. I described and predicted spatial variation in marine migration (anadromy) of female Oncorhynchus mykiss (steelhead...

  • Theoretical physics takes root in America : John Archibald Wheeler as student and mentor

    Creator:
    Christensen, Terry M.
    Abstract:
    John Archibald Wheeler (09 July 1911- ) is a familiar name to physicists and historians of physics alike. Among his many contributions to the corpus of knowledge, in 1939 John Wheeler and Niels Bohr co-authored the first paper on the generalized mechanism of nuclear fission. Beyond that seminal work, Wheeler...

  • The effects of differing hazelnut concentrations in hog finishing rations with respect to pork shelf-life and fatty acid composition

    Creator:
    Parker, Nathan B.
    Abstract:
    Commercial hog diets in the United States commonly contain lipid sources high in polyunsaturated fatty acids, most notably linoleic acid (18:2). This may result in greater deposits of linoleic acid in pork adipose tissue, contributing to an increased potential for lipid oxidation, high n-6/n-3 fatty acid ratio and increased fat...
