  • Downstream Rearing Chinook Salmon (Oncorhynchus tshawytscha) in the Upper Mainstem of the John Day River

    Creator:
    Scheu, Michael P.
    Abstract:
    Juvenile Chinook Salmon (Oncorhynchus tshawytscha) leave the natal reach at different times and move downstream at different rates which can increase their productivity by allowing them to utilize habitats on different temporal scales and spreading risk of localized stochastic events. This life history diversity can also allow fish to adapt...

  • The influence of aryl hydrocarbon receptor activation on T cell fate

    Creator:
    Funatake, Castle J.
    Abstract:
    2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds are well-recognized for their immunosuppressive activity, which is mediated through an intracellular receptor and transcription factor, aryl hydrocarbon receptor (AhR). Laboratory animals exposed to TCDD are less resistant to infection and have severely impaired humoral and cell-mediated immune responses. This dissertation addressed the hypothesis that...

  • Uncovering the mechanism of IL-4-mediated T cell survival

    Creator:
    Moscibrocki, Cathleen M.
    Abstract:
    Although IL-4 is a well-characterized multi-functional cytokine, its role as a survival factor in T cells is not completely understood. In an attempt to uncover IL-4-mediated survival, we studied caspase activation in primary mouse T lymphocytes undergoing death by neglect, activation-induced or steroid-induced cell death. Here, we identify the executioner...

  • Sound and death in John Haines's poetry

    Creator:
    Noble, Darren L.
    Abstract:
    Poet John Haines is best known for his first book of poetry, Winter News, which was published in 1966. The book contains poems about the Alaskan landscape that surrounded Haines during his many years of living in Richardson, Alaska. The recurring motifs in his poems include hunting, trapping, the Arctic...

  • Thinning effects on stand and tree growth : different perspectives on same old questions

    Creator:
    Romero Castaño, Pablo
    Abstract:
    The search for the stand density that optimizes growth and hence generates the maximum amount of wood is one of the philosopher’s stone in modern forestry. Since scientific methods were applied to forestry, numerous generations of foresters have studied the relations between stocking density and growth, obtaining diverse results and...

  • Investigations of regulatory T cell induction by 2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin during a graft-versus-host response

    Creator:
    Marshall, Nikki B.
    Abstract:
    The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...

  • 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...

  • Examination of Multiple Air Pollutant Exposure, the Food Environment, and Low Birth Weight in Los Angeles, County

    Creator:
    Coker, Eric S.
    Abstract:
    Exposure to urban outdoor air pollution is ubiquitous and low birth weight represents an important health disparity in the United States. While previous research suggests that exposure to outdoor air pollutants are associated with term low birth weight, few studies have evaluated the effects of multipollutant outdoor air exposures or...

  • Red tree voles in fragmented forests

    Creator:
    Piasecki, Jason T.
    Abstract:
    The red tree vole (Arborimus longicaudus) is an arboreal Arvicoline rodent endemic to conifer dominated forests of western Oregon and northwestern California. While commonly associated with old forests, often inhabiting stands over 80 years old, tree voles have also been found in young forests between 20 and 80 years old....

  • The Applicability of Linear Elastic Fracture Mechanics to Compressive Damage of the Carbon Fiber Reinforced Plastic Matrix

    Creator:
    Carpenter, Kevin T.
    Abstract:
    With the widespread replacement of aluminum with composite materials, particularly in aircraft structures, the lack of comprehensive understanding of these materials is unsettling. The complex nature of these materials, with respect to isotropic aluminum, makes the prediction of their mechanical response equally complex. The failure of carbon fiber reinforced plastic...
