  • Tidal influence on downstream fining in gravel-bed rivers

    Creator:
    Coles, Derron Rafiq
    Abstract:
    This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

  • A methodology for efficient substrate noise estimation from large scale digital circuits in mixed signal SoC's

    Creator:
    Held, Martin A.
    Abstract:
    A methodology for rapid estimation of substrate noise generated by digital circuitry in mixed-signal circuits is presented. This methodology is incorporated into the Silencer! framework, and also provides for future improvements including pre-layout noise estimation. Measurements of a test chip fabricated in the TSMC o.25[mu]m heavily doped logic process validate...

  • Effects of plant community characteristics on insect abundance : implications for sage-grouse brood-rearing habitat

    Creator:
    Ersch, Erica A.
    Abstract:
    A causative factor in declining greater sage-grouse (Centrocercus urophasianus) populations is reduced annual recruitment due to poor habitat quality. Sage-grouse population decline is concurrent with a decline in the extent and quality of the sagebrush (Artemisia sp.) biome. However, current research has shown a positive relationship between sage-grouse brood and...

  • Characterization of reinforced fill soil, soil-reinforcement interaction, and internal stability of very tall MSE walls

    Creator:
    Walters, James J.
    Abstract:
    In many geotechnical design situations involving tight right-of-way constraints, Mechanically Stabilized Earth (MSE) walls are often the most cost-effective and reliable earth retention technology among available alternatives. However, few well-documented case histories with detailed material testing, instrumentation programs and construction observation of performance are available in the literature. Despite the...

  • Carbon cycle variability during the last millennium and last deglaciation

    Creator:
    Bauska, Thomas K.
    Abstract:
    The exchange of carbon on earth is one of the fundamental processes that sustains life and regulates climate. Since the onset of the Industrial Revolution, the burning of fossil fuels and anthropogenic land conversion have altered the carbon cycle, increasing carbon dioxide in the atmosphere to levels that are unprecedented...

  • Development of mucosal vaccines for avian influenza A virus composed of recombinant Lactococcus lactis and Streptococcus gordonii

    Creator:
    Reese, Kaleb A.
    Abstract:
    Novel mucosal vaccines (LL-M2e, LL-HAe, SG-HAe) were constructed from live, non-pathogenic Lactococcus lactis or Streptococcus gordonii that express conserved regions of HA or M2 antigens from avian influenza virus (AIV) A. All three vaccines evoked antigen-specific serum immunoglobulin G (IgG) responses in vaccinated chickens. The addition of the adjuvant cholera...

  • Biosynthesis studies and mutasynthesis of myxobacterial secondary metabolites

    Creator:
    Knight, Eva W.
    Abstract:
    Myxobacteria represent an interesting class of Gram-negative soil bacteria. These bacteria utilize organic materials from the environment as a food source by the action of their extracellular hydrolytic enzymes. They grow vegetatively in the presence of adequate nutrients. During starvation conditions, however, they aggregate and form multicellular structures called fruiting...

  • Effects of Biochar-Based Seed Coatings on Seed Germination and Seedling Vigor of California Brome (Bromus carinatus L.) and Blue Wildrye (Elymus glaucus L.)

    Creator:
    James, Matthew Scott
    Abstract:
    California brome and blue wildrye are important native grass species in the Pacific Northwest. However, both species have been reported to have low emergence under less than favorable field conditions. Seed coating is used to improve emergence and stand establishment of various crops. Three studies were carried out to determine...

  • Approaches to The Optimization of Honey-Based Fermentations

    Creator:
    Kartik, Kritika
    Abstract:
    The fermentation of honey-based musts has been a feature of civilization for millennia. Typically comprised of 75-90% (w/w) simple (i.e. fermentable) sugars, the glucose and fructose present are readily fermented by either pitched or adventitious micro-organisms. Nevertheless, despite its venerable heritage, honey-based fermentations are prone to inconsistency, and it is...

  • Feasibility Study on MHD Energy Conversion for Applications in Liquid Metal Cooled Nuclear Reactors

    Creator:
    Qiu, Hanrui
    Abstract:
    The application of two-phase magnetohydrodynamic(MHD) in liquid metal cooled nuclear reactors presents opportunities to simplify the power generation system by eliminating moving components like a turbine for enhanced safety. The proposed system in this thesis consists of two loops with immiscible working fluids. The compressed gas expands in the two-phase...
