  • The Generation of a Zebrafish Microbial Culture Collection to Facilitate Mechanistic Understanding of Host-Microbe Interactions

    Creator:
    VanderHoek, Zoe K.
    Abstract:
    A rapidly expanding body of evidence suggests that relationships exist between the microbiome and vertebrate health and disease. The zebrafish is a frequently utilized model organism to support this claim. Specifically, its gut microbiome is an advantageous resource for the study of microbiome health and diversity. While it is an...

  • Commercial Motor Vehicle Safety Belt Usage in Oregon

    Creator:
    Cowgill, Brett Thomas
    Abstract:
    In ¬¬¬¬2009 the Federal Motor Vehicle Safety Administration (FMCSA) conducted the “Safety Belt Usage by Commercial Motor Vehicle Drivers Survey” for the National Highway Traffic Safety Administration (NHTSA). The survey found that, nationally, 74% of commercial truck drivers wear their safety belts at all times. In the western region of...

  • Limit Equilibrium-Based Assessment of the Internal Stability of Geosynthetic Reinforced Soil Structures Subject to Seismicity

    Creator:
    Loving, Carly K.
    Abstract:
    Design of Geosynthetic-Reinforced Soil Structures (GRSS) require sufficient rear pullout anchoring capacity in order to maintain internal stability. Length requirements are amplified when reinforcement coverage ratios or seismicity is considered, potentially resulting in uneconomical GRSS design lengths. This study describes the influence of reinforcement length, coverage ratio, and pseudostatic seismic...

  • Simulated and Experimental Characteristics of Analysis Techniques for ZrCuAlNi/AlOx/Al Metal-Insulator-Metal Tunnel Diodes

    Creator:
    Tan, Cheng
    Abstract:
    This project examines the results of current-voltage conduction mechanism analysis techniques simulated under assumed conduction conditions. Thermionic emission and Fowler-Nordheim tunneling conditions are simulated and analyzed. The resulting plots show how devices behave under different condition mechanisms. The effects of different conduction mechanisms on the results of various analysis techniques...

  • Modeling and Finite Element Analysis of a Standard Concrete Canoe

    Creator:
    Stache, Stephanie S.
    Abstract:
    This thesis project provides a guiding framework for the structural analysis portion of the National Concrete Canoe Competition (NCCC). Step-by-step instructions on how to 3-dimensionally model a “standard” sized concrete canoe in AutoCAD Civil 3D, import the model into SAP2000, and proceed to analyze the canoe with the SAP2000 finite...

  • Development of Fluorometric Assay for the Determination of β-glucosidase Activity in Brewing Yeasts

    Creator:
    Molitor, Andrew
    Abstract:
    Glycosides are natural molecules found in many plants and hold potential to release new flavors and aromas into alcoholic beverages, particularly beer and wine. One way to free these flavors and aromas is by enzymatic hydrolysis catalyzed by βglucosidase. The activities of β-glucosidase are strain and species dependent in yeast...

  • Mutagenic Analysis of Victorin Sensitivity in Arabidopsis thaliana and Avena sativa

    Creator:
    Seshadri, Rishi S.
    Abstract:
    The fungal pathogen Cochliobolus victoriae, the causal agent of Victoria blight, produces a host-selective pathogenicity factor called victorin. In Arabidopsis thaliana, a dominant gene called "supersense" (SSN) confers constitutive victorin sensitivity at very low concentrations. SSN encodes a nucleotide-binding leucine-rich-repeat (NB-LRR) protein. In the SSN-carrying Heiligkreuztal 2 ecotype (TAIR Germplasm...

  • Diastatic Activity in Citra® Hops as a Function of On-Bine Maturity

    Creator:
    Long, Aidan T.
    Abstract:
    Dry-hopping has grown from a novel to widespread technique in commercial craft beer production. It yields large returns in aroma that cannot be emulated with kettle hopping. However, it also leads to beer refermentation post-dry-hopping, a phenomenon colloquially referred to by U.S brewers as “hop creep.” This is a result...

  • Location of the neutral axis in wood beams

    Creator:
    Holm, Sarah C.
    Abstract:
    It is commonly accepted that for the analysis of wood beams, the neutral axis coincides with the centroid of the beam. Although this assumption is used in analysis, wood is not an isotropic material, as it has different elastic properties in the tangential, radial and longitudinal directions, nor is it...

  • Soil Property Effects on Willamette Daisy (Erigeron decumbens) within William L. Finley National Wildlife Refuge

    Creator:
    Day, Emily S.
    Abstract:
    Plant species diversity plays an important role in maintaining ecosystem function and the services that ecosystems provide. Diversity is threatened by habitat loss, invasive species, and global climate change. Willamette Daisy (Erigeron decumbens), an endangered species, has been reintroduced at two different sites (Field 29 and 8N) within William L....
