  • Is Advection Important? An Examination of the Advective Dynamics of Sensible Heat and Their Influence onSubcanopy Carbon Fluxes in Heterogeneous Terrain

    Creator:
    Carrigg, Sean Stephen
    Abstract:
    Abstract Understanding small-scale bio-atmospheric interactions is becoming increasingly important as the global climate continues to change at breakneck speed. A theoretical model of the sensible heat budget of a forest is developed combining conservation equations and concepts from fluid dynamics. Budget components are computationally evaluated using micrometeorological data taken during...

  • Soil respiration flux in response to soil temperature, moisture, and pH

    Creator:
    Murphy, Bailey
    Abstract:
    Soil respiration has been identified as one of the largest natural sources of CO₂ to the global carbon cycle. Small alterations in the magnitude of soil respiration can have potentially large effects on concentrations of atmospheric CO₂ , making the rate at which respiration occurs of great scientific interest (Martin...

  • 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...

  • The Fixation of Atmospheric Nitrogen

    Creator:
    Fairchild, Jackson Kenelem
    Abstract:
    Much has been accomplished in the last few years toward the conservation of natural resources, and in this work the engineer has taken a leading part. The prevention of unnecessary waste, the utilization of hitherto useless by-products, and the economic production of the world's necessities are important features of this...
