  • Mathematical and Computational Considerations of a Model of Microbiologically Induced Calcite Precipitation

    Creator:
    Barry, Zachary T.
    Abstract:
    In this paper, we discuss two possible modifications to a numerical solution method for a model of microbiologically induced calcite precipitation (MICP). MICP provides a means to seal cracks in the surfaces of geological structures. From a mathematical and computational point of view MICP has very interesting features which make...

  • Single-Cell Genomics of Uncultivated Marine Bacteria

    Creator:
    Landry, Zachary
    Abstract:
    Historically, the difficulty of obtaining pure cultures of abundant marine microbial plankton has an obstacle to reconstructing the underlying mechanisms of biogeochemistry in the ocean. While a number of dominant marine species from the ocean surface have been cultured, the dominant microbial plankton of the dark ocean proved far more...

  • Benefits and Trends of Sustainable Building Initiatives in Parks and Protected Areas

    Creator:
    Shelow, Zachary
    Abstract:
    Ensuring sustainable development is a growing societal concern, providing rationale to examine the current role and efforts towards implementing sustainable building initiatives within the United States. Sustainable building initiatives refer to the design, operation, and maintenance of a building while considering its conservation efforts and pollution reduction performance. These initiatives...

  • Terahertz Imaging and Nonlinear Spectroscopy of Semiconductors using Plasmonic Devices

    Creator:
    Thompson, Zachary James
    Abstract:
    In this dissertation, a series of studies in the field of terahertz (THz) science are presented, specifically using nonlinear THz spectroscopy. We exploit huge field enhancement and subwavelength confinement in plasmonic structures. There are three distinct projects which will be discussed: nonlinear THz spectroscopy using plasmonic induced transparency (PIT), THz-triggered...

  • Riparian vegetation composition and structure associated with channel morphology of headwater meadow streams in the Blue Mountains, northeast Oregon

    Creator:
    Toledo, Zachary O.
    Abstract:
    Relationships between the structure and composition of riparian vegetation with channel morphology were examined in three montane meadow streams in the headwaters of the Upper Grande Ronde River and North Fork John Day River in the Blue Mountains, northeast Oregon. Vegetation composition, root biomass, and channel morphology cross-sections were sampled...

  • Accelerating Power-to-Gas Energy Storage Through PEM Electrolyzer Development and Technoeconomic Forecasting

    Creator:
    Taie, Zachary
    Abstract:
    There is strong interest in the energy community to develop technologies that can diffuse low-cost, renewably generated electricity into difficult and slow to decarbonize sectors. One of the emerging areas of interest is renewable natural gas (RNG). RNG has low or no associated net greenhouse gas emissions and can be...

  • The effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin on T cell activation

    Creator:
    Shepherd, David M.
    Abstract:
    The immune system has been identified as a very sensitive target for the toxic effects of 2,3,7,S-tetrachlorodibenzo-p-dioxin (TCDD). Exposure to TCDD has been shown to disrupt the generation of both cell-mediated and humoral T cell-dependent immunity in laboratory animals; however, the mechanism remains unknown. In this dissertation, the hypothesis is...

  • An Analysis of Driver's Visual Attention When Exposed to Roadside Drone Operations

    Creator:
    Sova, Alden
    Abstract:
    Drones are being used increasingly in the transportation sector for roadside applications such as surveying, structural inspection, and traffic monitoring, which raises distraction concerns for drivers. This study examines the visual attention of a group of Oregon drivers to determine drones’ potential as distracting roadside elements. Eye tracking data was...

  • 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...

    Reed, Zachary H.
    Abstract:
    Increased sales of surimi seafood, with the majority as crabstick in the United States indicates that surimi based products are becoming more popular. With growing popularity, there is increased competition for market share. Under these circumstances, some companies may be willing to sacrifice product quality in order to facilitate manufacture...
