  • 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...

    Creator:
    Cummings, Laura L.
    Abstract:
    The heroine of this fantasy novel is Alina who lives in a medieval-like time and place. The day before her 20th birthday, in an impetuous moment, she breaks a local superstition by standing in a sunbeam. This allows a fairy to kidnap her and take her to the fairy castle...

  • Investigating the ecological role of cell signaling in free-living marine heterotrophic protists

    Creator:
    Hartz, Aaron J.
    Abstract:
    Phagotrophic protists are major consumers of microbial biomass in aquatic ecosystems. However, biochemical mechanisms underlying prey recognition and phagocytosis by protists are not well understood. We investigated the potential roles of cell signaling mechanisms in chemosensory response to prey, and in capture of prey cells, by a marine ciliate (Uronema...

  • Evaluating Preventative Vision Care in Oregon Children

    Creator:
    Liau, Belinda
    Abstract:
    The Oregon Department of Education requires children to receive vision screening before entering elementary school, but does not require follow-up with an eye care professional after a failed screening. Whether such preventative vision care is effective at detecting children with vision problems was investigated through research from the American Optometric...

  • The Influence of grazing on active γ-Proteobacteria cells

    Creator:
    Wilson, Michelle Juliette
    Abstract:
    By identifying the relationships between abundance and metabolic activity in a bacterial community, we advance our knowledge of the marine carbon cycle. In the present study, our goal was to examine the role of protist grazing on the metabolic activity of γ- Proteobacteria in the upwelling system off the Oregon...

  • Gender Disparity in American Literary Fiction: Women Writing the Female Experience of Romantic Relationships in Short Fiction and a Collection of Original Short Stories

    Creator:
    Dealy, Rebecca Corinne
    Abstract:
    Unpublished female authors of American short fiction face many prejudices in fiction publishing, submission, and reviewing. These prejudices stem from the writer’s position in a gender-unequal society. Feminist fiction provides dimensional, diverse female characters in relationships where previous fiction had offered only stereotypes whose role was to support and reflect...

  • 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...

  • Bacterioplankton in the Oregon upwelling system: distribution, cell-specific leucine incorporation, and diversity

    Creator:
    Longnecker, Krista
    Abstract:
    Marine bacterioplankton play an important role in global elemental cycles because they return carbon dioxide and nutrients to the biosphere as they reduce organic matter. Furthermore, marine bacterioplankton are not uniformly active, and subpopulations of the in situ community may be more or less active at any given time. Defining...

    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...

  • Local Existence for a Non-local Multi-Species Advection-Diffusion Equation with Newtonian Potential

    Creator:
    Radke, Zachary
    Abstract:
    In biological models, advection is inherently a non-local process. Coupled with diffusion, it typically models chemotaxis, which is the response of bacteria to the presence of some chemo attractant. For example, E. coli cells use their flagella to probe their surroundings to determine where they should move. The advection-diffusion equation...

    Abstract:
    Extensions of the fractional Brownian fields are constructed over a complete Riemannian manifold. This construction is carried out for the full range of the Hurst parameter α ∈ (0, 1). In particular, we establish existence, distributional scaling (self-similiarity), stationarity of the increments, and almost sure H¨older continuity of sample paths....

    Abstract:
    Null networks are a type of random graph that is favored for the analysis of a wide variety of real-world networks, including gene-regulatory networks, food webs, and species co-occurrence matrices. As a hypothesis-generating tool, null networks are invaluable because they can reveal network motifs and unusual large-scale properties of networks...

    Abstract:
    Coastal stream basins are of great importance to efforts aimed at refining our understanding of the earliest populations that inhabited the ancient Oregon coast. However, geomorphic responses to post-glacial sea level rise in these settings has produced depositional environments that destroy or deeply bury late Pleistocene and early Holocene-age archaeological...
