  • Molecular origins of peptide entrapment in polyethylene oxide layers

    Creator:
    Wu, Xiangming
    Abstract:
    A more quantitative understanding of peptide entrapment and elution from otherwise protein-repellent polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. Here we describe criteria for peptide integration and structural change within the PEO brush, and discuss the reversibility of peptide...

  • Opening Pandora's Box at the Roof of the World : The Past and Present of Avian Influenza Science

    Creator:
    Canavan, Barbara C.
    Abstract:
    By means of a case study and historical analysis, this dissertation examines the past and present of avian influenza. By integrating disconnected histories of human and animal influenza, this dissertation links historical insights with the concerns of contemporary avian flu science. It is not only a natural history of avian...

  • Exploring the structural dynamics of human understanding : an historico-philosophical analysis of the problem of meaning in Heidegger and Bohr

    Creator:
    Tattersall, Mason
    Abstract:
    This dissertation explores the structural dynamics of human understanding and particularly the concept of meaning and its connections to concepts of ultimate ground, necessity and contingency, language, and perception. It focuses on the history of the concept of meaning in early twentieth-century European physics and philosophy, through an analysis of...

  • Forms of Life: Goethe’s Impact on Twentieth-Century Anglophone Botany and Morphology

    Creator:
    Hahn, Andre M.
    Abstract:
    This dissertation examines the impact of the German naturalist and literary figure Johann Wolfgang von Goethe’s ideas on twentieth century Anglophone plant morphology and biology. Goethe interpreted the organ forms of flowering plants as metamorphoses of each other. His literary, historical, and philosophical writings suggest themes of alienation from and...

  • Topologically-Guided Robotic Information Gathering

    Creator:
    McCammon, Seth
    Abstract:
    Information gathering tasks, such as terrestrial search and rescue, aerial inspection, and marine monitoring, require robotic unmanned systems to make decisions on how to travel within an environment to maximize or minimize a path-dependent information objective function. The distribution of information throughout the environment is the result of various processes,...

    Abstract:
    Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location,...

    Abstract:
    The public controversy over possible health hazards from radioactive fallout from atomic bomb testing began in 1954, shortly after a thermonuclear test by the United States spread fallout world wide. In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...

    Creator:
    Kellar, Brenda M.
    Abstract:
    The use of honey bees to pollinate apple orchards seems natural, even inevitable. This dissertation examines the relationship of beekeeping and apple growing in Hood River, Oregon in the mid-nineteenth to the mid-twentieth centuries, as a case study in the development of commercial pollination service. Within this time period the...

    Abstract:
    While historiography and interest in Tudor England at both the popular and specialist levels presents few signs of diminishing, there may nonetheless exist a sense that we have little left to learn about this period and its culture.
