  • Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

    Creator:
    Bowen, Michael S.
    Abstract:
    Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

  • Developing New Routes for Mechanical Characterization of Metal-Organic Frameworks

    Creator:
    Maack, Bryan A.
    Abstract:
    Metal-organic frameworks (MOFs) represent an exciting, new class of porous materials. Their hybrid organic-inorganic structure opens up near infinite possibilities to tune and design their structure for specific properties and applications. A new generation of flexible MOFs, following a generation of stiff MOFs, has created additional design space and complexity....

  • Top-down Influences of bald eagles on common murre populations in Oregon

    Creator:
    Horton, Cheryl A.
    Abstract:
    Populations of organisms are influenced by both top-down (predator driven) and bottom-up (environment or resource driven) effects. Seabird research has largely focused on bottom-up factors influencing reproduction, with little emphasis on top-down. Our goal was to better understand top-down impacts on colonial nesting seabirds over a range of spatio-temporal scales....

  • Phylogeography and population structure of least terns (Sterna antillarum)

    Creator:
    Draheim, Hope M.
    Abstract:
    Historically, least terns (Sterna antillarum) were one of the most common tern species in North America. However, population declines have resulted from direct and indirect anthropogenic pressures on their breeding and foraging habitat. Three subspecies of least terns have been described within the United States: California least tern (S. a....

  • Lifestyle reduction of the risk of premature sexual activity in a high school population of American Seventh-Day Adventists : Valuegenesis 1989

    Creator:
    Weinbender, Miriam L. M.
    Abstract:
    BACKGROUND: Goals for reduction of adolescent American health risks include reduction of prevalence of early initiation of sexual activity among teens in the United States to <15% for fifteen year olds and <40% for seventeen year olds. Such a prevalence reduction would concomitantly reduce the risks for both unwanted teen...

  • Observational study of buffered bike lane design implementation of roadway bicycling in Portland, Oregon

    Creator:
    Rios, Elizabeth A.
    Abstract:
    Bicyclists are one of the highest and most vulnerable road users. This is due to the higher likelihood of being seriously injured when involved in a crash. This research seeks to understand two different behavioral interactions of an implemented facility user: the motorist (secondary user) and bicyclist (primary user). The...

  • Design and testing of intrusive conductivity probes for the measurement of two-phase flow parameters

    Creator:
    McCreary, David M.
    Abstract:
    This thesis examines two techniques for measuring two-phase flow parameters in an air/water system using intrusive conductivity probes. Specifically, the theoretical derivation for measuring void fraction and interfacial area using a two-sensor needle-type probe is derived, and a statistical analysis of the accuracy using the two-sensor probe for measuring interfacial...

  • Natal source contributions of Pacific cod (Gadus macrocephalus) recruits in the southeastern Bering Sea

    Creator:
    DiMaria, Ruth A.
    Abstract:
    Effective and sustainable fisheries management not only depends on identifying and defining stocks (fundamental unit of management), but also on having knowledge of factors influencing the abundance, distribution and connectivity of stocks. Population structure of Pacific cod (Gadus macrocephalus) in the southeastern Bering Sea (EBS) remains unresolved although genetic data...

  • Diversity and abundance of birds across a hardwood gradient in early seral Douglas-fir plantations

    Creator:
    Ellis, Tana M.
    Abstract:
    Recent evidence suggests that population declines of some avian species may be driven primarily by reduced quantity and diversity of early-successional habitat on the breeding grounds. Increasing intensity of forest management on private lands and decreased harvest rates on federal lands has resulted in a loss of the diverse early-successional...

  • A comparison of early marine residence in hatchery and natural Chinook salmon (Oncorhynchus tshawytscha)

    Creator:
    Claiborne, Andrew M.
    Abstract:
    The mechanisms of mortality during critical life stages of fish are not well-understood and, for many species, it is not clear if the mechanisms are similar for naturally and artificially propagated individuals. For Chinook salmon (Oncorhynchus tshawytscha), natural fish potentially face negative interactions, such as competition, and survival disadvantages, such...
