  • The Deathscape of St. Paul: Historic Cemeteries as Cultural Landscapes

    Creator:
    Boulware, Brooke L.
    Abstract:
    A cultural landscape analysis of two historic cemeteries in St. Paul, Oregon demonstrates that the residents of this early community were unknowingly using grave markers to express their worldview and the identities that they felt were most important. Because of the historical and cultural development of this community as the...

  • Modeling and development of fabrication method for embedding membrane based microvalve in bulk microfluidic device

    Creator:
    Abhinkar, Bindiya S.
    Abstract:
    PDMS membrane-based microvalves are becoming increasingly more important for the control of fluid flow within MECS applications such as microreactors used to synthesize nanoparticles and biological macromolecules. The motivation for pursuing PDMS membrane-based microvalves is for implementing a plug flow microreactor to simulate slug flow yielding a narrower residence time...

  • Submarine plateau volcanism and Cretaceous Ocean Anoxic Event 1a : geochemical evidence from Aptian sedimentary sections

    Creator:
    Walczak, Paul S.
    Abstract:
    Marine sediments exceptionally rich in organic carbon, known as black shales, occur globally but intermittently in well correlated Cretaceous successions. The presence of black shales indicates that sporadic, ocean-wide interruption of normal respiration of marine organic matter during oxygen-deficient conditions has occurred. Submarine volcanism on a massive scale, related to...

  • Disciplining the reception of Darwin : the botanical and sociological work of Lester Frank Ward

    Creator:
    Zimmerman, Katharine
    Abstract:
    The publication of Charles Darwin’s On the Origin of Species, truly a synthesized work of natural history, coincided with the emergence of specialized disciplines in the 19th century. This thesis aims to explore the relationship between the specialization of knowledge, in the form of disciplinization, and the reception of new...

  • Investigating arc behavior in a DC vacuum arc remelting furnace using magnetic flux density measurements

    Creator:
    Woodside, Rigel
    Abstract:
    The behavior of a metal vapor plasma arc in a vacuum arc remelting (VAR) furnace is believed to contribute to the formation of defects in reactive metal and super-alloy ingots. Industry standard instrumentation, which includes electric current and voltage measurements, can asses the stability of an arc but cannot predict...

  • Reducing sediment production from forest roads during wet-weather use

    Creator:
    Toman, Elizabeth Myers
    Abstract:
    Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...

  • Influence of cover crops on vine performance at two Willamette Valley vineyards

    Creator:
    Sweet, Rebecca Marie
    Abstract:
    It is estimated that 50-75% of Oregon vineyards cultivate at least every other alley in order to 1) reduce water stress 2) increase vineyard canopy temperatures and 3) increase nutrient availability. Because many vineyards are situated on steep hillsides, frequent tillage could result in increased soil erosion, decreased soil quality...

  • Vegetation response to prescribed fire in mountain big sagebrush ecosystems at Lava Beds National Monument, California

    Creator:
    Ellsworth, Lisa M.
    Abstract:
    Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused...

  • Persistence of western juniper resource islands following canopy removal

    Creator:
    Miwa, Christopher
    Abstract:
    Western juniper (Juniperus occidentalis) cover has more than doubled within the last century and currently occupies over 9 million acres in the Intermountain West. Encroachment has altered the spatial distribution of soil nutrients and plants in these systems, forming nutrient enriched 'resource islands,' under tree canopies. The purpose of this...

  • Spatial patterns of fuel management activities and their effects on wildfire behavior

    Creator:
    Kim, Young-Hwan
    Abstract:
    Fuel management has been used as an effective local strategy to reduce the undesirable consequences of wildfires. Many efforts toward scheduling of fuel management activities across a broader landscape have been proposed, with the hope of achieving larger landscape-scale management effects. However, scheduling of fuel management treatments across the broader...
