  • Tropical origins of North and South Pacific decadal variability

    Creator:
    Shakun, Jeremy D. and Shaman, Jeffrey
    Abstract:
    The origin of the Pacific Decadal Oscillation (PDO), the leading mode of sea surface temperature variability for the North Pacific, is a matter of considerable debate. One paradigm views the PDO as an independent mode centered in the North Pacific, while another regards it as a largely reddened response to...

  • Community composition and activities of denitrifying bacteria in soils

    Creator:
    Rich, Jeremy J.
    Abstract:
    Few studies have directly compared denitrifying community composition and activities in soils by coupling molecular-genetic techniques and traditional measures of denitnfication. I investigated communities of denitrifying bacteria from adjacent meadow and forest soils in the Cascade Mountains, Oregon. A key gene in the denitrification pathway, N₂O reductase (nosZ), served as...

  • Hydrogeologic field investigation and groundwater flow model of the southern Willamette Valley, Oregon

    Creator:
    Craner, Jeremy D.
    Abstract:
    Elevated groundwater nitrate (NO3 -) concentrations in the Southern Willamette Valley (SWV) caused the Oregon Department of Environmental Quality (ODEQ) to declare a Groundwater Management Area (GWMA) in Spring, 2004. To better understand direction of groundwater flow, groundwater age, and nitrate transport pathways of the SWV we developed a steady-state...

  • Winterfat seed viability and dormant season livestock grazing

    Creator:
    Leary, Ryan
    Abstract:
    Krascheninnikovia lanata (winterfat) is a valuable forage species with an average of 10% crude protein during winter when there are few nutritious options for livestock and wildlife. However, excessive grazing throughout the west has negatively impacted survival of winterfat stands. We hypothesized that four years rest from dormant season livestock...

  • Generation of narrowband THz pulses and THz studies of ultrafast phenomena in semiconductor quantum wells

    Creator:
    Danielson, Jeremy R.
    Abstract:
    This work comprises two main parts: creating and shaping narrowband, pulsed THz radiation in a table-top optical setup; and applying THz pulses to semiconductor nanostructures to study electron dynamics. I developed a scheme to shape the THz output of a fanned-out periodically poled lithium niobate (PPLN) crystal. The pulses are...

  • Defining intensity of skeletal loading in children

    Creator:
    Bauer, Jeremy J.
    Abstract:
    While exercise can be prescribed for improving cardiovascular and muscle health, no prescription exists for increasing bone mass. Because bone deformation rate has been identified as an important variable related to osteogenesis, estimates of skeletal loading during human activities likely characterize the associated osteogenic stimulus. However, estimates of body segment...

  • Luminescent sulfides and solution-deposited oxide thin films

    Creator:
    Anderson, Jeremy T.
    Abstract:
    Solid state luminescent sulfides are prepared as powders in order to elucidate the relationship between structure and light emission. While the sulfides studied in this dissertation are known phosphors, materials are investigated in a variety of new ways. Elementary properties and structures of MgS are reviewed, and preparation of MgS...

  • Discriminating between landslide sites and potentially unstable terrain using topographic indices

    Creator:
    Appt, Jeremy
    Abstract:
    A landslide inventory, statistical analyses and a Geographic Information System (GIS) are used to analyze landslide sites and potentially unstable terrain in the Oregon Coast Range. The objectives are to evaluate the efficacy of locating landslide sites with topographic variables and discriminate the difference between sites where landslides have and...

  • Assessment of pre-fire season physical fitness training among Bureau of Land Management wildland firefighters

    Creator:
    Hawkins, Jeremy R.
    Abstract:
    Wildland firefighters encounter many situations during forest fires that require them to rely on their knowledge, experience, and fitness level for survival While energy expenditure of wildland firefighters on the fire line has been well established, relatively little is known about the physical fitness level of wildland firefighters when they...

  • Kinetics and kinematics of prepubertal children participating in osteogenic physical activity

    Creator:
    Bauer, Jeremy
    Abstract:
    Introduction: Recent reports in exercise related bone research have shown increased bone mineral content (BMC) at the femoral neck for prepubescent children participating in exercise programs consisting of repeated drop landings from a height of 61 cm. Increases in BMC from this type of exercise are believed to be the...
