  • Distribution and origin of organic matter preserved in modern surface sediments throughout Coastal SE Alaska

    Creator:
    Walinsky, Sarah E.
    Abstract:
    Twenty seven modern (top 1-2cm) sediment samples from multicores retrieved from throughout coastal SE Alaska were analyzed for their organic matter content and the source composition. Total organic carbon (TOC) as well as biogenic silica (bioSi), and calcium carbonate (CaCO3) content were analyzed to evaluate the organic matter content and...

  • Hydrological consequences of two native shrubs in semi-arid Senegal : patterns, processes, concepts and methods

    Creator:
    Kizito, Fred
    Abstract:
    Water availability is a critical limiting element in semi-arid ecosystem productivity and presents particular challenges in Sahelian countries such as Senegal. The landscapes are characterized by the presence of two common semi-arid shrubs (Piliostigma reticulatum and Guiera senegalensis), both of which may be important hydraulic regulators in these water-limited ecosystems....

    Groh, Fred
    Abstract:
    The Marcellus Shale Natural Gas play in Pennsylvania, since its inception, continues to be a source of contention for multiple Pennsylvania stakeholders. The issues that relate to natural gas extraction have seemingly impacted every community within the Marcellus Shale region in some form. As in most common pool resource...

  • Developmental ramifications of dithiocarbamate pesticide exposure in zebrafish

    Creator:
    Tilton, Fred Anthony, 1973-
    Abstract:
    Dithiocarbamates are widely used agricultural pesticides, industrial chemicals and effluent additives. DTCs and their related compounds have historical and current relevance in clinical and experimental medicine. DTC developmental toxicity is well established, but poorly understood. Dithiocarbamates according to the U.S. EPA have a mechanism of action involving, "the inhibition of...

  • An economic analysis of changes in exclusive farm use regulations for homesteads in Oregon : a case study in Yamhill County

    Creator:
    Chen, Li, 1976-
    Abstract:
    Criticisms to the new regulations created in 1994 governing dwellings in Exclusive Farmland Use zones (zones where agricultural activities are allowed outright) have triggered an overall scrutiny directed by the 70th Oregon Legislative Assembly. The objective of this study was to examine the influence of the new regulations on the...

  • A role for ceramide accumulation in age-related cardiac mitochondrial dysfunction

    Creator:
    Monette, Jeffrey S.
    Abstract:
    Ceramides are a group of lipids in the sphingolipid family that are potent cell signaling molecules. Elevations in ceramide levels above the norm generally lead to apoptosis. Evidence from in vitro studies suggests that accumulation of ceramides within mitochondria leads to dysfunction of the mitochondria. This includes inhibition of the...

  • Human bitterness detection thresholds of hop acids in beer and honey

    Creator:
    Kolpin, Kathryn M.
    Abstract:
    Alpha acids are found in the lupulin glands of hops cones. These acids have no bitterness of their own, but can be isomerized and subsequently hydrogenated to form bitter iso-α-acids and tetrahydroiso-α-acids respectively. Current literature values for the detection thresholds of iso-α-acid and tetrahydroiso-α-acid in lager beer have been reported...

  • An experimental approach to analyze large notched composite panels loaded in out-of-plane shear

    Creator:
    Froemming, Tyler M.
    Abstract:
    Identifying material characteristics of composites is important in designing any structural system. The aerospace industry relies on these material properties not only to design a functional aircraft, but also a safe and reliable one. Since carbon fiber composites are relatively new materials, little is known about its characteristics under certain...

    Creator:
    Scouse, Adam A.
    Abstract:
    Western juniper and cinnamon essential oils were combined with ethanol at 2.5, 5, and 10% concentrations by weight and applied to hybrid poplar (Populus trichocarpa x P. deltoids) veneers by vacuum soaking to produce a naturally durable wood veneer with increased mechanical properties for use in structural composites. Half of...

  • Ecology of populations of Van Dyke's salamanders in the Cascade Range of Washington State

    Creator:
    McIntyre, Aimee P.
    Abstract:
    The Van Dyke's salamander (Plethodon vandyke,) is a rare species endemic to Washington State. It has been found in cool moist microhabitats along streams, splash zones of waterfalls, and headwater seeps. We explored the association of the Van Dyke's salamander with hydrologic condition, geomorphology, disturbance characteristics, and vegetation structure in...
