  • Isotopic and Geochemical Signatures of Mantle and Crustal Contributions in Rhyolites from Okataina and Taupo volcanoes, New Zealand

    Creator:
    Rocco, Nicole D.
    Abstract:
    Silicic caldera-forming eruptions are some of the largest and most destructive volcanic eruptions known, and present significant local and global hazards. The underlying processes within crustal magma plumbing systems that lead to the accumulation and eruption of large volumes of evolved magma remain enigmatic, yet there is broad consensus that...

  • Developing a basis for characterizing precision of estimates produced from non-probability samples on continuous domains

    Creator:
    Cooper, Cynthia
    Abstract:
    This research addresses sample process variance estimation on continuous domains and for non-probability samples in particular. The motivation for the research is a scenario in which a program has collected non-probability samples for which there is interest in characterizing how much an extrapolation to the domain would vary given similarly...

  • Antibiotic Resistance Gene Transfer in Oysters as a Result of Fecal Pollution

    Creator:
    Cooper, Rebecca
    Abstract:
    Antibiotic resistance is an increasing problem in many species of bacteria today, with pathogens an important focus. Fecal contamination of shellfish is already a concern due to potential pathogens. This report examines the possibility of resistance gene transfer between microbes, due to fecal bacteria, within the oyster. In this study,...

  • Form Systems for Database User Interface: 4th Pimension vs. Oracle (Macintosh Version)

    Creator:
    Cooper, Karen
    Abstract:
    Forms are the most common means of interacting with databases. Database develop1;11ent products offer differing capabilities for creating forms. We will compare the form design features available using 4th Dimension and Oracle database products. These two products have the most complete set of features compared to other micro computer database...

  • Building and sharing spatial metaphors for the Catalogue of Oregon Marine and Coastal Information

    Creator:
    Cooper, Colin A.
    Abstract:
    Spatialization is an innovative way to expand searching capabilities for a marine/coastal reference database by using a metaphorical map framework to establish a sense of place for non-spatial information. Spatializing the Catalogue of Oregon Marine and Coastal Information (COMC1), a coastal reference database, enables the marine and coastal resource community...

  • Modeling Elevation-Dependent Snow Sensitivity to Climate Warming in the Data Sparse Eastern Oregon Cascades

    Creator:
    Cooper, Matthew Guy
    Abstract:
    In the mountains of the Western US, shifts in the timing and magnitude of snow water equivalent (SWE) over the past century are well documented and attributed to climate warming, but the magnitude of sensitivity depends on elevation. We modeled the spatial distribution of SWE and its sensitivity to climate...

  • Beaver ecology on the west Copper River Delta, Alaska

    Creator:
    Cooper, Erin E.
    Abstract:
    Since the 1964 earthquake and geologic uplift, beavers (Castor canadensis) have expanded their historic range from the inland (outwash plain) Copper River Delta, Alaska to the once tidally influenced areas of the outer area (uplifted marsh). The uplift presents a unique opportunity to observe beaver expansion, habitat selection and influence...

  • Effect of Solar System Models on Pulsar Timing Experiments

    Creator:
    Nicolaysen, Cooper
    Abstract:
    Gravitational wave (GW) astronomy is a key ingredient in confirming Einstein’s theory of General Relativity and showing how the universe sends ripples through spacetime, distorting distances between two points. The confirmation of high-frequency GWs observed by The Laser Interferometer Gravitational-Wave Observatory (LIGO) in 2015 was a breakthrough in our understanding...

  • Foliar respiration in an old-growth coniferous forest

    Creator:
    Cooper, Clifton E.
    Abstract:
    Foliar respiration forms a large component of the carbon balance of any coniferous forest. We examine seasonal, interannual, spatial and interspecific variation of foliar maintenance respiration in a forest in Washington, USA, with measurements made quarterly for >4 years on 400-year old trees of Pseudotsuga menziesii, Tsuga heterophylla and Thuja...

  • Investigating 2D semiconductor contacts for Cooper-pair light-emitting diode applications

    Creator:
    Nichols, Dublin M.
    Abstract:
    Future quantum technologies will require high-efficiency, on-demand sources of entangled photons. A possible route to building such light sources employs two-dimensional (2D) semiconductors interfaced with a source of Cooper pairs. To investigate the possibility of such devices, we are testing methods to make high transparency n-type contacts, p-type contacts, and...
