  • Synthesis of metabolites from the ascomycetes : I. The synthesis and absolute configuration of leptosphaerin : II. Approaches to the synthesis of byssochlamic acid

    Creator:
    Pallenberg, Alexander J.
    Abstract:
    Part I. The total synthesis of (+)-leptosphaerin (2), a metabolite of the marine Ascomycete Leptosphaeria Oraemaris (Linder) was achieved, unambiguously establishing both the relative and absolute stereochemistry of this natural product. This synthesis also resolved the long-standing question of which of the isomeric structures 1 or 2 correctly represents the...

  • The Alexander polynomial

    Creator:
    Scherich, Nancy
    Abstract:
    The Alexander polynomial is a well understood classical knot invariant with interesting symmetry properties and recent applications in knot Floer homology. There are many different ways to compute the Alexander polynomial, some involving algebraic techniques and others more geometric or combinatorial approaches. This is an interesting example of how different...

  • Interactions of wind-driven and tidally-driven circulation in the Oregon coastal ocean

    Creator:
    Osborne, John J.
    Abstract:
    Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations). The...

  • Investigating Alternative Irrigation Strategies and Sources for the Cool-Humid Willamette Valley

    Creator:
    Olsen, Conner J.
    Abstract:
    Rising human populations and climate change are putting increasing demands on our already-limited freshwater sources. In response to these concerns, homeowners and municipalities have been encouraged to replace turfgrass – a plant with relatively high irrigation needs – with drought-tolerant plants that do not require frequent irrigation. However, the many...

  • Effect of adult aquatic insect life history on return to Lookout Creek, H. J. Andrews Experimental Forest, Oregon

    Creator:
    Farrand, Alexander Mark
    Abstract:
    Aquatic insects that emerge out of streams to mate represent a potential energy flux to terrestrial food webs. The relative success of an individual aquatic adult insect is whether it survives long enough to produce offspring, i.e. mate and return to the stream to oviposit eggs. Some characteristics of the...

  • Hybrid computer simulation of wind-driven ocean currents

    Creator:
    Vithayathil, Francis Joseph
    Abstract:
    A simulation method using a hybrid computer is developed in this dissertation to enhance the study of wind-driven ocean circulation. The simulation is based on the mathematical model developed by Ekman. Pure digital simulation is not economical due to excessive computer time required for the solution of the partial differential...

  • From the Classroom to the Boardroom: Behaviors Associated with Both Student Leader and Business Leader Effectiveness

    Creator:
    Dodge, Miles
    Abstract:
    Each year thousands of college graduates enter the business world armed with skills accumulated as student leaders, but how applicable are these skills to the business world? While there are many studies on learnable behaviors associated with effective student leadership and many studies on behaviors associated with effective business leadership,...

  • Ensemble-variational data assimilation for dynamically challenging coastal ocean circulation

    Creator:
    Pasmans, Ivo
    Abstract:
    Currently, forecasts produced by the Oregon-Washington (OR-WA) Coastal Ocean Forecast System are constrained by assimilation of only surface observations. The 4-dimensional variational (4DVAR) data assimilation (DA) algorithm is utilized to combine the model and the data, with the time-independent forecast ("background'') error covariance B. In this study, two possible improvements...

  • Coastal ocean variability inferred from high resolution models : Two case studies

    Creator:
    Mauch, Matthew L.
    Abstract:
    In this thesis, high resolution ocean models are used to evaluate and forecast coastal ocean variability in two different applications. In the first study, the 2-km resolution ocean circulation model for the Eastern Bering Sea is utilized to understand whether slope-interior exchange along the path of the Aleutian North Slope...
