  • The Design and Construction of a 5 K.W., D. C. generator

    Creator:
    Gilkey, Jesse Smart and Chapman, Alexander Kesterson
    Abstract:
    Since this treatise is to deal only with the construction of one special machine it is unnecessary to go into an extended discussion of dynamo electric machinery in general. Some of the parts common to all electric machinery of this character will be mentioned and then a short account of...

  • Impacts of agricultural drainwater and contaminants on wetlands at Kesterson Reservoir, California

    Creator:
    Schuler, Carol Ann, 1946-
    Abstract:
    Kesterson Reservoir (Kesterson) received subsurface agricultural drainwater containing high levels of salts and other minerals from farmland in the San Joaquin Valley of California. Aquatic plants and invertebrates were sampled at Kesterson in May, August, and December of 1984. The reservoir supported a different biota and lower species diversity than...

  • 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...

  • 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...

  • 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...

  • A study of the effect of the rotor coil couplings of a synchronous machine on its predicted transient response

    Creator:
    Nehrir, Mohammad Hashem
    Abstract:
    The effect of the mutual inductances between the rotor coils of a synchronous machine on its defined reactances and predicted transients are investigated. Two linearized models of the machine are considered. One uses the Laplace-Transform approach, with minimum number of assumptions on the inter-coil couplings, in developing a model for...

  • Willamette Mission archeological project : phase III assessment

    Creator:
    Chapman, Judith Sanders
    Abstract:
    The Willamette Mission archeological project consists of a broad program of cultural research in the fields of archeology, history, and architecture. The study focuses on the first Methodist mission in the Pacific Northwest. Archeological excavations were conducted in 1980 to locate the site of the mission, to assess the site's...

  • Endogenous and antiviral RNA silencing pathways in Arabidopsis

    Creator:
    Chapman, Elisabeth J.
    Abstract:
    RNA silencing pathways are required for a wide variety of processes in most eucaryotes. In plants, small-interfering RNA (siRNA) arising from transposons and other repetitive sequences is associated with heterochromatin formation and maintenance. MicroRNAs and trans-acting siRNAs encoded at discrete loci function as negative regulators of gene expression by triggering...

  • Cytokinin production by Agrobacterium tumefaciens

    Creator:
    Kaiss-Chapman, Richard Wilkinson
    Abstract:
    Certain plant-associated prokaryotes such as Corynebacteriurn fascians and Agrobacterium tumefaciens are known to produce substantial levels of cytokinins. In view of the fragmentary and presumptive evidence available on the quantitative and qualitative levels of cytokinins produced by A. tumefaciens, it was decided to conduct a study of the cytokinins produced...
