  • Provenance, lifespan, and phylogeny : testing a conceptual framework for plant community management

    Creator:
    Benfield, Cara D.
    Abstract:
    Successful conservation management requires an understanding of how species respond to intervention. Native and exotic species may respond differently to management interventions due to differences arising directly from their native or exotic origin (i.e., provenance) or from differences in life-history or phylogenetic lineage that are associated with provenance. Thus, selection...

  • Administrative principles and procedures of the agricultural experiment stations

    Creator:
    Zapata, Fabio Augusto
    Abstract:
    The successful agriculture of the United States is in part the result of the productive effort of the agricultural experiment stations. Students from different countries, throughout the world, have visited the United States to learn and observe the programs of the various experiment stations with the hope of being able...

  • The effect of seeding rate on yield and yield components of two winter wheat varieties

    Creator:
    Rana, Prakriti Shumshere Jung Bahadur
    Abstract:
    Wheat is an important cereal crop in the Willamette Valley of Oregon and the stiff-strawed, high-yielding varieties are the predominant types grown. Observation of the effect of seeding rates on the yield and yield components are useful in determining which of the components contributes most to the yield of a...

  • Preliminary design of an agricultural airplane

    Creator:
    Letzkus, Howard John
    Abstract:
    A design for an agricultural airplane is developed and evaluated, A biplane configuration was adopted since it provides better maneuverability and stall characteristics than a monoplane of comparable size and design simplicity. The airplane, powered by a 600-horse-power Pratt Whitney radial engine, was sized to carry a useful load of...

  • Solution of unsteady, two-dimensional, inviscid flows

    Creator:
    Kuo, Ying-Ming
    Abstract:
    The general theory of characteristics is reviewed for hyperbolic partial differential equations of n independent variables. The application of the theory of characteristics is made to unsteady, two-dimensional, rotational, inviscid flows; unsteady, two-dimensional, irrotational, inviscid flows; and unsteady, axial symmetric, inviscid flows. The characteristic surfaces and the compatibility relations are...

  • Effect of initial conditions on the convergence rate of the energy equation in Couette flow

    Creator:
    Seddigh, Foad
    Abstract:
    Computers are very efficient in handling the problems which deal with iteration. Numerical treatment of the unsteady energy equation is one sort of iteration. The convergence of the unsteady film coefficient, in two dimensional space, to its steady state value has been deduced by comparison of the results of the...

  • The effects of the herbicides Diquat and Dichlobenil on pond invertebrates

    Creator:
    Wilson, Dennis Carl
    Abstract:
    The acute toxicity of Diquat (1:1-ethylene-2:2' dipyridylium dibromide) and Dichlobenil (2, 6-dichlorobenzonitrile) to six selected pond invertebrates was determined using the median tolerance limit estimation method. Diquat was more toxic to the amphipod, Hyalella azeteca than to the aquatic insects Callibaetis, Limnephilus, Enallagma, Libellula, and Tendipedidae. The addition of mud...

  • Varietal resisitance of hops, Humulus lupulus (Linn.), to the two-spotted spider mite, Tetranychus urticae (Koch)

    Creator:
    Mayberry, Terrel Wilson
    Abstract:
    The purpose of this study was to determine the relative resistance of genetic lines of hops, Humulus lupulus (Linn.) to the two-spotted spider mite, Tetranychus urticae (Koch) in western Oregon. Approximately three-hundred genetic lines of hops were screened under insectory conditions during the 1965 growing season at Corvallis, Oregon. Reduction...

  • A seasonal study of sediment reworking by Neotrypaea californiensis in Yaquina Bay, Oregon

    Creator:
    Fritz, Cara E.
    Abstract:
    A year-long field study was undertaken to investigate the influence of a number of physical and biological factors, specifically temperature, organic carbon content, and shrimp population dynamics on sediment reworking rates by the ghost shrimp Neotrypaea calforniensis. Because of its role as a structuring agent in estuaries along the West...

  • Fingerprinting, reproductive behavior and pollinator dynamics of Buddleja davidii and interspecific hybrids

    Creator:
    Still, Cara M.
    Abstract:
    Buddleja davidii (butterfly bush) is a highly adaptable landscape plant known for pollinator attraction. Unfortunately, it is also regarded as an invasive plant in highly disturbed environments across the globe. It is an invasive species in Oregon, officially classified as a class B noxious weed in 2004. Currently the state...
