  • Trends in riparian vegetation regrowth following timber harvesting in western Oregon watersheds

    Creator:
    Summers, Richard P.
    Abstract:
    This study investigated the development of riparian zone vegetation at varying stand ages from one to 29 years following clearcut timber harvesting in western Oregon. Vegetation was classified into three layers for observation including the ground (less than 13 cm), the understory (less than 2.5 m), and the overstory (greater...

  • The dynamic shear moduli of blubber for selected large whale species

    Creator:
    Summers, Michael P.
    Abstract:
    Whale blubber is the insular tissue layer located between the dermis and the superficial fascia layer which sheathes the whale's musculature. It is made up of a lipid matrix ramified with strong, structural collagen and elastic fiber bundles, but little is known of its mechanical properties. Knowing these properties adds...

  • Automation of a low-temperature calorimeter

    Creator:
    Beyer, R. P. (Richard P.)
    Abstract:
    An adiabatic calorimeter operating over the range 5 to 300 K has been automated. Instrumentation includes computer controlled data acquisition, a low-thermal emf multiplexer for switching low-level dc signals, and automatic analog shield controls. Temperature measurements are made with platinum and germanium resistance thermometers, and the thermometer resistances are determined...

  • Direct shear testing of UO₂ sphere-pac nuclear reactor fuel

    Creator:
    Jenks, Richard P.
    Abstract:
    The design, development, and utilization of a direct shear test apparatus is presented in this thesis. The effectiveness of the device for determining the friction angle stress state parameter is studied. Two materials, alumina and uranium dioxide, were tested. Alumina microspheres were employed in the initial experiments to simulate the...

  • Incorporation of ¹⁵NO₃ into amino acids of Douglas-fir xylem sap

    Creator:
    Sandstrom, Richard P.
    Abstract:
    Roots are considered to be the major production site of amino acids that appear in the xylem sap of conifers. The carbon skeleton of amino acids is derived from photosynthetically reduced carbon dioxide while the nitrogen is derived from the inorganic forms taken up by the roots. An experiment was...
