  • The copepods in a collection from the southern coast of Oregon, 1963

    Creator:
    Lee, Wen-yuh
    Abstract:
    Plankton samples for this present study were collected from an area off the southern Oregon coast, extending westward to about 83 kilometers offshore. Over this sampling area, 41 species of adult copepods were identified, including representatives of 26 genera and 17 families. The total abundance averaged 550/m³. Population densities of...

  • Density separation of clay minerals

    Creator:
    Nelsen, Terry A.
    Abstract:
    Illite, chlorite, montmorillonite and kaolinite, as well as natural marine sediments and mixtures of the standards were subjected to density separation by centrifugation in a linear heavy-liquid gradient. The density layers yielded by centrifugation were recovered and analyzed by X-ray diffraction. Separates were not monomineralic but rather were polymineralic usually...

  • Steady- and unsteady-state longitudinal water permeability of western hemlock

    Creator:
    Lancaster, Eugene Peter
    Abstract:
    A decreasing rate of flow was observed (after sufficient air and particulate matter were removed from the wood and water) under steady-state conditions for green western hemlock sapwood. The decrease is theorized to be due to viscoelastic behavior of pit membranes. An unsteady-state procedure for determining longitudinal liquid permeability of...
