  • DyhrmanRF Map2.pdf

    Creator:
    Dyhrman, Richard F.
    Abstract:
    The thesis area is located southwest of Portland, Oregon, in the Western Cascades. In the area are volcaniclastic rocks and lava flows that range in composition from basaltic andesite to dacite. The dominant volcaniclastic rock type is thin intracanyon ash-flow tuff. The dominant lava flows are a thick sequence of...

  • An investigation of the effects of nutritional status on the action of insulin in rainbow trout (Salmo gairdneri)

    Creator:
    Ablett, Richard F.
    Abstract:
    Three studies were conducted to evaluate the relationship between insulin and nutritional parameters in rainbow trout. In the first study effects on growth parameters and tissue composition of rainbow trout were investigated following injection of bovine insulin at two dose levels every 48 hr for 56 days. In addition, [¹⁴C]-leucine...

  • Attenuation of rainfall intensity by forest canopies

    Creator:
    Keim, Richard F.
    Abstract:
    Interception of precipitation by forest canopies has been found previously to reduce rainfall intensity, but this effect is poorly understood. The goal of this research is to quantify the attenuation of rainfall intensity by forest canopy interception, with the specific objective of estimating the contribution of this attenuation to hillslope...

  • Coping With an Increasing Import Base: A Case Study of the Southeast U.S. Shrimp Processing Industry

    Creator:
    Keithly, Walter, Diop, Hamady, and Kazmierczak, Richard F.
    Abstract:
    It is well known that world production of shrimp, particularly farm-raised product, has increased significantly since the early-to-mid 1980's and that much of the product is directed to the U.S. market. Less well known is the fact that the product composition of the U.S. imported product (e.g., headless shell-on, peeled)...
