  • The relationship of estradiol to embryo-maternal interactions in the llama

    Creator:
    Powell, Susan A.
    Abstract:
    In the first experiment, estradiol production was measured in cultured embryos collected on Days 7, 9, 11, 13 and 15 post-mating. Estradiol was detected in Day 7 embryos and production increased approximately 50-fold (P<0.05) in medium recovered from Day 13 compared to Day 11 embryos and was greatest (P<0.05) from...

  • Design of a 14-bit continuous-time Delta-Sigma A/D modulator with 2.5MHz signal bandwidth

    Creator:
    Li, Zhimin
    Abstract:
    In recent years, there has been growing interest in both industry and academia to use continuous-time (CT) Δ-Σ A/D converters for wideband wireless and wireline communication applications. So far no reported CT Δ-Σ A/D modulator achieves 14-bit or higher dynamic range (DR) with more than 2MHz signal bandwidth (equivalently 4MS/s)....

  • Cumulative effects of land use on salmon habitat in southwest Oregon coastal streams

    Creator:
    Frissell, Christopher Andrew, 1960-
    Abstract:
    As part of a hierarchical approach to classifying watersheds and stream habitats based on geomorphic and geologic criteria, we defined ten classes of fluvial and lacustrine habitats at the scale of valley segments. Valley segments are landscape units which encompass surface waters and the adjacent floodplains and hillslopes with which...

  • DNA fingerprinting and genome mapping in meadowfoam

    Creator:
    Katengam, Sureeporn
    Abstract:
    Marker information in the new oilseed crop, meadowfoam, is limited. Molecular markers to facilitate meadowfoam breeding and cultivar improvement are not available. The knowledge of genetic relationships among recent germplasm is not known. The objectives of this study were (i) to gain an understanding of genetic diversity and relationship patterns...

  • The predictive relationship of religiosity to readiness to change in addiction recovery

    Creator:
    Mandsager, Naomi A.
    Abstract:
    The prevalence of addiction in society has called researchers, educators, policy makers, and clinicians to examine and research causes and treatment approaches to address the manifold problems addictions present individuals and society alike. There are many theoretical approaches to understanding addiction and the behavior change processes that lead from addiction...

  • Harlequin duck demography during winter in Prince William Sound, Alaska : effects of the Exxon Valdez oil spill

    Creator:
    Esler, Daniel
    Abstract:
    The 1989 Exxon Valdez oil spill was a major perturbation of nearshore habitats of Prince William Sound, a wintering area for harlequin ducks (Histrionicus histrionicus). This research was designed to evaluate harlequin duck population recovery from the oil spill from 1995 to 1998, using a demographic approach to assess both...

  • Culturing uncultured environmental microorganisms

    Creator:
    Connon, Stephanie A.
    Abstract:
    Research on natural environments, over the last decade, is replete with microbial diversity studies that used culture-independent approaches. The cloning and sequencing of the 16S rRNA genes has been the driving force in the expansion of awareness about the great diversity of previously undiscovered microorganisms. Well-known uncultured groups of microorganisms...

  • Calanoid copepod diet in an upwelling system : phagotrophic protists vs. phytoplankton

    Creator:
    Fessenden, Lynne M.
    Abstract:
    Calanoid copepod diet was investigated in Oregon coastal waters to determine the trophic significance of phagotrophic protists as copepod prey within an ecosystem where the microplankton biomass is typically dominated by large diatoms. Prior to and during the 1991 upwelling season, clearance rates on phytoplankton and phagotrophic ciliates were measured...

  • Molecular and physiological aspects of maize embryo maturation

    Creator:
    White, Constance N.
    Abstract:
    Experiments were performed to assess regulatory factors governing maize embryo maturation and vivipary. Both visual and molecular markers of embryo development were used to examine the roles of the hormones abscisic acid (ABA) and gibberellins (GAs), as well as water stress in governing transit from early embryogeny to maturation-phase development....
