  • Using p-adic valuations to decrease computational error

    Creator:
    Limmer, Douglas J.
    Abstract:
    The standard way of representing numbers on computers gives rise to errors which increase as computations progress. Using p-adic valuations can reduce error accumulation. Valuation theory tells us that p-adic and standard valuations cannot be directly compared. The p-adic valuation can, however, be used in an indirect way. This gives...

  • Design, fabrication and characterization of complementary heterojunction field effect transistors

    Creator:
    McMahon, Terry E. (Terry Edwin), 1963-
    Abstract:
    Complementary delta-doped AlGaAs/GaAs Heterojunction Field Effect Transistor (CHFET) devices and circuits were fabricated using MBE and a 2μ non-planar gate recess process. Several schemes were used in an attempt to improve the performance of the p-channel HFETs. These included delta-doping, carbon-doping and dipole-doping. Circuits and individual n- and p- channel...

  • Development of in vitro lily scale budlets as related to virus elimination

    Creator:
    Ruttum, Joanne C.
    Abstract:
    Lily hybrids vary in their ability to produce virus-free (VF) bulblets when grown from virus-infected scales in tissue culture. Asiatic hybrids typically produce a higher percentage of in vitro VF scale bulblets than do Lilium longiflorum cultivars. Three hypotheses concerning the cause of this variation are tested on five lily...

  • Mark Fuhrman's Murder In Brentwood : A Rhetorical Criticism of Apologia as Masculine Facework

    Creator:
    Kearney, Melva J.
    Abstract:
    Apologia is a rhetorical genre of self-defense. As such, apologetic discourse involves a response to an attack upon an individual's character or worth as a human being. Los Angeles Police Detective Mark Fuhrman encountered such a attack during the 0.J. Simpson murder trial. The purpose of this analysis is to...

  • Breeding bird community composition in relation to riparian vegetation structure in grazed habitats

    Creator:
    Sanders, Todd Alan
    Abstract:
    Riparian zones provide habitat for breeding birds in the semiarid western United States; however, there are few data available that address the effects of livestock grazing strategies on riparian habitats and avian communities. Documenting avian community composition in different riparian vegetation communities and relating vegetation communities to livestock grazing strategies...

  • Abundance and habitat associations of Washington ground squirrels in north-central Oregon

    Creator:
    Greene, Eric
    Abstract:
    Much of the Columbia River Basin has been cultivated for agriculture, which has reduced and fragmented the native shrub-steppe habitats. As a result, the range of the Washington ground squirrel (Spermophilus washingtoni) has been significantly reduced, prompting the states of Washington and Oregon to review their status. Consequently, I investigated...

  • Effect of dietary fluoride on selenite toxicity in the rat

    Creator:
    Yu, Qing, 1966-
    Abstract:
    Two factorial experiments were conducted to determine if high dietary fluoride would inhibit selenite toxicity in rats. In each study, two levels of selenite (0.05 and 5 mg/kg diet) were matched against two levels of fluoride (1 and 150 mg/kg diet) for either 6 or 8 weeks. Fluoride failed to...

    Juergens, Cheryl A.
    Abstract:
    In competitive swimming a spread in time of only 0.10, and 0.16 seconds constituted the difference between finishing second and seventh, and first and eighth, respectively, in the women's 50 yard freestyle at the 1993 NCAA Division III National Swimming & Diving Championships. Based on data collected over a period...

  • Introgression between jointed goatgrass (Aegilops cylindrica) and wheat (Triticum aestivum)

    Creator:
    Snyder, Jeremy R.
    Abstract:
    Hybrids between wheat and jointed goatgrass have long been presumed to be sterile; however, seed were found on hybrid plants in 1990. Field studies were conducted in 1995 and repeated in 1996. One to ten hybrid plants were planted in variable populations of wheat and jointed goatgrass to determine the...

  • Counterfeit arcadias : Nathaniel Hawthorne's materialist response to the culture of reform

    Creator:
    White, Andrew
    Abstract:
    Nathaniel Hawthorne lived and wrote in an age of reform efforts, and the progressive movement with which he was most familiar was Transcendentalism. However, he was not sympathetic with Emerson's idealism, a sentiment which comes out in his fiction in way of critique. Throughout Hawthorne's work there is an emphasis...
