  • Pyrenophora tritici-repentis : investigation of factors that contribute to pathogenicity

    Creator:
    Holman, Thomas W.
    Abstract:
    Pyrenophora tritici-repentis (Ptr) is the necrotrophic fungus responsible for tan spot of wheat (Triticum aestivum). Ptr causes disease on susceptible wheat cultivars through the production and secretion of host-selective toxins (HSTs). HSTs are compounds that are only known to be produced by fungi and considered to be primary determinants of...

  • A study of some physiological properties of ovine and bovine utero-ovarian arteries

    Creator:
    Kuhl, Lynda Marie
    Abstract:
    The utero-ovarian vasculature of domestic animals has been a popular research subject, especially concerning the roles of the uteroovarian artery and vein in the unilateral luteolytic phenomenon demonstrated in these animals. No reports in the literature, however, have been found regarding the smooth muscle physiology of these vessels. The present...

  • Consumers' attitude toward metric conversion for clothing sizes related to selected variables

    Creator:
    McCauley, Lynda Dianne
    Abstract:
    The purpose of the study was to explore the possible acceptance of metric conversion for clothing sizes and sizing standardization by a selected sample of female ready-to-wear clothing consumers. A questionnaire was designed to elicit consumer's positive or negative attitudes toward metric conversion for clothing sizes and sizing standardization. The...

  • Winter cover cropping effects on integrative biological indicators of soil quality

    Creator:
    Ndiaye, Evelyne L.
    Abstract:
    Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...

  • Characteristics of bradyrhizobium sp. recovered from Oregon soils

    Creator:
    Cheng, Hsin-hua
    Abstract:
    Although the biology of Bradyrhizobium has been studied for almost one hundred years, virtually nothing is known about the ecology and genetic variation in natural soil populations of this genus. The majority of information has been obtained from studies of one species, Bradyrhizobium japonicum, and the diversity within soil populations...

  • Bioavailability of vitamin B-6 from test foods and metabolism of vitamin B-6 in men receiving supplementary pyridoxine

    Creator:
    Wang, Kuen Wu
    Abstract:
    The bioavailability of vitamin B-6 from four selected foods was investigated in five men, aged 22 to 25 years, who were receiving a pyridoxine supplement. The subjects received a constant diet containing 1.34 mg of vitamin B-6 throughout this five-week study, except on Saturdays and Sundays when they ate their...

  • An investigation of the effects of information displays on human forecasting performance

    Creator:
    Tirakitti, Sunthorn
    Abstract:
    With increasing frequency man is required to operate as a controller of complex processes. Although his ability to operate quickly varying processes has been extensively studied, his ability to control slowly varying processes has been largely neglected. Often his performance in such tasks is dependent upon his ability to forecast...

  • A Bayesian model for the determination of optimal sampling intervals

    Creator:
    Paradis, Garry Lynn
    Abstract:
    There are a nearly unlimited number of situations in which the status of time-varying processes must be updated. The monitoring of these processes usually occurs at periodic intervals. Whether the monitoring is performed by man or machine, a decision must be made regarding the frequency of these activities, that is,...

  • Factors affecting establishment and germination of upland prairie species of conservation concern in the Willamette Valley, Oregon

    Creator:
    Jones, Katherine D.
    Abstract:
    Identifying mechanisms that determine who lives and dies is the first step in developing successful restoration techniques for rare species and endangered habitats. We studied interactions that affect establishment of native plant forbs of conservation concern at the seedling stage to support the theoretical basis for restoration activities in Pacific...

  • Using local climate to explain temporal variation in rare plant populations

    Creator:
    Pfingsten, Ian A.
    Abstract:
    Increased temperatures due to anthropogenic-induced climate change may raise the threat of extinction for taxa with sessile life histories (e.g., plants) in the near future. Linking climate change models to demographic models may provide useful insights into the potential effects of environmental changes on rare plants, and therefore aid in...
