  • Microbial and biochemical dynamics of ectomycorrhizal mat and non-mat forest soils

    Creator:
    Kluber, Laurel A.
    Abstract:
    Dense hyphal mats formed by ectomycorrhizal (EcM) fungi are prominent features in Douglas-fir (Pseudotsuga menziesii) forest soils and have been estimated to cover up to 40% of the forest floor in some stands. Although previous studies have examined various aspects of EcM fungi, little is known about their associated microbial...

  • Studies on the etiology and epidemiology of bull's eye rot of pears

    Creator:
    Henriquez, Jose Luis, 1961-
    Abstract:
    The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

  • Water Efficiency for Urban Landscapes in Semi-Arid Environments

    Creator:
    Martinson, Richard W.
    Abstract:
    Urban landscape water use is increasingly a focus of water conservation efforts. This is especially true in the arid and semi-arid regions of the western United States where increased demand, environmental concerns, and extended periods of drought have created chronic water shortages. However, until recently, little attention has been paid...

  • Environmental Mixtures and Selected Health Outcomes in the US Population

    Creator:
    Przybyla, Jennifer
    Abstract:
    The human health effects of exposure to numerous single environmental contaminants have been well characterized. Yet, biomonitoring studies have detected multiple environmental chemicals in humans, highlighting the need to investigate the health effects of exposure to multiple environmental chemicals. Environmental data is highly complex, therefore current methods of defining environmental...

  • Design of a Self-Regulating Deep Space Nuclear Reactor

    Creator:
    Robinson, Matthew Loren
    Abstract:
    An enabling technology for long duration, deep space missions is the availability of a high power, long-lived power supply. The goal of this work is the design of a self-regulating deep space nuclear reactor. The design objectives are to produce 250 kWth for a 25-year period using the presence of...

  • Whole farm case studies : a how-to guide

    Creator:
    Murray, Helene
    Abstract:
    Calls for increased farmer involvement in research and extension programs have been numerous and well supported. One approach to integrate the collective knowledge and experience of agricultural scientists and farmers is through whole farm case studies (WFCS). An interdisciplinary team of 34 research and extension personnel at Oregon and Washington...

  • Examination of the role host-selective toxins play in fungal-plant interactions

    Creator:
    Andrie, Rachael M.
    Abstract:
    Pyrenophora tritici-repentis, causal agent of tan spot of wheat, produces multiple host-selective toxins (HSTs), including Ptr ToxA, encoded for by ToxA, Ptr ToxB, encoded for by ToxB, and Ptr ToxC. Variable distribution of these three HSTs among different isolates of P. tritici-repentis, both singularly and in all possible combinations, defines...

  • Interactions of auxin with ethylene and gravity in regulating growth and development in tomato (Lycopersicon esculentum, Mill.)

    Creator:
    Madlung, Andreas
    Abstract:
    Plant growth, development, and environmental responsiveness are dependent on hormone-induced gene expression. This dissertation reports multiple interactions between the plant hormones auxin and ethylene and investigates their contribution to the gravitropic response, elongation growth, adventitious root formation, callus and tracheary element initiation and growth, and flower development. Four mutants of...

  • Strategies for machine harvesting of mature coffee (Coffea arabica L.) fruits

    Creator:
    Tongumpai, Peeradet
    Abstract:
    Greenhouse and field grown coffee plants were used to study the synchronization of flowering and fruiting. The purpose of these studies was to develop methods of improving the selective harvesting of mature coffee fruits by machine. The studies were divided into 4 parts: 1) Synchronization of flowering, 2) Synchronization of...
