  • Hydrology and delineation in four wetlands in the Oregon Cascades

    Creator:
    MacLeod, Norman A.
    Abstract:
    Four wetland sites were identified and delineated in Silver Falls State Park, Oregon using procedures outlined in the 1989 Federal Manual for the Identification and Delineation of Jurisdictional Wetlands and subsequently monitored for a ten month period. A network of 225 shallow (32") wells was installed throughout the sites to...

  • Development of a hybrid modeling framework for intensively managed Douglas-fir plantations in the Pacific Northwest

    Creator:
    Weiskittel, Aaron R.
    Abstract:
    Forest growth models in the Pacific Northwest are predominantly empirical. Predictions of yield under alternative silvicultural regimes cannot rely completely on field trials; yet empirical growth models are often inadequate for extrapolating untested regimes and genotypes. The limitations of current models include (1) long time-steps (e.g. 5-10 years); (2) insufficient...

  • Wide band gap semiconductors and insulators : synthesis, processing and characterization

    Creator:
    Hersh, Peter A.
    Abstract:
    The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

  • Decision support systems for forest biodiversity management : a review of tools and an analytical-deliberative framework for understanding their successful application

    Creator:
    Gordon, Sean N.
    Abstract:
    The complexity of forest management has increased with the scope of resources of concern and the level of scrutiny from stakeholders. The design and use of specialized computer software, often referred to as “decision support systems” (DSS), is one method for helping managers deal with this complexity. DSS have proven...

  • Hydrographic data from Oregon coastal waters : June 1960 through May 1961

    Creator:
    Wyatt, Bruce and Kujala, Norman F.
    Abstract:
    This is the third data report of a study designed to determine the current patterns and water mass characteristics along the Oregon coast. The first report covered the period July 1958 to July 1959 (Wyatt and Callaway, 1961). During that year observations were taken to a maximum depth of 30...

  • Luminescent sulfides and solution-deposited oxide thin films

    Creator:
    Anderson, Jeremy T.
    Abstract:
    Solid state luminescent sulfides are prepared as powders in order to elucidate the relationship between structure and light emission. While the sulfides studied in this dissertation are known phosphors, materials are investigated in a variety of new ways. Elementary properties and structures of MgS are reviewed, and preparation of MgS...

  • The effects of site preparation on native forb establishment in a wet prairie, Willamette Valley, Oregon

    Creator:
    Norman, Katherine N.
    Abstract:
    Wetlands and wet prairies are economically and environmentally valuable ecosystems, but many have been degraded or converted to other uses. As human understanding of wetlands' value has increased, restoration efforts have grown correspondingly. Restoration attempts use a diversity of methods, which often include seeding with native plant species. This thesis...

  • High quantum-yield phosphors via quantum splitting and upconversion

    Creator:
    Jeong, Joayoung
    Abstract:
    The Gd3+ ion has been used to induce quantum splitting in luminescent materials by using cross-relaxation energy transfer (CRET). In Nd:LiGdF4, quantum splitting results from a two-step CRET between Gd3+ and Nd3+, first involving a transition 6G→6I on Gd3+ and an excitation within the 4f3 configuration of Nd3+ followed by...

  • Solution deposition and characterization of the thin film inorganic materials

    Creator:
    Özmen, Bahar
    Abstract:
    The general emphasis of this work has been synthesis, characterization, and applications of n- and p-type inorganic oxide thin films that are deposited from solutions. In particular, a study of n-type transparent semiconductor films of tin (IV) oxide and zinc-doped tin (IV) oxide has been performed by spin coating. Solution...
