  • Biological durability of cross-laminated timber connections

    Creator:
    Udele, Kenneth E.
    Abstract:
    Mass timber (MT) offers viable eco-conscious solutions within the building industry, with its high strength ratings, dimensional stability, light weight and renewable nature enhancing its status as a low carbon alternative to conventional building materials like steel and concrete. Moisture intrusion, coupled with the inherent organic nature of wood pose...

  • Influence of range improvement practices on composition, production, and utilization of Artemisia deer winter range in central Oregon

    Creator:
    Urness, Philip J.
    Abstract:
    Recent emphasis on range improvement of sagebrush-bunch-grass types in Oregon has underscored the need for better understanding of their importance to deer winter range management. The objectives of this study were to evaluate the impact of various sagebrush control practices on the composition, production, and utilization of deer forage plants...

  • Multi-metal equilibrium sorption and transport modeling for copper, chromium, and arsenic in an iron oxide-coated sand, synthetic groundwater system

    Creator:
    Osathaphan, Khemarath
    Abstract:
    The mixed metal compound, Chromated Copper Arsenate, or CCA, has been widely used as a wood preservative. The metal ions in CCA, CrO²⁻₄, Cu²⁺, and AsO³⁻₄, have been found in contaminated surface and subsurface soils and groundwater nearby some wood preservative facilities and nearby wood structures. Iron oxides are a...

  • Multi-Scale Approach to Evaluating Moisture Durability of Wood-Based Composites

    Creator:
    Way, Daniel J.
    Abstract:
    The majority of low-rise residential structures in the U.S. are constructed with wood. Wood-based composites are primary building materials in these structures, used as structural sheathing, joists, and beam components. Wood composites are susceptible to degradation upon exposure to high levels of moisture. Moisture durability is routinely assessed with accelerated...

  • Minimum vitamin requirements and vitamin interrelationships for growth in Japanese quail (Coturnix coturnix japonica)

    Creator:
    Ramachandran, Vama
    Abstract:
    A series of 17 experiments was conducted to investigate the minimum vitamin requirement and vitamin interrelationship for growth of Coturnix coturnix japonica to two weeks of age using a glucose monohydrate-isolated soybean protein diet. The first phase involved two preliminary trials. The first trial consisted of four treatments with the...

  • Pathogenesis and intertree transmission of Verticicladiella wageneri in Douglas-fir (Pseudotsuga menziesii)

    Creator:
    Hessburg, Paul F.
    Abstract:
    Verticicladiella wageneri Kendr. is a vascular wilt pathogen of Douglas-fir in the Pacific Northwest, The disease is characterized by black staining of colonized sapwood; crown symptoms are those typical of a wilting syndrome. Histopathological studies revealed that the pathogen is limited to the xylem but causes vascular dysfunction in both...

  • Blood Processing Technologies for Cryopreserved Transfusion Products and Extracorporeal Treatment Applications

    Creator:
    Lahmann, John M.
    Abstract:
    There is a significant need for technological advancement in blood processing. New technologies in rapid processing of frozen blood products could significantly improve management of the blood supply chain in the United States by enabling on-demand use of frozen blood products that can be stored for 10 years instead of...

  • Characterization of load transfer in wood-based composites

    Creator:
    Schwarzkopf, Matthew John
    Abstract:
    The mechanical performance of composite materials is determined by the mechanical properties of their individual components and the effective load transfer between these components. Binders are commonly used to bond composite components together and to provide effective load transfer between them. In wood-based composites the binder-component load transfer occurs at...

  • Morphology and genesis of Gray Podzolic soils in Thailand

    Creator:
    Rojanasoonthon, Santhad
    Abstract:
    Nine Gray Podzolic soils from different physiographic regions of Thailand were studied to determine their characteristics and genesis in relation to their parent materials, land form, pedogenic environment, classification and management. The clay was characterized by X-ray diffraction and standard chemical and physical analyses were performed. Mineralogy of the light...

    Abstract:
    Herein, a program of research is detailed related to transport through the Si metal oxide semiconductor (MOS) quantum dots fabricated in a process flow compatible with modern ULSI (ultra large scale integrated circuit). Silicon quantum dots were fabricated by placing split gates within a MOSFET structure. Quantum dots of several...
