  • Deposition and characterization of transition metal oxides from aqueous solution

    Creator:
    Betterton, Sharon A.
    Abstract:
    The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...

  • Multiple pest suppression with cover crops in strawberry

    Creator:
    Datta, Braja Bandhu
    Abstract:
    The experiment was conducted to compare multiple pest (weed, soil arthropod and diseases) suppression by cereal cover crops in 'Selva' and 'Totem' strawberry. In addition, perlite was used to compare improvement of soil and root aeration which might modify strawberry black root rot complex. Small-seeded summer annual weeds were suppressed...

  • Combustion mechanisms in wood fired boilers

    Creator:
    Tuttle, Kenneth Lewis
    Abstract:
    A program of research has been established at Oregon State University to study wood residue combustion using an experimental spreader-stoker combustor. This research was conducted to increase the understanding of combustion occurring in wood fired boilers. Using Douglas Fir screened to 3/8-3/4 inches, two 4x4 factorial experiments were conducted varying...

  • Recent policy change in developed-site recreation management in two federal agencies

    Creator:
    Bradford, Paul F.
    Abstract:
    In the past 3-5 years, two federal agencies, the Forest Service (FS) and the National Park Service (NPS), have initiated pilot programs in concessioner-operation of developed-site government recreation facilities, specifically family campgrounds and related facilities. These programs have been generally successful by agency measure, and consequently, both agencies have modified...

  • Managing Microdochium Patch Using Non-Traditional Fungicides on Annual Bluegrass Putting Greens

    Creator:
    Mattox, Clint M.
    Abstract:
    Currently, fungicide applications are the predominant method of control for the cool weather pathogen Microdochium patch (Microdochium nivale). Increasing pesticide restrictions have generated concern regarding management of Microdochium patch. Three separate field trials exploring non-traditional fungicides were conducted between 2013 and 2015 on an annual bluegrass (Poa annua L.) sand-based...

  • Conditioning bunchgrass on elk winter range

    Creator:
    Westenskow, Kathy Jo
    Abstract:
    Research was conducted near the Starkey Experimental Forest and Range in northeastern Oregon. Effects of defoliating bluebunch wheatgrass (Agropyron spicatum (Pursh) Scribn. and Smith) to increase the quality of regrowth available on elk (Cervus elaphus nelsoni) winter range were studied from 1988 through 1990. Clipping treatments were implemented to condition...

  • Studies of rainbow trout Ki-ras gene : sequencing, aflatoxin B1 binding, and chromatin structure

    Creator:
    Liang, Xiaoshan
    Abstract:
    Characterization of the 5' flanking region of rainbow trout ki-ras gene was begun with the cloning and sequencing of this region by the inverse PCR technique and dideoxynucleotide chain termination method. In total, a nucleotide sequence of 1080 bp upstream from the first coding ATG was sequenced. Although this region...

  • Relationships of green-tree retention following timber harvest to forest growth and species composition in the western Cascade Mountains

    Creator:
    Rose, Coulter R.
    Abstract:
    National Forest management in the Pacific Northwest is shifting from a focus on commodity production to ecosystem management, in which the health of the entire forest ecosystem is considered, rather than that of a few key species. Ecosystem management includes retention of some live trees following timber harvest (green-tree retention)...

    Creator:
    Hussain, Imdad
    Abstract:
    Nine feeding trials and four laboratory scale experiments were conducted in this study. The study consisted of: (1) use of grass straw:corn juice (CJ) silages with fishmeal and/or alfalfa hay supplementation in beef heifers, sheep, pregnant dairy heifers, water buffaloes and Hereford cows; (2) use of cull onions:grass straw silages...
