  • Polybenzimidazole synthesis from compounds with sulfonate ester linkages

    Creator:
    Seckin, Turgay
    Abstract:
    This investigation of polybenzimidazole synthesis involved the two-stage low temperature solution polymerization of dialdehydes, One-step polycondensation of dialdehydes, two-stage melt polycondensation of diesters, and one-step solution polycondensation of diesters with 3,3'-diaminobenzidine. Dialdehyde or diester monomers were prepared which contained aromatic units which were hooked together with sulfonate linkages. Polymerization of...

  • Pharmacological characterization of the porcine atrial A₁ adenosine receptor

    Creator:
    Leid, Mark
    Abstract:
    Cardiac A₁ adenosine receptors mediate cardioinhibitory properties of adenosine and structural congeners. The objective of these studies was to increase our understanding of molecular processes involved in ligand interactions with receptors mediating cardioinhibitory effects of adenosine and the interactions of these receptors with guanine nucleotide binding regulatory proteins. Porcine atrial...

  • In vitro hormonal and metabolic control of bovine mammary glucose 6-phosphate dehydrogenase activity

    Creator:
    Young, Allen Jack
    Abstract:
    Two studies were conducted to determine the in vitro metabolic and hormonal effects on glucose 6-phosphate dehydrogenase activity (G6PD) in bovine mammary explants. Study I was conducted to determine the effects of palmitoyl CoA (5 and 25 uM), acetate (1 and 10 mM), spermidine (0.4 mM) and putrescine (0.4 mM)...

  • The effect of lasalocid on fall calving beef cows

    Creator:
    Hopman, Bruce T.
    Abstract:
    Forty-two fall-calving crossbred cows were equally allotted to six pens of seven cow-calf pairs each. Two treatments (0 and 200 mg lasalocid/head/day) with three replications were used to determine the effects of lasalocid on fall-calving beef cows. The cows were fed grass hay, haylage and pasture ad libitum. The cow-calf...

  • Silvicultural impacts of sheep grazing in Oregon's Coast Range

    Creator:
    Leininger, Wayne C.
    Abstract:
    A three-year investigation was conducted during 1980-1982 to evaluate the potential of using herded sheep as a silvicultural tool to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest in May soon after bud break. Averaged over the 2 years of grazing,...

  • Changes in the self-esteem, parental attitude, and generalized contentment among teen mothers enrolled in a parent program

    Creator:
    Guiles-Fellez, Cynthia Lynn
    Abstract:
    Adolescent pregnancy is a serious problem which creates social and emotional consequences for 1 in 10 teenaged girls and their families. Although the severity of the problem has been well documented in the literature, few empirical investigations have been conducted to expand information or to aid in the understanding of...

  • Dietary fish meal and the incidence of sudden death syndrome in broiler chickens

    Creator:
    Wu, Yea-ching
    Abstract:
    Five experiments were conducted to investigate the effect of dietary fish meal on the incidence of Sudden Death Syndrome (SDS) in broiler chickens. Growth, feed efficiency, total mortality and mortality due to SDS were evaluated. Necropsy examination was performed on broilers suspected of dying from SDS. Liver lipid and fatty...

  • Analysis of variability of some forest soils in southwestern Oregon

    Creator:
    Wicherski, Bruce P.
    Abstract:
    The variability of selected physical, chemical, and morphological soil properties in two landtype mapping units on'the Rogue River National Forest in southwestern Oregon was studied. The objectives of the study were (i) to quantify soil variability in several soil resource inventory mapping units, (ii) to explore methods of describing soil...

  • An evaluation of strategies for hedging feeder cattle in the Pacific Northwest

    Creator:
    Gatti, Andrew Leo
    Abstract:
    Over the past decade, feeder cattle backgrounders in the Pacific Northwest have been subject to sharp price fluctuations for their output. The result has been variable profits and losses. This situation creates a need for management and marketing techniques which can provide Pacific Northwest cattle ranchers with protection against price...

  • Mesurol (methiocarb) residues in grapes and wine and their possible effects on fermentation and wine quality

    Creator:
    Miller, Frederick Kenton
    Abstract:
    Wines were made from Pinot Noir and White Riesling grapes which had received field application rates of 2 and 4 lb./acre of the experimental bird repellent Mesurol (methiocarb or 3, 5 dimethyl- 4(methylthio)phenylmethylcarbamate). In addition, Pinot Noir must and press juice and White Riesling press juice were fortified with 15...
