  • Studies on copper metabolism in the cotton rat Sigmondon hispidus texianus

    Creator:
    Milne, David Bayard
    Abstract:
    The effects of different levels of copper in the diet on growth rates, blood and liver copper concentrations, hemoglobin levels, and cytochrome c oxidase activities were determined in the cotton rat. The response of the cotton rat to different levels of copper was analagous to that of the common laboratory...

  • Conformation and reactivity studies of some bicyclo(3.3.1) nonane derivatives

    Creator:
    Sturmer, David Michael
    Abstract:
    New syntheses for 2-bicyclo(3.3.1)nonanone and 7-bicyclo-(3.3.1)nonen-2-one were developed. The saturated ketone was prepared from phenol and acrylonitrile via a novel intramolecular S[subscript N]2 cyclization process. A Friedel-Crafts cyclization of 3-(3-cyclohexenyl)propanoyl chloride permitted synthesis of the unsaturated ketone from 4-cyclohexene carboxaldehyde. The formation of the bicyclo(3.3.1)nonane rather than a bicyclo(3.2.2)nonane skeleton...

  • The effect of impurities on the gamma-ray coloration of potassium chloride crystals

    Creator:
    Hinks, David George
    Abstract:
    The incorporation of europium and dysprosium in potassium chloride crystals was investigated. The crystals were prepared by the Kyropoulos method from melts containing the rare-earth chlorides. The concentration of these rare-earth ions in the crystals was determined by neutron-activation analysis. The distribution coefficient of europium and dysprosium between the molten...

  • Studies in molybdenum oxide catalysts : I. Metal vapor reactions of molybdenum trioxide with various alkoxy silanes : II. Investigation of oxide supported molybdenum catalysts prepared from molybdenum(VI)dioxodiethoxide

    Creator:
    Huffman, David Earl
    Abstract:
    The cocondensation reactions of molybdenum trioxide vapor with tetraalkoxysilanes, trimethylalkoxysilanes, and hexamethyldisiloxane at -196°C were investigated. The products from the metal vapor reactions of tetramethoxysilane, tetraethoxysilane, and tetrapropoxysilane were characterized as molybdenum(VI)dioxodialkoxy compounds. The isolated compounds were found to be polymeric in the solid state by bridging through alkoxide groups....

  • Steroid dialkylcarbene reactions

    Creator:
    Dixon, Dale David
    Abstract:
    Steroid carbenes have been investigated as synthetic intermediates. Basic decomposition of 4-en-3-one tosylhydrazones (and other A-ring systems) gives varying amounts of 2, 4-dienes, and solvent derived products with diglyme, heptane, tetrachloroethylene, carbon tetrachloride, benzene and cyclohexene. A method for separating complex product mixtures was developed and a study of the...

  • A chemical study of the minerals from L-6 chondritic meteorites

    Creator:
    Curtis, David Ballantyne
    Abstract:
    Major and minor minerals have been separated from three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin), and Leedey). Olivine, hypersthene, diopside, feldspar, troilite, chromite, phosphate minerals, and metallic minerals were analyzed for major, minor and trace elements using instrumental neutron activation analysis and radiochemical neutron activation analysis techniques. Concentrations df the...

  • Application of a weighted Dice Similarity Coefficient (DSC) for Structure Comparison in Radiation Treatment Planning

    Creator:
    Fried, Zachary
    Abstract:
    Coded metrics that compare representations of structures within the human body to evaluate their similarity are considered useful for planning radiation therapy on cancer targets. However, existing metrics fail to take into account the dose of radiation that will be received by both the target, and surrounding non-target tissue, during...

  • The Local Structure of Functional Electroceramics

    Creator:
    Culbertson, Charles M.
    Abstract:
    This work investigates the relationship between the local structure and physical properties of a set of classical (MgTiO3, CaTiO3, SrTiO3, and BaTiO3) and complex ((1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3[BZT-BCT], Na0.5Bi0.5TiO3 [NBT]) perovskite electroceramics. The materials in this work were synthesized via standard solid state ceramic synthesis, the structure was investigated through a number of...

  • Approaches to the total synthesis of verrucarol

    Creator:
    Hill, David E. (David Edwin) 1954-
    Abstract:
    Verrucarol is the sesquiterpene portion of a number of macrocyclic di- and triesters of potential medicinal importance. In this study, a novel approach to the synthesis of this fungal metabolite is presented. An A-B-C route was investigated in which C-3 and C-4 of the C-ring were emplaced using a [2+2]...
