  • Interconversions of monoterpenes in peppermint

    Creator:
    Burbott, Alice Joyce
    Abstract:
    The analysis of the distribution of monoterpenes through the leaf pairs of a single shoot of Mentha piperita supports Reitsema's contention that the first terpenes formed are unsaturated ketones and that saturated terpenes are produced from these. The growth of Mentha piperita under varying conditions of temperature and the leaf-by-leaf...

  • The biosynthesis of terpenes in Pelargonium graveolens

    Creator:
    Allison, Robert David
    Abstract:
    Pelargonium graveolens Ait., rose geranium, contains several oxygenated monoterpenes, most of which are related to each other structurally. In this work, the metabolism and interconversions of these terpenes was investigated. A chromatographic analysis of geranium oil was performed initially for the purposes of identifying the terpenes and determining which chromatographic...

  • Effects of selected minor alloying additions on the structure deformation characteristics of beryllium

    Creator:
    Dooley, George Joseph, III
    Abstract:
    Solid solution alloying was employed in an attempt to produce some relatively ductile form of beryllium. If the c/a ratio could be significantly altered, it was felt new or different slip systems could be activated. The following elements were selected on the basis of atomic size, melting point, crystal structure...

  • Low temperature deformation characteristics of high purity zirconium single crystals

    Creator:
    Goodrich, David George
    Abstract:
    High purity single crystals of zirconium were produced and mechanically strained in the temperature range from 4.2°K to 293°K. The crystals were produced by thermal treatment with a specially constructed electron beam zone refiner which provided the abrupt temperature gradient necessary for crystal growth. Specimens were electrolytically machined to have...

  • Indentation hardness of Douglas fir and Western hemlock lumber related to density

    Creator:
    Corder, Stanley E.
    Abstract:
    Indentation hardness tests were made on sections of 211 pieces of Douglas fir and 208 pieces of Western hemlock at a moisture content of about 11 percent. Specific gravity and visual-density evaluations were also determined. Correlation coefficients for linear regression of density, as measured by specific gravity, on average standard...
