  • Analysis of the D. C. electric field for a pipeline in a three layered earth

    Creator:
    Brandenstein, Albert Edward
    Abstract:
    This paper develops an equation, from an heuristic set of assumptions, which describes the axial current, leakage current, resultant electric field, and resultant earth potential occurring when a pipeline buried within a resistive earth is subjected to a distributed, primary, axial, electrostatic field produced from a high-voltage, direct-current (HVDC) power...

  • Sorption of NH₃ in a dry system in relation to the chemical properties of clays and soils

    Creator:
    James, D. W. (David W.), 1929-
    Abstract:
    The physico-chemical reactions of ammonia in soils and clays have many practical and theoretical implications. On the one hand, large quantities of anhydrous ammonia are used annually in agriculture for fertilizer; the dry gas is applied directly to the soil by simply injecting it below the ground surface. On the...

  • Kinetic studies of the oxygen requirement of some amine oxidases

    Creator:
    Swindell, Robert Malcolm
    Abstract:
    Some kinetics of the oxygen requirement of amine oxidases have been investigated using bovine plasma monoamine oxidase (PAO) and pea seedling diamine oxidase (DAO). A system is described for studying enzyme reactions under controlled oxygen tension and in an O₂-free N₂ atmosphere. O₂ Km values were determined at two different...

  • Cloudiness in the Willamette Valley of Oregon

    Creator:
    Heinsohn, Frank Peter
    Abstract:
    Temporal and spatial patterns of daytime cloudiness in the Willamette Valley of Oregon were studied by utilizing monthly and daily sky cover data published by the U. S. Weather Bureau for the Portland, Salem, and Eugene stations. The 15-year period, 1949 through 1963, was selected as the maximum reliable period...

  • Gas chromatographic identification of chlorinated insecticides based on their U.V. degradation

    Creator:
    Banks, K. A. and Bills, D. D.
    Abstract:
    Certain chlorinated insecticides can be identified by electron capture gas­-liquid chromatographic (EC-GLC) analysis of the prepared sample before and after treatment with ultraviolet irradiation, Upon U.V. treatment, characteristic degrada­tion products arise from the insecticides investigated. Comparison of the degradation pattern obtained by EC-GLC of unknown and authentic insecticides provides an...

  • A study of the deterioration of X-ray fluoroscopic screens

    Creator:
    Properzio, William Stuart, 1940-
    Abstract:
    From the time when fluoroscopic screens were first used there have been scattered references to reduction in their light output due to age, use, etc. References are scarce and usually devoid of quantitative data. A long-range program has been set up in an effort to arrive at some meaningful information....

  • Studies on control of diacetyl off-flavor in beer

    Creator:
    Tolls, Terry Norman
    Abstract:
    Sporadic outbreaks of diacetyl off-flavor in beer are a serious economic problem to the brewing industry. Studies were carried out in an attempt to improve the understanding of the problem and to experiment with new ways of controlling this defect. The Owades and Jakovac method of diacetyl determination as modified...

  • Some aspects of the mechanism of action of iodophor and other germicides on microorganisms

    Creator:
    Shikashio, Tommy Kiyoshi
    Abstract:
    The concentrations of iodophor necessary to reduce the activity of several metabolic enzyme systems 50 percent was used as the basic approach in attempts to elucidate the mechanism of germicidal action of iodine. For comparisons, a chlorine-releasing germicide (Trichlorocide) and a quaternary ammonium compound were also tested. It was found...

  • Dynamic measurement of Timoshenko beam shear coefficient

    Creator:
    Nelson, Daniel Loren
    Abstract:
    The Timoshenko beam theory, as an engineering alternative to the elementary and exact theories, introduces a factor, k', called the shear coefficient which has been given various interpretations and values. It is the objective of this study to experimentally evaluate k' for a brass bar of rectangular cross-section. Analytical results...
