  • Enzymatic versus nonenzymatic denitrification

    Creator:
    Bulla, Lee A.
    Abstract:
    Denitrification is classically defined as the microbial reduction of nitrate and nitrite with the liberation of molecular nitrogen and, in some instances, nitrous oxide. The sequence of reactions in which nitrogen is evolved as an end-product is essentially a respiratory mechanism in which nitrate and/or nitrite replaces molecular oxygen. The...

  • Thermal ecology of the garter snakes Thamnophis sirtalis concinnus (Hallowell) and Thamnophis ordinoides (Baird & Girard)

    Creator:
    Stewart, Glenn R.
    Abstract:
    In recent years, studies dealing with temperature regulation, temperature sensitivity, and physiological responses to temperature in lizards and other reptiles have increased tremendously. It is notable that snakes have been largely ignored in such studies. This no doubt is due to their less direct relationship to ancestral endotherms. However, problems...

  • The decay of ⁶¹Cu and ⁵⁹Cu--energy levels of ⁶¹Ni and ⁵⁹Ni

    Creator:
    Walker, Donald Arthur
    Abstract:
    The decay of ⁶¹Cu and ⁵⁹Cu produced by (d, n) reactions on natural nickel has been investigated. Gamma-ray energies and relative intensities were measured with a high resolution Ge(Li) spectrometer. The gamma-gamma coincidence spectrum of ⁶¹Cu was studied with a Ge(Li)-NaI(T1) system. From these data decay schemes of ⁶¹Cu and...

  • Spectral time-resolution of light from microwave discharges in helium

    Creator:
    Tynes, Arthur Richard
    Abstract:
    Temporal variations in individual spectrum lines emitted by a microwave discharge in pure helium are investigated: The discharge is produced in a quartz tube located inside of a section of waveguide which carries pulsed 3 centimeter microwaves. The helium used is purified by a three-fold process consisting of treatment with...
