PERT-IV, a two-dimensional perturbation theory code for fast reactors

Creator:: Hardie, Ralph Wayne
Abstract:: A two-dimensional perturbation theory computer code, PERT-IV, has been developed that will calculate reactivity coefficients, the delayed neutron fraction, and the neutron generation time. The program uses the output flux and adjoint flux from either a diffusion theory or transport theory program. A discussion and derivation of the perturbation equation...

A method for calculation of group-averaged resonance parameters

Creator:: Nail, James Harold
Abstract:: A method of treating resonance captures for few energy group calculations is developed using the Narrow Resonance-Infinite Absorber approximation to the resonance integral. The application of this method is not restricted to this approximation, however, as other approximations to the resonance integral could also be used. The approach presented defines...

Energy models for computing fast reactor parameters

Creator:: Lorenzini, Paul Gilbert
Abstract:: Because of the complicated form of the diffusion equation, approximations are necessary to treat the energy dependence for practical problems. The standard model is the few group approximation. A second approximate form, the overlapping group or modal method, is examined and more fully developed in this work to provide an...

Electron microscopic observation of alpha particle tracks in cellulose nitrate

Creator:: Fish, Robert Lawrence
Abstract:: The work in this thesis involves the development of specimen preparation techniques for the observation with an electron microscope of alpha particle tracks in cellulose nitrate plastic. Both direct observation using thin films and replica production techniques were investigated. Direct observation of the alpha tracks was accomplished by cutting thin...

Growth and replacement patterns occuring among selected dominant species associated with plant succession on Douglas fir clear-cuts

Creator:: Robinson, Myles Canby
Abstract:: Growth and replacement patterns of four successionally important species occurring on Douglas fir clear-cuts were investigated from September 1964 to June 1967. The study was carried out on the Marys Peak watershed located near Corvallis, Oregon. Species used in the study include Holcus lanatus, Senecio jacobaea, Lotus crassifolius var. subglaber,...

Neutron-induced autoradiography of lithiasilica microspecimens : Specimen preparation and preliminary alpha tracking

Creator:: Wood, F. W. (Floyd William), 1926-
Abstract:: Lithia-silica compositions between lithium disilicate and pure silica were explored theoretically and experimentally, with special emphasis on structural miscibility. Diffusion couples of vitreous materials were prepared and annealed. Best success in preparation was achieved by using electron-bombardment heating in vacuum to melt the less refractory glass and let it solidify...

Studies on the inhibition of bovine plasma amine oxidase by hydrazines

Creator:: Hucko-Haas, Jacqueline Elizabeth
Abstract:: Several aspects of the potent inhibition of bovine plasma amine oxidase (PAO) by hydrazines were investigated by kinetic and preparative means. The inhibition was classified as pseudo-irreversible by the method of Ackerman and Potter (Proc. Soc. Exptl. Biol. Med. 72, 1 (1949), and was found to exhibit Zone B kinetic...

Distribution of understory species in relation to maximum and minimum tree influence in the montane forest of the Central Oregon Cascades

Creator:: Robinson, Andrew Frederick, Jr.
Abstract:: Twenty sites of uniform topography and soil were select ed in the montane forest found on the East flank of the Central Oregon Cascades. These sites were located along a vegetational gradient composed of five plant communities: Abies/Pachistima, Pinus/Ceanothus, Pinus Arctostaphylos-Purshia, Pinus/Purshia/Festuca, and Juniperus Festuca. An attempt was made to...
