  • Identification of some soluble esterases of the carrot (Daucus carota I.)

    Creator:
    Carino, Lourminia Almeda
    Abstract:
    Substrate and inhibitor specificities have been used to classify esterases. The purpose of this work was to determine the substrate and inhibitor specificities of the esterases in an aquous extract of lyophilyzed carrots. Esterase activity was determined manometrically at 37°C. The optimum pH of the carrot esterases with several substrates...

  • Identification of some esterases of the green bean (Phaseolus vulgaris L.)

    Creator:
    Putnam, Teryl Beebe
    Abstract:
    This investigation was conducted to differentiate the esterases in a water extract of freeze-dried green beans on the basis of inhibitor and substrate specificities. An attempt was made to classify these esterases according to the criteria used for animal esterases. Activity of the esterases was measured manometrically using the Gilson...

  • Effect of cadmium on ceruloplasmin levels in the rat

    Creator:
    Robinson, Alfred Vern
    Abstract:
    Injection of a 2.0 mg Cd ²⁺ /kg B.W. (I.P. as CdC1 ₂ in .05 M NaAc, pH = 6.9-7.2, .15 M or p = .15 with NaCl) resulted in a decrease in ceruloplasmin (EC 1.12.3) p-phenylenediamine oxidase activity within one hour of injection. Maximal decrease (40%) occurred within six...

  • Characterization of Stormwater Runoff from a County Maintenance Facility and Evaluation of Temporal Performance of Bioswale in Its Treatment

    Creator:
    Gyawali, Kshitiz
    Abstract:
    In the last few decades, a lot of studies have been conducted to study about the quality of stormwater runoff from various sites and conditions. Highways, residential areas, and commercial sites are the focus of most of these studies while limited studies have done examination of stormwater from Maintenance and...

  • Accumulation of dietary polychlorinated biphenyl by rainbow trout (Salmo gairdneri)

    Creator:
    Lieb, Andrew James
    Abstract:
    This study was conducted to investigate the accumulation of dietary polychlorinated biphenyls (PCB's) by a Mt. Shasta strain of rainbow trout (Salmo gairdneri). A commercial mixture of PCB's (Aroclor 1254) was added to the diet at a level of 15 ppm on a dry weight basis. Accumulation of PCB's was...

  • Functional profiles of soil microbial communities in second-growth Douglas-fir forests of the Pacific Northwest

    Creator:
    McGinnis, Megan L.
    Abstract:
    Forests are one of the largest repositories of terrestrial C. Understanding factors that drive organic matter transformations and nutrient efflux from these systems is therefore highly important. Temperate forests are of particular significance due to the large fraction of C that is stored below ground in the soil. Characterizing nutrient...

  • Classical chaotic scatting from symmetric four hill potentials

    Creator:
    Bauman, Jordan Michael
    Abstract:
    Classical chaotic scattering experiments were performed on ten different four hill potentials, unique under x-axis reflection, given by: V(x,y) = x²y²e⁻⁽ˣ² ⁺ ʸ²⁾ σᵢ where σᵢ was ±1 depending upon quadrant. Our work was based on a paper (9) that only studied the case where σᵢ =1 in all quadrants....

  • Ferroelectric thin film development

    Creator:
    Harman, Taran V.
    Abstract:
    The long-term goal of the research project initiated with this thesis is the development of lead-free, fully-transparent ferroelectric devices, such as ferroelectric capacitors or ferroelectric-gate field-effect transistors. Ferroelectric materials exhibit spontaneous polarization with the application of an external electric field, which is persistent upon removal of the applied field, and...

    Abstract:
    The Department of Nuclear Engineering at Oregon State University has performed a series of confirmatory tests for the United States Nuclear Regulatory Commission (USNRC). These tests have been conducted in the Advanced Plant Experiment (APEX) Facility which is a one quarter height scaled simulation of the Westinghouse Advanced Passive 600...

    Creator:
    Field, Marshall B.
    Abstract:
    Electrical resistivity and thermoelectric power measurements have been made over the temperature range of 450° to 600°C on n-type liquid thalliurn-tellurium solutions. Liquids with compositions from 61.5 to 72.0 atomic percent thallium were studied. In addition, alloys of some of the three component thallium-teIlurium solutions containing small amounts of silver,...
