  • A genetic study of the red-band trout (Salmo sp.)

    Creator:
    Wilmot, Richard L.
    Abstract:
    A group of trout that reside in streams of the desiccating lake basins of southeastern Oregon differ markedly from other known Salmo. Known commonly as the red-band trout, this fish was subjected to chromosome analysis for comparison with other species of western North American Salmo. The karyotype of the red-banded...

  • The effect of monensin on efficiency and production of a brood cow herd

    Creator:
    ZoBell, Dale Richard
    Abstract:
    Ninety-six mature pregnant Hereford cows were allotted to three replications with four treatments. Pregnancy was determined by rectal palpation prior to the initiation of the study. The cows were artificially inseminated the previous spring, beginning the end of May, over a period of 42 days to a single Angus sire....

  • Design considerations for a miniature atmospheric engine with a magnet-actuated autonomously-reciprocating in-cylinder regenerator for portable power production

    Creator:
    Yarger, David J.
    Abstract:
    Driven by the need for high energy-density power sources, demand has stimulated the development of small-scale engines. A small-scale engine with a fuel supply could replace batteries and utilize higher energy-density liquid hydrocarbon fuels; such an advance could deliver a new age of portable devices. Currently, operable small-scale engines exist;...

  • Physiology of senescence of the shoot apex in Pisum sativum L.

    Creator:
    Ecklund, Paul Richard, 1941-
    Abstract:
    Shoot apex senescence is defined as the collective progressive and deteriorative processes which ultimately terminate the functional life of the shoot apex. Senescence of shoot apices of Pisum sativum L. 'Alaska' as measured by cessation of stem elongation was delayed by removal of flowers and by treatment with gibberellin A₃...

  • Phylogenetics and genomic patterns of speciation in Pinus with an empahsis on subgenus Strobus

    Creator:
    Syring, John V.
    Abstract:
    Data from nuclear ribosomal internal transcribed spacer regions (nrITS) and chloroplast DNA (cpDNA) have failed to resolve phylogenetic relationships in Pinus. To provide greater interspecific resolution, five low-copy nuclear genes were developed from mapped conifer anchor loci. Four genes were sequenced from species representing all Pinus subsections. Individual loci do...

  • Multi-bit delta-sigma switched-capacitor DACs employing element-mismatch-shaping

    Creator:
    Lin, Haiqing
    Abstract:
    Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital and digital-to-analog converters (ADCs and DACs). Most delta-sigma modulators in production today employ single-bit quantization because a 1-bit DAC is inherently linear, whereas a multi-bit DAC is not. Were it not for this drawback, the use of multi-bit...

  • Lowpass and bandpass current-mode delta-sigma DACs employing mismatch-shaping

    Creator:
    Shui, Tao, 1969-
    Abstract:
    Delta-sigma modulators are currently a very popular technique for making high-resolution analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). These oversampled data converters have several advantages over conventional Nyquist-rate converters, including an insensitivity to many analog component imperfections, a simpler antialiasing filter and reduced accuracy requirements in the sample and hold....

  • The effects of locus of control and instructional method on self-efficacy with computers

    Creator:
    Whyte, Catherine K.
    Abstract:
    The purpose of this experiment was to investigate the interactive effects of locus of control and instructional method on perceived self-efficacy with computers. The two instructional methods in this experiment were intended to represent variations in the amount of control over the lesson that students would have, the amount of...
