  • Liquid entrainment at an upward oriented vertical branch line from a horizontal pipe

    Creator:
    Welter, Kent B.
    Abstract:
    Under simulated accident conditions, tees in the primary coolant loop of a Pressurized Water Reactor (PWR) can deviate from their original design purpose and become separators that effectively remove core heat sink capacity. This method of primary coolant removal is a phenomelogical subset of phase separation known as liquid entrainment,...

    Abstract:
    A literature review of current phase separation publications was conducted. Data sets were collected and compiled into a Two-Phase Flow Separation Database. Examination of this database indicating a need for further investigation into the liquid entertainment phenomena for smaller hot-leg to branch diameters and intermittent flow regimes. A detailed analysis...

    Abstract:
    The Lights Creek Stock is an 18 square kilometer copper-bearing granitoid intrusion within the Plumas Copper Belt in the northern California Sierra Nevada. Engels Mine, Superior Mine, and Moonlight Valley represent the main copper-mineralization in the Lights Creek district and small prospects include the Ruby Mine, and Moonlight Creek. The...

  • Analog integrated circuit design using GaAs C-HFETs

    Creator:
    Gupta, Rakhee
    Abstract:
    Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...

  • Seasonal relationships between dissolved nitrogen and landuse/landcover and soil drainage at multiple spatial scales in the Calapooia Watershed, Oregon

    Creator:
    Floyd, William C.
    Abstract:
    The Calapooia River, a major tributary of the Willamette River in western Oregon, is a watershed typical of many found in the Willamette Basin. Public and private forested lands occur in the steep Upper Zone of the watershed, mixed forest and agriculture lands are found in the Middle Zone, and...

  • Nitrogen 15 studies with nonleguminous nitrogen-fixing plants

    Creator:
    Webster, Stephen Russell
    Abstract:
    Snowbrush (Ceanothus velutinus), red alder (Alnus rubra), and bitterbrush (Purshia tridentata) are three important nitrogen- fixing nonleguminous species. They commonly grow in association with commercially important conifers in western United States and conceivably could be utilized to add nitrogen to forest ecosystems. Nitrogen 15 gas was used to study nitrogen...

  • Zinc-65 uptake by a bacterium isolated from Alder Slough, Columbia River Estuary

    Creator:
    Tonjes, Stephen Dodd
    Abstract:
    Bacteria were isolated from water at Alder Slough, Oregon. Of 15 isolates grown successfully in the medium employed, 100% showed measurable uptake of Zn-65. A growth curve was established for one isolate, a gram-negative rod designated AS-1. Increasing Zn-65 uptake was found generally to correspond with increasing growth of AS-1....

  • The effect of feeding tallow, urea and protected tallow on in vivo nutrient digestion in sheep

    Creator:
    Aseltine, Mark Stephen
    Abstract:
    Five sheep digestion trials with four animals per treatment and three treatments per trial were conducted to determine if feeding protected tallow and/or protein would alter the deleterious effects of feeding urea and tallow together. Apparent digestibility coefficients, nitrogen retention and biological values were calculated. An additional trial was also...

  • Nuclear design analysis of low-power (1-30 KWe) space nuclear reactor systems

    Creator:
    Gedeon, Stephen R.
    Abstract:
    Preliminary nuclear design studies have been completed on ten configurations of nuclear reactors for low power (1-30 kWe) space applications utilizing thermionic energy conversion. Additional design studies have been conducted on the TRICE multimegawatt in-core thermionic reactor configuration. In each of the cases, a reactor configuration has been determined which...
