  • Micromechanics of heterogeneous materials under compressive loading

    Creator:
    Laird, George
    Abstract:
    In mining and mineral processing, compressive loading is often encountered during the comminution of ore bearing minerals and in the wear resistant materials used in the comminution circuit. A common thread joining many of the materials that are primarily used under compressive loading is the presence of a high modulus...

  • Stability analysis of dynamic heat transfer

    Creator:
    Luo, Shyr Tung
    Abstract:
    The stability analysis for a heated tube system is an important safety feature of a nuclear power plant. Although the system theory is well established for linear systems described by ordinary differential equations, there is still a shortage of theory dealing with a distributed system, which is described by partial...

  • Nitrogen management and variety selection for dryland production of hard red winter wheat in northeastern Oregon

    Creator:
    Jepsen, Daniel R.
    Abstract:
    Proper nitrogen (N) management and variety selection are important for profitable hard red winter (HRW) wheat production in the dryland growing regions of northeastern Oregon. In these dryland systems, N management for grain yield and grain protein concentration (GPC) is challenging due to climatic and year-to-year variation in production environments....

  • Winterfat seed viability and dormant season livestock grazing

    Creator:
    Leary, Ryan
    Abstract:
    Krascheninnikovia lanata (winterfat) is a valuable forage species with an average of 10% crude protein during winter when there are few nutritious options for livestock and wildlife. However, excessive grazing throughout the west has negatively impacted survival of winterfat stands. We hypothesized that four years rest from dormant season livestock...

  • Natural Convection Heat Transfer and Boundary Layer Transition for Vertical Heated Cylinders

    Creator:
    Goodrich, Sam S.
    Abstract:
    In recent years, the global nuclear industry has placed a greater emphasis on passively safe reactor designs. In particular, much attention and design work has been applied to engineered systems for passive cooling of nuclear fuel, whether it be loaded in a core or stored in spent fuel pools. The...

  • Effect of site potential, season and plant part on the quality and yield of cereal aftermath

    Creator:
    Mee, Catherine
    Abstract:
    The objectives of this study were to evaluate the effects of site potential, season and plant part on percent crude protein, percent digestibility of dry matter and yield of cereal residues. Three cereal types, club wheat (Triticum aestivum) tall, bearded wheat (T. aestivum), and barley Hordeum vulgare) were examined. Stress...

  • A chopper-stablized CMOS operational amplifier

    Creator:
    Ann, Seung-Han
    Abstract:
    The chopper-stabilized operational amplifier has good low frequency noise properties. Unfortunately a simple technique for simulation of the chopper-stabilized operational amplifier has not been available. This thesis describes the implementation of a differential amplifier using chopper stabilization and its circuit modeling for the SPICE simulation. This circuit has been designed...

  • Mapping quantitative trait loci underlying genome-wide recombination rate and mating system differences in meadowfoam

    Creator:
    Kishore, Venkata Krishna
    Abstract:
    Meadowfoam (Limnanthes alba Bentham; Order: Brassicales; Family: Limnanthaceae) is a self-compatible, predominantly allogamous, insect pollinated species. Meadowfoam oil is a source of novel unsaturated very-long-chain (VLC) seed oils (C₂₀ and C₂₂) with low concentrations of saturated fatty acids (typically less than 2%) and outstanding oxidative stability. Here we report the...

  • Wheat flour arabinoxylans in soft wheat end-use quality

    Creator:
    Asawaprecha, Sunida
    Abstract:
    Little is known about the effects of arabinoxylans (AX) on noodle quality. The aim of this study was to observe interrelationships between wheat flour AX, SRC tests, and noodle quality attributes, and to investigate the use of SRCs to predict cookie diameter. Cookie diameter is the most common index of...
