  • DNA Mismatch Repair-Dependent Suppression of Genotoxicity of Benzo[a]pyrene Diol Epoxide

    Creator:
    Kernan, Casey P.
    Abstract:
    DNA mismatch repair (MMR) plays an important role in preserving genomic stability and reducing cancer risk. Environmental exposures to polycyclic aromatic hydrocarbons (PAHs) are believed to contribute significantly to carcinogenesis. PAHs are found in food, air, water and soil and upon bioactivation can form diol epoxides which are electrophilic in...

  • Dielectric Properties of Perovskite Ceramics Based on BaTiO3 and Bi(Mg1/2Ti1/2)O3

    Creator:
    Sundahl, Christopher S.
    Abstract:
    The properties of (1-x)BaTiO3-xBi(Mg1/2Ti1/2)O3 (BT-BMT) ceramics were fabricated from reagent-grade ceramic powders by solid-state methods and investigated for solubility, relative permittivity, dielectric loss, polarization, and electromechanical strain. The solubility limit was found to be between x = 0.3 and 0.4. Ba-deficient samples were fabricated, corresponding to stable single-phase compositions; these...

  • Examination of Dielectric Properties of BaTiO3-SrTiO3 Based Systems

    Creator:
    Trobough, Nathaniel D.
    Abstract:
    This thesis examines the dielectric properties of two systems based on the perovskite materials barium titanate and strontium titanate. A solid solution was created starting with these base materials and then adding varying amounts of bismuth-zinc titanate and sodium niobate. These compositions were calcined and sintered at temperatures determined to...

  • Perspectives on a Community Forest : A Practice in Nature Writing

    Creator:
    Hadella, Lucia C.
    Abstract:
    The McDonald Forest is one of the Oregon State University Research Forests, owned by the College of Forestry and located approximately seven miles northwest of the heart of Corvallis. I took four hikes on the McDonald Forest at four major recreation destinations: Oak Creek, Dimple Hill, Lewisburg Saddle, and Peavy...

  • Empathy-Induced Distress: A Psychophysiological Approach

    Creator:
    Karabinas, Isabella M.
    Abstract:
    Empathy is considered a significant motivator of prosocial behavior. Increasing evidence suggests that feelings of personal distress associated with empathy may be stronger or weaker according to the form of perspective taking that an empathizer utilizes. The aim of the present study was to further quantify the stress consequences and...

  • Karmic Effects: How Aggressive Behavior Toward Important People Changes the Perception of Others

    Creator:
    Whitman, Frederick R.
    Abstract:
    Synthesizing perspectives from Bruner (1957), and the Mind Only School of Buddhism, the current study examined the effect of a persons’ own behavior on knowledge activation. Both social cognitive psychology and the Mind Only School posit that perception is based on previously learned knowledge. Knowledge is accumulated through an individual’s...

  • Mycobacterium tuberculosis Selective Adenosine Kinase Nucleoside Polymers for Inhalation Therapy

    Creator:
    Snow, Erika
    Abstract:
    Respiratory illnesses caused by both viral and bacterial infection are serious issues for global healthcare providers. With the emergence of new, drug-resistant forms of these diseases, innovative drugs and treatment therapies are needed. M tuberculosis is an infection that affects a large portion of the world’s population each year. Aerosol...

  • ⁴⁰Ar/³⁹Ar Ages and Trace Element Variations in Colombian Emeralds

    Creator:
    Svadlenak, Ellen
    Abstract:
    The Colombian emerald deposits are globally unique because they are hosted in hydrothermally altered black shales on either side of the Cordillera Oriental. We used electron microprobe analysis to study variations in trace element concentrations in transects across emeralds, and used the ⁴⁰Ar/³⁹Ar dating method to determine the age of...

  • Change in Hydraulic Conductivity of Expansive Soils

    Creator:
    Hesseltine, Johnathon
    Abstract:
    Swelling soils cause millions of dollars of damage to buildings every year in the Unites States alone. One essential piece to understanding these soils is to understand how water moves through them. Hydraulic conductivity is a measure of how easily water flows through a soil. Currently, the most common method...

  • Design and Manufacture of a Solar-Powered Snow Melter for Making Potable Water on Mt. Rainier.

    Creator:
    Hopple, Whitney K.
    Abstract:
    Every Spring and Summer, thousands of climbers attempt to summit Mt. Rainier. Many of them stop at Camp Muir, a base camp at 10,000 feet, where they can use restrooms, camp overnight, or refill water bottles before continuing their climb. Camp Muir currently uses a gas system to melt snow...
