  • Pillaging Bloodwood: An Exploratory Examination of Illegal Deforestation in Guinea-Bissau Through Forest Disturbance Algorithms and Unsupervised Clustering Techniques

    Creator:
    Walters, Alexander E.
    Abstract:
    Environmental crime around the world, such as trafficking in illegal timber, is directly related to political instability. Traffickers exploit weak, fragile, and chaotic political circumstances to illegally extract high-value commodities, challenging the extent to which conservation goals are achievable in resource rich developing countries. Rosewood is the largest traded endangered...

  • Verifying safe use of a thinner aluminum scattering chamber for fission physics

    Creator:
    Porter, Eben, Jr.
    Abstract:
    This thesis describes calculations done to determine the radiation hazard of the current Prompt Gamma Neutron Activation Analysis (PGNAA) scattering chamber at the Oregon State TRIGA Reactor (OSTR) and compare it to the amount that would be given off by a new thin-walled chamber design. These calculations were completed with...

  • Is Resistance Futile: Examining Fitness Costs Associated with QoI Resistance in E. necator

    Creator:
    Newbold, Chelsea L.
    Abstract:
    Quinone outside Inhibitor (QOI) fungicides are one of the most widely used fungicide classes (FRAC 11) in the world. This popularity is the result of their ability to effectively manage a wide array of economically important pathogen species on a broad range of crops. While having mostly preventative activity, some...

  • A second look at Alexander Pope and Newtonian science

    Creator:
    Reid, Tim S.
    Abstract:
    "This Long Disease, My Life": Alexander Pope and the Sciences by Marjorie Nicolson and G.S. Rousseau has been the standard work on Alexander Pope and Newtonian science ever since it was published in 1968. Literary scholars and biographers continue to be swayed by its influence. Unfortunately, the work they so...

  • Mitigation of Microbiological Water Quality by Last Irrigation-to-Harvest Intervals

    Creator:
    Emch, Alexander W.
    Abstract:
    Foodborne outbreaks involving fresh produce have been on the rise since the late 1990's. Pathogens such as Salmonella spp. and Escherichia coli are prevalent in agricultural environments and commonly travel between farms via irrigation water. The Food Safety Modernization Act (FSMA) has placed an increased emphasis on microbiological standards of...

  • Spherical mirror resonators and optical mode selection

    Creator:
    Adrion, Robert Foisy
    Abstract:
    This is a review paper based on recent literature in the areas of spherical mirror resonators and optical mode selection. The Fabry-Perot interferometer with spherical mirrors has been widely used as a laser resonator. The modes of oscillation, diffraction losses and resonance condition are determined for the confocal resonator, i.e....

  • Gas ratio and pressure effects on the 6328 A⁰ transition of the helium-neon gas laser

    Creator:
    Freytag, Edwin Karl
    Abstract:
    This is a review paper of current literature in the area of pressure effects on gaseous lasers. This thesis discusses the mechanisms which relate the relative power output of the 6328 A[superscript ⁰] neon transition to total and partial pressure variations of the helium-neon gaseous laser. The operation of the...

  • Microstrips on gold-doped silicon substrates

    Creator:
    Lai, Cheng-wen
    Abstract:
    The power dissipation of microstrip transmission-line on gold-doped silicon substrates was investigated. The gold-doping was applied to a regular n-type silicon substrate with resistivity of 5 to 10 ohm-cm. Insertion-loss tests were employed to measure the power dissipation of the microstrips. Power dissipation somewhat less than that for intrinsic silicon...

  • Coastal ocean variability inferred from high resolution models : two case studies

    Creator:
    Mauch, Matthew L.
    Abstract:
    In this thesis, high resolution ocean models are used to evaluate and forecast coastal ocean variability in two different applications. In the first study, the 2-km resolution ocean circulation model for the Eastern Bering Sea is utilized to understand whether slope-interior exchange along the path of the Aleutian North Slope...

  • Analysis and synthesis of exponentially tapered, nonuniform transmission line impedance transformers

    Creator:
    David, Frank Kolar
    Abstract:
    The exponentially tapered, nonuniform transmission' line, applied as an impedance transformer, is analyzed and modified. The analysis develops an expression for the input reflection coefficient that has the magnitude and phase as distinct functions. This allows ease in comparing the approximate and exact solutions and in developing the S-parameters for...
