  • Regulation of the Pantoea agglomerans type III secretion system by plant-exuded sugars

    Creator:
    Bacher, Daniel
    Abstract:
    Pantoea agglomerans pathovar betae (Pab) is a bacterium that causes galls on the roots of beet plants, resulting in reduced marketability of beet roots and crop loss. Pab uses a type III secretion system (T3SS) to infect and cause galls on beets. The T3SS is a molecular syringe-like structure that...

  • Selective Laser Melting of H13 Tool Steel for Rapid Tooling

    Creator:
    Katancik, Michael
    Abstract:
    The current knowledge on the microstructural evolutions and mechanical properties of selective laser melting (SLM) produced H13 tool steel components is limited. This research is focused on optimization of SLM processing parameters for H13 tool steel and investigation of microstructure and mechanical properties of H13 tool steel components after SLM...

  • Modeling the Fusion Reaction in an Inertial Electrostatic Confinement Reactor with the Particle-in-Cell Method

    Creator:
    van de Lindt, Jacob
    Abstract:
    Nuclear fusion has the potential to meet the energy needs of our civilization for centuries to come and does not produce harmful greenhouse gasses or produce long-lasting radioactive waste. A fusion reaction can be readily demonstrated in a confinement scheme known as inertial electrostatic confinement (IEC) fusion. In this work,...

  • Examination of the Impact of One-Dimensional Crustal Structures on Cascadia Subduction Zone Earthquake Locations

    Creator:
    Meyer, McKenzie S.
    Abstract:
    Multiple earthquake events have been recorded off the coast of Oregon, yet their locations have great uncertainty. The largest source of uncertainty is the simple models of the crust that are used to interpret seismic recordings. Because the relationship between earthquake locations and crust are diagnostic of tectonic activity, it...

  • Correlation Between Fine Particulate Matter and Traffic Type and Density in Curitiba, Brazil

    Creator:
    Fantoni, Costanza
    Abstract:
    Traffic exhaust is an important source of air pollution. This exposure assessment study examined traffic related air pollution in Curitiba, Brazil, and is particularly relevant due to 75% of the population using diesel public transportation. Traffic density was tabulated, and vehicle-type was distinguished based on their fuel type (diesel or...

  • A Vector–Host Model for Coinfection by Barley/Cereal Yellow Dwarf Viruses

    Creator:
    Leung, Margaret-Rose W.
    Abstract:
    Barley and cereal yellow dwarf viruses (B/CYDV) are a suite of aphid-vectored pathogens that affect diverse host communities, including economically important crops. Coinfection of a single host by multiple strains of B/CYDV can result in elevated virulence, incidence, and transmission rates. We develop a model for a single host, two...

  • Into the Garden: Environmental Education and Resources for K-5

    Creator:
    Smith, Amira R.
    Abstract:
    This thesis aims to address barriers that K-5 educators face when implementing environmental education in classrooms. An in-depth study of the history of environmental education in the United States identifies primary barriers and issues. Focusing specifically on garden education programs, six lesson plans for K-5 were created to address the...

  • Melting Stage Analysis for Indirect Freeze Desalination

    Creator:
    Pratt, Mason G.
    Abstract:
    To investigate the melting stage of indirect freeze desalination three numerical models were developed. A zeroth, first, and second order analyses modeled the melting of ice around the outside of a pipe as a function of time. The zeroth order analysis assumes the system to be steady state. The first...

  • Direct Numerical Simulation of Anisotropic Particles in Turbulent Flow

    Creator:
    Roberts, Kai
    Abstract:
    Turbulent flows with suspended, non-spherical particles are common in many natural and industrial processes. To identify the effects of anisotropic geometry on particle dynamics, a one-way coupled Lagrangian direct numerical simulation solver was written, verified, and used to collect data on particles simulated in multiple flows. This thesis explains the...

    Meeuwsen, Rachel M.
    Abstract:
    High purity isopropyl alcohol (IPA) is utilized in silicon wafer manufacturing in cleaning and drying processes. With the ever-decreasing die size, there is an increased need for even higher purity chemicals. This process was designed to further purify a 250,000 lbs/month stream high purity isopropyl alcohol stream for use in...
