  • Lead(II) Extraction with Electrospun Spiropyran Functionalized PMMA Nanofibers

    Creator:
    Fuchs, Brian K.
    Abstract:
    A system to reversibly extract Pb²⁺ ions from aqueous solutions using spiropyran functionalized nanofibers was proposed. Spiropyrans are photochromic compounds which undergo a conformational change that alters their physical properties and makes Pb²⁺ binding possible upon irradiation with UV light (365 nm). Irradiation with green light (525 nm) reverses this...

  • 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...

  • Activation of Co-stimulatory Molecule OX40 Increases Memory T-cell Function and Cytokine Production in Uveitis

    Creator:
    Hall, Mark
    Abstract:
    Uveitis is a serious ophthalmological disorder characterized by intraocular infiltration of inflammatory cells. In most cases, uveitis is derived from the adaptive immune response. More specifically, CD4+ T lymphocytes play an important role in the pathogenesis of uveitis by recognizing uveitogenic antigen and orchestrating the immune response. While it is...

  • Luteinizing hormone receptor-mediated cell proliferation in canine T-cell lymphoma cells

    Creator:
    Flint, Camryn
    Abstract:
    Luteinizing hormone (LH) is secreted in low-amplitude pulses in sexually intact dogs to stimulate synthesis of estrogen and testosterone in females and males, respectively. LH is mainly considered a reproductive hormone, but LH receptors (LHR) have been identified in non-reproductive tissues, including in canine lymphoma and isolated canine T-cell lymphoma...

  • Characterizing the Interaction between BCL11B and TCF-1 transcription factors in the control of the BCL-xL gene

    Creator:
    Nagra, Alamjit K.
    Abstract:
    Immature T cells, known as thymocytes, undergo development through successive stages in the thymus and the periphery to become functional mature T cells. These stages are regulated by sequence specific transcription factors (SSTFs). Two such SSTFs, BCL11B and TCF-1, are both known master regulators of thymopoiesis, which is also known...

  • Acclimation to Nutrient Limitation in Microalgae

    Creator:
    Moua, Bethany K.
    Abstract:
    Microalgae play an important role in the marine ecosystem. They are primary producers and form the base of the aquatic food web. The effects and changes that occur to microalgae are expected to have influences on the higher tropic levels. One major factor that influences growth of microalgae is the...

  • Mothers’ anxiety induced by COVID-19 pandemic and their children’s executive function outcome

    Creator:
    Nichols, Austin T.
    Abstract:
    The COVID-19 pandemic significantly impacted family dynamics, specifically with mothers experiencing unique stressors and challenges. This study explored the association between mothers' anxiety induced by the COVID-19 pandemic and their children’s executive function outcome during preschool. A quantitative approach was used with a sample of 219 families in Oregon, utilizing...

  • Differences in expression of COVID-19 related inflammatory genes in non-human primates with varying alcohol consumption

    Creator:
    Co, Amber
    Abstract:
    Severe cases of COVID-19 have been associated with cytokine storms, leading to widespread inflammation, tissue damage, and organ failure. Pro-inflammatory cytokines have also been shown to play a role in liver diseases, including alcoholic liver disease. To investigate alcohol consumption as a risk factor for SARS-CoV-2 infections and COVID-19 severity,...

  • Photoactuated Droplet Microfluidics

    Creator:
    Frederick, Ryan T.
    Abstract:
    A system of Photoactuated Droplet Microfluidics (PDM), in which a droplet of fluid is moved by way of the manipulation of the wettability of a spiropyran functionalized surface via irradiation with ultraviolet and visible light, was proposed. The photochromic behaviors of several species of spiropyran were studied and a procedure...

  • Creating and Assessing Cozmo Behaviors for Expressing Emotion

    Chan, Lilian C.
    Abstract:
    As human-robot interaction becomes more commonplace, roboticists should understand how robot behaviors are perceived by people to avoid misunderstandings. In our lab, we are exploring the use of a Cozmo as an interactive, break-taking aid in workplace settings. Before our interactive aid can be released into the wild, we must...
