  • Significance of High-Pressure-Torsion Processing on an Aluminum-Lithium Aerospace Alloy

    Creator:
    Keller, Marina
    Abstract:
    Aluminum alloys are popular in aerospace and automotive industries because of their relatively high strength-to-weight ratio. The study of enhancing aluminum’s mechanical properties through grain refinement is especially important. One such technique is High-Pressure Torsion processing (HPT), which leads to significant grain size refinement and enhances mechanical properties like ductility...

  • Application of Spectroscopic Techniques for In-Situ Oxygen Monitoring in Liquid Sodium

    Creator:
    Walton, Seth L.
    Abstract:
    In liquid sodium environments like those proposed for next-generation sodium fast reactors (SFRs), the presence of impurities in the sodium, particularly chemical species containing oxygen, can lead to increased corrosion on sodium-wetted components. It is important to monitor oxygen concentration in the sodium melt, but temperatures of 500 ℃ and...

  • Calpain 2 Cleavage of Akt in Glioblastoma Multiforme

    Creator:
    Zhang, Justin
    Abstract:
    Glioblastoma is a malignant brain tumor that has extremely poor prognoses with a 5 year survival rate of less than 5%. The low survival rates of glioblastoma patients is attributed to glioblastoma cells being extremely resistant to radiotherapy and chemotherapy as well as being very invasive. We previously identified calpain...

  • Real-time Speech Workload Estimation

    Creator:
    Fortune, Julian D.
    Abstract:
    Demanding task environments (e.g., supervising a remotely piloted aircraft) require performing tasks quickly and accurately; however, periods of low and high operator workload can decrease task performance. Intelligent modulation of the system’s demands and interaction modality in response to changes in operator workload state may increase performance by avoiding undesirable...

  • Surface Modifications for Greater Cycle Life and Energy Density in Lithium-Ion Batteries

    Creator:
    Holstun, Tucker M.
    Abstract:
    Significant challenges remain before lithium-ion batteries can support the decarbonization of the transportation and power sectors required to avert catastrophic climate change. The energy density of these batteries must be increased, while decreasing the price, and maintaining or increasing their lifespan. To improve the practical energy density of existing materials,...

  • Inhibition of α-Amylase and α-Glucosidase by Bioflavonoids

    Creator:
    Griffith, Anneke M. (Tucker)
    Abstract:
    Various flavonoid-rich plant extracts have shown efficacy in the treatment of diabetes. Although it is often assumed that dietary flavonoids exert biological antioxidant effects, it is possible that the observed effects work in carbohydrate metabolism. In this study we evaluated the effect of catechins and catechin containing extracts on α-amylase...

  • Implementation of Distributed Localized Communications

    Creator:
    Snyder, Thomas
    Abstract:
    Artificial collectives are useful for accomplishing tasks that require teamwork from multiple simple robots. Multiple robot and collective testbeds have been developed, yet none stay committed to leverage the local interactions, group size, and imperfect information assumptions that strengthen biological collectives. A review of the collective and multiple robot literature,...

  • Environmental DNA reveals cryptic parasite species and gives insight into their fish hosts

    Creator:
    Phillips, Kyle
    Abstract:
    Ceratonova shasta is a myxozoan fish parasite that impacts hatchery and wild populations of salmon and trout in the Pacific Northwest. Levels of the parasite in river water can be effectively monitored through direct filtration of parasite spores from water, extraction of total "environmental DNA" (eDNA), then quantitative polymerase chain...

  • Evaluating the Impact of Beta-Lactam Allergy Labels on Patient Outcomes in Bone Marrow Transplant Patients

    Creator:
    Haxby, Benjamin M.
    Abstract:
    Background: Patients with a beta-lactam allergy noted in their medical record (i.e., allergy label) receive different antibiotics, even when an allergy is not truly present. Our objective was to evaluate allergy labels and their influence on patient outcomes among bone marrow transplant (BMT) recipients. Methods: We conducted a retrospective cohort...

    Creator:
    Auxier, Julie A.
    Abstract:
    Antimicrobial coatings used to reduce the risk of infection caused by tissue-contacting medical devices must address specific biocompatibility requirements including prevention of thrombosis and rise of bacterial resistance. An antimicrobial-loaded poly(ethylene-oxide) (PEO) coating has been tentatively shown to be non-fouling with sustained antimicrobial activity. However, the presence of the antimicrobial,...
