  • 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...

  • 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,...

  • 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...

  • Quantification of fibrinogen adsorption to nisin-loaded polyethylene oxide layers

    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,...

  • 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...

  • 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...

  • Assessing Annelid Habitat Suitability in the Lower Klamath River Basin

    Creator:
    Corrigan, Rory
    Abstract:
    This study assessed suitability of annelid habitats under current baseflow conditions and evaluated the mobility of suitable annelid substrates under a 2-year peak flushing flow. Outputs from a 2020 Bureau of Reclamation SRH-2D model were combined with field measurements of annelid presence/absence and habitat variables including depth, velocity and d50,...

  • The Advantages of Creating a Board of Directors in a Family Business

    Creator:
    Vásquez Solórzano, Juan Gabriel
    Abstract:
    This paper seeks to provide a practical answer to the following question: why create a board of directors in a family business? To achieve this, it summarizes the existing research published in the field of family business governance that directly addresses the beneficial role of the board of directors in...

  • Effects of ocean acidification on growth rate, calcified tissue, and behavior of the juvenile ochre sea star, Pisaster ochraceus

    Creator:
    Britsch, Melissa L.
    Abstract:
    Anthropogenically-induced increases in the acidity of the ocean have the potential to seriously harm marine calcifying organisms by decreasing the availability of carbonate (CO32−) used to make shells. I tested the effects of lowered pH on juvenile Pisaster ochraceus, an intertidal sea star and keystone predator in the eastern Pacific...
