  • Unmanned Aerial Vehicle Propulsion

    Creator:
    Brown, Sean
    Abstract:
    There is a growing US interest in UAVs for many applications ranging from agriculture to military. One area of improvement that can be realized in each category is propulsion. Engines with greater efficiency would result in longer mission duration, leading to cost savings and increased usefulness for UAV owners and...

  • Hydrogen for Heat: Utilizing Hydrogen for Long-Term Energy Storage in Northern Climates

    Creator:
    Villaverde, Gertrude
    Abstract:
    A long-term energy storage technology is necessary to utilize Oregon’s curtailed renewable energy, an issue the state faces, even with a low percentage of renewable energy in the energy mix. This report proposes a system design that details how hydrogen power-to-gas technology can be used in conjunction with the existing...

  • Quantification of Lipoic Acid InducedChanges in Nrf2-Mediated Stress Response

    Creator:
    Hobbs, Helen T.
    Abstract:
    As organisms age they lose the ability to respond to both exogenous and endogenous stresses, therefore placing them at a greater risk for the development of many diseases. The transcription factor Nrf2 is responsible for the induction of many oxidative stress response genes and therefore 3proteins. Additionally, Nrf2-mediated stress response...

  • An Accumulation of Senescent Cells May Contribute to Chronic Inflammation of the Mammalian Liver

    Creator:
    Sugiyama, Aaron
    Abstract:
    The aging process is a biological phenomenon in mammals that heavily contributes to the onset of chronic diseases. While there are many theories that attempt to explain the biological onset of aging, one emerging theory involves chronic inflammation. Chronic inflammation has been previously linked to several age-related diseases and is...

  • A Comparative Analysis of Rodent Species Shows Oxidative Stress Resilience and HSP70 Expression Levels Correlate with Species Longevity

    Creator:
    Sarker, Minhazur R.
    Abstract:
    Researchers of healthy aging have determined trends between a species’ body mass and its maximal life span (MLSP). Actual MLSPs are then compared to predicted MLSPs and reported as a longevity quotient (LQ). Long-lived mammals, such as humans and naked mole rats (NMR), have LQs ranging from 5.0 to 10.0,...

  • Activation and Nuclear Translocation of the Transcription Factor Nrf2 by the MAP Kinase Family

    Creator:
    Nguyen, Ngan H.
    Abstract:
    Eukaryotic cells have developed elaborate biochemical processes to counteract oxidative stress, electrophiles, or carcinogens due to environmental insults. One of these important cellular defense mechanisms is mediated by the transcription factor Nrf2 that have been shown to have decrease activity with age. While the process of which Nrf2 is involved...

  • Investigating the age-related loss of endoplasmic reticulum stress response

    Creator:
    Fallahi, Anahita
    Abstract:
    The endoplasmic reticulum (ER) is a crucial organelle in the cell where protein folding and processing occurs, and conditions that negatively affect ER functions are highly detrimental to the cell. The accumulation of unfolded/misfolded proteins in the ER leads to a condition known as ER Stress. The ER has developed...

  • Ibuprofen Treatment Causes NMDA and AMPA Receptor Hyperactivity in Female Wild Type and Heterozygous 5xFAD mice but not Males

    Creator:
    Rauenhorst, Jacob
    Abstract:
    With Alzheimer’s disease being the most prominent form of dementia, finding potential treatments for the disease is imperative. This study explored the non-steroidal anti-inflammatory drug ibuprofen as a potential treatment to normalize the hyperactive N-methyl-d-aspartate receptor (NMDAR) within the 5xFAD mice early in the disease pathology before cognitive decline. Female...

  • The Management Control System in a Growing Family Firm

    Creator:
    Henderson, Kali L.
    Abstract:
    Many firms start off as small family businesses which are controlled through the culture imprinted on employees by the founder. As the business grows, family owners and the executives that they hire, face a dilemma – how do they manage the trade-off between wanting to control the business in order...

  • Winning through Compromise? An Examination of Bipartisanship and Electability

    Creator:
    Ellingson-Cosenza, Elena J.
    Abstract:
    In America’s polarized politics, the language that congresspeople use matters. This thesis examines the use of bipartisan communications—in tweets and press releases—of members of the US House of Representatives as an electoral strategy for representatives in districts of varying competitiveness. A linear regression was conducted to analyze the relationship between...
