  • The Role of Cellular Senescence in the Development of Alzheimer's Disease

    Creator:
    Riordan, Ruben
    Abstract:
    Alzheimer’s Disease (AD) is a neurodegenerative pathology currently affecting nearly 44 million individuals worldwide, yet there are not currently any effective treatments or preventions for AD despite the rapid development in our understanding of the disease over the last four decades. The medical and sanitary innovations of the last century...

  • Evaluating the Effect of Emotions on Student Learning using Prescriptive and Open-ended Lab Activities for a Lean Manufacturing Engineering Course

    Creator:
    Perez, Maritza
    Abstract:
    Research has shown that emotional connections during lab activities increase learning in chemistry and physics courses. However, little research has examined the effects of emotion in engineering courses, and these studies have recognized a dearth of research examining the ability of students to apply engineering concepts in real-world applications based...

  • Glyphosate-resistance in Italian ryegrass (Lolium multiflorum): evaluation and investigation of the mechanisms of resistance

    Creator:
    Perez-Jones, Alejandro
    Abstract:
    A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....

  • Risk and Uncertainty Quantification Methods in Electrical Power Systems

    Creator:
    Johnson, Brandon S.
    Abstract:
    Load flow studies are one of the most essential engineering applications for grid operators because they provide a clear picture of the operating conditions of the power system. Traditionally, the load flow problem is assumed to be deterministic; that is, the system variables contain no randomness. Unfortunately, this assumption is...

  • Characterizing PM2.5 with Different Source Contributions

    Creator:
    Perez, Allison Mae S.
    Abstract:
    Ubiquitous fine particulate matter (PM2.5) exposures significantly impact global public health, yet little is known about the mechanisms causing these known adverse health effects. Oxidative stress due to PM2.5 associated chemical constituents, such as polycyclic aromatic hydrocarbons (PAHs), is a proposed possible mechanism for PM2.5 mediated health effects. Variations in...

  • The Discourse of Demographic Diversity in U.S. Natural Resources Scholarly Literature: A Multi-Methods Qualitative Study

    Creator:
    Brown, Jasmine K.
    Abstract:
    Racial, ethnic and gender diversity have been long term topics of discussion in natural resources. Yet to date, there has not been a comprehensive review of the existing literature within the discourse of demographic diversity. Therefore, I conducted a systematic review of demographic diversity in the disciplines of forestry, fisheries,...

  • Oxidative stress in amyotrophic lateral sclerosis : the role of cellular senescence and glutathione

    Creator:
    Beilby, Pamela R.
    Abstract:
    Amyotrophic lateral sclerosis (ALS) is a devastating neurological disorder characterized by neuromuscular junction decay, motor neuron death, progressive paralysis, and eventually death of the individual, usually by respiratory failure. Oxidative stress is a prominent hallmark of the disease and is often accompanied and exacerbated by mitochondrial dysfunction and neuroinflammation. This...

  • Evolutionary Genomic Responses to Mitochondrial Dysfunction in Caenorhabditis elegans

    Creator:
    Wernick, Riana I.
    Abstract:
    Understanding the impact of mitochondrial dysfunction on genome evolution has the potential not only to provide new insights on the basic evolutionary processes influencing mitochondrial and nuclear genomes, but may also reveal novel avenues for evolutionary adaptive recovery from harmful mutations. Aberrant mitochondrial activity is fundamental to the pathology of...

  • Structural Insights into Novel Sugar Phosphate Cyclases and Flavoenzymes

    Creator:
    Kean, Kelsey M.
    Abstract:
    The function of a protein is defined by its three-dimensional structure, and in understanding the three-dimensional structure of a protein, we gain an understanding of its function and mechanism. Protein structures, especially at high resolution, can provide detailed insights into many elements of enzyme function and catalysis – identifying residues...

  • Investigating connections between the circadian system and aging in Drosophila melanogaster

    Creator:
    Long, Dani M.
    Abstract:
    Circadian clocks coordinate molecular, cellular, physiological, and behavioral processes with the 24-hour solar day. While clock functions are well understood in young animals, it is not clear how aging or neurodegenerative disease affects the various levels of the circadian system. A common symptom of many neurodegenerative diseases including Alzheimer’s disease...
