  • Natural products from tropical and temperate marine algae

    Creator:
    Bernart, Matthew W.
    Abstract:
    Following surveys of seaweeds in Oregon and the Caribbean, four algal species were selected for study on the basis of their crude extract biological activity or thin-layer chromatographic characteristics. Extracts were fractionated by normal phase chromatography, including high performance liquid chromatography (HPLC). Derivatives (methyl esters, acetates, and benzoates) of natural...

  • Habitat Use and Ecological Interactions of Invasive Lionfish in the Bahamas

    Creator:
    Davis, Alexandra C. D.
    Abstract:
    Invasive species are a growing global economic and ecological problem. Invasive Indo-Pacific lionfish (Pterois spp.) are known to have extreme negative effects on coral-reef communities in the Bahamas, so understating their distribution within and among reefs, what limits their local movements, and the effects they have on native prey species...

  • Flavor chemistry of popcorn

    Creator:
    Walradt, John Pierce
    Abstract:
    Popcorn was popped conventionally in oil and in a microwave oven without oil. Volatile components were collected by condensation of popper headspace gases and by vacuum steam distillation of a slurry of ground, popped corn in distilled water. The organic compounds were extracted from the aqueous condensate and vacuum distillate...

  • Information-theoretic Approach to Design and Evaluate Privacy-preserving and Fair Frameworks for Continuous High-dimensional Data

    Creator:
    Alsulaimawi, Zahir Ahmed Hussein
    Abstract:
    Deep learning is becoming the latest trend in sensitive applications, such as healthcare, criminal justice, and finance. As these new applications emerge, adversaries are circumventing them. Further, there have been concerns about the possibility of bias and discrimination in predictive applications. In order to address these issues, we propose an...

  • Paleoclimate, paleoventilation, and paleomagnetism as recorded in a 17kyr marine sediment record from the SE Alaska margin

    Creator:
    Davies, Maureen Helen
    Abstract:
    The deglacial behavior of the sub-Arctic North Pacific is poorly constrained, with many published records suffering from limited age control due to extensive post- depositional biogenic carbonate dissolution. Potential alternative dating methods could include the correlation of stable-isotopic and/or paleomagnetic secular variation records to an independently-dated regional template, however no...

  • Water Efficiency for Urban Landscapes in Semi-Arid Environments

    Creator:
    Martinson, Richard W.
    Abstract:
    Urban landscape water use is increasingly a focus of water conservation efforts. This is especially true in the arid and semi-arid regions of the western United States where increased demand, environmental concerns, and extended periods of drought have created chronic water shortages. However, until recently, little attention has been paid...

  • Immunological and physiochemical characterization of fish myosins

    Creator:
    Reed, Zachary H.
    Abstract:
    Increased sales of surimi seafood, with the majority as crabstick in the United States indicates that surimi based products are becoming more popular. With growing popularity, there is increased competition for market share. Under these circumstances, some companies may be willing to sacrifice product quality in order to facilitate manufacture...

  • Monte Carlo Radiation Transfer Simulations of Gamma Ray Burst Prompt Emission

    Creator:
    Parsotan, Tyler M.
    Abstract:
    Gamma Ray Bursts (GRBs) are the most energetic explosions in the Universe, producing up to $\sim10^{53}$ ergs of energy in the first few seconds of their emission -- the so-called prompt phase that is dominated by high energy X-ray and $\gamma$-ray photons. The very large luminosities released in these events...
