  • Photochemistry of 6-alkenyl-2-cyclohexenones : synthetic studies towards precursors of ryanodol

    Creator:
    Wang, Bingbing
    Abstract:
    Regiochemistry of intramolecular [2+2] photocycloadditions of oxygenated 6-alkenyl-3-alkoxy-2-cyclohexenones is studied. Application of this methodology to construct a key intermediate [3.3.2] bicyclic skeleton of ryanodol is described as well. Irradiation of (3-butenyl)compounds 3, 11, 14 and of (4-pentenyl)compound 6 afforded exclusively the linear photoadducts 4, 12, 15 and 7 respectively. Irradiation...

  • Synthetic studies toward a total synthesis of paeoniflorigenin

    Creator:
    Hong, Zhenqiu
    Abstract:
    A new approach towards a total synthesis of paeoniflorigenin is discussed. The approach involves the application of regio- and stereoselective [2+2] photocycloaddition for the preparation of a key intermediate, cyclobutanone 86, and model studies on diiodosamarium (Sm12) mediated pinacol coupling of a diketone. Intermolecular [2+2] photocycloaddition of a,13unsaturated lactam 33...

  • Homeownership : still the American Dream? Perceptions of homeownership in the post crisis era

    Creator:
    Micek, Thomas P.
    Abstract:
    "The American Dream" is an expression familiar to all Americans and the realization of the American Dream is tied closely to homeownership (Clinton, 1995). The recent financial crisis, with the housing and financial markets at levels not seen since the Great Depression, has resulted in widespread unemployment, continually dropping home...

  • The effects of paralysis and oligohydramnios on morphological and behavioral characteristics of the rat fetus in utero

    Creator:
    Del Real, Carmen
    Abstract:
    Two experiments were conducted to assess the effects of paralysis and oligohydramnios on the development of the rat fetus. Behavior was suppressed in utero by subcutaneous injections of curare or puncture of the amniotic membrane leading to oligohydramnios. In Experiment 1, fetuses were treated with curare, oligohydramnios, both, or a...

  • Perceptions of residential grab bars among community dwelling seniors

    Creator:
    Thrall, Patti L.
    Abstract:
    Despite the perceived importance of grab bars to facilitate aging-in-place and healthy aging, many community-dwelling older adults do not have them installed. The aim of this study was to investigate predictors of grab bar installation among well-educated community dwelling seniors. Data was collected quantitatively through an electronic survey of Oregon...

  • Designed to fit : tailored technologies for medical practitioners

    Creator:
    de Brum, Silvina
    Abstract:
    Although electronic medical records systems (EMR) present promising benefits, they have not yet been widely adopted. A problem facing many EMR are that they are disruptive technologies; their complex hardware and software are not designed to account for the clinicians' characteristics and needs, thus, demanding a steep learning curve and...

  • Cytochrome P-450 monooxygenases in the mosquito, Culex pipiens

    Creator:
    Baldridge, Gerald D.
    Abstract:
    A sucrose density-gradient ultracentrifugation technique for obtaining microsomes has been developed. This technique has advantages over the classic differential centrifugation technique, in that it is faster, is better suited to work with small quantities of tissue, and offers the opportunity to work with a defined microsomal sub-cellular fraction, rather than...

  • B-Naphthoflavone induction and its effect on hepatic phospholipid metabolism in rainbow trout (Salmo gairdneri)

    Creator:
    Harris, Marcia Elaine
    Abstract:
    The induction of drug-metabolizing enzymes is a complex biochemical process manifested not only by increases in various cytochrome P-450 isozymes and related activities, but also by alterations in endoplasmic reticulum membranes. Little work has been done to examine how cytochrome P-450 inducing agents influence other cellular processes, such as phospholipid...

  • Dimensionality Reduction Techniques for Compositional Data : An Empirical Study

    Creator:
    George, Rogen
    Abstract:
    Compositional data is a type of data where the features are non-negative and always sum to a constant. This type of data is frequently encountered in many fields such as microbiology, geology, economics and natural language processing. Compositional data has unique statistical properties that makes it difficult to apply standard...

  • Counterfactual States for Atari Agents via Generative Deep Learning

    Creator:
    Olson, Matthew L.
    Abstract:
    Although deep reinforcement learning agents have produced impressive results in many domains, their decision making is difficult to explain to humans. To address this problem, past work has mainly focused on explaining why an action was chosen in a given state. A different type of explanation that is useful is...
