  • 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...

  • Development of novel oral enteric-coated aquaculture vibrio vaccines

    Creator:
    Wong, George Kaon
    Abstract:
    An oral Vibrio vaccine for salmonids was developed. The vaccine was produced by spray coating lyophilized formalin-killed whole cells of Vibrio anguillarum (VA LS 1- 74) onto non-pareil sugar beads. Then methacrylic acrylic acid copolymer (Eudragit L-30D) was applied as an enteric protective coating. Using x-ray radiographic techniques, it was...

  • Management strategies and time use in food preparation in two-parent, two-child Utah families

    Creator:
    Steggell, Carmen Dobson
    Abstract:
    The management of the home has been a central component of Home Economics since the early 1900s. It is, however, an enigmatic behavior that has not yielded easily to research. Recognizing that meal provision and food consumption by families incorporate management processes and occur on a regular and frequent basis,...

  • Low noise FSCL digital circuits for decimation filter

    Creator:
    Wong, Man Wa
    Abstract:
    A new circuit technique called Folded Source Coupled Logic (FSCL) has been developed to implement the digital section of mixed-signal IC applications. This FSCL circuit technique offers the advantage of low overlap current spikes during the switching transitions of conventional CMOS gates. This overlap current spike has become one of...

  • Controls on movement of selected landslides in the Coast Range and western Cascades, Oregon

    Creator:
    Wong, Bernard Bong-Lap
    Abstract:
    The movement characteristics of five landslides are compared and interpreted based on records of approximately 10-years duration. Condon landslide in the Oregon Coast Range has consistently exhibited brief (1 - 8 days) movement episodes in wet winter months, separated by long periods of no movement. The translatory movement is probably...

  • Defining leisure and recreation in Malaysia

    Creator:
    Wong, Jenny Lai Ping
    Abstract:
    The fundamental aim of this study was to determine how Malaysians define both leisure and recreation. Two ethnic groups, Chinese and Malays, and rural and urban variants of these groups were included in the sample. The other objective was to determine if there were differences in the definitions due to...

  • Automethylation : a response to enzyme aging

    Creator:
    Lindquist, Jonathan A.
    Abstract:
    This is the first study to explore the ability of an enzyme to recognize and repair spontaneous age-dependent damage to its own sequence. Protein (D-aspartyl/L-isoaspartyl) carboxyl methyltransferase (PCM) is known to repair damage that arises from a spontaneous isomerization of aspartyl and asparaginyl residues in other proteins during aging. As...

    Creator:
    Rico-Pena, Delmy del Carmen
    Abstract:
    The use of edible coatings in combination with antimicrobial agents enhances the microbial stability of foods. In this study we evaluated the potassium sorbate and sorbic acid permeability of an edible methylcellulose (MC) - palmitic acid (PA) film with a MC:PA ratio of 3:1. Permeability cell measurements were used to...

  • Binding and assembly of H5 (and the globular domain of H5) onto DNA

    Creator:
    Carter, George John
    Abstract:
    In order to better characterize linker histone interactions with DNA, avian erythrocyte-specific linker H5 and the trypsin-resistant globular domain of H5 (GH5) were used in DNA binding studies. To begin, H5 displayed a considerably higher binding affinity for DNA than the isolated globular domain (GH5), supporting the importance of the...
