  • α-tocopherol is specifically delivered to human skin : studies using deuterium-labeled α-tocopherol

    Creator:
    Vaule, Heather D.
    Abstract:
    The relative enrichment of skin sebaceous gland lipids with deuterium-labeled α-tocopherol was compared with plasma enrichment to evaluate the delivery of vitamin E to skin. For the first week of this study, each subject consumed a daily dose of deuterated vitamin E (150 mg of an equimolar mixture of RRR-α-[5-(C²H₃)]-(d₃)...

  • Zooplankton of the Galapagos Islands

    Creator:
    Figueroa, Diego
    Abstract:
    The marine climate of the Galapagos is spatially and seasonally heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has never been done. This study is an initial effort to establish the distribution and community structure of zooplankton in the Archipelago. I collected zooplankton samples by vertical tows over the Galapagos...

  • Zinc tin oxide thin-film transistor current mirror circuits

    Creator:
    Feller, Layannah Elizabeth
    Abstract:
    The central focus of this thesis is the design, fabrication and characterization of amorphous oxide semiconductor (AOS) thin-film transistor (TFT) current mirrors. The thin-film deposition and circuit fabrication methods used to realize zinc tin oxide (ZTO) TFT current mirrors are addressed in order to elucidate the processing challenges for this...

  • Zinc tin oxide thin-film transistor circuits

    Creator:
    Heineck, Daniel Philip
    Abstract:
    The primary objective of this thesis is to develop a process for fabricating integrated circuits based on thin-film transistors (TFTs) using zinc tin oxide (ZTO) as the channel layer. ZTO, in contrast to indium- or gallium-based amorphous oxide semiconductors (AOS), is perceived to be a more commercially viable AOS choice...

  • Zebrafish models for translational neuroscience research: from tank to bedside

    Creator:
    Stewart, Adam Michael, Braubach, Oliver, Spitsbergen, Jan, Gerlai, Robert, and Kalueffl, Allan V.
    Abstract:
    The zebrafish (Danio rerio) is emerging as a new important species for studying brain mechanisms and its deficits. Focusing on selected CNS disorders (brain cancer, epilepsy and anxiety) and using them as examples, we discuss the value of zebrafish models in translational neuroscience, and their contribution to neuroimaging, circuit-level and...

  • Zeatin O-xylosyltransferase in Phaseolus vulgaris : immunological and molecular analyses

    Creator:
    Martin, Ruth C.
    Abstract:
    Cytokinins are a group of plant hormones mediating cell division and differentiation. Zeatin is a naturally occurring and highly active cytokinin that is rapidly metabolized in Phaseolus seeds. The metabolites and enzymes mediating the conversion have been studied extensively. Zeatin metabolic enzymes may be utilized in studying the regulation of...

    Abstract:
    This dissertation describes patterns in epiphytic macrolichen community composition along a nitrogen deposition gradient in the Yosemite region of the Sierra Nevada in California. This region is part of the largest federal air quality Class 1 designated air-shed in the western United States, covering the entire crest of the Sierra...

  • Yeast extractives in the nutrition of San Francisco sourdough bacteria (Lactobacillus sanfrancisco)

    Creator:
    Berg, Ronald Wayne
    Abstract:
    A laboratory-prepared hot-water extract of yeast is required for vigorous growth of San Francisco sourdough bacteria (Lactobacillus sanfrancisco) in pure culture. This requirement was examined with the goal of determining what is unique about fresh yeast extractives (commercial extractives exhibit much lower growth promoting activity), and which components of fresh...

  • Xenobiotic biotransformation in aquatic organisms

    Creator:
    Schlenk, Daniel K.
    Abstract:
    Aquatic animals are exposed to a variety of natural and anthropogenic xenobiotics. Biotransformation of xenobiotics was examined in three aquatic animals: a primitive mollusc (chiton); a shellfish which is an important human food source (oyster); and, a lower vertebrate model for toxicological studies (rainbow trout). Since digestive glands of Cryntochiton...

  • X-ray imaging and analysis techniques for quantifying pore-scale structure and processes in subsurface porous medium systems

    Creator:
    Wildenschild, Dorthe and Sheppard, Adrian P.
    Abstract:
    We report here on recent developments and advances in pore-scale x-ray tomographic imaging of subsurface porous media. Our particular focus is on immiscible multi-phase fluid flow, i.e., the displacement of one immiscible fluid by another inside a porous material, which is of central importance to many natural and engineered processes....
