  • The long house

    Creator:
    Harris, Gregory A.
    Abstract:
    The Long House explores belonging and commitment. Jennifer Hawley, an American graduate student in linguistic anthropology, arrives in the early 1990s in Long Awan, a Dayak village in the remote highlands of Borneo. Her research concerns oral history among Punan families, traditionally nomadic, which have recently decided to settle in...

  • The morphological events during the self-reassembly of the sea urchin embryo in culture

    Creator:
    Hamada, Spencer Hiroshi
    Abstract:
    The gastrula of the sea urchin Strongylocentrotus purpuratus was dissociated into single cells. In culture these cells appeared apolar, but reassembled into quasi-normal embryos composed of structures with polarized cells. In this study emphasis was placed on those morphological events coincident with the reestablishment of a polar orientation within the...

  • An ultrastructural study of early cleavage in Mytilus

    Creator:
    Elvin, Patricia J.
    Abstract:
    Ultrastructural analysis and chemical inhibition studies were carried out on first cleavage of Mytilus zygotes to determine possible relationships between the mitotic apparatus and the cortex during polar lobe formation. The stages of mitosis correlated with the appearance of the polar lobe were first determined by light microscopy. The polar...

  • An ultrastructure study of oogenesis in the sea urchin, Strongylocentrotus purpuratus

    Creator:
    Chatlynne, Louise Geller
    Abstract:
    Oogenesis in the sea urchin Strongylocentrotus purpuratus was studied at the fine structural level, with special emphasis on the relationship between the two main cell types within the ovary: the egg cells and the nutritive phagocytes, or accessory cells. The nutritive phagocytes are flagellated cells with extensive pseudopods which store...

  • Heat flow results from plate boundary observatory boreholes in California

    Creator:
    McDonald, Kyle Joseph
    Abstract:
    An integral component to understanding lithospheric rheology, fault mechanics, and geodynamic processes is knowledge of the subsurface thermal regime. This study presents thermal data from 26 new borehole sites drilled during the installation of borehole strain meters as part of the Plate Boundary Observatory (PBO). These data extends existing coverage...

  • Continuous Flow Microwave-Assisted Synthesis as a Potentially Scalable Nanomanufacturing Approach

    Creator:
    Albuquerque, Gustavo Henrique T. C. de
    Abstract:
    The development of nanomaterials and the potential enhancement of their chemical, mechanical, electrical, and optical properties have led to the investigation of methods for their synthesis at lower cost with enhanced performance for next generation devices. Along with the pursuit of new materials that exhibit properties of interest, industry requires...

  • Studies of Chitin Nanofiber Production and Photoluminescent Biosilica from Diatoms with and without Germanium

    Creator:
    LeDuff, Paul A.
    Abstract:
    There is significant interest in harnessing the biosynthetic capacities of photosynthetic diatom microalgae for the production of unique bioinspired nanomaterials. Specifically, this research focuses on understanding the photoluminescent properties of diatom biosilica and β-chitin nanofiber production in diatoms. Diatoms are single-celled microalgae that possess intricately patterned biosilica shells called, frustules....

  • Heat Flow from a Vapor-Dominated Sublacustrine Vent Field Beneath Yellowstone Lake

    Creator:
    Favorito, Julia E.
    Abstract:
    Portions of Yellowstone Lake sit on top of a vigorous but not well understood hydrothermal system situated in a region of intense geologic and environmental forcings. A heat flow study conducted over the Stevenson Island Vent Field (SIVF), a vent field at the bottom of Yellowstone Lake underlain by an...

  • A histochemical study of oogenesis in the sea urchin, Strogylocentrotus purpuratus

    Creator:
    Chatlynne, Louise Geller
    Abstract:
    Oögenesis in the sea urchin Strongylocentrotus purpuratus was studied by histological methods and by histochemical techniques for polysaccharides, lipids, and nucleic acids Urchins were collected at Yaquina Head, Oregon at regular intervals between April 1966 and March 1967. An attempt was made to correlate seasonal variations in the coastal water...

  • Biological insertion of nanostructured germanium and titanium oxides into diatom biosilica

    Creator:
    Jeffryes, Clayton S.
    Abstract:
    There is significant interest in titanium oxide and germanium-silicon oxide nanocomposites for optoelectronic, photocatalytic, and solar cell applications. The ability of the marine diatom Pinnularia sp. to uptake soluble metal oxides from cell culture medium, and incorporate them into the micro- and nano-structure of their amorphous silica cell walls, called...
