  • Temperature stress, gene expression, and innate immunity at the onset of cnidarian-dinoflagellate symbiosis

    Creator:
    Schnitzler, Christine E.
    Abstract:
    The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...

  • Techno-economic and Life-cycle Analyses of Glucosamine and Lipid Production from Marine Diatom Cyclotella sp.

    Creator:
    Xiang, Xuwen
    Abstract:
    Currently the production of biofuel from algae is not economically competitive with petroleum fuel. However, co-production of high-value products may be able to justify the cost of large-scale algae cultivation. The basic goal of this study is to develop a techno-economic analysis (TEA) and Life-cycle assessment (LCA) for the production...

  • Life cycle assessment of algal biofuels

    Creator:
    Kirby, Bryan L.
    Abstract:
    This thesis consists of three studies to better understand the environmental sustainability potential for algal-based biofuels. Initially, a comparison of recent life cycle assessments (LCA) of theoretical full-scale algal biofuel facilities was developed. These studies include varying boundaries and scope, functional units, and technology maturity assumptions. The comparison converted results...

  • Assessment of Decentralized Wastewater Treatment System- Potential Impact on Water Quality

    Creator:
    Chavan, Padmaja Ramesh
    Abstract:
    Watershed analysis is a method used to collectively characterize ecosystem elements present within a watershed. Wastewater flow and pollutant content help to define the appropriate wastewater treatment system necessary to treat the wastewater within the watershed. Watershed monitoring aids to investigate the potential contamination through analysis of surface waterbodies. Major...

  • The effects of a 7-month high impact jumping intervention on bone mass in pre-pubescent boys and girls

    Creator:
    Fuchs, Robyn K.
    Abstract:
    High impact loading activities such as jumping, performed during childhood is advocated as one preventive method for increasing peak bone mass. Thus, we conducted a randomized intervention to examine the effect of high impact loading on bone mass in 34 pre-pubescent boys and girl over a seven month period. Participants...

  • Functional polymers and proteins at interfaces

    Creator:
    Schilke, Karl F.
    Abstract:
    Functional polymers and proteins at interfaces and surfaces are of fundamental importance for biomaterials, biocatalysis and microreactor applications. Candida antarctica lipase B immobilized on poly-DL-tryptophan tethers showed 30x higher specific activity in aqueous and non-aqueous media than the same enzyme adsorbed or covalently bound directly to the surface. An excess...

  • New application of crystalline cellulose in rubber composites

    Creator:
    Bai, Wen
    Abstract:
    Rubber without reinforcement has limited applications. The strength of reinforced rubber composites can be ten times stronger than that of unreinforced rubbers. Therefore, rubber composites are widely used in various applications ranging from automobile tires to seals, valves, and gaskets because of their excellent mechanical elastic properties. Silica and carbon...
