  • 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,...

  • Regulation of cnidarian–dinoflagellate mutualisms: Evidence that activation of a host TGFβ innate immune pathway promotes tolerance of the symbiont

    Creator:
    Detournay, Olivier, Schnitzler, Christine E., Poole, Angela, and Weis, Virginia M.
    Abstract:
    Animals must manage interactions with beneficial as well as detrimental microbes. Immunity therefore includes strategies for both resistance to and tolerance of microbial invaders. Transforming growth factor beta (TGFβ) cytokines have many functions in animals including a tolerance-promoting (tolerogenic) role in immunity in vertebrates. TGFβ pathways are present in basal...

  • 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...

  • Techno-economic analysis of algal lipid fuels

    Creator:
    Xiang, Xuwen
    Abstract:
    A techno-economic analysis (TEA) was performed to evaluate the technology, cost, and resource use for algal biofuel production based on today’s economics and technology. The basic goal of this study is to develop a model to calculate the mass and energy balances and costs to produce 10 million gal of...

  • 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...

  • On the Structure of the Orbit Spaces of Almost Torus Manifolds with Non-negative Curvature

    Creator:
    Dong, Zheting
    Abstract:
    An almost torus manifold $M$ is a closed $(2n+1)$-dimensional orientable Riemannian manifold with an effective, isometric $n$-torus action such that the fixed point set $M^T$ is non-empty. Almost torus manifolds are analogues of torus manifolds in odd dimension and share many of the characteristics of torus manifolds. For example, both...

    Abstract:
    In this paper we explore the eight geometries of Thurston's geometrization conjecture. We begin by discussing group actions, covering space topology, fiber bundles, and Seifert fiber spaces. We make precise the notion of a geometric structure. We then discuss the two dimensional geometries including a brief proof of the uniformization...

    Abstract:
    Currently, the technologies used to separate lignocellulosic biomass into its component parts (cellulose, hemicellulose, and lignin) and enzymatically hydrolyze the cellulose to glucose for conversion to ethanol could be improved economically and in terms of efficiency. A major impediment to utilizing the biomass is the presence of residual lignin. The...

  • Classifying seven dimensional manifolds of fixed cohomology type

    Creator:
    Montagantirud, Pongdate
    Abstract:
    Finding new examples of compact simply connected spaces admitting a Riemannian metric of positive sectional curvature is a fundamental problem in differential geometry. Likewise, studying topological properties of families of manifolds is very interesting to topologists. The Eschenburg spaces combine both of those interests: they are positively curved Riemannian manifolds...
