  • 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...

  • The Influence of Traditional Shoes, Minimal Shoes and Barefoot on Ankle Kinematics in Youth During Running

    Creator:
    Hartman, Hunter
    Abstract:
    Introduction: Research has demonstrated that minimal shoes may help prevent ankle injuries by mimicking natural barefoot running. It has been proven that minimal shoes may help adults prevent injuries in the correct conditions, but little is known about the effect of minimal and barefoot running on youth kinematics. Purpose: To...

  • 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...

    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...

    Kaiyala, Montana E.
    Abstract:
    Background: 250,000+ individuals injure an anterior cruciate ligament (ACL) in the United States annually. Individuals post-ACL surgical reconstruction (ACLR) are at elevated risk for ACL re-injury, potentially from kinematic and kinetic asymmetries. While studies have examined asymmetries at the hip and knee post-ACLR during landing, less is known about asymmetries...
