  • The Influence of Microbial Communities on Spatiotemporal Elemental Cycling in Coastal Margins Revealed by Community- and Population-level Genomics and Proteomics

    Creator:
    Kieft, Brandon P.
    Abstract:
    Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...

  • A General Purpose Agent-Based Blackboard Optimization Method Applied to Sodium Fast Reactor Design and Analysis

    Creator:
    Stewart, Ryan H.
    Abstract:
    We present a novel multi-objective optimization methodology built upon a multi-agent blackboard framework. This multi-agent blackboard system (MABS) synthesizes blackboard architectures, multi-agent environments, and optimization theory. The blackboard architecture creates the framework for initializing, storing, and solving a multi-objective optimization problem. Multiple agents allow for an optimization problem to be...

  • Optimization of staged rankine energy conversion cycles for high efficiency

    Creator:
    Simmons, Larry Dean
    Abstract:
    Because of the fuel crisis and problems associated with thermal pollution there is new impetus and urgency for developing more efficient energy conversion systems for power generation. A preliminary analysis was undertaken to determine the potential of staged Rankine cycle systems for substantially higher efficiency. It was necessary to optimize...

  • Comparative genomics of Vibrio and characterizing microbial communities at a shellfish hatchery

    Creator:
    Delgado, Hanna
    Abstract:
    Vibrio bacteria are commonly found in freshwater, marine, and estuarine environments. Members of this genus can exist in commensal relationships with marine animals or as planktonic bacteria, however, they are well known for their roles as pathogens towards humans and animals. In this dissertation, I investigated aspects of host-bacteria relationships...

  • Effects of Anthropogenic Stressors on Seagrass and Coral Microbiomes

    Creator:
    Wang, Lu
    Abstract:
    Seagrasses and coral reefs play important roles in nutrient cycling, coastal protection, and maintaining marine biodiversity. However, these coastal marine organisms are declining globally due to anthropogenic stressors, such as rising ocean temperatures, ocean acidification, and eutrophication. These organisms live in close association with their microbiomes, which can be beneficial...

  • In vivo Reactions of Tetrazines Incorporated through Genetic Code Expansion

    Creator:
    Blizzard, Robert J.
    Abstract:
    The inverse electron demand Diels Alder reaction between tetrazines and strained alkenes is an exceptionally useful tool in functionalizing to biomolecules since it is orthogonal to the chemistry of most living systems and have exceptionally high rate constants. In particular reactions between strained trans-cyclooctenes (sTCO) and tetrazines can achieve second...

  • Breeding and genetics of lilacs and hardy hibiscus

    Creator:
    Lattier, Jason D.
    Abstract:
    Lilacs are a group of ornamental trees and shrubs in the Oleaceae family consisting of 22 to 30 species. There are six series within genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Fertility and cross-compatibility among cultivars, species, and series have yet to be formally investigated. Over three years,...

  • Linking phylogenetic identity and biogeochemical function of uncultivated marine microbes with novel mass spectrometry techniques

    Creator:
    Bryson, Samuel J.
    Abstract:
    The combined activities of diverse heterotrophic marine microorganisms significantly shape global biogeochemical cycles, but models of these activities are currently limited to aggregate microbial community processes, and it remains unclear how community structure and the functional roles of specific microbial taxa should be integrated into these models. Therefore, understanding the...

  • Methodology for evaluating mechanical power in small-scale WEC experiments

    Creator:
    Simmons, Asher
    Abstract:
    Wave energy converters (WECs) are a broad class of emerging technology that converts hydrokinetic energy into some other useful form, such as electricity. The last stage in this transformation, the power take-off (PTO) subsystem, is often not experimentally evaluated until half-way through the recommended development process. This delay in evaluation...

  • Employing Genetic Code Expansion Tools to Elucidate Disease Mechanisms and Generate New Therapeutics

    Creator:
    Van Fossen, Elise M.
    Abstract:
    In biology, function and disease are closely intertwined, requiring the coordination of hundreds of intricate chemical reactions. Interdisciplinary cooperation between chemical and biological approaches is necessary to decipher the chemical links between physiological and pathological conditions. In this arena, the precision tools made possible with chemical biology can manipulate and...
