Magnetotelluric Constraints on Lithospheric Properties in the Southeastern United States

Creator:: Murphy, Benjamin S.
Abstract:: By inverting EarthScope long-period magnetotelluric (MT) data from the southeastern United States (SEUS), we obtain electrical conductivity images that provides key insights into the geodynamics of this region. Significantly, we resolve a highly electrically resistive block that extends to mantle depths beneath the modern Piedmont and Coastal Plain physiographic provinces....

Ocean Temperature Variability during the Late Pleistocene

Creator:: Hoffman, Jeremy Scott
Abstract:: This dissertation explores one overarching question relevant to the paleoclimate of the latest Pleistocene glacial cycle (approximately the last 130,000 years): “How did spatial and temporal evolution of ocean temperature, both at the surface and interior, relate to other parts of the climate system in the late Pleistocene?” Results from...

Development of thermosensitive injectable hydrogel and transdermal controlled release formulations for Tacrolimus

Creator:: Nguyen, Duc X.
Abstract:: TAC is the most commonly used medication in post transplantation maintenance immunosuppression therapy. TAC lipophilicity and its erratic oral absorption especially in the presence of food intake result in great intra- and interpatient pharmacokinetic variations. Complicated dosing and frequent required therapeutic monitoring is thought to be the main cause of...

The Relationship Between IGF-1 and Bone Turnover in a Non-Human Primate Model of Voluntary Alcohol Consumption

Creator:: Sattgast, Lara H.
Abstract:: Alcohol is a widely consumed, nonessential, bioactive nutrient with end-organ effects on the skeleton. Moderate levels of alcohol consumption are generally associated with increased bone mineral density (BMD), whereas higher intake levels result in reduced bone formation, bone loss, and increased risk for osteoporotic fracture. Given the negative impact of...

Evolutionary and Biochemical Studies of C₇-cyclitol Synthases and their Sunscreen Gene Clusters

Creator:: Osborn, Andrew
Abstract:: Sugar phosphate cyclases (SPCs) are enzymes involved in the biosynthesis of many important natural products. SPCs form a unique cyclitol during the early steps in the biosynthesis of many natural products. These natural products include rifamycin, which is chemically modified to rifampicin and used clinically as an antituberculosis drug, and...

Rational Fuel Design for Low Temperature Internal Combustion Engines

Creator:: Daly, Shane R.
Abstract:: This work introduces a new methodology to design transportation fuels offering improved efficiency and reduced emissions, aimed to complement both traditional and emerging engine technologies. Many of these emerging technologies are centered around exploiting low temperature combustion (LTC) strategies that offer improved efficiency and reduced emissions. However, a standardized fuel...

Utilization of the Zebrafish Model for Investigating Nitrated Polycyclic Aromatic Hydrocarbon Developmental Toxicity

Creator:: Chlebowski, Anna C.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are among the most widely known and studied environmental contaminants, originating from a range of natural and anthropogenic sources. PAHs are known to occur in the environment as complex mixtures, containing both unsubstituted PAHs, as well as a range of PAH derivatives. Among the less-studied of...

Process Intensification toward Reduced Exergy Destruction in Methane Upgrading

Creator:: Freiberg, Lucas J.
Abstract:: Exergy relates to thermodynamic value or usefulness in the universe. In this dissertation, three methods in the realm of "process intensification" are explored to reduce exergy destruction by equipment and processes that are used to convert and upgrade methane. Thermodynamic efficiency of a virtual heat exchanger is improved with a...

Ignition of Fuel Beds by Firebrands

Creator:: Bean, Derek R.
Abstract:: The severity of wildfires around the globe is increasing. At the same time, urban development is expanding outward into areas where severe fires occur. There is an increased risk of home loss to fires in areas where severe fires and urban expansion meet. Ignition of homes or nearby fuel is...

Novel System Design and Operational Strategies for the Production of Biofuels and Bioproducts

Creator:: Kadhum, Haider J.
Abstract:: Enzymatic hydrolysis is a critical process in the conversion of lignocellulosic biomass into biofuels and biochemicals. Achieving high efficiencies and productivity during the enzymatic hydrolysis of biomass is the key for the commercially viable process. Downstream processing challenges require high product titers which in turn require the use of high...
