Exchange Of Polar Lipids From Adults To Neonates In Daphnia Magna: Perturbations In Sphingomyelin Allocation By Dietary Lipids And Environmental Toxicants, Namrata Sengupta, Delaney C. Reardon, Patrick D. Gerard, William S. Baldwin May 2017

Exchange Of Polar Lipids From Adults To Neonates In Daphnia Magna: Perturbations In Sphingomyelin Allocation By Dietary Lipids And Environmental Toxicants, Namrata Sengupta, Delaney C. Reardon, Patrick D. Gerard, William S. Baldwin

Publications

Because xenosensing nuclear receptors are also lipid sensors that regulate lipid allocation, we hypothesized that toxicant-induced modulation of HR96 activity would alter lipid profiles and the balance between adult survival and neonate production following exposure in Daphnia magna. Adult daphnids were exposed to unsaturated fatty acid- and toxicant- activators or inhibitors of HR96 and later starved to test whether chemical exposure altered allocation toward survival or reproduction. The HR96 activators, linoleic acid and atrazine, decreased reproduction as expected with concomitant changes in the expression of HR96 regulated genes such as magro. The HR96 inhibitors, docosahexaenoic acid (DHA) and triclosan, …

Annotation Of The Nuclear Receptors In An Estuarine Fish Species, Fundulus Heteroclitus, William S. Baldwin

Publications

The nuclear receptors (NRs) are ligand-dependent transcription factors that respond to various internal as well as external cues such as nutrients, pheromones, and steroid hormones that play crucial roles in regulation and maintenance of homeostasis and orchestrating the physiological and stress responses of an organism. We annotated the Fundulus heteroclitus (mummichog; Atlantic killifish) nuclear receptors. Mummichog are a non-migratory, estuarine fish with a limited home range often used in environmental research as a field model for studying ecological and evolutionary responses to variable environmental conditions such as salinity, oxygen, temperature, pH, and toxic compounds because of their hardiness. F. heteroclitus …

Effects Of Phosphorus Concentration On Algal Composition And Bioprocessing Potential, Cassidy Laird May 2017

Effects Of Phosphorus Concentration On Algal Composition And Bioprocessing Potential, Cassidy Laird

All Theses

As an increasing amount of carbon dioxide (CO2) and other greenhouse gases pollute the lower atmosphere, and as various chemicals and elements pollute the water and soil, many search for potential solutions. One possibility is bio-mitigation using algae. Algae use CO2 and common polluting nutrients like nitrogen and phosphorus to grow. The growth, in turn, produces biomass and other byproducts that are converted to commodities such as biofuels, pharmaceuticals, cosmetics, and food supplements. Cosmetics and gelatin products are commonly sold, while other chemical products have bottlenecks in the process that require further research to make it marketable. The potential bioproducts …

Toxicity Of Microplastics To Aquatic Organisms, Sarah Au May 2017

Toxicity Of Microplastics To Aquatic Organisms, Sarah Au

All Dissertations

Plastic is used in products that span from cutlery to the main components in automobiles, and airplanes. Both municipal solid waste streams and marine debris are comprised of largely plastic products, and as annual global plastic production and use is unlikely to decrease, the presence of plastic in the environment will likely increase. Microplastics (MPs) are plastic fragments that have at least one dimension that is less than 5 mm, and have been found throughout water bodies around the world. MPs are in the same size fraction as most sediment particles and microorganisms, allowing them to be easily ingested by …

Mechanical Behavior Of A Bio-Inspired Chondrichthyan Feeding Mechanism: Influence Of Dentition Patterns, Garrett Hall May 2017

Mechanical Behavior Of A Bio-Inspired Chondrichthyan Feeding Mechanism: Influence Of Dentition Patterns, Garrett Hall

All Theses

Despite the relative compliance of cartilage compared to bone, many chondrichthyans are capable of thriving at a variety of extremes, including: living in high-pressure environments, supporting massive body weights and muscular loads, or feeding on hard-bodied prey. Although there is extensive literature on shark feeding mechanics, cranial anatomy, and tooth structure and function, questions still surround the structural foundation of the chondrichthyan feeding mechanism in polydontic models. Consequently, the efficacy of shark jaws to withstand loads experienced during feeding is a topic of interest among biologists and engineers alike. Polydontic bio-inspired models were developed through additive manufacturing and tested in …

The Effect Of Freezing And Refrigeration On Food Quality, Mary Catherine Anne Remington May 2017

The Effect Of Freezing And Refrigeration On Food Quality, Mary Catherine Anne Remington

All Theses

Food shelf-life extension is important not only to food manufacturers, but also to home refrigeration/freezing appliance companies, whose products affect food quality and food waste. While freezing and refrigerating both extend the shelf life of foods, food quality deterioration continues regardless of the preservation method. Quality attributes of frozen Atlantic salmon (Salmo Salar) were analyzed at different freezing rates to core holding temperatures of -106°F/-77°C, -20°F/-29°C, 0°F/-18°C, 10°F/-12°C, and 20°F/-7°C.

Phytophthora Species Associated With American, Chinese, And Backcross Hybrid Chestnut Seedlings In Field Sites In The Southeastern United States, Suzette Ruth Sharpe May 2017

Phytophthora Species Associated With American, Chinese, And Backcross Hybrid Chestnut Seedlings In Field Sites In The Southeastern United States, Suzette Ruth Sharpe

All Theses

Phytophthora root rot was first described on American chestnut (Castanea dentata) in a preliminary report in 1932 and the causal agent was tentatively and erroneously identified as P. cambivora. Soon after, the causal agent was correctly identified as P. cinnamomi and, since that time, P. cinnamomi has been the only species reported to cause Phytophthora root rot on the American chestnut. In the early 1980s, The American Chestnut Foundation initiated a backcross breeding program to develop chestnut trees that had resistance to Cryphonectria parasitica which causes chestnut blight. In the early 2000s, backcross hybrid chestnut seedlings ([American …

It Wasn't Even A Question If I Would Be A Fan: Major League Baseball Team Fandom And Intergenerational Relationships, Lauren Leigh Watts May 2017

It Wasn't Even A Question If I Would Be A Fan: Major League Baseball Team Fandom And Intergenerational Relationships, Lauren Leigh Watts

All Theses

The current study aims to explore new avenues of fan studies and family communication research. Current research in both disciplines does not address in-depth how individuals become fans of certain sports teams and how family can play a role in the development of fandom. Communication scholars have explained that family legacies and stories are passed down through narratives, also known as family storytelling. Studies show that individuals come to know themselves and the world through family stories that have been passed down from generation to generation. Sport is prominent in American culture, and baseball is known as America's Pastime. This …

The Relationship Between Physical Activity And Psychosocial Health In Adolescent Girls And Their Mothers, Kellie Walters May 2017

The Relationship Between Physical Activity And Psychosocial Health In Adolescent Girls And Their Mothers, Kellie Walters

All Dissertations

In most western countries, obesity and sedentary behavior are a major health concern. Research demonstrates a clear connection between one's physical and emotional health (e.g., body image) and as such, many community programs now focus on the "whole person" rather than just physical wellbeing. When looking at the population as a whole, the most health disparate group is adolescent girls. Compared to any other cohort, adolescent girls are the most sedentary, obese, and likely to suffer from psychosocial distress such as anxiety and/or depression. As a result, there is a need for further research into adolescent girls' physical and emotional …

The Impact Of Socioeconomic Status On 30-Day Hospital Readmissions In South Carolina, Joseph Alexander Ewing May 2017

The Impact Of Socioeconomic Status On 30-Day Hospital Readmissions In South Carolina, Joseph Alexander Ewing

All Dissertations

The current method for calculating excess hospital readmission penalties does not incorporate measures of socioeconomic status, thereby leaving nonprofit teaching and safety net hospitals vulnerable to financial reimbursement penalties due to exogenously determined heterogeneous patient populations. The literature has shown that socioeconomically disadvantaged groups are readmitted to nonprofit teaching hospital's in higher proportions than more advantaged groups. Increased readmission to nonprofit teaching hospitals has been linked with cost shifting from those unable to pay to those with the ability to pay for medical care. Therefore, a new method for determining hospital excess readmission penalties is needed to reduce the incentive …

Thermal Inactivation Of Desiccation-Adapted Salmonella Enterica In Physically Heat-Treated Poultry Litter Used As Biological Soil Amendments, Zhao Chen

All Dissertations

Poultry litter is usually recycled into the soil to improve the structure and fertility of agricultural land. As an important source of nutrients for crop production, poultry litter may possibly contain a variety of human pathogens that can threaten humans who consume the contaminated produce. The composting process can inactivate pathogens while creating a biological soil amendment beneficial for application to arable agricultural land. Some pathogens may have the potential to survive for long periods of time in raw poultry litter or its inadequately composted products after land application, and a small population of pathogenic cells may even regrow to …

Landscape Manipulatives: A Study Of Math Gardens And Learning Outcomes In Middle School Mathematics Education Research, Yang Song May 2017

Landscape Manipulatives: A Study Of Math Gardens And Learning Outcomes In Middle School Mathematics Education Research, Yang Song

All Dissertations

Human beings, especially children, need natural environments and outdoor play for their physical, mental, and spiritual well-being (Louv, 2008). Even though parents and teachers recognize the value of outdoor play, schoolchildren spend a diminishing amount of time engaging in outdoor activities (Clements, 2004). Furthermore, addressing strict state learning standards is the first priority for schools. Outdoor activities are often seen as extracurricular to those subjects typically emphasized and tested. As a result, outdoor landscapes such as science gardens, playgrounds, and experiential classrooms are often underutilized, discouraged since they can take away from more important, standard forms of pedagogy. Thus, traditional …
