From The Social Margins To The Center: Lebanese Families Who Arrived In South Carolina Before 1950, Elizabeth Whitaker Dec 2006

From The Social Margins To The Center: Lebanese Families Who Arrived In South Carolina Before 1950, Elizabeth Whitaker

All Theses

The Lebanese families who arrived in South Carolina found themselves in a different environment than most had anticipated. Those who had spent time elsewhere in the U.S. found predominantly rural and predominantly Protestant South Carolina to be almost as alien as they or their parents had found the United States due partly to the religious differences and partly to the cultural differences between the Northeast, where most of them had lived for at least a few years after arriving in the United States, and the Southeast. Most of these new arrivals eventually found success and some degree of acceptance, but …

Pro-Inflammatory Properties Of Flavobacterium Columnare Cells And Products On Channel Catfish (Ictalurus Punctatus) Neutrophils, Shannon Billings

All Theses

Flavobacterium columnare and Edwardsiella ictaluri are the leading causes for losses in the aquaculture industry. The losses from the diseases caused by these pathogens total $2.5 million for catfish and $100 million for total aquaculture. F. columnare's infection rates and stressors associated with outbreaks have been well-characterized, but the specific inflammatory responses of catfish neutrophils to the bacteria have not been studied. The objective, therefore, was to investigate the pro-inflammatory effects of the outer membrane proteins, extracellular products, and whole live bacteria, heat-killed (HK), and formalin-killed (FK) F. columnare and E. ictaluri to determine the effects on channel catfish phagocyte …

Elevated Neutral-To-Earth Voltage In Distribution Systems Including Harmonics, Jian Jiang Dec 2006

Elevated Neutral-To-Earth Voltage In Distribution Systems Including Harmonics, Jian Jiang

All Dissertations

The elevated neutral-to-earth voltage (NEV), and the related phenomenon called stray voltage, is analyzed in multigrounded distribution systems. Elevated NEV is typically caused by fundamental frequency currents returning to the source via the neutral conductor and earth. However, harmonic distortion is also found to contribute to elevated NEV. A multiphase harmonic load flow algorithm is developed to examine the effects of various factors on the NEV, including unsymmetrical system configuration, load unbalance and harmonic injection. To fulfill this objective, the system modeling is adapted to include the neutral conductor into the component equivalent circuit. The overhead transmission line is remodeled …

Development Of A Cellular Fiber Spinning Technology For Regenerative Medicine, Willie Jones Dec 2006

Development Of A Cellular Fiber Spinning Technology For Regenerative Medicine, Willie Jones

All Theses

In order to prove that our textile hollow fiber spinning apparatus was adequate for cellular encapsulation, we confirmed the viability and metabolic activity of green fluorescent protein (GFP) labeled bovine mammary epithelial cells (MAC-Ts) that were encapsulated in either the wall or lumen of alginate fibers. After a 21 day in vitro macroscopic evaluation, no decrease in fluorescence was observed; and it was determined that MAC-Ts encapsulated under both methods produced lactic acid and consumed glucose. Histomorphological analyses revealed that the diameter of the MAC-Ts increased under both encapsulation scenarios, with little to no evidence of cell cluster propagation. Based …

Sorting Through Distortion, Kathryn Hutter Dec 2006

Sorting Through Distortion, Kathryn Hutter

All Theses

The relationship of the recurrent visual signals in contemporary culture and the physical routine of living in the culture begin to build as layers in the fabric or patterns of everyday. My use of pattern (both mass produced fabric, and painted surface) imitates the repetitious nature of visual stimuli in American culture as well as the viewer's familiarity with object and image recognition. I investigate the language of signals and human thinking relying heavily on the viewer's link to familiarity and how that may provoke them to read the paintings. To do this, I draw directly from the use of …

All Dissertations

Determining the consequences of human impact on our current and future climate is proving to be to be one of the greater challenges in modern biology. Current global models employing coupled atmosphere and terrestrial carbon feedbacks range in their predictions from the inconsequential to that of vast food shortages and species extinctions. However, there is hope that the emergence of new molecular approaches will revolutionize our understanding of plant and animal responses to a changing environment, allowing for higher predictive power when scaling up from the level of the individual to ecosystem-scale processes. This dissertation is an initial attempt for …

Stabilization Of Vascular Elastin By Treatment With Tannins, Jason Isenburg Dec 2006

Stabilization Of Vascular Elastin By Treatment With Tannins, Jason Isenburg

All Dissertations

Elastin is an important component of the extracellular matrix that endows cardiovascular tissue with the ability to extend and recoil repetitively. It has been shown that elastin may be vulnerable to enzymatic degradation and calcification in certain pathological cases. As a result, elastin degeneration may be associated with the failure of tissue-derived cardiovascular devices, such as bioprosthetic heart valves, as well as the development and progression of aortic aneurysms, a disease associated with progressive connective tissue degeneration of the arterial wall. Therefore, an elastin stabilizing agent may be beneficial for both applications. As such, our objectives for elastin stabilization are …

The Role Of Natural And Sexual Selection In The Origin And Maintenance Of Divergence Within And Between The Mexican Sailfin Mollies, Poecilia Velifera And P. Petenensis, Shala Hankison

All Dissertations

Understanding speciation remains a holy grail of evolutionary biology. One useful approach is studying the evolutionary mechanisms important in population divergence to infer the mechanisms important in speciation. This method is especially useful when closely related species can be compared to determine whether intraspecific differences parallel interspecific differences. I studied population divergence in two species of Mexican sailfin mollies, Poecilia velifera and P. petenensis. These closely related species are particularly useful for this type of study, as they live in habitats that may differ in the importance of natural selection. In addition, these species may differ in the importance …

Eliminating Listeria Monocytogenes In Packed Ready-To-Eat Poultry Products By Combining In-Package Pasteurization With Nisin And/Or Lysozyme, Sunil Mangalassary

All Dissertations

Listeria monocytogenes is a significant food-borne pathogen particularly associated with ready-to-eat (RTE) meat and poultry products which can grow and multiply at refrigeration temperatures. In-package pasteurization is an effective post-lethality intervention to reduce microbial contamination of RTE meat products. Enhancing the efficiency of in-package pasteurization is vital in reducing the L. monocytogenes population as well as in preserving the quality of the meat product. The first section of the dissertation research evaluated the effect of product thickness on the surface heating rate and final surface temperature during in-package pasteurization of vacuum-packaged bologna. Three thicknesses (4, 12, and 20 mm), corresponding …

Identification Of The Rassf3 Gene As A Potential Tumor Suppressor Responsible For The Resistance To Mammary Tumor Development In Mmtv/Neu Transgenic Mice, Isabelle Jacquemart

All Dissertations

The MMTV/neu transgenic mouse line is a well-documented animal model for studying HER2/neu-related breast cancer. It has been reported that a small percentage, approximately 20%, of the virgin female MMTV/neu mice seems resistant to the development of mammary gland adenoma, despite the overexpression of the neu oncogene.
To identify the factors that are responsible for the tumor resistance in these MMTV/neu female transgenic mice, comparative genetic profiling was used to screen the alterations in gene expression in the mammary gland. A novel gene named the RAS Association domain (RalGDS/AF-6) Family 3 (Rassf3), which belongs to a family of RAS effectors …

Meaningful Activities For Individuals With Dementia Living In Long-Term Care, Angela Conti Dec 2006

Meaningful Activities For Individuals With Dementia Living In Long-Term Care, Angela Conti

All Theses

Among older adults with Alzheimer`s disease, 61% to 88% experience problematic passivity (Kolanowski, 1995), which has been linked to a loss of functional abilities (Colling, 1999). In order to prevent this functional decline, social isolation, and development of problematic passivity guidelines can be deduced from the Need-driven Dementia-compromised Behavior (NDB) model for identifying the causes of passive behavior, which can be addressed when designing specialized therapeutic recreation programs.
The purpose of this study was to determine the efficacy of meaningful activities compared to traditional nursing home activities on the level of alert engagement among individuals with dementia living in a …

Phylogeny Of Family Limnephilidae (Insecta: Trichoptera) With Emphasis On Tribe Limnephilini (Subfamily Limnephilinae), Tatyana Vshivkova

All Dissertations

Morphological characters of adults and immature stages of Limnephilidae were analyzed with modern phylogenetic techniques, including traditionally used characters and some that have been poorly investigated or never studied. For the first time, monophyly is inferred for the following nominotypical taxa: superfamily Limnephiloidea, family Limnephilidae, subfamily Limnephilinae, tribe Limnephilini, and Limnephilus sensu stricto. Some other higher taxa are distinguished based on high bootstrap support, unreversed synapomorphies, and/or topography, including a new family-group category for Trichoptera, 'Branch,' more inclusive than the family category and less inclusive than the superfamily category. These new taxa in Limnephiloidea are as follows: Brachycentrida New Branch …
