Health Beliefs And Socio-Cultural Factors That Predict Cervical Cancer Screening Behaviors Among Hispanic Women In Seven Cities In The Upstate Of South Carolina, Arelis Moore De Peralta

All Dissertations

Cervical cancer is one of the most common reproductive cancers among women in the United States. The incidence and mortality rates of cervical cancer among Hispanic women in the U.S. are almost two times higher than non-Hispanic Whites. Cervical cancer screening is associated with early cervical cancer detection and, thus, with reductions in cancer morbidity and mortality. In Hispanic populations, where cancer rates are disproportionately high, it is important to conduct research that accounts for the influence of culture in health-seeking behaviors. The purpose of this study was to use the Health Belief Model (HBM) as a theoretical framework to …

Characterizing Mechanical Heterogeneity In Cardiovascular Cells, Sandra Deitch Dec 2011

Characterizing Mechanical Heterogeneity In Cardiovascular Cells, Sandra Deitch

All Dissertations

Most tissue-level mechanical models assume homogeneous mechanical properties within a single cell type. However, measurements of cellular mechanical properties show large variability in whole-cell mechanical properties between cells from a single population. This heterogeneity has been observed in many cell populations and with several measurement techniques but the sources are not yet fully understood. Cell mechanical properties are directly related to the composition and organization of the cytoskeleton, which is physically coupled to neighboring cells through adherens junctions and to underlying matrix scaffolds through focal adhesion complexes. As such, we believe that this high level of heterogeneity can be attributed …

Evaluation Of Bioaugmentation Strategies To Treat High Concentrations Of Chloroform And Carbon Tetrachloride, Han Wang Dec 2011

Evaluation Of Bioaugmentation Strategies To Treat High Concentrations Of Chloroform And Carbon Tetrachloride, Han Wang

All Theses

Halogenated methanes, including carbon tetrachloride (CT) and chloroform (CF), are significant groundwater contaminants. Options for bioremediation of high concentrations are limited. Previous studies have shown that an enrichment culture (designated DHM-1) that grows on corn syrup has the potential for use in bioaugmentation. DHM-1 cometabolically biotransforms high concentrations of CT and CF to nontoxic end products (mainly CO, CO2, and organic acids) in the presence of vitamin B12 (approximately 3% of chlorinated methanes on a molar basis). Sulfide is also required by this culture to function properly. However, insufficient data are available on its performance under field conditions. Also, it …

Robust Design And Monitoring Tools For Sustainable And Resilient Structural Design And Infrastructure Management, Sarah Dalton Dec 2011

Robust Design And Monitoring Tools For Sustainable And Resilient Structural Design And Infrastructure Management, Sarah Dalton

All Theses

Structural systems are subject to inherent uncertainties due to the variability in many hard-to-control `noise factors' that include but are not limited to external loads, material properties, and construction workmanship. Two design methodologies have been widely accepted in the practicing engineering realm to manage the variability associated with operational structures: Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD). These traditional approaches explicitly recognize the presence of uncertainty; however, they do not take robustness against this uncertainty into consideration. Overlooking this robustness against uncertainty in the structural design process has two drawbacks. First, the design may not satisfy …

Effects Of Larval Exposure To Bacterial Species In Three Genera On Life History Traits And Oviposition Behavior In The Southern House Mosquito, Culex Quinquefasciatus, Jonathan Gravgaard

All Theses

The biofilm is the most common niche for microorganisms living in aquatic environments. Forming a biofilm provides the means to resist shear forces, adverse osmolarity, chemical agents, and other environmental stressors. Biofilms also provide a major food source for aquatic arthropods like mosquito larvae. Culex quinquefasciatus larvae are found in freshwater pools with high organic content, and have the ability to graze on bacterial biofilms. To study how C. quinquefasciatus mosquitoes interact with bacteria in their environment I developed an experimental system that allows mosquito larvae to freely graze on bacteria in either the planktonic or biofilm state. The efficacy …

An Analysis Of Managerial Retention Decisions Using Major League Baseball, William Ward Dec 2011

An Analysis Of Managerial Retention Decisions Using Major League Baseball, William Ward

All Theses

Major League Baseball managers are often blamed for the poor performance of a baseball team. In the past two years alone, there have been eight midseason managerial firings and six postseason managerial firings. While this number may seem high, these numbers have actually been consistent with probabilities of managerial retention since 1930, when baseball was still in the early stages of its development as a professional sport. In the following study, I examine the factors that are taken into account during these managerial firing decisions and what conditions are present when changes do take place. Using Major League Baseball managerial …

Electrical Coupling Between Micropatterned Cardiomyocytes And Stem Cells, Zhen Ma Dec 2011

Electrical Coupling Between Micropatterned Cardiomyocytes And Stem Cells, Zhen Ma

All Dissertations

To understand how stem cells functionally couple with native cardiomyocytes is crucial for cell-based therapies to restore the loss of cardiomyocytes that occurs during heart infarction and other cardiac diseases. Due to the complexity of the in vivo environment, our knowledge of cell coupling is heavily dependent on cell-culture models. However, conventional in vitro studies involve undefined cell shapes and random length of cell-cell contacts in addition to the presence of multiple homotypic and heterotypic contacts between interacting cells. Thus, it has not been feasible to study electrical coupling corresponding to isolated specific types of cell contact modes.

Development Of A Dynamic In Vitro Model Of A Stented Blood Vessel To Evaluate The Effects Of Stent Strut Material Selection And Surface Coating On Smooth Muscle Cell Response, Bradley Winn

All Dissertations

Cardiovascular disease is the leading cause of mortality in The United States and Europe, accounting for approximately half of all deaths. The most common form of cardiovascular disease is atherosclerosis, which is characterized by the formation of fatty atheromatous plaques that can grow to occlude the vessel lumen, thus causing ischemia distal to the occlusion. This is commonly treated using balloon angioplasty, which is usually done in conjunction with the deployment of a stent. Stent deployment helps hold the vessel open following the local injury caused by balloon inflation and prevents elastic recoil and subsequent negative remodeling. Stenting has been …

Light-Emitting Nanocomposites And Novel Amorphous Polymers For Optical Applications, Kyle Gipson Dec 2011

Light-Emitting Nanocomposites And Novel Amorphous Polymers For Optical Applications, Kyle Gipson

All Dissertations

Polymeric optical materials generally are comprised of amorphous polymers that are transparent in at visible wavelengths but exhibit strong absorption bands in the near-infrared making them less useful for many optical applications. Attenuation, which is the absorption per unit length, largely results from the high vibrational energy associated with carbon-hydrogen bonds contained in the polymer backbone. Attenuation can be mitigated by optical amplification utilizing light emitting additives. Investigated in this dissertation are synthesis techniques for the fabrication of light-emitting polymer nanocomposites and their resultant thermal and rheological characteristics for potential use as polymer optical fibers or films.
Inorganic nanocrystals doped …
