Behavior In Air Leakage And Recirculation Under The Influence Of Booster Fans, Koziba Feledi

Masters Theses

"A booster fan is an underground mechanical ventilation equipment installed in series with a main surface fan that is used to boost the air pressure provided by the surface main fan passing through it. As mining continues to expand and go deeper, the need for improved and efficient ventilation increases. This has led to the use of booster fans and other auxiliary ventilation devices in underground mines. Research defining how system leakage and recirculation are affected by booster fans; describing how system leakage and recirculation are affected by the location, placement, and amount of air pressure from the booster fans; …

Ecology Of A Declining Great Plains Fish, Fundulus Sciadicus, In The Missouri Ozarks, Gregory Travis Thompson

Masters Theses

"Anthropogenic habitat disturbances are of growing concern due to their impacts on native biota, especially in freshwater ecosystems. Damming, channelization, urbanization, wetland draining, and non-native fish introductions all play large roles in habitat homogeneity, fragmentation, and species competition. This has negative effects on native fish and invertebrate species. In the Midwestern United States, the plains topminnow (Fundulus sciadicus) has been declining across its range, to the point of becoming a species of special concern in Missouri. This is possibly due to a combination of the above anthropogenic habitat disturbances. To better understand the ecology of the plains topminnow …

Critical Editions And Comparative Analysis Of Three Representative Wind Band Works From The French Revolution, Adam Gary Kehl

Theses and Dissertations

The French Revolution witnessed the greatest output of music for wind band before the twentieth century. The importance of wind bands and wind repertoire grew for several reasons including, most notably, their participation in government sponsored outdoor national festivals. Festival celebrations were large gatherings in which wind band music was a central component. The French National Guard Band was the dominant musical ensemble in revolutionary France; its leaders, François Gossec, Bernard Sarrette, and Charles-Simon Catel, were among France's most important musical figures between 1789-1799. These men, in combination with music schools established in Paris during the Revolution, helped shaped the …

Clarissa's Suffering: Theorizing Sympathy And Physical Pain In The Eighteenth Century, Audrey Hungerpiller

Theses and Dissertations

This thesis examines theories of pain in the eighteenth century, and what it meant to sympathize with the pain of another. I begin briefly with the theories of Descartes and his adherents before focusing on David Hartley and John Locke. Physicians and natural philosophers of the period understood pain as a pure mechanism of the nervous system, confined to the tubelike fibers that run through the body. Naturally everyone feels pain by some means, whether illness or injury, so men ought to be able to sympathize with the afflictions of others. Yet, according to Adam Smith in The Theory of …

Anthropogenic Ecological Impacts Of 17th And 18th Century Chickasaw Through A Study Of Faunal Remains, Marybeth Harte

Theses and Dissertations

A diachronic analysis of five faunal assemblages from Chickasaw sites is carried out to evaluate their anthropogenic ecological impacts during the colonial time period (A.D. 1650-1750). Change in faunal exploitation, diversity measures and disturbance taxa frequencies are analyzed to gauge these impacts. A comparison with late Mississippian period faunal use provides a benchmark to examine how shifts in the cultural system initiated new ecological impacts. Results from the faunal analysis are also compared with reports of faunal utilization and landscape management practices in the historical record. These reports provide a basis for assessing change in prey preferences according to the …

School Racial Climate And The Academic Achievement Of African American High School Students: The Mediating Role Of School Engagement, Charity Brown Griffin

Theses and Dissertations

African American students in K-12 education experience pervasive disparities in academic outcomes across all areas of the schooling experience. In order to understand the factors that promote academic achievement among individuals who face adversity, researchers have sought to examine how school environmental factors hold influence over students' academic adjustment. Drawing from an integrative model of development for ethnic minority children and a process model of engagement, this investigation explored whether three dimensions of school engagement, behavioral, emotional and cognitive, mediated relationships between school racial climate and academic performance and educational aspirations. These relationships were explored in a sample of 139 …

Identifying Identity: An Archaeological Investigation Of The Intersection Of Place And Identity At An African American Lowcountry Site, Katherine Elisabeth Goldberg

Theses and Dissertations

African and African American communities have faced pressures of marginalization and racism in the South Carolina Lowcountry since their arrival with Europeans in the seventeenth century. These pressures have been felt physically, socially, economically, politically, and even academically, through misrepresentations in historical portrayals. The field of historic archaeology is uniquely situated with access to informative sources from both the past and the present, and as such exhibits great potential in taking strides to replace the limiting presentation of a static and homogenous single African American culture with views that instead emphasize a focus on unique cultures and identities. This thesis …

Non-Native Speaker Attentional Capacity And The Processing Of English Phrasal Verb Constructions, Aubrey Dillard

Theses and Dissertations

The effect of syntactic and semantic complexity on attention and processing in second language acquisition (SLA) has long been of interest to both practitioners and researchers of SLA. Theoretical models of attention in SLA (Schmidt 1990, Tomlin and Villa 1994, Robinson 1995) have spurred a great deal of empirical research in the field, and VanPatten's (1994, 2004, 2007) work on the effect of attention to form and meaning on comprehension of input has been very influential in the field. From a language processing viewpoint, Clahsen and Felser (2006, 2009) have hypothesized that the different ways in which native and nonnative …

An Evolutionary Perspective On Infectious And Chronic Disease, John Eberth

Theses and Dissertations

The integration of evolutionary biology with traditional medicine can elucidate novel mechanisms of contemporary disease. Whereas the goal of traditional medicine is to treat and cure the proximate causes, evolutionary biology aims to understand the driving forces behind why humans are susceptible to disease. To form the basis of this hypothesis we postulate that modern man's current genetic information was programmed at a time, and in an environment, that is not relevant to today's human populations. The discordance between these genes of our ancestors and the environment of contemporary humans is thought to be a major reason for the increase …

The Charleston "School Of Slavery": Race, Religion, And Community In The Capital Of Southern Civilization, Eric Rose

Theses and Dissertations

This dissertation explores the interracial religious communities of antebellum South Carolina to highlight patterns of racial consciousness and nation-building and demonstrate that the southern path to modernity was much closer to that of their northern contemporaries than previously recognized. The ready-made system of human classification inherent in racial slavery did not insulate southerners from the modern impulses that transfigured northern racial relations; instead, this dissertation argues that Carolinians white and black, free and slave, participated in a discourse of religious modernization that redirected the potentially destabilizing social implications of evangelicalism and progress into an idealized community structure that served the …

Understanding Hydrothermal Carbonization Of Mixed Feedstocks For Waste Conversion, Xiaowei Lu

Theses and Dissertations

Hydrothermal carbonization (HTC) is an environmentally beneficial means to convert waste materials to value-added solid and liquid products with minimal greenhouse gas emission. Research is lacking on understanding the influence of critical process conditions on product formation and environmental implication associated with HTC of waste streams. This work was conducted to determine how reaction conditions and heterogeneous compound mixtures (representative of municipal wastes) influence hydrothermal carbonization processes. The specific experiments include: (1) determine how carbonization product properties are manipulated by controlling feedstock composition, process conditions, and catalyst addition; (2) determine if carbonization of heterogeneous mixtures follows similar pathways as that …

Discovery And Characterization Of Multi-Target Directed Ligands As Inhibitors Of Amyloid-Β Aggregation And Regulators Of Alzheimer's Disease, Jui-Heng Tseng

Theses and Dissertations

Alzheimer's disease (AD) is the most common neurodegenerative disease in the world. As the disease advances, symptoms include confusion, language skill breakdown, and long term memory loss - and culminate in death. Existing therapies for AD provide symptomatic benefits but cannot halt or slow the disease pathogenesis.

Increasing evidence reveals the multi-factorial nature of AD. Numerous factors, including amyloid-β (Aβ) aggregation, calcium homeostasis dysregulation, and oxidative stress, contribute to disease development and interplay with each other. Therefore, multi-target directed ligands (MTDLs) may present an effective AD treatment. Among all factors, Aβ aggregation is suggested to play the most crucial role. …

Antibiotic Usage In Relation To Resistant Bacterial Infections And Liver And Kidney Cancer Outcomes In South Carolina, Prea Thathiah

Theses and Dissertations

Antibiotics are one of the most beneficial discoveries in medicine and public health. However, the use, overuse, and misuse of these drugs have led to increases in antibiotic resistant bacterial infections (ARI). Furthermore, previous epidemiological studies have linked antibiotic use to breast cancer, but these studies have not included effects on metabolic organs, such as the liver and kidneys. This dissertation investigates the role of antibiotic use in infections and liver and kidney cancers in the state of South Carolina. Using ecological study methods and Poisson regression to determine relative risk ratios, it was found that antibiotic use is a …

By examining my journey from an undergraduate design student, to graduate design student, and finally as an intern with William Ivey Long, I will analyze my work as a Costume Designer.

Mitochondrial Replication From Embryogenesis To Early Adulthood, In Dui Species, Mytilus Galloprovincialis, Ellen Blenn Richardson

Theses and Dissertations

Eukaryotes typically inherit mitochondria strictly maternally. There are however a group of bivalve molluscs that inherit different mitochondrial genomes from each parent. The paternally inherited mtDNA (M-type) is localized to, and dominates over the maternally inherited mtDNA (F-type) in the gonads of the male offspring, but is not normally retained in any tissue of the female offspring. This process is termed Double Uniparental Inheritance (DUI). Using quantitative PCR (qPCR), this study examines mtDNA replication compared to total DNA replication through embryonic stages of development and into early adulthood of the DUI species, Mytilus galloprovincialis. Results indicate that up through the …

The Role Of Microrna In Staphylococcal Enterotoxin B-Induced Inflammation And Acute Lung Injury, Roshni Rao

Theses and Dissertations

Staphylococcal enterotoxin B (SEB) is a potent activator of the Vβ8+T-cells leading to the proliferation of nearly 30% of the T-cell pool. As a consequence, excessive amounts of cytokine mediators are released leading to extensive tissue damage and sometimes toxic shock and death. Due to the ease with which SEB can be aerosolized anddisseminated, it is considered a biological weapon. In the current study, we investigated the pro-inflammatory effects of SEB in two mouse models of acute inflammatory lung injury. Specifically, while inflammatory cues are known to elicit changes in key transcriptional factors and gene expression, we explored for the …

Characterization Of The Hippocampal Acetylcholine System In A Rodent Model Of Fetal Alcohol Syndrome, Amy Elizabeth Perkins

Theses and Dissertations

Fetal alcohol spectrum disorders (FASD) are a major public health concern, as it is estimated that 2-5% of children are exposed to alcohol at some point during prenatal development. FASD have been shown to cause damage to multiple brain regions, but research shows that the hippocampus is especially sensitive to alcohol exposure. This damage to the hippocampus explains, in part, deficits in learning and memory that are hallmark symptoms of FASD. The acetylcholine neurotransmitter system plays a major role in learning and memory, and the hippocampus is one of its main targets. This experiment used a rodent model of Fetal …

Parental Mediation Of Adolescent Movie Viewing, Larry James Webster Jr.

Theses and Dissertations

Parental mediation of media use by children has been studied extensively as it applies to television and children 12 years old and younger. This study expands the scope of Parental Mediation Theory by applying it to adolescents (age 13-17 years old) and movie viewing. The results of this study show overall parental mediation of adolescent movie viewing is negatively associated with the age of the child. The results show that among parents who mediate movie viewing, restrictive, instructive and social co-viewing mediation strategies are negatively correlated with the age of the adolescent. Third Person Effect is also examined as parental …

Stimulus Modality And The Rotational Error: An Examination Of The Various Reorientation Accounts In Humans Using A 3d Virtual Environment, Samuel P. Police

College of Graduate Studies: Theses & Dissertations

Reorientation occurs when an organism enters a novel environment and utilizes cues within said environment to get its bearings. Though reorientation occurs, little is known about which cues are utilized to reorient and the mechanism underlying this reorientation process. Three competing accounts of how the reorientation process occurs were presented and discussed in terms of which cues are predicted to be utilized in reorientation: the geometric module, the associative strength model, and the adaptive-combination view. In the present experiment, human participants were trained in an immersive, 3D virtual environment trapezoid to local a goal location in the presence of either …

Temporal Patterns Of Aquatic Macroinvertebrate Communities And Organic Matter Standing Stock Availability In A Coastal Floodplain (Altamaha River, Georgia), Erica L. Johnson

College of Graduate Studies: Theses & Dissertations

River floodplain habitats of the Southeastern United States are sites of high biological productivity that rely on a predictable flooding event as a keystone process. This study took place in a river-floodplain area of the Altamaha River, an unimpounded large-order river in the Coastal Plains region of the US. This study aims to investigate how aquatic macroinvertebrate communities changed over the course of the annual flood pulse. I predicted that the communities would be different and that the differences would be driven by hydrology at the main stem and organic matter standing stock availability. I took quantitative samples of benthic …

Pausing Of Children During Signaled And Unsignaled Transitions, Apral P. Foreman

Graduate Theses, Dissertations, and Problem Reports (ETD)

We evaluated effects of signaled and unsignaled transitions between reinforcement schedules on pausing and run rates of academic responding and rate and duration of problem behavior for four children who engaged in chronic and severe problem behavior. Children completed an academic task on a computer program to earn access to brief video clips. Lean (more responses and short videos) and rich (few responses and long videos) reinforcement schedules were alternated within each session, creating four transition types: lean-to-lean, lean-to-rich, rich-to-rich, and rich-to-lean. Pausing was measured as the latency to initiate the first response of a reinforcement schedule. Run rates were …
