Metalloporphyrin Catalyzed Degradation Of Pce: Effects Of Reductants, Buffers And Cosolvent Concentration, Sowmya Suryanarayanan Dec 2007

Metalloporphyrin Catalyzed Degradation Of Pce: Effects Of Reductants, Buffers And Cosolvent Concentration, Sowmya Suryanarayanan

All Theses

Reductive dechlorination of chlorinated organic contaminants using metalloporphyrins as catalysts may be an effective approach to treat widespread contamination. However, most previous studies have examined water-soluble rather than insoluble metalloporphyrins despite the fact that the latter category makes up the largest fraction found in nature. Recent studies have shown that addition of different cosolvents to water can activate otherwise non-reactive metalloporphyrin catalysts and facilitate the reduction of tetrachloroethylene (PCE), presumably by the mere process of making the otherwise insoluble metalloporphyrins dissolve in solution. Therefore, solubility has been advanced as a key factor in the ability of metalloporphyrins to catalyze organic …

Overwhelming Systems, Meghan Oconnor Dec 2007

Overwhelming Systems, Meghan Oconnor

All Theses

My work portrays my own social and cultural desires, fears, and experiences. I employ a narrative format that shows childhood cartoon influences to attract viewers and visual complexity to sustain them. I depict fear, tension, struggle, and isolation to reveal deception, which stems from a response to structures of power. It is a representation, a questioning, and/ or a critique of the state of today's human nature and subsequent condition. I employ images of animals as a stand-in for the human figure, feeling or persona. Mechanical devices are metaphors of harmful systems of culture or power. The illusion of transparency …

Neochetina Species And Arthropod Communities In Water-Hyacinth Rafts In South Carolina, Benjamin Powell Dec 2007

Neochetina Species And Arthropod Communities In Water-Hyacinth Rafts In South Carolina, Benjamin Powell

All Theses

Arthropod communities inhabiting feral water-hyacinth rafts were surveyed monthly in South Carolina's Coastal Plain from March 2005 through February 2006. Special attention was given to the chevroned waterhyacinth weevil [Neochetina bruchi (Hustache)], the mottled waterhyacinth weevil [N. eichhorniae (Warner)] (both Coleoptera: Curculionidae), and the waterhyacinth moth [Niphograpta albiguttalis (Warren)] (Lepidoptera: Crambidae), which were imported into North America to control water-hyacinth. Communities of arthropods are compared among sites, flow regimes (lentic, lotic, and tidal), and months of the year. The arthropod communities in waterhyacinth rafts in South Carolina are more diverse than previously reported. Rafts in each of …

All Dissertations

The effect of clay content, homogenization RPM, and pH on the mechanical and barrier properties of fish gelatin/nanoclay composite films was investigated. The addition of clay increased the tensile strength (TS) from 30.31±2.37 MPa to 40.71±3.30 MPa. The nanoclay composite film had improved oxygen and water barrier properties when compared to neat fish gelatin film. Oxygen permeability decreased from 0.0004028±0.0000007 gm/m2dayatm to 0.0001144±0.0000162 gm/m2dayatm and the water vapor permeability decreased from 0.0312±0.0016 ngm/m2sPa to 0.0081±0.0001 ngm/m2sPa.

Analysis Of Hg And Stable Isotope Concentrations In Bald Eagle Feathers From The Great Lakes And Voyageurs National Park, Minnesota, Jennifer Thomsen

All Theses

Bald eagles (Haliaeetus leucocephalus) feed on a variety of aquatic and terrestrial wildlife. As top predators in their food chain, they may accumulate harmful concentrations of pollutants such as mercury, which can have detrimental effects on populations of this species. The stable isotope composition of feathers provides useful information about the food resources assimilated by bald eagles. The connection between mercury, (Hg), concentration and stable isotope concentration ( 13C and 15N) of feathers were measured to better understand the potential sources and pathways of Hg uptake by bald eagles living in the Great Lakes region of Michigan and Voyageurs National …

Cosolvent Effects On The Reductive Dechlorination Of Tetrachloroethylene Catalyzed By Iron Tetraphenyl Porphyrin Chloride, Lavanya Ramasubramanian Dec 2007

Cosolvent Effects On The Reductive Dechlorination Of Tetrachloroethylene Catalyzed By Iron Tetraphenyl Porphyrin Chloride, Lavanya Ramasubramanian

All Theses

Abiotic electron transfer mediated reductive dechlorination reactions have been studied extensively in the past decade. Porphyrins and metalloporphyrins are common electron transfer mediators used. Past studies have shown that some metalloporphyrins play a key role in increasing the rate of reaction in the presence of cosolvents. There have also been suggestions that organic cosolvents enhance the rate of reduction by increasing the solubility of metalloporphyrins.
The primary objective of this project was to examine the effect of cosolvents on the metalloporphyrin-catalyzed reductive dechlorination of tetrachloroethylene (PCE). Subsequently, experiments were also conducted to test the hypothesis that metalloporphyrin solubility is linked …

Rendering Principal Direction Contour Lines With Oriented Textures, Kelly Gallagher Dec 2007

Rendering Principal Direction Contour Lines With Oriented Textures, Kelly Gallagher

All Theses

In this paper we explore the use of contour lines in computer graphics as a means of conveying shape to the end-user. Contour lines provide an alternative to traditional realistic rendering styles and may even provide a more appropriate visualization for certain situations. For our images, contour line orientation is established in accordance with principal curvature directions.
We present a method for rendering a texture, oriented in the principal curvature direction, across a traditionally-modeled geometric surface that effectively forms suggestive contour lines to enhance the visualization of that surface. We further extend the method to create animated contour textures, wherein …

The Firm Size, Farm Size, And Transaction Costs: The Case Of Hazelnut Farms In Turkey, Ibrahim Demir Dec 2007

The Firm Size, Farm Size, And Transaction Costs: The Case Of Hazelnut Farms In Turkey, Ibrahim Demir

All Dissertations

ABSTRACT This study analyzes the determinants of the size of the hazelnut farms in Turkey within the framework of the theory of firm and transaction costs. This study argues that, for a farm production function, land is a complex input with many transaction cost-increasing interactions with nature. Natural effects, such as land slope and variation in the weather conditions, can increase transaction costs. Transaction costs are the costs of using the inputs necessary for production. This study utilizes two separate data sets in order to test if the predicted relationship between transaction costs and farm size holds. The first data …

A Breakdown In Boundaries: As Explored Through Abjection And The Language Of Abstract Art, Mary Hanley Dec 2007

A Breakdown In Boundaries: As Explored Through Abjection And The Language Of Abstract Art, Mary Hanley

All Theses

ABSTRACT
My work places emphasis on the anxiety and allure felt at the possibility of ingesting an object belonging to or displaced from the body through the language of abstract art. It links the fears and fascinations felt in situations of perceived abnormality and bodily aggression, to the objectification, or conversely abjection, of objects through images. I investigate a collapse in division between what the perceived identity of a thing or person is, and what it is not.
Each painting rejects an ideal of beauty as portrayed through stability, clarity, and compartmentalization, and embraces beauty as the interconnectedness of opposing …

Provisioning And Prey Quality In Brown Pelicans (Pelecanus Occidentalis) In Charleston Harbor, South Carolina, Elena Sachs Dec 2007

Provisioning And Prey Quality In Brown Pelicans (Pelecanus Occidentalis) In Charleston Harbor, South Carolina, Elena Sachs

All Theses

I examined parent and nestling behavior during early chick rearing in Brown Pelicans (Pelecanus occidentalis) nesting at a colony in Charleston Harbor, South Carolina during the 2006 breeding season. There were significant differences in the frequency of feeding, attendance, and chick aggression according to chick age, although the pattern differed among behaviors. The rate of adult feeding, chick feeding and adult attendance all decreased with chick age while chick aggressive behavior peaked when chicks were ca. 21 d post-hatch. I found that nests with at least one juvenile parent had a lower average clutch size, hatch rate, and number of …

Characterization Of The Anti-Angiogenic Properties Of Kdr-Ig4-7 And Its Variants As Potential Anti-Cancer Therapeutics, Jang Pyo Park Dec 2007

Characterization Of The Anti-Angiogenic Properties Of Kdr-Ig4-7 And Its Variants As Potential Anti-Cancer Therapeutics, Jang Pyo Park

All Dissertations

Beginning with the development of an embryo and throughout one's adult life angiogenesis plays an essential role for organ growth and repair. The balancing of pro-angiogenic factors to anti-angiogenic factors is what regulates the process of angiogenesis. When this balance is disrupted in one direction or the other, numerous disorders can occur including ocular and inflammatory diseases and, in particular, tumor growth and metastasis. Therefore, inhibition of angiogenesis has become an effective therapy for arresting the growth of tumors.
A key regulator of angiogenesis involves vascular endothelial growth factor (VEGF) and its receptor, VEGFR-2 (KDR). The binding of VEGF to …

Phylogeny And Classification Of Hydropsychidae Subfamilies And Genera Of The World (Insecta: Trichoptera), Christy Geraci Dec 2007

Phylogeny And Classification Of Hydropsychidae Subfamilies And Genera Of The World (Insecta: Trichoptera), Christy Geraci

All Dissertations

The family Hydropsychidae is nearly ubiquitous in streams and rivers, with over 1600 described species worldwide. Hydropsychidae is ecologically important and its larvae play key roles as indicators of water quality. Conflicting morphological characters have obscured the evolutionary history of the subfamilies, and the wide diversity of phallic morphology among Hydropsyche sensu lato species has created unstable classification systems that have been disputed among authors. My research used five nuclear ribosomal and mitochondrial COI fragments to infer a molecular phylogeny for Hydropsychidae subfamilies and genera, focusing particularly on the Hydropsychinae and the Hydropsyche sensu lato lineage. The monophyly of four …

Comparison Of Compost Tea And Biological Fungicides For Control Of Early Blight In Organic Heirloom Tomato Production, Richard Kouyoumjian Dec 2007

Comparison Of Compost Tea And Biological Fungicides For Control Of Early Blight In Organic Heirloom Tomato Production, Richard Kouyoumjian

All Theses

The efficacy of compost tea was evaluated and compared alone and in combination with two biofungicides Serenade Max and Sonata for control of early blight caused by the fungal pathogen Alternaria tomatophila on tomato Solanum lycopersicum (L), heirloom cultivar `Cherokee Purple'. Results of field experiments over two growing seasons indicated that compost tea provided a low level of protection against early blight. The results were variable; most likely due to dry conditions and the presence of bacterial wilt the first year and tomato spotted wilt virus the second year. In both 2006 and 2007 field trials compost tea was not …

Enhancing The Ability Of Panicum Virgatum To Survive Flooding And Its Effects On Soil Activity When Used For Lakeshore Stabilization, Lee Edwards

All Dissertations

Reservoirs in upstate South Carolina are subject to erosion and vegetation has been placed to help stabilize banks, but soils are nutrient-poor and have high bulk densities. Panicum virgatum L. (switchgrass) has been planted in several sites, and it is hypothesized that over time, changes in microbial activity and soil quality will occur in response to the planting. As vegetated sites aged, acid phosphomonoesterase, nitrate reductase, and dehydrogenase activity increased. Low values of nitrogen fixation and substrate-induced respiration were measured at all sites with no statistical differences between sites. Fatty acids indicative of Gram negative bacteria were found in vegetated …

Evaluation Of Human Prolactin, Its Antagonist, And Antagonist-Based Fusion Proteins As Chemopreventative And Therapeutic Agents, Seth Tomblyn Dec 2007

Evaluation Of Human Prolactin, Its Antagonist, And Antagonist-Based Fusion Proteins As Chemopreventative And Therapeutic Agents, Seth Tomblyn

All Dissertations

Cancer is a collection of diseases with many different manifestations and is the second leading cause of death in the United States. Breast cancer accounts for nearly one third of cancer diagnosis in women. Prolactin (PRL) functions as a lactogen and as a mammary gland differentiation factor. PRL acts in an autocrine/paracrine manner within the mammary gland and in breast tumors which implies PRL may be involved in breast cancer progression. This is corroborated by the PRLR over-expression in breast cancer cells lines and the majority of patient biopsies. These reasons make PRL and PRLR attractive targets for breast cancer …

Diversity And Abundance Of Ants At Forest Edges , Eric Paysen Dec 2007

Diversity And Abundance Of Ants At Forest Edges , Eric Paysen

All Dissertations

Fragmented habitats are a common result of human activities that involve the clearing of native vegetation for various land uses. Habitat fragmentation has two primary and inseparable components: habitat loss and insularization. Landscape-level connectivity in fragmented habitats is diminished for many species, and edge characteristics become more important as the edge-to-interior ratio increases. The study of the effects of edges on biodiversity has compelled ecologists to study them for over a century and has influenced the design and management of natural preserves. Invasion of habitats by non-native species is a phenomenon that coincides with the increased human activity typical of …
