Use Of Polyhydroxyalkanoates For Denitrification In Recirculating Aquaculture Systems, Maria Teresa Gutierrez-Wing Jan 2006

Use Of Polyhydroxyalkanoates For Denitrification In Recirculating Aquaculture Systems, Maria Teresa Gutierrez-Wing

LSU Doctoral Dissertations

Increasing demand of aquacultural products is driving the industry toward more intensive culture practices. Aquacultural operations are constrained by limitations on the availability high quality waters and regulatory pressures on the discharges. Recirculating systems can address these issues by reducing the amount of water required in the operation. Closed systems are especially suited where biosecurity is important. In closed systems, nitrate accumulates, limiting the time the water can be reused. In marine inland systems, water reuse reduces the cost of salt for make up water. To increase the water reuse time, some form of nitrate removal process must be incorporated …

Jack Kerouac's Spontaneous Prose: A Performance Genealogy Of The Fiction, Justin Thomas Trudeau Jan 2006

Jack Kerouac's Spontaneous Prose: A Performance Genealogy Of The Fiction, Justin Thomas Trudeau

LSU Doctoral Dissertations

This study analyzes Jack Kerouac’s writing method of spontaneous prose and articulates how the method can be understood as performative writing. Kerouac’s “Essentials of Spontaneous Prose,” On the Road, Visions of Cody, and Doctor Sax are explored to evaluate both the successes and failures of the author’s attempts to break literary boundaries and create a new writing method based upon spontaneous tenets. These three novels, which were written in succession from 1950 to 1953 when Kerouac was in his most productive period, represent both the emergence and dissent of the author’s use of performative writing. To explicate the cultural genesis …

Syntheses And Biological Evaluation Of Water Soluble Carboranylporphyrins For Application In Boron Neutron Capture Therapy, Vijay Gottumukkala Jan 2006

Syntheses And Biological Evaluation Of Water Soluble Carboranylporphyrins For Application In Boron Neutron Capture Therapy, Vijay Gottumukkala

LSU Doctoral Dissertations

The goal of the research presented in this dissertation is to develop novel water soluble carboranylporphyrins that can deliver therapeutic dosage of boron specifically to tumors for application in boron neutron capture therapy. In order to accomplish this goal novel water soluble tetra(nido-carboranyl)porphyrin and the octa(nido-carboranyl)porphyrin with high boron contents are synthesized by the condensation of the carborane substituted benzaldehyde with the pyrrole under acidic conditions. These porphyrins are made water soluble by the deboronation of the closo-carboranes to afford the corresponding amphiphilic nido-carborane cages. The low cytotoxicity, high cellular uptake and intracellular localization of these carboranylporphyrins in tumor cells …

Measuring The Degree Of Market Power In The Export Demand For Soybean Complex, Dwi Susanto Jan 2006

Measuring The Degree Of Market Power In The Export Demand For Soybean Complex, Dwi Susanto

LSU Doctoral Dissertations

Previous studies on market power hypothesis strictly assumed that the data used in the analysis were a stationary process. This assumption has been argued that not all time series exhibit a stationary process such that conventional asymptotic theory cannot be applied. This study adopts the “New Empirical Industrial Organization” (NEIO) approach developed by Bresnahan (1982) and Lau (1982) to measure the degree of market power in the export market for soybean complex. The non-stationary properties of the data were accommodated by formulating the model in an error correction framework (ECM) developed by Bårdsen (1989) and applied by Steen and Salvanes …

Effects Of Diesel-Fuel And Copper Contaminants On Benthic Microalgae, Soraya Silva Jan 2006

Effects Of Diesel-Fuel And Copper Contaminants On Benthic Microalgae, Soraya Silva

LSU Doctoral Dissertations

Salt marshes are dynamic, highly productive habitats and serve as nursery grounds for many commercially and economically important species. Benthic microalgae (BMA) are considered an important food source for benthos and provide the principal source of nutrition that fuels secondary production. Estuarine sediments around the world are a repository for many contaminants from anthropogenic sources. In particular, hydrocarbons and metals are ubiquitous contaminants in coastal systems. The primary goal of this study was to study the effects of diesel fuel and copper, alone and in combination, on the BMA assemblage from a coastal salt marsh. To achieve this objective, salt …

Substrate Utilization In Skeletal Muscle And Adipose Tissue, Lauren M. Sparks Jan 2006

Substrate Utilization In Skeletal Muscle And Adipose Tissue, Lauren M. Sparks

LSU Doctoral Dissertations

Obesity and Type 2 diabetes are associated with high fat diet (HFD), reduced mitochondrial mass and function and insulin resistance as characterized by glucose disposal and relative to body fatness. We hypothesized that (a) HFD affects expression of genes involved in mitochondrial biogenesis and function, (b) carbohydrate metabolism and storage is under transcriptional control and (c) both overall fatness and characteristics of adipose tissue influence the interplay between free fatty acids (FFAs) and insulin-stimulated glucose disposal. To test hypotheses “a” and “b”, we fed 10 insulin-sensitive males an isoenergetic HFD for 3 days with muscle biopsies before and after intervention. …

Reinscribing The Revolution: Genre And The Problem Of National History In Early American Historical Novels, Joseph John Letter Jan 2006

Reinscribing The Revolution: Genre And The Problem Of National History In Early American Historical Novels, Joseph John Letter

LSU Doctoral Dissertations

This dissertation examines nine early historical novels of the Revolution that recover an important yet largely forgotten archive of American cultural history. In the years following the War of 1812 writers from the Revolution’s successor generation reinscribed the history of national origins through narratives of the Revolution that address issues left unresolved by the Revolutionary War and subsequent Constitutional debates; thus, the Revolution itself becomes an important and ubiquitous subject area for writers attempting to situate narratives of national history. These national allegories, consciously constructed as patriotic narratives, unconsciously “bring forth” figurations that represent the official nation’s Others, people excluded …

Vitrification And Dehydration For The Preservation Of Gametes, Allison E. Moisan Jan 2006

Vitrification And Dehydration For The Preservation Of Gametes, Allison E. Moisan

LSU Doctoral Dissertations

Of the 36 species of felines in the world, all except the domestic cat are listed as endangered or threatened. To preserve the genetic diversity of felines and other species, genome resource banks have been established. Due to limited availability of germ cells for research, studies must use models to optimize the techniques before they are applied to endangered species. In this study, preservation of oocytes and spermatozoa was examined using the bovine as a model for felines. In the first series of experiments, bovine and feline oocytes were dehydrated, vitrified, warmed and cultured to assess their ability to undergo …

Population Biology And Disturbance Ecology Of A Native North American Bamboo (Arundinaria Gigantea), Paul R. Gagnon Jan 2006

Population Biology And Disturbance Ecology Of A Native North American Bamboo (Arundinaria Gigantea), Paul R. Gagnon

LSU Doctoral Dissertations

This dissertation explores effects of windstorm and fire disturbances on the clonal and reproductive biology of cane (Arundinaria gigantea Muhl., Poaceae). In this collection of studies, multiple disturbances interact in complex ways, and some interactions appear only after a substantial lag. One implication of this research is that multiple, interacting disturbances might strongly influence the boundary between monodominant and species-rich plant communities. Cane is the only bamboo native to the United States, and once covered vast areas of bottomlands in the southeastern U.S. in monodominant stands called “canebrakes.” The study took place on the Buckhorn Wildlife Management Area in Tensas …

Reading Trauma In Postmodern And Postcolonial Literature: Charlotte Delbo, Toni Morrison, And The Literary Imagination Of The Aftermath, Sylviane Finck Jan 2006

Reading Trauma In Postmodern And Postcolonial Literature: Charlotte Delbo, Toni Morrison, And The Literary Imagination Of The Aftermath, Sylviane Finck

LSU Doctoral Dissertations

Some personal or collective histories can never be completely integrated into the continuum of one's emotional life. Such stories produced in traumatic times or in disastrous events are likely to remain only partially understood or accepted. Examining the human consequence of traumatic events such as the enslavement of Africans in the United States or the attempted extermination of the Jewish people in Europe is one challenging focus of this work. It is comparatively productive, however, if these events are approached from the perspective of the trauma they have produced-an approach that suspends chronological and geographical barriers of time and space. …

Historical Fire Regimes In Southeasern Pine Savannas, Jean Marie Huffman Jan 2006

Historical Fire Regimes In Southeasern Pine Savannas, Jean Marie Huffman

LSU Doctoral Dissertations

Southeastern coastal plain pine savannas lack direct evidence of past fire regimes. As a result, uncertainty exists regarding the range of variation in frequency and seasonal timing of past fire regimes and the relative importance of anthropogenic and lightning-ignited fires. Characterization of past fire regimes is needed for effective restoration and management of these high-biodiversity ecosystems. I used dendrochronologically dated fire scars from stumps of old growth longleaf pines in a large coastal, mainland pine savanna and from dead slash pines on a small, coastal barrier island in north Florida to explore past fire regimes. In the mainland savanna, 71 …

Evaluation Of A Plasmid Delivery System For Production Of Gnrh And Ghrh In The Horse And Goat, William Andrew Storer Jan 2006

Evaluation Of A Plasmid Delivery System For Production Of Gnrh And Ghrh In The Horse And Goat, William Andrew Storer

LSU Doctoral Dissertations

The efficacy of a novel plasmid delivery system was assessed for long-term expression of gonadotropin releasing hormone (GnRH) and growth hormone releasing hormone (GHRH) in horses and goats. The efficacy of the technology was demonstrated using 3 novel plasmids: pSEAP [expressing secreted embryonic alkaline phosphatase (SEAP)], pGHRH (expressing GHRH), and pGnRH (expressing GnRH). Geldings were electroporated with a reporter plasmid expressing SEAP in 3 muscle sites. Expression of SEAP, measured from jugular plasma samples, indicated muscle specificity for uptake and expression of the plasmid. Concentrations of SEAP were greatest (P < 0.05) after pectoralis injection, which was chosen as the site for electroporation in subsequent studies. In a second experiment, stallions were electroporated with pGHRH or pSEAP to evaluate the effect of long-term GHRH treatment on the growth hormone (GH) axis and testicular function. Stallions treated with pGHRH had increased (P < 0.05) plasma concentrations of IGF-I, increased (P < 0.05) volume of accessory sex gland fluid, and increased (P < 0.05) number of normal spermatozoa in the ejaculate relative to controls. In the third experiment, stallions were electroporated with pGnRH or pSEAP to test the effects of GnRH on the reproductive axis. Treatment with pGnRH increased (P < 0.05) plasma testosterone concentrations to d 56 and increased (P < 0.01) the LH response to GnRH on d 21, but did not alter (P > 0.1) seminal characteristics evaluated after 36 d of treatment.

Two-Dimensional And High-Throughput Electrophoretic Separation Of Proteins Using Polymeric Microchips, Hamed Shadpour Jan 2006

Two-Dimensional And High-Throughput Electrophoretic Separation Of Proteins Using Polymeric Microchips, Hamed Shadpour

LSU Doctoral Dissertations

A major task in proteomics is to identify proteins from a biological sample using two-dimensional (2-D) separation prior to mass spectrometry of peptides generated via proteolytic digestion of the proteins. For 2-D separations, microfluidic devices are superior to bench top and capillary-based systems since they potentially provide higher separation efficiencies due to the minimal dead volumes produced during peak transfer between the two separation dimensions. In addition, fast separations can be envisioned because the column lengths are typically shorter in microfluidic platforms without scarifying peak capacity. High-throughput capabilities are extremely desirable for many types of bio-analytical analyses, such as understanding …

Evaluating The Spatial Ecology Of Anthrax In North America: Examining Epidemiological Components Across Multiple Geographic Scales Using A Gis-Based Approach, Jason Kenna Blackburn Jan 2006

Evaluating The Spatial Ecology Of Anthrax In North America: Examining Epidemiological Components Across Multiple Geographic Scales Using A Gis-Based Approach, Jason Kenna Blackburn

LSU Doctoral Dissertations

This dissertation explores the spatial ecology and potential pathways of infection of anthrax, Bacillus anthracis, in North America. A multi-scale approach was used to evaluate the components required for disease agent survival in the environment, interactions with wildlife, and the potential role that vectors play in anthrax transmission. First, ecological niche modeling with the Genetic Algorithm for Rule-set Production (GARP) was used to predict the geographic distribution of anthrax in the continental U.S. using case data from outbreaks between 1957 and 2005. These results were then used to produce the first quantitative, continental scale predictions of anthrax in Mexico. At …

The Epidemiology Of West Nile Virus In Louisiana, Karen Ruth Gruszynski Jan 2006

The Epidemiology Of West Nile Virus In Louisiana, Karen Ruth Gruszynski

LSU Doctoral Dissertations

West Nile virus (WNV), a member of the genus Flavivirus transmitted by mosquitoes, first appeared in the New York in 1999. Within five years WNV was detected throughout the contiguous 48 states causing disease in reservoirs and accidental hosts alike. In Louisiana, WNV was first detected in 2001 with one human case, ten equine cases, and six dead birds reported. The introduction of WNV into Louisiana presented an unique opportunity to observe an emerging disease unfold, so a study was launched to gain insight into the epidemiology of WNV in Louisiana. The first component, an environmental predictive model for West …

Studies Of Pathogenesis-Related Proteins In The Strawberry Plant: Partial Purification Of A Chitinase-Containing Protein Complex And Analysis Of An Osmotin-Like Protein Gene, Yuhua Zhang Jan 2006

Studies Of Pathogenesis-Related Proteins In The Strawberry Plant: Partial Purification Of A Chitinase-Containing Protein Complex And Analysis Of An Osmotin-Like Protein Gene, Yuhua Zhang

LSU Doctoral Dissertations

Plant chitinases and osmotin-like proteins (OLPs) are both pathogenesis-related (PR) proteins, which are implicated in plant responses to pathogen attacks and environmental stresses. In this dissertation, a chitinase-containing protein complex was purified to near homogeneity from strawberry leaf extracts. This protein complex contained at least five different chitinase molecules as revealed by activity gel assays. A previous study showed that winter rye leaves contain seven protein complexes, which consist of various combinations of a chitinase, two glucanase-like proteins (GLPs) and a thaumatin-like protein (TLP). Western blot analysis of the strawberry chitinase complex, however, did not detect the presence of any …

Heroic Individualism: The Hero As Author In Democratic Culture, Alan I. Baily Jan 2006

Heroic Individualism: The Hero As Author In Democratic Culture, Alan I. Baily

LSU Doctoral Dissertations

My study focuses on the literature of democratic morality, with specific reference to the question of "heroic individualism." I attempt to elucidate the notion of heroic individualism by examining three modern democratic moralists whose work occupies the space between politics and literature: Jean Jacques Rousseau, Thomas Carlyle and Friedrich Nietzsche. In brief, I conclude that the central aspiration of heroic individualism is to bridge the gap between writing and action, the Text and the Voice. The dialogue among Rousseau, Carlyle, and Nietzsche reveals that the problem of writing as action is central to heroic-individualist morality. Each of these authors demonstrates …

Monoclonal And Phage-Displayed Antibodies As Lipopolysaccharide Serotyping Reagents And Their Use In Typing Colony Variants Of Vibrio Vulnificus, Randall M. Schulz Jan 2006

Monoclonal And Phage-Displayed Antibodies As Lipopolysaccharide Serotyping Reagents And Their Use In Typing Colony Variants Of Vibrio Vulnificus, Randall M. Schulz

LSU Doctoral Dissertations

Vibrio vulnificus is a Gram-negative organism that is found in estuarine environments. The bacterium is capable of causing gastroenteritis, wound infections, and septicemia, often resulting in death for susceptible individuals. Monoclonal antibodies (MAbs) to five lipopolysaccharide (LPS) O-serovars have previously been used as a serotyping system in epidemiological studies. Here is the first report of two additional MAbs capable of recognizing two new LPS serovars (O6 and O7), further increasing the number of V. vulnificus that can be typed. Analysis of V. vulnificus isolates from the United States, Europe, and Asia demonstrated that the O1/O5 serovar is dominate in clinical …

Loading And Recovery Behavior Of The Human Lumbar Spine Under Static Flexion, Guntulu Selen Hatipkarasulu Jan 2006

Loading And Recovery Behavior Of The Human Lumbar Spine Under Static Flexion, Guntulu Selen Hatipkarasulu

LSU Doctoral Dissertations

Musculoskeletal disorders account for 32 percent of work related injuries and illnesses. Extensive studies have been conducted to understand and explore the factors that affect the development of musculoskeletal disorders to provide effective control strategies. One of the most important factors that allow effective control strategies is the biomechanical factors. Among the biomechanical risk factors, exposures to repetitive static and vibratory activities are known to result in musculoskeletal disorders. A ligamento–muscular reflex activity exists in humans and animals to stabilize the knee, shoulder, elbow, ankle joints, and spine. This reflex activity decreases over time when static loading is applied, which …

Once Proud Princes: Planters And Plantation Culture In Louisiana's Northeast Delta, From The First World War Through The Great Depression, James Matthew Reonas Jan 2006

Once Proud Princes: Planters And Plantation Culture In Louisiana's Northeast Delta, From The First World War Through The Great Depression, James Matthew Reonas

LSU Doctoral Dissertations

The Delta country of northeast Louisiana is a richly productive alluvial region stretching south from the Arkansas line to the confluence of the Red and Mississippi Rivers below Natchez. As the source of great cotton fortunes made during antebellum times, it reflected the Old South ideal and, for several decades after the end of the Civil War, remained firmly grounded in this old plantation culture. The economic depression of the 1890s and the coming of the boll weevil in the early 1900s, however, signaled a gradual decline that turned into full-blown dissolution in the years following the First World War. …

Evaluating Preference For Reinforcers Under Varying Schedule Requirements In Children With Developmental Disabilities, Tiffany Michelle Kodak Jan 2006

Evaluating Preference For Reinforcers Under Varying Schedule Requirements In Children With Developmental Disabilities, Tiffany Michelle Kodak

LSU Doctoral Dissertations

Previous research has shown that preference for concurrently available reinforcers can be influenced by the reinforcement schedule (DeLeon, Neidert, Anders, & Rodriguez-Catter, 2001; Tustin, 1994). However, limited research has been conducted on specific variables that may influence preference under various schedule requirements. The present study evaluated the influence of task preference, schedule, and quality of reinforcement on choice between either an arbitrary reinforcer or a functional reinforcer. Five participants diagnosed with Autism participated in the study. In the first phase, we evaluated the effects of task preference and schedule of reinforcement on choice between a 30-s break and a high …

Nutrient Constraints On Plant Community Production And Organic Matter Accumulation Of Subtropical Floating Marshes, Guerry O., Jr. Holm Jr. Jan 2006

Nutrient Constraints On Plant Community Production And Organic Matter Accumulation Of Subtropical Floating Marshes, Guerry O., Jr. Holm Jr.

LSU Doctoral Dissertations

In the cycle of delta growth and decay, peat-forming wetlands span a time and space continuum. Later in the delta cycle, freshwater floating marshes become increasingly removed from external sediment subsidy and internal nutrient cycling controls plant productivity and organic matter accumulation. An interesting question is whether increased external nutrient loading can affect the basic processes that lead to peat formation—plant production and organic matter decomposition. I conducted several field studies to understand whether belowground organic matter accumulation and decomposition were affected with increased nutrient exposure; in addition, the plant community was monitored over three years. A laboratory soil respiration …
