A Study Of The Interactions Of Lipid Bilayers And Dendrimers Using Small Angle X-Ray Scattering And Freeze Fracture Transmission Electron Microscopy, Derek R. Dorman Jan 2010

A Study Of The Interactions Of Lipid Bilayers And Dendrimers Using Small Angle X-Ray Scattering And Freeze Fracture Transmission Electron Microscopy, Derek R. Dorman

LSU Doctoral Dissertations

Lipids are fundamental to all life forms, a key component of cell walls, and essential to proper respiratory function. They are amphiphilic molecules and readily form bilayers. Dendrimers are designer molecules that can be tailored to provide a variety of endgroup moieties, sizes, and charges. The interaction of liposomes and dendrimers can provide information on how medicine interacts with cells and an array of unique structures can be imagined from their assembly into superstructures. Polypropylenimine tetraamine (DAB-Am) and 1-directional arborol dendrimers have been studied in different molar concentrations with 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) bilayers. One-directional arborols are amphiphilic dendrimers with a hydrophilic …

Upland Nesting Waterfowl Population Responses To Predator Reduction In North Dakota, Matthew R. Pieron Jan 2010

Upland Nesting Waterfowl Population Responses To Predator Reduction In North Dakota, Matthew R. Pieron

LSU Doctoral Dissertations

Population growth for mallards (Anas platyrhynchos), and presumably other upland nesting ducks, in the Prairie Pothole Region is most sensitive to nest success, and nest success is most strongly influenced by predation. I evaluated the efficacy of reducing predator populations to improve nest success and increase local breeding populations of upland nesting ducks on township-sized (93.2 km2) management units in eastern North Dakota, USA, during 2005−2008. I also examined potential territorial limitations on local population growth for mallards. Trappers annually removed an average of 245 predators per trapped site. I monitored 7,489 nests on 7 trapped and 5 nontrapped sites, …

In Vitro And In Vivo Evaluation Of A Brucella Putative Hemagglutinin, Lauren E. Duhon Jan 2010

In Vitro And In Vivo Evaluation Of A Brucella Putative Hemagglutinin, Lauren E. Duhon

LSU Doctoral Dissertations

Brucellosis, a zoonotic disease caused by Brucella spp., presents both health and economic difficulties for livestock, wildlife, and humans. While brucellosis is nearly eradicated in the United States, the disease remains detrimental in many countries worldwide. Attempts to produce a safe and effective small ruminant vaccine have been met with limited success. The current vaccine for bovine brucellosis in the United States is B. abortus RB51. This strain transiently colonizes the host and induces a cell-mediated immune response. Levels of protection have not been demonstrated in goats and thus it is considered a relatively poor caprine vaccine that probably does …

Dissolution Of Chitosan In Ionic Liquids For Acylation Chemistry And Formation Of Cellulose-Chitosan Blends, Cristina Stefanescu Jan 2010

Dissolution Of Chitosan In Ionic Liquids For Acylation Chemistry And Formation Of Cellulose-Chitosan Blends, Cristina Stefanescu

LSU Doctoral Dissertations

Dissolution of chitosan in ionic liquids was accomplished. It has been shown that 1-butyl-3-methylimidazolium acetate (BMIMAc) is a better solvent than 1-butyl-3-methylimidazolium chloride (BMIMCl). Dissolution of chitosan in BMIMCl required a prior regeneration of chitosan from 1% acetic acid solution. In the case of BMIMAc, both dried chitosan and regenerated chitosan from acetic acid solution have been dissolved in a relatively short amount of time. While concentrations up to 2 wt% of chitosan in BMIMCl could be obtained, concentrations of 10 wt % of chitosan in BMIMAc were realized. Homogeneous phthalation and benzoylation of chitosan were achieved in these ionic …

Effect Of Resistant Starch On Microbial Content Of The Intestinal Tract, Reshani Nisansala Senevirathne Jan 2010

Effect Of Resistant Starch On Microbial Content Of The Intestinal Tract, Reshani Nisansala Senevirathne

LSU Doctoral Dissertations

Resistant starch (RS) increases beneficial gastro-intestinal bacterial populations simultaneously increasing short-chain fatty acids (SCFA) such as butyrate. Butyrate acts as energy source for epithelial cells of colonic mucosa which stimulates intestinal cell proliferation and has been implicated as important in reducing obesity, diabetes and cancer. The Lactobacillus spp, Bifidobacterium spp, Bacteroides thetaiotaomicron, Clostridium cluster IV and Clostridium cluster XIV are mainly involved in the production of butyrate by fermenting RS in the large intestine. With age there is a decline in these gut bacteria, but in the present study RS and diet restriction both enhanced the bacteria involved in butyrate …

Retrotransposon-Mediated Genomic Dynamism, Thomas Joshua Meyer Jan 2010

Retrotransposon-Mediated Genomic Dynamism, Thomas Joshua Meyer

LSU Doctoral Dissertations

Retrotransposons, a class of mobile elements, generate new copies in host genomes using RNA intermediates and reverse transcribing new copies into new loci. As such, the copy numbers of many active retrotransposon families increase dramatically over time. For example, ~42% of the human genome is comprised of retrotransposon sequences. The insertion activity of these elements, and the high degree of identity existing between the copies, have been shown to significantly impact the structure and stability of genomes, contributing in various ways from exon shuffling to inversions and from non-allelic homologous recombination to altering gene regulation. The two most successful mobile …

The Role Of Bone Marrow In Siv Pathogenesis Using The Rhesus Macaque Model, Amy F. Gill Jan 2010

The Role Of Bone Marrow In Siv Pathogenesis Using The Rhesus Macaque Model, Amy F. Gill

LSU Doctoral Dissertations

CD4+ memory T cells are depleted in mucosal tissues post human immunodeficiency virus (HIV) and simian immunodeficiency virus (SIV) infection without restoration to pre-infection levels during progressive course of disease. Bone marrow (BM) as a hematopoietic organ has been investigated for hematologic and morphologic changes during HIV infection. However, BM as a primary lymphoid tissue during HIV infection has been poorly characterized. We proposed BM was also a site of CD4+ T cell depletion driven by increased apoptosis during progressive HIV disease. We chose to investigate bone marrow changes using the premier non-human primate Rhesus macaque SIV model for the …

Temporal Reframing Of Prices: A Conceptual Framework, Mazen Jaber Jan 2010

Temporal Reframing Of Prices: A Conceptual Framework, Mazen Jaber

LSU Doctoral Dissertations

Research on consumer’s response to pricing tactics has been plentiful and is still ongoing. One strategy that research has sought to explain and endorse is pennies-a-day (Gourville, 1998), where the cost of a product is expressed as a small ongoing expense. This dissertation tests two competing theories that may explain the effect of PAD on consumer participation intentions. The first theory, marketing exchange (Bagozzi, 1975) predicts different effects across exchange type; in particular, generalized exchange (charity) and restricted exchange (consumer products and services). The second theory, mental budgeting (Heath and Soll, 1996) predicts different effects across expense type; this study …

Transactional Distance Theory: The Effect Of Disseminating Educational Messages To Frontline Nurses In An Acute Care Hospital Setting, Wanda G. Hughes Jan 2010

Transactional Distance Theory: The Effect Of Disseminating Educational Messages To Frontline Nurses In An Acute Care Hospital Setting, Wanda G. Hughes

LSU Doctoral Dissertations

Registered nurses (RNs)working in acute care hospitals that provide services 24 hours a day 7 days a week with a variety of schedules are a challenge for Nurse Managers to communicate rapidly changing, important educational messages in a timely and efficient manner. These RNs can be considered dispersed, or distanced, employees from their Nurse Managers. Moore’s (1972) Theory of Transactional Distance was the theoretical framework to explore the effects of disseminating educational messages via email from Nurse Managers to frontline RNs working in an acute care hospital that provides services 24 hours a day 7 days a week. A researcher-developed …

The Development Of Primary And Secondary Memory And Their Relationship To Fluid Intelligence, Sharon Diane Eaves Jan 2010

The Development Of Primary And Secondary Memory And Their Relationship To Fluid Intelligence, Sharon Diane Eaves

LSU Doctoral Dissertations

Researchers have been able to link working memory to many important cognitive abilities throughout the life span. Two of the unanswered questions about working memory are what cognitive processes function during working memory task performance and how do these processes directly relate to intelligence? A recent model (Unsworth & Engle, 2006) suggested that performance on working memory tasks was determined by two abilities: the capacity of primary memory and the ability to efficiently retrieve information from secondary memory. In the current study, we extended Unsworth and Engle’s (2006) methodology to include two groups of children (ages 8-9 and 10-11). Our …

In Vivo And In Vitro Pathogenesis Of Francisella Asiatica In Tilapia Nilotica (Oreochromis Niloticus), Esteban Soto Jan 2010

In Vivo And In Vitro Pathogenesis Of Francisella Asiatica In Tilapia Nilotica (Oreochromis Niloticus), Esteban Soto

LSU Doctoral Dissertations

Francisella asiatica is a Gram negative, facultative intracellular pathogen that causes fish francisellosis. In this project, homologues to the F. tularensis iglABCD genes were found present in F. asiatica. As few as 23 F. asiatica bacteria injected in the peritoneum were found capable of causing mortalities in tilapia nilotica (Oreochromis niloticus), and even fewer were enough to cause pathological changes. We examined the in vivo and in vitro interaction of F. asiatica wild type (WT) and a ÄiglC strain with tilapia and tilapia head kidney derived macrophages (HKDM). The ÄiglC was found to be attenuated following intraperitoneal and immersion challenges …

Writing About The South "In Her Own Way": Gender And Region In The Work Of Southern Women Playwrights, Casey Kayser Jan 2010

Writing About The South "In Her Own Way": Gender And Region In The Work Of Southern Women Playwrights, Casey Kayser

LSU Doctoral Dissertations

This dissertation examines how identity—gender, race, sexuality, regional affiliation—intersects with considerations of the dramatic genre, commercial and critical factors in the American theatre, and understandings about the American South to complicate how contemporary southern women playwrights represent region. In light of the always-already "performative" nature of the South, and geographical, commercial, and ideological factors that set the South in opposition to the North, southern women playwrights face additional difficulties in navigating issues of authenticity and simulacra, the universal versus the specific, ideas about southern "backwardness" versus northern sophistication, and audience participation in fetishizing or distancing the South. Using drama as …

Dietary Resistant Starch Improved Maternal Glycemic Control In Goto-Kakizaki Rat, Li Shen Jan 2010

Dietary Resistant Starch Improved Maternal Glycemic Control In Goto-Kakizaki Rat, Li Shen

LSU Doctoral Dissertations

Treatment for maternal hyperglycemia is limited on account of safety concerns for fetus. Our previous work has shown that inclusion of resistant starch in the diet decreases body fat accumulation in rodents, increases GLP-1 at both the gene expression level and plasma levels, and improves glucose tolerance in STZ-induced diabetic mice. However, studies concerning dietary resistant starch and maternal hyperglycemia are scarce. In this project, we examined the effects of dietary resistant starch in pregnant Goto-Kakizaki (GK) rats to improve glycemic control. Animal experiments were conducted to test the hypotheses. In study 1, the female GK rats were randomly grouped …

Fabrication Of Receptor-Modified Microfluidic Surfaces For Applications In Glycoprotein Screening, Jennifer Macalindong De Guzman Jan 2010

Fabrication Of Receptor-Modified Microfluidic Surfaces For Applications In Glycoprotein Screening, Jennifer Macalindong De Guzman

LSU Doctoral Dissertations

Glycoproteins have long been identified to have a profound association with human pathological processes, and they are much sought after as potential biomarkers to aid in the early diagnosis and clinical prognosis of cancers and diseases. There is currently high demand for high-throughput and low–limit–of–detection techniques that can afford profiling of the glycoproteome. Micro-total analysis systems (µTAS) based on microfluidics have the potential to fulfill these requirements, but in order to reduce the complexity of the protein pool, the µTAS devices must contain a pre-isolation and enrichment component. The research project undertaken here involved derivatization of microfluidic …

"Blessed Be The Critics Of Newspapers": Journalistic Criticism Of Journalism 1865-1930, Yasmine Tarek Dabbous Jan 2010

"Blessed Be The Critics Of Newspapers": Journalistic Criticism Of Journalism 1865-1930, Yasmine Tarek Dabbous

LSU Doctoral Dissertations

This study examined journalistic press criticism between 1865 and 1930. It sought to understand how the first modern journalists conceived of their profession in a period of great transitions. As the study revealed, journalists writing about journalism between 1865 and 1930 discussed recurring themes such as commercialization, sensationalism, advertising, and ethics. They expressed ambivalence toward the rise of big business in their field and the consequences it could have on the quality of the work. In the process, journalists also defined journalism as a profession providing a public service or as a business aiming solely for circulation and profit. Definitions …

Improving Software Quality Using An Ontology-Based Approach, Yixin Luo Jan 2010

Improving Software Quality Using An Ontology-Based Approach, Yixin Luo

LSU Doctoral Dissertations

Ensuring quality in software development is a challenging process. The concepts of anti-pattern and bad code smells utilize the knowledge of reoccurring problems to improve the quality of current and future software development. Anti-patterns describe recurring bad design solutions while bad code smells describe source code that is error-free but difficult to understand and maintain. Code refactoring aims to remove bad code smells without changing a program’s functionality while improving program quality. There are metrics-based tools to detect a few bad code smells from source code; however, the knowledge and understanding of these indicators of low quality software are still …

The Achievement Of Business Education Students On High School Core Subjects, Mohd Khata Bin Jabor Jan 2010

The Achievement Of Business Education Students On High School Core Subjects, Mohd Khata Bin Jabor

LSU Doctoral Dissertations

The importance of academic courses taken during high school has been well documented. It could determine the students’ achievement in high school, affect the students’ ability to transition to postsecondary education and expand the students’ choice of postsecondary majors and degree options (Laird, Chen, & Levesque, 2006). This study examined whether enrollment in business education is related to achievements in high school core subjects. The rationale for the study is to determine if business education contributes to the academic achievement of high school students. This study used the data from the National Assessment of Educational Progress (NAEP) High School Transcript …

Monstrous Bodies: Femininity And Agency In Young Adult Horror Fiction, June Pulliam Jan 2010

Monstrous Bodies: Femininity And Agency In Young Adult Horror Fiction, June Pulliam

LSU Doctoral Dissertations

Young Adult horror fiction with female protagonists presents sympathetically the untenable situation of adolescent girls within society whereby they are increasingly pressured to embody a doll-like feminine ideal that deprives them of voice and agency. In Young Adult horror fiction, the monstrous Other problematizes what is presented to girls as “normal” and “natural” feminine behavior. As a double with a difference, the monstrous Other is an iteration of femininity whose similarity to the original implies the possibility of resisting restrictive gender roles. Because in Young Adult horror fiction the monstrous Other is nearly always a sympathetic character, it is fairly …

The State Of Education In Louisiana: Trend Analyses Of Student Achievement, Student Matriculation, And Student Behavior In The Accountability Era, Jonathon Anthony Szymanski

LSU Doctoral Dissertations

Public education has long been the subject of public discontent. Historical events such as the Soviet launch of Sputnik in 1957, the Civil Rights Movement of the 1950s and 1960s, and repeated media reports that U.S. students were outscored by students in many other countries on international tests each prompted federal and state legislation aimed to reform public education. Following a presentation of the relative standing of the United States on three international tests, the history of public schooling in six states, Texas, North Carolina, Kentucky, Maryland, Florida, and Louisiana, is discussed. The central focus of the study is student …

Artisanal Whaling In The Atlantic: A Comparative Study Of Culture, Conflict, And Conservation In St. Vincent And The Faroe Islands, Russell Fielding Jan 2010

Artisanal Whaling In The Atlantic: A Comparative Study Of Culture, Conflict, And Conservation In St. Vincent And The Faroe Islands, Russell Fielding

LSU Doctoral Dissertations

Whalers from the Caribbean island of St. Vincent and the North Atlantic archipelago of the Faroe Islands hunt pilot whales and a variety of other small cetaceans for food. Vincentian whalers use harpoons, thrown by hand or fired from a modified shotgun mounted on the boat. Faroese whalers, using several dozen boats, work cooperatively to drive an entire pod of whales ashore, where shore-based whalers are waiting to complete the kill with traditional whaling knives. Vincentian whaling traces its origins to the late nineteenth century. Records of Faroese whaling date to the late sixteenth century but the practice is thought …

Iron (Iii) Oxide And Copper (Ii) Oxide Mediated Formation Of Pcdd/Fs From Thermal Degradation Of 2-Mcp And 1,2-Dcbz, Shadrack Kirwa Nganai Jan 2010

Iron (Iii) Oxide And Copper (Ii) Oxide Mediated Formation Of Pcdd/Fs From Thermal Degradation Of 2-Mcp And 1,2-Dcbz, Shadrack Kirwa Nganai

LSU Doctoral Dissertations

Formation of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) which occurs inexorably from most thermal and combustion processes constitutes a major toxic component of environmental pollutants. Generally, it is well established that transition metal-mediated reactions account for the majority of PCDD/F emissions from combustion sources. Specifically, both copper and iron ions, which occur abundantly in combustion generated particulate matter, are considered probably the most active in promoting PCDD/F formation typically in the low temperature post-combustion zone and flue gas pollution control devices. It has also been demonstrated that chlorinated phenols are key intermediates in essentially all pathways of PCDD/F formation. Chlorinated benzenes …

Population Genetics And Systematics Of A Species-Rich Clade Of Neotropical Reef Fishes, The Tubeblenny Genus Acanthemblemaria, Ron Israel Eytan

LSU Doctoral Dissertations

Neotropical coral reef fish communities are species-poor compared to those of the Indo-West Pacific. An exception to that pattern is the blenny clade Chaenopsidae, one of only three coral reef fish families endemic to the Neotropics. Within the chaenopsids, the genus Acanthemblemaria is the most species-rich. To understand the origin and maintenance of genetic and species diversity in these fishes, I characterized the population genetics for two Acanthemblemaria species, reconstructed the phylogeny of the group, and identified suites of correlated morphological characters responsible for the distinctive skull morphology of these fishes. By combining nuclear and mitochondrial sequence data I was …
