Brugia Phangi: Effects Of Third Stage Larvae Es Immunization On Early Migration And Parasite Establishment In Mongolian Gerbils (Meriones Unguiculatus), Ginger Ann Robertson Jan 2006

Brugia Phangi: Effects Of Third Stage Larvae Es Immunization On Early Migration And Parasite Establishment In Mongolian Gerbils (Meriones Unguiculatus), Ginger Ann Robertson

LSU Master's Theses

Brugia infections occur via the bite of an infected mosquito. Third stage infective larvae (L3) deposited on the skin during feeding migrate into the bite wound, through skin and into the lymphatic system. It is hypothesized that L3 excretory/secretory products (ES) are important in this initial phase of the infection. A model for these early migrations has been established by inoculating L3s into the dermis (ID) of the permissive gerbil host. In this model, most L3s injected ID in the louer hind limb travel to the popliteal lymph node by 3 days post infection. Adult parasites are located primarily in …

Agrobacterium Tumefaciens-Mediated Transformation Of Tobacco (Nicotiana Tabacum L.) Leaf Disks: Evaluation Of The Co-Cultivation Conditions To Increase Beta-Glucuronidase Gene Activity, Sunjung Park Jan 2006

Agrobacterium Tumefaciens-Mediated Transformation Of Tobacco (Nicotiana Tabacum L.) Leaf Disks: Evaluation Of The Co-Cultivation Conditions To Increase Beta-Glucuronidase Gene Activity, Sunjung Park

LSU Master's Theses

Agrobacterium tumefaciens-mediated transformation is generally used for genetic transformation of higher plants. Several experimental factors important for the increase of beta-glucuronidase (GUS) reporter gene activity were evaluated in this study using leaf disks of tobacco (Nicotiana tabacum L. cv. Xanthi). We found that co-cultivation temperature at 20C is the most critical factor to obtain the reproducible enhancement of GUS activity. pCAMBIA 1305.01 resulted in higher GUS activity than the other two pCAMBIA vectors 1301 and 1305.02. The highest GUS activity and transformation efficiency were achieved under the following experimental conditions: Agrobacterium tumefaciens strain LBA4404 containing pCAMBIA1305.01 was grown overnight at …

Anoxia Tolerance, Anaerobic Metabolism, And The Lack Of A Mitochondrial Permeability Transition In The Ghost Shrimp, Lepidophthalmus Louisianensis, Schmitt, 1935, Jeremy Dale Holman Jan 2006

Anoxia Tolerance, Anaerobic Metabolism, And The Lack Of A Mitochondrial Permeability Transition In The Ghost Shrimp, Lepidophthalmus Louisianensis, Schmitt, 1935, Jeremy Dale Holman

LSU Master's Theses

The ghost shrimp, Lepidophthalmus louisianensis, burrows up to meters deep in oxygen-limited marine sediments along the Gulf coast. During low tides these animals are subjected to extended periods of anoxia. The main objective of this study was to assess survival under anoxia and evaluate the physiological mechanisms that underlie the anoxia tolerance of this species. I observed large specimens of L. louisianensis (>2g) having an LT50 of 64 h under anoxia at 25º C. Smaller specimens (<1g) have a significantly higher LT50 of 113 h under identical conditions (P<0.0001). I measured whole body lactate levels in shrimp exposed to anoxia for up to 72 h, and recorded significant accumulation of this anaerobic end product (ANOVA, P<0.001). I also measured adenylates and arginine phosphate in shrimp exposed to anoxia for up to 48 h, and after a 24-h recovery period. Adenylates were not significantly altered during the anoxia regime, and reductions in arginine phosphate occurred after 12 and 24 h, but returned to normoxic values during recovery (ANOVA, P<0.001). While reserves of arginine phosphate are used to some extent to buffer losses in ATP, substantial contribution to the maintenance of energetic status comes from the high rate of anaerobic glycolysis. Energized mitochondria isolated from ghost shrimp hepatopancreas possess a pronounced ability to take up exogenous Ca2+ (compared to mitochondria-free controls) as measured by following the external free Ca …

Comparing Bermudagrass And Bahiagrass Cultivars At Different Stages Of Harvest For Dry Matter Yield And Nutrient Content, Ryan Thomas Dore'

LSU Master's Theses

Rapid growth of warm-season grasses such as bermudagrass (Cynodon dactylon) and bahiagrass (Paspalum notatum) is associated with a decline in their nutritional value. This study was initiated to provide production and composition data with different cultivars of bermudagrass (common, Russell, Jiggs) and bahiagrass (Tifton-9, Pensacola, Argentina). Dry matter (DM), ash, crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) composition and production were evaluated every two weeks for a ten-week period on six different cultivars. Also, Russell bermudagrass was evaluated in a second trial very similar to the first trial for composition and production but was started …

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 …

All The World's A Stage: Pageantry As Propaganda At The Court Of Elizabeth I, 1558-1569, Kimberly Kay Reynolds Jan 2006

All The World's A Stage: Pageantry As Propaganda At The Court Of Elizabeth I, 1558-1569, Kimberly Kay Reynolds

LSU Master's Theses

Elizabeth I of England was one of the most celebrated monarchs in history. Authors, playwrights, and artists venerated her in their art. At her accession, however, her subjects were unsure about their new queen. She was an illegitimate female ruling a religiously divided kingdom. In response to this, Elizabeth and her council initiated a propaganda campaign that created an image of Elizabeth as a wise, just, and well-beloved ruler. This thesis will examine Elizabeth’s coronation procession, the performance of plays and masques at court, and the queen’s annual progresses to show how Elizabeth and her subjects used drama, pageantry, and …

Mothers Grimm And Other House Held Tales, Holly Kay Streekstra Jan 2006

Mothers Grimm And Other House Held Tales, Holly Kay Streekstra

LSU Master's Theses

Mothers Grimm and Other House Held Tales is a body of work that uses fairy tale archetypes and narrative traditions to comment upon tensions and conflicts in sexual self-understanding. This is achieved through a reflection on attitudes that women adopt regarding their own sexuality. Such a reflection is instigated through a presentation of prominent cultural archetypes that exist, no longer as received ideas, but as a bold and entertaining expression of how sex can change our attitude towards those ideas that we often take for granted. Through an assemblage of objects and video, this body of work evokes a domestic …

Considering Blackness In George A. Romero's Night Of The Living Dead: An Historical Exploration, Jennifer Whitney Dotson Jan 2006

Considering Blackness In George A. Romero's Night Of The Living Dead: An Historical Exploration, Jennifer Whitney Dotson

LSU Master's Theses

When George A. Romero's Night of the Living Dead was released in 1968, the independent black and white zombie film stunned American moviegoers. Having assaulted the audience with a new level of violence-laden gore, Night of the Living Dead received much attention from both popular and critical audiences, with the former rushing to theaters to see the film over and over and the latter almost universally panning the film for its poor taste and gratuitous violence. Since its release, however, Night of the Living Dead has become one of the most written about horror films in American history, with critics …

Nutrient-To-Cost Comparisons Of Daily Dietary Intake, Food Security Status, And Body Mass Index In Female Food Stamp Recipients Residing In Southeast Louisiana, Shanna Lundy Jan 2006

Nutrient-To-Cost Comparisons Of Daily Dietary Intake, Food Security Status, And Body Mass Index In Female Food Stamp Recipients Residing In Southeast Louisiana, Shanna Lundy

LSU Master's Theses

Diets are typically poorer and risk of chronic disease is greatest in low-income populations. A relationship has been established in the literature between food costs and diet quality, where lower cost diets are generally those of the poorest quality. Food group intake, energy/nutrient intake, and diet cost were assessed in 64 female food stamp recipients in Southeast Louisiana. From one 24-hour dietary recall collected at the beginning of the monthly resource cycle (Day 1) and one at the end (Day 2), nutrient intakes and diet costs were able to be analyzed between different time frames. Participants were divided among food …

Performing Citizenship: Tensions In The Creation Of The Citizen Image On Stage And Screen, John William Wright Jan 2006

Performing Citizenship: Tensions In The Creation Of The Citizen Image On Stage And Screen, John William Wright

LSU Doctoral Dissertations

What does it mean to be a “citizen” of the United States? In the simplest of terms, citizenship is a limited position of identity, relegated to a narrow definition of legal and geographical position for an individual. But to be a “citizen” in America means far more than that – it becomes an accepted image of our collective identity which seeks an historical and political supremacy that allows America, and its citizens, to claim ideological status over anyone who is not a part of that nationalistic frame. The citizen has, for us, become a set of understood rights and privileges, …

"Nos Frères D'Outre-Golfe": Spiritualism, Vodou And The Mimetic Literatures Of Haiti And Louisiana, Jean-Marc Allard Duplantier Jan 2006

"Nos Frères D'Outre-Golfe": Spiritualism, Vodou And The Mimetic Literatures Of Haiti And Louisiana, Jean-Marc Allard Duplantier

LSU Doctoral Dissertations

The nineteenth-century Francophone literatures of Haiti and Louisiana are often dismissed as pale imitations of literary trends in metropolitan France. This study revisits these literatures and explores how Creole writers used borrowed ideas and imitated styles to assemble "relational" Creole identities. Two interrelated spiritual practices-the mid-century craze for "table turning" commonly known as modern Spiritualism, and the syncretistic New World religion Vodou-structured these writers' mimetic methods, enabling them to speak as, and thereby subvert the hegemony of, their cultural forebears. In France, the mid-century interest in Spiritualism provided French fantastic literature with a useful system for producing the many "revenants" …

The Business Dynamics In Telecommunication Market Consolidation, George Amstad Jan 2006

The Business Dynamics In Telecommunication Market Consolidation, George Amstad

LSU Master's Theses

The Swiss telecommunication market is quite different from the markets in surrounding European countries. The Swiss Market is characterized by a very small number of competitors and relatively high and stable prices. The model in this thesis explains shows how the limited competition enables the mobile telecommunication service providers to keep prices up. This is due to a oligopoly market situation linked to complicated laws that discourage new competitors to join the Swiss market. Later in 2006, the Swiss federal council will pass the new televisor law, which will make it significantly easier to join the Swiss market. This will …

Effects Of Smoking Cessation And Female Sex Hormones On Food Intake In Postmenopausal Women, Megan Ranae Apperson Jan 2006

Effects Of Smoking Cessation And Female Sex Hormones On Food Intake In Postmenopausal Women, Megan Ranae Apperson

LSU Master's Theses

Following smoking cessation, individuals increase their food intake. Women experience greater postcessation hyperphagia than men, and older women may increase their food intake more than younger women. Some research has suggested that postcessation increases in food intake may be macronutrient specific. However, previous investigations of macronutrient specific changes in food intake following smoking cessation have had significant methodological problems. The current study assessed changes in total food intake and macronutrient selection using the Macronutrient Self-Selection Paradigm (MSSP), a direct, laboratory based measure of food intake that is valid and reliable with respect to macronutrient intake. Fifty-five postmenopausal females completed the …

Freshwater Mussel Communities Of The Florida Parishes, Louisiana: The Importance Of Spatial Scale, Anne Raynie Bambarger Jan 2006

Freshwater Mussel Communities Of The Florida Parishes, Louisiana: The Importance Of Spatial Scale, Anne Raynie Bambarger

LSU Master's Theses

The Southeastern United States has the most diverse and imperiled freshwater mussel (Unionidae) fauna in the world. The community structure and decline of these organisms is the result of complex interactions between biotic and abiotic factors, but the limited spatial scale of most community studies has failed to elucidate the underlying mechanisms shaping community structure. Basing community assessments solely on microhabitat variables alone has lead to stark contradictions in management recommendations and opposing definitions of habitat requirements for these organisms. However, with the introduction of GIS technology into aquatic management, it is now feasible to include variables from larger spatial …

The Effects Of Micronutrients On Pullets And Broilers, Danielle Armantine Lauzon Jan 2006

The Effects Of Micronutrients On Pullets And Broilers, Danielle Armantine Lauzon

LSU Master's Theses

Two experiments were conducted to determine the availability of various vitamin E (E) sources (absorbed to verxite or adsorbed to silica) in broilers. In Experiment 1, at 100 and 300 IU supplemental E, an average of 94 and 44% of E intake from verxite and silica, respectively, was excreted in the feces, but at 30 IU E, 49 and 45% of E intake was excreted in the feces. In Experiment 2 at 30 IU, 52 and 43% of E intake from verxite and silica was excreted (source, P < 0.02). Based on these results, E adsorbed to silica is more available. Two experiments were conducted to determine the relative bioavailability of organic versus inorganic sources of either Mn or Zn. In Experiment 1, Mn as MnSO4 or a Mn amino acid complex (Availa-Mn) were compared. In Experiment 2, ZnSO4 or a Zn amino acid complex (Availa-Zn) were compared. The results indicate that Availa-Mn is a more available source of Mn than MnSO4, but Availa-Zn is not as available as a source of Zn as ZnSO4. An experiment was conducted to determine the effects of organic sources of Zn, Mn, and Cu on White Leghorn pullet performance. Treatment diets consisted of a control diet with 66 ppm Zn as ZnSO4 or a combination of ZnSO4 and Availa-Zn, 66ppm Mn as MnSO4 or a combination of MnSO4 and Availa-Mn, and 10 ppm Cu as CuSO4 or a combination of CuSO4 and a Cu amino acid complex (Availa-Cu). Diets are inorganic sources (IO), organic Zn (OZ), organic Zn and Mn (OZM), or organic Zn, Mn, and Cu (OZMC). Addition of OZM increased (P < 0.08) intestinal tensile strength and increased (P < 0.06) grams of ash per bone compared with OZMC. Pullets fed OZ had a higher (P < 0.08) bone concentration of all minerals than pullets fed OZM. Total tibia Mn was decreased (P < 0.06) by OZMC, but total tibia Cu was increased (P < 0.08) by OZ addition over IO or OZM.

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 …
