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 …

Spectral Analysis Of Total Suspended Solids Mixtures For Solids Composition Determination, Curtis W. Sutherland Jan 2006

Spectral Analysis Of Total Suspended Solids Mixtures For Solids Composition Determination, Curtis W. Sutherland

LSU Doctoral Dissertations

Total Suspended Solids (TSS) analysis provides an initial and very basic measure for study and characterization of water quality. The present tedious procedures used for the identification of different solids constituents present in TSS and for the classification or insight into the origins of those solids are time-consuming and expensive. The research reported herein investigates the use of instrumental analysis using reflectance spectra of TSS as an attractive alternative to sufficiently characterize and identify TSS in a more rapid and economical method that could be used to study TSS transport and to identity TSS points of origin.

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 …

The Effectiveness Of Virtual Facilitation In Supporting Gdss Appropriation And Structured Group Decision Making, Harold Joseph Lagroue Jan 2006

The Effectiveness Of Virtual Facilitation In Supporting Gdss Appropriation And Structured Group Decision Making, Harold Joseph Lagroue

LSU Doctoral Dissertations

Since their introduction a quarter of a century ago, group decision support systems (GDSS) have evolved from applications designed primarily to support decision making for groups in face-to-face settings, to their growing use for “web conferencing,” online collaboration, and distributed group decision-making. Indeed, it is only recently that such groupware applications for conducting face-to-face, as well as “virtual meetings” among dispersed workgroups have achieved mainstream status, as evidenced by Microsoft’s ubiquitous advertising campaign promoting its “Live Meeting” electronic meeting systems (EMS) software. As these applications become more widely adopted, issues relating to their effective utilization are becoming increasingly relevant. This …

Validity Of The Reflux Symptoms Index For Post-Pubescent Female Vocalists, Natalie Herpin Overall Jan 2006

Validity Of The Reflux Symptoms Index For Post-Pubescent Female Vocalists, Natalie Herpin Overall

LSU Master's Theses

The Reflux Symptoms Index (RSI), a nine-item self-rated questionnaire, has been suggested as a way of monitoring severity of laryngopharyngeal reflux (LPR) symptoms during treatment. However, limited research has been conducted to assess the validity of the RSI as a way of identifying severity of laryngopharyngeal reflux (LPR) symptoms as differentiated from gastroesophageal reflux (GER) symptoms. Twenty-five post-pubescent female vocalists participated by completing a one-hour voice evaluation, including a Voice Handicap Index (VHI), an RSI, a Reflux Finding Score (RFS) completed with videostroboscopy for visualization of the laryngeal cavity, and analysis of an acoustic sample with the Multi-Dimensional Voice Profile …

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 …

Swamp Tours In Louisiana Post Hurricane Katrina And Hurricane Rita, Dawn Schaffer Jan 2006

Swamp Tours In Louisiana Post Hurricane Katrina And Hurricane Rita, Dawn Schaffer

LSU Master's Theses

Hurricanes Katrina and Rita made landfall in southern Louisiana during August and September 2005, respectively. Prior to these storms swamp tours were a popular nature-based tourism experience that entertained visitors while teaching them about local flora, fauna, and culture. The number of swamp tour businesses in the state was slowly increasing. The purpose of this study was to determine how many swamp tours were operating after the hurricanes, what type of damage they sustained, and how they repaired their businesses. Differences between those tours that remained open after the hurricanes and those that closed were also examined. A 3-phase mail …

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 …

Detection And Survival Of Escherichia Coli O157:H7 In Cattle Water Troughs And The Effects Of Cetylpyridinium Chloride Against Escherichia Coli O157:H7 Biofilms On The Surface Of Stainless Steel, Sajida Begum Plauche Jan 2006

Detection And Survival Of Escherichia Coli O157:H7 In Cattle Water Troughs And The Effects Of Cetylpyridinium Chloride Against Escherichia Coli O157:H7 Biofilms On The Surface Of Stainless Steel, Sajida Begum Plauche

LSU Doctoral Dissertations

Escherichia coli O157:H7 is an emerging food pathogen that was first identified as a cause of illness in 1982. According to CDC (The Center for Disease Control and Prevention) estimates, E. coli O157:H7 is responsible for about 73,000 illnesses, 2,000 hospitalizations and 60 deaths in the United States each year. Cattle are the principal reservoir of E. coli O157:H7. Contamination of feed and drinking water with cattle feces is an importance factor in the prevalence of infection in cattle which, in turn, results in contamination of food and the environment. Escherichia coli O157:H7 is a very persistent pathogen and has …

Voluntary Childlessness In The United States: Recent Trends By Cohort And Period, Laurie Chancey Jan 2006

Voluntary Childlessness In The United States: Recent Trends By Cohort And Period, Laurie Chancey

LSU Master's Theses

Most large-scale studies on voluntary childlessness since the waning of the baby boom provide cross-sectional estimates for a single time period. They cannot be synthesized to estimate change because of the varied definitions used to operationalize voluntary childlessness. In this study, I use data from the 1973-2002 cycles of the National Survey of Family Growth (NSFG) to estimate change in voluntary childlessness using a consistent definition by period and birth cohort. I find that voluntary childlessness stayed relatively constant through the seventies and eighties, but showed a large increase from the mid-nineties to 2002. I show that voluntary childlessness increased …

2,6-Hexadecadiynoic Acid And 2,6-Nonadecadiynoic Acid - Novel Synthesized Acetylenic Fatty Acids As Potent Antifungal Agents, Nestor Carballeira, David Sanabria, Clarisa Cruz, Keykavous Parang, Baojie Wan, Scott Franzblau Jan 2006

2,6-Hexadecadiynoic Acid And 2,6-Nonadecadiynoic Acid - Novel Synthesized Acetylenic Fatty Acids As Potent Antifungal Agents, Nestor Carballeira, David Sanabria, Clarisa Cruz, Keykavous Parang, Baojie Wan, Scott Franzblau

Pharmacy Faculty Articles and Research

The hitherto unknown 2,6-hexadecadiynoic acid, 2,6-nonadecadiynoic acid, and 2,9-hexadecadiynoic acid were synthesized in two steps and in 11–18% overall yields starting from either 1,5-hexadiyne or 1,8-nonadiyne. Among all the compounds 2,6-hexadecadiynoic acid displayed the best overall antifungal activity against both the fluconazole resistant Candida albicans strains ATCC 14053 and ATCC 60193 (MIC = 11 μM) and against Cryptococcus neoformans ATCC 66031 (MIC < 5.7 μM). The 2,9-hexadecadiynoic acid did not display any significant cytotoxicity against the fluconazole resistant C. albicans strains, but it showed fungitoxicity against C. neoformans ATCC 66031 with a MIC value of <5.8 μM. Other fatty acids, such as 2-hexadecynoic acid, 5-hexadecynoic acid, 9-hexadecynoic acid, and 6-nonadecynoic acid were also synthesized and their antifungal activities compared. The 2-hexadecynoic acid, a known antifungal fatty acid, exhibited the best antifungal activity (MIC = 9.4 μM) against the fluconazole resistant C. albicans ATCC 14053 strain, but it showed a MIC value of only 100 μM against C. albicans ATCC 60193. The fatty acids 2,6-hexadecadiynoic acid and 2-hexadecynoic acid also displayed a MIC of 140–145 μM towards Mycobacterium tuberculosis H37Rv in Middlebrook 7H12 medium. In conclusion, 2,6-hexadecadiynoic acid exhibited the best fungitoxicity profile compared to other analogues. This diynoic fatty acid has the potential to be further evaluated for use in topical antifungal formulations.

High Harmonic Generation By Short Laser Pulses: Time-Frequency Behavior And Applications To Attophysics, Mitsuko Murakami Jan 2006

High Harmonic Generation By Short Laser Pulses: Time-Frequency Behavior And Applications To Attophysics, Mitsuko Murakami

LSU Doctoral Dissertations

High harmonic generation (HHG) is a process in which noble gas atoms excited by an intense laser field at frequency ω1 emit radiation of higher frequencies that are odd integer multiples of ω1. Driven by an infrared laser, high harmonic radiation can span from the optical into the extreme ultraviolet (XUV) frequency range. In this thesis, I study HHG using short laser pulses by solving the time-dependent Schrödinger equation (TDSE). In particular, I will focus on calculating and controlling the time-dependent instantaneous frequency (chirp) of high harmonics. The harmonic chirp is a direct consequence of the atom-field …

Integrating Micro-Scale Separations To Matrix Assisted Laser Desorption And Ioniation Time Of Flight Mass Spectrometry (Maldi-Tof-Ms) For Protein Analysis, Harrison K. Musyimi

LSU Doctoral Dissertations

This dissertation describes the integration of micro-scale separations to matrix assisted laser desorption and ionization time-of-flight mass spectrometry (MALDI TOF MS) for protein analysis. MALDI MS provides unsurpassed accurate mass measurements of intact bio-molecules, for example peptides and proteins, which in turn generate high molecular specificity enabling the identity, function and structure of these molecules to be characterized. However, in order to realize the full potential of MS in proteomic studies, integrated sample processing on automated and high throughput platforms is required to address the complexity, diversity and the dynamic range of proteomic analysis. The work described here contributes towards …

Direct Detection Of Homocysteine And Syntheses Of Lanthanide Complexes As Biosensors, Weihua Wang Jan 2006

Direct Detection Of Homocysteine And Syntheses Of Lanthanide Complexes As Biosensors, Weihua Wang

LSU Doctoral Dissertations

At elevated levels, homocysteine (Hcy) is a risk factor for cardiovascular diseases and Alzheimer’s disease. It’s also implicated in a number of other diseases such as neural tube defects, pregnancy complications, and renal failures. The monitoring of Hcy levels in plasma is of current concern. To date, the biochemical mechanism by which Hcy is involved in disease states is unclear. Herein, we describe highly selective colorimetric methods for the direct determination of Hcy. Inexpensive, commercially available materials are reported. The results show potential application for the detection of Hcy in human blood plasma. Additionally, new HPLC postcolumn detection methods for …

Between Representation And Practice: Contesting Public Space In New Orleans' Jackson Square, Rebecca A. Sheehan Jan 2006

Between Representation And Practice: Contesting Public Space In New Orleans' Jackson Square, Rebecca A. Sheehan

LSU Doctoral Dissertations

Recent geographic research on public space focuses largely on either the past or present. Using historical and ethnographic methods, I contribute to understanding public space over time from an everyday point of view, a variety of social scales. Further, departing from a generally political-protest focus that much geographic literature centers on, my study explores the multifaceted areas of the political, cultural, and economic in public space. Thus, I show that the need for public space expands beyond protest voices into other realms that form and inform identity. Through New Orleans’ Jackson Square, these prospects of public space demonstrate “a world …

Communicating The Modern Entrepreneurial University In The 21st Century: A Case Study Of Academic Capitalism And Media Messaging In The Pursuit Of Revenues And National Prominence At Louisiana State University, Charles F. Zewe

LSU Doctoral Dissertations

American public universities have passed through three stages of development: the religious, the philanthropic/land-grant, and the federal research university. Squeezed by government budget cuts and demands for more money to pay for research and faculty raises, U.S. higher education has entered a fourth phase, the entrepreneurial university. Public universities are increasingly capitalizing on the intellectual property of their faculty and students to sustain themselves and expand. Administrators spout free-market rhetoric as faculty attempt to commercialize research by creating spin-off companies. Using Louisiana State University as a case study, this dissertation, applies a combination of organizational knowledge creation and resource dependence …

Domesticating The Exotic Species: International Biodiversity Law In Canada, Natasha Affolder Jan 2006

Domesticating The Exotic Species: International Biodiversity Law In Canada, Natasha Affolder

All Faculty Publications

While a significant body of international and regional agreements now addresses habitat preservation, wildlife protection, and biological diversity, these advances on the international level often fail to be effectively translated into domestic law. In this article, the author argues that international biodiversity law is being treated in Canada as "exotic". It is peppered into parties' submissions without a principled explanation of its role in Canadian law, receives little consideration from the courts, and must ultimately rely on non-legal means of enforcement. The author examines the jurisprudence dealing with four major biodiversity treaties. She notes that the judicial treatment of these …

Schottky Field Effect Transistors And Schottky Cmos Circuitry, Reinaldo Vega Jan 2006

Schottky Field Effect Transistors And Schottky Cmos Circuitry, Reinaldo Vega

Theses

It was the primary goal (and result) of the presented work to empirically demonstrate CMOS operation (i.e., inverter transfer characteristics) using metallic/Schottky source/drain MOSFETs (SFETs - Schottky Field Effect Transistors) fabricated on silicon-on-insulator (SOI) substrates - a first-ever in the history of SFET research. Due to its candidacy for present and future CMOS technology, many different research groups have explored different SFET architectures in an effort to maximize performance. In the presented work, an architecture known as a "bulk switching" SFET was fabricated using an implant-to-silicide (ITS) technique, which facilitates a high degree of Schottky barrier lowering and therefore an …

Red And Black Tides: Quantitative Analysis Of Water-Leaving Radiance And Perceived Color For Phytoplankton, Colored Dissolved Organic Matter, And Suspended Sediments, Heidi M. Dierssen, Raphael M. Kudela, John P. Ryan, Richard C. Zimmerman Jan 2006

Red And Black Tides: Quantitative Analysis Of Water-Leaving Radiance And Perceived Color For Phytoplankton, Colored Dissolved Organic Matter, And Suspended Sediments, Heidi M. Dierssen, Raphael M. Kudela, John P. Ryan, Richard C. Zimmerman

OES Faculty Publications

Using field measurements and quantitative modeling, we demonstrate that red coloration of the sea surface is not associated with any particular group of phytoplankton and is strongly dependent on the physiology of the human visual system. Red or brown surface waters can be produced by high concentrations of most types of algae, colored dissolved organic matter, or suspended sediment. Even though light reflected by red tides commonly peaks in the yellow spectral region (570–580 nm), human color perception requires consideration of the entire spectrum of light relative to receptors within the human eye. The color shift from green to red …
