Séances, Ciénegas, And Slop: Can Collaboration Revive The Colorado Delta?, Bret C. Birdsong
Séances, Ciénegas, And Slop: Can Collaboration Revive The Colorado Delta?, Bret C. Birdsong
Scholarly Works
Issues of transboundary allocation of water resources and its environmental effects are, virtually by their very nature, ones that require collaborative solutions. In the absence of international law norms and institutions to resolve sovereign claims to the waters of international rivers, much of the decisionmaking is left to the collaborative, or negotiated, arrangements between the countries involved and their respective domestic stakeholders. This Article examines collaborative efforts to allocate waters in the Colorado River basin as they relate to the lowest reaches of that great river, the ecologically important but very fragile Colorado River Delta in Mexico. Collaboration is sometimes …
Degradation And Water Quality Dynamics Of Sugarcane Residue In South Louisiana, Jose Roberto Deras
Degradation And Water Quality Dynamics Of Sugarcane Residue In South Louisiana, Jose Roberto Deras
LSU Doctoral Dissertations
PURPOSE: This research was conducted to assess methods to manage the residue blanket to avoid open field burning in sugarcane. Experiments were conducted in the state of Louisiana to evaluate methods to asses and potentially reduce water quality issues. METHODS: Concentrations and frequencies of biological compost tea were sprayed on sugarcane combine-harvester residue blanket to increase degradation rate and reduce potential for runoff water to transport nutrients and sediments that may impair water bodies, while sustaining suitable sugarcane yield. Carbon dioxide evolution rate (mg CO2-C) and CO2 fluxes were measured in laboratory and in open field conditions; as an index …
The Case Of Human Plurality: Hannah Arendt's Critique Of Individualism In Enlightenment And Romantic Thinking, Joshua Luke Yoder
The Case Of Human Plurality: Hannah Arendt's Critique Of Individualism In Enlightenment And Romantic Thinking, Joshua Luke Yoder
LSU Master's Theses
The theme of this thesis is Hannah Arendt’s critique and ultimate rejection of the ideas of individualism developed during the Enlightenment and the Romantic periods. She rejects the Enlightenment notion of the “abstract man,” but equally rejects the notion of Romantic introspection that followed. Such a critique is important to Arendt because she makes human plurality the center for her entire system of thought. Using the French Revolution, Jewish history, and totalitarianism as her examples, Arendt explains the effects of such overtly individualistic thinking in both society and politics. The goal of this thesis is not a comprehensive look at …
Transitioning To Organic: Fertility Management In Potato Production, Lacey Theresa Dupreé
Transitioning To Organic: Fertility Management In Potato Production, Lacey Theresa Dupreé
LSU Master's Theses
An increasing demand for organic crops in the US represents a considerable opportunity for organic, as well as conventional growers interested in exploring the transition to organic production. Renewed interest in organic farming has resulted in a need for research involving organic fertilizers. Limited research has been conducted on organic vegetable production with previous research conducted primarily outside the Deep South US. Field studies were conducted at the Louisiana State University (LSU) AgCenter Burden Center to investigate the effect of three levels of pre-plant organic NPK fertilizer (8-5-5, Nature Safe) combined with a sidedress application of organic NPK fertilizer (13-0-0, …

Design, Fabrication, And Testing Of A Micro Fuel Injection Swirler For Lean Premixed Combustion In Gas Turbine Engines, Anthony Louis Giglio
Design, Fabrication, And Testing Of A Micro Fuel Injection Swirler For Lean Premixed Combustion In Gas Turbine Engines, Anthony Louis Giglio
LSU Master's Theses
Due to growing energy demands and the need for increased fuel consumption efficiency, environmental protection agencies are imposing more stringent emissions regulations on gas turbine combustion systems with emphasis on NOx emissions reduction. Emerging technological combustion schemes to reduce NOx commonly employ lean premixed combustion. Decreases in NOx are globally obtained by flame temperature decrease and locally improved by homogeneity of the reacting mixture. A new micro fuel injection swirler, capable of providing efficient and rapid mixing over a short distance, is presented in this thesis. The conception of the Micro Fuel Injection Swirler (MFIS) was motivated by the need …
Resistant Starch Is Effective In Lowering Body Fat In A Rat Model Of Human Endocrine Obesity, Julina Ann Robert
Resistant Starch Is Effective In Lowering Body Fat In A Rat Model Of Human Endocrine Obesity, Julina Ann Robert
LSU Master's Theses
Two studies were performed to determine the effects of resistant starch (RS) on body weight and fat. A 2x2 factorial design was used in both studies, and results were considered significant when p<0.05 for both studies. The first study examined the effects of RS in a high fat diet (44.8% of energy) on weight, fat, peptide-YY (PYY) levels, and cecal pH in male Sprague-Dawley rats. Rats were fed a low fat energy control diet for one week prior to diet treatment. On week two, rats were blocked by weight and fed one of the following diets for 12 weeks (n=10): low fat, energy control (LFEC); LF resistant starch (LFRS); high fat, energy control (HFEC); or high fat resistant starch (HFRS). RS did not lower weight or fat with either the HF or LF diets. RS consumption resulted in greater full and empty cecal weights, and a lower pH for the LFRS diet. This data indicate fermentation, even though weight and fat loss did not occur. This is contrary to previous reports with RS, which has been shown to decrease body fat compared to controls. The second study examined the effects of RS on the weight, fat, PYY levels, and glucagon-like peptide-1 (GLP-1) levels in female Sprague-Dawley rats. Ovariectomized (OVX) rats were used to represent rats prone to gaining weight, and sham rats represented normal rats. Rats were assigned to one of four groups (n=10): OVEC, OVRS, SHEC, or SHRS. Rats were fed the EC diet for 6 weeks prior to diet treatment to gain weight after surgery, and then blocked by weight and fat into diet treatment groups, and spent 13 weeks on treatment diets. Energy intake, total gastrointestinal weight, large intestine/cecum weight, and small intestine weight were all higher in RS fed rats relative to EC fed rats. Mesenteric, ovarian, perirenal, retroperitoneal, and total fat pads were lower in RS rats relative to EC rats. Although RS was not effective in lowering body weight or body fat in the first study, the data indicates that resistant starch may lower body weight and fat in postmenopausal women.

This study describes the antibacterial properties of synthetically-produced mixed aryl alkyl disulfide compounds as a means to control the growth of Staphylococcus aureus and Bacillus anthracis. Some of these compounds exerted strong in vitro bioactivity. Our results indicate that among the twelve different aryl substituents examined, nitrophenyl derivatives provide the strongest antibiotic activities. This may be the result of electronic activation of the arylthio moiety as a leaving group for nucleophilic attack on the disulfide bond. Small alkyl residues on the other sulfur provide the best activity as well, which for different bacteria appears to be somewhat dependent on …

The Cis-Δ2,3-Double Bond Of Phoslactomycins Is Generated By A Post-Pks Tailoring Enzyme, Nadaraj Palaniappan, Mamoun M. Alhamadsheh, Kevin A. Reynolds
Chemistry Faculty Publications and Presentations
The antifungal phoslactomycins (PLM A-F), produced by Streptomyes sp HK803, are structurally unusual in that three of their four double bonds are in the cis form (Δ12,13, Δ14,15, Δ2,3). The PLM polyketide synthase (PKS) has the predicted dehydratase catalytic domain in modules 1,2 and 5 required for establishing two of these cis double bonds (Δ12,13Δ14,15), as well as the only trans Δ6,7double bond. By contrast, the formation of the cis Δ2,3 in the unsaturated lactone moiety of PLMs has presented an enigma because the predicted dehydratase domain …

Freezing Processes In Cell Suspensions Evaluated Using Cryomicroscopy, Tathagata Acharya
LSU Master's Theses
This thesis aims at evaluating the freezing response of three different cell types, Pacific Oyster embryos, Jurkats and Helas, using the technique of cryomicroscopy. The choice of cells was primarily based on supporting ongoing research work at the Bioengineering Laboratory, Department of Mechanical Engineering at Louisiana State University in Baton Rouge. On a secondary basis, the cells were chosen based on their contrasting nature. While Pacific Oyster being a favorite food in USA calls for successful techniques of cryopreservation of their embryos in order to keep up with the growing demand, Jurkat and HeLa are undesired malignant human cells that …
Getting Warm(Er) An Investigation Into Linguistic Relativity And Its Significance In The Translation Of The English Lexical Term "Warm" Into French, Elizabeth Neuerburg Addison
Getting Warm(Er) An Investigation Into Linguistic Relativity And Its Significance In The Translation Of The English Lexical Term "Warm" Into French, Elizabeth Neuerburg Addison
LSU Master's Theses
Students of foreign languages are well aware that every language has its own vocabulary and word-for-word translations are rarely valid. It is therefore unsurprising that identifying literal translations in French for the English lexical term “warm” is problematic. This study demonstrates that not only is there a variety of French lexical terms that can be used to convey the meaning that the English lexical term “warm” conveys, but that certain French lexical terms are more likely to be used only in certain situations. Furthermore, an examination of this phenomenon through the lens of linguistic relativity has revealed differing conceptualizations of …
A Longitudinal Study Of Married Women's Probability Of Being Housewives In Reforming Urban China, Chiung-Yin Hu
A Longitudinal Study Of Married Women's Probability Of Being Housewives In Reforming Urban China, Chiung-Yin Hu
LSU Doctoral Dissertations
This study examines married women’s employment status and the factors associated with their being full-time housewives between 1989 and 2004 in urban China. I argue that the transition from a command economy to a market-oriented economy since the early 1980s has had negative impacts on married women’s labor force participation. Using six waves of the Chinese Health and Nutrition Survey (1989, 1991, 1993, 1997, 2000, and 2004), I find that the percentages of full-time housewives in urban China tripled in just 15 years, and the largest amount of growth occurred in the most recent period. Regression analyses confirm that married …
Model-Based Framework For Alloy Electrodeposition Processes, Miguel Eduardo Estrada
Model-Based Framework For Alloy Electrodeposition Processes, Miguel Eduardo Estrada
LSU Master's Theses
The electrodeposition of iron-group alloys has been widely studied due to their interest as materials used for their magnetic and thermo-physical properties. Models such as ternary NiCoFe and quaternary NiCoFeCu multilayer alloys have been previously developed to simulate mass transfer and reaction kinetics. The reactions involved in the models contain kinetic parameters such as rate constants and inverse Tafel slopes which are estimated using trial and error techniques. The previous models are limited to a set of kinetic parameters for each change in concentrations of the electrolyte. Although deposition behaviors such as anomalous codeposition are captured, functionalities to use the …
Appealing To Heaven: The Significance Of Religion In John Locke's Advocacy Of Revolution, Glenn Andrew Moots
Appealing To Heaven: The Significance Of Religion In John Locke's Advocacy Of Revolution, Glenn Andrew Moots
LSU Master's Theses
This research addresses the intersection of philosophy and theology in Locke’s philosophy, particularly his political philosophy. The justification for this inquiry is Locke’s use of the phrase “Appeal to Heaven” in the Second Treatise together with his advocacy of resistance in the Letter Concerning Toleration. The thesis begins with a brief survey of the relevant secondary literature and frames the intersection of theology and political philosophy. The thesis then seeks to justify the claim that Locke’s political ideas were motivated by religious concerns. This includes a close examination of An Essay Concerning Human Understanding, The Reasonableness of Christianity and his …
Latino Representation In U.S. Legislatures: Interests, Behavior, And Influence, Stella M. Rouse
Latino Representation In U.S. Legislatures: Interests, Behavior, And Influence, Stella M. Rouse
LSU Doctoral Dissertations
Despite the growth of Latinos in the general population and in legislatures, their impact on the political process has received little scholarly attention. In this project, I present a theoretical framework of Latino legislative behavior that draws upon two important concepts of representation- descriptive and substantive- to better understand how ethnicity influences legislative activity and whether it is dependent on such factors as institutional context, legislative composition, and constituency characteristics. The project is unique in its comprehensive analysis of the legislative process and in its mixed methodological approach which includes both quantitative and qualitative elements. The analysis involves five parts: …
An Experimental Study On The Formation Of Polycyclic Aromatic Hydrocarbons During The Pyrolysis And Oxidation Of Catechol[Ortho-Dihydroxybenzene]-A Model Compound Representative Of Structural Units In Coal, Wood, And Biomass, Shiju Thomas
LSU Doctoral Dissertations
Polycyclic aromatic hydrocarbons (PAH) formed during the pyrolysis and combustion of solid fuels like coal, wood, and biomass are widespread environmental pollutants. Since some PAH are known to exhibit carcinogenic and mutagenic activity, understanding the chemical reactions responsible for PAH formation is of utmost importance. To better understand the reactions leading to the formation of PAH from complex solid fuels, pyrolysis and oxidation experiments have been performed in an isothermal laminar-flow reactor, using the model fuel catechol (ortho-dihydroxybenzene), a phenol-type compound representative of structural entities in coal, wood, and biomass. Catechol pyrolysis experiments have also been performed in the presence …

Investigation Of Antimonide Structure Types And The Structural Studies Of Molybdates, Dixie Plaisance Gautreaux
LSU Doctoral Dissertations
This dissertation highlights the investigation of ternary lanthanide antimonide structure types and their physical properties. In particular, these ternary phases allow for the systematic investigation of the structure in an effort to correlate structure and properties. The ternary antimonides are layered structures with two-dimensional square sheets or nets, which influence the properties of these materials. In an effort to determine how structural changes influence the physical properties, various single crystals of compounds relating to the orthorhombic CeNiSb3 structure have been grown and characterized. The layered CeNiSb3 structure consists of Sb sheets, NiSb6 distorted octahedra, and CeSb9 monocapped square anti-prisms. LnNi(Sn,Sb)3 …

This piece provides a brief on those topics and their current standing Congress, and reviews one student’s experience of the annual AMA Lobby Day.
Make The Most Out Of Your Health Care Dollar: Highlights Of A Single Payer Proposal, Kristen Lee, Heidi Gollogly
Make The Most Out Of Your Health Care Dollar: Highlights Of A Single Payer Proposal, Kristen Lee, Heidi Gollogly
Quill & Scope
America's health care system is struggling on many fronts. We are paying more and getting less compared to many other industrialized countries. The staggering costs that cripple our current system can be explained by the patchwork for-profit payer system employed in this country. One solution is to introduce a single payer program funded by the taxes already paid into the system. By eliminating much of the unnecessary administrative costs, health care spending can reach those areas where it matters most--providing quality care to those who need it and access to preventative care.

What?? There’S A Genocide? Where?, Amaka Ozah, Farzana Nuruzzaman
Quill & Scope
Genocide is not a subject that people like to talk about, but the fact of the matter is that it does exist today. The genocide that is being referred to is that which is occurring in Darfur, Sudan. This genocide has claimed over 400,000 lives and displaced more than 2.5 million people since 2003. As the genocide continues, out of the sorrow arises the stories of healthcare professionals who have devoted their lives to providing medical care in the conflict-ridden countries such as Darfur. Leading the way in providing medical services in Darfur is the International Medical Corps.
Applying The Lessons Of Gps Monitoring Batterers To Sex Offenders, Pamela Foohey
Applying The Lessons Of Gps Monitoring Batterers To Sex Offenders, Pamela Foohey
Articles by Maurer Faculty
GPS monitoring of batterers appears to be an ingenious solution to one of the major flaws of the current domestic violence protective order system. What makes GPS monitoring so attractive in the case of batterers and other criminals should make it equally attractive in the case of sex offenders. Although GPS monitoring has been questioned as potentially unconstitutional as applied to sex offenders, when individually tailored, it may prove to be an effective solution to the problem of monitoring sex offenders. In the future, states and municipalities would do their citizens a service by reflecting on the lessons of GPS …

Space-Time Multiresolution Approach To Atomistic Visualization, Dipesh Bhattarai
LSU Doctoral Dissertations
Time-varying three-dimensional positional atomistic data are rich in spatial and temporal information. The problem is to understand them. This work offers multiple approaches that enable such understanding. An interactive atomistic visualization system is developed integrating complex analyses with visualization to present the data on space-time multiresolution basis facilitating the information extraction and generate understanding. This work also shows the usefulness of such an integrated approach. The information obtained from the analyses represents the system at multiple length and time scales. Radial distribution function (RDF) provides a complete average spatial map of the distribution of the atoms in the system which …

The purpose of the study was to measure the current level of communicative initiations exhibited by children enrolled in the LSU preschool program. Child communication was categorized as specific, unclear, or negative. These descriptors referred to peers ability to interpret the target child’s communication. Additionally, peer responses were recorded as either positive or negative based on their reaction to the target child’s communication. Children identified with either low levels of communicative initiation or unclear/negative communications were targeted for the intervention. Single-subject research methods were used to record each child’s communicative behaviors. A least-to-most assistive prompting (Horner & Keilitz, 1975) intervention …
Impact Damage Between The Collision Of A Vessel And Protective Fender Systems, Paul Joseph Kocke
Impact Damage Between The Collision Of A Vessel And Protective Fender Systems, Paul Joseph Kocke
LSU Master's Theses
Vessel collision with bridge pilings can cause a catastrophic event and are occurring at an alarming rate. Such events can lead to the collapse of a bridge, causing deaths, shutting down a primary route of transportation and costing millions of dollars in repairs. Today, the AASHTO Bridge Code gives designers a methodology toward designing bridge pilings to withstand the impact of an errant vessel. However, bridges designed before this code was written require a protective system that is capable of redirecting a colliding vessel without causing severe damage to the pilings or the vessel. This research will look into three …

Legislative Participation In The American States: Determinants And Consequences, Mileah Kay Kromer
LSU Doctoral Dissertations
This research seeks to analyze the variability in participation across legislators at the state level and to consider the potential consequences of participatory behavior. In this dissertation, I draw on theories of political participation, legislative goals, and state political institutions to explain participation in state legislative activities. To begin with, I examine legislative participation across the legislative process, considering the determinants of sponsorship and roll-call participation. Next, I examine the consequences that participation has for legislators focusing on challenger emergence in the general election. My research demonstrates that legislative participation varies systematically across individual, institutional, and state level variables. However, …
