Evaluation Of Interwell Connectivity Of Little Creek Field, Mississipii [Sic] From Production Data, Gbemisola Yewande Ogunyomi Jan 2009

Evaluation Of Interwell Connectivity Of Little Creek Field, Mississipii [Sic] From Production Data, Gbemisola Yewande Ogunyomi

LSU Master's Theses

The understanding of geological characteristics and heterogeneity of a reservoir enables better decisions for reservoir development. Statistical methods use universally available injection and production rate data to help evaluate reservoir characteristics and behavior.In this research project, statistical methods typically used to infer communication between injector-producer well pairs in a waterflood reservoir using only production and injection rate data are applied to a CO2 flood. The multivariate linear regression (MLR) technique computes weighting coefficients possibly related to the fraction of the flow in a producer that comes from each of the injectors (Albertoni and Lake, 2002). MLR was applied to the …

Dispute Resolution And The Quest For Justice, Jean R. Sternlight Jan 2009

Dispute Resolution And The Quest For Justice, Jean R. Sternlight

Scholarly Works

During and since the 1976 Pound conference, the rise of nonlitigation approaches has sparked an intense debate as to whether negotiation, mediation, and arbitration are consistent with justice or rule of law, and whether litigation itself is sufficiently accessible to support a quest for justice. This article offers observations on questions related to this debate, including whether procedure matters, the limits of procedural reform, whether some processes are more just than others, and how procedural reforms enhance justice.

Why The Old Traditions Will Not Fail: Landscape, Legends, And The Construction Of Place At Dartmouth College, Charles H. Wade Jan 2009

Why The Old Traditions Will Not Fail: Landscape, Legends, And The Construction Of Place At Dartmouth College, Charles H. Wade

LSU Doctoral Dissertations

Dartmouth College, located in Hanover, New Hampshire, is one of the nine Colonial Colleges and a member of the exclusive Ivy League. Congregationalist minister Eleazar Wheelock founded Dartmouth in 1769 on the premise of training missionaries to Christianize the Indians of the region and, over the years, Dartmouth developed into a premier college. Dartmouth is famous for its traditions, its ardently loyal alumni, and as a classic New England liberal arts college. But this image does not correspond with a closer, more critical look at the College. Through both archival and ethnographic research, this dissertation examines the cultural landscape, folklore, …

Experimental Design, Synthesis And Application Of Molecular Micelle Modified Polymeric Nanoparticles For Drug Delivery Systems And Free Radical Detection, Gabriela M. Ganea Visser Jan 2009

Experimental Design, Synthesis And Application Of Molecular Micelle Modified Polymeric Nanoparticles For Drug Delivery Systems And Free Radical Detection, Gabriela M. Ganea Visser

LSU Doctoral Dissertations

Biodegradable and biocompatible polymeric nanoparticles such as poly (lactide-co-glycolide) (PLGA) nanoparticles have been extensively studied as drug delivery systems for a variety of pharmaceutical agents. Nanoparticle surface properties are primarily determined by the emulsifiers used in the synthesis process, which have a significant impact on nanoparticle physico-chemical and biological properties. Anionic amino acid – based molecular micelles were used in the emulsification process to prepare monodisperse, small (below 100 nm) PLGA nanoparticles with a well defined spherical shape. Such molecular micelle – modified nanoparticles were used as drug carriers for delivery of antioxidants. Thymoquinone is a natural antioxidant, and an …

Integrated Technology: Does It Affect Learner Outcomes?, Adam Ross Barrett Jan 2009

Integrated Technology: Does It Affect Learner Outcomes?, Adam Ross Barrett

LSU Master's Theses

Because technology has become prevalent in classrooms, this study was undertaken to test whether the use of integrated technology, specifically computers and online activities, affects learner outcomes in a classroom setting. The outcomes from classes taught using integrated technology were compared to classes taught with traditional teaching strategies. Students in a 7th grade life-science class were given pre-tests and post-tests to determine their learning gains on the topics of genetics and photosynthesis. Each class was assigned different activities based on the subject. Each unit was covered in four 90 minute periods. When one set of classes was using integrated technology …

Generation Of Novel Pikromycin Antibiotic Products Through Mutasynthesis, Shuchi Gupta, Venkatraman Lakshmanan, Beom Seok Kim, Robert Fecik, Kevin A. Reynolds Jan 2009

Generation Of Novel Pikromycin Antibiotic Products Through Mutasynthesis, Shuchi Gupta, Venkatraman Lakshmanan, Beom Seok Kim, Robert Fecik, Kevin A. Reynolds

Chemistry Faculty Publications and Presentations

Mutasynthesis in pikromycin PKS: The amenability of pikromycin polyketide synthase to mutational biosynthesis has been demonstrated. A natural triketide and its analogues, activated as N-acetyl-cysteamine thioesters, were synthesized and fed to a pikAI-deleted strain; this led to the production of new antibiotics. A vinyl analogue was found to have better antibacterial activity than pikromycin.

Substituted Bis(Beta-Diketones) For Molecular Squares, Jace Sandifer Jan 2009

Substituted Bis(Beta-Diketones) For Molecular Squares, Jace Sandifer

LSU Master's Theses

Our group has been synthesizing porous supramolecular metal-organic molecules using multidentate β-diketones as ligands. For example, m-phenylenebis(acetylacetone) (m-pbaH2, 1) and m-phenylenebis(dipropionylmethane) (m-pbprH2, 2) were readily converted to the molecular squares Cu4(m-pba)4 (6) and Cu4(m-pbpr)4 (7), which bind guests such as 4,4’-bpy and C60.1 However, 6 and 7 are only soluble in a few solvents, limiting their use in practical applications. It is therefore necessary to derivatize the ligand with different functional groups in order to improve solubility and adjust host-guest properties. Simple alkoxy derivatives should prove useful in testing this idea as they would be relatively chemically inert and should …

Bacterial Characterization Of Louisiana Groundwater Contaminated By Dnapl-Containing Chloroethanes And Other Solvents, Kimberly Bowman Jan 2009

Bacterial Characterization Of Louisiana Groundwater Contaminated By Dnapl-Containing Chloroethanes And Other Solvents, Kimberly Bowman

LSU Doctoral Dissertations

In support of an effort to determine the feasibility of using an in-situ bioremediation strategy for cleanup of groundwater in an area containing chlorinated solvents present as a dense non-aqueous phase liquid (DNAPL), the bacterial population in the groundwater at a Superfund site located near Baton Rouge, Louisiana was characterized. More than 3¡Á107 cells/mL in the groundwater were observed via microscopy. Universal bacterial and ¡°Dehalococcoides¡±-specific 16S rRNA gene libraries were constructed and analyzed. Universal clones grouped into 18 operational taxonomic units (OTUs), as defined by sequence similarity ¡Ý97.0%, which included several as yet undescribed organisms. Multiple unique sequences closely related …

Antiviral Chemotherapeutic Agents Against Equine Herpesvirus Type 1: The Mechanism Of Antiviral Effects Of Porphyrin Derivatives, Galena V. Rybachuk Jan 2009

Antiviral Chemotherapeutic Agents Against Equine Herpesvirus Type 1: The Mechanism Of Antiviral Effects Of Porphyrin Derivatives, Galena V. Rybachuk

LSU Doctoral Dissertations

Equine Herpesvirus-1 (EHV-1) is an important ubiquitous enzootic equine pathogen, causing significant economic losses to the horse industry. Despite extensive vaccination protocols, EHV-1 continues to be a major cause of epidemic abortion, perinatal mortality, respiratory disease and neurologic disease. EHV-1 infections are usually dealt with by using management practices that limit spread of the disease and secondary complications, providing symptomatic relief to infected horses, but no specific treatment is available. New therapeutic or virucidal agents could have great utility in slowing both the progression and spread of the disease in an epidemic situation. A number of porphyrins and their derivatives …

Strangers In The Postcolonial World, Thomas F. Halloran Jan 2009

Strangers In The Postcolonial World, Thomas F. Halloran

LSU Doctoral Dissertations

This dissertation analyzes American writing from and about the former British and French colonies in order to critique postcolonial theory and also to establish a new genre of expatriate literature. Focusing on the works of J. P. Donleavy, Edith Wharton, Paul Bowles, and Paul Theroux, I argue that reading these Americans disrupts the binary concepts encouraged by postcolonial theory. This project rethinks important dichotomies such as colonizer/colonized, center/margin, metropolis/margin, civilized/primitive, and white/non-white by examining the ambiguous American character in the postcolonial context. I argue that by categorizing the themes of American literature in the colonies, and analyzing the similarities and …

Insights Into The Streptomycete Conjugation Mechanism And Interstrain Inhibitor Production By The Sweet Potato Pathogen Streptomyces Ipomoeae, Jing Wang Jan 2009

Insights Into The Streptomycete Conjugation Mechanism And Interstrain Inhibitor Production By The Sweet Potato Pathogen Streptomyces Ipomoeae, Jing Wang

LSU Doctoral Dissertations

Conjugation in Streptomyces invokes a unique mechanism involving few plasmid-encoded loci. Transfer of circular plasmid pIJ101 requires only a tra gene, and a cis-acting locus clt. Here, I investigated whether the transfer genes of pIJ101 could promote transfer of a linear plasmid. While pIJ101 Tra could transfer circularized versions of the linear plasmid containing clt, the linear plasmid itself could not be transferred efficiently by Tra. All plasmids isolated from transconjugants appeared to be circular regardless of the configuration of the plasmid in the initial donor cells. However the linear plasmid could be transferred in linear form from JW1, which …

Characterization Of The 'Glutamate Effect' On The Solution Thermodynamics And Function Of The Large Fragments Of The Type I Dna Polymerases From E.Coli And T.Aquaticus, Daniel J. Deredge Jan 2009

Characterization Of The 'Glutamate Effect' On The Solution Thermodynamics And Function Of The Large Fragments Of The Type I Dna Polymerases From E.Coli And T.Aquaticus, Daniel J. Deredge

LSU Doctoral Dissertations

In this study, it is shown that the large fragments of the type I DNA polymerase from E.coli (Klenow) and T.aquaticus (Klentaq) display enhanced DNA binding affinity in glutamate vs. chloride. Across the relatively narrow salt concentration ranges often used to obtain salt linkage data, Klenow also displays an apparently decreased linked ion released (¦¤nions) in Kglutamate vs. KCl while Klentaq does not display such an effect. The osmotic stress technique reveals that Klenow and Klentaq DNA binding is associated with the release of ~500 to 600 waters in KCl. For both proteins, replacing chloride with glutamate results …

Hillary Clinton, Sarah Palin, And Michelle Obama: Performing Gender, Race, And Class On The Campaign Trail, Ann C. Mcginley Jan 2009

Hillary Clinton, Sarah Palin, And Michelle Obama: Performing Gender, Race, And Class On The Campaign Trail, Ann C. Mcginley

Scholarly Works

The 2008 Presidential campaign highlighted three strong, interesting, and very different women -- Hillary Clinton, Sarah Palin, and Michelle Obama -- who negotiated identity performances in the political limelight. Because of their diverse backgrounds, experience, and ages, an examination of how these three women performed their identities and the public response to them offers a rich understanding of the changing nature of gender, gender roles, age, sexuality and race in our culture. This essay suggests that optimism that Obama's race and gender performances may have removed the stigma from "the feminine" may be misplaced, at least when it comes to …

Media Misinterpretation, James Naples Jan 2009

Media Misinterpretation, James Naples

Quill & Scope

There have been a great number of news articles that focus on clinical health issues that manifest themselves as a result of a faulty genome. The media's interpretation and translation of scientific research aimed at understanding the human genome may be inappropriately presented to the lay public. In its presentation the media seems to have created a public that is unwilling to accept responsibility for their personal health, particularly in regards to the diagnosis of ADHD and obesity. This article explores the ramifications of media influence on public perception of these two diseases.

Bush's Legacy, April Tantillo Jan 2009

Bush's Legacy, April Tantillo

Quill & Scope

While former President George W. Bush's historical legacy is still being hotly debated, a clear bright spot is often overlooked. The President's Emergency Plan for AIDS Relief (PEPFAR) paid for antiretroviral medications for 1.4 million patients in Africa and the Caribbean compared to only 50,000 before the program. The program is far from perfect. An important criticism of PEPFAR is that the program is too restrictive. For example, one third of the money for prevention must go to abstinence only sexual education. The harm that is done to women and children by suggesting that they have the autonomy to insist …

Optimising The Synthesis And Red–Green–Blue Emission Of A Simple Organic Dye, Martha Sibrian-Vazquez, Robert M. Strongin Jan 2009

Optimising The Synthesis And Red–Green–Blue Emission Of A Simple Organic Dye, Martha Sibrian-Vazquez, Robert M. Strongin

Chemistry Faculty Publications and Presentations

Synthetic dyes have been widely used in supramolecular chemistry not only to probe fundamental chemical interactions but also as components of functional materials. Most current efforts in this regard are directed at designing new host systems for the dyes. Herein we report on the study of a versatile new organic fluorophore. We describe a synthesis which affords improved yields in a convenient one pot procedure. Moreover, a simple method for predicting and controlling the dye’s responses to external stimuli affords a potentially practical method for achieving red–green–blue and concomitant white light generation.

Chief William's Ghost: The Problematic Persistence Of The Duty To Sit Doctrine, Jeffrey W. Stempel Jan 2009

Chief William's Ghost: The Problematic Persistence Of The Duty To Sit Doctrine, Jeffrey W. Stempel

Scholarly Works

The duty to sit concept or “doctrine”—or at least what I term the “pernicious” version of the concept—emphasizes a judge's obligation to hear and decide cases unless there is a compelling ground for disqualification and creates a situation in which judges are erroneously pushed to resolve close disqualification issues against recusal when the presumption should run in exactly the opposite direction. In close cases, judges should err on the side of recusal in order to enhance public confidence in the judiciary and to ensure that subtle, subconscious, or hard-to-prove bias, prejudice, or partiality does not influence decision-making. The pernicious version …

Playing Forty Questions: Responding To Justice Roberts' Concerns In Caperton And Some Tentative Answers About Operationalizing Judicial Recusal And Due Process, Jeffrey W. Stempel

Scholarly Works

The Chief Justice of the United States would probably have excelled as a negative debater in high school forensics competitions. Good negative debaters are, as my high school English teacher put it, “great point-pickers” in that they frequently challenge affirmative proposals with a series of “what if?” or “how about?” or “what would you do if?” questions designed to leave the affirmative resolution bleeding to death of a thousand cuts. Less charitable observers might call it nit-picking. After reading Chief Justice Roberts's dissenting opinion in Caperton v. A.T. Massey Coal Co., one can easily imagine him as a high school …

Nitric Oxide Cytotoxicity And Functions Of Iron-Sulfur Enzymes In Escherichia Coli, Binbin Ren Jan 2009

Nitric Oxide Cytotoxicity And Functions Of Iron-Sulfur Enzymes In Escherichia Coli, Binbin Ren

LSU Doctoral Dissertations

Iron-sulfur proteins are ubiquitous in biological processes. Here we report that NO, a physiological free radical, can effectively inhibit cell growth of Escherichia coli in minimal medium under anaerobic growth conditions. Fractionation of the cell extracts obtained from NO-exposed cells shows a broad distribution of the protein-bound dinitrosyl-iron complexes (DNICs) formed by NO. On the other hand, the cell growth of E. coli can be restored when NO-exposed cells are either supplemented with the branched-chain amino acids (BCAAs) anaerobically or returned to aerobic growth conditions. It turns out that dihydroxyacid dehydratase (IlvD), an iron-sulfur enzyme essential for the BCAAs biosynthesis, …

Tnf-Alpha Inhibition Of Adiponectin Expression By Targeting Ppar-Gamma And C/Ebp In Adipocytes, Yanning Wang Jan 2009

Tnf-Alpha Inhibition Of Adiponectin Expression By Targeting Ppar-Gamma And C/Ebp In Adipocytes, Yanning Wang

LSU Master's Theses

Chronic inflammation is involved in the adipose tissue dysfunction through regulation of endocrine and storage function of adipocytes. As a representative proinflammatory cytokine, TNF-α was reported to inhibit expression of adiponectin. However, the mechanism of inhibition remains to be identified. Here, we provide experimental evidence that TNF-α inhibits adiponectin at both transcriptional and posttranscriptional levels. In three animal models (aP2-P65, ob/ob and high fat diets-fed mice), an increase in TNF-α expression was associated with a decrease in adiponectin expression. In 3T3-L1 adipocytes, TNF-α inhibition of adiponectin was observed at mRNA and protein levels. Luciferase reporter assay and mRNA stability tests …

Methods And Design Issues For Next Generation Network-Aware Applications, Andrei Hutanu Jan 2009

Methods And Design Issues For Next Generation Network-Aware Applications, Andrei Hutanu

LSU Doctoral Dissertations

Networks are becoming an essential component of modern cyberinfrastructure and this work describes methods of designing distributed applications for high-speed networks to improve application scalability, performance and capabilities. As the amount of data generated by scientific applications continues to grow, to be able to handle and process it, applications should be designed to use parallel, distributed resources and high-speed networks. For scalable application design developers should move away from the current component-based approach and implement instead an integrated, non-layered architecture where applications can use specialized low-level interfaces. The main focus of this research is on interactive, collaborative visualization of large …

Beyond Mediation: Thinking The Computer Otherwise, David J. Gunkel Jan 2009

Beyond Mediation: Thinking The Computer Otherwise, David J. Gunkel

Faculty Articles, Papers, and Other Scholarship

Whatever Media Studies 2.0 involves, one thing is certain, there is a need to confront and deal with new technologies, most notably computers and computer networks. Despite the fact that the discipline has largely marginalized these innovations, there has been some effort to incorporate the computer into both the theories and practices of media studies. This has been accomplished, at least in the United States, through the development of what is now called computer-mediated communication (CMC). CMC, which effectively understands the computer as a medium of human communication, does not necessarily institute a significant paradigm shift in media studies but …

Promise Of Confidentiality In Mediation: Practitioners' Perceptions, The, T. Noble Foster, Selden Prentice Jan 2009

Promise Of Confidentiality In Mediation: Practitioners' Perceptions, The, T. Noble Foster, Selden Prentice

Journal of Dispute Resolution

In response to these articles, we sought to determine the perceptions of mediation practitioners in our own region, the Seattle/King County area, regarding mediation confidentiality and privilege. This paper presents our finding and addresses the following: (1) the scope of confidentiality and privilege under Washington law; (2) recent Washington case law addressing evidence of mediation communications; (3) a review of Florida's recent legislation - significantly different from Washington law, and unique among state mediation statutes - which provides for sanctions in the event confidentiality is breached; and (4) the perceptions of mediators, attorneys, and judges from the greater Seattle area …

I Lost My Home, Don't Take My Voice: Ensuring The Voting Rights Of The Homeless Through Negotiated Rulemaking, Sarah Devlin

Journal of Dispute Resolution

"The right to vote, as the citizen's link to his laws as government, is protective of all fundamental rights as privileges." This right is often unexercised or taken for granted; but for hundreds of thousands of homeless citizens, voting is a right which is beyond reach. The U.S. Department of Housing and Urban Development estimated that on any given night in 2005, more than 754,000 Americans were without a traditional residence--living in emergency shelters, transitional housing, or on the streets. While many of those people are only temporarily homeless, many others are being disenfranchised by an electoral system that requires …

Future Of Mediation: A Sociological Perspective, The, Brian Jarrett

Journal of Dispute Resolution

Arguably, these sociological pressures are central to the future direction of the mediation field and, in the aggregate, provide a useful building block in the development of an emerging sociology of mediation-a development that could fill the theory-to-practice gap which currently bedevils the mediation field. Understanding sociological forces reminds us of the constraints within which mediators, as social actors, must work. More importantly, an awareness of these pressures is, conceivably, essential to the development of an autonomous and discernible profession that remains capable of welcoming a diversity of practitioners and their respective approaches. I summarize each of these pressures below …

When It's So Hard To Relate: Can The Legal System Mitigate The Trauma Of Victim-Offender Relationships?, Jody L. Madeira Jan 2009

When It's So Hard To Relate: Can The Legal System Mitigate The Trauma Of Victim-Offender Relationships?, Jody L. Madeira

Articles by Maurer Faculty

This article argues that, in the aftermath of violent crime, a relationship that is both negative and involuntary can form between crime victims and offenders. This relationship fetters the victim to the crime and the criminal, rendering it difficult to recover from the transgression. To illustrate how such a relationship may form and what consequences it may have for victims, this article uses the Oklahoma City bombing as a case study, documenting through the use of original interviews an involuntary relationship in which victims' family members and survivors perceived they were tethered to Timothy McVeigh. This perceived relationship with McVeigh …

Judicial Activism And Fourteenth Amendment Privacy Claims: The Allure Of Originalism And The Unappreciated Promise Of Constrained Nonoriginalism, Daniel O. Conkle Jan 2009

Judicial Activism And Fourteenth Amendment Privacy Claims: The Allure Of Originalism And The Unappreciated Promise Of Constrained Nonoriginalism, Daniel O. Conkle

Articles by Maurer Faculty

Among other meanings, "judicial activism" can be defined as judicial decisionmaking that frustrates majoritarian self-government and that is unconstrained by law. So understood, judicial activism is presumptively problematic, because it frustrates customary democratic and judicial norms.

In this essay, I address originalist and nonoriginalist responses to the presumptive problem of judicial activism in the context of Fourteenth Amendment privacy claims, including claims relating to abortion, sexual conduct, and same-sex marriage. I argue that originalism is an overrated solution, largely because current understandings of originalism, despite claims to the contrary, do not provide standards of decision that are sufficiently clear to …
