Isolation And Characterization Of A Rhodobacter Capsulatus Hemc Mutant., Karen Coleman Sullivan
Isolation And Characterization Of A Rhodobacter Capsulatus Hemc Mutant., Karen Coleman Sullivan
LSU Historical Dissertations and Theses
Rhodobacter capsulatus, a purple, nonsulfur photosynthetic bacterium, uses the tetrapyrrole pathway to synthesize four end products: heme, bacteriochlorophyll, vitamin B12, and siroheme. This laboratory has focused on the regulation of the common pathway leading from aminolevulinate to protoporphyrin IX in R. capsulatus. The common portion of the pathway is regulated up to 100-fold by changes in oxygen tension. Research on the regulation of this pathway has been hampered due to a lack of mutants. Until now, the only mutants isolated which block heme production are hemA mutants, which lack aminolevulinate synthase. Since R. capsulatus lacks a cytochrome-independent growth mechanism, mutations …
Cultural Preservation In The Romansh Landscape: A Geography Of The Swiss -Romansh Movement., Erik George Prout
Cultural Preservation In The Romansh Landscape: A Geography Of The Swiss -Romansh Movement., Erik George Prout
LSU Historical Dissertations and Theses
The research explores the cultural landscape of Romansh speakers in Switzerland. The fundamental question is whether small ethno-linguistic groups can create and protect a place (earthly and poetic) for their language to flourish. Swiss-Romansh have many advantages because of their political stability and economic prosperity. Their efforts in promoting and protecting the Romansh language offer a possible model for other culture groups. The research elucidates four distinct geographic scales: national (Switzerland's multilingual federalism), regional (alpine canton of Grischun/Graubunden), local Romansh villages (vinscnanca or communes), and an imaginary Rhactian ethnicity. I employ the term cultural preservation to discuss the Romansh situation. …
Mapping Enredos Of Complex Spaces. A Regional Geography Of Olancho, Honduras., Mark Andrew Bonta
Mapping Enredos Of Complex Spaces. A Regional Geography Of Olancho, Honduras., Mark Andrew Bonta
LSU Historical Dissertations and Theses
This dissertation is a regional geography of the department of Olancho in northeastern Honduras. It focuses on the enredos (entangled situations) that characterize geographic reality, particularly in the interlocked domains of nation-state priorities, local identities, rain forest conservation, and sustainable development. The overarching theoretical framework of this dissertation is the collaborative work of complexity theorists Gilles Deleuze and Felix Guattari. The major theme running through "Mapping Enredos" is the multidimensional nature of spatiality (complex spaces), ground for human and non-human existence as well as source of endless conflicts. Fieldwork was undertaken from 1999 to 2000. Qualitative research methods employed include …

Resorcinol Condensation Products: A New Class Of Colorimetric Sensors For Saccharides., Claude Joseph Davis
LSU Historical Dissertations and Theses
Resorcinarenes are a unique class of cyclic aromatic tetramers that have been known for over a century. In our laboratories, we have reported the first synthesis, isolation, and characterization of resorcinarenes with arylboronic acid functionality their framework. The physical property studies of our new resorcinarene series resulted in covalent and non-covalent binding studies, which revealed the first evidence chair (c2h) resorcinarenes can compete effectively with their crown (c4v ) counterparts the binding of polar guests (i.e. carbohydrates). In addition, the chiral tetraarylboronate octols have demonstrated potential utility as substrates for stereoselective extractions carbohydrates. A facile method for detecting and monitoring …
Molding Large Area Plastic Parts Covered With Harms., Mircea Stefan Despa
Molding Large Area Plastic Parts Covered With Harms., Mircea Stefan Despa
LSU Historical Dissertations and Theses
Injection molding and hot embossing proved to be suitable for use to reproduce layouts of micropatterns manufactured by LIGA. The research work was based on two commercially available machines. Preliminary experiments with both machines indicated that several modifications and additions were necessary to adapt the injection machine and the embossing press for microreplication. For the injection machine, a mold geometry was designed to ensure minimal pressure loss upstream from the entrance into the mold cavity, and optimal shape for molding and demolding. For the hot embossing press, a vacuum chamber was designed containing the embossing sandwich, with the temperatures of …
Electronic Communication Channels In Franchise Organizations., Michael Hebert Dickey
Electronic Communication Channels In Franchise Organizations., Michael Hebert Dickey
LSU Historical Dissertations and Theses
The virtual organization has emerged as a result of the availability of information technology. One business model well suited to the virtual form is franchising. Since the success of franchise organizations is highly dependent on communication effectiveness, these organizations are beginning to adopt technology---namely, private corporate networks called intranets and extranets---to support electronic communication. This research study examines the effects of electronic communication channels on communication patterns within franchise organizations. First, the study addresses how electronic communication channels affect communication frequency within the franchise organization. Second, the effect of electronic communication channels on strategic outcomes, specifically, innovation, franchisee satisfaction, and …
Language And Power In A Louisiana Murder Trial: Discourse Features In Witness Testimony., Kara Lynn Gibson
Language And Power In A Louisiana Murder Trial: Discourse Features In Witness Testimony., Kara Lynn Gibson
LSU Historical Dissertations and Theses
The literature concerning language, law, and power has traditionally focused on the linguistic strategies legal professionals employ for the purpose of controlling the speech of their clients and/or witnesses. However, newer research, stemming from gender-based theories of how power and/or powerlessness is manifest in language, promotes linguistic analyses from the perspective of the disempowered as opposed to the empowered, Such studies claim that speakers' election or avoidance of certain discourse features (e.g., hedges, hypercorrect forms, polite address forms, overlap, quotatives and gestures, etc.) and responses-types (e.g., declarative-context questions, copy responses, fragmented versus narrative responses, etc.) reflects their perceived power as …
Synthetic Peptides: Design, Structure And Biological Function., Lars Gustav Johan Hammarstrom
Synthetic Peptides: Design, Structure And Biological Function., Lars Gustav Johan Hammarstrom
LSU Historical Dissertations and Theses
The synthesis of a series of polyfunctional Calpha,C alpha-disubstituted glycines is described. The lysine-like amino acid analog, Api, was prepared by regioselective hydrolysis of a triBoced hydantoin, followed by Nalpha-protection to yield the first orthogonally protected ionizable Calpha,Calpha-disubstituted amino acid which is alicyclic. The synthesis of three orthogonally protected tetrafunctional amino acids, Bap, Bglu, and Basp was envisioned by alkylation of the organic synthon ethyl nitroacetate. Subsequent regioselective modification should allow for the isolation of the first tetrafunctional amino acid derivatives suitable for solid-phase synthesis. These amino acids are designed to induce peptide secondary structure by salt-bridge stabilization. A series …
Analysis Of Hydrocarbon Materials By Use Of Nonpolar Matrices In Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry (Maldi-Ms)., Stephen Francis Macha
Analysis Of Hydrocarbon Materials By Use Of Nonpolar Matrices In Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry (Maldi-Ms)., Stephen Francis Macha
LSU Historical Dissertations and Theses
In this study, polyaromatic hydrocarbon compounds including anthracene, pyrene, acenaphthene and perylene were investigated as nonpolar matrices in matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the analysis of selected nonpolar analytes. First, the influence of matrix and the analyte ionization potentials on a charge-transfer ionization mechanism were determined. Results of these studies demonstrated that formation of radical molecular cations in MALDI-MS depends on the ionization energy difference between the matrix and the analyte. Charge-transfer ionization occurs only when the ionization potential of the matrix is higher than that of the analyte. Next, nonpolar matrices were investigated for the analysis of …
Synthesis Of Phosphonopeptides And Alpha, Alpha-Dialkylated Amino Acid-Rich Peptides., Sheila Denise Rushing
Synthesis Of Phosphonopeptides And Alpha, Alpha-Dialkylated Amino Acid-Rich Peptides., Sheila Denise Rushing
LSU Historical Dissertations and Theses
Peptides and peptide analogs are central to the understanding of biological and biochemical phenomena as well as in the development of new pharmaceutical agents. This research encompasses two classes of peptide mimetics: phosphonopeptides and short, amphipathic peptides rich in alpha,alpha-disubstituted amino acids (alphaalphaAA). The focus of the first part of the peptide analog project was on the preparation of sterically-hindered phosphonamide and thiophosphonamide dipeptides. Conditions were developed, based on our P(III) synthetic approach, for the preparation of the phosphonamide dipeptides, Cbz-CyhGly psi [P (O) (OpNb) NH] Trp-NH2 and Cbz-CyhGly psi [P (O) (OpNb) NH] Trp-OMe, which were previously unattainable by …

The purpose of this study was to explore the evolution of the legal concept of legal liability of higher education institutions for alcohol-related injuries using a theoretical framework provided by tort law. The analysis was designed to provide a greater understanding of how and why the law concerning this concept has evolved. In addition to a legal analysis, interviews were conducted with student affairs administrators at institutions participating in the Robert Wood Johnson Foundation "A Matter of Degree: Reducing High-Risk Drinking Among College Students" program. Particular attention was given to the influences identified by the student affairs administrators as catalysts …
Understanding The Connections Between High-Stakes Test Consequences And School Literacy Experiences., Deborah Karen Setliff
Understanding The Connections Between High-Stakes Test Consequences And School Literacy Experiences., Deborah Karen Setliff
LSU Historical Dissertations and Theses
The purpose of this ethnographic study was to connect the remedial summer school experiences of two fourth-grade students and four fifth-grade students with their school literacy experiences the following year. Understanding the students' experiences and connecting the experiences with school personnel provided a link between the students' and school personnel's perceptions of high-stakes testing consequences. Bridging these perceptions through cross-case analysis revealed the physical, emotional, and philosophical effects high-stakes testing is having on the students, school administrators, classroom teachers, and reading curriculum and instruction at the two elementary schools studied. Integrating the findings at the two schools helped develop a …
William Albright's Sonata For Alto Saxophone And Piano: Analytical Insights And Performance Considerations., Brian Russell Utley
William Albright's Sonata For Alto Saxophone And Piano: Analytical Insights And Performance Considerations., Brian Russell Utley
LSU Historical Dissertations and Theses
William Albright's Sonata for Alto Saxophone and Piano amply demonstrates the stylistic eclecticism for which he is famous. The four movements exhibit distinct characters and musical languages, including references to compositional practices of the past, as in the two-part invention of the first movement and the follia of the second, and allusions to American popular music, as in the bebop sections of the finale. This polystylistic compositional approach also invites a variety of analytical techniques, including investigation into form, motivic development, register, texture, and pitch usage. This study, the first of its kind on Albright's sonata, examines these characteristics in …
The Influence Of An Active Postvention On The Length Of Time Elapsed Before Survivors Of Suicide Seek Treatment., Frank Ray Campbell
The Influence Of An Active Postvention On The Length Of Time Elapsed Before Survivors Of Suicide Seek Treatment., Frank Ray Campbell
LSU Historical Dissertations and Theses
Those who are significantly impacted by the death of someone to suicide are known as survivors of suicide. This study examined two groups of suicide survivors, one group received an active postvention model (APM), and the other group received no active postvention model. The study utilized both t-test and chi-square to compare the groups based on key demographic characteristics. The study compared model of postvention (active versus passive) for the time elapsed between the suicide and the survivors seeking treatment. The two groups studied were survivors who sought treatment at a well established metropolitan crisis intervention center in the southern …
Performativity And Performance: Representing The Tattooed Body., Mindy Elaine Fenske
Performativity And Performance: Representing The Tattooed Body., Mindy Elaine Fenske
LSU Historical Dissertations and Theses
In this study I examine visual representations of tattooed bodies in three arenas of cultural production: tattoo conventions, advertising, and neo-tribal books. Through the methodological lens of genealogies of performance, I analyze these texts' construction of the tattooed body as classed, gendered, and exotic. I argue that contemporary representations of the tattooed body resist and reproduce discursive power regimes by surrogating prior cultural performances and representations of performance. I argue that contemporary visual representations of the tattooed body succeed in resisting discursive authority when they performatively cite multiple and transgressive authorities. I additionally indicate that the body in representation transgresses …
Framing And Counterframing Of The Middle East Peace Process In The Arab -Israeli Press: A Comparative Analysis Of "Assafir" And "The Jerusalem Post"., Houda Hanna El-Koussa
Framing And Counterframing Of The Middle East Peace Process In The Arab -Israeli Press: A Comparative Analysis Of "Assafir" And "The Jerusalem Post"., Houda Hanna El-Koussa
LSU Historical Dissertations and Theses
The Arabs and Israelis have been negotiating peace for the past ten years; however, the conflict still ignites with no apparent hope for any near resolution. Understanding the rhetorical construction of the peace reality may help in managing this conflict. This study examines the symbolic construction of the peace process in the Arab and Israeli press. It comparatively studies how the Arab and Israeli press, through language choice, define peace, elucidate its implications, and judge actors and actions involved in the peace process. This study identifies the metaphors used and the dominant rival frames constructed in two conflicting newspapers, Assafir …
Physicochemical, Functional And Spectroscopic Analysis Of Crawfish Chitin And Chitosan As Affected By Process Modification., Sandeep Kumar Rout
Physicochemical, Functional And Spectroscopic Analysis Of Crawfish Chitin And Chitosan As Affected By Process Modification., Sandeep Kumar Rout
LSU Historical Dissertations and Theses
Traditional isolation of chitin from crawfish shells involves three sequential steps: demineralization (DM, removing calcium carbonate/phosphate), deproteinization (DP), and decolorization (DC, removing mainly astaxanthin). The first two steps can be reversed (i.e., DMP or DPM). Chitin is converted to chitosan by deacetylation (DA). Isolation steps may be shortened, depending on intended applications of chitosan. The first study investigated effects of (1) reversing sequence and (2) eliminating DP and DC steps on physicochemical and functional properties of chitosan and conversion efficiency of chitin. Twelve different processes: DM, DP, DPM, DMP, DPMC, DMPC, DMA, DMCA, DPMA, DMPA, DPMCA, DMPCA were investigated. DA …

Identification Of The Domains Of Urer, An Arac-Like Transcriptional Regulator Of The Urease Gene Cluster In Proteus Mirabilis, Carrie A. Poore, Christopher Coker, Jonathan D. Dattelbaum, Harry L.T. Mobley
Identification Of The Domains Of Urer, An Arac-Like Transcriptional Regulator Of The Urease Gene Cluster In Proteus Mirabilis, Carrie A. Poore, Christopher Coker, Jonathan D. Dattelbaum, Harry L.T. Mobley
Chemistry Faculty Publications
Proteus mirabilis urease catalyzes the hydrolysis of urea to CO2 and NH3, resulting in urinary stone formation in individuals with complicated urinary tract infections. UreR, a member of the AraC family, activates transcription of the genes encoding urease enzyme subunits and accessory proteins, ureDABCEFG, as well as its own transcription in the presence of urea. Based on sequence homology with AraC, we hypothesized that UreR contains both a dimerization domain and a DNA-binding domain. A translational fusion of the leucine zipper dimerization domain (amino acids 302 to 350) of C/EBP and the C-terminal half of UreR …
