Cloning, Sequencing And Regulation Of The Rhodobacter Capsulatus Hemh Gene., Ekaterina Vladislavova Kanazireva Jan 1997

Cloning, Sequencing And Regulation Of The Rhodobacter Capsulatus Hemh Gene., Ekaterina Vladislavova Kanazireva

LSU Historical Dissertations and Theses

Rhodobacter capsulatus, a purple non-sulfur photosynthetic bacterium, synthesizes four tetrapyrrole end products: heme, bacteriochlorophyll, siroheme and vitamin B$\sb{12}$ via the common tetrapyrrole biosynthetic pathway. The biosynthesis of tetrapyrroles in R. capsulatus is a complex and precisely controlled process which has been under extensive investigation. In order to study the regulation of tetrapyrrole biosynthesis, the R. capsulatus hemH gene was cloned by complementation of an E. coli $\Delta hemH$ mutant and sequenced. The enzyme ferrochelatase, encoded by the hemH gene, catalyzes the insertion of ferrous iron into protoporphyrin IX, thus producing heme. The consensus ferrochelatase signature sequence was found in the …

Gravity-Assisted Tertiary Gas Injection Process In Water-Drive Oil Reservoirs., Bogdan Lepski Jan 1997

Gravity-Assisted Tertiary Gas Injection Process In Water-Drive Oil Reservoirs., Bogdan Lepski

LSU Historical Dissertations and Theses

In dipping, water-drive reservoirs, substantial incremental oil can be produced using gravity-assisted gas injection improved recovery processes. These processes include the Double Displacement Process (DDP) and the Second-Contact Water Displacement (SCWD). The efficiency of these processes depends, in part, on phase distribution in the pore space after gas injection which in turn depends on interfacial and surface tensions (IFT) of the phases involved. The research described here-in pertains to experimental work performed to investigate various aspects of the DDP and the SCWD in both homogenous and heterogeneous rock types with dead oil/nitrogen and recombined-oil/methane fluid systems. Additional work was performed …

Structure-Activity Relationships Of Nitroarenes: Mutagenicity, Oxygen Consumption, Toxicity, And Xenobiotic Radical Production., Caroline Ann Metosh-Dickey Jan 1997

Structure-Activity Relationships Of Nitroarenes: Mutagenicity, Oxygen Consumption, Toxicity, And Xenobiotic Radical Production., Caroline Ann Metosh-Dickey

LSU Historical Dissertations and Theses

The nitroreduction of 4NQO and five structural analogs were studied with respect to radical production and mutagenicity. In the umu assay, 4NQO was the most mutagenic analog. Addition of microsomal and cytosolic protein from induced and uninduced rat liver samples decreased 4NQO mutagenicity in the standard strain (Salmonella typhimurium TA 1535/psk1002) 4NQO mutagenicity was also found to be decreased in the nitroreductase-deficient strain (Salmonella typhimurium TA1535NR/psk1002). In several strains of the Protox$\rm\sp{TM}$ assay 4NQO yielded the highest induction rate as compared to other compounds tested. In the presence of ascorbate 4NQO cytotoxicity, but not mutagenicity, was substantially enhanced. Oxygen consumption …

Development And In Vivo Evaluation Of A Pura Mutant Strain Of The Channel Catfish Pathogen Edwardsiella Ictaluri., Mark Lee Lawrence

LSU Historical Dissertations and Theses

Edwardsiella ictaluri is the causative agent of enteric septicemia of catfish (ESC), which is the most serious disease affecting the channel catfish industry. Killed vaccines have been inconsistent in providing protection against ESC, and no live attenuated vaccines have been described. The purpose of this study was to develop a nutritionally attenuated mutant strain of E. ictaluri and evaluate its virulence and vaccine efficacy. An E. ictaluri genomic library was constructed, and a clone containing the purA gene was isolated and sequenced. The E. ictaluri purA gene was found to have several features in common with the E. coli purA …

Global Experimental Effects Of Country Of Origin And Product Type On The Structural Parameters Of A Purchase Intentions Model., Ruth L. Lumb Jan 1997

Global Experimental Effects Of Country Of Origin And Product Type On The Structural Parameters Of A Purchase Intentions Model., Ruth L. Lumb

LSU Historical Dissertations and Theses

An empirical assessment of the overall effects of country of origin and product type on the structural parameters of a purchase intentions model is undertaken. First, it is theorized that (1) product involvement, (2) perceived risk, (3) psychic distance, (4) perceived product quality, and (5) national character will directly or indirectly affect purchase intentions of imported goods. These constructs form the operational framework for purchase intentions of foreign-made products, which is presented in the form of a structural equation model. Secondly, it is proposed that country of origin and product type may be viewed as global experimental variables, thereby having …

Visualizing Autobiography: Intersections Of Gender, Representation, Curriculum Theory., Anne Elizabeth Pautz Jan 1997

Visualizing Autobiography: Intersections Of Gender, Representation, Curriculum Theory., Anne Elizabeth Pautz

LSU Historical Dissertations and Theses

Defined by customs of femininity, women who transcend those definitions find it difficult to represent themselves in a comprehensible manner. The contradictions between the actual activities of life and the demands of femininity require woman to adopt unique approaches to self-representation in order to be accepted. Tied to the biological functions of their bodies through images in the media and social institutions, as well as their internalized images, women often find trying to represent themselves beyond or against their body problematic. The female body is presented as controller of destiny, both through beauty and motherhood requirements. Women often create representations …

The Florida Chautauqua As Text: Creating And Satisfying A Disposition To Appropriate Cultural Goods In Northwest Florida., Matthew Albert Beemer Jan 1997

The Florida Chautauqua As Text: Creating And Satisfying A Disposition To Appropriate Cultural Goods In Northwest Florida., Matthew Albert Beemer

LSU Historical Dissertations and Theses

The purpose of this dissertation is to demonstrate that the Florida Chautauqua in De Funiak Springs, Florida, was primarily a commercial venture which pretended to a goal of offering cultural, educational, and religious products. In the Chautauqua's early years, it succeeded because it could exploit the economic and cultural situation. The Assembly tried to create a market for "culture" by developing cultural competencies in potential consumers so that those consumers would "buy" what the Chautauqua could sell. As the situation changed, the Florida Chautauqua, though it tried, could not adapt enough to be viable. To support the argument, I describe …

Syntheses, Separations, And Applications Of Water-Soluble Chiral Calixarenes., Yuling Zhang Jan 1997

Syntheses, Separations, And Applications Of Water-Soluble Chiral Calixarenes., Yuling Zhang

LSU Historical Dissertations and Theses

This dissertation focuses on the study of water-soluble calixarene derivatives as receptors for fluorescence probes and as chiral selectors. The synthesis of sulfonated calixarenes was first pursued and a method for the separation of sulfonated calixarenes (4), (6), (8) and the 4-hydroxylbenzene sulfonate monomer by capillary zone electrophoresis with direct UV absorbance detection is described. Fluorescence and absorption studies of water-soluble sulfonated calix(6)arene (SCX6) are reported. A red shift in the absorption spectrum and a change in the fluorescence spectrum of the calixarenes are observed upon an increase in pH from 2.0 to 13.0. The spectroscopic changes are attributed to …

Stochastic Techniques For The Solution Of Electrostatic Problems With Applications To Electron Optics., Elias Kougianos Jan 1997

Stochastic Techniques For The Solution Of Electrostatic Problems With Applications To Electron Optics., Elias Kougianos

LSU Historical Dissertations and Theses

We apply stochastic techniques towards the solution of the two-dimensional Laplace's equation in boundary value problems encountered in the calculation of electrostatic potentials in electron lenses and deflectors. The justification of these techniques arises from an astonishingly simple but far-reaching principle, which has been known for a long time but has been rarely used: the potential at any point in the interior of a charge-free region can be calculated by performing random walks starting at this point and terminating at the boundary of the region--the potential is then the average of the potential boundary values (assumed known) over the random …

A Study Of The Effect Of Energetic Flux Bombardment On Intensified Plasma-Assisted Processing., Albert Amatey Adjaottor Jan 1997

A Study Of The Effect Of Energetic Flux Bombardment On Intensified Plasma-Assisted Processing., Albert Amatey Adjaottor

LSU Historical Dissertations and Theses

An investigation of the plasma nitriding mechanism under intensified conditions (average particle energy up to 1200 eV) was carried out using a triode configuration. The significance of the different physical processes taking place during intensified plasma nitriding, such as sputtering, implantation, defect generation, redeposition and diffusion were investigated experimentally, while theoretical predictions were obtained by using the TRIM (transport of ions in matter) code. A titanium-base alloy was selected as the substrate material. Sputtering yield in an inert atmosphere was found to exhibit three regimes as a function of incoming particle energy. The low energy and high energy regimes were …

Design And Analysis Of Optical Interconnection Networks For Parallel Computation., Yueming Li Jan 1997

Design And Analysis Of Optical Interconnection Networks For Parallel Computation., Yueming Li

LSU Historical Dissertations and Theses

In this doctoral research, we propose several novel protocols and topologies for the interconnection of massively parallel processors. These new technologies achieve considerable improvements in system performance and structure simplicity. Currently, synchronous protocols are used in optical TDM buses. The major disadvantage of a synchronous protocol is the waste of packet slots. To offset this inherent drawback of synchronous TDM, a pipelined asynchronous TDM optical bus is proposed. The simulation results show that the performance of the proposed bus is significantly better than that of known pipelined synchronous TDM optical buses. Practically, the computation power of the plain TDM protocol …

Tickets To His Head: Larry Gelbart (1928-) As Writer And Adaptor., Jules Adolphe Malarcher Iii Jan 1997

Tickets To His Head: Larry Gelbart (1928-) As Writer And Adaptor., Jules Adolphe Malarcher Iii

LSU Historical Dissertations and Theses

Larry Gelbart (1928-) has dominated the field of comedy writing in the latter half of the twentieth century the way George S. Kaufman (1889-1961) dominated the first half. Comedy, according to Gelbart, is a "tic--a way of making myself comfortable. I can't imagine not having comedy to lean on. I tend to write things with a circus-like atmosphere. In my mind, there's a circus--three rings--all the time.". The three comedy rings in his head may be classified according to the areas where his unique talents especially emerge: (1) talent to adapt comedy from one medium to another, or from one …

Educational Plans Of Community College Students: An Expansion Of Two College Choice Models., Lisa M. Smith-Vosper Jan 1997

Educational Plans Of Community College Students: An Expansion Of Two College Choice Models., Lisa M. Smith-Vosper

LSU Historical Dissertations and Theses

The purpose of this study was to determine if the factors posited by previous researchers to affect predisposition to attend college in high school students also affect the predisposition to transfer in the two-year college student population, and to investigate whether or not an expansion of the Hossler and Gallagher (1987) three-phase model of college choice and the Hossler and Stage (1992) Model of High School Students' Predisposition to College would yield great benefits. This analogy uses variables that have been advanced as effectual in the predisposition stage of the college choice process on the selected student population. The problem …

Characterization Of Monomer-Containing Monolayer Films On Au Surfaces., Robert J. Willicut Jan 1997

Characterization Of Monomer-Containing Monolayer Films On Au Surfaces., Robert J. Willicut

LSU Historical Dissertations and Theses

Exploration into the nature of ultrathin, surface-confined films capable of electronic conduction has been the primary purpose of this dissertation. Specifically, the confinement of pyrrole monomer to Au surfaces through organosulfur linkages has been investigated. The synthesis of these new $\omega$-(N-pyrrolyl)alkanethiols is described herein. Cyclic voltammetry was utilized in this work to polymerize the monolayers and characterize the resulting films. Voltammetric analysis yielded currents in the correct potential region for poly(N-alkylpyrrole) charging/discharging. Other electrochemical studies revealed the ability of strong nucleophiles and electroinactive diluents to quench surface-confined polymer formation though they did not affect oxidation of the monomer. Exchange experiments …

A Feminist Study Of African American Art In New Orleans: Considerations Of Aesthetics, Art History And Art Criticism., Harriet Joanne Walker

LSU Historical Dissertations and Theses

How students are taught to think about what is considered "art" and who are "artists" contributes to their sense of self within the world. It can confine them to accept a system that devalues and excludes or it can inspire them to explore the political dimensions of art, to recognize social contradictions, and to contribute to cultural dialogue. The purpose of this study is to provide content for an art curriculum that develops the intellectual capabilities and broadens the critical consciousness of students. The study of aesthetics, art history, and art criticism offer possibilities for understanding the multiple social, historical, …
