Differential Detection Of Bartonella Species And Strains In Cat Scratch Disease Diagnostics By Polymerase Chain Reaction Amplification Of 16s Ribosomal Rna Gene, Ronald A. Tapp, Alma F. Roy, Richard E. Corstvet, Vincent L. Wilson Jan 2001

Differential Detection Of Bartonella Species And Strains In Cat Scratch Disease Diagnostics By Polymerase Chain Reaction Amplification Of 16s Ribosomal Rna Gene, Ronald A. Tapp, Alma F. Roy, Richard E. Corstvet, Vincent L. Wilson

Faculty Publications

Cat scratch disease (CSD) has been difficult to diagnose in animals because of the protracted clinical course of infection and the quiescent phases when the microbial culprit lies dormant. The causative agent in CSD appears to be multiple species and strains of Bartonella. Using polymerase chain reaction (PCR) techniques for amplification of highly variable regions of the 16S ribosomal RNA (rRNA) gene sequence, a very sensitive species- and strain-specific assay for CSD-causing Bartonella species was developed. PCR primers were designed to specifically amplify the 16S rRNA gene of Bartonella species but not of other microbial pathogens. This initial PCR was …


Monodromy Of Fiber-Type Arrangements And Orbit Configuration Spaces, Daniel C. Cohen Jan 2001

Monodromy Of Fiber-Type Arrangements And Orbit Configuration Spaces, Daniel C. Cohen

Faculty Publications

We prove similar theorems concerning the structure of bundles involving complements of fiber-type hyperplane arrangements and orbit configuration spaces. These results facilitate analysis of the fundamental groups of these spaces, which may be viewed as generalizations of the Artin pure braid group. In particular, we resolve two disparate conjectures. We show that the Whitehead group of the fundamental group of the complement of a fiber-type arrangement is trivial, as conjectured by Aravinda, Farrell, and Rouchon [AFR]. For the orbit configuration space corresponding to the natural action of a finite cyclic group on the punctured plane, we determine the structure of …

Soliton Excitations As Emitted Clusters On Nuclear Surfaces, R. A. Gherghescu, A. Ludu, J. P. Draayer Jan 2001

Soliton Excitations As Emitted Clusters On Nuclear Surfaces, R. A. Gherghescu, A. Ludu, J. P. Draayer

Faculty Publications

This work reports on calculations of the deformation energy of a nucleus for nonlinear deformations. The working hypothesis is that, beyond the usual linear approximation, the nonlinear analysis yields soliton solutions moving on its surface. The potential barrier against the emission of a soliton is calculated within the macroscopic-microscopic method. The outer turning point of the barrier determines limitations on the geometrical and kinematical parameters for the formation of a surface soliton. For large asymmetry, the two-centre shell model is used to assign a structure to the soliton. Calculations for 248No with the emission of a 40Ca soliton …

Effects Of The High -Probability Sequence With And Without Extinction In Children With Feeding Disorders., Jennifer Eileen Dawson Jan 2001

Effects Of The High -Probability Sequence With And Without Extinction In Children With Feeding Disorders., Jennifer Eileen Dawson

LSU Historical Dissertations and Theses

The effects of the high-probability instructional sequence, with and without extinction, on increasing compliance to eat in three children with severe food refusal and selectivity were evaluated. Pediatric feeding disorders, in which children refuse most or all food and drink, are a rare and life threatening problem that requires intensive treatment. The majority of behavioral techniques used with feeding disordered children manipulate the consequence of food refusal. The use of antecedent procedures in the treatment of food refusal has been limited. One antecedent technique, the high-probability instructional sequence, involves first presenting the individual with a series of instructions that he/she …

Survival Of Canine Epididymal Sperm Under Cooled And Frozen-Thawed Conditions, Karla Stilley Jan 2001

Survival Of Canine Epididymal Sperm Under Cooled And Frozen-Thawed Conditions, Karla Stilley

LSU Master's Theses

The objective of the first experiment was to determine the effects of storage at 22„aC vs. 4„aC on the motility and percentage of membrane-intact sperm (%MIS) of epididymal mouse sperm. Testicles were allocated into 22„aC or 4„aC treatment groups and stored for 24 or 48 hours. Additional testicles were allocated into the 4„aC treatment for storage for 72 or 96 hours. Sperm was collected and analyzed at each time point. Storage at 22„aC lowered motility and %MIS (P<0.05) when compared with control sperm and 4„aC sperm at both the 24 and 48 hours. Motility and %MIS of 4„aC sperm did not decrease when compared with the control until after 72 hours of storage. The second experiment evaluated the effects of 22„aC vs. 4„aC storage for 24 and 48 hours on epididymal dog sperm. Motility and %MIS of the 22„aC sperm was lower than that of the 4„aC sperm and the control (P<0.05) at 24 and 48 hours. Motility of the 4„aC sperm was lower than the control at 24 and 48 hours (P<0.05), however %MIS was not lower than the control until 48 hours. The third experiment tested the effect of cryopreservation on epididymal dog sperm. Sperm was frozen immediately (A), after 48 hours at 4„aC in liquid (B) or after 48 hours at 4„aC of the whole testicle (C). Both pre-freeze (PF) and post-thaw (PT) motility and %MIS of B and C were lower than A (P<0.05). PT values were lower than PF values in all treatments (P<0.05). PT motility of B was lower than C (0 vs. 35.0¡Ó3.6%). Storage at 4„aC allows collection of motile epididymal mouse and dog sperm for several days after death. Dog testicles can be refrigerated for 2 days and epididymal sperm frozen with PT motility and %MIS of 35 and 62%.


Near The Lewis & Clark Trail, Chad Colin Husted Jan 2001

Near The Lewis & Clark Trail, Chad Colin Husted

LSU Master's Theses

Near the Lewis & Clark Trail is a creative writing thesis that contains two distinct parts. Part one is a short story cycle: a collection of interlinked narratives that together, tell a larger, cohesive story. Many different points of view, narrative techniques, and non-linear time sequences are used in order to provide a pastiche of different voices, points in time, and perspectives, that ultimately form an overall narrative structure. In addition to the stories, there are several fictional documents that are used to separate the work at critical times, and to provide subtext. In between the stories are: a letter …


A Performer's Guide To Theatrical Elements In Selected Trombone Literature, Cason Austin Duke Jan 2001

A Performer's Guide To Theatrical Elements In Selected Trombone Literature, Cason Austin Duke

LSU Major Papers

In the last forty years, many new solo and chamber pieces have been written for the trombone which involve elements of a theatrical nature, including lighting, make-up, costume, stage direction, dialogue/narration, sound effects, props, and audience interaction. It is difficult for a trombonist searching for music to discern a piece's theatrical nature by its listing in most catalogs. This document has attempted to solve that problem by gathering pieces that share these elements into an annotated collection. Nearly 200 pieces were discovered through contacts made with individual trombonists, composers, and publishers around the world. Of these, over sixty were acquired …


Effects Of Immigrant Status On Mexicans In The United States, Michelle Monique Balan Jan 2001

Effects Of Immigrant Status On Mexicans In The United States, Michelle Monique Balan

LSU Master's Theses

This thesis analyzes the relationship between immigration and mental health. I used data from a health and migration study of Mexican immigrant women in a Houston community. I found a statistically significant negative relationship between family social support and feelings of depression. Thus, family social support may have buffered some harmful effects of immigrating to the United States. However, I found inconsistent results with labor market variables that may be due to a measurement problem. Both employment variables were statistically significant (p<.05) for models (predictor, predictor and control) including loss of interest and these variables remained significant after control variables were added. Unfortunately, only one of the work variables--the number of months the respondent worked--was in the predicted direction. Contrary to expectations, the other employment variable (ever worked) was negatively related to a loss of interest in previously pleasurable activities.

LSU Master's Theses

In recent years, biofiltration technology has gained acceptance worldwide as an economical and reliable air pollution control technology for treating gases contaminated by low concentrations of biodegradable volatile organic compounds (VOCs). Important applications include control of odors generated by wastewater treatment plants and control of VOC emissions from industrial sources. Although there have been many successful applications, several operational problems have been reported in the literature. These include difficulty in control over bed moisture content, high head loss caused by excessive biomass production, and inability to maintain removal efficiency during transient periods of high concentration loading. Use of a superior …


Signs Sense: Exploring Signs In Urban Place Making, Amy Elizabeth Pecquet Jan 2001

Signs Sense: Exploring Signs In Urban Place Making, Amy Elizabeth Pecquet

LSU Master's Theses

Signs are prominent elements of the urban landscape; they display messages to the public, orient people in complex environments, act as social landmarks, and serve as a means of cultural expression. Despite the omnipresence of signs, designers have yet to capitalize on their potential urban spaces as creative design tools for enhancing a sense of place. Using literature and urban case studies, this thesis explores several quantitative methods to learn about effects produced by signs in the urban landscape. Case studies in New Orleans, Louisiana locate every sign in defined areas on Bourbon, Royal, and Canal Street to compare and …


Synthesis And Analysis Of Three-Dimensional Molecular Architectures, Patricia Beck Jan 2001

Synthesis And Analysis Of Three-Dimensional Molecular Architectures, Patricia Beck

LSU Master's Theses

The use of resorcinarenes in the study of biologically significant phenomena has been the focus of much attention, due to the versatility of these macrocyclic compounds. In this thesis, two applications of resorcinarenes are explored. First, the search for the mechanism by which tetraarylboronic acid resorcinarenes lead to colorimetric detection and quantization of saccharide analyte concentration in solution is described. Second, the extension of the lower rim conjugation of the resorcinarene macrocycle by the fourfold addition of various length oligo(p-phenylene) rods is discussed. The synthesis of these tubular materials, with potential uses as artificial ion channels and for binding and …

Microhabitat Use In An Assemblage Of Native And Introduced Stream Fishes In Wailoa Stream, Island Of Hawaii, Mark G. Mcrae

LSU Master's Theses

To date, most research on the ecology of Hawaiian stream fishes has taken place in the middle and upper reaches of streams. In the terminal reaches of streams in Hawaii, the ecological aspects of the relatively more diverse fish assemblages are largely unknown. This study investigated patterns of microhabitat use in an assemblage of native and introduced stream fishes living in the terminal reach of Wailoa Stream on the Island of Hawaii. Multivariate and univariate analyses of microhabitat data collected through underwater visual surveys indicated that differences in microhabitat preferences were an important factor in the structure of this assemblage. …

In recent years, the published objectives of international aid organizations have called for the expertise of landscape architects. Projects with attention to sustainability, environment, and land use have become a major emphasis for many organizations. Landscape architecture, a profession which involves physical science, social science, humanities, art and land, is an appropriate profession to participate in aid projects. As a result of their unique training and experience, landscape architects have an unusual opportunity to make a substantial contribution in the planning, design and development of places for people in developing countries. This case study documents the activities and explains a …


Effects Of Water Color On Food Web Structure In Freshwater Lakes, Bjoern Wissel Jan 2001

Effects Of Water Color On Food Web Structure In Freshwater Lakes, Bjoern Wissel

LSU Doctoral Dissertations

Water color has multiple effects on freshwater lakes, changing the vertical profiles of light, temperature, and oxygen. Therefore, increased water color should reduce planktivory by visually guided fish, but invertebrate predators such as Chaoborus should become more important. Since fish prefer larger prey but Chaoborus can only ingest smaller zooplankton, increased water color should cause a shift from small to large zooplankton species. To test this hypothesis, I analyzed two lake data sets to examine how water color affects the relative importance of fish and Chaoborus as planktivores. Subsequently, I studied the vertical migration behavior of the zooplankton prey in …


Influence Of Short-Term Endurance Exercise Training On Heart Rate Variability, Clarence Matthew Lee Jan 2001

Influence Of Short-Term Endurance Exercise Training On Heart Rate Variability, Clarence Matthew Lee

LSU Doctoral Dissertations

The purpose of this investigation was to determine if 8 exercise endurance training (ET) sessions over 2 weeks significantly alters cardiac autonomic modulation, as measured by heart rate variability (HRV). Twenty-four college-aged males were recruited for this study and were randomized into either an exercise group (EX; n=12) or a control group (CT; n=12). EX underwent 2 weeks of ET on a cycle-ergometer (frequency: four times/week; duration: 40 minutes; intensity 80-85% HRreserve), whereas CT was instructed not to alter their previous level of physical activity. Five-minute ECG tracings were collected for HRV under the following conditions: 5 minutes of paced …


A Reexamination Of The Canon Of Objectivity In American Journalism, Les L. Lane Jan 2001

A Reexamination Of The Canon Of Objectivity In American Journalism, Les L. Lane

LSU Master's Theses

Journalistic objectivity is the definitive canon of American mainstream journalism. Yet American journalists cannot agree on what it is, how it is measured, or on how it is done. The source of the confusion is the assumption that objectivity is an ideal, absolute, impossible, incomprehensible, value-free state of being, outside of all physical, cognitive, psychological, and social contexts, where reality is perceived without distortions of any kind. This assumption is logically invalid and historically inaccurate. Journalistic objectivity evolved from the American cultural premises of egalitarianism and positive scientific empiricism through four historical stages: Nonpartisanship, Neutrality, Focus-On-Facts, and Detachment. It is …


Electrodeposition Of Niw Alloys Into Deep Recesses, Lakshmikanth Namburi Jan 2001

Electrodeposition Of Niw Alloys Into Deep Recesses, Lakshmikanth Namburi

LSU Master's Theses

Pulse electrodeposition has been investigated as a general technique for the electrodeposition of nickel-tungsten alloys in deep recesses for MEMS. Ni-W exhibits an induced codeposition mechanism, where the Ni reaction rate enhances the codeposition of W. Electrodeposition of this alloy has been achieved into recesses of 500 micron deep. The challenges that have been encountered are those related to gas evolving side reactions, local pH rises, diffusional limitations of the soluble species and long times required for filling the recesses. Electrodeposition on cylinder electrodes at different rotation rates was also carried out in order to obtain data on composition of …

Mass Media Ethics Vs. Ethnicity : The Cuban American National Foundation's Battle With The Miami Herald, Michelle M. Cobas

LSU Master's Theses

In 1992, a prominent Cuban-American organization, the Cuban American National Foundation, launched a full-scale campaign against the Miami Herald following an editorial against the Cuban Democracy Act, sponsored by Congressman Robert Torricelli, (D-NJ). The bill, which the Foundation endorsed and helped craft, was aimed at tightening the loopholes on the U.S. embargo against Cuba. Two men-CANF Chairman Jorge Mas Canosa and Herald publisher David Lawrence-represented opposing sides of the feud. CANF galvanized the exile community to support its side of the debate. The Herald used its opinion and editorial pages to argue against Mas's charges that the newspaper attacked the …

Translating Exile In Panait Istrati's "Mes Departs", Samuel Beckett's "Fin De Partie" And Selected Poems By Paul Celan., Ina Alice Pfitzner Jan 2001

Translating Exile In Panait Istrati's "Mes Departs", Samuel Beckett's "Fin De Partie" And Selected Poems By Paul Celan., Ina Alice Pfitzner

LSU Historical Dissertations and Theses

Translation and exile are two phenomena that marked life in the twentieth century, especially in Europe, and have therefore left their traces in French literature as well. Translation from one language to another is a heightened form of the translation process inherent in any writing. Exile in a foreign country, linguistic exile, is an aggravated form of the exile every human being experiences at some point. Parting from Lucian Blaga's concept of "mioritic space," which is based on the Romanian myth of Mioritza, as well as Walter Benjamin's essay "Die Aufgabe des Ubersetzers" [The Task of the Translator], this study …
