Ammoniation Of Cellulosic Materials For Use In Fertilization And Oil Spill Remediation., Ananda Padmasiri De Silva Jan 1995

Ammoniation Of Cellulosic Materials For Use In Fertilization And Oil Spill Remediation., Ananda Padmasiri De Silva

LSU Historical Dissertations and Theses

The stringent environmental regulations, rising cost, public concerns, and the limited availability of landfills for disposal of organic wastes have stimulated efforts to identify cost-effective, environmentally sound, alternative waste disposal technologies. The value of organic wastes as soil amendments is limited by their low nutrient value, occasional strong odors and high costs of transportation. The primary goal of this investigation was to develop a process to enrich the N content and to reduce the water content of organic wastes in order to enhance the value of these wastes for use in fertilization and oil spill remediation. A chemical process was …

Submergence Impacts On Selected Wetland/Bottomland Tree Species., Jian Sun Jan 1995

Submergence Impacts On Selected Wetland/Bottomland Tree Species., Jian Sun

LSU Historical Dissertations and Theses

Flooding is a common natural stress occurring in wetland/bottomland forests. Submergence, total immersion, is a special case of flooding, which has received limited attention in the literature. This study provides information on the impacts of three submergence treatments on three bottomland tree species. The results indicated that submergence would inhibit shoot and root growth for the three tested species during the submergence period. However, the survival of these species under submergence conditions were different. Taxodium distichum (L.) Rich survived even after 30 days of water coverage and survival continued to be high during the recovery period. Quercus nuttallii Palmer was …

Mechanisms Of Resistance To Aflatoxin Accumulation By Aspergillus Flavus In Maize Genotype Gt-Mas:Gk., Baozhu Guo Jan 1995

Mechanisms Of Resistance To Aflatoxin Accumulation By Aspergillus Flavus In Maize Genotype Gt-Mas:Gk., Baozhu Guo

LSU Historical Dissertations and Theses

Maize genotype differences in aflatoxin production were observed when kernels of resistant GT-MAS:gk and thirteen susceptible commercial hybrids were inoculated with Aspergillus flavus using a laboratory kernel screening assay. GT-MAS:gk supported the lowest levels of aflatoxin in both intact and endosperm-wounded kernels. Treating intact kernels with KOH effected substantial increases in aflatoxin accumulation in GT-MAS:gk, but only marginal increases in Pioneer 3154. Removing wax from the surface of GT-MAS:gk kernels greatly increased aflatoxin accumulation. These results indicated that GT-MAS:gk resistance was associated with an intact pericarp (wax and cutin layers), acting as a physical barrier, along with internal biochemical factors. …

Remediation Of Contaminated Soils Using A Plant Based Surfactant., Raghava Rao Kommalapati Jan 1995

Remediation Of Contaminated Soils Using A Plant Based Surfactant., Raghava Rao Kommalapati

LSU Historical Dissertations and Theses

A plant based surfactant extracted from fruit pericarps of Sapindus mukurossi (Ritha) is employed for the first time to investigate remediation of contaminated soils. A method for preparing natural surfactant solutions was developed and the solutions were characterized followed by generation and characterization of colloidal gas aphron (CGA) suspensions produced with these solutions. The variation of hexachlorobenzene (HCB) solubility with natural surfactant solutions was estimated and desorption of HCB from soils was investigated with batch and on-dimensional column experiments. Bioenhancement of soil microorganisms in natural surfactant solutions was studied under both aerobic and anaerobic conditions. The empirical formula for natural …

Mathematical Problems In Elasticity And Quantum Mechanics., Genbao Shi Jan 1995

Mathematical Problems In Elasticity And Quantum Mechanics., Genbao Shi

LSU Historical Dissertations and Theses

This thesis is concerned with new mathematical contributions to this area of mathematical physics. It consists of two parts. The first part discusses Pauli uniqueness problem in the content of locally compact abelian groups. We get improved results for $R\sp{n}$, new results for $T\sp{n}$ and $Z\sb{n}$. In the second part which is the main part of the thesis, we develop a new approach to the scattering for Nth order factored equations based on an abstract version of d'Alembert's formula. We show that the asymptotic equivalence (or scattering theory) of the pair of higher order factored equations reduces to the asymptotic …

Use Of A Natural Swamp For Wastewater Treatment., Xiaowei Zhang Jan 1995

Use Of A Natural Swamp For Wastewater Treatment., Xiaowei Zhang

LSU Historical Dissertations and Theses

The purposes of this research were to determine the possibility of using a natural forested swamp for advanced wastewater treatment in coastal Louisiana, and to evaluate the wastewater impact on the ecosystem. The study was performed by comparing two portions of a nutrient deficient swamp separated by a ridge. One portion received secondarily treated municipal wastewater at a rate of $6.3\times10\sp6$ L/day and the other served as a control. Concentrations of BOD$\sb5$, TSS, DO, EC, TDS, pH, N, P, S, CI, K, Ca, Mg, Na and trace metals were monitored. Results showed that the wastewater added nutrients into the swamp. …

Interactions Of Weeds, Herbicides, And Aerial Blight (Rhizoctonia Solani) In Soybeans., Bryan David Black Jan 1995

Interactions Of Weeds, Herbicides, And Aerial Blight (Rhizoctonia Solani) In Soybeans., Bryan David Black

LSU Historical Dissertations and Theses

Field studies evaluated soybean response to Rhizoctonia foliar blight (RFB) (Rhizoctonia solani AG-1 IA and IB) and interference from common cocklebur, hemp sesbania, or johnsongrass. Soybean maturity was delayed both years by hemp sesbania whether or not RFB was present. Soybean yield was reduced 20% in plots inoculated with the RFB pathogen in 1993, but not in 1994. Soybean yield was reduced only when inoculated plots were infested with common cocklebur and johnsongrass in 1993 and with hemp sesbania and johnsongrass in 1994. Acifluorfen, glufosinate, glyphosate, paraquat, and pendimethalin were evaluated for effects on mycelial growth and sclerotia/microsclerotia production by …

Race And The Fragmented Self In Twentieth-Century American Literature., Jerold Malcolm Martin Jan 1995

Race And The Fragmented Self In Twentieth-Century American Literature., Jerold Malcolm Martin

LSU Historical Dissertations and Theses

Beginning with a definition of "race" as a system of discourse about human difference sustained by its symbolic articulations, I approach "race" as analogous to the social disciplines that Foucault describes as constructing the modern subject. Bringing together certain speculations of Lacan, Fanon, and Morrison, I suggest that this racial discipline facilitates a racial "mirror stage" through which "blackness" and "whiteness" are projected as distinct and unified conceptions of identity. My readings of representative texts examine how such racial identity patterns are both seductive as resolutions of self-discord and destructive in tension with the multiple, interpersonal, and historical determinations of …

The Church In Post-Transition Societies: Evidence From Eastern Europe., Mary L. Gautier Jan 1995

The Church In Post-Transition Societies: Evidence From Eastern Europe., Mary L. Gautier

LSU Historical Dissertations and Theses

I explore the relationship between religious affiliation and support for democratic values in postcommunist societies. Using the Tocquevillian idea of the institutional learning of democratic values within civil society, I examine three post-transition countries of Eastern Europe for evidence that the churches preserved and promoted democratic values during the years of Soviet regime control. Comparative historical examination of the relationship between the institutional churches and the state during the years of communist regime control demonstrate how the churches worked to preserve and promote democratic values. In those countries where the churches were marginalized and excluded from power by the state …

Solid Removal Schemes And The Rotating Biological Contactor In Recirculating Fish Culture Systems., Aurelio Alfonso Delos Reyes Jr Jan 1995

Solid Removal Schemes And The Rotating Biological Contactor In Recirculating Fish Culture Systems., Aurelio Alfonso Delos Reyes Jr

LSU Historical Dissertations and Theses

The performance of combinations of the Norpac$\sp\circler$ tube RBC with a bead filter (System I), a tube settler (System II), and a sand filter (System III) in pilot scale recirculating systems stocked with tilapia were evaluated and compared. Good fit empirical equations were obtained relating TAN and NO$\sp2$-N (both exponential), and DO (linear) with daily amount of feed. Likewise, linear equations relating bead filter or sand filter pressure with feed, and flow with pressure were obtained. Systems I and II maintained favorable water quality up to the maximum feed load studied of 3 kg/day. System III effectively handled only 1.2 …

Rhetoricizing Habermas: The Restoration Of Legitimacy As A Theme In The 1992 Televised Presidential Debates., Kevin Travis Jones Jan 1995

Rhetoricizing Habermas: The Restoration Of Legitimacy As A Theme In The 1992 Televised Presidential Debates., Kevin Travis Jones

LSU Historical Dissertations and Theses

During the past twenty years, scholars have posited the emergence of a legitimacy crisis in the American political system. Symptoms of the crisis were low voter turn out and a culture of withdrawal, cynicism, alienation, and a widespread perception of institutional incompetence and indifference. At the very least, the widespread mood of apathy and decline have been seized upon by various candidates seeking political office, in particular the presidency, who routinely engage in discourse targeting legitimacy restoration. This discourse echoed the general theme of the Jeffersonian Myth. This myth, which predates Jefferson in its old Roman roots, targets the citizen …

Solution Behavior Of Cascade Polymers., Keunok Han Yu Jan 1995

Solution Behavior Of Cascade Polymers., Keunok Han Yu

LSU Historical Dissertations and Theses

This thesis consists of four chapters. In the first, a general introduction is presented. Chapter 2 deals with the characterization of polyamidoamine (PAMAM) cascade polymers. Diffusion coefficients of four different generations (generation 3, 5, 7, and 9) of PAMAMs were measured in aqueous solutions by dynamic light scattering. Generation 3 and 5 were characterized again, after labeling with fluorescein isothiocyanate, by fluorescence photobleaching recovery. The dynamic light scattering results depended on the concentration of added salt in the low salt limit, while the fluorescence values were almost independent of salt concentration. The polyelectrolyte effects, or solution nonidealities, strongly affected light …

Diallel Analyses Of Percent Kernel Infection By Aspergillus Flavus And Ear Moisture Loss Rate In Maize., Yudong Zhang Jan 1995

Diallel Analyses Of Percent Kernel Infection By Aspergillus Flavus And Ear Moisture Loss Rate In Maize., Yudong Zhang

LSU Historical Dissertations and Theses

Preharvest infection by Aspergillus flavus Link ex Fries and subsequent aflatoxin contamination of maize (Zea mays L.) grain are major production problems. Ear moisture loss rate (EMLR) is an important component of hybrid performance and maturity, and to some extent determines the suitability of a hybrid for a geographical area. A 10-parent diallel experiment was conducted in 1992 and 1994 to study the genetic nature of both percent kernel infection (PKI) by A. flavus and EMLR. General combining ability (GCA, V$\sb{\rm g}$), specific combining ability (SCA, V$\rm\sb{s}$), and reciprocal mean squares for PKI were significant. The ratio $\rm 2V\sb{g}/(2V\sb{g}+V\sb{s}$) was …

The Dual Voices Of The Civil Rights Movement: The Heroic Narratives Of Martin Luther King, Jr. And Malcolm X., Kerry Paul Owens Jan 1995

The Dual Voices Of The Civil Rights Movement: The Heroic Narratives Of Martin Luther King, Jr. And Malcolm X., Kerry Paul Owens

LSU Historical Dissertations and Theses

Since reconstruction African-American leaders have embodied conflicting aspirations. While some leaders like Booker T. Washington and Frederick Douglass urged complete assimilation, others like W. E. B. DuBois and Marcus Garvey have preached autonomy and separation. These leaders have tended to serve as icons for rival programs; their rhetoric as authoritative, and their lives as inspired models for future leaders. This dissertation examines the hagiography of the two most famous leaders of the late 20th century, Martin Luther King, Jr. and Malcolm X. It argues that their rhetoric was undergirded by the myth of the heroic quest and that their lives …

Modeling The Antecedents Of Compulsive Buying., Leslie K. Cole Jan 1995

Modeling The Antecedents Of Compulsive Buying., Leslie K. Cole

LSU Historical Dissertations and Theses

Interest in dysfunctional consumption behaviors, such as compulsive buying, is a fairly recent development in the marketing literature. The purpose of this dissertation was to develop and test a theoretical model of the structural relationships among potential antecedents of compulsive buying behavior. In this dissertation, an extensive literature review identified several key constructs in the development of compulsive buying. These constructs include a family environment factor (parental influence), obsessive-compulsive trait, trait self-esteem, generalized anxiety, impulsive behavior, and anxiety reduction through shopping motivations. Seven studies were performed, including pretest and final studies with national non-student samples. Using LISREL, a structural model …

Wiretapping And National Security: Nixon, The Mitchell Doctrine, And The White Panthers. Volume I., Jeff A. Hale Jan 1995

Wiretapping And National Security: Nixon, The Mitchell Doctrine, And The White Panthers. Volume I., Jeff A. Hale

LSU Historical Dissertations and Theses

This dissertation discusses a modern version of a constitutional struggle which has characterized American democracy since the first days of the Republic: the citizen's right to privacy versus the Government's need to guarantee "national security." It addresses the Supreme Court's landmark Fourth Amendment wiretapping decision of June 1972, U.S. v. U.S. District Court, which ruled unconstitutional the so-called "Mitchell Doctrine", the Nixon Administration's attempt to gain Judicial sanction for "national security" wiretaps without prior court order of suspected "domestic subversive" groups. In its unanimous Keith decision, the Court upheld the "primacy of warrants" in domestic intelligence investigations. Keith remains the …

Synthesis Of Benz(F)Tryptophan And Constrained Amino Acid Derivatives As Fluorescence Probes., Guillermo Morales Jan 1995

Synthesis Of Benz(F)Tryptophan And Constrained Amino Acid Derivatives As Fluorescence Probes., Guillermo Morales

LSU Historical Dissertations and Theses

Constrained amino acids and benzannulated analogs of indole were synthesized as potential fluorescence probes of peptide structure. 1-Amino-2-(3-indolyl)-cyclohexane-1-carboxylic acid (W3) is a rotationally-restricted tryptophan analog whose C$\sb\alpha$-C$\sb\beta$ bond is part of a 6-membered ring. Friedel-Crafts reaction between $\alpha$-hydroxycyclohexanone and indole affords 2-(3-indolyl)cyclohexanone which is further converted into its corresponding spirohydantoin derivative via Strecker reaction. Basic hydrolysis of this hydantoin derivative with Ba(OH)$\sb2$ in oxygen-free water at 250$\sp\circ$C in a Parr$\sp\circler$ high pressure bomb afforded the constrained tryptophan analog. N-(t-Boc)piperidine-4-amino-4-carboxylic acid is a constrained Aib analog. Treatment of 4-piperidinone monohydrate hydrochloide with triethyl amine, catalytic amounts of N,N-dimethylamino pyridine and di-tert-butyl …

A Comparison Of Preference Responses Of White And African-American Students To Musical Versus Musical/Visual Stimuli And Their Relationship To Same- And Other Group Attitudes., Steven Joseph Morrison

LSU Historical Dissertations and Theses

It was the purpose of this study to examine the role of same- and other-group identification in musical preference decision-making and the relationship between preference decisions and attitude-oriented responses to hypothetical social encounters with same- and other-group members. Subjects were African-American (n = 189) and white (n = 280) sixth, seventh and eighth grade music students. To measure musical preference, each subject responded along a 9-point Likert scale to 10 instrumental music excerpts, five performed by African-American jazz artists and five performed by white jazz artists. The examples were presented according to one of three conditions: (1) music only, (2) …

Host-Guest Chemistry Of Cofacial Binuclear Copper(Ii) And Zinc(Ii) Complexes Of Bis(Beta-Diketone) Ligands., Laurie A. Brown Jan 1995

Host-Guest Chemistry Of Cofacial Binuclear Copper(Ii) And Zinc(Ii) Complexes Of Bis(Beta-Diketone) Ligands., Laurie A. Brown

LSU Historical Dissertations and Theses

We have been synthesizing cofacial binuclear copper(II) and zinc(II) complexes using bis($\beta$-diketone) ligands in order to design a host complex which selectively binds guest molecules and demonstrates catalytic activity. The metal atoms are held by the chelating acetylacetonate groups, of the bis($\beta$-diketone) ligands, in adjacent parallel planes separated by a cavity into which the guest molecule fits. The host-guest interactions are described. The synthesis of these complexes are discussed beginning with the synthesis of the substituted naphthalenes which bridge the meta-acetylacetonate planes. We needed 2,7-dimethylnaphthalene-1-carbonitrile for the synthesis of the bis($\beta$-diketone) ligand, NBAH$\sb2$-1-CN. After the first recrystallization of 2,7-dimethylnaphthalene-1-carbonitrile, it …

Cloning And Functional Characterization Of Lcr-F1: A Bzip Transcription Factor That Activates Erythroid-Specific, Human Globin Gene Expression, John J. Caterina, David Donze, Chiao Wang Sun, Dominic J. Ciavatta, Tim M. Townes

Faculty Publications

DNase I hypersensitive site 2 (HS 2) of the human β-globin Locus Control Region (LCR) directs high level expression of the β-globin gene located 50 kilobases downstream. Experiments in cultured cells and in transgenic mice demonstrate that duplicated AP1-like sites in HS 2 are required for this powerful enhancer activity. A cDNA clone encoding a basic, leucine-zipper protein that binds to these sites was isolated and designated Locus Control Region-Factor 1 (LCR-F1). This protein is a member of a new family of regulatory factors that contain a 63 amino acid 'CNC domain' overlapping the basic region. This domain is approximately …

Development Of Aluminum Tolerance In Rice (Oryza Sativa L.) Through Tissue Culture Techniques., Herry S. Utomo Jan 1994

Development Of Aluminum Tolerance In Rice (Oryza Sativa L.) Through Tissue Culture Techniques., Herry S. Utomo

LSU Historical Dissertations and Theses

Three tissue culture techniques, somaclone evaluation, in vitro screening of suspension cells, and in vitro screening of protoplasts were evaluated for their potential to produce aluminum (Al) tolerant rice. For somaclone evaluation, a collection of 9,000 rice somaclones was screened. After 11 days of germination in 200 uM Al, the length of the primary root was measured and used as the criterion for selection since a principal effect of Al toxicity is inhibition of root growth. Four superior lines were identified. Root length of the most tolerant line was 50% greater than its control following germination in screening solution. A …

Development Of A Body Image Assessment Procedure For Children And Pre-Adolescents., Staci Veron Guidry

LSU Historical Dissertations and Theses

Eating disorders have been researched extensively among adult, and, more recently, among adolescent populations. Body image disturbance is included as a diagnostic criterion for anorexia nervosa and bulimia nervosa, and has been postulated as a central characteristic of the eating disorders. Researchers have identified eating disorders among prepubertal children; therefore, there is a need for the development of reliable and valid measures of eating disorders and body image in children. In this investigation, a total of 257 children in grades 3 through 7 completed the Children's Eating Attitudes Test, Children's Depression Inventory, Piers-Harris Children's Self Concept Scale physical appearance and …

The coronavirus strain HECV‐4408 was isolated from diarrhea fluid of a 6‐year‐old child with acute diarrhea and propagated in human rectal tumor (HRT‐18) cells. Electron microscopy revealed coronavirus particles in the diarrhea fluid sample and the infected HRT‐18 cell cultures. This virus possessed hemagglutinating and acetylesterase activities and caused cytopathic effects in HRT‐18 cells but not in MDBK, GBK and FE cells. One of four S‐specific monoclonal antibodies reacted in Western blots with HECV‐4408, BCV‐L9 and BCV‐LY138 but not with HCV‐OC43, and two reacted with BCV‐L9 but not with HECV‐4408, BCV‐LY138 and HCV‐OC43.

Interactions Of Mouse And Bovine Preimplantation Embryos Prior To And After The In Vitro Developmental Block Stage., Leyi Li

LSU Historical Dissertations and Theses

The objective of the present study was to evaluate the effect of post-block mouse and bovine embryos on the development of pre-block embryos around the in vitro developmental block stage. The effect of the post-block embryos on the development of the pre-block embryos was evaluated in culture, in chimeras and in cytoplasmic hybrid embryos. The results indicate that post-block embryos were able to stimulate the development of the pre-block embryos in culture. The stimulatory effect of the post-block mouse and bovine embryos was found not to be species-specific and was synergistic with that of bovine granulosa cells. Chimeric parthenogenetic bovine …
