Bioenergetics Of Red Swamp Crawfish (Procambarus Clarkii) And White River Crawfish (Procambarus Acutus Acutus) In Cultivated, Noncultivated And Wooded Ponds In South Louisiana., Mattana Sanguanruang Jan 1988

Bioenergetics Of Red Swamp Crawfish (Procambarus Clarkii) And White River Crawfish (Procambarus Acutus Acutus) In Cultivated, Noncultivated And Wooded Ponds In South Louisiana., Mattana Sanguanruang

LSU Historical Dissertations and Theses

Stomach content analysis and stable carbon isotope ratios were used to determine diet and food assimilation of red swamp crawfish (Procambarus clarkii) and white river crawfish (Procambarus acutus acutus) in three types of commercial ponds. Crawfish stomachs contained largely macrophytes, detritus and leaf litter, and to a lesser extent aquatic insects and zooplankton. Food habits of P. clarkii and P. acutus acutus were similar, but P. acutus acutus consumed more animal material than did P. clarkii. Food habits were similar among different sizes of P. clarkii and P. acutus acutus. Seasonal stable carbon isotope ratios ($\delta\sp{13}$C) of P. clarkii and …

Site-Directed Mutagenesis In Fructose 6-Phosphate-1-Kinase From Bacillus Stearothermophilus And Molecular Cloning And Sequencing Of A Partial Human Muscle Fructose 6-Phosphate-1-Kinase Gene., Benigno Calderon Valdez Jan 1988

Site-Directed Mutagenesis In Fructose 6-Phosphate-1-Kinase From Bacillus Stearothermophilus And Molecular Cloning And Sequencing Of A Partial Human Muscle Fructose 6-Phosphate-1-Kinase Gene., Benigno Calderon Valdez

LSU Historical Dissertations and Theses

Fructose 6-phosphate-1-kinase (PFK: EC. 2.7.1.11) catalyzes the phosphorylation of $\beta$-fructose 6-phosphate (Fru 6-P) to $\beta$-fructose 1,6-bisphosphate. The first part of this dissertation shows that PFK from Bacillus stearothermophilus (BsPFK) unlike the major PFK from E. coli (EcPFKA) exhibits a hyperbolic profile with respect to Fru 6-P concentration in the absence of phosphoenolpyruvate (PEP). BsPFK is sensitive to inhibition by high ATP concentrations and competitively inhibited by GDP or ADP. Arg-252 residue of BsPFK has been proposed to be involved in the binding of Fru 6-P. Mutation of this residue to alanine (RA252) increases BsPFK affinity for its inhibitor PEP (a …

A History And Daybook Of The English Language Theatre In New Orleans During The Civil War. (Volumes I And Ii)., Paula June Thompson Jan 1988

A History And Daybook Of The English Language Theatre In New Orleans During The Civil War. (Volumes I And Ii)., Paula June Thompson

LSU Historical Dissertations and Theses

This study investigates the theatrical activity in New Orleans between 1860 and 1865 and provides a daybook including all recorded performances in the city during this period. Many active theatres existed in New Orleans prior to 1860. Three theatres, the St. Charles, the Varieties, and the Academy of Music dominated professional English-language dramatic offerings. They brought in the most renowned performers of the period and presented lavish dramatic productions, minstrel shows, circuses and concerts. This study explores the impact of the war on the theatrical activity of these three theatres and attempts to chronicle the adjustments necessary to continue operation. …

"Can You Tell Me Who My People Are?" Ethnic Identity Among The Hispanic-Indian People Of Sabine Parish, Louisiana, Mary B. Van Rheenen Aug 1987

"Can You Tell Me Who My People Are?" Ethnic Identity Among The Hispanic-Indian People Of Sabine Parish, Louisiana, Mary B. Van Rheenen

LSU Historical Dissertations and Theses

This thesis explores the puzzle of ethnic identity for the Hispanic-Indian people of Sabine Parish. Because their unique history precludes the clear-cut ethnic identification available to immigrant American groups, the community shares the awkward social position of both the remnant Native American groups and mixed-blood communities collectively known as American Isolates. The issue of group identity for members of the Zwolle-Ebarb community has been further confounded by the internal and external stigmas attached to aspects of the group's origins as well as the negative image associated with the group's home territory. After the people have been identified historically and genealogically, …

A Critical Examination Of The Mythological And Symbolic Elements Of Two Modern Science Fiction Series: "Star Trek" And "Doctor Who"., Gwendolyn Marie Olivier Jan 1987

A Critical Examination Of The Mythological And Symbolic Elements Of Two Modern Science Fiction Series: "Star Trek" And "Doctor Who"., Gwendolyn Marie Olivier

LSU Historical Dissertations and Theses

Carl Gustav Jung and Joseph Campbell both believe that a living mythology is a necessary factor in a viable civilization. According to these two scholars it is the self-actualized individual who is the key element in a healthy society. The purpose of a mythology for Jung and Campbell is to provide the individual with a set of symbols that will assist him in the process of self-realization. Jung believed that the major source of mythology in today's world is dreams, but he acknowledged the fact that anything which provided the unconscious mind with the appropriate symbols could function on a …

Cerebroprotective Activity Of U-50488h: Relationship To Interactions With Excitatory Amino Acids And Calcium., Marlene Camacho Ochoa Jan 1987

Cerebroprotective Activity Of U-50488h: Relationship To Interactions With Excitatory Amino Acids And Calcium., Marlene Camacho Ochoa

LSU Historical Dissertations and Theses

The mechanism underlying the anticonvulsant and cerebroprotective activity of U-50488H was evaluated using $\sp{45}$Ca$\sp{++}$ uptake in rat Ficoll purified synaptosomes, ($\sp3$H)-2-deoxyglucose uptake in selected mouse brain regions, ($\sp3$H)kainic acid binding to mouse forebrain synaptic membranes and incidence of KA-induced lesions in the CA3 region of the mouse hippocampus. U-50488H causes reduction in K$\sp+$-evoked $\sp{45}$Ca$\sp{++}$ uptake. These effects are comparable to those of the calcium channel blockers verapamil and nifedipine and seem to be related to calcium dependent mechanisms. Changes in saturability, specificity and dissociation constant values of kainic acid receptor binding were demonstrated in the presence of U-50488H at concentrations …

Dimethylnitrosamine - Induced Neoplasms In F344 Male Rats With Various Manipulations Of The Mixed-Function-Oxidase System: Macroscopic, Microscopic, Ultrastructural, And Immunocytochemical Evaluation., John Michael Gliatto Jan 1987

Dimethylnitrosamine - Induced Neoplasms In F344 Male Rats With Various Manipulations Of The Mixed-Function-Oxidase System: Macroscopic, Microscopic, Ultrastructural, And Immunocytochemical Evaluation., John Michael Gliatto

LSU Historical Dissertations and Theses

Aminopyrine and nitrite were administered to male F344 rats at concentrations of 1 mg each per ml drinking water as precursors of dimethylnitrosamine (DMN). Rats were divided into groups based on manipulations of the mixed-function-oxidase (MFO) system including: partial hepatectomy, subcutaneous injections of aminoacetonitrile (AAN), phenobarbital (plus 1.75% ethanol) and 1.75% ethanol. Rats were killed at 4 weeks, 12 weeks, 24 weeks, and 36 weeks following initiation of the carcinogenic regimen. DMN-induced neoplasms occurred in the liver, kidneys, and lungs. The number and types of tumors, as well as the target organ affected depended on the particular MFO system manipulation. …

Production And Evaluation Of Antisera And Monoclonal Antibodies Directed Against The Serovar-Specific Lipopolysaccharide Antigens Of Vibrio Cholerae., Linda Benton Adams Jan 1987

Production And Evaluation Of Antisera And Monoclonal Antibodies Directed Against The Serovar-Specific Lipopolysaccharide Antigens Of Vibrio Cholerae., Linda Benton Adams

LSU Historical Dissertations and Theses

Vibrio cholerae is typed serologically on the basis of somatic O-antigens. The serovar-specific antigens A, B, and C of V. cholerae O1 are located in the polysaccharide (PS) moiety of the lipopolysaccharide (LPS) in the cell wall, but the exact structure and composition of these antigens are unknown. Presently, V. cholerae non-O1 serovars are differentiated serologically by two independent typing systems. Each system utilizes whole cell vaccines which result in typing sera containing serovar-specific, anti-PS activity and non-specific, cross-reacting activities. Serovar-specific anti-PS sera were produced in rabbits immunized with PS extracted from selected vaccine strains of V. cholerae O1 and …

Effects Of Interaction Between Red Rice And Two Rice Cultivars On Morphological, Physiological And Ecological Characteristics., Jairo Clavijo Jan 1987

Effects Of Interaction Between Red Rice And Two Rice Cultivars On Morphological, Physiological And Ecological Characteristics., Jairo Clavijo

LSU Historical Dissertations and Theses

Germination, emergence, and early seedling development patterns were analyzed for red rice (Oryza sativa L.) and the rice (Oryza sativa L.) cultivars Mars, Saturn, Lemont and Bellemont. Red rice had the highest germination percentage, fastest emergence rate, and earliest development of both shoots and roots. These results suggest that the competitive ability of red rice is based on these characteristics which enable it to preempt more resources at early stages of stand development. Interaction between red rice and Lemont or Mars was evaluated by comparing morphological and physiological characteristics of these plants when grown in pure stands and in 50:50 …

Cognitive Strategy Training Effects On Reading Comprehension In Learning-Disabled Readers., Erin Cuccia Agostini Jan 1987

Cognitive Strategy Training Effects On Reading Comprehension In Learning-Disabled Readers., Erin Cuccia Agostini

LSU Historical Dissertations and Theses

This study was conducted to investigate the hypothesis that learning disabled children with reading deficits demonstrate a "production deficiency" by failing to spontaneously employ appropriate cognitive strategies in reading situations. Moreover, it was anticipated that providing them with explicit instruction regarding these strategies would improve their comprehension. Thirty learning disabled seventh- and eighth-grade students were randomly assigned to one of three training conditions: (a) summarization, (b) self-questioning, and (c) control. The effectiveness of the training strategies was assessed by having students write an 80-word summary and answer a 10-item multiple choice comprehension test on each of two passages during three …

Molecular Cloning And Sequencing Of The Bacillus Stearothermophilus 6-Phosphofructo-1-Kinase Gene And Of A Partial Rabbit Muscle 6-Phosphofructo-1-Kinase Complementary-Dna., Brent Arthur French Jan 1987

Molecular Cloning And Sequencing Of The Bacillus Stearothermophilus 6-Phosphofructo-1-Kinase Gene And Of A Partial Rabbit Muscle 6-Phosphofructo-1-Kinase Complementary-Dna., Brent Arthur French

LSU Historical Dissertations and Theses

A system is presented for determining the relationships between structure and function in the allosteric enzyme 6-phosphofructo-1-kinase (PFK). The ATP-dependent phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate catalyzed by PFK is the first reaction unique to the glycolytic pathway. The structure-function relationships in PFK can now be addressed by site-specific mutagenesis. This is a method for directly testing hypotheses concerning the functions of individual amino acids in a protein molecule. The main body of this dissertation is composed of three sections. The first two sections describe the development of a system by which the structure-function relationships in Bacillus stearothermophilus PFK …

In Vitro Regeneration And Protein Changes Associated With Two Cultivars Of Agrostis Palustris Huds. Cultured Under High Sodium-Chloride Conditions., John Casper Hovanesian Jan 1987

In Vitro Regeneration And Protein Changes Associated With Two Cultivars Of Agrostis Palustris Huds. Cultured Under High Sodium-Chloride Conditions., John Casper Hovanesian

LSU Historical Dissertations and Theses

Calli from 'Penneagle' and 'Seaside' creeping bentgrass (Agrostis palustris Huds.) were selected for enhanced ability to proliferate on media supplemented with 514 mM NaCl. Based on dry matter production and vigor, growth of plants regenerated from NaCl-adapted calli of both cultivars in saline hydroponic nutrient medium, was superior to that of plants regenerated from non-adapted calli. At 257 mM NaCl, plants from NaCl-sensitive calli died or were unable to produce measurable dry matter whereas plants from NcCl-adapted calli grew well. Growth of plants from NaCl-adapted calli was inhibited at 340 mM NaCl. At 514 mM NaCl, resistant plants no longer …

The Louisiana Cooperative Extension Service: A Descriptive History Of Its Origin And Development. (Volumes I And Ii)., Edwin Clark Forrest Jr Jan 1987

The Louisiana Cooperative Extension Service: A Descriptive History Of Its Origin And Development. (Volumes I And Ii)., Edwin Clark Forrest Jr

LSU Historical Dissertations and Theses

This dissertation studies the conditions which brought the Louisiana Cooperative Extension Service (LCES) into existence in 1914 and which have sustained it for over 70 years. The U.S. Department of Agriculture estimates that 40 percent of Russia's population consists of farmers and that approximately 70 percent of China's population are farmers. The significance of these figures in relation to productivity is apparent when contrasted with the United States farm population of 2 percent. The current high level of production in American agriculture, sustained by such a small percentage of the population, is not an accident, as Professor Roy V. Scott, …

The Rational Overhauser: An Interpolating Rational Cubic Curve., Jeffrey Neil Jortner Jan 1987

The Rational Overhauser: An Interpolating Rational Cubic Curve., Jeffrey Neil Jortner

LSU Historical Dissertations and Theses

A rational interpolating cubic curve which implicitly maintains first order geometric continuity in splines has been developed. The curve is formed by blending two rational quadratic curves. Since the blending method used was originally introduced by Overhauser, this curve is referred to as the Rational Overhauser (Rover) curve. The curve formulation utilizes four shape factors to provide control of the curve. A geometrical and analytical interpretation of these shape factors and their relationship to each other is discussed. Procedures for representing conic sections using the rational Overhauser curve are presented. Also included are techniques for mapping between the Rover curve …

An Investigation Of The Inference And Mapping Components Of The Componential Theory Of Analogical Reasoning., Catherine Sheard Jan 1987

An Investigation Of The Inference And Mapping Components Of The Componential Theory Of Analogical Reasoning., Catherine Sheard

LSU Historical Dissertations and Theses

Sternberg's componential theory of analogical reasoning (1977) provides a series of steps that may be followed in order to solve analogies. According to Sternberg, when given a simple analogy (in the form A:B::C: (D$\sb1$, D$\sb2$, D$\sb3$)) the reasoner: (a) encodes the terms of the analogy, (b) infers the relation between A and B, (c) maps the relation between A and C, (d) applies a relation analogous to the inferred one from C to each answer option, choosing the closer option, and (e) responds. The purpose of this research was to further investigate the inference and mapping processes of the componential …

Insulin Receptors Of Erythrocytes And Liver Membranes In Dogs., Karen Johnson Wolfsheimer Jan 1987

Insulin Receptors Of Erythrocytes And Liver Membranes In Dogs., Karen Johnson Wolfsheimer

LSU Historical Dissertations and Theses

Insulin receptor assays using canine liver membranes and erythrocytes were validated for use in evaluating insulin receptor binding parameters within a healthy population of dogs. Association, dissociation, saturability and specificity were demonstrated for insulin receptors of canine liver membranes and erythrocytes. Assay precision was evaluated by measuring interassay coefficient of variation (liver membrane = 25.0%; erythrocytes = 9.3%). Because the number of high-affinity receptor sites and high-affinity K$\sb{\rm D}$ were determined using physiological concentrations of insulin, they were considered to be more physiologically important than the total number of receptor sites, low-affinity K$\sb{\rm D}$ and Ke, which were derived using …
