Effects Of Environmental Sodium Chloride On Percent Hatch, Yolk Utilization, And Survival Of Channel Catfish Fry, C. R. Weirich, T. R. Tiersch

Faculty Publications

Only limited research has addressed the effect of salinity on hatching of channel catfish Ictalurus punctatus eggs, and no studies have evaluated the effect of salinity on fry development and survival. This study was undertaken to determine the effect of environmental sodium chloride (0, 1, 2, and 4 g/L NaCl) on percent hatch, yolk utilization, and survival of channel catfish fry. Experiments were conducted in recirculating systems using seven egg masses (1-2 d old). Each egg mass was divided into smaller portions which remained undissociated or were dissociated with sodium sulfite (NaSO3). Eggs were incubated until hatching. Wet and dry …

God Keep Me From Ever Completing Anything: Problems Of Writing And Identity In Four American Narratives., Ralph Russell Pottle Jan 1997

God Keep Me From Ever Completing Anything: Problems Of Writing And Identity In Four American Narratives., Ralph Russell Pottle

LSU Historical Dissertations and Theses

This study examines the relationship between writing and American identity in four works--William Bradford's Of Plymouth Plantation, Benjamin Franklin's Autobiography, Herman Melville's Typee: A Peep at Polynesian Life, and Nathaniel Hawthorne's The Marble Faun: Or The Romance of Monte Beni--by illuminating the difficulty that the narrator of each work has in constructing and maintaining his vision of American identity. For Bradford and Franklin, the analysis centers on their attempts to confront the historical complexities of American society--Bradford confronting the economic realities of colonialism, Franklin confronting the difficulty of organizing governance after the American Revolution. For Melville and Hawthorne, the analysis …

A Computer Automated, Hydraulically Integrated Serial Turbidostat Algal Reactor (Histar): Mathematical Modeling And Experimental Analysis., Chandra Sekhar Theegala Jan 1997

A Computer Automated, Hydraulically Integrated Serial Turbidostat Algal Reactor (Histar): Mathematical Modeling And Experimental Analysis., Chandra Sekhar Theegala

LSU Historical Dissertations and Theses

Conceptually, the Hydraulically Integrated Serial Turbidostat Algal Reactor (HISTAR) has two components: (1) sealed turbidostats for producing a high quality algal inoculum, and (2) a series of unprotected inter-connected continuous flow stirred tank reactors (CFSTRs) for mass producing algae under approximated plug flow conditions. The hydraulic retention time of each individual CFSTR ($\theta\sb{\rm n})$ is set low enough (dilution is set high) that any suspended organisms (both contaminants and desired algae) entering the CFSTR would be washed to the next CFSTR well within their doubling time. However, as the turbidostats are employed to inoculate the first CFSTR on an almost …

Ambivalent Idylls: Hardy, Glasgow, Faulkner, And The Pastoral., Stephan Randall Toms Jan 1997

Ambivalent Idylls: Hardy, Glasgow, Faulkner, And The Pastoral., Stephan Randall Toms

LSU Historical Dissertations and Theses

Thomas Hardy, Ellen Glasgow, and William Faulkner used the pastoral mode to show the contradictions, inconsistencies, and dangers in some forms of bucolic idyll. The ambivalence of their texts toward the rural world causes many critics to deny or overlook the presence of the pastoral mode in the work of these three novelists. A study of pastoral literature reveals that its characteristics have never been as fixed as many theorists would like to believe. Pastoral redefines, subverts, and reinvents itself as it interacts with different people, cultures, and languages. The theories of Mikhail Bakhtin help us to understand textual ambivalence …

Among Women: Toni Morrison's Mothers, Sisters, And Daughters., Hazel Ruth Reames Caillouet Jan 1997

Among Women: Toni Morrison's Mothers, Sisters, And Daughters., Hazel Ruth Reames Caillouet

LSU Historical Dissertations and Theses

This work explores the relationships between and among women in the fiction of Toni Morrison. Morrison's mothers, sisters, and daughters cannot function without the love and support of a community of women. Those characters who abandon or reject this community become lost to their own world. Morrison women, thus, find themselves in and through other women. The first two chapters establish Morrison's characters in relation to those of other authors in order to show her unique sense of community. Comparing Morrison's work to Virginia Woolf's A Room of One's Own and her emphasis on individuality and isolation illustrates Morrison's dependence …

Experimental Analysis Of Aggression., Bethany Ann Marcus Jan 1997

Experimental Analysis Of Aggression., Bethany Ann Marcus

LSU Historical Dissertations and Theses

In 1982, Iwata, Dorsey, Slifer, Bauman, and Richman developed a systematic assessment method to identify the operant functions of self-injurious behavior. In this study, the Iwata et al., method was used to assess the operant functions of aggression displayed by children and adolescents with developmental disabilities. Although researchers have demonstrated that aggression serves operant functions, there has been no comprehensive analysis of aggression using the Iwata et al. method. Twelve children and adolescents participated. The experimental conditions from the Iwata et al. method were replicated (i.e., attention, instructional demand, play, no interaction); also, a tangible positive reinforcement condition was included …

Seasonal Changes In Gnrh Neurons And Effects Of Dietary Monoamine Precursors On The Hypothalamic-Gonadal Axis In House Sparrows (Passer Domesticus)., Christopher Andrew Meseke Jan 1997

Seasonal Changes In Gnrh Neurons And Effects Of Dietary Monoamine Precursors On The Hypothalamic-Gonadal Axis In House Sparrows (Passer Domesticus)., Christopher Andrew Meseke

LSU Historical Dissertations and Theses

Mechanisms modulating avian seasonal reproduction involve a complex interaction between exogenous environmental information and internal physiologic systems, such as functional changes in the hypothalamic-gonadal axis and changes in the influence of monoaminergic neurotransmitters on hypothalamic neuroendocrine cells. This project was undertaken to describe seasonal changes of the testes and immunoreactive-(ir)-gonadotropin-releasing hormone (GnRH) neurons in House Sparrows in southeastern Louisiana, and to examine the role of monoaminergic neurotransmitters in modulating seasonal reproduction through the use of dietary monoamine precursors. Testicular weights rapidly increased from February to March, peaked from April to July, when the seminiferous tubules were spermatagenically active and filled …

Developing And Field Testing Design Parameters For Customizing Agricultural Extension Education Systems In Developing Countries., Michael Brian Peter Sager Jan 1997

Developing And Field Testing Design Parameters For Customizing Agricultural Extension Education Systems In Developing Countries., Michael Brian Peter Sager

LSU Historical Dissertations and Theses

Increasingly, developing countries view the partnership of research, education, and extension in traditional agricultural extension education systems as an adaptable model for improving their agrarian economies. The process of adaptation, however, has too often followed the traditional developmental project approach and been little more than the transplantation of a predefined extension education model into a developing country with little regard to existing country specific factors which impact the effectiveness of a domestic extension system. As a result, less than satisfactory technology transfer has occurred and slow rates of agricultural economic development have been posted, painting a disappointing record for agricultural …

Flight Muscle Histolysis In The Female House Cricket, Acheta Domesticus., Rush Hoyet Oliver Jan 1997

Flight Muscle Histolysis In The Female House Cricket, Acheta Domesticus., Rush Hoyet Oliver

LSU Historical Dissertations and Theses

Flight muscle histolysis was investigated in the dorsal longitudinal muscles (DLMs) of the cricket. Histolysis in the DLMs was characterized by analysis of total protein content, tissue wet weight, and relative percent muscle shortening. Initial declines of total protein indicated the JH signal initiating histolysis occurred by Day 2. Histolysis was essentially complete by Day 3. Ligation of Day 1 crickets prevented histolysis but this inhibition could be prevented by continual topical treatments with methoprene. Ligation of Day 2 crickets did not prevent histolysis. A requirement for active protein expression was demonstrated by analysis of synthesis block by cycloheximide and …

The Role Of Binge Eating Disorder In The Estimation Of Food Intake Of Obese Individuals., Drew Arthur Anderson Jan 1997

The Role Of Binge Eating Disorder In The Estimation Of Food Intake Of Obese Individuals., Drew Arthur Anderson

LSU Historical Dissertations and Theses

Individuals with binge eating disorder (BED) share some characteristics with persons with bulimia nervosa (BN) and some characteristics of obese persons who do not have problems with binge eating. Previous studies have found that while nonbinging individuals underestimate caloric intake, patients with BN overestimate caloric intake when intake is large. The present study hypothesized that because persons with BED binge eat, they would also overestimate caloric intake. A total of 56 women (9 with BED, 23 obese nonbingers, and 24 normal weight nonbingers) estimated several portion sizes of ice cream and then ate a test meal of ice cream and …

Rickettsia Felis, A Newly Discovered Rickettsia Associated With The Cat Flea (Ctenocephalides Felis Bouche)., Jimmy Wedincamp Jr Jan 1997

Rickettsia Felis, A Newly Discovered Rickettsia Associated With The Cat Flea (Ctenocephalides Felis Bouche)., Jimmy Wedincamp Jr

LSU Historical Dissertations and Theses

A study was performed to determine the life cycle of Rickettsia felis, a novel bacterium associated with cat fleas (Ctenocephalides felis Bouche). Cat flea populations maintain R. felis in successive generations by efficient transovarial transmission. Transovarial transmission was demonstrated in our study up to 12 generations. The mean infection rate for the progeny of fleas maintained on both cats and an artificial membrane system were comparable (64.3% and 58% respectively). Cats with no prior exposure to fleas were exposed to fleas infected with Rickettsia felis and monitored monthly for seroconversion via IFA. Blood samples were assayed for the presence of …

The Polysaccharide Capsule Of Vibrio Vulnificus: Virulence, Transposon Mutagenesis, And The Identification Of An Essential Gene., Amy Buscher Zuppardo Jan 1997

The Polysaccharide Capsule Of Vibrio Vulnificus: Virulence, Transposon Mutagenesis, And The Identification Of An Essential Gene., Amy Buscher Zuppardo

LSU Historical Dissertations and Theses

The extracellular capsule polysaccharide (CPS) of Vibrio vulnificus is a primary virulence factor which allows survival of the bacteria in the human host. To study the genes involved in the production of the polysaccharide capsule, 23 mutants were generated that lost their ability to produce CPS due to the insertion of a mini-transposon into the genome of the encapsulated clinical strain V. vulnificus 1003 (O). The mutants were examined by Southern blot analysis to ensure the transposon had inserted only once in the chromosome. Exoenzymes, which are believed to contribute to the virulence of the organism, produced by all 23 …

The Effects Of Hypoestrogenism On Rest And Acute Submaximal Exercise Metabolism Using A Gnrh Agonist Analogue Model., Sheri Anne Melton Jan 1997

The Effects Of Hypoestrogenism On Rest And Acute Submaximal Exercise Metabolism Using A Gnrh Agonist Analogue Model., Sheri Anne Melton

LSU Historical Dissertations and Theses

During menopause, many women experience weight gain which is mostly in the form of abdominal and upper body fat deposition. This phenomenon has been recognized as an independent predictor of cardiovascular disease in females. Other disease processes, such as diabetes, hypertension and some cancers, specifically, breast and esophageal have been linked to obesity. Thus, the occurrence of increased body fat is placing the postmenopausal female in jeopardy of a potential life-threatening position. The connection between the lack of estrogen seen in menopause and weight gain remains unclear, but studies have shown that estrogen status may affect carbohydrate and fat metabolism. …

Efficient Mapping Of Neural Network Models On A Class Of Parallel Architectures., Behnam Seyed Arad Jan 1997

Efficient Mapping Of Neural Network Models On A Class Of Parallel Architectures., Behnam Seyed Arad

LSU Historical Dissertations and Theses

This dissertation develops a formal and systematic methodology for efficient mapping of several contemporary artificial neural network (ANN) models on k-ary n-cube parallel architectures (KNC's). We apply the general mapping to several important ANN models including feedforward ANN's trained with backpropagation algorithm, radial basis function networks, cascade correlation learning, and adaptive resonance theory networks. Our approach utilizes a parallel task graph representing concurrent operations of the ANN model during training. The mapping of the ANN is performed in two steps. First, the parallel task graph of the ANN is mapped to a virtual KNC of compatible dimensionality. This involves decomposing …

Characterization Of Bean Eukaryotic Translation Initiation Factor 5: Cloning, Sequencing, And Structure-Function Studies., Zelpha Elizabeth Floyd

LSU Historical Dissertations and Theses

Translation initiation is emerging as one of the important mechanisms involved in regulation of gene expression and our understanding of this process in eukaryotes has greatly increased over the past twenty years. Research in translation initiation in plants has lagged behind efforts in the mammalian system and a number of the initiation factors have not been characterized. Eukaryotic initiation factor 5 (eIF5), the protein mediating hydrolysis of the eIF2-bound GTP and the subsequent formation of the 80S ribosome, is among the least characterized initiation factor in plants. This dissertation describes the cloning of the cDNA encoding eIF5 from a bean …

Identification Of The Physiological Role Of Carbonic Anhydrase Using The Antisense Technique, And, Investigation Of Its Transcriptional Regulation In Arabidopsis Thaliana (L.) Heynh., Hee Jin Kim Jan 1997

Identification Of The Physiological Role Of Carbonic Anhydrase Using The Antisense Technique, And, Investigation Of Its Transcriptional Regulation In Arabidopsis Thaliana (L.) Heynh., Hee Jin Kim

LSU Historical Dissertations and Theses

Carbonic anhydrase (CA, EC 4.2.1.1), catalyzes the interconversion of CO$\sb2$ and $\rm HCO\sb3\sp-$ in many organisms. The majority of CA activity in C3 leaves is in the chloroplast and expression of the chloroplast CA is regulated by light. To investigate the physiological role of the chloroplast CA, its expression was suppressed by insertion of a CA transgene in the antisense orientation in Arabidopsis thaliana (L.) Heynhold. Activity assays and immunoblots show that in five independent lines of antisense transgenic plants CA activity was strongly suppressed. All five independent lines died or grew poorly in the absence of sucrose whereas wild …
