Beef Producer Perferences For Various Livestock Revenue Protection Products: A Conjoint Approach, Deacue Fields Iii Jan 2002

Beef Producer Perferences For Various Livestock Revenue Protection Products: A Conjoint Approach, Deacue Fields Iii

LSU Doctoral Dissertations

The federal government has recently approved legislation to develop revenue insurance products that are affordable and user-friendly for livestock producers. The features of the products will be the ultimate determinant of product acceptance among producers. The objective of the study was to determine the relative importance of livestock revenue insurance product attributes as well as to identify the characteristics of beef cattle producers who prefer certain levels of a given product attribute. Conjoint analysis was utilized to determine the importance of selected attributes. Conjoint Designer was used to develop eleven hypothetical insurance products from four attributes with three levels each. …

Screening And Characterization Of Pathogenic Fungi For Possible Control Of Coptotermes Formosanus, Jianzhong Sun Jan 2002

Screening And Characterization Of Pathogenic Fungi For Possible Control Of Coptotermes Formosanus, Jianzhong Sun

LSU Doctoral Dissertations

Coptotermes formosanus was used as “bait” to isolate pathogenic fungi from soil. Fifteen pathogenic fungal isolates were obtained, all either Metarhizium anisopliae (six isolates) or Beauveria bassiana (nine isolates). There were no differences in numbers of fungal isolates from the three sampling locations. However, significantly more isolates were found in woodlands (eleven) than in pastures (four). Median lethal doses (LD50s) of these fungal species to C. formosanus were interspersed, indicating that fungal isolates rather than species had the greatest effect on virulence. In vitro growth characteristics were significantly correlated with virulence against termites, suggesting that fungal virulence might be predicted …

Multidemensional Goals Of Farmers In The Beef Cattle An Dairy Industries, Aydin Basarir Jan 2002

Multidemensional Goals Of Farmers In The Beef Cattle An Dairy Industries, Aydin Basarir

LSU Doctoral Dissertations

Farm firm decision making processes have long been of concern to agricultural economists. The concept of maximizing utility rather than profit is an important concept in multidimensional goal research. The prevalence of low or negative net returns in Louisiana beef and dairy production leads to the hypothesis that goals other than profit maximization compete strongly in producers' decisions. The objective of this study is to determine the hierarchy of goals that motivate beef and dairy producers and evaluate them in a multi-dimensional framework. Seven goals were evaluated in producer decision making: Maintain and Conserve Land, Maximize Profit, Increase Farm Size, …

Patterns Of Nucleotide Substitution Within And Among Mitochondrial Gene Regions In Sea Star (Leptasterias Spp), Adam Wayne Hrincevich Jan 2002

Patterns Of Nucleotide Substitution Within And Among Mitochondrial Gene Regions In Sea Star (Leptasterias Spp), Adam Wayne Hrincevich

LSU Doctoral Dissertations

In this study, 23 molecular lineages within the species-rich sea star genus Leptasterias subgenus Hexasterias section Camtschatica and an outgroup Leptasterias polaris were examined for patterns of mtDNA nucleotide sequence variation and evolution. Two separate regions of the mitochondrial genome were sequenced. The first region (549-bp) spanned the partial 3' ends of the 12s rRNA and 16s rRNA genes, complete tRNAs for glutamic acid and threonine, and complete putative control region. The second region (1644-bp) spanned approximately 85% of the 3' end of the cytochrome oxidase subunit I gene, complete tRNA for arginine and approximately 85% of the 5' end …

Effects Of Structural Marsh Management And Salinity On Sediments, Hydrology, Invertebrates, And Waterbirds In Marsh Ponds During Winter On The Gulf Coast Chenier Plain, Francois Bolduc Jan 2002

Effects Of Structural Marsh Management And Salinity On Sediments, Hydrology, Invertebrates, And Waterbirds In Marsh Ponds During Winter On The Gulf Coast Chenier Plain, Francois Bolduc

LSU Doctoral Dissertations

Compositions of wintering waterbird communities are dependent upon food accessibility (via water depth), biomasses and sizes of their invertebrate prey, which in turn are influenced by the hydrology and sediments of wetland habitats. The hydrology and sediments of marsh ponds on the Gulf Coast Chenier Plain probably are affected by structural marsh management (levees, water control structures and impoundments; SMM) and salinity; therefore, SMM and salinity ultimately may affect wintering waterbird communities. Accordingly, I measured sediment and hydrologic variables, biomasses and sizes of common aquatic invertebrates, and densities of common wintering waterbird species in ponds of impounded freshwater (IF), impounded …

Superfetation In Beef Cattle, Joel Andrew Carter Jan 2002

Superfetation In Beef Cattle, Joel Andrew Carter

LSU Doctoral Dissertations

Although superfetation has been reported in cattle and other species, there is considerable skepticism as to its existence due to the lack of clear evidence in these reports. Other explanations such as embryonic diapause or differential growth of twins have been suggested as more accurate descriptions of the cases reported as superfetation. The hypothesis of this study is that if a viable pregnancy can ensure maternal recognition in cattle, an asynchronous embryo can develop in a more chronologically advanced uterine environment. The objective was to produce superfetation by (1) ovulation induction and artificial insemination (AI) of pregnant cows and (2) …

American Transcendental Vision: Emerson To Chaplin, Bill R. Scalia Jan 2002

American Transcendental Vision: Emerson To Chaplin, Bill R. Scalia

LSU Doctoral Dissertations

Ralph Waldo Emerson's publication of Nature in 1836 began a process of creating a new condition of American thinking, severed from European cultural and intellectual influences. The subsequent lectures The American Scholar and The Divinity School Address furthered this process, calling for an original American literature. Emerson's writing called consistently for poets with the ability to "see" past the material, apparent world to the world of eternal forms, which shaped nature in accordance with a divine moral imperative. Through this connection, man-as-poet would discover God in himself. In short, Emerson effectively transferred divinity from Unitarian doctrine to the individual, thereby …

Treatment Acceptability For The Prevention Of Obesity And Type 2 Diabetes Mellitus: The Effects Of Ethnicity, Weight, And Genetic Predisposition, Jean Marie Thaw Jan 2002

Treatment Acceptability For The Prevention Of Obesity And Type 2 Diabetes Mellitus: The Effects Of Ethnicity, Weight, And Genetic Predisposition, Jean Marie Thaw

LSU Doctoral Dissertations

Childhood obesity and its associated health consequences, such as type 2 diabetes mellitus, have dramatically increased over the past 30 years, with the greatest rise in African-American female children and adolescents. Although current prevention efforts show promising results, recent genetic findings may soon expand treatment strategies to include new medications and gene therapies specifically designed to prevent the development of obesity and type 2 diabetes in children. However, little is known about the acceptability of these interventions. The primary aim of this study was to examine the hypothetical impact of genetic knowledge on treatment acceptability in the prevention of childhood …

Local, Regional, And Global Patterns Of Woodpecker (Picidae) Diversity: Ecological Explanations And Practical Applications, Alison Robinson Styring

LSU Doctoral Dissertations

This study explored foraging ecology in a guild of 13 woodpecker species found in the lowland rainforests of peninsular Malaysia. The data collected were used for two purposes: (1) to compare species from temperate and tropical woodpecker assemblages in an attempt to understand patterns of diversity, and (2) to determine the effects of logging on Malaysian woodpeckers. Ecological and morphological patterns of diversity were investigated in woodpeckers from tropical sites in Malaysia (Pasoh Forest Reserve and Sungai Lalang Forest Reserve) and Guatemala, and two temperate sites in North America. Multivariate analyses separated species into two ecomorphs: “conventional” - species that …

Study Of A Bacillus Circulans Chitin-Binding Domain By A Green Fluorescent Protein Binding Assay And Detection Of Lysozymes By Improved Zymograms, Markus Hardt Jan 2002

Study Of A Bacillus Circulans Chitin-Binding Domain By A Green Fluorescent Protein Binding Assay And Detection Of Lysozymes By Improved Zymograms, Markus Hardt

LSU Doctoral Dissertations

A fluorescent binding assay was developed to investigate the effects of site-directed mutagenesis on the binding affinity and binding specificity of the chitin-binding domain of chitinase A1 from Bacillus circulans WL-12. The chitin-binding domain (ChBD) was genetically fused to the N-terminus of the green fluorescent protein, GFP. The polyhistidine-tagged hybrid protein was expressed in Escherichia coli under the dose-dependent regulation of the araBAD promoter and purified using metal affinity-, chitin- or ion-exchange chromatography. Residues suggested to be involved in binding from previous three-dimensional studies were mutated and their contributions to binding and substrate specificity were evaluated by depletion assays. Purified …

Glycoprotein K Specified By Herpes Simplex Virus Type 1 Is Expressed On Virions As A Golgi Complex-Dependent Glycosylated Species And Functions In Virion Entry, T. P. Foster, G. V. Rybachuk, K. G. Kousoulas

Faculty Publications

To facilitate detection of glycoprotein K (gK) specified by herpes simplex virus, a 12-amino-acid epitope tag was inserted within gK domain III. Recombinant virus gKprotC-DIII, expressing the tagged gK, was isolated. This virus formed wild-type plaques and replicated as efficiently as the wild-type KOS virus in Vero cells. Anti-protein C MAb detected high-mannose and Golgi complex-dependent glycosylated gK within cells as well as on purified virions. The gK-null virus ΔgK (gK-/-) entered Vero cells substantially more slowly than the wild-type KOS (gK+/+), while ΔgK virus grown in complementing VK302 cells (gK-/+) entered with entry kinetics similar to those of the …

Fusobacteriosis In Captive Wild-Caught Pronghorns (Antilocapra Americana), J. F. Edwards, D. S. Davis, T. J. Roffe, F. Ramiro-Ibañez, P. H. Elzer Dec 2001

Fusobacteriosis In Captive Wild-Caught Pronghorns (Antilocapra Americana), J. F. Edwards, D. S. Davis, T. J. Roffe, F. Ramiro-Ibañez, P. H. Elzer

Faculty Publications

An outbreak of Fusobacterium necrophorum-induced septicemia occurred in a group of 40 captive wild-caught pronghorns (Antilocapra americana). Primary pododermatitis or necrotic stomatitis progressed to produce fatal septicemia with metastatic lesions in the forestomachs, lung, liver, and cecum in 38 of the animals. Two remaining animals were euthanatized because of chronic pododermatitis. Housing the animals in a pasture previously used by bovids and heavy rains with persistence of ground water pools in the pasture were contributing factors in the pathogenesis of this outbreak.

Diets Of Wild Versus Released, And Pen-Raised White-Tailed Deer In Southeastern Louisiana, Richard James Meyers Jul 2001

Diets Of Wild Versus Released, And Pen-Raised White-Tailed Deer In Southeastern Louisiana, Richard James Meyers

LSU Historical Dissertations and Theses

Twenty pen-raised white-tailed deer (Odocoileus virginianus) were released into mixed pine-hardwood forest habitat in southeastern Louisiana to compare their seasonal diets to the diets of the wild white-tailed deer population. Microhistological analysis was used to estimate the botanical composition of fecal pellet samples collected from both populations of deer over four consecutive seasons. Wild and pen-raised deer diets were found to be an average of 75.18% similar during the entire year of the study, and were significantly associated during all seasons (P < 0.001), indicating that all deer foraged on similar plant taxa in similar proportions regardless of season. Both populations of deer were found to be predominantly browsers during all seasons, with browse and fruit accounting for a yearly average of >55% of deer diets. Results from this study indicate that rehabilitated or translocated deer released into new environments …

Site-Directed Mutagenesis Of Atp Binding Residues Of Biotin Carboxylase: Insight Into The Mechanism Of Catalysis, Valerie Sloane, Carol Z. Blanchard, Frankie Guillot, Grover L. Waldrop

Faculty Publications

Acetyl-CoA carboxylase catalyzes the first committed step in fatty acid synthesis in all plants, animals, and bacteria. The Escherichia coli form is a multimeric protein complex consisting of three distinct and separate components: biotin carboxylase, carboxyltransferase, and the biotin carboxyl carrier protein. The biotin carboxylase component catalyzes the ATP-dependent carboxylation of biotin using bicarbonate as the carboxylate source and has a distinct architecture that is characteristic of the ATP-grasp superfamily of enzymes. Included in this superfamily are D-Ala D-Ala ligase, glutathione synthetase, carbamyl phosphate synthetase, N5-carboxyaminoimidazole ribonucleotide synthetase, and glycinamide ribonucleotide transformylase, all of which have known three-dimensional …

Investigation Of Heat Transfer Enhancement In Conceptual Two-Pass Channels For Gas Turbine Internal Cooling, Gautam Pamula May 2001

Investigation Of Heat Transfer Enhancement In Conceptual Two-Pass Channels For Gas Turbine Internal Cooling, Gautam Pamula

LSU Historical Dissertations and Theses

Modern gas turbines operate at high inlet temperatures due to which various components undergo severe thermal and mechanical stresses and fatigue. Suitable materials for withstanding such severe conditions are not available or are too expensive to manufacture. As a consequence, components need to be cooled to sustainable temperatures and efficient cooling strategies need to be developed. This study presents new internal cooling designs for turbine blades that eliminate the need for rib turbulators in internal passages producing significantly higher heat transfer enhancements. Detailed local heat transfer coefficient data of the proposed new designs (swirl generation using tangentially injected coolant from …

Group I Metabotropic Glutamate Receptors Are Expressed In The Chicken Retina And By Cultured Retinal Amacrine Cells, Kathryn M. Kreimborg, Martha L. Lester, Kathryn F. Medler, Evanna L. Gleason Apr 2001

Group I Metabotropic Glutamate Receptors Are Expressed In The Chicken Retina And By Cultured Retinal Amacrine Cells, Kathryn M. Kreimborg, Martha L. Lester, Kathryn F. Medler, Evanna L. Gleason

Faculty Publications

Glutamate is well established as an excitatory neurotransmitter in the vertebrate retina. Its role as a modulator of retinal function, however, is poorly understood. We used immunocytochemistry and calcium imaging techniques to investigate whether metabotropic glutamate receptors are expressed in the chicken retina and by identified GABAergic amacrine cells in culture. Antibody labeling for both metabotropic glutamate receptors 1 and 5 in the retina was consistent with their expression by amacrine cells as well as by other retinal cell types. In double-labeling experiments, most metabotropic glutamate receptor 1-positive cell bodies in the inner nuclear layer also label with anti-GABA antibodies. …

Of Manatees, Mangroves, And The Mississippi River: Is There An Estuarine Signature For The Gulf Of Mexico?, R. Eugene Turner

Faculty Publications

Important parameters of estuarine variability include morphology, flushing times, nutrient loading rates, and wetland: water ratios. This variability both reflects and disguises underlying relationships between the physics and biology of estuaries, which this comparative analysis seeks to reveal, using the Gulf of Mexico (GOM) estuaries as a starting point. A question used to focus this analysis is: are the GOM estuaries unique? The GOM receives the Mississippi River, a uniquely large, world-class river, which dominates the freshwater and nutrient inflows to the GOM continental shelf, whose margins include 35 major estuarine systems. These GOM estuaries have 28% and 41% of …

Expression Characteristics Of The Transfer-Related Kilb Gene Product Of Streptomyces Plasmid Pij101: Implications For The Plasmid Spread Function, G. S. Pettis, N. Ward, K. L. Schully Feb 2001

Expression Characteristics Of The Transfer-Related Kilb Gene Product Of Streptomyces Plasmid Pij101: Implications For The Plasmid Spread Function, G. S. Pettis, N. Ward, K. L. Schully

Faculty Publications

Intermycelial transfer of Streptomyces plasmid pIJ101 occurs prior to cellular differentiation and is mediated by plasmid functions that are also required for production of zones of growth-inhibited recipient cells (i.e., pocks) that develop around individual donors during mating on agar medium. Several other pIJ101 functions, including that of the kilB gene, whose unregulated expression on pIJ101 is lethal, are required for normal pock size and so have been postulated to mediate intramycelial spread of the plasmid throughout recipient cells. Using antibodies raised against a KilB fusion protein expressed in Escherichia coli, native KilB protein was detected throughout development of pIJ101-containing …
