Comparative Genomics, Transcriptome Analysis And Characterization Of Selected Regulatory Genes Of Burkholderia Glumae, Felix Francis
Comparative Genomics, Transcriptome Analysis And Characterization Of Selected Regulatory Genes Of Burkholderia Glumae, Felix Francis
LSU Master's Theses
Burkholderia glumae is the primary causal agent of bacterial panicle blight of rice, which is becoming a major threat to global rice production. The genome of a highly virulent B. glumae strain, 336gr-1 that was isolated from rice in Louisiana, was sequenced to better understand the genome-scale characteristics, particularly that of its pathogenicity. Comparative genomic analyses with another strain, BGR1 that was isolated from Korea, revealed several unique regions present in the genomes of these two geographically separated phytopathogenic bacteria. Genome plasticity, primarily caused by a horizontal gene transfer, was observed in these closely related strains of Burkholderia that are …
Oil-Mediated Mortality And Induced Behavioral Modifications Of Coastal Insects, Benjamin Jacob Adams
Oil-Mediated Mortality And Induced Behavioral Modifications Of Coastal Insects, Benjamin Jacob Adams
LSU Master's Theses
The Deepwater Horizon oil spill affected over one thousand kilometers of the southeastern United States’ coast in the Gulf of Mexico especially Louisiana’s salt marshes. These marshes are a vital part of the state’s economy and coastal ecology; however, the insects residing in this area remain largely unstudied. The goal of my project was to answer specific questions arising from two ongoing investigations of the insects in the oiled marshes. I sampled insects using sweep nets and insect vacuums to determine the most efficient technique to use in the marsh, compared insects collected in oiled and non-oiled marshes, and completed …
Integrated Management Of The Red Imported Fire Ant In Pastures, William Sullivan Hilbun
Integrated Management Of The Red Imported Fire Ant In Pastures, William Sullivan Hilbun
LSU Master's Theses
The effects and interactions of chemical, cultural, and biological control of red imported fire ant (RIFA) populations were evaluated in two replicated studies in pastures. The first study was conducted from 2005 through 2007 in Washington parish, Louisiana (WP) where the biological control Psuedacteon tricupsis phorid flies were present and at the LSU AgCenter St. Gabriel Research Station in St. Gabriel, Louisiana (SG) where Psuedacteon tricuspis flies were absent. The second study was conducted from May 2009 to May 2010 at St. Gabriel in the presence of phorid flies. In both studies, RIFA population indices in sites treated with methoprene …
Repeatability Of Prolactin Responses To Sulpiride In Mares And Geldings And The Effect Of Pergolide And Cabergoline, Rebekah C. Hebert
Repeatability Of Prolactin Responses To Sulpiride In Mares And Geldings And The Effect Of Pergolide And Cabergoline, Rebekah C. Hebert
LSU Master's Theses
Four experiments were conducted in an effort to develop a method, based on prolactin secretion, for assessing the efficacy and duration of activity of dopaminergic agonists for the treatment of pituitary pars intermedia dysfunction (PPID) in horses. In the first experiment, prolactin response to a low dose of the dopamine antagonist, sulpiride, was generally repeatable in estrogen-primed geldings in winter over 8 every-other-day challenges. It was concluded that estrogen-primed, sulpiride-challenged geldings in winter could serve as a model for the study of potential dopaminergic drugs for the treatment of PPID in horses. The second experiment was performed in the summer …
Economic And Attitudinal Perspectives Of The Recreational For-Hire Fishing Industry In The U.S. Gulf Of Mexico, Michelle Savolainen
Economic And Attitudinal Perspectives Of The Recreational For-Hire Fishing Industry In The U.S. Gulf Of Mexico, Michelle Savolainen
LSU Master's Theses
Socioeconomic and policy information is important to fisheries management in order to assess potential social and economic impacts of proposed fishing regulations. Previous surveys which collect this type of data for the recreational for-hire (RFH) fishing industry in the U.S. Gulf of Mexico were conducted in 1987 and 1997. The third Gulf-wide survey was conducted in 2010 to update the socioeconomic and policy data available on the RFH industry. More specifically, the survey collected captain, vessel, and trip characteristics, firm and trip financial data, targeted species, and opinions on policy issues and hurricane impacts. State license information indicated that 3,315 …
The Effects Of Spinosad On Culex Quinquefasciatus (Diptera: Culicidae) And Non-Target Insect Species, Owen Mcbride Jones
The Effects Of Spinosad On Culex Quinquefasciatus (Diptera: Culicidae) And Non-Target Insect Species, Owen Mcbride Jones
LSU Master's Theses
Spinosad is a relatively new insecticide with a unique mode of action that is being evaluated for control of larval mosquitoes. Whereas a number of toxicological studies have measured effects of spinosad on various mammals, fish, birds, and terrestrial arthropods, fewer studies have been conducted on the effects of spinosad on non-target aquatic insect species. Such studies are important as these species might be found in the same environments as mosquito larvae targeted for control. A neighborhood pond was surveyed to find a representative species of mosquito as well as other common aquatic insects with which to examine susceptibility to …
Commuting Patterns And Labor Markets: A New Regional Classification For Louisiana, Deepa Acharya
Commuting Patterns And Labor Markets: A New Regional Classification For Louisiana, Deepa Acharya
LSU Master's Theses
Regional classification and labor market study form an important part of any regional development efforts. Successful formation and implementation of developmental policies for a region requires a sound knowledge of the labor market situation and socioeconomic background of the region, which in turn leads ultimately to regional welfare. We find literature in the area of regional classification to be very inadequate. This study classifies Louisiana using a clustering approach in two different ways. First of all, Ward’s method has been used to classify Louisiana into labor markets based on two-way commuting flow between the parishes. Eight geographical clusters are formed …
Three Essays On Modeling Economic And Fiscal Change For Communities Under Disequilibrium Following Natural Disasters, Arun Adhikari
Three Essays On Modeling Economic And Fiscal Change For Communities Under Disequilibrium Following Natural Disasters, Arun Adhikari
LSU Doctoral Dissertations
Regional economists and policy makers are interested in forecasting economic changes that are likely to take place at local and state levels after exogenous shocks to an economy; that is, create disequilibrium conditions in terms of supply and demand. Impacts of such shocks could be observed at the level of employment, unemployment, commuting patterns, assessed property values, property and sales taxes and local level of expenditures in several categories. The objective of the first essay was to model the employment change decompositions of different effects in two major industries using a shift share analysis technique in context of Louisiana parishes …
Development Of An Estradiol-Dopamine Anagonist Protocol For Inducing Ovulation In Seasonally Anovulatory Mares, Pamela Boliew Mitcham
Development Of An Estradiol-Dopamine Anagonist Protocol For Inducing Ovulation In Seasonally Anovulatory Mares, Pamela Boliew Mitcham
LSU Doctoral Dissertations
Five experiments were conducted to assess potential improvements in a protocol for inducing ovulation in seasonally anovulatory mares based upon estradiol pretreatment followed by dopamine antagonist injection. The first experiment compared various doses of estradiol cypionate (ECP) and domperidone (in biodegradable microparticles), as well as additions and deletions to the protocol. It was concluded that as little as 75 mg ECP and as little as 1.5 g of domperidone could be used with success, but that both components were required. In the second experiment, timing of the injection (1, 6, or 11 days apart) and ECP dose were assessed. It …
Assessment Of Stink Bug Feeding Damage In Louisiana Soybean: Use Of A No-Choice Feeding Field Protocol, Jessica Leigh Parker
Assessment Of Stink Bug Feeding Damage In Louisiana Soybean: Use Of A No-Choice Feeding Field Protocol, Jessica Leigh Parker
LSU Master's Theses
Numerous arthropods are pests of soybean in the subtropical environment of Louisiana. The most important pod-feeding guild includes a complex of stink bugs (Hemiptera: Pentatomidae). One of these species, redbanded stink bug (Piezodorus guildinii [Westwood]), has emerged as a significant pest in Louisiana soybean. Currently, limited information is available describing soybean plant injury from this pest in the United States or compares injury relative to native stink bugs. Therefore, a field protocol was modified to assess injury to soybean seeds. Studies conducted in Louisiana during 2009-2011 used procedures to isolate the effects of infestation duration (24-96 h after infestation [HAI]) …
Dynamics Of The Sweetpotato Potyvirus Aphid Pathosystem In Louisiana, Everlyne Nafula Wosula
Dynamics Of The Sweetpotato Potyvirus Aphid Pathosystem In Louisiana, Everlyne Nafula Wosula
LSU Doctoral Dissertations
Sweetpotato potyviruses [Sweet potato feathery mottle virus (SPFMV), Sweet potato virus G (SPVG) and Sweet potato virus 2 (SPV2)] commonly infect sweetpotato and weedy morning glories in the USA. These viruses are transmitted in a non-persistent manner by various aphid species and cause up to 15% yield loss. Sweetpotato is vegetatively propagated, and in the USA growers are supplied with virus tested propagation material to minimize impact of viruses. However the rapid re-infection of these materials with viruses warranted further studies to determine factors that influence the epidemiology of these viruses. The objectives of this study were: (i) to determine …
Three Essays On Technology Adoption And The Roles Of Off-Farm Labor, Human Capital, And Risk In Contemporary Us Agriculture, Hiroki Uematsu
Three Essays On Technology Adoption And The Roles Of Off-Farm Labor, Human Capital, And Risk In Contemporary Us Agriculture, Hiroki Uematsu
LSU Doctoral Dissertations
Agriculture can be defined as the domestication and farming of plant and animal species to produce food and fiber products. Our society is fundamentally dependent on agriculture as it is the primary source of nutrients essential to human activities. Historically, the introduction of agriculture and technological development thereafter drastically changed the way human civilization has evolved into what it is today. New technologies allow farmers to produce more outputs with fewer inputs. Saved resources from agricultural production, such as land, labor and time, were used elsewhere to produce other goods and services that enrich the quality of our life. The …
Three Essays On The Efficiency Of Rural Hospitals In The United States, Iustin Cristian Nedelea
Three Essays On The Efficiency Of Rural Hospitals In The United States, Iustin Cristian Nedelea
LSU Doctoral Dissertations
The Critical Access Hospital (CAH) Program was created in response to the dramatic deterioration of financial conditions and the potential threat of closure of small rural hospitals under the Prospective Payment System (PPS). CAHs receive cost-based reimbursement for services provided to Medicare patients in exchange for accepting a number of restrictions. The PPS, which pays a fixed price per case, provides an incentive for hospitals to reduce costs and increase efficiency. In the first essay, I examine the impact of conversion to CAH status on hospital efficiency. The estimated results show that CAHs are less cost and allocatively efficient than …
Lentiviral Transduction Of Epigenetically Modified Bovine Adult Stem Cells, Meredith Kathleen Addison
Lentiviral Transduction Of Epigenetically Modified Bovine Adult Stem Cells, Meredith Kathleen Addison
LSU Master's Theses
Bovine adipose-derived stem cells (ADS), a form of adult stem cells, are somatic cells that have similar characteristics of embryonic stem (ES) cells. Bovine ADS cells possess multipotent capabilities and have been found to express pluripotency genes associated with ES cells. The unique properties of ADS cells make them a desirable source for reprogramming experiments. The goal of reprogramming experiments is to transform somatic cells from a differentiated state to a pluripotent state. When somatic cells reprogram, there are certain epigenetic changes or modifications that must occur in order to successfully reprogram the nucleus. Epigenetic modifications will change the chromatin …
Comparison Of Epididymal And Ejaculated Sperm Collected From The Same Holstein Bulls, Michael A. Stout
Comparison Of Epididymal And Ejaculated Sperm Collected From The Same Holstein Bulls, Michael A. Stout
LSU Doctoral Dissertations
Salvaging of epididymal sperm from injured or deceased animals allows for the propagation of favorable traits from endangered or genetically superior males. Techniques developed in domestic species can also serve as the foundation for the collection, cryopreservation and utilization of epididymal sperm in exotic breeds. The need to preserve and utilize epididymal sperm, in the most efficient manner, is of the utmost importance. In a series of experiments, ejaculated and epididymal sperm from the same four mature, fertile, Holstein bulls were collected, cryopreserved, cultured and used for in vitro fertilization. In Experiment I, epididymal sperm was found to have higher …
Reduced Protein For Late-Lactation Dairy Cows, Andre De Barros Duarte Pereira
Reduced Protein For Late-Lactation Dairy Cows, Andre De Barros Duarte Pereira
LSU Master's Theses
Excess protein in dairy cattle diets unnecessarily increases the cost of production and may contribute to environmental pollution. The objective of this research was to evaluate the effect of feeding dairy cows with two levels of dietary protein on animal performance and manure characteristics. Two experiments were carried out with 24 lactating dairy cows each. Experiment 1 was corn silage based and had a control TMR (HP1) estimated to contain 16.5% CP with SBM and treatment TMR (LP1; 13.5% CP) using DDGS and rumen protected Lys and Met. Experiment 2 was ryegrass haylage based and had a control TMR (HP2) …
Effect Of Surfactants On The Pretreatment Of Sugarcane Bagasse With Dilute Ammonia, Shuo Cao
Effect Of Surfactants On The Pretreatment Of Sugarcane Bagasse With Dilute Ammonia, Shuo Cao
LSU Master's Theses
Lignocellulosic biomass is composed of cellulose, hemicellulose and lignin which are not readily available for conversion in their native form. It is widely accepted that lignin acts as the “glue” that binds cellulose and hemicellulose, giving rigidity and resistance to lignocellulose. The use of non-ionic surfactants during pretreatment can help alter the structure of lignocellulosic biomass to improve cellulose digestibility and ethanol yields. Tween 80, Tween 20, PEG 4000, or PEG 6000 was used with ammonium hydroxide for the pretreatment of sugarcane bagasse. The pretreatment was carried out by mixing sugarcane bagasse, ammonium hydroxide (28% v/v) and water at a …
