Can I Play Too? A Look At Minor Party Entrance And Success In U.S. Gubernatorial Elections, Jay Douglas Ducote
LSU Master's Theses
New minor political parties and their candidates face many challenges. Most of challenges have been examined on the national level in the previous literature. By examining ballot access laws and campaign finance regulations in all 50 U.S. states, this thesis argues that differences in the restriction to ballot access and campaign finance laws account for some of the variation in the number of new minor party candidates who run for governor in each state as well as the percentage of the vote they receive. Using a coding for ballot access laws and campaign finance stringency, as well as several control …

Evaluation Of Compliance With The Long Term 1 Enhanced Surface Water Treatment Rule, Racquel Rena Douglas
LSU Master's Theses
Cryptosporidium is a common protozoan parasite that causes cryptosporidiosis, a severe gastrointestinal disease. Currently, there is no antibiotic available to treat the disease. Cryptosporidium has been responsible for several waterborne disease outbreaks in the United States. The largest cryptosporidiosis outbreak in United States history occurred in Milwaukee, Wisconsin in spring 1993. The vulnerability of the United State drinking water supply to waterborne disease outbreak is still prevalent nearly 15 years after the Milwaukee outbreak. In order to effectively control Cryptosporidium, the EPA has strengthened the regulations on turbidity control for filtration performance by implementing the Long Term 1 Enhanced Surface …

Characterization Of A Virulence Related Hypothetical Protein In Edwardsiella Ictaluri, Ildiko Katalin Polyak
Characterization Of A Virulence Related Hypothetical Protein In Edwardsiella Ictaluri, Ildiko Katalin Polyak
LSU Master's Theses
Although the biochemical characterization of E. ictaluri, the subsequent disease progression of enteric septicemia of catfish (ESC), and the associated pathologic lesions are well characterized, the mechanism of invasion of E. ictaluri into a susceptible host is poorly understood. Identification and confirmation of virulence factors and associated genes of E. ictaluri is crucial to elucidating the pathogenesis of this important disease. A signature tagged mutagenesis (STM) study conducted by Thune et al. (2006) identified 50 E. ictaluri clones with transposon insertions in genes potentially involved in pathogenesis. A specific STM mutant, 233PR, carrying a transposon insertion in a gene encoding …

Overall the museums took surprisingly different approaches to designing their exhibits. The American Museum of Natural History gave a general overview of Japan and China. The Mobile Museum of Art focused only on pottery and the Morikami Museum focused on the Japanese immigrants that settled in Del Ray Beach. Differences and similarities of these museums and what these exhibits tell the viewer about the two …
Mechanism Of Intraspecific Toxin Inhibition In Aspergillus Flavus, Changwei Huang
Mechanism Of Intraspecific Toxin Inhibition In Aspergillus Flavus, Changwei Huang
LSU Master's Theses
Atoxigenic Aspergillus flavus was demonstrated by others as a promising biocontrol agent to minimize preharvest aflatoxins in susceptible crops. But the mechanism was unclear. A filter insert-well plate system was used to study the mechanism in lab. There was no inhibition when toxigenic A. flavus isolate 53 and inhibitory atoxigenic isolates were separated by 0.4 µm membrane, approximately 50% inhibition occurred when separated by 12 µm membrane, and complete inhibition occurred when a 74 µm membrane was used. This result suggested that touching or close physical interaction is needed for toxin inhibition and the nutrient competition hypothesis was not supported. …

The Role Of Toll-Like Receptor 7 In The Neuropathogenesis Of Retrovirus Infection In Neonates, Stephanie Diane Lewis
The Role Of Toll-Like Receptor 7 In The Neuropathogenesis Of Retrovirus Infection In Neonates, Stephanie Diane Lewis
LSU Master's Theses
Viral infections of the central nervous system (CNS) in infants are rare; however, they are associated with high morbidity and mortality rates. These virus infections often induce strong innate immune responses in the brain including: the production of cytokines and chemokines, the activation of astrocytes and microglia and the recruitment of macrophages. Innate immune responses are often initiated by toll-like receptors (TLR). Several studies have demonstrated that toll-like receptor 7 (TLR7) can be stimulated by single-stranded RNA from multiple viruses. In the current study, we examined the mechanism by which TLR7 contributes to neuroinflammation in the neonatal brain using a …

Moving Towards A Very Long Engagement: The Effects Of Interactivity On Prolonging Engagement With Online Movie Advertisements, Jesse T. Hoggard
Moving Towards A Very Long Engagement: The Effects Of Interactivity On Prolonging Engagement With Online Movie Advertisements, Jesse T. Hoggard
LSU Master's Theses
An experiment with 421 participants aged 18-45 was conducted to measure the effects of interactivity in an online movie advertising setting, and the effects of interactivity on consumer engagement and other brand metrics. Results from a post-test survey revealed insight into participants’ perceived level of interactivity, and reflected varying levels of attitude towards ad messages, ad recall, mood, and factors in purchasing habits. Results suggested that while interactivity can sometimes hinder advertising recall rates, it can also increase positive attitudes toward the advertisement, click-through rate, intent to purchase, and mood. Practical implications and suggestions for further research are discussed.
Effects Of Pre- And Postharvest Calcium Supplementation On Longevity Of Sunflower (Helianthus Annuus Cv. Superior Sunset), Sergio J. Sosa Nan
Effects Of Pre- And Postharvest Calcium Supplementation On Longevity Of Sunflower (Helianthus Annuus Cv. Superior Sunset), Sergio J. Sosa Nan
LSU Master's Theses
The sunflower is one of the most important specialty cut flowers produced. Sunflowers have a short and variable postharvest longevity that is dependent upon cultivar. Research in postharvest physiology of cut flowers indicates that calcium (Ca) may be involved in delaying flower senescence by postponing cell membrane degradation. Cut flowers with intact cell membrane structure and function maintain their water balance and last longer. This study was developed to determine the effects of Ca supplementation on longevity of fresh cut sunflowers. The cultivar ‘Superior Sunset’ was used in this study; the sources of Ca were Ca(NO3)2, CaCl2 or a chelated …

Pre-Treatment Of Dynamically Varying Waste Gas Concentrations Using Activated Carbon Prior To Biofiltration: Effect Of Cycle Length On Degree Of Load Equalization, Kodi L. Collins
LSU Master's Theses
Dynamically varying waste gas concentrations pose challenges to the operation and design of air pollution control techniques such as biofilters. Although design approaches are becoming well established for biofilters treating gases containing VOC concentrations that are constant as a function of time, many industrial processes emit gas streams contaminated with volatile organic compounds at concentrations that fluctuate with time. Application of an effective load equalization technique could eliminate some challenges associated with fluctuating pollutant concentrations. Recent research has demonstrated that granular activated carbon (GAC) can serve as a passively controlled system to provide load-equalization as a pre-treatment prior to biofiltration. …
Chemical Ecology, Fungal Interactions And Forest Stand Correlations Of The Exotic Asian Ambrosia Beetle, Xylosandrus Crassiusculus (Motschulsky) (Curculionidae), Eric Paul Ott
LSU Master's Theses
Increasing evidence of non-indigenous ambrosia beetles aggressively attacking hosts in their new environment in the United States has led to concern over the potential for damage to urban trees, nurseries, orchards, and forests. A novel technique of flooding host trees was devised to stimulate ambrosia beetle attacks, with ambrosia beetle attraction peaking four days following flooding. In-situ sampling identified significant differences in the composition, quantity and point of release (leaf or bole) of volatiles emitted by the flooded and non-flooded trees. Coupled gas chromatography electroantennographic detection revealed olfactory sensitivity by the ambrosia beetle Xylosandrus crassiusculus (Motschulsky) to 29 of these …

Revelations From "Cheesecake Manor": Agatha Christie, Detective Fiction, And Interwar England, Carron Stewart Fillingim
Revelations From "Cheesecake Manor": Agatha Christie, Detective Fiction, And Interwar England, Carron Stewart Fillingim
LSU Master's Theses
For too long standard interwar histories have portrayed the interwar years as a period marked by failure, instability, depression, and volatility. Instead, rising living standards, the narrowing of socioeconomic disparities, expanded avenues of social welfare, increased leisure time, and mass consumerism resulted in an altogether peaceful, healthier, stable, and increasingly affluent England. Out of these rising economic improvements emerged forms of mass entertainment, including popular fiction. Cheaper paper and printing methods, rising literacy, faster distribution methods, new forms of advertising, and the expansion of public libraries led to the creation of a mass readership across England. For the first time, …

Reinventing The Sword: A Cultural Comparison Of The Development Of The Sword In Response To The Advent Of Firearms In Spain And Japan, Charles Edward Ethridge
LSU Master's Theses
Swords have been used throughout history as weapons of war, as symbols of power and wealth and as national and religious icons. Unlike other weapons however, the sword did not simply fade into the background as technological improvements caused the martial value to lessen. The primary purpose of this paper is to look at the development of the sword as an object of art, specifically in the countries of Spain and Japan, after the invention of the firearm. A brief history of the development of the sword from the earliest manifestations through the Iron Age is provided as way of …
A Liquid Lens Based On Electrowetting, Jihwan Park
A Liquid Lens Based On Electrowetting, Jihwan Park
LSU Master's Theses
A primary goal of this work is to develop and characterize a novel liquid lens based on electrowetting. A droplet of silicone oil confined in an aqueous solution works as a lens. Electrowetting then controls the shape of the confined silicone oil, and the focal length may be varied upon an applied electric potential. The planar lens design is employed for easy integration of a lens system into a microfluidic device. The achievements of this work are to develop an electrowetting-based planar liquid lens without an off-the-plane electrode structure and to demonstrate the planar liquid lens with variable focal length …
Oil Bypassing By Water Invasion To Wells: Mechanisms And Remediation, Juan Carlos Hernandez
Oil Bypassing By Water Invasion To Wells: Mechanisms And Remediation, Juan Carlos Hernandez
LSU Doctoral Dissertations
This study addresses oil bypassing caused by water invasion to wells in edge and bottom water-drive oil reservoirs – a significant problem worldwide. It is shown that the amount of by-passed (not recovered) oil is significant and could be predicted analytically and reduced by modifying well’s completion. A large statistical sample from the population of possible reservoir-well systems with edge and bottom-water has been created theoretically using several databases of actual reservoirs properties worldwide. Dimensional analysis allowed converting reservoir properties distributions into dimensionless group distributions. Then, the amount of by-passed oil was correlated with the dimensionless groups using designed experiments …

Responses Of Respiratory System Cells In Vitro And In Vivo To Petrochemical Combustion-Derived Ultrafine Particles, Gleeson Murphy, Jr.
Responses Of Respiratory System Cells In Vitro And In Vivo To Petrochemical Combustion-Derived Ultrafine Particles, Gleeson Murphy, Jr.
LSU Doctoral Dissertations
Environmental contamination with airborne particles has been a human health concern for many years. Epidemiologic studies in urban communities have linked ambient particle exposure to various health effects, including chronic obstructive pulmonary disease, lung cancer, and several cardiovascular disease conditions. The pathogenesis of these conditions with respect to ambient particle exposure is complex because ambient particles are complex in composition. The particles vary greatly in origin, size, surface area, and elemental composition; and a given particle type, such as those generated by petrochemical (gasoline, diesel, industrial substrate) combustion, may be coated with many other compounds, including polynuclear aromatic hydrocarbons (PAHs). …

The Spectral And Photophysical Characterization Of Water Solubilizing Metal Phthalocyanines For Highly Sensitive Detection In Biological Studies, Vera Tamisha Verdree
The Spectral And Photophysical Characterization Of Water Solubilizing Metal Phthalocyanines For Highly Sensitive Detection In Biological Studies, Vera Tamisha Verdree
LSU Doctoral Dissertations
Efforts to improve the technology for DNA analyses stimulated the work presented here to develop a series of fluorescent probes that would aid in the increased multiplexing capabilities allowing the ability to detect multiple targets in a single measurement. Typically, spectral discrimination has been used to identify each DNA fragment in sequencing or diagnostic applications by means of unique emission properties from several labeling dyes. This has been accomplished with labels that fluoresce in the visible region. The limitations with these dyes is the broad emission profile making discrimination difficult, high intrinsic biological fluorescence and structural differences of the dyes …

Soliciting Desire: The Ad-Man As Narrative Negotiation Between Art, Desire, And Consumer Capitalism In Twentieth-Century Novels, Jessica Mckelvie Kemp
Soliciting Desire: The Ad-Man As Narrative Negotiation Between Art, Desire, And Consumer Capitalism In Twentieth-Century Novels, Jessica Mckelvie Kemp
LSU Doctoral Dissertations
My dissertation identifies ways in which novelists have used an ad-man protagonist as means to investigate the social and psychological implications of advertising in the twentieth and twenty-first centuries. Soliciting Desire takes as its primary subjects H.G. Wells’s Tono-Bungay, Theodore Dresier’s The “Genius,” Frederick Wakeman’s The Hucksters, Jonathan Dee’s Palladio, and William Gibson’s Pattern Recognition and demonstrates that the ad-man character’s particular constellation of traits provides a rich vehicle for fictional explorations of desire and subjectivity as they are formed in relation to ideologies of consumer capitalism and art. Guided by Theodor Adorno and Walter Benjamin’s theories of cultural/ capitalist …
