Land Use And Water Quality Characterization Of Boeuf Basin, La, Joseph Wesley Leblanc
Land Use And Water Quality Characterization Of Boeuf Basin, La, Joseph Wesley Leblanc
LSU Master's Theses
The three primary goals of this project were to establish the ambient background of water quality in the Lake Boeuf basin in southeast Louisiana; establish land use patterns in the basin and the relation to water quality; and develop a preliminary plan to improve water quality through the use of best management practices and wetland assimilation. Urban and agricultural acreage borders the basin and runoff from these lands forces loadings of nutrients into the adjacent canals where they become channelized and ultimately exit the Boeuf Basin into Lac des Allemandes. From September 2007 until February 2008, water sampling occurred monthly …
Analysis Of Gas Dynamic Waves In Explosively Actuated Valves, Blaise H. Paul
Analysis Of Gas Dynamic Waves In Explosively Actuated Valves, Blaise H. Paul
LSU Master's Theses
A mathematical model is formulated for assessing quasi-one-dimensional gas dynamics occurring within axis-symmetric explosively actuated valves. The model describes complete valve operation and accounts for pressure-dependent explosive combustion within an actuator, compressible product gas flow within the actuator, through a small port, and into and within a gas expansion chamber. The gas dynamic waves induce piston motion at the terminal end of the expansion chamber which is needed for valve operation. The model is mathematically posed as an initial-boundary-value problem in terms of generalized coordinates to facilitate numerical computations on a domain that volumetrically expands due to combustion and piston …

The Lower Ninth Ward, New Orleans: Vestiges Of A Neighborhood, Adam N. Hess
LSU Master's Theses
The Lower Ninth Ward, New Orleans: Vestiges of a Neighborhood is a photo-documentary of the remnants of one of America’s most unique and culturally distinct neighborhoods. Three years after Hurricane Katrina devastated this neighborhood, it lies in ruin, slowly returning to nature. All that remains of the community that once occupied the Lower Ninth are the dilapidated buildings, the crumbling homes, and the small possessions left behind. For the past three years I have explored the Lower Ninth Ward, discovering the remains of a community rich in tradition, family, and religion. Through the use of black and white photographs and …
The Culture Of Conservative Protestantism And Income Inequality: A Multilevel Analysis, Skylar Craig Gremillion
The Culture Of Conservative Protestantism And Income Inequality: A Multilevel Analysis, Skylar Craig Gremillion
LSU Master's Theses
Despite major advances in equality of rights, women still earn less money than men. Social science researchers see sex-based income inequality as an issue of discrimination. While the problem has been identified, its causes are a matter of debate. In this study I offer one possible influence on this discrimination. I theorize that conservative Protestant culture has a strong effect on local norms and business practices. Those norms are a part of the institutional environment, and manifest themselves as allocative and valuative discrimination, keeping women out of high paying jobs or paying women in high skilled jobs less than men …
Molecular Determinants Of Kaposi's Sarcoma-Associated Herpesvirus Tumorigenicity, Haixia Kong
Molecular Determinants Of Kaposi's Sarcoma-Associated Herpesvirus Tumorigenicity, Haixia Kong
LSU Master's Theses
A conditional silencing system using anti-gB siRNAs was devised to investigate the structure and function of the KSHV gB. Transient co-transfection of plasmids constitutively expressing gB and anti-gB siRNAs in 293 cells substantially inhibited gB mRNA levels and protein production. Similarly, transient expression of siRNAs into the basal cavity-based lymphoma cells (BCBL-1) caused substantial reduction of gB transcription and protein synthesis. TaqMan real-time PCR and infectivity assays showed that gB was essential for virion egress and infectivity. Transfection of a codon-optimized gB not recognized by the anti-gB siRNAs, efficiently rescued virion egress and infectivity in BCBL-1 cells in the presence …

Effects Of Handedness On The Skull And Shoulder Bones, Michelle Lynn Osborn
Effects Of Handedness On The Skull And Shoulder Bones, Michelle Lynn Osborn
LSU Master's Theses
The unique configuration of the human clavicle and mastoid process suggests a functional connection between the head and shoulders in humans. The hypothesis in this study is that the clavicle, scapula and head form a functional complex and are interconnected by the sternocleidomastoid and trapezius muscles. In this complex, the trapezius muscles attach to the skull and become active when loads are carried. The sternocleidomastoid muscles are anchored to the clavicles; when loads are being carried, they act as guy ropes for the head, thereby keeping the head from being extended by the force of the contracting trapezius muscles. These …
Creatures Del Monte, Alejandro Arauz
Creatures Del Monte, Alejandro Arauz
LSU Master's Theses
To visually represent the multifaceted hybrid identity; a multidimensional artistic approach was necessary. I considered all the physical, psychological and cultural truths of my family. I explored our relationships, our behaviors and our responses as we simultaneously identify with the Latino and Anglo North American cultures and exist within its ever-changing parameters. Two streams of thought emerged in my artwork. One explores the characteristics and bi-cultural composition of my immediate family. The other looks at recalling past and distant members of my extended family as our points of origin while identifying the visible and invisible forces that shape our characters. …

The increasing computational and data requirements of scientific applications have made the usage of large clustered systems as well as distributed resources inevitable. Although executing large applications in these environments brings increased performance, the automation of the process becomes more and more challenging. The use of complex workflow management systems has been a viable solution for this automation process. In this thesis, we study a broad range of workflow management tools and compare their capabilities especially in terms of dynamic and conditional structures they support, which are crucial for the automation of complex applications. We then apply some of these …
Non-Industrial Private Forest Landowners And Us Home Center Retailers' Attitudes And Perceptions Of Forest Certification, Polwattage Kushil Perera
Non-Industrial Private Forest Landowners And Us Home Center Retailers' Attitudes And Perceptions Of Forest Certification, Polwattage Kushil Perera
LSU Master's Theses
The concept of forest certification, a relatively recent development in forestry, is based on the use of market-based incentives to encourage sustainable forest management practices. Since the majority of forests in US South are privately owned, certifying forests owned by non-industrial private forest (NIPF) landowners is an important issue. From the demand perspective of certification, pressure from non-governmental environmental organizations and consumer awareness has prompted major wood products retailers to state preferences for certified wood products. In the US, wood product demand in the retail home centers sector is second only to the home building industry. In addition, home center …
Quantification Of Tars And Particulates From A Pilot Scale, Downdraft Biomass Gasifier, Christopher Osita Akudo
Quantification Of Tars And Particulates From A Pilot Scale, Downdraft Biomass Gasifier, Christopher Osita Akudo
LSU Master's Theses
Alternative energy production through biomass gasification produces combustible gases, such as carbon monoxide, hydrogen, and methane. These gases can be used for generation of direct heat, electricity, or liquid fuels through the Fischer Tropsch process. However, a major limitation of the overall process is the purity of the generated synthesis gas. The tars and particulates generated in the gasification process constitute a major impediment to the commercial use of this technology because they may condense on valves, fittings, and therefore, hinder the smooth running of an engine. This research was aimed at developing a gas characterization and testing protocol, and …

Appealing To Heaven: The Significance Of Religion In John Locke's Advocacy Of Revolution, Glenn Andrew Moots
LSU Master's Theses
This research addresses the intersection of philosophy and theology in Locke’s philosophy, particularly his political philosophy. The justification for this inquiry is Locke’s use of the phrase “Appeal to Heaven” in the Second Treatise together with his advocacy of resistance in the Letter Concerning Toleration. The thesis begins with a brief survey of the relevant secondary literature and frames the intersection of theology and political philosophy. The thesis then seeks to justify the claim that Locke’s political ideas were motivated by religious concerns. This includes a close examination of An Essay Concerning Human Understanding, The Reasonableness of Christianity and his …
The Detection Of Malingered Mental Retardation In High- And Low-Cognitive Ability Individuals, Daniel Anthony Proto
The Detection Of Malingered Mental Retardation In High- And Low-Cognitive Ability Individuals, Daniel Anthony Proto
LSU Master's Theses
The detection of malingering is an area of research that has received increasing attention in recent decades. Neuropsychologists in particular are often asked to assess the validity of symptoms such as cognitive impairment due to brain injury or toxic chemical exposure. Additionally, given the decision of the U.S. Supreme court in Atkins v. Virginia (2002), incentive to feign mental retardation in order to avoid capital punishment has greatly increased. However, few measures of malingering detection have been thoroughly studied for their applicability to mentally retarded individuals, and for their ability to accurately distinguish between malingerers, normal controls, and individuals with …

Pet/Ct Detectability And Classification Of Simulated Pulmonary Nodules Using An Suv Correction Scheme, Andrew Nicholas Morrow
LSU Master's Theses
Positron emission tomography (PET) and computed tomography (CT) together are a powerful diagnostic tool, but imperfect image quality contributes to false positive and false negative diagnoses by an observer despite experience and training. This work investigated a PET standard uptake value (SUV) correction scheme, based on partial volume effect (PVE), on the classification of lesions as benign or malignant in PET/CT images. The correction scheme comprised several steps. The observer drew a region of interest (ROI) around the lesion using the CT dataset. The ROI was blurred with the assumed point spread function (PSF) of the PET scanner then re-sampled …

The Effectiveness Of Contextualization On Second Language Acquisition Using The Situational Discourse Semantic Model, Alice Marie Johnson
The Effectiveness Of Contextualization On Second Language Acquisition Using The Situational Discourse Semantic Model, Alice Marie Johnson
LSU Master's Theses
In traditional classrooms a second language is taught via thematic word sets, grammatical explanations, and patterned syntactic practice. This study compared the traditional teaching approach to a scaffolded teaching approach, consisting of words taught within a narrative context. Five fifth-grade students were taught Spanish as a second language during a ten-week intervention. Vocabulary learning and sentence generation were measured following each session, as well as a pre-posttest measure. Results showed that print was an important support used by participants in the traditional condition. However across time, vocabulary learning and sentence length increased significantly more in the scaffolded condition.

The Children's Coping Behavior Questionnaire: Development And Validation, Brittany Cornell Hernandez
The Children's Coping Behavior Questionnaire: Development And Validation, Brittany Cornell Hernandez
LSU Master's Theses
Coping is defined as the actions and cognitions used to manage stressful demands. As children develop, coping becomes more refined and situation-specific. Children’s coping styles have been found to relate to distress and adjustment. Despite the importance and implications of children’s coping responses, there is no accepted standard in measuring children’s coping. Past research has had to utilize the few measures in existence, despite possible psychometric inadequacies. Therefore, the purpose of this study was to develop a psychometrically sound self-report measure of coping in children and adolescents. After initial item generation, pilot testing, and item elimination, the data were factor …
