Concentration And Detection Of Hepatitis A Virus And Its Indicator From Seawater, Jiemin Cormier Jan 2013

Concentration And Detection Of Hepatitis A Virus And Its Indicator From Seawater, Jiemin Cormier

LSU Doctoral Dissertations

Hepatitis A virus (HAV) infection is the leading worldwide cause of acute viral hepatitis, and its outbreaks often occur from fecal contaminated shellfish. HAV is extremely stable in the environment and can survive 3~10 months in water. In addition, HAV can be bio-concentrated by shellfish by as much as 100 fold from fecal contaminated waters. Bacteriophage MS2 is used widely as a surrogate for HAV, and its presence has been proven to be a reliable indication of the presence of HAV. A rapid detection of viral contamination in water environments can prevent economic loss and can identify the source of …

A Calvinist View Of Visual Art In Seventeenth-Century Holland : The Iconography Of Esther In Post-Reformation Dutch Painting, Sarah Grafton Peaster Jan 2013

A Calvinist View Of Visual Art In Seventeenth-Century Holland : The Iconography Of Esther In Post-Reformation Dutch Painting, Sarah Grafton Peaster

LSU Master's Theses

The Book of Esther, found in the Old Testament, has been represented in a variety of ways throughout history. In a sweeping tale of love, honor, and sacrifice, the Jewish maiden queen, Esther, is a heroine to the oppressed. Dutch Protestants in the Golden Age felt a kinship to this subject, particularly after the Protestant Reformation and the new religious freedom gained in Holland during the sixteenth century, which continued in the seventeenth century. These men and women saw many parallels between Esther’s experience and their own, both as the covenant people of God and as the remnant preserved by …

Studying Mechanisms Of Ionizing Radiation Resistance In Bacteria: Evidence For Multiple Pathways, Kathiresan Selvam Jan 2013

Studying Mechanisms Of Ionizing Radiation Resistance In Bacteria: Evidence For Multiple Pathways, Kathiresan Selvam

LSU Doctoral Dissertations

Our lab created ionizing radiation (IR) resistant populations of E. coli MG1655 through twenty cycles of exposure to IR and outgrowth. To identify the genetic alterations responsible for increased IR tolerance, a total of seven isolates from the evolved final population were re-sequenced. However, the individual isolates sequence analysis revealed wide variety of unique genomic alterations with little overlap between the seven isolates and therefore, did not reveal the clear picture of the mutations responsible for IR resistance. Our current research focused on distinguishing the relevant mutations from the non-relevant mutations that contribute to IR resistance by using two methods: …

Her Voice Has Life: The Myth Of Echo In Psychoanalysis And Deconstruction, And The Acoustic Vision Of A New Subjectivity, Christian Lacroix Mecham Jan 2013

Her Voice Has Life: The Myth Of Echo In Psychoanalysis And Deconstruction, And The Acoustic Vision Of A New Subjectivity, Christian Lacroix Mecham

LSU Master's Theses

Taking seriously Ovid’s claim that Echo’s voice has life, this thesis examines the use of the myth of Echo and Narcissus, as presented in Ovid’s Metamorphoses, in 20th century literature, philosophy, and psychoanalysis, especially as to how it pertains to the creation of the human subject. I argue in favor of John Hollander’s restoration of the trope of metalepsis, and show how that trope is connected to a variety of topics, including, but not limited to, the imagery of echo in Mark Z. Danielewski’s novel House of Leaves; how the myth relates to the Freudian notions of primary and secondary …

An Etho-Conventional Decision-Making Model For Sport Managers, Adam G. Pfleegor Jan 2013

An Etho-Conventional Decision-Making Model For Sport Managers, Adam G. Pfleegor

LSU Doctoral Dissertations

The need for an ethically conscious sport management workforce is evident in contemporary athletics (Simon, 2010). As the complexities of regulations continue to increase, the intricacy of ethical-decisions faced by managers similarly intensifies. Interestingly, future sport managers are rarely prepared with appropriate ethical decision-making education (Malloy & Zakus, 1995). This lack of education is problematic due to the far-reaching implications that managerial decision-makers have on firms. The aim of this investigation was to develop a novel ethical decision-making model for sport managers that can be practically implemented to resolve ethical dilemmas that they may encounter on a daily basis. The …

To Speak As A Human, A Modern And As An American : Blues Rhetoric In Cornel West's Prophetic Pragmatism, Raquel M. Robvais

LSU Master's Theses

This thesis examines Cornel West’s description of the human condition and the works of art produced in three particular ways. First, there is being human which is a universal condition that speaks to all people and their struggles in the face of death and fallibility. Second, there is the condition of being modern, which speaks to people in a particular age in which power must be challenged with intelligence. Third, there is the idea of being American, which is to confront historical legacies of injustice through political action and agency. Rhetoric speaks to these existential crises and draws its resources …

Poultry Litter Ash As A Phosphorus Source For Greenhouse Crop Production, Daniel Evan Wells Jan 2013

Poultry Litter Ash As A Phosphorus Source For Greenhouse Crop Production, Daniel Evan Wells

LSU Doctoral Dissertations

Phosphorus (P) is an essential nutrient for all life forms, including plants, but is a limited agricultural resource whose future availability is in question. Therefore, identification of alternative forms of P fertilizers is important. Poultry litter ash (PLA), a byproduct of bioenergy production, contains high concentrations of P comparable to conventional fertilizers. Forms of P contained in PLA have been characterized as having low water solubility. Nutrient losses during containerized plant production are high due to excessive inputs of water and nutrients and low nutrient sorption capacities of common horticultural substrate components. Environmental concerns over reduced water quality intensify this …

Suspensory Filaments, Santiago Pineda Jan 2013

Suspensory Filaments, Santiago Pineda

LSU Master's Theses

The interrelationships between vision, desire, and language are the elements that drive my artistic practice. “What is seeing?” “How is seeing related to desire?” These questions are at the base of my interests. I recognize optics as a subset of perception, yet I strive to reform them into interchangeable components. My interest in optics is based on doubt. I’m not interested in optic’s correctness, clinical orientation, or current sophistication, but rather in undermining its limitations. Our culture still struggles to absorb the notion of the sentient being, one example is our acuity of vision being standardized to 20/20. Within my …

Development Of Watershed-Based Modeling Approach To Pollution Source Identification, Yangbin Tong Jan 2013

Development Of Watershed-Based Modeling Approach To Pollution Source Identification, Yangbin Tong

LSU Master's Theses

Identification of unknown pollution sources is essential to environmental protection and emergency response. A review of recent publications in source identification revealed that there are very limited numbers of research in modeling methods for rivers. What’s more, the majority of these attempts were to find the source strength and release time, while only a few of them discussed how to identify source locations. Comparisons of these works indicated that a combination of biological, mathematical and geographical method could effectively identify unknown source area(s), which was a more practical trial in a watershed. This thesis presents a watershed-based modeling approach to …

Temporal Cycles, Sarah Anne Shearer Jan 2013

Temporal Cycles, Sarah Anne Shearer

LSU Master's Theses

Temporal Cycles explores how systems and changes in the human body parallel those in nature. The investigation takes the form of a print installation, which captures the essence of bodily processes. The serial nature of printmaking and the organic world plays an important role as biomorphic forms and hourglass shapes are repeated in numerous renditions that breathe, pulse, expand, wither, ovulate, and transform. Labyrinths of pattern, texture, and color connect the symbolic forms as the installation tracks the evolution of processes in the body, and the forms reveal themselves through their pictorial associations.
