Effects Of Capping On Biodegradation Of Organic Contaminants In Sediments, Eun Ju Lee Jan 2007

Effects Of Capping On Biodegradation Of Organic Contaminants In Sediments, Eun Ju Lee

LSU Doctoral Dissertations

Sediment capping remains an effective remediation technique for contaminated sediments due to its capability to contain contaminants and provide a sound habitat for indigenous biota. This research investigated the effect of capping on biodegradation of organic contaminants in Anacostia River sediments using both experimental and modeling techniques. 14C–Phenanthrene mineralization was monitored under various redox conditions in Anacostia River sediments. Mineralization of 14C–phenanthrene was strongly linked to sulfate reduction, which was the more energetic process than any other anaerobic condition in Anacostia sediments. Sulfate is a more promising terminal electron acceptor for intrinsic degradation in Anacostia River and other PAH contaminated …

Cold Adaption Behaviors Of Vibrio Vulnificus And Vibio Parahaemolyticus In Oysters, Chiung-Ta Wu Jan 2007

Cold Adaption Behaviors Of Vibrio Vulnificus And Vibio Parahaemolyticus In Oysters, Chiung-Ta Wu

LSU Master's Theses

Vibrio vulnificus is an estuarine bacterium that can cause primary septicemia as well as other serious wound infections. Vibrio parahaemolyticus is a gram-negative, halophilic bacterium that may cause gastroenteritis, diarrhea, headache, vomiting, nausea, abdominal cramps and is the leading cause of gastroenteritis in United States. Consumption of raw oysters is believed to closely relate with infection with Vibrio vulnificus and Vibrio parahaemolyticus. All strains of V. parahaemolyticus produce tlh genes and the major virulence factors of V.parahaemolyticus are the tdh and trh genes. This study was conducted to determine if Vibrio vulnificus and Vibrio parahaemolyticus clinical and environmental strains display …

Wind Loads For Petrochemical Structures, Samuel Amoroso Jan 2007

Wind Loads For Petrochemical Structures, Samuel Amoroso

LSU Doctoral Dissertations

Techniques currently available to practicing engineers for estimating wind loads for petrochemical structures have little theoretical or experimental basis. This dissertation research is an effort to expand the understanding of wind effects on petrochemical and other, similar structures. Petrochemical structures introduce geometric scales into wind tunnel model simulations below what are common for enclosed structures. Wind tunnel experiments were performed to help determine whether this will introduce problems in achieving dynamic similarity between models and prototypes. The experiments did not reveal any clear indication that petrochemical structures cannot be modeled in wind tunnels at scales similar to those used for …

Detection Of The Bloodmeal Origin Of Mosquitoes Collected At Alligator Farms, And West Nile Virus Activity In Mosquitoes Collected From Alligator Farms, Sentinel Chicken Surveillance Sites, And Larval Habitats, Isik Unlu

LSU Doctoral Dissertations

A three year study was conducted to determine if testing mosquitoes collected in modified sentinel chicken boxes for West Nile Virus (WNV) or testing sentinel chickens for WNV antibody would detect WNV activity prior to reports of human cases in East Baton Rouge (EBR) Parish, Louisiana. In one year we also compared the effectiveness of CDC light traps, gravid traps, and sentinel chicken box traps for collecting WNV positive mosquitoes. In all three years, we detected WNV activity in mosquito collections from sentinel chicken box traps prior to the onset of human cases, while there were no seroconversions in the …

Writing The Circle: Judicially Convened Sentencing Circles And The Textual Organization Of Criminal Justice, Emma Cunliffe, Angela Cameron Jan 2007

Writing The Circle: Judicially Convened Sentencing Circles And The Textual Organization Of Criminal Justice, Emma Cunliffe, Angela Cameron

All Faculty Publications

Trial court judges who work in remote Northern Canadian Aboriginal communities use judicially convened sentencing circles to gather information and develop sentencing recommendations in some intimate violence cases. Proponents claim that judicially convened sentencing circles are a restorative justice practice that heals the offender, his community, and the survivor of the violence. Proponents also look to sentencing circles as a tool to find a just outcome that minimizes Aboriginal men's incarceration. We use a methodology developed by feminist sociologist Dorothy Smith to consider whether the institutional priorities being established and approved by courts in sentencing circle cases provide adequate protection …

Somatic Computationalism: Damasio's Clever Error, Christopher D. Pope Jan 2007

Somatic Computationalism: Damasio's Clever Error, Christopher D. Pope

LSU Master's Theses

Neuroscientist Antonio Damasio wrote a book entitled DESCARTES’ ERROR (1994) in order to address popular misconceptions about the mind, particularly those which relate to Cartesian philosophy. One of the author’s major goals for the book is to argue that emotion contributes to reason, that emotion is in fact necessary for rational thought to occur. In order to link emotion to reason, Damasio proposes a theory of mind which explains several mental functions in terms of neurological representations. Consciousness, reason, instinct and emotion all occur because the brain forms representations of the subject’s body and of the world in which the …

Leveraging Lean Process Improvement Methodology To Promote Economic And Environmental Sustainability: Obstacles And Opportunities, Jennifer Doman Jan 2007

Leveraging Lean Process Improvement Methodology To Promote Economic And Environmental Sustainability: Obstacles And Opportunities, Jennifer Doman

Theses

We are on the verge of a paradigm shift in the regulatory community in the United States. The EPA is slowly moving away from command and control to a more collaborative structure, and Lean process improvement is one of the primary catalysts of change. A significant percentage of American enterprises have some experience with Lean methods, and the EPA and others believe that Lean can be leveraged to promote environmental benefits while still delivering valuable business benefits, such as increased productivity and reduced costs. This research explores both the opportunities available for businesses today, and the current obstacles encountered when …

Anomaly-Based Botnet Detection For 10 Gb/S Networks, Jonathon Donaldson Jan 2007

Anomaly-Based Botnet Detection For 10 Gb/S Networks, Jonathon Donaldson

Theses

Current network data rates have made it increasingly difficult for cyber security specialists to protect the information stored on private systems. Greater throughput not only allows for higher productivity, but also creates a “larger” security hole that may allow numerous malicious applications (e.g. bots) to enter a private network. Software-based intrusion detection/prevention systems are not fast enough for the massive amounts of traffic found on 1 Gb/s and 10 Gb/s networks to be fully effective. Consequently, businesses accept more risk and are forced to make a conscious trade-off between threat and performance. A solution that can handle a much broader …

Assisting Small And Medium Enterprises Establish Procedures For Verification, Management Review And Continual Improvement Of Iso 14001, Parimala Anthony Jan 2007

Assisting Small And Medium Enterprises Establish Procedures For Verification, Management Review And Continual Improvement Of Iso 14001, Parimala Anthony

Theses

This study addresses the issue of reaching small and medium-sized enterprises (SMEs) with appropriate means to help them establish procedures for verification, management review and continual improvement in accordance to the ISO 14001 Environmental Management System (EMS) standard. The relative contribution of SMEs to the total industrial environmental impact is unknown, but it is likely to be considerable, given their contribution to total production and their dominance in sectors such as information technology, electronics, metals, printing, textiles etc. Therefore, the role of SMEs in protecting and improving the environment, through their production and marketing of environmental technologies (for energy efficiency, …

Light Pollution: A Case For Federal Regulation, Timothy Berthaume

Theses

The purpose of this thesis is to examine the body of evidence concerning light pollution and exposure to artificial light and determine if the scientific research warrants regulatory oversight in the United States. The first question that guided this effort was: Does improper artificial lighting and exposure to light-at-night constitute a risk to human health and safety? The follow up question being: Is light pollution a concern to ecological systems, and if so to what extent? A comprehensive literature review was conducted to ascertain the status of the research—if any—in these two areas and what the findings were. The overarching …

How To Rewrite Torah: The Case For Proto-Sectarian Ideology In The Reworked Pentateuch (4qrp), Roger S. Nam Jan 2007

How To Rewrite Torah: The Case For Proto-Sectarian Ideology In The Reworked Pentateuch (4qrp), Roger S. Nam

Faculty Publications - Portland Seminary

This study challenges the initial categorization of the Reworked Pentateuch (4Q364-4Q367) as another non-sectarian textual witness to the Torah. A close analysis of the manuscripts suggests that certain unaligned readings likely ret1ect some of the sectarian ideas of the community. Other variants evoke both content and ideology of the authoritative "Rewritten Bible" documents, the Temple Scroll and Jubilees. These characteristics imply that 4QRP contains deliberate reworking of biblical material that is in line with sectarian ideology, in contrast to a mere mechanical copying of the text. Though the scroll may not be strictly sectarian, at the very least, it is …

Locally Conservative Fluxes For The Continuous Galerkin Method, Bernardo Cockburn, Jay Gopalakrishnan, Haiying Wang Jan 2007

Locally Conservative Fluxes For The Continuous Galerkin Method, Bernardo Cockburn, Jay Gopalakrishnan, Haiying Wang

Mathematics and Statistics Faculty Publications and Presentations

The standard continuous Galerkin (CG) finite element method for second order elliptic problems suffers from its inability to provide conservative flux approximations, a much needed quantity in many applications. We show how to overcome this shortcoming by using a two step postprocessing. The first step is the computation of a numerical flux trace defined on element inter- faces and is motivated by the structure of the numerical traces of discontinuous Galerkin methods. This computation is non-local in that it requires the solution of a symmetric positive definite system, but the system is well conditioned independently of mesh size, so it …

Representing The Object Of Controversy: The Case Of The Molecular Clock, Michael Dietrich Jan 2007

Representing The Object Of Controversy: The Case Of The Molecular Clock, Michael Dietrich

Dartmouth Scholarship

Through a case study of the controversies surrounding the molecular clock, this paper examines the role of visual representation in the dynamics of scientific controversies. Representations of the molecular clock themselves became objects of controversy and so were not a means for closure. Instead visual representations of the molecular clock became tools for the further articulation of an ongoing controversy.
