Responses Of A Louisiana Oligohaline Marsh Plant Community To Nutrient Loading And Disturbance, Danielle Meert Dec 2008

Responses Of A Louisiana Oligohaline Marsh Plant Community To Nutrient Loading And Disturbance, Danielle Meert

LSU New Orleans Theses and Dissertations

Aboveground plant community dynamics in the oligohaline marsh at Big Branch Marsh National Wildlife Refuge, Louisiana, USA, were assessed in response to nutrient loading (3 N x 3 P treatments) and disturbance (both planned lethal disturbance and stochastic tropical storm/hurricane disturbance). Sampling was conducted seasonally from April 2004 to September 2006. Spartina patens and Schoenoplectus americanus are co-dominant plant species in this marsh. Low N-loading additions resulted in increased S. patens cover. However, increased N loading did not result in a shift in plant community composition despite S. americanus consistently having higher leaf tissue N than S. patens. Our results …

Comparative Hydrodynamic Testing Of Small Scale Models, Jared Acosta Dec 2008

Comparative Hydrodynamic Testing Of Small Scale Models, Jared Acosta

LSU New Orleans Theses and Dissertations

Early in the ship design process, naval architects must often evaluate and compare multiple hull forms for a specific set of requirements. Analytical tools are useful for quick comparisons, but they usually specialize in a specific hull type and are therefore not adequate for comparing dissimilar hull types. Scale model hydrodynamic testing is the traditional evaluation method, and is applicable to most hull forms. Scale model tests are usually performed on the largest model possible in order to achieve the most accurate performance predictions. However, such testing is very resource intensive, and is therefore not a cost effective method of …

Draumkvedet And The Medieval English Dream Vision: A Study Of Genre, Christian Carlsen Dec 2008

Draumkvedet And The Medieval English Dream Vision: A Study Of Genre, Christian Carlsen

LSU New Orleans Theses and Dissertations

The Medieval English dream vision evidence influences from a variety of earlier vision literature, notably the apocalyptic vision and narrative dream. Philosophical visions by Plato, Cicero and Boethius, and Christian revelations of John and Paul contain traits that found their way into the dream poems by Langland, the Pearl poet and Chaucer. The Norwegian ballad Draumkvedet exhibits features that mirror these English visions. Notable characteristics pertaining to the character of the dreamer, the interplay between dreamer and dream, imagery of the vision, and structure, point to a common set of generic influences. Comparing Draumkvedet with its English counterparts demonstrates that …

Glucose And Glucosamine Derivatives As Novel Low Molecular Weight Gelators, Sherwin Cheuk Dec 2008

Glucose And Glucosamine Derivatives As Novel Low Molecular Weight Gelators, Sherwin Cheuk

LSU New Orleans Theses and Dissertations

Low molecular weight gelators (LMWGs) are small molecules that are capable of entrapping solvents to form a gel in organic solvents or aqueous solution. These compounds rely solely on noncovalent forces to form the fibrous networks necessary to entrap a variety of solvents. The organogels and hydrogels thus formed could have applications in a variety of fields from environmental to biological to medicinal. Carbohydrates are ideal starting materials to synthesize LMWGs, because of their natural abundance, dense chirality, and biocompatibility. D-Glucose is the most common monosaccharide and D-glucosamine is isolated from natural sources, such as crab shells. Several series of …

Development Of A Borehole Log Signature For Oceanic Anoxic Events And Its Application To The Gulf Of Mexico, Asani Brewton Dec 2008

Development Of A Borehole Log Signature For Oceanic Anoxic Events And Its Application To The Gulf Of Mexico, Asani Brewton

LSU New Orleans Theses and Dissertations

Oceanic anoxic events (OAEs) are periods in Earth's history when oceans were depleted in dissolved oxygen and characterized by deposition of organic-rich sediments. The Oceanic Drilling Program (ODP) has drilled through OAEs in a number of areas worldwide, collecting core and borehole log data. This project attempts to identify a characteristic signature from known ODP OAE sections using these data and to apply the signature to identify OAE intervals in Gulf of Mexico wells where cores are lacking. Additionally, pseudo density curves were generated from ODP logs and compared to bulk density logs to determine if the deviation between the …

Response Of Barrier Island Fish Assemblages To Impacts From Multiple Hurricanes: Assessing Resilience Of Chandeleur Island Fish Assemblages To Hurricanes Ivan (2004) And Katrina (2005), Mark Chad Ellinwood

LSU New Orleans Theses and Dissertations

Hurricanes can temporarily disrupt seasonal patterns of fish assemblage change or result in permanent changes in fish assemblages. I studied the effects of two hurricanes on fish assemblages at the Chandeleur Islands and the possible influence that storm-generated tidal channels may have on the composition of local fish assemblages. I also compared recently collected data to historic ichthyofaunal survey data collected over thirty years ago at the Chandeleur Islands. Near shore fish assemblages changed the most after hurricanes but changes in species composition were primarily due to increases in abundance and diversity. During July 2007 there was no significant difference …

The Impact Of Growth Management Policies On Urban Form: Evidence From U.S. Metropolitan Areas With Growth Management Policies, Muhammed Islam

LSU New Orleans Theses and Dissertations

The contemporary urban development pattern in the United States is characterized by land consumptive nature of development, such as a sprawled development pattern. Out of concern that the social and environmental costs of this development pattern outweigh their benefits, cities, counties and states have created a wide range of policy instruments designed to manage urban growth and to protect open spaces from development. The present research deals with such strategies in three study areas namely Portland Metropolitan Area, OR; Montgomery County, MD; and Orange County, FL in order to find out if growth management strategies have been able to reduce …

Otherness And Assimilation: The Poetry Of Double-Consciousness In The Works Of Charles Simic, Marilyn Chin, And Susan Atefat-Peckham, Katherine Kidder

LSU New Orleans Theses and Dissertations

This paper examines assimilation and double-consciousness in the poetry of Charles Simic, Marilyn Chin, and Susan Atefat-Peckham. Each of these three poets writes in English in an American setting but has a different heritage. Simic is a native Yugoslavian (Serbia) who fled Europe during WWII. Chin arrived in the U.S. from Hong Kong as a child, and Atefat-Peckham is a first-generation American raised by Iranian parents. Each of these poets expresses some degree of assimilation and double-consciousness (as described by various theorists including W.E.B. Du Bois and Werner Sollors, among others) through the form and content of their poetry. This …

A Semi-Supervised Information Extraction Framework For Large Redundant Corpora, Eric Normand Dec 2008

A Semi-Supervised Information Extraction Framework For Large Redundant Corpora, Eric Normand

LSU New Orleans Theses and Dissertations

The vast majority of text freely available on the Internet is not available in a form that computers can understand. There have been numerous approaches to automatically extract information from human- readable sources. The most successful attempts rely on vast training sets of data. Others have succeeded in extracting restricted subsets of the available information. These approaches have limited use and require domain knowledge to be coded into the application. The current thesis proposes a novel framework for Information Extraction. From large sets of documents, the system develops statistical models of the data the user wishes to query which generally …

Salinity Transport In A Finite-Volume Sigma-Layer Three-Dimensional Model, Angel Gabriel Retana Dec 2008

Salinity Transport In A Finite-Volume Sigma-Layer Three-Dimensional Model, Angel Gabriel Retana

LSU New Orleans Theses and Dissertations

The objective of this study was to develop a 3-D model for The Pontchartrain Estuary that was capable of long-term mass conservative simulation of salinities. This was accomplished in a multi-stage approach involving: a physical model of salinity exchange through a pass; a 3-D FVCOM model of the physical experiment; the development and testing of an FVCOM model for an idealized Pontchartrain Basin; and for the entire estuary. The data from the physical model tests were used to validate the performance of the FVCOM model with density-driven flows. These results showed that hydrostatic FVCOM captured the primary internal wave movement. …

Cooperative Jamming In Wireless Networks - Turning Attacks Into Privacy Protection, Jingqi Wu Dec 2008

Cooperative Jamming In Wireless Networks - Turning Attacks Into Privacy Protection, Jingqi Wu

LSU New Orleans Theses and Dissertations

Generally, collisions between packets are undesired in wireless networks. We design this scheme, Cooperative Jamming in Wireless Networks (CJWN), to make use of collision to protect secret DATA packets from being sniffed by a nearby eavesdropper. We are intending to greatly increase the Packet Error Rate (PER) at the eavesdropper when the PER at the receiver is maintained at an acceptable level. This scheme is not intended to completely take the place of various encryption/decryption schemes which are working based on successfully received packets. Adding CJWN to the popular CSMA/CA adopted in IEEE 802.11 will add more security even the …

Preparation, Characterization, And Application Of Liposomes In The Study Of Lipid Oxidation Targeting Hydroxyl Radicals, Chanel Fortier Dec 2008

Preparation, Characterization, And Application Of Liposomes In The Study Of Lipid Oxidation Targeting Hydroxyl Radicals, Chanel Fortier

LSU New Orleans Theses and Dissertations

In the onset of many chronic illnesses including Parkinson’s, Alzheimer’s, and cardiovascular diseases, there is evidence to support the delicate balance between prooxidant and antioxidant species is shifted in favor of the former. Under these conditions, many reactive oxygen species (ROS) including hydroxyl radicals, are generated. Hydroxyl radicals formed in close proximity to DNA, nucleotides, proteins, and lipids rapidly oxidize these biological molecules in a nonspecific way. However, their toxicity is limited by their short lifetimes. Currently, the mechanism by which hydroxyl radicals are involved in the onset of many illnesses, particularly with regard to lipid peroxidation, has yielded some …

Application Of X-Ray Diffraction Methods And Molecular Mechanics Simulations To Structure Determination And Cotton Fiber Analysis, Zakhia Moore Dec 2008

Application Of X-Ray Diffraction Methods And Molecular Mechanics Simulations To Structure Determination And Cotton Fiber Analysis, Zakhia Moore

LSU New Orleans Theses and Dissertations

The results of three very different studies are presented. X-ray diffraction has been utilized for single-crystal structure determinations, fiber diffraction analyses, and in conjunction with molecular modeling of Cellulose IIII. Although each technique is different in its sampling, data acquisition, data treatment, and identification, the common denominator has been the use of x-rays. The single-crystal structure determination of ethylene glycol bis(tropane-3-carboxylate) is presented as an example of the use of modern single-crystal x-ray instrumentation including the use of coupled charged devices (CCDs) as detectors for accurate data collection and rapid elucidation of crystal structures. The structure determination of Cellulose IIII …

Casa Samba: Twenty-One Years Of Amerizilian Identity In New Orleans1, Lauren E. Lastrapes Dec 2008

Casa Samba: Twenty-One Years Of Amerizilian Identity In New Orleans1, Lauren E. Lastrapes

LSU New Orleans Theses and Dissertations

Samba drumming and dance traditions work in New Orleans in ways that they do not elsewhere. Casa Samba, a drumming and dance troupe in the tradition of the Brazilian escolas de samba, shows how it works. Integral to this analysis of Casa Samba are the ways in which the group's identity and the identities of its individual members are processual, mutable, and "unfinished, always being remade" (Gilroy 1993:xi). This thesis examines how Casa Samba has situated itself in the New Orleans music scene. This work seeks, through ethnographic interviews with long term members, to identify what makes Casa Samba attractive …

Essays In Corporate Governance: Issues And Evidence From Equity Carve-Outs, Andrew Mulindwa Kayanga Dec 2008

Essays In Corporate Governance: Issues And Evidence From Equity Carve-Outs, Andrew Mulindwa Kayanga

LSU New Orleans Theses and Dissertations

This dissertation consists of three essays examining the relation between corporate governance and firm performance. The theme of this study is that the widely documented long-term underperformance in equity carve-outs can be partly explained by weak corporate governance. The first essay presented in Chapter 2 explores the effect of shareholder-rights protection on the performance of a sample of firms that initiated a carve-out during the period 1983-2004. Using the Gompers, Ishii, and Metrick (2003) index and Bebchuk, Cohen, and Ferrell (2004) entrenchment index, as proxies for the quality of shareholder-rights protection, I provide evidence that firms with better shareholder rights …

Two Essays On Liquidity Essay I: Information Related Trading On Two Nearly Identical Options Essay Ii: The Importance Of The Liquidity Premium In The Presence Of Declining Transactions Cost, Wei-Xuan Li

LSU New Orleans Theses and Dissertations

In the first essay, I examine the impact of the introduction of exchange traded funds (ETFs) options on the information related trading of index options. Two option pairs, NASDAQ 100 index (NDX) and ETF (QQQ, currently QQQQ ) options, and Standard and Poor's 500 index (SPX) options and S & P Depository Receipts (SPY) options, are studied. I test the hypothesis, based on the theory of Chowdhry and Nanda (1991), and Admati and Pleiderer (1988), that the information component of spreads for index options should decline after ETF options were introduced. The method of George, Kaul and Nimalendran (1991) is …

Twenty-Four-Hour Woman, Mawiyah Bomani

LSU New Orleans Theses and Dissertations

"Sweet Black Pussy for Sale" sets the stage for this very feminine and colloquial laced collection of verse. Both figuratively and literally, the voices of a seldom-traveled African-American culture are depicted through these songs. In this thesis, I consider myself a GRIOT, sworn to tell nothing but the truth. These poems speak from places some might consider sacred and others quite sinful. These poems moan out the anthems of those unsung heroes and heroines from my family lineage. The voices of my long dead grandfather, grandmother, aunts and great uncle haunt poems such as "Blues," "Salvation," "A Memorial for Lawrence," …

The Capacity Of The Black Protestant Church To Provide Social Ministry In Post-Katrina New Orleans, Marshall Truehill Jr.

LSU New Orleans Theses and Dissertations

This research is an ethnography which investigates the effects of Hurricane Katrina upon the capacity of African American Protestant churches in New Orleans to provide spiritual and social ministry to the city's underprivileged. More than three years after Hurricane Katrina unleashed its fury upon the city, fifty per cent of the churches remain as the hurricane left them. Pre-Katrina, fifty per cent of the population lived at or below the poverty line and depended upon faith-based programs as part of their support network and ladder toward selfsufficiency. Because of the disaster, there was substantive loss of parishioners, financial resources, and …

Multiple Solutions On A Ball For A Generalized Lane Emden Equation, Abeer Khanfar Dec 2008

Multiple Solutions On A Ball For A Generalized Lane Emden Equation, Abeer Khanfar

LSU New Orleans Theses and Dissertations

In this work we study the Generalized Lane-Emden equation and the interplay between the exponents involved and their consequences on the existence and non existence of radial solutions on a unit ball in n dimensions. We extend the analysis to the phase plane for a clear understanding of the behavior of solutions and the relationship between their existence and the growth of nonlinear terms, where we investigate the critical exponent p and a sub-critical exponent, which we refer to as ^p. We discover a structural change of solutions due the existence of this sub-critical exponent which we relate to the …
