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

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

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 …

The aim of the study is for this investigation to contribute to the …

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 …

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. …

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

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 …

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 …

Bharti, Joachim Messing, Rod A. Wing, Phillip Sanmiguel, Jeffrey L. Bennetzen, Carol Soderlund

Department of Horticulture & Landscape Architecture Faculty Publications

Background

Many plant genomes are resistant to whole-genome assembly due to an abundance of repetitive sequence, leading to the development of gene-rich sequencing techniques. Two such techniques are hypomethylated partial restriction (HMPR) and methylation spanning linker libraries (MSLL). These libraries differ from other gene-rich datasets in having larger insert sizes, and the MSLL clones are designed to provide reads localized to "epigenetic boundaries" where methylation begins or ends.

Results

A large-scale study in maize generated 40,299 HMPR sequences and 80,723 MSLL sequences, including MSLL clones exceeding 100 kb. The paired end reads of MSLL and HMPR clones were shown to …

Bumbling Biddies And Drunken Pats: Anti-Irish Humor In Antebellum New Orleans, Ashley Barckett

LSU New Orleans Theses and Dissertations

The Irish in New Orleans have been a notoriously understudied group. With the third largest Irish population in the country by 1860, New Orleans is crucial when trying to understand the Irish immigrant experience. Viewing the Irish from the public perspective, this study explores the Daily Picayune, New Orleans' largest newspaper, from its inception in 1837 to 1857, to decipher the city's attitudes towards the Irish. Jokes in particular are explored, their function being multifaceted. First, jokes grouped Irish women into three types in an effort to maintain control of a large and unfamiliar group of white women who did …

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 …

Abrupt Climate Change And Storm Surge Impacts In Coastal Louisiana In 2050, Jay Ratcliff

LSU New Orleans Theses and Dissertations

The most critical hazards impacting the world today are the affects of climate change and global warming. Scientists have been studying the Earth's climate for centuries and have come to agreement that our climate is changing, and has changed, many times abruptly over the history of our planet. This research focuses on the impacts of global warming related to increased hurricane intensities and their surge responses along the coast of the State of Louisiana. Surge responses are quantified for storms that could potentially occur under present climate but 50 years into the future on a coast subjected to current erosion …

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 …

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 …

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 …

Storm Water Management Using A High Density Rainfall Network Along With Long Term Records, Siamak N. Mokhtarnejad

LSU New Orleans Theses and Dissertations

The United States Weather Bureau had published Technical Paper No. 40 (TP-40) in 1961 which provides a rainfall atlas for the United States. These rainfall frequencies have been used by engineers throughout the United States including Jefferson Parish, Louisiana. Rainfall from Audubon and the New Orleans International Airport rain gauge stations were used with the Log Pearson Method to provide rainfall frequency for Jefferson Parish, Louisiana. The results from the frequency rainfall that were developed for this research along with the current Jefferson Parish design storm rainfall were applied to a typical urban development to evaluate the extent of flooding.

Search For The Standard Model Higgs Boson In The Missing Energy And Acoplanar B-Jet Topology At √S = 1.96 Tev, V. M. Abazov, Kenneth A. Bloom, Gregory R. Snow, D0 Collaboration

Kenneth Bloom Publications

We report a search for the standard model Higgs boson in the missing energy and acoplanar b-jet topology, using an integrated luminosity of 0.93 fb^-1 recorded by the D0 detector at the Fermilab Tevatron pp Collider. The analysis includes signal contributions from pp → ZH → ννbb, as well as from WH production in which the charged lepton from the W boson decay is undetected. Neural networks are used to separate signal from background. In the absence of a signal, we set limits on σ (pp → VH) x B(H → bb) at the 95% …

Text Mining In Radiology Reports, Tianxia Gong, Chew Lim Tan, Tze-Yun Leong, Cheng Kiang Lee, Boon Chuan Pang, C. C. Tchoyoson Lim, Qi Tian, Suisheng Tang, Zhuo Zhang

Research Collection School Of Computing and Information Systems

Medical text mining has gained increasing interest in recent years. Radiology reports contain rich information describing radiologist's observations on the patient's medical conditions in the associated medical images. However as most reports are in free text format, the valuable information contained in those reports cannot be easily accessed and used, unless proper text mining has been applied. In this paper we propose a text mining system to extract and use the information in radiology reports. The system consists of three main modules: a medical finding extractor a report and image retriever and a text-assisted image feature extractor In evaluation, the …

Flexible Screw Design For Bone Implant Application, Seule Kabir

Theses and Dissertations

Disruption of the scapholunate ligament can result in significant immediate and long-term disability. Of the available current acute and subacute treatment strategies for this disorder, the use of a solid screw to stabilize the scapholunate relationship has been proposed. However, subsequent carpal bone loss is an inherent risk to this technique. The goal of this study was to design a flexible orthopedic screw that can be placed between the scaphoid and lunate to restore more normal biomechanics without the risk of osteolysis. Several ideas were generated during the course of the study to create a moveable section in a bone …

Globalization And National Information Policy In Nigeria, Augonus Nnamdi Uhegbu

Library Philosophy and Practice (e-journal)

The paper focuses on the need for a national information policy in Nigeria in the face of globalization. The paper is not anti-globalization, but believes that although globalization facilitates global access to information and its generating media, it also has the potential of exposing Nigerians to obscene information materials, and of dumping unwholesome, improperly packaged and substandard information resources in the country. The conceptual explanation of both globalization and information policy is discussed. Also discussed is Nigeria 's contemporary information environment, which this paper sees as highly risky, volatile and uncoordinated. The paper argues that with national information policy, globalization …
