Evidence Of Neotectonic Activity In Southwest Louisiana, Jordan Oliver Heltz Jan 2005

Evidence Of Neotectonic Activity In Southwest Louisiana, Jordan Oliver Heltz

LSU Master's Theses

A methodology that combines high-resolution topographic mapping, field observations, subsurface evaluation, and geodetic data analysis has successfully located several fault-related geomorphic steps in an area of southwestern Louisiana once thought to be relatively devoid of such features. Comparison of height differences of benchmarks straddling these suspected fault-related steps shows that vertical displacement rates on faults in the study area ranged from about 2 mm/yr to as much as 6 mm/yr during the 1960’s and 1970’s. However, leveling data obtained as recently as January 2005 reveals that the majority of these faults are currently moving at rates of less than 1 …

Molecular Dynamics Simulations Of Biological Membranes In The Presence Of Cryoprotectants, Dinesh Pinisetty

LSU Master's Theses

Cryopreservation is a process that is characterized by the transport of water and cryoprotectants through the cell membrane. This phenomenon has been studied in extensive detail at the macroscopic (µm) scale but in a somewhat more limited fashion at the microscopic (nm) scale. In this study we develop several lipid bilayer models to approximate a cell membrane (nm) and present the effect of several different cryoprotectants on the structural characteristics of these lipid bilayers using molecular dynamic simulations. The lipid bilayer models included dipalmitoylphosphatidylcholine (DPPC), dimyristoylphosphatidylcholine (DMPC) and palmitoyleylphosphatidylcholine (POPC) while the cryoprotectants included methanol and dimethylsulfoxide (DMSO). The molecular …

Defining Modernity: Mentality And Ideology Under The French Second Empire, Gavin Murray-Miller Jan 2005

Defining Modernity: Mentality And Ideology Under The French Second Empire, Gavin Murray-Miller

LSU Master's Theses

This study intends to examine the relationship between popular conceptions of modernity and Republican ideology during the Second Empire, 1852-1870. With the advent of the industrial revolution in France, scientific knowledge came to be equated with notions of progress and innovation, leading intellectual elites to design philosophical and social systems predicated upon the authority of scientific analysis and objectivity. Influenced by the intellectual currents under the Second Empire, a new generation of Republican political theorists incorporated notions of science into their ideological outlook, ultimately engendering a moderate brand of Republicanism which played a significant role in the founding of the …

The Influence Of Transdermally Administered Fentanyl On Isoflurane Requirements In Normothermic And Hypothermic Dogs, Diane Wilson Jan 2005

The Influence Of Transdermally Administered Fentanyl On Isoflurane Requirements In Normothermic And Hypothermic Dogs, Diane Wilson

LSU Master's Theses

Intraoperative reductions in serum fentanyl levels in dogs with induced moderate hypothermia and transdermal fentanyl patches (TDF) in place has been documented. The impact of such reductions has not been evaluated nor has the anesthetic sparing effect of the TDF. Reductions in serum levels may be the result of either a decreased uptake of fentanyl from the dermal depot, or a biophase shift. The objective of this investigation was to determine whether the minimum alveolar concentration (MAC) of isoflurane was altered in the presence of TDF in normothermic and hypothermic dogs. Six mature, healthy, mixed breed dogs were anesthetized on …

Comparative Analysis Of Conventional And Ici-Self-Cancellation Digital Video Broadcasting Transceivers, Khaled Z. Matarneh Jan 2005

Comparative Analysis Of Conventional And Ici-Self-Cancellation Digital Video Broadcasting Transceivers, Khaled Z. Matarneh

LSU Master's Theses

Digital video broadcasting–terrestrial (DVB-T) is one of the important technologies in the communication area because of its capability of high data-rate multimedia transmission. Orthogonal frequency division multiplexing (OFDM) has been the backbone technique in the current DVB-T systems adopted by Europe and Japan. However, since the OFDM system is very sensitive to the frequency synchronization and phase errors, which will induce the intercarrier interference (ICI), the ongoing research has been dedicated to this ICI problem in the presence of the Doppler frequency drift and the fading channels. A means to deal with the ICI problem is called the ICI self-cancellation …

A Crisis Of Opportunity: The Example Of New Orleans And Public Education In Antebellum Louisiana, Sarah Elisabeth Lipscomb Jan 2005

A Crisis Of Opportunity: The Example Of New Orleans And Public Education In Antebellum Louisiana, Sarah Elisabeth Lipscomb

LSU Master's Theses

The purpose of this study is to explore the development of public education in antebellum Louisiana. Using primarily public records, I found that despite the successful system instituted in New Orleans in the early 1840s, the rest of Louisiana faltered in its attempts to establish free public schools. Notwithstanding the requirement contained in the 1845 Constitution that each parish must organize public schools, the lack of guidance, supervision, and funding from the state legislature all coalesced to condemn public education in most of the rest of the state. As public schools in New Orleans thrived throughout the decades leading up …

Genetic Diversity Among Sugarcane Clones Using Target Region Amplification Polymorphism (Trap) Markers And Pedigree Relationships, Jie Alojado Arro Jan 2005

Genetic Diversity Among Sugarcane Clones Using Target Region Amplification Polymorphism (Trap) Markers And Pedigree Relationships, Jie Alojado Arro

LSU Master's Theses

Genetic diversity is indispensable to sustain genetic gain in breeding programs. Cultivated sugarcane is a highly heterozygous hybrid derived from crossing two highly heterozygous parents. Sugarcane breeders traditionally rely on pedigree records to select parents. Molecular markers now make it possible to assess genetic diversity at the DNA level. Sixty three sugarcane clones were characterised using Target Region Amplification Polymorphism (TRAP) markers and pedigree relationship (Coefficient of parentage (COP)). The TRAP is a PCR-based marker with a fixed primer designed from Expressed Sequence Tag (EST) sequences paired with an arbitrary primer. It is supposed to unravel trait based polymorphism in …

The King George Island Mounds Site (16lv22): A Late Archaic Mound Complex Along The Lower Amite River, Fiona Helena Vasbinder Jan 2005

The King George Island Mounds Site (16lv22): A Late Archaic Mound Complex Along The Lower Amite River, Fiona Helena Vasbinder

LSU Master's Theses

The King George Island Mounds site (16LV22) is one of four conical mound sites located along the lower Amite River in Livingston Parish, Louisiana. Gagliano originally reported the site in 1957 as containing two conical mounds. Initially, it was postulated that the Lower Amite River mounds might date to the Marksville period based on the similarities of shape. Recent research conducted at the site indicates that the site may contain up to five conical mounds that date to the Late Archaic period. Geomorphological, pedological, and archaeological data indicate an initial Archaic occupation. Archaic period artifacts were recovered from excavations above, …

Comorbidity Of Attention-Deficit/Hyperactivity Disorder And Posttraumatic Stress Disorder Among Low Income Urban Youth, Karen Ann Laslie Jan 2005

Comorbidity Of Attention-Deficit/Hyperactivity Disorder And Posttraumatic Stress Disorder Among Low Income Urban Youth, Karen Ann Laslie

LSU Master's Theses

Chronic exposure to violence is becoming increasingly common for urban children, placing them at an increased risk of developing psychopathology. For children exposed to chronic violence, two common diagnoses are Attention-Deficit/Hyperactivity Disorder (ADHD) and Posttraumatic Stress Disorder (PTSD). However, symptom overlap between these disorders has made differential diagnosis difficult. Most studies looking at the comorbidity between ADHD and PTSD have focused only on maltreated children. This study is the first to look at comorbid rates of ADHD and PTSD for children exposed to chronic violence, not limited to maltreatment. Specifically, this study evaluated rates of PTSD symptoms in children with …

Riding Out The Risks: An Ethnographic Study Of Risk Perceptions In A South Louisiana Bayou Community, Susan Camille Manning Jan 2005

Riding Out The Risks: An Ethnographic Study Of Risk Perceptions In A South Louisiana Bayou Community, Susan Camille Manning

LSU Master's Theses

This ethnographic study explores the risk perceptions of a small unincorporated coastal community in southeastern Louisiana. This community has experienced social and environmental change due to events including tropical storms and hurricanes, erosion, subsidence, oil and gas activities, development, and the impact of global seafood markets. Many global risk perception studies have focused on the perception of risk to human health and property connected with natural and technological disasters, but few have explored the issue of minorities and small at-risk communities. To explore this theoretical and methodological gap, this study uses a variety of qualitative ethnographic methods to examine a …

Associations Of Avian And Herpetofauna Communities With Forest Management At Multiple Spatial Scales, Holly Grace Legrand

LSU Master's Theses

Decline of amphibians, reptiles, and numerous Neotropical migrant birds has been attributed to habitat destruction and alteration, which warrants examination of these groups in managed forests and their association with habitat characteristics at multiple spatial scales. We surveyed avifauna and herpetofauna communities in 3 managed forests in Louisiana during 2003-2004. Study areas included Sherburne Wildlife Management Area (WMA), a bottomland hardwood forest under uneven-aged management, Ben’s Creek WMA, an even-aged, short-rotation loblolly pine plantation, and Sandy Hollow WMA, a longleaf pine-savannah maintained with prescribed fire. Field techniques included surveys consisting of avian point counts, drift fence arrays (PFFT), cover boards, …

Castle To Condo, Country To Corporation: What Becomes Of Hamlet In Almereyda's Modern World, Melissa Trosclair Daigle Jan 2005

Castle To Condo, Country To Corporation: What Becomes Of Hamlet In Almereyda's Modern World, Melissa Trosclair Daigle

LSU Master's Theses

This paper looks into the inner workings of Michael Almereyda's Hamlet (2000). Even though Almereyda updates the setting and cuts many of the lines, sometimes entire scenes, from the source text, he is able to convey the some of the themes through his use of technology and media. While some themes do transfer into the postmodern setting, the places of discord are most interesting. Of particular interest is his use of modern technologies to display the corruption found in Shakespeare's play. These technologies, including speakerphone, surveillance equipment, wiring devices, handheld camcorders, and still photography, create an atmosphere of both continual …

Molluscan Taphonomy As A Proxy For Recognizing Fossil Seagrass Beds, Jill Suzanne Leonard-Pingel Jan 2005

Molluscan Taphonomy As A Proxy For Recognizing Fossil Seagrass Beds, Jill Suzanne Leonard-Pingel

LSU Master's Theses

Seagrass beds, important marine ecosystems both economically and environmentally, have a poor fossil record. As a result, little is known about the geographic distribution of seagrasses over historic and geologic time, or their abundance when unaltered by anthropogenic effects. The purpose of this study is to define a taphonomic signature unique to seagrass beds that can be used as a proxy for identifying the seagrass habitat in the fossil record. In order to develop this proxy, sediment samples from Recent seagrass and non-seagrass environments were collected, and the molluscan bioclasts from these samples were categorically ranked for the following taphonomic …

Growth Of A Slash Pine Spacing Study Five Years After Thinning, Jamie Camille Schexnayder Jan 2005

Growth Of A Slash Pine Spacing Study Five Years After Thinning, Jamie Camille Schexnayder

LSU Master's Theses

In 1994, a 17 yr old, slash pine spacing study was thinned to 35% of the maximum stand density to evaluate the influence of prethinning stand conditions on postthinning growth after thinning to a common stand density. It was expected that plots thinned to a common growing stock level should have equal growth increments and if growth was not equal then the difference was related to prethinning stand conditions. Stand growth variables of quadratic mean diameter increment, stand-level basal area increment, and gross-volume increment were evaluated to determine the influence of initial spacing, stand density, and prethinning crown size before …

Women's Uses Of The Internet, Rachelle Powell Jan 2005

Women's Uses Of The Internet, Rachelle Powell

LSU Master's Theses

In this study I will look at the main reasons women use the Internet. Studies about women and the Internet are divided; some indicate less use of the Internet than men, but other studies show strong evidence of a narrowing gap in use. Due to this lack of clarity, a study that looks exclusively at women’s Internet activities and usage is needed. Although qualitative research does not test or apply theory the same way quantitative research does, uses and gratifications theory informed this study. This is an exploratory study of women and the Internet.
