Myths And Realities, Isoko Onodera Jan 2011

Myths And Realities, Isoko Onodera

LSU Master's Theses

My work explores the manifold personalities and roles of contemporary women, through depicting different female figures from western mythology. The mythic women in my paintings each have their own personalities, stories and roles to play, which are often conflicting in nature. By having my model act as a mythological character and by replacing the scenes from mythology with a contemporary setting, my paintings emphasize the universal and timeless essence of women. Each painting also utilizes the symbolic use of color to intensify the sensory experience of the viewer. The mythic figures I rendered are Proserpine, Venus, Psyche, Penelope, Artemis, and …

What Is The Importance Of Oil And Gas Platforms In The Community Structure And Diet Of Benthic And Demersal Communities In The Gulf Of Mexico?, Sara Terrebonne Daigle Jan 2011

What Is The Importance Of Oil And Gas Platforms In The Community Structure And Diet Of Benthic And Demersal Communities In The Gulf Of Mexico?, Sara Terrebonne Daigle

LSU Master's Theses

Reef-dependent and reef-associated communities found on oil and gas platforms in the Gulf of Mexico occur in high densities and are species rich. Platforms may impact nearby communities through the introduction of benthic primary producers and by altering biological and environmental factors that may create influential gradients associated with these structures. To quantify the presence and effective distance exerted by such gradients, reef-dependent and reef-associated communities were analyzed in two ways: (1) community patterns of abundance and diversity were compared near and far from platforms; and (2) a food-web tracer was used to indentify basal resources from platforms used by …

Population-Level Responses Of The Mummichog, Fundulus Heteroclitus, To Chronic Nutrient Enrichment In A New England Salt Marsh, Konner Chadwick Lockfield Jan 2011

Population-Level Responses Of The Mummichog, Fundulus Heteroclitus, To Chronic Nutrient Enrichment In A New England Salt Marsh, Konner Chadwick Lockfield

LSU Master's Theses

Mummichog (Fundulus heteroclitus) responses to chronic whole-ecosystem nutrient enrichment were examined near Plum Island Sound, Massachusetts. Dissolved fertilizer was released into replicate salt marsh creeks over 6 growing seasons to simulate agricultural run-off (bottom-up effects). Density, biomass, secondary production, growth rate, and condition factor were estimated in fertilized and reference creeks. Mummichog densities were also used to determine if mummichog growth or health varied with density. Over 7,600 mummichogs were marked and released into the treatment and control areas to measure responses. Over 900 mummichogs were recovered. Mummichog abundance was higher (p = 0.055) in nutrient-enriched creeks than reference creeks …

The Design Of A Computer System To Determine The Causes Of Edema Using Magnetic Resonance Spectroscopy, Carl Allen Fink Jan 2011

The Design Of A Computer System To Determine The Causes Of Edema Using Magnetic Resonance Spectroscopy, Carl Allen Fink

LSU Master's Theses

Diabetes is a growing problem in the U.S.A., closely linked to the current obesity epidemic. Two common complications of diabetes, osteomyelitis of the foot, and Charcot's joint, are impossible to differentiate via traditional Magnetic Resonance Imaging. The background of Magnetic Resonance Spectroscopy, which transforms the time-domain MRI signal into the frequency domain spectrum, is explored, and its use to aid in this differentiation is proposed. Artificial Neural Networks can be employed to evaluate the MRS data and to automate the process.

Resistant Starch In The Diet Of Rodents Promotes An Increase In Fermentation And A Reduction In Body Fat In An Animal Model Of Dietary Obesity, Jason Andrew Charrier

LSU Master's Theses

In previous studies, in has been observed that the addition of resistant starch (RS) in the diet of rodents, a non-digestible fermentable fiber, promotes increases in markers of fermentation and improvements in body weight and body fat analysis when incorporated into low to moderate fat diets. This study investigated whether the same beneficial effects observed with RS addition in these lower fat diets could be obtained in a high fat diet, and if the type of fatty acid consumed in the diet makes a difference in markers of fermentation and body fat. Sprague Dawley rats (n=96) were fed as weight …

A Molecular Genetic Study On The Tofl/Tofr Quorum-Sensing System Of Burkholderia Glumae: The Major Pathogen That Causes Bacterial Panicle Blight Of Rice, Ruoxi Chen

LSU Master's Theses

Burkholderia glumae is the major causal agent of an economically important rice disease, bacterial panicle blight (BPB). The known virulence factors of B. glumae share the TofI/TofR quorum sensing system as their regulator. tofI and tofR genes encode the N-acyl homoserine lactone (AHL) synthase for the B. glumae quorum sensing signals, N-octanoyl homoserine lactone (C8-HSL) and N-hexanoyl homoserine lactone (C6-HSL), and the receptor for AHL, respectively. To better understand the relationship between quorum sensing and known virulence factors (toxoflavin, flagella and lipase), as well as, putative virulence factors (i.e. extracellular polysaccharide), mutagenetic and phenotypic analyses were applied to this study. …

Educational Qualification And Racial Attitudes: Does Educational Qualification Really Matter?, Bonny Ghosh Jan 2011

Educational Qualification And Racial Attitudes: Does Educational Qualification Really Matter?, Bonny Ghosh

LSU Master's Theses

Most of the literature on social inequality reports that traditional old-fashioned, overt racism has been transformed into a modern symbolic form of covert racism in contemporary American society. Eduardo Bonilla-Silva asserts that “color-blind racism” is the dominant form of racism that persists in the post-Civil Rights period in the USA. A large body of research argues that education may not make too much of a difference in individuals’ racial attitudes. Studies also show that despite the fact that education is a crucial social institution, it cannot make the ills of intolerance and negative racial perceptions cease to exist. Given the …

Response Of Disturbance-Dependent Breeding Bird Communities To Two Site Preparations In Loblolly Pine Plantations, Falyn Leann Owens Jan 2011

Response Of Disturbance-Dependent Breeding Bird Communities To Two Site Preparations In Loblolly Pine Plantations, Falyn Leann Owens

LSU Master's Theses

Disturbance-dependent birds throughout the United States have recently experienced significant declines due to fire suppression and conversion of wilderness to human-dominated landscapes. In Louisiana, young loblolly pine plantations are an important source of early- successional habitat for these specialist birds. However, changes in management practices may affect forest stand suitability for bird communities that rely on them. Here I examined how changes in two site preparations, tree row spacing [14 ft (4.3 m) vs. 20 ft (6.1 m)] and arrangement of post-harvest woody debris (piled vs. scattered), impacted breeding, disturbance- dependent birds. During four summers in 2006-2010, observers conducted point …

Unveiled Pandemonium, Christina Marie Johnson Jan 2011

Unveiled Pandemonium, Christina Marie Johnson

LSU Master's Theses

Unveiled Pandemonium is a body of work that acknowledges my struggles, as a woman, with skewed self-perception and how frayed, decayed bits of self-love affect interaction with daily life: the public sphere versus the private. Using both large-scale graphite drawings and intimately sized, full-color digital narrative sequences, I portray movement, as a state of freedom, while capturing each character in a position of physical or emotional constraint. To increase the tension each figure interacts with another visually and in narrative; a war with the self begins. Within the engagement of internal and external tensions, each character’s body becomes a battlefield …

Seed Rain And Advance Regeneration In Secondary Succession In The Brazilian Amazon, Lindsay Michelle Wieland Jan 2011

Seed Rain And Advance Regeneration In Secondary Succession In The Brazilian Amazon, Lindsay Michelle Wieland

LSU Master's Theses

Forest regeneration on abandoned land in the Brazilian Amazon depends first and foremost on prior land-use history. Abandoned clearcuts become dominated by Cecropia trees, but contain a rich mix of other arboreal genera and succession proceeds rapidly to a diverse forest. In contrast, abandoned land that has been burned repeatedly for pastures becomes dominated almost completely by Vismia trees and remains in monogeneric stands gaining few new genera over the same time interval. I tested the hypothesis that areas with repeated burns would have more re-sprouts, particularly Vismia re-sprouts. I also predicted that in monogeneric Vismia stands, seed dispersal would …

Fate Of Mississippi River Diverted Nitrate On Vegetated And Non-Vegetated Coastal Marshes Of Breton Sound Estuary, Christine M. Vanzomeren Jan 2011

Fate Of Mississippi River Diverted Nitrate On Vegetated And Non-Vegetated Coastal Marshes Of Breton Sound Estuary, Christine M. Vanzomeren

LSU Master's Theses

The Caernarvon Diversion meters Mississippi River water into coastal marshes of Breton Sound. Elevated levels of nitrogen in river water have sparked concerns that nutrient loading may affect marsh resilience and belowground biomass, as evidence from several marsh fertilization studies. These concerns resulted from observation that fresh and brackish Breton Sound marshes suffered extensive damage from Hurricane Katrina. The goal of this study is to determine the fate of nitrate (the dominant inorganic nitrogen form in the Mississippi River) in Breton Sound Estuary marshes. We hypothesized that most nitrate would be removed by denitrification and that nitrate loading would not …

Changes In Select Phenolic Compounds During Ethanol Fermentation And Acetification Of Raspberry, Blueberry And Persimmon, Yen-Ping Tan

LSU Master's Theses

Polyphenols are major dietary components in fruits and vegetables. Many research and epidemiological studies have reported that phenolic compounds, such as anthocyanins, may have a protective effect against various degenerative diseases. Phenolics in grape wine have been extensively studied but information on changes of phenolics in wine and vinegar made from other fruit crops is limited, however. This research started with the objective of determining the effect of proteases in preventing phenolic and, specifically, anthocyanin degradation in the ethanolic fermentation of black raspberries to reduce sugar content. The results of this study led to investigations of changes of other polyphenols …

Effect Of Sediment Slurry Application On Selected Aspects Of Sulfur, Iron, And Manganese Biogeochemistry In A Coastal Louisiana Marsh, Martin Kyle Maxwell

LSU Master's Theses

Coastal wetlands, long recognized to be among the most productive ecosystems on the planet, are being lost at a disturbingly high rate in coastal Louisiana due to both eustatic sea-level rise and land subsidence. A number of approaches have been proposed for reducing wetland loss and restoring deteriorated wetlands, among which the addition of sediment to increase marsh surface elevation is promising. However, little is known about how the added sediment affects the biogeochemistry of marsh sediment. The objective of this study was to determine the effects of sediment slurry addition on sulfur, iron, and manganese biogeochemistry in a subsiding …

Development Of A Total Nutrient Treatment System For Alligator And Dairy Parlor Wastewater Using Hydrated Lime And Organic Bacterial Growth Media, Troy Francis Davis Jan 2011

Development Of A Total Nutrient Treatment System For Alligator And Dairy Parlor Wastewater Using Hydrated Lime And Organic Bacterial Growth Media, Troy Francis Davis

LSU Master's Theses

Over application of phosphorus and the loss of ammonia-nitrogen to runoff and volatilization have resulted in the buildup of phosphorus in agricultural top soils around the world, and especially in the United States. Over the past few decades, raising livestock has trended towards the development of the Confined Animal Feeding Operations (CAFO’s) which produce large volumes of wastes that need to be treated before being land applied. Nutrient treatment systems have typically focused on one nutrient singularly: either nitrogen or phosphorus. In order to develop a total nutrient system a phosphorus and nitrogen system had to be developed and evaluated …

Modeling Of First-Flush Reactor For Stormwater Treatment, Shaowei Sun Jan 2011

Modeling Of First-Flush Reactor For Stormwater Treatment, Shaowei Sun

LSU Master's Theses

Stormwater runoff is one of the most common sources of non-point source water pollution to lakes, rivers and estuaries. Nitrate-nitrogen in stormwater runoff is an important limiting factor to the eutrophication phenomenon. While most pollutants and nutrients, including nitrate-nitrogen, in stormwater are discharged into receiving waters during the first-flush period, no existing Best Management Practices (BMPs) are specifically designed to capture and treat the first-flush portion of urban stormwater runoff. In addition, nitrate-nitrogen removal rates of most existing BMPs are relatively low. This thesis presents results from both laboratory experiments and numerical modeling of nitrate-nitrogen removal in a designed first-flush …

Sensing Synesthesia, Jeffrey Harlan Johnson Jan 2011

Sensing Synesthesia, Jeffrey Harlan Johnson

LSU Master's Theses

Sensing Synesthesia is an exhibition of experiments, carried out through the medium of graphic design as an attempt to generate a synesthesiac experience by visualizing sound. Since many elements within the realms of sound and sight are relative, creating a genuine synesthesiac experience for a viewing audience proved challenging. To address this problem, I created visual elements that corresponded with personal convictions, emotions and proclamations and presented them in a way congruent to the sounds being heard. Through these experiments, I discovered the personal growth of myself: the sharpened skills as a graphic designer, initiated interest in hand-rendered type as …
