An Online Fabric Database To Link Fabric Drape And End-Use Properties, Ayse Gider Jan 2004

An Online Fabric Database To Link Fabric Drape And End-Use Properties, Ayse Gider

LSU Master's Theses

The main obstacle for adaptation of fabric selection through the Internet is that there is no objective selection method that is suitable for fashion fabrics. The purpose of this research is to develop an objective evaluation method for selecting fabrics through an online fabric database. The relationship between fabric mechanical properties and fabric drape was investigated. One hundred eighty-five commercial fabrics from different manufacturers were tested using the Kawabata fabric evaluation system (KES-FB) and Cusick drape tester. Applying regression analysis, the parameters that were significantly correlated with drape coefficient (DC) were determined. The test results, fabric structural parameters, and contact …

An Examination Of The Relationship Between Environmental Science And Law Due To Emerging Micro-Scale Gas Chromatography Technology, Alfred Ruks Politzer Jan 2004

An Examination Of The Relationship Between Environmental Science And Law Due To Emerging Micro-Scale Gas Chromatography Technology, Alfred Ruks Politzer

LSU Master's Theses

The intersection of science and law is very complex. The two disciplines frequently interact due to environmental issues. Expert testimony is most often the method used to introduce scientific data into the legal system. Advances in technology have allowed scientists to increase the preciseness and reliability of data produced. The development of the gas chromatograph and the recent microFAST gas chromatograph has greatly increased the amounts of data available to the legal system. The legal system has relatively recently developed a set of guidelines with which to evaluate scientific evidence and determine whether it should be admitted into trial. Previously …

Regional-Scale Eutrophication Models: A Bayesian Treed Model Approach, Angelina Freeman Jan 2004

Regional-Scale Eutrophication Models: A Bayesian Treed Model Approach, Angelina Freeman

LSU Master's Theses

Utilizing Bayesian hierarchical techniques, regional-scale eutrophication models were developed for use in the Total Maximum Daily Load (TMDL) process. The Bayesian tree-based (BTREED) approach allows association of multiple environmental stressors with biological responses, and quantification of uncertainty sources in the water quality model. Simple parametric models are often inadequate for describing complex datasets; the BTREED approach partitions the dataset, and describes the localized subsets of data with linear models, thereby providing a comprehensive representation of stressor and response interactions. Nutrient criteria data for lakes, ponds and reservoirs across the United States were obtained from the Environmental Protection Agency (U.S. EPA) …

The National D-Day Museum As Mystory Praxis, David A. Pye Jan 2004

The National D-Day Museum As Mystory Praxis, David A. Pye

LSU Master's Theses

Museums in general are shrines of collected memory and cultural values. The National D-Day Museum, in particular, presents the memory of World War II as a good and just action taken by the Allied forces against the evil of the Axis powers. In contrast with later wars, which might be seen as morally ambiguous or futile, World War II was and is thought of as "the good war." In this study, I explore and express how The National D-Day Museum encourages exploration and expression on the part of the visitor, using Gregory Ulmer’s concept and practice of mystory to analyze …

Estimating Impervious Surfaces From A Small Urban Watershed In Baton Rouge, Louisiana, Using Landsat Thematic Mapper Imagery, Kurt Johnson Jan 2004

Estimating Impervious Surfaces From A Small Urban Watershed In Baton Rouge, Louisiana, Using Landsat Thematic Mapper Imagery, Kurt Johnson

LSU Master's Theses

Many urban areas are using estimations of impervious surfaces as a means for better environmental management. This is because research over the last two decades indicate a consistent, inverse relationship between the percentage of impervious surfaces in a watershed and the environmental problems urban areas are experiencing. Although various methods for estimating impervious surfaces can be identified, few result in accurate and defensible estimations by which environmental problems can be assessed. This is especially important to rapidly expanding urban areas such as Baton Rouge, Louisiana where detailed records and planimetric data are lacking. Numerous studies have shown a potential for …

Excavations At The Bayou Grande Cheniere Mounds (16pl159): A Coles Creek Period Mound Complex, Timothy M. Schilling Jan 2004

Excavations At The Bayou Grande Cheniere Mounds (16pl159): A Coles Creek Period Mound Complex, Timothy M. Schilling

LSU Master's Theses

The Bayou Grande Cheniere Mounds are a large Coles Creek mound group in Plaquemines Parish, Louisiana. Excavations in January 2003 returned materials that allowed the site to be dated. Further analysis also suggests how these materials were used at the mounds. A settlement pattern study was undertaken and the results indicate that the social organization of coastal Coles Creek culture was sharply different than Coles Creek culture in the Lower Mississippi Valley. When viewed together, the material analysis and settlement analysis illustrates the processes and people that built the Bayou Grande Cheniere mounds.

Enhanced Flushing With Cyclodextrin For The Remediation Of Creosote Contaminated Soil, Monalisa Dutta Jan 2004

Enhanced Flushing With Cyclodextrin For The Remediation Of Creosote Contaminated Soil, Monalisa Dutta

LSU Master's Theses

Past practices of applying creosote and coal tar preservatives to wood, such as unlined pits and trenches, have resulted in contamination of the surface and ground water at thousand of sites. The low aqueous solubility, volatility and bioavailability of many these constituents limit their degradation by natural attenuation and standard remediation techniques such as ground water flushing, soil vapor extraction, and bioremediation. While research has shown that cyclodextrin solutions have the ability to enhance the solubility of some of the components of creosote, additional work is needed to evaluate its potential as a remedial agent for these sites. Equilibrium batch …

The Orthographic Characters (In No Particular Order), Alison Christina Frank Jan 2004

The Orthographic Characters (In No Particular Order), Alison Christina Frank

LSU Master's Theses

My work focuses on the development of playful and absurd combinations of small creatures that co-exist in a state of odd logic. The creatures share a vulnerable, somewhat fragile, quality, yet are assigned vital force in their existence. This juxtaposition is metaphorical for certain aspects of human existence. The Orthographic Characters is the title of a series of prints and paintings I have created that form a non-linear narrative. Each piece is inspired by the alliteration of one alphabet character. The writings form a bizarre, feverish context for the characters.

German Stereotypes In British Magazines Prior To World War I, William F. Bertolette Jan 2004

German Stereotypes In British Magazines Prior To World War I, William F. Bertolette

LSU Master's Theses

The British image of Germany as England's "poor relation," a backward cluster of feudal states, gave way during the nineteenth century to the stereotype of England's archenemy and imperial rival. This shift from innocuous Old Germany to menacing New Germany accelerated after German unification in 1871 as German economic growth and imperial ambitions became topics for commentary in British journals. But the stereotypical "German Michael," or rustic simpleton, and other images of self-effacing servile, loyal, honest and passive Old Germany lingered on into the late nineteenth century as a "straw man" for alarmist Germanophobes to dispel with new counter-stereotypes. These …

A Historical Approach To Training The Vocal Registers: Can Ancient Practice Foster Contemporary Results?, Taylor Lee Ferranti Jan 2004

A Historical Approach To Training The Vocal Registers: Can Ancient Practice Foster Contemporary Results?, Taylor Lee Ferranti

LSU Doctoral Dissertations

A review of the extant vocal literature containing the writings of Tosi, Mancini, and Garcí­a, shows that the topic of vocal registration appeared to be at the core of their training procedures. The essence of their vocal instruction centered around how the registers coordinated, separated, and developed to form the functional basis of a sound technique. However, of all the topics that encompass historical pedagogy, none will confound the diligent voice teacher more than the topic of vocal registers. For this reason, contemporary pedagogy has developed certain methodologies that appear to be at odds with the historical approach to training …

The Spectral Conforming Model And Its Applications, Jaeho Shim Jan 2004

The Spectral Conforming Model And Its Applications, Jaeho Shim

LSU Doctoral Dissertations

It has been observed that finite element or finite difference model of order can approximate with fair accuracy less than one-third of the eigenvalues of the underlying continuous system corresponding to the low spectrum. The new discrete model, namely the spectral conforming model, is developed to predict the eigenvalues of continuous systems in both the low and high spectra. The spectral conforming models are developed using an inverse vibration method. The classical vibration problem is the direct method. In the direct approach, the characteristic behaviors of the system, i.e. frequency response, natural frequency, and steady state response are analyzed and …

Durability Of Pine Strandboard Modified With Low Molecular Weight Phenol Formaldehyde, Matthew Daniel Voitier Jan 2004

Durability Of Pine Strandboard Modified With Low Molecular Weight Phenol Formaldehyde, Matthew Daniel Voitier

LSU Master's Theses

A continuing challenge for wood and wood-based composite building materials has been durability--the power of resisting agents or influences which tend to cause changes, decay, or dissolution; lastingness. In the case of wood-based products, this often requires a resistance to biological degradation and moisture related dimensional instability (particularly in particle and flake or strand boards). Borden Chemical Company has developed a new low molecular weight phenol formaldehyde additive, PD-112, to improve durability in composite wood products. This study investigated PD-112’s contribution to durability in oriented strand board (OSB) through laboratory testing of treated southern pine strandboard panels versus untreated control …

Difference In Sleep Disturbances Among Severely And Profoundly Retarded Adults With High Risk Behaviors, Carrie Jo Malone

LSU Master's Theses

Individuals with intellectual disabilities have been linked to higher incidences of a variety of mental illnesses when compared to the general population (Rutter, Tizard, Yule, Graham, & Whitmore, 1976; and Borthwick-Duffy, 1994). Because of the symptoms associated with mental retardation; such as limited social skills, delayed or minimal communication skills, and maladaptive behaviors, mental illness can be difficult to assess when combined with an intellectual disability (Sovner, 1986). Currently there is no available mechanism for diagnosing sleep disorders in adults with severe and profound mental retardation. The purpose of the first study is to provide validation of the Diagnostic Assessment …
