Damage Mechanics Of Composite Materials Using Fabric Tensors, Ziad N. Taqieddin
Damage Mechanics Of Composite Materials Using Fabric Tensors, Ziad N. Taqieddin
LSU Master's Theses
The major objective of this work is to relate continuum damage mechanics introduced through the concept of fabric tensors to composite materials within the framework of classical elasticity theory. A model of directional data-damage mechanics for composite materials is formulated using fabric tensors. In addition, a general hypothesis for damage mechanics is postulated. It is seen that the two available hypotheses of elastic strain equivalence and elastic energy equivalence may be obtained as special cases of the postulated general hypothesis. This general hypothesis is then used to derive the sought relationship between the damage tensor for composite materials and the …

The Economics Of Neutrality: Switzerland And The United States In World War Ii, Matthew Schandler
The Economics Of Neutrality: Switzerland And The United States In World War Ii, Matthew Schandler
LSU Master's Theses
The following study addresses the contentious issue of Swiss economic policy during the Second World War. In particular, it concentrates on the deterioration of Swiss-American relations that resulted from Switzerland’s economic ties to Nazi Germany. It is argued that Switzerland’s survival as a neutral and democratic country depended less on the defense preparations of the Swiss Army and more on the difficult trade negotiations with both the Axis and Allies. Varied sources that include American and Swiss governmental reports, diplomatic documents, and contemporary accounts of the war, support the argument that although moral considerations played a secondary role to economic …

Experimental And Numerical Study Of Feeding Channel In Proton Exchange Membrane Fuel Cell, Abul Bashar Mahmud Hasan
LSU Master's Theses
The performance of a Proton Exchange Membrane Fuel Cell (PEMFC) using different feeding configurations has been studied, with a focus on the water flooding due to electrochemical reaction. Feeding channel or Bipolar plate in Proton Exchange Fuel Cell is a dominating part. As feeding channel keeps direct contact with the gas diffusion layer, it helps efficiently supplying fuel and air into the gas diffusion layer for efficient production of electricity. Experimental data have been taken at hydrogen flow rates of 20,40,60,80,100 sccm for various bipolar plate arrangements. Three bipolar plates, namely serpentine, straight channel and interdigitated designs, were arranged in …
Development Of Non-Dairy Frozen Dessert Containing Soy Protein And Coconut Milk, Luciana Soler
Development Of Non-Dairy Frozen Dessert Containing Soy Protein And Coconut Milk, Luciana Soler
LSU Master's Theses
As consumers have pursued healthier lifestyles in recent years, consumption of soy foods has risen steadily, encouraged by scientific studies showing health benefits from these products. There is a large market for ice cream in the United States. However, since ice cream contains dairy ingredients, a number of Americans are not able to consume it because of dietary habits due to religious beliefs, lactose intolerance, vegetarianism or other related ideologies. For years, these groups of consumers have been able to substitute ice cream with frozen desserts containing soy protein as a substitute for milk protein, but never in the United …

The Effect Of Diets Varying In Dietary Cation-Anion Difference Fed In Late Gestation And In Lactation On Sow Productivity, Melanie Lynn Roux
LSU Master's Theses
Eighty-six primiparous or multiparous sows and their pigs were used to evaluate the effects of changing dietary cation-anion difference (DCAD) in late gestation and in lactation on sow productivity. Twenty sows were used in Exp. 1, and the dietary treatments consisted of a positive control (PC) corn-soybean meal (C-SBM) diet with four levels of DCAD (140, 99, 75, and 45 mEq/kg). These DCAD’s were achieved by four levels of SoyChlor (SC) additive (0, 1.5, 2.5, and 3.5%). In Exp. 2, 66 sows were used and the dietary treatments consisted of the diets providing DCAD of 140 and 45 mEq/kg. The …

LSU Master's Theses
In the summer of 2003 I conducted an archaeological study at Pork and Doughboy Point, Belize, under the direction of Dr. Heather McKillop. The site, situated amidst other ancient Maya coastal settlements of the Port Honduras in southern Belize, has only been tested for offshore deposits in the three decades since it was reported. The current research involved the first reported terrestrial excavations at the site. The goals of this investigation were to recover pottery that could be used to date the ancient Maya occupation and obtain artifacts that would suggest the nature of the site. From artifact analyses I …

Adventures Of A Former Girlfriend: A Novel, Colleen Helen Fava
LSU Master's Theses
This is a novel about a young woman trying to redefine herself after years of defining herself through her relationships with other people, most specifically her boyfriends, but also her family. The heroine faces many challenges: the end of a long-term relationship, the illness of her niece, complications with her best friends, and a revelation about her parent's relationship. These ordinary obstacles of everyday living will propel the main character into a confrontation with her perception of herself and the world around her.
Experimental Sloshing Studies In Sway And Heave Base Excited Square Tanks, Wei Peng
Experimental Sloshing Studies In Sway And Heave Base Excited Square Tanks, Wei Peng
LSU Master's Theses
In this thesis, free-surface water waves are experimentally investigated with a focus on sloshing in tanks. The sloshing problem is selected for its relatively simple geometry, yet it captures the features of nonlinearities including wave breaking. Free-surface motions are monitored in a square tank with base dimensions of 1 x 1 m2. Sloshing motions have been studied both off- and at resonance in shallow to deep water to investigate nonlinear free surface effects. The tank has been prescribed to move in sway and / or heave excitation. Interesting hysteresis behavior at the surface is captured at and near resonance. Faraday …
Spatial Heterogeneity In Forested Landscapes: An Examination Of Forest Fragmentation And Suburban Sprawl In The Florida Parishes Of Louisiana, Brady Randall Couvillion
Spatial Heterogeneity In Forested Landscapes: An Examination Of Forest Fragmentation And Suburban Sprawl In The Florida Parishes Of Louisiana, Brady Randall Couvillion
LSU Master's Theses
Forest fragmentation refers to the spatial distribution of forests in a landscape. Forest fragmentation drastically alters forest composition, habitat quality, genetic flow and many other ecological processes associated with forested ecosystems. This research examined spatial patterns and rates of forest fragmentation during the 1991-2001 period for a region in southeast Louisiana known as the "Florida Parishes." Following classification of 1991 and 2001 Landsat data into forest and non-forest classes, spatial patterns were examined using Fragstats 3.3 spatial analysis software. Spatial statistics such as patch density, perimeter to area ratios, core area indices, edge density, and various landscape continuity indices were …
Vinegar Fermentation, San Chiang Tan
Vinegar Fermentation, San Chiang Tan
LSU Master's Theses
Traditionally, the manufacture of vinegar provided a means of utilizing a large proportion of the cull fruit from apple-packing establishments and the waste from apple processing facilities. Most vinegar is now produced from distilled grain alcohol. Vinegar may be defined as a condiment made from various sugary and starchy materials by alcoholic and subsequent acetic fermentation. The vinegar bacteria, also called acetic acid bacteria, are members of the genus Acetobacter and characterized by their ability to convert ethyl alcohol (C2H5OH) into acetic acid (CH3CO2H) by oxidation. Vinegar can be produced from various raw materials like distilled alcohol, wine, rice wine …
Long-Term Changes And Variability In Northern Hemisphere Circumpolar Vortex, Kalyn Mackenzie Wrona
Long-Term Changes And Variability In Northern Hemisphere Circumpolar Vortex, Kalyn Mackenzie Wrona
LSU Master's Theses
Variability in the hemispheric-scale atmospheric circulation can be directly linked to variations in surface environmental features, such as temperature, precipitation, and pollutant transport. One indicator of the behavior of the hemispheric-scale circulation is the circumpolar vortex (CPV). This research utilizes a geographic information system (GIS) approach to determine the variability in the northern hemisphere (NH) CPV. Specifically, the area, shape, and centroid of the December, January, February, April, July, and October NHCPV are analyzed for 1959 – 2001 because these features may provide insight about relationships between hemispheric-scale circulation and global temperature change throughout the year. A “circularity ratio” is …

Clinical evidence supports the use for exogenous glutamine in the maintenance of muscle mass and immune system function in critically ill patients. Relatively little research has examined the benefits of glutamine for athletes engaged in heavy exercise training, despite a possible link between overtraining and glutamine. PURPOSE: To examine the influence of Glutamine on time to exhaustion and power after a prolonged bout of exercise. METHODS: Twelve men (Age: 19 to 30y) involved in cycle training were asked to participate in the study. All participants performed a Symptom-Limited Graded Exercise Test (SL-GXT) using the Astrand Cycle protocol. On a subsequent …
Thermal Management Of The Lsu Micro Gas Chromatograph, Praveen K. Pasupuleti
Thermal Management Of The Lsu Micro Gas Chromatograph, Praveen K. Pasupuleti
LSU Master's Theses
Gas chromatography is a technique widely used for the separation and analysis of gas samples. Gas chromatographs are used for environmental maintenance, monitoring sophisticated biological analyses, and to separate components from a mixture of gases for mass spectrometer analysis. There has been a tremendous interest in miniaturization of gas chromatograph systems because of the potential for portability, faster response time, lower dead volume, lower power consumption, and lower cost of operation. Conventional gas chromatography keeps the column at a constant temperature during separation, which is called isothermal analysis. Temperature programming is a mode of gas chromatography in which the column …
Stability Of Stochastic Pricing Models Under Volatility Fluctuations, Krassimir Zhivkov Nikolov
Stability Of Stochastic Pricing Models Under Volatility Fluctuations, Krassimir Zhivkov Nikolov
LSU Master's Theses
The standard theory of the stochastic models used to value financial derivatives contracts involves models whose input parameters are deterministic functions and often constants. Because of the random nature of the changes in the market prices of the financial instruments, the coefficients of these models are inevitably susceptible to random perturbation from their initial estimates. In this paper we will investigate the behavior of some of the most widely used models when small changes are applied to their volatility component. Starting with the Black-Scholes model for the price of a European call option, we will continue our analysis of the …
Influences On The Establishment Of County Wildfire Risk Mitigation: The Case Of California's Fire Safe Councils, Timothy Richard Soileau
Influences On The Establishment Of County Wildfire Risk Mitigation: The Case Of California's Fire Safe Councils, Timothy Richard Soileau
LSU Master's Theses
In response to increased annual wildfire destruction and insufficient wildfire mitigation approaches from the federal government, the state of California adopted Public Resources Code Sections 4290 and 4291 in the year 1991. These laws force the removal of fire-causing agents from public and private areas, and establish what is known as defensible space. Defensible space is defined in Section 4291 as the area within the perimeter of a parcel, development, neighborhood, or community where basic wildland fire protection practices and measures are implemented, providing the key point of defense from an approaching wildfire or escaping structure fire. One method to …
Persona, Joanna Norcross Coke
Persona, Joanna Norcross Coke
LSU Master's Theses
The narrative oil paintings in this show illustrate one or two female characters set in domestic interior spaces. The scenes bring with them allusions to suggest that something unusual has just happened or is about to happen by heightening the psychological emotional moments. The subject matter is intimate and painted on small supports to reinforce these feelings. The images go beyond the observed visual aesthetic or representation by shifting the picture plane and using dramatic color palettes and lighting to create deeper interior spaces, adding to the tension.
Urban Yellow Fever Diffusion Patterns And The Role Of Micro-Environmental Factors In Disease Dissemination: A Temporal-Spatial Analysis Of The Memphis Epidemic Of 1878, William Brennan Arden
Urban Yellow Fever Diffusion Patterns And The Role Of Micro-Environmental Factors In Disease Dissemination: A Temporal-Spatial Analysis Of The Memphis Epidemic Of 1878, William Brennan Arden
LSU Master's Theses
Most investigations that examine diffusion of disease through urban areas give relatively scant attention to the 'micro-environment.' Employing the many methods of macro-environmental analysis, most studies do not attempt to identify street-level or even residence-level temporal-spatial patterns of disease diffusion. As a result, the mechanisms that lead to diffusion on such small scales are left relatively undefined. There is no doubt that cumulatively these small-scale mechanisms contribute to the diffusion of disease over the urban environment. However, the level of contribution and the specific details of their dynamics remain unclear. This thesis investigated some of these unexplored areas by presenting …
Reduced Tillage And Residue Management Programs In Sugarcane (Saccharum Spp. Hybrids), Wilson Elie Judice
Reduced Tillage And Residue Management Programs In Sugarcane (Saccharum Spp. Hybrids), Wilson Elie Judice
LSU Master's Theses
The effect of tillage and weed control programs on ‘LCP 85-384’ sugarcane (Saccharum spp. hybrids) growth and yield and on economics was evaluated over two growing seasons. When row shoulders and middles were not tilled in March soil temperature in the non-cultivated sugarcane drill early in the growing season was equal to that where March tillage was performed. Sugarcane and sugar yield were each equivalent for the full season tillage (off-bar tillage in March plus layby tillage in May) and the no-till program. Weeds were effectively controlled with a March application of hexazinone at 0.59 kg ai/ha plus diuron at …
Changing Face: The Evolution Of Chinese Women's Dress And Appearance, Xiaolan Wang
Changing Face: The Evolution Of Chinese Women's Dress And Appearance, Xiaolan Wang
LSU Master's Theses
Women’s dress and appearance can reflect a lot about a civilized society. It is influenced by many factors as well. The dress and appearance of contemporary Chinese women have not been studied much by mass communication researchers. This paper, however, explored the factors that influence the development and evolution of contemporary Chinese women’s dress and appearance. It traced back from Dynastic China to Republican China and then to Mao’s red China to examine the historical and political influences imposed on the dress and appearance of Chinese women. Then, it used in-depth interviews to find out factors that influence women’s dress …
Full Circle, Elizabeth Cowhig
Full Circle, Elizabeth Cowhig
LSU Master's Theses
My paintings are a result of a mainly intuitive process that evolves out of the combination of shape, color, and texture and originates from personal ideologies involving health phobias and religious beliefs. The imagery in the paintings is of biological origin, cells that fill up with matter, dense spheres that recall cancerous build up, the compositions and colors are inspired by Italian Renaissance paintings. The tangible is inserted into the realm of the ethereal.

Evaluation Of Helicobacter Hepaticus Bacterial Shedding In Fostered And Strategically Housed C57bl/6 Mice, J. Robin Crisler Roberts
LSU Master's Theses
The murine pathogen Helicobacter hepaticus has important confounding effects on research. Neonatal fostering has been studied in our laboratory for elimination of infection in mice. The purpose of our study was to examine fostering of pups from experimentally infected dams in male-absent parturition, and to determine the significance of gender and time on quantity of bacterial colonization in the cecum and feces of C57BL/6 mice. Approximately 20 C57BL/6 mice were fostered per day from one to four days of age. None of the C57BL/6 pups tested positive by PCR in fecal or cecal samples through four days of age. This …
Digging Through Discarded Identity: Archaeological Investigations Around The Kitchen And The Overseer's House At Whitney Plantation, Louisiana, Erika Sabine Roberts
Digging Through Discarded Identity: Archaeological Investigations Around The Kitchen And The Overseer's House At Whitney Plantation, Louisiana, Erika Sabine Roberts
LSU Master's Theses
During the mid-nineteenth century, the Haydel family was prominent sugar planters in southern Louisiana. Their plantation, Whitney Plantation (16SJB11), lies on the highway 18 on the west bank of the Mississippi River in Wallace, Louisiana. During the summer of 2002 archaeological investigations were conducted around the kitchen and the overseer’s house, in order to collect a sample of materials associated with these occupants. I hoped that the artifacts could yield information on how the planter and overseer family represented themselves materially. Although what I excavated was the discarded remnants of the Haydel family’s life, these remnants offer an understanding of …
Teaching The Progressive Era Through The Life And Accomplishments Of Jane Addams, Kacy J. Taylor
Teaching The Progressive Era Through The Life And Accomplishments Of Jane Addams, Kacy J. Taylor
LSU Master's Theses
Because of standardized testing in Louisiana, the high school American history curriculum has been reduced to a long list of facts. Students no longer learn the story of American history – the people and events that have defined America as we know it. Instead, it is presented to them in fragmented pieces. Teachers move so quickly from subject to subject that they fail to explain the origin and transformation of ideas. This paper proposes teaching a period of history through the life of an important historical figure, in this case, Jane Addams. Through the life of Jane Addams, students can …

Fracture Behavior Of Wood Plastic Composite (Wpc), Gi Young Jeong
LSU Master's Theses
In this study, the effect of notch length on impact strength and fracture toughness was examined to exploit the use of wood plastic composite (WPC) as structural materials. Impact and fracture toughness test methods and estimation procedures were carried out. To evaluate the impact strength of WPC, five different notch sizes with two different fiber orientations on the load head were prepared. In terms of fracture mechanics, notch length was converted to stress concentration factor and the relationship between stress concentration factor and impact strength was determined. Fracture surface of impact specimens was investigated to evaluate the fracture mechanism of …
Superposition Coding Based Co-Operative Diversity Schemes, Anil Kumar Goparaju
Superposition Coding Based Co-Operative Diversity Schemes, Anil Kumar Goparaju
LSU Master's Theses
With a prefixed decoding order at receiver end, superposition coding approach intended for degraded broadcast channels was proposed to improve the average throughput in a point-to-point wireless channel. In this thesis, we first rigorously show the optimal decoding strategy when two Gaussian codebooks are superposed together to send source information to its receiver. Our results rigorously prove the optimality of performing successive interference cancellation at receiver end. Decoding failure at relays imposes a bottle neck to improving overall throughput in relay channels with decode-and-forward relaying strategy. We then extend this framework for a single link to relay channels to optimize …
Growth Of A Slash Pine Spacing Study Five Years After Thinning, Jamie Camille Schexnayder
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 …
Seasonal Space Use, Habitat Preference And Survival Of Female Wild Turkeys In A Louisiana Bottomland Hardwood Forest, Walker Blake Wilson
Seasonal Space Use, Habitat Preference And Survival Of Female Wild Turkeys In A Louisiana Bottomland Hardwood Forest, Walker Blake Wilson
LSU Master's Theses
Female wild turkeys (Meleagris gallopavo) were captured and radio-marked in a bottomland hardwood forest in south-central Louisiana. Turkeys were monitored using radio telemetry from fixed points on Sherburne Wildlife Management Area, Atchafalaya National Wildlife Refuge, and Bayou des Ourses to observe seasonal patterns of space use, habitat preference and survival from 2002-04. The largest mean seasonal home range of 902.87 ha occurred during preincubation (15 Feb – 9 Apr; n = 24) when females typically search for suitable nest sites, and the smallest mean seasonal home range was 434.12 ha, during brood-rearing (1 Jun – 30 Sep; n = 32) …
Environmental Factors Influencing Incubation Constancy And Recess Frequency In Gadwall (Anas Strepera) In The Prairie Pothole Region Of North Dakota, Nicole F. Lorenz
Environmental Factors Influencing Incubation Constancy And Recess Frequency In Gadwall (Anas Strepera) In The Prairie Pothole Region Of North Dakota, Nicole F. Lorenz
LSU Master's Theses
I examined nest attendance patterns for 132 Gadwall (Anas strepera) females breeding in the prairie pothole region located in Towner County, North Dakota from May to July 2000 - 2001. Overall, Gadwall had a daily incubation constancy of 76.5 ± 10.8%, and daily recess frequency of 2.2 ± 1.1 with each recess lasting 179.8 ± 133.8 minutes. Unlike other waterfowl species, Gadwall increased incubation constancy and decreased recess frequency as daily high temperature increased and showed no change in constancy with precipitation. Gadwall incubation constancy did not fit the body-size hypothesis, as Gadwall have a lower incubation constancy compared to …
