Development Of Non-Dairy Frozen Dessert Containing Soy Protein And Coconut Milk, Luciana Soler Jan 2005

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 …

Ecotoxicology Of Metal-Hydrocarbon Mixtures In Benthic Invertebrates, Kurt A. Gust Jan 2005

Ecotoxicology Of Metal-Hydrocarbon Mixtures In Benthic Invertebrates, Kurt A. Gust

LSU Doctoral Dissertations

Metal-hydrocarbon mixtures are becoming increasingly prevalent in natural environments due to expanding industrial activity and urbanization. The ecotoxicology of metal-hydrocarbon mixtures in benthic environments is of particular concern because both classes of contaminants partition to sediments and can thereby exert toxic effects in benthic organisms. Mixtures of dissimilar chemicals (including metals and hydrocarbons) are broadly hypothesized to elicit independent toxic effects however; this hypothesis has little supporting data. The purpose of this dissertation was to test this hypothesis for metal-hydrocarbon mixtures using environmentally relevant exposures and to determine mechanisms for observed interactive effects. Sediment and water-only bioassays were conducted employing …

Effects Of Spaced Retrieval On Memory And Quality Of Life In Older Adults With Probable Alzheimer's Disease, Karri S. Hawley

LSU Doctoral Dissertations

This study was designed to explore the effects of spaced-retrieval training on memory and quality of life in older adults with probable Alzheimer’s disease. A total nineteen older adults with probable Alzheimer’s disease (AD) participated in these experiments. Experiment one was designed to determine whether the spacing effect is contributing to the success of the spaced-retrieval intervention. Participants were trained to recall a name-face association using either the adjusted spaced-retrieval method or a fixed interval retrieval method. The results showed a more consistent performance profile for the spaced retrieval group in comparison to the fixed interval group, providing evidence that …

Molecular Dynamics Simulations Of Biological Membranes In The Presence Of Cryoprotectants, Dinesh Pinisetty Jan 2005

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 …

After Scotland: Irvine Welsh And The Ethic Of Emergence, Benjamin George Lanier-Nabors Jan 2005

After Scotland: Irvine Welsh And The Ethic Of Emergence, Benjamin George Lanier-Nabors

LSU Doctoral Dissertations

In “After Scotland: Irvine Welsh and the Ethic of Emergence,” the author’s objective is to mirror what he argues is the Scottish writer Irvine Welsh’s objective: to chart out a future Scotland guided by a generative life ethic. In order to achieve this objective, the author lays open and reengages Scotland’s past, discovers and commits to neglected or submerged materials and energies in its past, demonstrates how Welsh’s work is faithful to those and newly produced materials and energies, and suggests that Welsh’s use of those materials and energies enables readers to envision a new Scotland that will be integral …

Martin Heidegger's Phenomenology And The Science Of Mind, Charles Dale Hollingsworth Jan 2005

Martin Heidegger's Phenomenology And The Science Of Mind, Charles Dale Hollingsworth

LSU Master's Theses

Phenomenology and cognitive science present two very different ways of looking at mental activity. Recently, however, there have been some attempts to incorporate phenomenological insights and methods into cognitive science, drawing especially on the works of Martin Heidegger. The purpose of this thesis is to determine if a useful combination of cognitive science with Heidegger’s phenomenology is possible, and to determine the form such a combination might take. This thesis begins with a brief overview of the field of cognitive science, and of some of the problems within the field that might benefit from a phenomenological analysis. It then reviews …

Solitary Blessings: Solitude In The Fiction Of Hawthrone, Melville, And Kate Chopin, Virginia Massie Jan 2005

Solitary Blessings: Solitude In The Fiction Of Hawthrone, Melville, And Kate Chopin, Virginia Massie

LSU Doctoral Dissertations

“Solitary Blessings: Solitude in the Fiction of Hawthorne, Melville, and Kate Chopin” examines a construction of solitude in which nature is alien and perilous, the self confronts rejection and death, the subject is subordinated to an unknown, and the revealed truth is experienced as both gift and curse. Arising out of fictional portraits of people under duress, this interpretation counters a more dominant construction in American literature, enunciated by Edwards, Emerson, and Thoreau, that shows solitude as composed and calming, subordinating nature to mind, and revealing an underlying truth in presentable form. Solitude has been equated with privation and exile …

Population Dynamics Of Clausocalanus Furcatus (Copepoda, Calanoida) In The Northern Gulf Of Mexico, Hongsheng Bi Jan 2005

Population Dynamics Of Clausocalanus Furcatus (Copepoda, Calanoida) In The Northern Gulf Of Mexico, Hongsheng Bi

LSU Doctoral Dissertations

Copepods are important components of marine ecosystems. Understanding copepod population dynamics can help interpret variations in both primary producers and higher trophic levels. Egg production, stage duration, and stage-specific mortality rates are key parameters describing copepod population dynamics. Estimation of stage-specific mortality is complicated due to a complex life history, patchiness, and sampling biases. This study was undertaken to quantify the population dynamics of the copepod Clausocalanus furcatus in the northern Gulf of Mexico and to assess the utility of available mortality estimation methods in a highly advective environment. Zooplankton samples were taken every 12h from March 18-April 6, and …

Serotonin And Stress Responding In Animals: Role Of 5-Ht.2a/C Receptors In The Central And Peripheral Nervous Systems, Sarah Mathews Uzelac

LSU Doctoral Dissertations

Behavioral responses to stressors can be influenced in different ways by both serotonin (5-HT) agonists and antagonists. Further study, of both different stressors as well as different 5-HT agents, is needed to clarify the place of 5-HT in stress responding. To date, no published report has investigated the influence of centrally and/or peripherally administered 5-HT2A/C agonist DOI or the 5-HT2A/C antagonist ketanserin on behaviors evoked by tail pinch or open field stressors. Five separate, related experiments were conducted to investigate this influence. It was hypothesized that that peripherally (Experiment 1), centrally (Experiment 2), and centrally + peripherally (Experiment 3) injected …

Modeling The Fate And Transport Of Chlorinated Benzenes In Baton Rouge Bayou, Sudheer Nimmagadda Jan 2005

Modeling The Fate And Transport Of Chlorinated Benzenes In Baton Rouge Bayou, Sudheer Nimmagadda

LSU Master's Theses

Knowledge of the fate and transport of chlorinated benzenes is necessary at certain sites for effective remediation of contaminated soils using plants. Current research is examining the capability of wetland plants to catalyze degradation or attenuate migration, but again requires knowledge of the uptake of contaminants from an aqueous environment. A two stage model was used to estimate the rate of uptake of contaminants from sediments. The first stage of the model predicts pollutant leaching rates from sediments to the overlying water, which would then be fed into the plant or bioreactor model systems. In this study the flux from …

Aquinas And The Knowledge Of God, Casey Edler Jan 2005

Aquinas And The Knowledge Of God, Casey Edler

LSU Master's Theses

This thesis concerns the introduction of mystical knowledge into a debate about God that relies on scientific evidence. The thesis focuses in particular on the relevance of Thomas Aquinas' view of mystical experience. After first presenting Aquinas' theory of rapture as an anticipation of the beatific vision and distinguishing it from other ways of knowing God, I argue that such a theory convincingly renders mystical knowledge inadmissible into a debate about God that relies on scientific evidence, owing to one's inability to either remember or communicate such an experience. As a result, introducing mystical knowledge into the debate causes the …

Effects Of Ozonation And Addition Of Amino Acids On Properties Of Rice Starches, Hee-Joung An Jan 2005

Effects Of Ozonation And Addition Of Amino Acids On Properties Of Rice Starches, Hee-Joung An

LSU Doctoral Dissertations

In this study, the effects of ozonation and the addition of amino acids on rice starches were determined in terms of pasting properties by using rapid visco-analyzer, thermal characteristics by using differential scanning calorimeter, crystallinity by using x-ray diffraction, and resistant starch yield. Results from viscosity analysis showed that the addition of lysine (6%) to ozonated Sigma rice starch significantly reduced peak viscosity (PV), minimum viscosity (MV), final viscosity (FV), and setback (SBK) by 918, 1024, 1023, and 105 cP, respectively. Moreover, it decreased pasting time, resulting in the faster swelling upon heating and less rigid gel formation upon cooling. …

The Foundation Of An Apparel Factory: Culture's Place Becomes A Practiced Space, Kim T. Chavis Jan 2005

The Foundation Of An Apparel Factory: Culture's Place Becomes A Practiced Space, Kim T. Chavis

LSU Doctoral Dissertations

The study provides a reformulation of culture as space. Building on Michel Certeau's theory of space and place, this study incorporates Karla Holloway's theory of historicity, memory, and metaphor - specifically, how these elements are formed and behave - W.E.B. Dubois's theory of double consciousness, Homi Bhabha's theory of the beyond and interstices, John Fiske's culture of everyday life, Bourdieu's idea of the habitus, Brett Williams' theory of texturing, and Edward Said's travel theory. These critical ideas are woven together to construct an operating construct of space, which allows for that culture to be a dynamic, fluid construction, represented in …

Winter Bird Use Of The Chinese Tallow Tree In Louisiana, Michael John Baldwin Jan 2005

Winter Bird Use Of The Chinese Tallow Tree In Louisiana, Michael John Baldwin

LSU Master's Theses

Chinese tallow (Triadica sebifera) is a non-native invasive tree that is of particular concern in the Southeastern United States. It has become naturalized in a variety of habitats and can be found in monospecific stands. The use of tallow woodlands by overwintering birds is poorly documented. I compared use of tallow woodlands to use of bottomland hardwood forests by birds in the Mermentau River Basin, Louisiana. Species richness and evenness were greater in the bottomland hardwood sites. Three species were more abundant in tallow woodlands, six species were more common in bottomland hardwoods, and six species exhibited no difference between …

Biologically Inspired Learning System, Patrick Mcdowell Jan 2005

Biologically Inspired Learning System, Patrick Mcdowell

LSU Doctoral Dissertations

Learning Systems used on robots require either a-priori knowledge in the form of models, rules of thumb or databases or require that robot to physically execute multitudes of trial solutions. The first requirement limits the robot’s ability to operate in unstructured changing environments, and the second limits the robot’s service life and resources. In this research a generalized approach to learning was developed through a series of algorithms that can be used for construction of behaviors that are able to cope with unstructured environments through adaptation of both internal parameters and system structure as a result of a goal based …

Samuel Beckett And Bilingualism: How The Return To English Influences The Later Writing Style And Gender Roles Of All That Fall And Happy Days, Julien F. Carriere Jan 2005

Samuel Beckett And Bilingualism: How The Return To English Influences The Later Writing Style And Gender Roles Of All That Fall And Happy Days, Julien F. Carriere

LSU Doctoral Dissertations

This dissertation addresses Samuel Beckett's bilingualism in an effort to understand how the author's use of language affected his writing style and depiction of gender. Beckett began writing in English, switched to French for the composition of new works for ten years, and then returned unexpectedly to English. His first English works are characterized by stylistic virtuosity, erudition, and misogyny. With Beckett's adoption of French his style became simple, spare, and cerebral. Plot structure based on a journey in early works was abandoned in favor of static situations and dialogue. Women were either ignored or viewed negatively. In 1956, Beckett …

Conspiracy Culture In America After World War Ii, Valerie Rose Holliday Jan 2005

Conspiracy Culture In America After World War Ii, Valerie Rose Holliday

LSU Doctoral Dissertations

Feminism has all too often been reified as a theoretical category. Specifically, Marxist critical categories fail to account for the integral importance of gender in any sociopolitical critique. This dissertation attempts to dereify gender and demonstrate a theoretical model that seamlessly integrates psychoanalysis, Marxism, and feminism. Conspiracy culture in America since World War II is an ideal aperture through which we may envision such a theoretical approach, and indeed see the critical need for such an approach. This dissertation looks at several post-war American conspiracy narratives, including Oliver Stone’s JFK and Nixon, Don DeLillo’s Libra, Sidney Lumet’s Fail Safe, John …

Estimating The Postmortem Interval In Forensic Cases Through The Analysis Of Postmortem Deterioration Of Human Head Hair, Jamie Hughes Collier Jan 2005

Estimating The Postmortem Interval In Forensic Cases Through The Analysis Of Postmortem Deterioration Of Human Head Hair, Jamie Hughes Collier

LSU Master's Theses

Establishing the postmortem interval (PMI) of a decedent is one of the most important responsibilities a forensic investigator may face. An accurate PMI may aid in the identification of not only the victim, but also a suspect. Although many methods for determining time since death have been proposed, there is still a need to establish more reliable dating techniques. This study determines whether head hair from an individual deteriorates uniformly and if so, what association cuticle damage, fungal growth, and changes in proximal end morphology may have with PMI. Fifteen to 25 scalp hairs were pulled from nine cadavers located …

Racial Variations And Social Support And Its Impact On Stress And Depression, Claire Sam Jan 2005

Racial Variations And Social Support And Its Impact On Stress And Depression, Claire Sam

LSU Master's Theses

Evidence suggests that social support can mitigate some of the harmful effects of stress on health. Social support theorists argue that certain social groups have differential access to social support; therefore, certain social groups are at a higher risk of experiencing psychiatric symptoms. Although social networks are beyond the scope of these analyses, it is an important component to consider when examining the uneven distributions of social support between social groups. If racial differences exist in the networks in which individuals are embedded, then part of the differential access to social support could be explained by examining the various compositions …

Ability Of College Students To Simulate Adhd On Objective Measure Of Attention, Randee Lee Booksh Jan 2005

Ability Of College Students To Simulate Adhd On Objective Measure Of Attention, Randee Lee Booksh

LSU Doctoral Dissertations

Complaints of ADHD symptoms in college students are not uncommon and college students frequently self-refer for assessment of ADHD. Some may seek out a diagnosis to obtain academic accommodations and/or stimulant medication. Diagnosing ADHD in college students is largely reliant on self-report measures, and to a lesser extent, objective measures of attention. The typical college student has easy access to information about ADHD, potentially facilitating efforts to simulate self-reported symptoms. The present study examined the ability of college students to effectively simulate ADHD on objective and self-report measures of attention, and examined the relationship between knowledge of ADHD and ability …

Aspects Of The Life History, Ecophysiology, Bioenergetics, And Population Dynamics Of The Cownose Ray, Rhinoptera Bonasus, In The Northern Gulf Of Mexico, Julie Ann Neer

LSU Doctoral Dissertations

The cownose ray, Rhinoptera bonasus, is an elasmobranch commonly observed throughout the Gulf of Mexico. Cownose rays appear to be sensitive to water temperature. I performed laboratory experiments and collected field data to obtain basic life history information, and used the information to configure an individual-based bioenergetics model. The bioenergetics model was coupled to a matrix projection model, and the coupled models were used to predict how warmer and cooler water temperatures, compared to current conditions, would affect the growth and population dynamics of the cownose rays. The life history study determined weight at age, maturity by weight, and fecundity …
