Numerical Methods For The Study Of Super-Eddington Mass Transfer In Double White Dwarf Binaries, Dominic Carlo Marcello

LSU Doctoral Dissertations

We present a numerical method for the study of double white dwarf (DWD) binary systems at the onset of super-Eddington mass transfer. We incorporate the physics of ideal inviscid hydrodynamical flow, Newtonian self-gravity, and radiation transport on a three-dimensional uniformly rotating cylindrical Eulerian grid. Our new method conserves total energy to a higher degree of accuracy than recent smoothed particle hydrodynamics methods and our previous Eulerian grid based method. We present the results of verification tests and we simulate the first 20+ orbits of a binary system of mass ratio q=0.7 at the onset of dynamically unstable direct impact mass …

"Are You Better Off"; Ronald Reagan, Louisiana, And The 1980 Presidential Election, Matthew David Caillet

LSU Master's Theses

This thesis describes how Ronald Reagan succeeded in carrying Louisiana in the 1980 Presidential election. Initially, pundits predicted the election, both statewide and nationwide, would be a “dead heat” between Reagan and President Jimmy Carter. Southern voters supported Carter, despite his many blunders; many American voters wondered if Reagan would be a competent leader. Reagan had a well-organized campaign and spent plenty of time in Louisiana, considered a pivotal “swing state.” His campaign team prepared speeches, explained issues, and received information and support from state Republican leaders, including Governor David Treen and Congressmen Robert Livingston and Henson Moore. Good local …

Tropical Salvage: From Recession To Expansion, Scott Marshall, Lisa Peifer, Erin Ferrigno

Business Faculty Publications and Presentations

Tim O’Brien, founder of Tropical Salvage, was preparing for another warehouse clearance sale of his unique, handcrafted hardwood furniture. It had been an enormously challenging year and it was important to reduce inventory before the next container arrived from Indonesia. The market for fine furniture had begun to decline steadily in early 2008 following the stock market crash of the prior September. The company survived a difficult period, but not without suffering a decline in sales. O’Brien had spent ten years building a sustainable business model based on environmental stewardship, worker empowerment and unique, high quality product. As the economy …

Wiggle Veil (Or, Love Needs Objects), Adrienne Lynch

LSU Master's Theses

The six sculptural works that comprise my thesis exhibition emerged from a prolonged series of investigations into the intricately interconnected phenomenon of embodied experience in the world as we know it. These works explore the connections between mysteries in our inner and outer worlds, taking as inescapable fact the notion that our bodily vessels, in all their complexity and subtlety, are the vehicles through which we encounter the world. As such, this work posits embodiment as both frame and anchor for all knowledge and experience. These sculptures, made from ceramic materials and mixed media such as sugar, salt, string, and …

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 …

Alternative Pretreatment Of Sorghum Bagasse For Bio-Ethanol Production, Cong Chen

LSU Master's Theses

The majority of the world’s energy needs are currently met through the use of fossil fuels. The possible depletion of fossil fuel resources and environmental concerns has prompted the search for alternative renewable and environmentally friendly energy resources. The goal of this research was to develop a microwave-assisted dilute ammonia pretreatment technology for the conversion of sweet sorghum into ethanol. Conversion of biomass into ethanol requires a pretreatment step to open up the structure and decouple the cellulose, and hemicellulose and lignin in the biomass. In the first study, sorghum bagasse was pretreated with 28% ammonium hydroxide, and water at …

Difficulty Disengaging Attention From Appearance Words Among Women With High Social Anxiety, Jose Silgado

LSU Master's Theses

Pathological eating behaviors (PEB) and body dissatisfaction are more prevalent among women with higher social anxiety (HSA) than women with lower social anxiety (LSA). Attentional bias may play a role in these relationships. Attentional bias toward appearance is related to PEB and body dissatisfaction. Further, difficulty disengaging attention from threat is thought to maintain anxiety among HSA individuals. It follows that some HSA women may find scrutiny regarding their appearance threatening and difficulty disengaging attention from appearance cues may play an especially important role in PEB and/or body dissatisfaction among HSA women. The present study tested this theory, hypothesizing that: …

Functional Analysis Of Nopp140 And P5cdh1 In Drosophila Melanogaster, Fang He

LSU Doctoral Dissertations

Nopp140 is a nucleolar protein with several purported roles in ribosome biogenesis. To further characterize Nopp140 in Drosophila, we used FLP-FRT recombination to delete the Nopp140 gene. Genomic PCR, RT-PCR, and immuno-fluorescence microscopy confirmed the loss of Nopp140 and its products. Compared to embryos bearing the transposons used to generate the deletion, Nopp140-/- embryos displayed similar hatching rates, but resulting larvae died after 8 days, still in the second instar stage. Nucleoli were apparent in Nopp140-/- cells with no observable morphological defects, but the rRNA methyl-transferase, fibrillarin, redistributed partially to the nucleoplasm. BrU-labeling indicated that rDNA transcription is reduced overall …

Information Dissemination For Farming Communities In Thailand, Khumphicha Tantisantisom

Theses: Doctorates and Masters

The use of information and communication technology tools has been applied in many disciplines, including agricultural sectors. It may be applied in many modules such as data gathering, data processing, information management and information dissemination. One issue that cannot be neglected is the readiness of technology service users, or farmers in this case. It was found that most Thai farmers were poor and illiterate; therefore, offering them the best available tools and services may not be always what they would like to use. To answer the research questions, action research methodology was selected in this study to find a practical …

Stability Analysis Of Anchored Rock Slopes Against Plane Failure Subjected To Surcharge And Seismic Loads, Md M. Hossain

Theses: Doctorates and Masters

The stability analysis of rock slopes has been a challenging task for engineers

because the rock mass constituting the slope often has discontinuities in various

forms, resulting in different types of slope failures. The plane failure is one of the

rock slope failures observed in field situations when the discontinuity is in the form

of joint planes. There are several parameters including surcharge and seismic loads

that govern the stability of the rock slope against plane failure in field projects. The

limit equilibrium approach for the estimation of the factor of safety of the rock slope

against plane failure has …

Encroaching On Freedoms? Values Related To Freedom And Readiness To Accept Social Marketing Activities In Australia And Japanese Students, Kaoru Nosaka

Theses: Doctorates and Masters

Do Australian and Japanese university students feel that social marketing is encroaching on their freedoms or empowering them? For example, how do they react to social marketing messages such as ‘Don’t Drink and Drive’ and ‘Reduce, Reuse, Recycle’? Social marketing activities include advocating for environmental change, laws, and regulations as well as making recommendations to individuals to change behaviours to promote the good of society; however, some people believe that such activities are attempts to control people, infringing upon their individual freedom. While behavioural models and theories have recognised the influence of an individual’s predisposition towards a recommended behaviour (such …

Feedback Control For Exergames, Jeff Sinclair

Theses: Doctorates and Masters

The concept of merging exercise equipment with video games, known as exergaming, has the potential to be one of the main tools used in addressing the current rising obesity epidemic. Existing research shows that exergaming can help improve fitness and additionally motivate people to become more active. The two key elements of attractiveness - how much people want to play or use the exergaming system; and effectiveness – how effective the exergaming system is in actually increasing or maintaining physical fitness, need to be maximised to obtain the best outcomes from an exergaming system; we put this forward as the …

Internet Use And Its Impact On Secondary School Students In Chiang Mai, Thailand, Kesaraporn Wanajak

Theses: Doctorates and Masters

Internet addiction (IA) is a relatively new field of academic inquiry. Empirical studies suggest that IA, like other well researched addictive behaviours, has an effect on many aspects of a person‟s life, including academic/work performance, relationships, and physical and mental health (Goldberg, 1996; Young, 1996, 1998). Evidence of IA has been suggested by the findings that some Internet users spend increasingly longer periods of time online and experience withdrawal symptoms when offline. Those preoccupied with Internet-related activities may neglect exercise, family and social activities (Kim et al., 2010; Nalwa & Anand, 2003; Seo, Kang, & Yom, 2009; S. Yang & …

Re-Presenting Gender Fluid Identity In A Contemporary Arts Practice, Matthew Jackson

Theses: Doctorates and Masters

This dissertation addresses the paucity of representation of gender fluid identity within contemporary imagery. An examination of historical and socio-political structures inherent in modern Western society serves as a foundational position for a broader exploration of differently gendered communities globally. The case is made for contemporary art to be encouraged as a tool for the emancipation of subjugated gender fluid identities. Examples of contemporary gender fluid visual art and artists are presented to illustrate the ability of art to enable agency within the broader gender fluid community. Finally, a commentary on my own artwork is presented and discussed in relation …

Comparison Of A Novel Fluorogenic Anti-Fxa Assay With A Central Laboratory Chromogenic Anti-Fxa Assay For Measuring Lmwh Activity In Patient Plasmas, Leanne F. Harris, Vanessa Castro-Lopez, James S. O'Donnell, Anthony J. Killard

Articles

Introduction: Low molecular weight heparins (LMWHs) are used worldwide for the treatment and prophylaxis of thromboembolic disorders. Routine laboratory tests are not required due to the predictable pharmacokinetics of LMWHs, with the exception of pregnant patients, children, patients with renal failure, morbid obesity, or advanced age. Anti-Factor Xa (anti-FXa) plasma levels are most often employed in the assessment and guidance of accurate dosing in these patient cohorts. Materials and methods: A LMWH calibration curve was generated using citrated human pooled plasma spiked with pharmacologically relevant concentrations (0–1 U/ml) of two low molecular weight heparins; enoxaparin and tinzaparin. Least squares analysis …

Cooperative Learning And Peer Tutoring To Improve Third-Grade Students’ Test Scores On Grade-Level Assessment, Francina Y. Thurston

Abraham S. Fischler College of Education ETD Archive

This applied dissertation was designed to utilize learning strategies that emphasized small-group instructions where students work together cooperatively and with peers to achieve mastery. Traditionally, the classroom practices used in this school lent themselves primarily to whole-class instructions that emphasized competitive and individualistic goals rather than small groups and cooperative practices. The multistrategy used in this study sought to shift the focus of classroom instructions away from what was traditional. However, the introduction of the multistrategy that called for small group teaching required training for teachers and students.

The writer developed several solution strategies that trained students and teachers in …

One Pot Synthesis Of Metal, Carbides And Polymeric Aerogels, Naveen K. Chandrasekaran

Doctoral Dissertations

"Ultra-low density, three-dimensional assemblies of nanoparticles are referred to as aerogels, and typically are derived from supercritical fluid (SCF) drying of wet-gels. Aerogels are generally fragile materials, but that issue has been addressed successfully by X-aerogels, in which the inorganic nanoparticle framework plays the role of the template for the accumulation of polymer that connects covalently and crosslinks the nanoparticles. The resulting materials can be 300x stronger than the native network, for a nominal increase in density by a factor of 3x. Since the exceptional mechanical properties of X-aerogels are traced to the conformal polymer coating, it was reasonable to …

Naturalistic Emotional Speech Corpora With Large Scale Emotional Dimension Ratings, Brian Vaughan

Doctoral

The investigation of the emotional dimensions of speech is dependent on large sets of reliable data. Existing work has been carried out on the creation of emotional speech corpora and the acoustic analysis of emotional speech and this research seeks to build
upon this work while suggesting new methods and areas of potential. A review of the literature determined that a two dimensional emotional model of activation and evaluation was the ideal method for representing the emotional states expressed in
speech. Two case studies were carried out to investigate methods of obtaining natural
underlying emotional speech in a high quality …

Links Between Parents' And Children's Levels Of Gratitude, Life Satisfaction, And Hope, Brenna D. Hoy

USF Tampa Graduate Theses and Dissertations

Positive psychology encourages a focus on identifying and promoting wellness in individuals rather than analyzing psychopathology. Although decades of research shows that mental illness is in part environmental and hereditary, little is known about the relationship between parental levels of positive emotions such as gratitude, life satisfaction, and hope, and their children's levels of the same constructs. This study utilized a past, present, and future framework of positive emotions to explore parental and child levels of gratitude, life satisfaction, and hope. This quantitative study analyzed correlations between self-reported levels of gratitude, life satisfaction, and hope among a sample of 153 …
