An Experimental Investigation Of Corrosion Fatigue Life Via Thermographic Method, Richard Wayne Purvis Jan 2014

An Experimental Investigation Of Corrosion Fatigue Life Via Thermographic Method, Richard Wayne Purvis

LSU Master's Theses

The effect of prior corrosion fatigue damage on the thermographic response of 1018 low carbon steel is investigated. Specimens were subject to rotating bending fatigue at 38 Hz loading frequency while being exposed to a 3.5% NaCl and distilled water solution. Some specimens were subject to corrosion fatigue for part of their fatigue life and then their thermographic response measured under fatigue in air at 62 Hz loading frequency. Fatigue tests in air with thermographic measurement were performed as a comparison. It was observed that the initial temperature rise after corrosion fatigue fits the previously proposed model for air fatigue, …

Everything Is Alright: Parental Positive Impression Management In Assessment Of Anxious Youth, Megan Elizabeth Kirkpatrick Jan 2014

Everything Is Alright: Parental Positive Impression Management In Assessment Of Anxious Youth, Megan Elizabeth Kirkpatrick

LSU Master's Theses

Lifetime prevalence rates of anxiety disorders in youth are substantial and range from 6-15%. Valid evidence-based assessments are therefore of critical importance in screening pediatric clients. Assessment of childhood disorders requires multi-informant data (e.g., parents, teachers, child); however, this presents a host of obstacles not found in adult assessment. No single source represents the gold standard and it is therefore up to the judgment of the clinician to integrate often conflicting information. Parents’ reports of their children's symptomology may be marred by their own anxious or depressive symptoms as well as conflict due to differing motivations, values, and goals. This …

Administrator Perceptions Of Intramural Coed Flag Football Modifications: A Qualitative Analysis, Zacharias Wood Jan 2014

Administrator Perceptions Of Intramural Coed Flag Football Modifications: A Qualitative Analysis, Zacharias Wood

LSU Master's Theses

Coed sport environments can be paradoxical settings where pre-existing gender biases influence participants’ enjoyment and success. Furthermore, gendered messages and stereotypes as well as low expectations for females within coed sports can create participation barriers by reducing feelings of confidence and performance. Within Campus Recreation, intramural sport administrators have a significant role in determining participation opportunities and experiences. This investigation examined administrators’ perspectives about coed intramural flag football gender modifications. Specifically, three research questions guided this study: (a) how do intramural administrators view coed flag football gender modifications?; (b) to what extent do intramural administrators perceive gender modifications to impact …

Integrating Recycled Glass Cullet In Asphalt Roof Shingles To Mitigate Heat Island Effect, Micah Kiletico Jan 2014

Integrating Recycled Glass Cullet In Asphalt Roof Shingles To Mitigate Heat Island Effect, Micah Kiletico

LSU Master's Theses

As an approach to mitigate the harmful effects of Urban Heat Island (UHI), the use of glass cullet in the production of asphalt roof shingles has the potential to be employed as a cool roof strategy. The objective of this study was to test the hypothesis that the use of recycled glass increases solar reflectance index (SRI) without affecting the performance of asphalt roof shingles. In order to evaluate the feasibility of recycled glass for alternative uses, the engineering properties of glass cullet were investigated and compared to conventional aggregates used in the production of asphalt roof shingles. Laboratory samples …

Hacia Una Anatomía Del Textum: Corporalidad Y Discurso En El Cine Contemporáneo Argentino., Guillermo Abel Severiche Jan 2014

Hacia Una Anatomía Del Textum: Corporalidad Y Discurso En El Cine Contemporáneo Argentino., Guillermo Abel Severiche

LSU Master's Theses

En la introducción de su libro The Body in Pain, Elaine Scarry afirma que “cuando uno escucha acerca del dolor físico de otra persona, los eventos que tienen lugar en el interior del cuerpo de esa persona parecen tener el carácter remoto de un hecho profundamente subterráneo” (3). Podríamos tomar este postulado y transportarlo a otras formas de la corporalidad: cuando el cuerpo se excita sexualmente, cuando el cuerpo se enferma. En parcial oposición al pensamiento de Scarry, el propósito fundamental del presente estudio es comenzar a darle forma a un concepto que encapsule la dimensión interna del cuerpo junto …

Damage Evolution In Pressurized Domain: A Gradient Based Variational Approach, Navid Mozaffari Jan 2014

Damage Evolution In Pressurized Domain: A Gradient Based Variational Approach, Navid Mozaffari

LSU Master's Theses

Construction of appropriate models through mathematical analysis for materials in order to find their main properties and ingredients and enhance the numerical simulations to predict their behavior under specific conditions is in interest even in mathematics departments rather than material science and engineering branches. Among these models, gradient damage models have reached to the specific stage because of their ability to bring the effects of micro cracks propagation into conventional continuum mechanics formulation and approximate brittle fracture as one of the most phenomena in the area of material behavior simulation. This thesis includes the application and extension of a previously …

Quantifying Phase Configuration Inside An Intact Core Based On Wettability Using X-Ray Computed Tomography, Dinara Dussenova Jan 2014

Quantifying Phase Configuration Inside An Intact Core Based On Wettability Using X-Ray Computed Tomography, Dinara Dussenova

LSU Master's Theses

The ability to evaluate rock and fluid properties on the order of a few microns opens new areas in reservoir engineering and reservoir simulation. Multiple studies have been done on the application of x-ray computed tomography (microCT) for the pore-scale evaluation of fluid interfaces and rock-fluid interaction. A majority of the fluid flow governing interactions occur at the pore scale level and is usually overseen on large reservoir scales. Hence, it is important to carefully investigate such interactions. Multi-fluid-phase distribution and interaction of two immiscible fluids such as oil and water is one of the most important and constantly investigated …

Examination Of The Differential Effectiveness Of Interdependent And Dependent Group Contingencies In Reducing Disruptive Behavior In The Classroom, Kelsey Lynn Hartman Jan 2014

Examination Of The Differential Effectiveness Of Interdependent And Dependent Group Contingencies In Reducing Disruptive Behavior In The Classroom, Kelsey Lynn Hartman

LSU Master's Theses

Disruptive behavior in the classroom negatively affects all students’ academic engagement, achievement, and behavior. Group contingencies have been proven effective in reducing disruptive behavior as part of behavior interventions in the classroom. The Good Behavior Game is a classwide intervention that employs an interdependent group contingency to diminish disruptive behavior. Previous research comparing the effects of the different group contingencies has been inconclusive, inconsistent or unable to rule out sequence effects. This study employed an alternating treatments design across 3 elementary classrooms to compare the effectiveness of interdependent and dependent group contingencies in decreasing disruptive behavior. Results showed that the …

The Adoption Of State Wetland Policies: How Do Wetlands Fit Within The Theoretical Framework Of Environmental Policy Determinants?, Rachel Bogart Krech Jan 2014

The Adoption Of State Wetland Policies: How Do Wetlands Fit Within The Theoretical Framework Of Environmental Policy Determinants?, Rachel Bogart Krech

LSU Master's Theses

Wetlands are an extremely important natural resource in the United States. They offer storm surge protection, sediment stabilization, groundwater recharging, carbon sequestration, and habitat for many species. Despite their values, wetlands have a long history of being misunderstood. It was not until the mid-1970s that scientific understanding helped transform policy from that of rapid conversion to that of conservation. By this time, the lower 48 states had already lost 53 percent of its total wetlands. The nature of wetlands and federal limitations make the management of this natural resource a primarily state-based responsibility. However, the way that states construct their …

L'Envers De L'Histoire De Jacques Collin: On A New Approach To Balzac's Most Infamous Criminal Mastermind, Lauren Elise Pendas Jan 2014

L'Envers De L'Histoire De Jacques Collin: On A New Approach To Balzac's Most Infamous Criminal Mastermind, Lauren Elise Pendas

LSU Master's Theses

Scholarship has failed to explore adequately how Honoré de Balzac evokes the human condition’s universal elements through his most infamous criminal mastermind: Jacques Collin, alias Vautrin. Unlike analyses of Collin that I have encountered, this thesis takes all three novels and the obscure play in which Collin appears into account, challenges the transparency of his statements and the narration’s descriptions of him, explores the conservative position framing Balzac’s critique of early nineteenth-century Paris, and actively focuses on evidence of Collin’s typical subjectivity (i.e. his insatiable desire and fallibility). Consequently, this reading does not evaluate Collin’s significance solely through his apparent …

Experimental Assessment Of Expandable Casing Technology As A Solution For Microannular Gas Flow, Darko Kupresan Jan 2014

Experimental Assessment Of Expandable Casing Technology As A Solution For Microannular Gas Flow, Darko Kupresan

LSU Master's Theses

Microannular gas flow in the wellbore is known to be one of the major reasons for Sustained Casing Pressure (SCP). Low success rate (under 50%) of costly remedial cementing operations and increasing difficulty in sealing off problematic areas motivated the industry to look for more practical remediation solutions. Expandable casing technology is one of those new proposed techniques. A bench-scale physical model tested the potential of expandable casing technology for remediation of microannular gas migration. The composite samples with pipe-inside-pipe cemented annulus were designed to simulate a wellbore system including a pre-manufactured microannulus on the inner pipe/cement interface. Multi-rate flow-through …

Exploring Influences On Gender Equality In Photojournalism: Is The Field Picture-Perfect?, Andrea Briscoe Jan 2014

Exploring Influences On Gender Equality In Photojournalism: Is The Field Picture-Perfect?, Andrea Briscoe

LSU Master's Theses

America prides itself on having a free press. Ideally, this free press would look like the communities in which they cover. However, research shows that gender discrepancies are quite common in newsrooms (Anderson 2014; Briscoe 2012; Norris 1997; Willnat and Weaver 2014). Women often have a marginal presence in newsrooms, and this is troublesome, because scholars have noted that men and women approach newsgathering and reporting differently (Beam and Cicco 2010; Briscoe 2012; Grabe et al. 2011; Weaver 1997). While research has focused on gender discrepancies in various types of media, little to no research has looked at the field …

Cdom Optical Properties Near Dwh Site, Gulf Of Mexico: Pot Oil Spill, Zhi Li

LSU Master's Theses

The Deep Water Horizon (DWH) oil spill resulted in the largest accidental release of crude oil in U.S. waters with both short- and long-term effects on the marine environment. Extensive studies conducted immediately following the oil spill in the northern Gulf of Mexico provided greater understanding of the physical processes influencing the distribution of the released oil, including the use of optical detection of polycyclic aromatic hydrocarbons (PAHs), a toxic crude oil fraction in the northern Gulf of Mexico. In this study, the optical properties of chromophoric dissolved organic matter (CDOM) and the concentrations of dissolved organic carbon (DOC) were …

Early Horizon Defensive Structures And The Role Of Warfare In The Lower Nepeña Valley, Peru, James Steven Treloar Jan 2014

Early Horizon Defensive Structures And The Role Of Warfare In The Lower Nepeña Valley, Peru, James Steven Treloar

LSU Master's Theses

In this thesis I examine the presence and distribution of defensive structures in Nepeña, Ancash, Peru, during the Early Horizon (ca. 900-200 B.C.). Data are gathered from pedestrian surveys, GPS coordinates, drawings, and photographs. I analyze architectural and spatial data using Geographic Information Systems (GIS) tools. I integrate these methods to investigate the organization and distribution of defensive structures in the lower Nepeña, in particular at the archaeological complexes of Caylán, Samanco, and Huambacho. Caylán is a multi-component archaeological complex with a major Early Horizon occupation, and serves as the primary site while the others are used to draw a …

The Effect Of Cooking Methods On The Quality Of Refrigerated And Frozen Whole Crawfish Procambarus Clarkii Girard And Procambarus Zonangulus, John Bradley Shackelford

LSU Master's Theses

Louisiana is famous for its diverse food, culture, and festivals. Crawfish are synonymous with Louisiana cuisine. Approximately 90% of the crawfish harvested in the United States are harvested in Louisiana, but their availability is seasonal (NOAA 2014). Both in-state and out-of-state demand for whole cooked crawfish and for their availability outside the normal harvest season has increased. There is interest from crawfish processors on whether or not steaming of crawfish results in a higher yield than boiling, as traditionally done. This study measures yield, quality parameters, and shelf life of whole boiled and steamed crawfish held in either refrigerated or …

Engineering Behavior And Characterization Of Biomass Ashes Using Geotechnical Measurement Techniques, Francisco Javier Grau Sacoto Jan 2014

Engineering Behavior And Characterization Of Biomass Ashes Using Geotechnical Measurement Techniques, Francisco Javier Grau Sacoto

LSU Master's Theses

Biomass, the organic material derived from plants or animals in a biological process, has rapidly become a topic of worldwide interest. The need to find new types of renewable energy sources has led to the use of natural materials as an economic, sustainable and environmental alternative. Biomass can be used to produce biofuel after a conversion process. The combustion of biomass matter –which is mainly produced in industrial plants- becomes biomass ash, which contains macronutrients and micronutrients. Currently, the recycling potential is wasted and most of the biomass ash is dumped without control or just disposed in landfills. The main …

The Moderating Effect Of Gender On The Relationship Between Socialization And Internalizing Problems In Early Childhood, Hilary Lynn Adams Jan 2014

The Moderating Effect Of Gender On The Relationship Between Socialization And Internalizing Problems In Early Childhood, Hilary Lynn Adams

LSU Master's Theses

Researchers in the field of Autism Spectrum Disorders (ASD) have confirmed that comorbidities are a common problem among diagnosed individuals. Current estimates suggest that more than two thirds meet criteria for an additional diagnosis of psychopathology. In particular, rates of several internalizing problems (i.e., anxiety, depression) appear to be greater for individuals with ASD than their typically developing counterparts. However, little research has been conducted examining factors apart from autism symptomatology that could influence this prevalence difference. Additionally, it is well established that anxiety and depression are more common in females than males in the general population. However, few studies …

Piercing Privilege: Confronting The White Problem Through Autoethnography, Destiny Marie Adams Cooper Jan 2014

Piercing Privilege: Confronting The White Problem Through Autoethnography, Destiny Marie Adams Cooper

LSU Master's Theses

In this reflexive autoethnography, the author explores the “White Problem” by examining narratives of personal transformation resulting from her involvement in Dialogue on Race Louisiana (DORLA), an “educational process for the elimination of race.” The main query of this piece is: How has the author’s relationship to whiteness worked to reify or trouble the “White Problem?” Using writing as a method of inquiry, the author recounts several pivotal experiences that correspond to DORLA’s Original Six Week Series session topics and exhibit personal transformations in her interpretations of racism. After defining the research process, design, and product in Chapter One, the …

The New Orleans Murder Epidemic: Emmanuel Levinas And Jacques Derrida On The Irresponsibility Of Violence, Jacqueline Nicole Zimmer Jan 2014

The New Orleans Murder Epidemic: Emmanuel Levinas And Jacques Derrida On The Irresponsibility Of Violence, Jacqueline Nicole Zimmer

LSU Master's Theses

Corruption, unfettered violence, and racist enforcement tactics have historically defined the operations of the New Orleans Police Department, and consequently, many New Orleanians do not expect to be helped or protected by law enforcement or the justice system. The breakdown of society’s civil code explains why many New Orleans citizens have normalized the use of coercive violence to solve interpersonal disputes instead of relying on legitimate policing methods to maintain social order. In the past year, the city of New Orleans has implemented criminologist David Kennedy’s Group Violence Reduction Strategy (GVRS), which aims to decrease the city’s historically high murder …

The Effect Of Habituation And Changes In Cognition On Anxious Children's Performance On The Wisc-Iv, Franziska Noack Jan 2014

The Effect Of Habituation And Changes In Cognition On Anxious Children's Performance On The Wisc-Iv, Franziska Noack

LSU Master's Theses

Researchers have shown that children with anxiety disorders perform worse on intelligence tests than children with no diagnosable disorders. At this point, two theories have been put forth to describe the direction of this relationship: anxiety results in lowered test performance, and underlying cognitive deficits result in the development of anxiety. Lowered test performance as a result of anxiety may either be due to attention-deficits due to state anxiety or anxiety-elicited difficulties with long-term retention and learning. The purpose of this study was to further examine the first theory: that clinical levels of anxiety can hamper intelligence test performance in …
