Thiol-Ene Scaffolds As Synthetic Augments And Silicate Ceramics As Osteogenic Components For Bone Tissue Engineering Applications, Cong Chen Jan 2015

Thiol-Ene Scaffolds As Synthetic Augments And Silicate Ceramics As Osteogenic Components For Bone Tissue Engineering Applications, Cong Chen

LSU Doctoral Dissertations

Bone tissue engineering approaches using polymer/ceramic composites show promise as effective biocompatible, absorbable, and osteoinductive materials. A novel class of in situ polymerizing thiol-acrylate based copolymers synthesized via an amine-catalyzed Michael addition was studied for its potential to be used in bone defect repair. Both pentaerythritol triacrylate-co-trimethylolpropane tris(3-mercaptopropionate) (PETA-co-TMPTMP) and PETA-co-TMPTMP with hydroxyapatite composites were fabricated in solid cast and foamed forms. These materials were characterized chemically and mechanically followed by an in vitro evaluation of the biocompatibility and chemical stability in conjunction with human adipose-derived mesenchymal pluripotent stem cells (hASC). The solid PETA-co-TMPTMP with and without hydroxyapatite (HA) exhibited …

Regulation Of The Chloride Store In The Retinal Amacrine Cells, Vijai Krishnan Jan 2015

Regulation Of The Chloride Store In The Retinal Amacrine Cells, Vijai Krishnan

LSU Doctoral Dissertations

Nitric Oxide (NO) is a key gaseous messenger that has been shown to be produced by multiple cell types in the vertebrate retina. Research in our lab is aimed at unlocking critical synaptic functions of NO. A major finding from our lab is that NO affects synaptic responses in amacrine cells by altering the plasma membrane gradient for Cl-. This is due to release of Cl- from an internal store and this in turn dependent on a decrease in cytosolic pH. Determining the factors regulating cytosolic Cl- in neurons is fundamental to our understanding of the function of GABAergic and …

Articulating Situated Knowledge And Standpoints In Our Responses To Contemporary Street Fiction: A Book Club Case Study With African American Women, Yvette Rachele Hyde Jan 2015

Articulating Situated Knowledge And Standpoints In Our Responses To Contemporary Street Fiction: A Book Club Case Study With African American Women, Yvette Rachele Hyde

LSU Doctoral Dissertations

Contemporary street fiction is a form of literature that has been growing in popularity since the 1990s. Such novels are set in contemporary urban contexts and present the experiences of historically oppressed groups. Sold in venues such as independent bookstores, the Internet, barbershops, beauty salons, flea markets, street vendors, and churches (Hill, Pérez, & Irby, 2008; McClellan, 2011), this genre is especially popular among African American females. Because much of the scholarship concerning engagement with contemporary street fiction focuses on improving school literacy skills, the purpose of this study was to investigate readers’ responses in a book club held at …

Musicking New Orleans Street Musicians: A Methodology For Writing About Music, Savannah Cadi Rose Ganster Jan 2015

Musicking New Orleans Street Musicians: A Methodology For Writing About Music, Savannah Cadi Rose Ganster

LSU Doctoral Dissertations

This project argues for the use of performative writing as a methodology for writing about musical performances. An analysis of recent scholarship on music and musical performances written by performance studies scholars supports the use of performative writing in texts that address musical performances. In order to further this methodological claim, this study uses performative writing to document both historical and present day accounts of musical performances of street musicians in New Orleans. Utilizing Foucault’s theories on and Roach’s model of genealogy, Bruner’s notion of reflexive ethnography, and Small’s concept of musicking, I theorize, on a meta-methodological level, that performative …

The Rhetorical Function Of Laugh Tracks In Situation Comedies: Examining Queer Shame In Will & Grace And Roseanne, Jimmie Manning Jan 2015

The Rhetorical Function Of Laugh Tracks In Situation Comedies: Examining Queer Shame In Will & Grace And Roseanne, Jimmie Manning

Faculty Articles, Papers, and Other Scholarship

I examine laugh track use in two highly popular television programs, Will & Grace and Roseanne, to consider how the construction of what is or is not supposed to be funny has rhetorical implications for queer identities and relationships. These texts were selected not only for their abundance of queer characters—Will & Grace focused on a gay man/straight woman best friend relationship and Roseanne featured at least one queer character each year beginning with the third season—but also because of their immense popularity. I argue that these two programs constitute what I call enduring popular culture texts, popular entertainment that …

Going Off To The War In Hungary: French Nobles And Crusading Culture In The Sixteenth Century, Brian Sandberg Jan 2015

Going Off To The War In Hungary: French Nobles And Crusading Culture In The Sixteenth Century, Brian Sandberg

Faculty Articles, Papers, and Other Scholarship

Crusading culture played a significant role in the conceptions and practices of religious warfare in the Early Modern Period, as French authors and militant nobles redeployed Hungary as a crucial theater of crusading war. Examining crusading warfare in Hungary reveals new facets of warrior nobles’ military activities in early modern France and abroad, building on recent studies of French noble culture. The article concludes that French readers developed notions of crusading warfare in part through reports of the war in Hungary, contributing to a burgeoning literature on the production, diffusion, and reception of early modern news and information across Europe.

Towards A New Paradigm Of Judicial Education, Mary R. Russell Jan 2015

Towards A New Paradigm Of Judicial Education, Mary R. Russell

Journal of Dispute Resolution

When talking about judicial education, a central question emerges: What is the goal of judicial education for judges? A simple answer springs to mind: To make us better judges, of course. This of course is a deceptively simple question with a deceptively simple answer, until there is an attempt to specifically identify how to accomplish this worthy judicial education goal, and that is where simplicity disappears

Judicial Education: Pedagogy For A Change, T. Brettel Dawson Jan 2015

Judicial Education: Pedagogy For A Change, T. Brettel Dawson

Journal of Dispute Resolution

Canadian judges have maintained a steadfast, long-term commitment to judicial education. Through teaching one another, judges renew their vision over time, and more concretely, address their concerns and challenges today. Since its inception in 1985, the National Judicial Institute (NJI) has sought to be a partner and a resource to judges and Courts in a shared endeavour to create relevant, practical, and effective judicial education. Working together, the NJI, judges, and Courts have built a “Canadian model” of judicial education widely respected and emulated.

Let Me In: The Right Of Access To Business Disputes Conducted In State Courts, David W. Brown Jan 2015

Let Me In: The Right Of Access To Business Disputes Conducted In State Courts, David W. Brown

Journal of Dispute Resolution

After examining the history of the First Amendment right of access to civil proceedings, this note will analyze how the two-pronged historical test applies to arbitrations conducted in a state court. The prongs of the test — experience and logic — provide the framework for the analysis conducted in this note.6 This note argues the analysis conducted in Strine was the correct approach, and suggests the implementation of Sunshine Laws similar to those in other states as a constitutionally permissible alternative that would satisfy the holding in Strine.

The Effects Of Prostatic Fluid On Functional Characteristics Of Cooled Canine Semen, Reto Fritsche Jan 2015

The Effects Of Prostatic Fluid On Functional Characteristics Of Cooled Canine Semen, Reto Fritsche

LSU Master's Theses

The objectives of this study were to investigate concentration dependent effects of canine prostatic fluid (PF) on in vitro seminal parameters of cooled canine semen. Sperm motility parameters, plasma membrane integrity and stability, acrosome integrity and DNA fragmentation were measured after the addition of 0%, 10%, 25%, or 50% PF to extended semen of fertile dogs. Assessments were made at 0 h pre-cooling, at 24, and 48 h of cooled storage (4 °C), and after freezing and thawing followed by incubation (37 °C) at 0, 4 and 24 h. Our hypothesis was that lower dilutions of canine semen with PF …

Salt Tolerance Of Lactococcus Lactis R-604 As Influenced By Exposure To Various Stress Conditions, Ernesto Emilio Gonzalez Duran Jan 2015

Salt Tolerance Of Lactococcus Lactis R-604 As Influenced By Exposure To Various Stress Conditions, Ernesto Emilio Gonzalez Duran

LSU Master's Theses

Lactococcus lactis is a dairy culture bacterium widely used in dairy products that contain salt (NaCl) such as cheese and salted butter. Osmotic conditions generally hinder the growth of both pathogen and desirable bacteria. It has been observed that many stress-induced proteins are produced after exposure to an environmental stress protecting the cell against other stresses since the first exposure starts the defense mechanisms of the cells creating an effect of cross-protection. If salt tolerance is enhanced in desirable bacteria they would survive better in salty environments. The objective of this study was to evaluate the salt tolerance of Lactococcus …

Heat Transfer Study Of Porous Media With A Temperature Jump Condition, Pravin Kumar Jan 2015

Heat Transfer Study Of Porous Media With A Temperature Jump Condition, Pravin Kumar

LSU Master's Theses

Conjugate heat transfer in a porous media is investigated with a temperature jump condition obtained from kinetic gas theory. The temperature jump appears alongside flow boundary condition when the pressure is low, and considered to be in non-continuum regime. This investigation focuses on both one-dimensional and two-dimensional porous media models. The length scale of the pores is 100 microns. The temperature is ambient, and the pressure is low enough to reach the slip-flow regime. The thermal behavior of porous media is investigated using a slot model with a gas trapped between two solid blocks. Aluminum oxide and air are considered …

Mechanisms Controlling Stem Cell Differentiation, Tran Doan Ngoc Tran Jan 2015

Mechanisms Controlling Stem Cell Differentiation, Tran Doan Ngoc Tran

LSU Doctoral Dissertations

Mesenchymal stem cells are multipotent cells that can differentiate into many cell types. However, the molecular mechanism controlling this process remains unclear. We utilized rat dental follicle stem cells (rDFSCs) and human adipose derived stem cells (hASCs) to study the mechanisms controlling osteogenesis and adipogenesis. Elevations in the intracellular Ca2+ concentration are a phenomenon commonly observed during stem cell differentiation but cease after the process is complete. The Transient Receptor Potential Melastatin 4 (TRPM4) is an ion channel that controls Ca2+ signals in excitable and non-excitable cells. However, there are no studies on TRPM4 in stem cells. In another study, …

Development Of New Linking Chemistry With The Fac-{Re(Co)3}+ Core For Eventual Applications In Radiopharmaceuticals In Imaging And Therapy, Aponsu Meregngna Pramuditha Lakmi Abhayawardhana

LSU Doctoral Dissertations

The facile labeling of biomolecules with a radionuclide is a key goal in radiopharmaceutical development. This study explores two different ligand systems for fac-[Re(CO)3L]+ complexes, that could be used in bioconjugation. The first approach uses a tridentate ligand having a sulfonamide linkage and modeled on previously evaluated fac-[Re(CO)3(N(SO2R)dpa)]PF6 complexes. The present goal was to develop new related sulfonamide complexes with more hydrophilic ligands designed to avoid the bioavailability problems that would plague the N(SO2R)dpa ligand system. A series of fac-[Re(CO)3(N(SO2R)dien)]PF6 complexes with different R groups linked to the central nitrogen of a symmetric tridentate sulfonamides were synthesized with the aim …

Analyses Of The Mec1 Dna Damage Pathway In Saccharomyces Cerevisiae, William Barrett Ainsworth Jan 2015

Analyses Of The Mec1 Dna Damage Pathway In Saccharomyces Cerevisiae, William Barrett Ainsworth

LSU Doctoral Dissertations

Eukaryotic organisms implement conserved surveillance machinery to sense and respond to DNA damage. Fundamental to the repair process is coordinated regulation of repair genes and initiation of cell cycle arrest protocols. Failure to preserve these checkpoints results in accumulation of mutated DNA and aberrant cell phenotypes that are characteristic of human disease. The yeast, Saccharomyces cerevisiae, utilizes the MEC1 checkpoint pathway to regulate the DNA damage response. This study addressed two overarching themes of transcriptional and post-translational regulation within the MEC1 pathway. We first applied our understanding of the MEC1 DNA damage transcriptional response to develop advanced luciferase whole cell …

Context Aware Textual Entailment, Soha Arab-Khazaeli Jan 2015

Context Aware Textual Entailment, Soha Arab-Khazaeli

LSU Doctoral Dissertations

In conversations, stories, news reporting, and other forms of natural language, understanding requires participants to make assumptions (hypothesis) based on background knowledge, a process called entailment. These assumptions may then be supported, contradicted, or refined as a conversation or story progresses and additional facts become known and context changes. It is often the case that we do not know an aspect of the story with certainty but rather believe it to be the case; i.e., what we know is associated with uncertainty or ambiguity. In this research a method has been developed to identify different contexts of the input raw …

Correlation Of Ultrasonographic Small Intestinal Wall Layering With Histology In Normal Dogs, Alexandre Benjamin Le Roux Jan 2015

Correlation Of Ultrasonographic Small Intestinal Wall Layering With Histology In Normal Dogs, Alexandre Benjamin Le Roux

LSU Master's Theses

Five intestinal layers are commonly described ultrasonographically in dogs. However, current high-frequency endosonography allows the identification of 9 layers in people. The aim of this study was to describe ex vivo small intestinal layering in dogs and correlate ultrasonographic layering with histological layers. Our hypothesis was that, similar to findings in humans, discrepancies exist in thickness and visibility of intestinal layers between histology and ultrasound in dogs. Twelve adult dogs were included in the study. They were euthanized for reasons unrelated to gastrointestinal disease, but extensive medical history was unavailable. Duodenum, jejunum and ileum samples were resected immediately after euthanasia. …

Modelling Of Channelization In Unconsolidated Formations Due To Liquid Injection, Juan Felipe Bautista Barake Jan 2015

Modelling Of Channelization In Unconsolidated Formations Due To Liquid Injection, Juan Felipe Bautista Barake

LSU Master's Theses

Fluid injection has been increasingly implemented in oil and gas producing fields to optimize hydrocarbon production in both young and mature oil fields across the globe. This situation arises from the realization that early planning of second and tertiary recovery methods may improve project economics significantly. Injectors are then intended to perform at high injection rates with low bottomhole flowing pressures for as long as possible. In the case of injectors drilled in unconsolidated formations, deficient performance often times seems to be the norm. With a majority of these fields being offshore developments in which capital expenditures are high, a …

Natural Order: The Case For Applying Biomimetic Design Principles To Mass Communication Technology Design, William Glass Jan 2015

Natural Order: The Case For Applying Biomimetic Design Principles To Mass Communication Technology Design, William Glass

LSU Master's Theses

In this paper I tested the effectiveness of a biomimetically designed classifier algorithm in an effort to support a new argument for the systemic application of biomimetic design principles to mass communication technology. To supplement the purely system-level test, I conducted a series of interviews with interface-level designers regarding their own design strategies, generally accepted design strategies in the field of mass communication technology design, new design strategies, and the landscape of the field in general. The findings of my test lend strong credence to biomimicry's potential systemic contribution to mass communication technology design, and the tone of the interview …
