Shear Strength Evaluation Of An Erosional Soil System At Fourchon Beach, Jacques Pierre Boudreaux Jan 2012

Shear Strength Evaluation Of An Erosional Soil System At Fourchon Beach, Jacques Pierre Boudreaux

LSU Master's Theses

South Louisiana is vanishing. Subsidence due to relative sea level rise with erosion of weak wetland soils together produce devastating rates of land loss for this area. It is believed that high rates of erosion are due to weak strength properties of fine-grained sediments in the beaches, marshes, and other wetlands in coastal Louisiana. Wave action is known to initiate the movement of weak coastal soils in a manner that is related to the difference between the shear stresses applied by waves and the critical shear strength of erosional sediments. Direct shear tests were performed on samples obtained from the …

Pmi 5011 Regulates The Ubiquitin Proteasome System In Skeletal Muscle, Heather Christianne Kirk-Ballard

LSU Doctoral Dissertations

Insulin resistance in type 2 diabetes is associated with impaired glucose and protein metabolism in skeletal muscle. The impaired insulin signaling in skeletal muscle affects muscle mass by tilting the balance between skeletal muscle protein synthesis and degradation toward degradation, a process that is primarily regulated by the ubiquitin-proteasome system. Studies have shown that an extensively characterized ethanol extract of Artemisia dracunculus L (Russian Tarragon), termed PMI 5011, enhances insulin signaling in human primary skeletal muscle cells and in a rodent model of insulin resistance. The aim of this project is to determine if the effect of PMI 5011 on …

Social Influences On Sculpted Romanesque Corbels In The Eleventh And Twelfth Centuries, Chelsea Buras Jan 2012

Social Influences On Sculpted Romanesque Corbels In The Eleventh And Twelfth Centuries, Chelsea Buras

LSU Master's Theses

Sculpted corbels of the Romanesque period are often categorized as obscene or grotesque, and frequently dismissed as medieval humor or an individual artist’s imagination. Common themes on corbels include images of debauchery and obscenity, as well as depictions of the effects of sin. These themes are usually communicated through the image of entertainers (acrobats, musicians, and dancers), acts of excess such as overindulgence in alcohol or sexual vice, threatening gestures, monstrous animals, or the human visage transformed by idiocy. As titillating and lowbrow as the images on corbels may seem, they should not be relegated to categories of absurdity or …

Comparing Symptoms Of Autism Spectrum Disorders Using The Current Dsm-Iv-Tr Diagnostic Criteria And The Proposed Dsm-V Diagnostic Criteria, Julie A. Worley

LSU Doctoral Dissertations

Children diagnosed with Autistic Disorder (AD), Asperger’s Disorder (AS), and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) share overlapping diagnostic criteria. As a result, there has been an enduring debate regarding the appropriateness of the current categorical classification system used to diagnose this group of disorders, commonly referred to as Autism Spectrum Disorders (ASD). Ongoing research examining the boundaries of the disorders comprising the spectrum have yielded inconsistent findings in symptom differences; therefore, the American Psychiatric Association has proposed revisions for the upcoming version of the Diagnostic and Statistical Manual of Mental Disorders (i.e., DSM-5). Revisions include dropping all subcategories …

Investigations At The Toncrey Site (16pl7): Analysis Of A Late Prehistoric Site In Extreme Southern Louisiana, Rebecca Muriel Brown

LSU Master's Theses

The Toncrey site (16PL07), located in the coastal marsh of Plaquemines Parish, Louisiana, is a prehistoric mound site containing three earthen mounds, on the north, west, and south edges of a plaza. The layout of the mounds in cardinal directions around the plaza suggests that this component of the site dates to the Coles Creek period. On the eastern side of the site an extensive, wave-washed and re-deposited oyster (Crassostrea virginica) shell midden contains diagnostic Coles Creek, Plaquemine, and Mississippian pottery. Archaeological research at the site was conducted to confirm the cultural affiliation of the mound group and midden, and …

Inside And Outside, Joshua Harry George Jan 2012

Inside And Outside, Joshua Harry George

LSU Master's Theses

The boxing paintings and drawings are not about fighting as much as they are about the fighter’s existence. Many of the images show the boxer training or in an isolated environment in order to show how methodical their lives become. I see boxers as sacrificial athletes, not only because their health is at risk, but also because they must separate themselves from loved ones during training, as well as abstain from certain foods in order to maintain a certain weight. Every boxer is an underdog, in a sense. They are all at risk of losing something, whether it is their …
