Variations In Pore Water Salinities Above And Below Allochthonous Salt Sheets In The Deepwater Gulf Of Mexico: Implications For Mechanisms Of Solute Transport, Miles Alexander Mccammon Jan 2012

Variations In Pore Water Salinities Above And Below Allochthonous Salt Sheets In The Deepwater Gulf Of Mexico: Implications For Mechanisms Of Solute Transport, Miles Alexander Mccammon

LSU Master's Theses

Spatial variations in salinity of pore waters in marine sediments provide useful information on processes and rates of subseafloor fluid flow and solute transport, particularly if there are evaporites in the section. Pore water salinities were determined for 18 drill holes which penetrated allochthonous salt bodies in 12 widely-scattered protraction blocks on the Louisiana offshore continental shelf and slope. Salinities were calculated from Log ASCII Standard-Logging While Drilling (LAS-LWD) logs using the Revil et al. (1998) dual-conductivity technique. The sites represent a wide range of field settings. Water depths range from 30 to 1990 m, depths to the top of …

Improving Middle School Math Achievement Using A Web-Based Program And Extended Written Tasks, Sarah Claire Dyer Jan 2012

Improving Middle School Math Achievement Using A Web-Based Program And Extended Written Tasks, Sarah Claire Dyer

LSU Master's Theses

This thesis outlines a dual-intensity approach using a web-based program, MyMathLab, for procedural fluency and, in parallel, extended written tasks for helping students improve their reasoning skills, to learn to use multiple representations, and securing mathematical knowledge. The new Common Core State Standards have increased expectations and achievement goals at all grade levels, the required changes being most significant at earlier grade levels (in elementary and middle schools). It is my assertion that a combined approach, one that encompasses both procedure-oriented practice for fluency and extended written tasks designed to stretch thinking and reasoning is needed to meet these goals.

Consumer And Processor Methods To Control Salmonella And Listeria In Shrimp, Genevieve Anne Edwards Jan 2012

Consumer And Processor Methods To Control Salmonella And Listeria In Shrimp, Genevieve Anne Edwards

LSU Master's Theses

A common method used by consumers to determine if shrimp are thoroughly cooked when boiling, is to wait until the shrimp float to the top of the water and are pink in color. The purpose of this study was to determine whether the current floating and color cooking method is adequate to ensure the elimination of Listeria and Salmonella species. Furthermore, to determine if processing and storage methods reduce the effectiveness of this method. Shrimp samples were submerged into bacterial suspensions for 30 min then allowed to air dry for 1 hr and color parameters were measured using a colorimeter. …

The Truth About Lying: The Memorial Effects Of Deliberately Producing Misinformation, Kathleen M. Vieira Jan 2012

The Truth About Lying: The Memorial Effects Of Deliberately Producing Misinformation, Kathleen M. Vieira

LSU Master's Theses

There are different ways of lying and these lies may have different impacts on memory. In this study, participants studied pictures of objects, and later lied and told the truth about these and other objects by describing them or by denying they had seen them. Forty-eight hours later, participants were tested on their source memory. Results revealed that participants had good memory for having falsely described a never-seen object, but poor memory for having falsely denied seeing a studied object. These results suggest that telling certain types of lies may make a person more likely to forget having lied at …

Air Quality At Bus Stops: Empirical Analysis Of Exposure To Particulate Matter At Bus Stop Shelters, Miguel Figliozzi, Adam Moore, Christopher Monsere Jan 2012

Air Quality At Bus Stops: Empirical Analysis Of Exposure To Particulate Matter At Bus Stop Shelters, Miguel Figliozzi, Adam Moore, Christopher Monsere

Civil and Environmental Engineering Faculty Publications and Presentations

Congested traffic corridors in dense urban areas are key contributors to the degradation of urban air quality. While waiting at bus stops, transit patrons may be exposed to greater amounts of vehicle-based pollution, including particulate matter (PM), because of their proximity to the roadway. Current guidelines for the location and the design of bus stops do not take into account air quality or exposure considerations. This study compared the exposure of transit riders waiting at three-sided bus stop shelters that either faced the roadway traffic or faced away from the roadway traffic. Shelters were instrumented with air quality monitoring equipment, …

Palynostratigraphy Of The Umir Formation, Middle Magdalena Valley Basin (Mmvb) Colombia, Carlos Enrique Santos Jan 2012

Palynostratigraphy Of The Umir Formation, Middle Magdalena Valley Basin (Mmvb) Colombia, Carlos Enrique Santos

LSU Master's Theses

The Late Cretaceous Umir Formation in Middle Magdalena Valley Basin (MMVB) was recently acknowledged as a new target. However, there is little known about the regional distribution of the Umir Formation since it is affected by structural complexity and a major regional unconformity. To improve biosteering of the Umir Formation and reduce exploratory risks, a detailed biostratigraphic analysis of the Umir Formation in the MMVB is presented. Eighty samples from four cores drilled in the Central Eastern MMVB were analyzed for palynological content. These cores represent 976.6 meters of the Middle to Upper Umir Formation. The sediment yielded a good …

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 …

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 …

Investigations At The Toncrey Site (16pl7): Analysis Of A Late Prehistoric Site In Extreme Southern Louisiana, Rebecca Muriel Brown Jan 2012

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 …

Reductive Dechlorination Of High Concentrations Of 1,2-Dichloroethane, 1,2-Dichloropropane, And 1,1,2-Trichloroethane By Dehalogenimonas Sp., Andrew D. Maness Jan 2012

Reductive Dechlorination Of High Concentrations Of 1,2-Dichloroethane, 1,2-Dichloropropane, And 1,1,2-Trichloroethane By Dehalogenimonas Sp., Andrew D. Maness

LSU Master's Theses

The research goals presented here were to evaluate the solvent concentrations over which Dehalogenimonas lykanthroporepellens strain BL-DC-9T and Dehalogenimonas sp. IP3-3 are able to reductively dechlorinate 1,2-dichloroethane (1,2-DCA), 1,2-dichloropropane (1,2-DCP), and 1,1,2-trichloroethane (1,1,2-TCA). Both of these novel bacteria were isolated from contaminated groundwater at the PetroProcessors of Louisiana, Inc. Superfund site located near Baton Rouge. Both cluster in the phylum Chloroflexi, related to, but distinct from, the widely studied, reductively dechlorinating “Dehalococcoides” strains .

Although previous research demonstrated that strains BL-DC-9T and IP3-3 are able to reductively dechlorinate a variety of polyhalogenated alkanes, the solvent concentration at which the strains …

Improving Nitrogen Management In Sugarcane Production Of The Mid-South Using Remote Sensing Technology, Joshua Lofton Jan 2012

Improving Nitrogen Management In Sugarcane Production Of The Mid-South Using Remote Sensing Technology, Joshua Lofton

LSU Doctoral Dissertations

In Louisiana, current N rate recommendations for sugarcane production are based on multiple year N response trials and refined based on soil and crop variables. Without accounting for current growing conditions, recommendations can potentially lead to over- or under-application of N. The objectives of this research were to 1) determine the ability of an in-season response index value (RINDVI) to estimate sugarcane yield response index (RIHarvest), 2) determine if sugarcane yield potential could be determined using normalized difference vegetative index (NDVI), and 3) estimate the optimum N rate and application timing for sugarcane production in Louisiana. Experiments were established in …

Turn-On's And Edible Friends: An Imaginal Menagerie, Matthew Ryan Henderson Jan 2012

Turn-On's And Edible Friends: An Imaginal Menagerie, Matthew Ryan Henderson

LSU Master's Theses

Turn-on’s and Edible Friends explores alternative sexual behavior. Societal standards have an overwhelming interest in imposing judgment upon sexual identity. The imagery is influenced by taboo and peculiar sexual fetishes. Animal personifications of the fetish are used as satire to detach the viewer from the action, and also as a metaphor for the reins with which the general public takes control over our private relationships. Thus the work becomes confrontational with the viewer and forces them to question their perceptions and comforts about sexual identity.
