Mathematical Models For Estimating Volatile Chemical Emissions From Dredging Operations, Kenneth Alexander Fountain Jan 2005

Mathematical Models For Estimating Volatile Chemical Emissions From Dredging Operations, Kenneth Alexander Fountain

LSU Master's Theses

Dredging operations have been a common remediation for contaminated sediment in an effort to reduce the harmful impact on the environment. The objective of this research was to create models used for estimating chemical release to air from remediating the Indiana Harbor and Canal (IHC) as three separate dredging operations; the Dredge Site, Exposed DM CDF, and Ponded CDF. The evaporative flux estimations are based on a two-resistance mass transport path inclusive of both the molecular diffusion in porous media and interfacial airside mass transport resistances. Several chemodynamic algorithms were used in calculating key transport parameters. Laboratory tests were performed …

Sensorsimulator: Simulation Framework For Sensor Networks, Cariappa D. Mallanda

LSU Master's Theses

Wireless sensor networks have the potential to become significant subsystems of engineering applications. Before relegating important and safety-critical tasks to such subsystems, it is necessary to understand the dynamic behavior of these subsystems in simulation environments. There is an urgent need to develop a simulation platform that is useful to explore both the networking issues and the distributed computing aspects of wireless sensor networks. Current approaches to simulating wireless sensor networks largely focus on the networking issues. These approaches use well-known network simulation tools that are often difficult to extend to explore distributed computing issues. Discrete-event simulation is a trusted …

Vernacular Exposures At The Aillet House: Anthropological Interpretations Of Material Culture And Cultural Change, Kelli Ostrom Jan 2005

Vernacular Exposures At The Aillet House: Anthropological Interpretations Of Material Culture And Cultural Change, Kelli Ostrom

LSU Master's Theses

The thesis project developed from preliminary archaeological testing in 1999 at site 16WBR45, the original location of the Aillet House. The results of the testing were informative as they suggested the placement of the house and attested to casual activity on the porch. However, the results certainly did not answer the need for a more discerning interpretation of the historic house museum known as the Aillet House, currently on display at the West Baton Rouge Parish Museum. I collaborated with the museum in 2004 to bring to their current interpretive program anthropological insights gained from archaeological remains, an architectural survey …

Black Catholicism: Religion And Slavery In Antebellum Louisiana, Lori Renee Pastor Jan 2005

Black Catholicism: Religion And Slavery In Antebellum Louisiana, Lori Renee Pastor

LSU Master's Theses

The practice of Catholicism extended across racial boundaries in colonial Louisiana, and interracial worship continued to characterize the religious experience of Catholics throughout the antebellum period. French and Spanish missionaries baptized natives, settlers, and slaves, and the Catholic Church required Catholic planters to baptize and catechize their slaves. Most slaveholders outside New Orleans, however, were lax in the religious education of slaves. Work holidays did not always correspond to religious holy days, and the number of slave baptisms and confirmations on Catholic plantations often depended on the willingness of the local priest, or the slaves themselves, to attend the parish …

Thermal Management Of The Lsu Micro Gas Chromatograph, Praveen K. Pasupuleti Jan 2005

Thermal Management Of The Lsu Micro Gas Chromatograph, Praveen K. Pasupuleti

LSU Master's Theses

Gas chromatography is a technique widely used for the separation and analysis of gas samples. Gas chromatographs are used for environmental maintenance, monitoring sophisticated biological analyses, and to separate components from a mixture of gases for mass spectrometer analysis. There has been a tremendous interest in miniaturization of gas chromatograph systems because of the potential for portability, faster response time, lower dead volume, lower power consumption, and lower cost of operation. Conventional gas chromatography keeps the column at a constant temperature during separation, which is called isothermal analysis. Temperature programming is a mode of gas chromatography in which the column …

Molecular Dynamics Simulations Of Biological Membranes In The Presence Of Cryoprotectants, Dinesh Pinisetty Jan 2005

Molecular Dynamics Simulations Of Biological Membranes In The Presence Of Cryoprotectants, Dinesh Pinisetty

LSU Master's Theses

Cryopreservation is a process that is characterized by the transport of water and cryoprotectants through the cell membrane. This phenomenon has been studied in extensive detail at the macroscopic (µm) scale but in a somewhat more limited fashion at the microscopic (nm) scale. In this study we develop several lipid bilayer models to approximate a cell membrane (nm) and present the effect of several different cryoprotectants on the structural characteristics of these lipid bilayers using molecular dynamic simulations. The lipid bilayer models included dipalmitoylphosphatidylcholine (DPPC), dimyristoylphosphatidylcholine (DMPC) and palmitoyleylphosphatidylcholine (POPC) while the cryoprotectants included methanol and dimethylsulfoxide (DMSO). The molecular …

Ancient Maya Music Now With Sound, Cameron Hideo Bourg Jan 2005

Ancient Maya Music Now With Sound, Cameron Hideo Bourg

LSU Master's Theses

The subject of Maya music is by no means a new field of study for Hispanic cultural scholars or Mesoamerican anthropologists. For example, the archeological reports of Dr. Norman Hammond and Dr. Paul Healy have greatly increased the information in this area of study. The instrumentation utilized by ancient Maya musicians and the raw materials that were the essence of their production have been the major themes in these previous publications. However, these perspectives exclude the sound of music and aspects of ancient Maya society. This thesis has been planned to examine ancient Maya music according to archaeology, society and …

Dental Evidence For Division Of Labor Among The Prehistoric Ipiutak And Tigara Of Point Hope, Alaska, Felicia Madimenos Jan 2005

Dental Evidence For Division Of Labor Among The Prehistoric Ipiutak And Tigara Of Point Hope, Alaska, Felicia Madimenos

LSU Master's Theses

Among archaeological specimens, teeth can provide insight into the behaviors and cultural practices of a population. Inuit specimens are ideal for studying dentition because of the unique way teeth are used as tools. The prehistoric Ipiutak (ca.100 B.C. – A.D. 500) and Tigara (ca. A.D. 900 –1700) of Point Hope, Alaska, represent two environmentally similar, although culturally and temporally different, populations. Based on associated archaeological finds, the Ipiutak do not represent a whaling culture. Instead, they focused on hunting smaller sea mammals and caribou. Conversely, the Tigara represent a typical Inuit whaling culture. Whaling cultures depend on a distinct division …

The Influence Of Transdermally Administered Fentanyl On Isoflurane Requirements In Normothermic And Hypothermic Dogs, Diane Wilson Jan 2005

The Influence Of Transdermally Administered Fentanyl On Isoflurane Requirements In Normothermic And Hypothermic Dogs, Diane Wilson

LSU Master's Theses

Intraoperative reductions in serum fentanyl levels in dogs with induced moderate hypothermia and transdermal fentanyl patches (TDF) in place has been documented. The impact of such reductions has not been evaluated nor has the anesthetic sparing effect of the TDF. Reductions in serum levels may be the result of either a decreased uptake of fentanyl from the dermal depot, or a biophase shift. The objective of this investigation was to determine whether the minimum alveolar concentration (MAC) of isoflurane was altered in the presence of TDF in normothermic and hypothermic dogs. Six mature, healthy, mixed breed dogs were anesthetized on …

Evidence Of Neotectonic Activity In Southwest Louisiana, Jordan Oliver Heltz Jan 2005

Evidence Of Neotectonic Activity In Southwest Louisiana, Jordan Oliver Heltz

LSU Master's Theses

A methodology that combines high-resolution topographic mapping, field observations, subsurface evaluation, and geodetic data analysis has successfully located several fault-related geomorphic steps in an area of southwestern Louisiana once thought to be relatively devoid of such features. Comparison of height differences of benchmarks straddling these suspected fault-related steps shows that vertical displacement rates on faults in the study area ranged from about 2 mm/yr to as much as 6 mm/yr during the 1960’s and 1970’s. However, leveling data obtained as recently as January 2005 reveals that the majority of these faults are currently moving at rates of less than 1 …

The Everywhere Chronicles, Jamie Brownell Baldridge Jan 2005

The Everywhere Chronicles, Jamie Brownell Baldridge

LSU Master's Theses

The Everywhere Chronicles is a body of work that has been perambulating through my mind since the halcyon days of childhood. It is not intended as any sort of catharsis, metaphorical or otherwise, nor is it any forum of self discovery, accidental or intentional. These Chronicles are quite simply a journey into imagination, an exercise in "what ifs?". They confront the theory that Columbus was actually on a munchies run to an Indian Takeaway in Ipswich and simply took a wrong turn at the Antilles, and that the Lost City of Atlantis is alive and well somewhere outside of Duluth …

Physical Model Experiments Of The Gas-Assisted Gravity Drainage Process, Amit P. Sharma Jan 2005

Physical Model Experiments Of The Gas-Assisted Gravity Drainage Process, Amit P. Sharma

LSU Master's Theses

The displacement of oil by gas injection in oil reservoirs is an attractive method of improved oil recovery. Commercial gravity-stable gas injection projects have demonstrated excellent recoveries; however, their application has been limited to dipping reservoirs and pinnacle reefs. Horizontal gas floods and the water alternating gas (WAG) processes, practiced in horizontal type reservoirs, have yielded less than satisfactory recoveries of 5-10%. The Gas Assisted Gravity Drainage (GAGD) Process being developed at LSU extends the concept of gravity-stable gas floods to horizontal type reservoirs to improve volumetric sweep and oil recovery. This experimental study consists of a series of visual …
