Nadzab (1943): The First Successful Airborne Operation, James Philip Lowe Jan 2004

Nadzab (1943): The First Successful Airborne Operation, James Philip Lowe

LSU Master's Theses

The U.S. Army in 1940 was in the early stages of developing an airborne capability to exploit the vertical envelopment concept. That concept became reality in 1942 with the first airborne operation in North Africa. Although the first parachute drop contributed virtually nothing to the overall success of the mission, it was the beginning of an important capability. In 1943, the War Department authorized five airborne divisions despite a lack of experience and doctrine to direct the new organizational structure. The airborne initiative expanded much more quickly than did the doctrine, training, or employment principles. The first attempts of conducting …

True Image, Janet K. Link Jan 2004

True Image, Janet K. Link

LSU Master's Theses

A still-life is often the painted record of a complex arrangement of objects. My aim in making the visual portion of TRUE IMAGE is to turn this sort of still-life inside out. Rather than arranging a collection of objects and making a painted or drawn image of the set up, I made simple images of things and arranged them with actual objects into three larger tableaux. The subjects of the paintings and drawings are these: checkerboards, objects, portraits, and shadows. The subjects of the tableaux are work (LABOR), home (DOMUS), and church (ECCLESIA). Viewed as a whole the exhibition asks …

Estimation Of Living Body Weight Based On Measurements Of Anterior Superior Iliac Spine Breadth And Stature, Jaime A. Suskewicz Jan 2004

Estimation Of Living Body Weight Based On Measurements Of Anterior Superior Iliac Spine Breadth And Stature, Jaime A. Suskewicz

LSU Master's Theses

Standard identification criteria for creating a decedent’s biological profile typically include ancestry, sex, age, and stature, but not body weight. Body weight information may not only assist in creating a more complete biological profile but may also provide insight into other forensic considerations, such as taphonomy and body transport and disposal. The current study seeks to establish multiple regression equations for the prediction of living body weight in skeletal remains. Specifically, the measurements of anterior superior iliac spine (ASIS) breadth and stature are assessed with regard to living weight. Research was carried out on both a skeletal sample and a …

Escalation Bias In Group Decision-Making, Molly Joann Russ Jan 2004

Escalation Bias In Group Decision-Making, Molly Joann Russ

LSU Master's Theses

The present study extended the literature on escalation bias to group decision-making in the context of performance appraisal. Escalation theory states that persons responsible for a hiring decision will provide higher evaluation ratings of that employee than those persons not responsible for the decision. This study compared the performance evaluation decisions of supervisors, individual team members, and teams in order to ascertain differences in escalation behaviors based on rater perspective and whether the rater was responsible for hiring the employee or not. Support for the hypotheses varied depending on the employment decision being made and the perspective of the decision-maker. …

Seismic Stratigraphic Investigation Of The Ukpokiti Field Channel Complex, Oml 108, Offshore Nigeria, Northwestern Niger Delta, Toby Latwan Stewart Jan 2004

Seismic Stratigraphic Investigation Of The Ukpokiti Field Channel Complex, Oml 108, Offshore Nigeria, Northwestern Niger Delta, Toby Latwan Stewart

LSU Master's Theses

Detailed seismic stratigraphic analyses and mapping show that a well defined Ukpokiti Field Channel complex (late Miocene) found on the up-thrown side of a major back-to-back fault system in the West Niger delta inner-continental shelf probably formed during a single eustatic fall. The channel (>500 msec, 10 km wide) shows several tributaries entering the trunk axis from what was probably a surface of subaerial exposure. Slumping is prominent on the north flank of the trunk channel. No channel unconformity is evident in the down-thrown block. This investigation seeks to resolve the lack of down-dip correlative seismic expression across the …

Innovative Cooling Configurations For Low Emission Gas Turbine Combustors, Ryan Thomas Hebert Jan 2004

Innovative Cooling Configurations For Low Emission Gas Turbine Combustors, Ryan Thomas Hebert

LSU Master's Theses

Presently, effective cooling of modern low NOx combustor liners is achieved through combinations of innovative impingement configurations and other heat transfer enhancement methods. An inherent characteristic of conventional impingement configurations is the occurrence of downstream heat transfer degradation due to increased crossflow effects. In the present study, two different impingement configurations are studied. Both impingement configurations examined in this study aim to increase heat transfer effectiveness by reducing the detrimental effects of spent air crossflow. In Part I, a combination technique wherein impingement is combined with ribs placed in between impingement rows is studied. Three configurations with increased rib placements …

A Re-Evaluation Of Geopressured-Geothermal Aquifers As An Energy Resource, Jeremy Scott Griggs Jan 2004

A Re-Evaluation Of Geopressured-Geothermal Aquifers As An Energy Resource, Jeremy Scott Griggs

LSU Master's Theses

The search for more efficient and economical forms of energy generation is a continual process. Natural gas production and electricity generation from geopressured-geothermal aquifers is an unconventional hydrocarbon source that has long been unproductive due to its marginal economics and lack of technological certainty. This thesis demonstrates that, based on modern technological competencies and economic constraints, geopressured-geothermal energy now maintains a viable future as an alternative domestic energy source.

Forum Selection In International Contract Litigation: The Role Of Judicial Discretion, Hannah Buxbaum Jan 2004

Forum Selection In International Contract Litigation: The Role Of Judicial Discretion, Hannah Buxbaum

Articles by Maurer Faculty

The United States is currently involved in negotiation of the Hague Convention on Exclusive Choice of Court Agreements, which would regulate the enforceability of forum-selection clauses in international contracts. That project - as well as the recent focus in globalization literature on more active judicial management of forum selection - draws attention to one unusual aspect of U.S. jurisdictional law: that dismissal on the basis of forum non conveniens is available even in cases arising out of contracts including negotiated forum selection clauses. This article examines the resulting tension between the right of contract parties to select a forum in …

Online Heat Transfer Measurement And Analysis For Sugar Mill Evaporators, David Timothy Solberg Jan 2004

Online Heat Transfer Measurement And Analysis For Sugar Mill Evaporators, David Timothy Solberg

LSU Master's Theses

Fouling and scaling in evaporators has been an area of great interest to raw sugar mills for a number of years and many of the mechanisms causing the scale and the rates of scaling are unknown. In an attempt to quantify the scaling rates and measure the scaling, an online model has been developed to model a system of evaporators. Monitoring the heat transfer coefficient as a function of time enabled measurement of the scaling rate by monitoring the heat transfer coefficient as it decreased with time. It is assumed that the scaling on the juice side of the evaporators …

The Sports Appeal: Are Atheletics A Viable Academic Marketing Vehicle In Higher Education?, Reagan Thomas Chenevert

LSU Master's Theses

Universities are beginning to brand themselves. The days when the doors to higher-ed opened and students flooded into the classrooms are no more. Colleges have to find ways to separate themselves from each other in a noisy marketplace. Also there is a decline in newsroom resources for academic coverage, which leaves university marketers searching for ways to communicate their messages. However, universities have another available marketing outlet, which is not seeing declining media attention: sports. College sports are a big business, which generate national media attention. The Southeastern Conference had revenues of over $100 million from the marketing of its …

Reliability And Concordance Of The Childhood Autism Rating Scale And Dsm-Iv In Adults With Severe And Profound Mental Retardation, Noha Farrah Minshawi Jan 2004

Reliability And Concordance Of The Childhood Autism Rating Scale And Dsm-Iv In Adults With Severe And Profound Mental Retardation, Noha Farrah Minshawi

LSU Master's Theses

Researchers and clinicians have long treated autism as though it were a disorder that only affected children. As a result, little literature is available on the diagnosis, assessment, and treatment of adults with autism. One of the first issues to address in this population is diagnosis. While several rating scales and diagnostic systems exist for surveying autistic behavior in children, researchers have not demonstrated the reliability of these scales for adults. The present study focused on two commonly used instruments, the Childhood Autism Rating Scale (CARS) and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). In the …

Bezier Curves For Metamodeling Of Simulation Output, Harish J. Kingre Jan 2004

Bezier Curves For Metamodeling Of Simulation Output, Harish J. Kingre

LSU Master's Theses

Many design optimization problems rely on simulation models to obtain feasible solutions. Even with substantial improvement in the computational capability of computers, the enormous cost of computation needed for simulation makes it impractical to rely on simulation models. The use of metamodels or surrogate approximations in place of actual simulation models makes analysis realistic by reducing computational burden. There are many popular metamodeling techniques such as Polynomial Regression, Multivariate Adaptive Regression Splines, Radial Basis Functions, Kriging and Artificial Neural Networks. This research proposes a new metamodeling technique that uses Bezier curves and patches. The Bezier curve method is based on …

Individual And Landscape-Level Effects Of Selective Herbicides, Mowing, And Prescribed Fire On Habitat Quality For Northern Bobwhite (Colinus Virginianus), Charles Lynn Kitts

LSU Master's Theses

Northern bobwhite (Colinus virginianus) populations have been declining throughout their range during the past 30 years primarily because of a result of loss of early successional habitat. Specifically, intensive silviculture practices and reduction in the use of prescribed fire has led to this loss. I studied effects of management practices (selective herbicides, mowing, and prescribed fire) on male and covey distribution, and brood-rearing habitats on Jackson-Bienville Wildlife Management Area (JBWMA). Specifically, I used calling surveys to assess landscape characteristics associated bobwhite distribution. I also measured vegetation and arthropod response, using imprinted bobwhite chicks, pitfalls, and sweep nets, to different habitat …

The Effects Of Non-Focused Extracorporeal Shock Waves On Neuronal Morphology, Function And Analgesia In Horses, David Manuel Bolt Jan 2004

The Effects Of Non-Focused Extracorporeal Shock Waves On Neuronal Morphology, Function And Analgesia In Horses, David Manuel Bolt

LSU Master's Theses

These studies were conducted to elucidate the regional analgesic effect that is observed clinically after treatment of orthopedic disorders with application of extracorporeal shock waves in horses. Regional analgesia after treatment with extracorporeal shock waves presents a concern because it may eliminate protective limiting mechanisms and may place equine athletes with predisposing lesions at risk of sustaining career- or life-ending injuries. Direct percutaneous application of non-focused extracorporeal shock waves to palmar digital nerves in the pastern area of horses resulted in decreased sensory nerve conduction velocities compared with untreated control nerves at 3, 7, and 35 days after treatment.
