"Honduran Memories": Identity, Race, Place And Memory In New Orleans, Louisiana, Samantha Euraque Jan 2004

"Honduran Memories": Identity, Race, Place And Memory In New Orleans, Louisiana, Samantha Euraque

LSU Master's Theses

During the decade preceding the height of the civil rights movement, a small population of Hondurans established residence in the New Orleans area. This Honduran migration was largely due to the trade relationship that existed between Honduras and New Orleans. Honduras was also experiencing political unrest and economic instability due to military coups, fruit company strikes and floods during the late 1950s. In response, the advent of the 1960s brought with it the first wave of Hondurans. According to the 2000 Census there were 64,340 people of Hispanic origin in the four parishes included in the New Orleans metropolitan area, …

The Effects Of Reinforcement Magnitude On Functional Analysis Outcomes, Valerie Marie Volkert Jan 2004

The Effects Of Reinforcement Magnitude On Functional Analysis Outcomes, Valerie Marie Volkert

LSU Master's Theses

The functional analysis methodology developed by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994) has been successfully used to identify the variables that maintain the problem behavior of individuals with developmental disabilities. However, in some cases, the results of functional analysis may be inconclusive. Altering parameters of reinforcement, such as the schedule, the quality, or magnitude of the reinforcer, may increase the likelihood of obtaining clear functional analysis results. Few studies have evaluated the effects of reinforcement magnitude on problem behavior even though basic findings indicate that this parameter may alter functional analysis outcomes. In fact, reinforcement magnitude has varied widely …

Effects Of Aerobic And Anaerobic Training Protocols On 4000m Track Cycling Time Trial, William Mathieu Cheramie Jan 2004

Effects Of Aerobic And Anaerobic Training Protocols On 4000m Track Cycling Time Trial, William Mathieu Cheramie

LSU Master's Theses

The aim of this study was to determine whether performance in a 4000m individual pursuit could be significantly influenced by training protocols that are solely based in either aerobic/distance training, or anaerobic/sprint training. Faina et al., (1989) and Neuman et al. (1992) have found, using professional track cyclist that there appears to be a split in energy pathways used to perform the event. Their results indicate that 20% of the workload is achieved via anaerobic metabolism and the remaining 80% are achieved through aerobic metabolism. Group #1, followed a training protocol modeled after repeated, short duration, (<1:30.00s/1000m), high intensity sprinting. This particular training protocol may serve to utilize a greater proportion of its allotted time by generating beneficial metabolic adaptations that may possibly improve the subjects performance in the 4000m individual pursuit. Group #2, trained primarily through aerobic means, followed the "more traditional" training method for such an event. This protocol consisted of cycling intervals of distances proportionally longer (>4000m) than that …

Post Monitoring Of A Cyclodextrin Remediated Chlorinated Solvent Contaminated Aquifer, Rebecca Mary Hinrichs Jan 2004

Post Monitoring Of A Cyclodextrin Remediated Chlorinated Solvent Contaminated Aquifer, Rebecca Mary Hinrichs

LSU Master's Theses

Hydroxypropyl-β-cyclodextrin (HPβCD) has been tested successfully in the laboratory and in the field for enhanced flushing of low-polarity contaminants from aquifers. The cyclodextrin molecule forms a toroidal structure, which has a hydrophobic cavity. Within this cavity, organic compounds of appropriate shape and size can form inclusion complexes, which is the basis for the use of cyclodextrin in groundwater remediation. The hydrophilic exterior of the molecule makes cyclodextrin highly water-soluble. The solubility of cyclodextrins can be further enhanced by adding functional groups, such as hydroxypropyl groups, to the cyclodextrin core. The aqueous solubility of HPβCD exceeds 950 g/L. These high solubilities …

A Simplified Thermohydrodynamic Stability Analysis Of The Plain Cylindrical Hydrodynamic Journal Bearings, Sumit Singhal Jan 2004

A Simplified Thermohydrodynamic Stability Analysis Of The Plain Cylindrical Hydrodynamic Journal Bearings, Sumit Singhal

LSU Master's Theses

A journal bearing is used to support radial loads under high speed operating conditions. In a journal bearing, pressure or hydrodynamic lift is generated in the thin lubricant oil film that separates the shaft and the bushing, thus preventing metal-to-metal contact. Some journal-bearing configurations are susceptible to large-amplitude, lateral vibrations due to a “self-excited instability” known as oil whirl. In order to investigate the effects of lubricant viscosity on oil whirl, a simplified Thermohydrodynamic analysis (THD) analysis of a plain cylindrical journal bearing system has been developed. The “classical” form of the Reynolds equation coupled with simplified, first-order energy equations …

Effects Of Spinning-Wing Decoys On Flock Behavior And Hunting Vulnerability Of Local And Migrant Mallards And Other Ducks In Minnesota, Michael L. Szymanski

LSU Master's Theses

Waterfowl managers in Minnesota and other states are concerned that increased kill rates associated with the use of spinning-wing decoys (SWDs) may negatively affect local breeding populations of mallards (Anas platyrhynchos). I conducted 219 experimental hunts to evaluate hunting vulnerability of mallards to SWDs during the 2002 duck-hunting season in Minnesota. Following experimental hunts, I asked volunteer hunters to complete post-hunt questionnaires to document their hunting experience, and their use and opinions of SWDs. Finally, I used stable isotope methodology to determine natal origins of HY mallards killed during experimental hunts. I found that mallard flocks (≥1 duck) were 2.91 …

Address Optimizations For Embedded Processors, Sai Pinnepalli Jan 2004

Address Optimizations For Embedded Processors, Sai Pinnepalli

LSU Doctoral Dissertations

Embedded processors that are common in electronic devices perform a limited set of tasks compared to general-purpose processor systems. They have limited resources which have to be efficiently used. Optimal utilization of program memory needs a reduction in code size which can be achieved by eliminating unnecessary address computations i.e., generate optimal offset assignment that utilizes built-in addressing modes. Single offset assignment (SOA) solutions, used for processors with one address register; start with the access sequence of variables to determine the optimal assignment. This research uses the basic block to commutatively transform statements to alter the access sequence. Edges in …

Turbine Blade Tip Cooling And Heat Transfer, Hasan Nasir Jan 2004

Turbine Blade Tip Cooling And Heat Transfer, Hasan Nasir

LSU Doctoral Dissertations

Turbine blade tip leakage flow from blade pressure side to suction side over the tip surface increases the thermal loading to the blade tip, leading to a high local temperature and thus, is considered one of the primary sources of blade failure. Leakage flow can be reduced by using a recessed or squealer tip blade or by cooling the blade tip to incorporate film cooling. The performance of different recessed tip geometries were investigated and compared with plane tip performance. A transient liquid crystal technique was employed to measure detailed heat transfer coefficient distributions. Coolant injection from holes located on …

"Ya Know Frenchy, You Talk A Broken Language": An Analysis Of Syllable-Coda Phonetic Realizations In Creole African American Vernacular English, Rachel Rose Mentz Jan 2004

"Ya Know Frenchy, You Talk A Broken Language": An Analysis Of Syllable-Coda Phonetic Realizations In Creole African American Vernacular English, Rachel Rose Mentz

LSU Master's Theses

Creole African American Vernacular English or CAAVE is a variety of English spoken by African Americans of French ancestry who live primarily in the French Triangle of Louisiana. Dubois and Horvath (2003b) have previously published on glide absence in CAAVE and have suggested that CAAVE is a unique dialect of English. They attribute CAAVE’s glide absence to the contact of Creole African Americans with diverse groups of English speakers and not to language interference from French. This research further pursues these hypotheses by studying the phonological realization of word final syllable-codas for six old male speakers of CAAVE. The reduction …

The Effects Of Nutrient Enrichment On The Decomposition Of Belowground Organic Matter In A Sagittaria Lancifolia - Dominated Oligohaline Marsh, Kristen Raye Laursen Jan 2004

The Effects Of Nutrient Enrichment On The Decomposition Of Belowground Organic Matter In A Sagittaria Lancifolia - Dominated Oligohaline Marsh, Kristen Raye Laursen

LSU Master's Theses

Wetlands improve water quality through sedimentation and the uptake of excess nutrients. As human population increases in the coastal zone, wetlands receive greater nutrient inputs. These additional nutrients may accelerate microbial activity, leading to faster decomposition rates. This decomposition could exceed belowground organic matter production, resulting in a net reduction in soil organic matter accumulation and vertical marsh accretion. The effects of nutrient enrichment on belowground organic matter decomposition in subtropical marshes have received little attention. As such, this research examined the effects of four levels of nitrogen combined with two levels of phosphorus enrichment on belowground decomposition through the …
