Discrimination Of Cardiac Health And Disease By Assessment Of Heart Rate Variability: Wavelet Vs. Fast Fourier Transformation, Jusonda Leray Derouen Jan 2002

Discrimination Of Cardiac Health And Disease By Assessment Of Heart Rate Variability: Wavelet Vs. Fast Fourier Transformation, Jusonda Leray Derouen

LSU Master's Theses

The autonomic nervous system (ANS) modulation of the heart is of clinical importance because of its relevance to risk of life threatening arrhythmic events. Decomposition of heart rate variability (HRV) has been used to quantify ANS control of the heart. The traditional method for frequency analysis has involved the use of fast Fourier transformation (FFT). However, heart rate data typically violate assumptions of the FFT. Therefore, the assessment of HRV may benefit from other, potentially more suitable, mathematical approaches. For example, the discrete wavelet transformation (DWT) appears to have promise with respect to its ability to discriminate between healthy and …

The United States 1989 Military Intervention In Panama: A Just Cause?, William Harrision Huff Iv Jan 2002

The United States 1989 Military Intervention In Panama: A Just Cause?, William Harrision Huff Iv

LSU Master's Theses

American involvement in Panama dates back to 1903 when the United States helped bring independence to the Republic and soon after began construction of the Panama Canal. As the guarantor of Panamanian sovereignty, the U.S in the ensuing decades contributed to a non-democratic environment in Panama by supporting a series of dictators who promised stability in the region. The U.S. National Security policy just before Operation JUST CAUSE finally acknowledged the brutality of the Panamanian dictator, Manuel Noriega, forcing Washington to attempt numerous unsuccessful diplomatic maneuvers in an effort to avoid military intervention. Once combat operations commenced, the justification, necessity …

Endocrine And Reproductive Responses To Implants Of Deslorein Acetate In Horses, Carrie Ann Johnson Jan 2002

Endocrine And Reproductive Responses To Implants Of Deslorein Acetate In Horses, Carrie Ann Johnson

LSU Doctoral Dissertations

Four experiments were performed to study the effects of the gonadotropin releasing hormone (GnRH) analog, deslorelin acetate (Ovuplant™), on endocrine and reproductive characteristics in mares. The first experiment tested whether anecdotal field reports of Ovuplant causing extended interovulatory intervals would be detectable under controlled, experimental conditions. The use of Ovuplant to hasten ovulation in 13 mares, compared to 12 controls, increased (P < 0.05) the interovulatory interval by 6.2 d and suppressed (P < 0.05) plasma concentrations of both luteinizing hormone (LH) and follicle stimulating hormone (FSH) for approximately 11 d. Two mares receiving Ovuplant did not return to estrus within 30 d. In the second experiment, 10 control mares and 10 mares induced to ovulate with Ovuplant were administered GnRH (50 μg) on d 1, 4, 7, and 10 after ovulation. Again, treated mares had a longer (4.4 d, P < 0.05) interovulatory interval and suppressed LH and FSH concentrations in daily plasma samples. The gonadotropin response to GnRH was lower (P < 0.05) in the deslorelin mares on d 1, 4, and 7, indicating a lack of pituitary responsiveness. In the third experiment, 9 stallions and 12 steroid-treated geldings were used to determine if males were potential models for studying the deslorelin-induced gonadotropin suppression. In both cases, treatment with Ovuplant caused an initial rise in both gonadotropins followed by suppression for about 14 d. In the last experiment, 21 mares were used to determine if multiple doses of deslorelin would cause complete ovarian shutdown. Mares received either sham injections, three Ovuplant implants on the first day, or one implant per day for 3 d (n = 7 per group). Treatment with multiple deslorelin implants increased (P < 0.05) the interovulatory interval by 14.8 d and suppressed LH and FSH concentrations for approximately 25 d, however no mares exhibited complete ovarian shutdown. In conclusion, deslorelin acetate implants in horses in the form of Ovuplant induce short-term increases in LH and FSH secretion followed by long-term suppression of these concentrations and an insensitivity of the pituitary to GnRH. In a small percentage of mares, long-term ovarian shutdown is a possibility.

The Effects Of Local Hydrodynamics On Mass Transfer In Disordered Porous Media, Gang Guo

LSU Doctoral Dissertations

Interfacial mass transfer in disordered media was studied experimentally and numerically. The dissolution of solid benzoic acid spheres in packed columns showed the existence of spatial variations in mass transfer coefficients in monodisperse and polydisperse packings at the same overall Peclet number. The concept of a local Peclet number (single-particle average) was introduced to quantify the effect of local hydrodynamics on local mass transfer. Correlations between Sherwood number and Peclet number having the form Shi=A·(xiPe)m were used to quantify data from various sites in each packing. These experiments also showed that the exponent m varies …

Outcrop To Subsurface Stratigraphy Of The Pennsylvanian Hermosa Group Southern Paradox Basin U.S.A., Alan Lee Brown

LSU Doctoral Dissertations

Pennsylvanian (Desmoinesian) sedimentary rocks within the Paradox Basin Four Corners area of the western United States afford a unique opportunity to study the development of sedimentary successions in a complex marine to nonmarine depositional setting. The close association of thick intervals of nonmarine fan-delta facies adjacent to and in time equivalent position to marine carbonate-evaporite facies suggests complex relationships between the factors affecting deposition. Development of an effective scheme to differentiate the depositional signatures from within these sedimentary successions is the primary goal of this study. To achieve this goal, two objectives were pursued. The first was to calibrate the …

Qualitative Scoring Of The Rey 15-Item Memory Test In A Forensic Population, James A. Martin Jan 2002

Qualitative Scoring Of The Rey 15-Item Memory Test In A Forensic Population, James A. Martin

LSU Doctoral Dissertations

Several studies have examined the ability of the Rey 15-Item Memory Test (MFIT) to identify malingering of memory problems among a variety of psychiatric and neurologically impaired populations. The consensus has been that the quantitative scoring method is overly sensitive to genuine memory impairment and lacks sensitivity to simulated amnesia. However, a reexamination of these studies and available data indicates the MFIT is both valid and effective at identifying actual malingerers among civil litigants, and a number of these studies were limited through inappropriate inclusion of severely impaired patients and research designs of questionable validity. Also, the performance of a …
