Influence Of The Marsh Edge On The Structure And Trophic Ecology Of The Fish And Macroinvertebrate Community In A Louisiana Estuarine Ecosystem, Guillermo Duque Jan 2004

Influence Of The Marsh Edge On The Structure And Trophic Ecology Of The Fish And Macroinvertebrate Community In A Louisiana Estuarine Ecosystem, Guillermo Duque

LSU Doctoral Dissertations

Habitat degradation of saltmarsh ecosystems reduces the suitability of the marsh as permanent environments for resident species and seasonal nursery grounds for transient fauna. This study was conducted in Terrebonne-Timbalier bays near Cocodrie, Louisiana. Fishes and macroinvertebrates were collected using a drop sampler in marsh-edge and open-water habitat types, in three locations (i.e., pond, channel, and bay), and four seasons (Fall of 2000, Winter of 2000-2001, and Spring and Summer of 2001). The specific objectives of this study were: (1) to determine the difference in composition and structure of fish and macroinvertebrate communities, (2) to establish the food habits of …

Testing A Cmos Operational Amplifier Circuit Using A Combination Of Oscillation And Iddq Test Methods, Pavan K. Alli Jan 2004

Testing A Cmos Operational Amplifier Circuit Using A Combination Of Oscillation And Iddq Test Methods, Pavan K. Alli

LSU Master's Theses

This work presents a case study, which attempts to improve the fault diagnosis and testability of the oscillation testing methodology applied to a typical two-stage CMOS operational amplifier. The proposed test method takes the advantage of good fault coverage through the use of a simple oscillation based test technique, which needs no test signal generation and combines it with quiescent supply current (IDDQ) testing to provide a fault confirmation. A built in current sensor (BICS), which introduces insignificant performance degradation of the circuit-under-test (CUT), has been utilized to monitor the power supply quiescent current changes in the CUT. The testability …

Modeling The Hydrologic And Particulate Loadings From Paved Urban Surfaces, Chad Michael Cristina Jan 2004

Modeling The Hydrologic And Particulate Loadings From Paved Urban Surfaces, Chad Michael Cristina

LSU Doctoral Dissertations

This dissertation details the results of recent investigations concerning non-colloidal particulate matter found in urban rainfall-runoff and urban snowmelt. Three forms of the power law model (PLM) were used to model particle number density. It was found that significant model error could be introduced into PLMs when the median diameter particle was used to estimate the number of particles per interval, but the SSE of continuous PLMs could be significantly reduced through the use of correction factors when the sieve interval was large (P<0.05). Additionally, a multiple PLM analysis may be more appropriate than a single PLM analysis when changes in particle population occur within a single gradation. PLMs were also used to model the relationship between cumulative granulometric mass and cumulative particulate-bound metal mass. The use of such calibrated PLMs provided considerable cost reduction when compared to conventional direct measurements of particulate-bound metal mass. A first flush analysis indicated that only events with average volumetric flow rates approaching 1 L/min/m of drainage width exhibit a rapid depletion of particulate matter consistent with the concentration-based definition of the first flush. An analysis of particle separation mechanisms indicated that 90% of these particles, by mass, could be removed from the discharge with detention times of 30 min and 120 min for snowmelt and rainfall-runoff, respectively, in a typical roadside drainage system. It was also found that the kinematic wave model could accurately model significant aspects of rainfall-runoff events in traffic-impacted watersheds provided that abstractions were incorporated into the modeling process. For this watershed the source of abstraction was attributable to vehicular traffic. For high-intensity events with more than 10 vehicles per runoff volume (VPV) the runoff coefficient varied between 0.6 and 0.9 while for low-intensity events with fewer than 10 VPV the coefficient ranged between 0.2 and 0.4.

A Settlement Of Great Consequence: The Development Of The Natchez District, 1763-1860, Lee Davis Smith

LSU Master's Theses

This study examines events, conditions, and circumstances that influenced the development of the Natchez District of West Florida from its acquisition by Great Britain in 1763 until the eve of the Civil War. The strong relationships between West Florida and the “original thirteen” colonies created a dynamic area of Revolutionary and antebellum era growth in West Florida, and particularly in the Natchez District. Eighteenth century westward migration of seaboard colonists exerted pressure on native Americans. At the same time, colonists felt pressure from the presence of British troops remaining in America following the French and Indian War. Colonial officials recognized …

Volatiles Associated With Formosan Subterranean Termites And Related Methods Development, Paul Mclaughlin Jan 2004

Volatiles Associated With Formosan Subterranean Termites And Related Methods Development, Paul Mclaughlin

LSU Master's Theses

An investigation was conducted to identify volatiles associated with active Formosan termites. Using a combined technique of short path thermal desorption-gas chromatography/mass spectrometry (SPTD-GC/MS), qualitative comparisons were made between compounds detected in treatments containing active Formosan termites versus those detected in controls without Formosan termites. Except for dimethyl disulfide, none of the compounds were consistently detected in the treatments but not the controls for the four termite groups tested. However, in each of the three groups that dimethyl disulfide was detected, dead termites that were decomposing along with active termites were present. Therefore, none of the compounds could be classified …

The Figuration Of Caliban In The Constellation Of Postcolonial Theory, Paulus Sarwoto Jan 2004

The Figuration Of Caliban In The Constellation Of Postcolonial Theory, Paulus Sarwoto

LSU Master's Theses

The surrogation of Caliban from Shakespeare’s The Tempest to Césaire’s A Tempest has always been related to colonialism. In Shakespeare’s time, Caliban, depicted as half animal, served to represent the Other in an emerging colonial discourse. As opposed to Shakespeare’s character, Césaire’s Caliban is blatantly black and racially oppressed. Césaire indicates that A Tempest is an adaptation of Shakespeare’s The Tempest for black theater. As an adaptation, the play reinterprets the figure of Caliban to express postcolonial attitudes of the time. This thesis addresses the questions of how the figure of Caliban in Shakespeare’s play fits into the discourse of …

Multicolour Observations Of V404 Cyg With Ultracam, T. Shahbaz, V. S. Dhillon, T. R. Marsh, C. Zurita, C. A. Haswell, P. A. Charles, R. I. Hynes, J. Casares

Faculty Publications

We present high-time-resolution multicolour observations of the quiescent soft X-ray transient V404 Cyg obtained with ULTRACAM. Superimposed on the ellipsoidal modulation of the secondary star are large flares on time-scales of a few hours, as well as several distinct rapid flares on time-scales of tens of minutes. The rapid flares, most of which show further variability and unresolved peaks, cover shorter time-scales than those reported in previous observations. The power density spectrum of the 5-s time-resolution data shows a quasi-periodic oscillation (QPO) feature at 0.78 mHz (= 21.5 min). Assuming this periodicity represents the Keplerian period at the transition between …

Overexpression Of Gk In Gk-Transformed Cells Collapses The Golgi Apparatus Into The Endoplasmic Reticulum Inhibiting Virion Egress, Glycoprotein Transport, And Virus-Induced Cell Fusion, Timothy P. Foster, Galena V. Rybachuk, Xavier Alvarez, Olga Borkhsenious, Konstantin G. Kousoulas

Faculty Publications

Intracellular transport and egress of alphaherpesviruses require the coordinate function of multiple proteins and glycoproteins. Recently, we showed that gK is expressed on infected cell surfaces and that gK cell-surface expression required the presence of the UL20 protein [J. Virol. 77 (2003), 499]. Overexpression of gK by gK-transformed cells blocked transport of enveloped virions from perinuclear spaces and inhibited virus-induced cell fusion caused by gK syncytial mutants [J. Virol. 69 (1995), 5401]. Therefore, we investigated whether altered synthesis and transport of gK was responsible for the observed gK-mediated interference phenomena. HSV-1 infection of the gK-transformed cell line Vero (gK9) caused …

Agouti Expression In Human Adipose Tissue: Functional Consequences And Increased Expression In Type 2 Diabetes, Steven R. Smith, Barbara Gawronska-Kozak, Lenka Janderová, Taylor Nguyen, Angela Murrel, Jacqueline M. Stephens, Randall L. Mynatt

Faculty Publications

It is well recognized that the agouti/melanocortin system is an important regulator of body weight homeostasis. Given that agouti is expressed in human adipose tissue and that the ectopic expression of agouti in adipose tissue results in moderately obese mice, the link between agouti expression in human adipose tissue and obesity/type 2 diabetes was investigated. Although there was no apparent relationship between agouti mRNA levels and BMI, agouti mRNA levels were significantly elevated in subjects with type 2 diabetes. The regulation of agouti in cultured human adipocytes revealed that insulin did not regulate agouti mRNA, whereas dexamethasone treatment potently increased …
