Materials For Sustainable Constructions, Rosella Mafalda Ferraro Dec 2009

Materials For Sustainable Constructions, Rosella Mafalda Ferraro

Open Access Dissertations

White cement has currently received increasing attention due to potential for use in sustainable concrete structures. Based on the U.S. Green Building Council certification practice, the LEED Green Building Rating System for New Construction and Major Renovation (LEED-NC) considers that the reflective quality of white surfaces may help to improve lighting efficiency and reduce temperature fluctuations, resulting in lower heating and cooling with reduction of related energy costs. In addition to the environmental impact, white concrete represents a valuable tool for the aesthetic acceptability of a structure, and can also offer important practical benefits in terms of safety (i.e., light …

Behavior Of Full-Scale Reinforced Concrete Members With External Confinement Or Internal Composite Reinforcement Under Pure Axial Load, Antonio De Luca

Open Access Dissertations

The need to satisfy aerospace industry's demand not met by traditional materials motivated researchers and scientists to look for new solutions. The answer was found in developing new material systems by combining together two or more constituents. Composites, also known as fiber reinforced polymers (FRP) consisting of a reinforcing phase (fibers) embedded into a matrix (polymer), offered several advantages with respect to conventional materials. High specific modulus and strength together with other beneficial properties, corrosion resistance and transparency to electrical and magnetic fields above all, made FRP also suitable for use as construction materials in structural engineering. In the early …

Thermal Conduction In Molecular Materials Using Coarse Grain Dynamics: Role Of Mass Diffusion And Quantum Corrections For Molecular Dynamics Simulations, Ya Zhou, Alejandro Strachan Dec 2009

Thermal Conduction In Molecular Materials Using Coarse Grain Dynamics: Role Of Mass Diffusion And Quantum Corrections For Molecular Dynamics Simulations, Ya Zhou, Alejandro Strachan

PRISM: NNSA Center for Prediction of Reliability, Integrity and Survivability of Microsystems

We use a mesodynamical method, denoted dynamics with implicit degrees of freedom DID, to characterize thermal transport in a model molecular crystal below and above its melting temperature. DID represents groups of atoms molecules in this case using mesoparticles and the thermal role of the intramolecular degrees of freedom DoFs are described implicitly using their specific heat. We focus on the role of these intramolecular DoFs on thermal transport. We find that thermal conductivity is independent of intramolecular specific heat for solid samples and a linear relationship between the two quantities in liquid samples with the coefficient of proportionality being …

A measurement of the cross section for the inclusive production of isolated photons by the CDF experiment at the Fermilab Tevatron collider is presented. The measurement covers the pseudorapidity region |ηγ|<1.0 and the transverse energy range ETγ>30GeV and is based on 2.5fb-1 of integrated luminosity. The sample is almost a factor of 7 larger than those used for recent published results and extends the ETγ coverage by 100 GeV. The result agrees with next-to-leading order perturbative QCD calculations within uncertainties over the range 50

The Executive Pay Drama: From Comedy To Tragedy, David J. Cherrington Dec 2009

The Executive Pay Drama: From Comedy To Tragedy, David J. Cherrington

Faculty Publications

Over the past century, an interesting play has been performed in the United States called Executive Pay, Starring Your Local CEO. The play opened as a comedy, with executive bonuses and stock options rising at ridiculous rates compared to the pay of factory workers, teachers, and engineers. The performance didn’t get a lot of laughs, but people would smile and shake their heads as if the surprise of ever-escalating pay was an amusing disclosure. During economic downturns there were fewer smiles, and some outspoken critics were remarkably blunt in labeling executive pay practices as “enormous,” “immoral,” and “outrageous.” The title …

Thermal And Mechanical Multistate Folding Of Rnase H, Thomas A. Knotts, Terry J. Schmitt, Jonathan E. Clark Dec 2009

Thermal And Mechanical Multistate Folding Of Rnase H, Thomas A. Knotts, Terry J. Schmitt, Jonathan E. Clark

Faculty Publications

Two different classes of experimental techniques exist by which protein folding mechanisms are ascertained. The first class, of which circular dichroism is an example, probes thermally-induced folding. The second class, which includes atomic force microscopy and optical tweezers, measures mechanically-induced folding. In this article, we investigate if proteins fold/unfold via the same mechanisms both thermally and mechanically. We do so using Ribonuclease H, a protein that has been shown to fold through a three-state mechanism using both types of experimental techniques. A detailed, molecular-level description of the states involved in thermal and mechanical folding shows that mechanisms for both types …

Solid State And Solution Dynamics Of Pyridine Based Tetraaza- Macrocyclic Lanthanide Chelates Possessing Phosphonate Ligating Functionality (Ln-Pctmb): Effect On Relaxometry And Optical Properties, Garry Kiefer, Mark Woods

Chemistry Faculty Publications and Presentations

The macrocyclic ligand 3,6,9-tris(methylenebutyl phosphonic acid)-3,6,9−15-tetraazabicyclo [9.3.1]pentadeca-1(15),11,13-triene (PCTMB) was synthesized and complexes of Eu3+, Tb3+, and Gd3+ studied by X-ray crystallography, luminescence, and relaxometry. In the crystal these complexes are dimeric and possess 8-coordinate Ln3+ centers that are linked by bridging phosphonates. The rigidity introduced by the pyridyl nucleus forces the EuPCTMB and TbPCTMB to adopt a twisted snub disphenoid (TSD) coordination geometry. Examination of the 5D0 → 7F0 luminescent transition of EuPCTMB in the solid state confirmed the existence of a single distinct Eu3+ coordination environment, whereas two …

Electro-Disinfection Of Ballast Water, Elizabeth Kathleen Mccraven Dec 2009

Electro-Disinfection Of Ballast Water, Elizabeth Kathleen Mccraven

LSU New Orleans Theses and Dissertations

This research validates electro-disinfection as a potential secondary ballast water treatment technology. Electricity applied to bacteria laden water produced bactericidal effects, reactive oxygen species and chlorine generation which annihilated bacteria. Evaluation of electro-disinfection experiments showed titanium electrodes had the maximum kill efficacy while disinfection with aluminum and stainless steel electrodes had lesser kill efficacy. A continuous flow electro-disinfection reactor was evaluated utilizing artificial brackish and fresh ballast water. Brackish water had a 100% bacteria kill efficiency utilizing titanium electrodes at a current density of 10 mA/cm2. Fresh water was augmented with the addition of salt to increase its electrical conductivity …

A Bruised Sky Falling, Holly Dotson Dec 2009

A Bruised Sky Falling, Holly Dotson

LSU New Orleans Theses and Dissertations

The following thesis is a memoir in essays. The narrative is a reflection of memory as a chaotic system. Each essay stands alone as a single memory but also is part of the larger story of the writer's life. The fragmentation of the story lends itself to what Roland Barthes called a readerly text. That is, a reader may enter the text at any point and read the chapters in an order, and by doing this, the reader creates his/her own version of the author's life. The overall narrative arch is one of self-discovery and self-destruction.

Interactive Optimization Programs For Initial Propeller Design, Richard Biven Dec 2009

Interactive Optimization Programs For Initial Propeller Design, Richard Biven

LSU New Orleans Theses and Dissertations

This thesis presents two methods for initial design propeller optimization using constrained non- linear programming. The process uses the Nelder-Mead simplex algorithm. The Wageningen B-series optimal propeller selection is presented along with the combined annular momentum theory and blade element theory optimization. Both techniques require preliminary hull and engine design characteristics, but do not necessitate extensive background knowledge of pro- pellers and their calculations. A comparison of the two methods shows the combined annular momentum theory and blade element theory optimization produces the more e cient propeller. The optimization programs were designed with a graphic user interface implemented in the …

Comparative Analysis Of Marine Structural End Connections, Bret Silewicz Dec 2009

Comparative Analysis Of Marine Structural End Connections, Bret Silewicz

LSU New Orleans Theses and Dissertations

Numerous structural end connections are utilized everyday in the marine industry for ship design and/or maintenance. End connection design has been developed in earlier vessel designs and adapted as a general standard for all vessels being designed / built at a facility. Usually the supporting calculations developed to analyze the structural end connection are not available for engineers to re-examine. Furthermore, young engineers employ un-proven end connections in their designs, using the justification “It has been done like this in the past, it should work.” In this thesis, the author concentrates on finite element analysis for thirteen typical end connections …
