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 …

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 …

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

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 …

Monitoring And Inverse Dispersion Modeling To Quantify Vocs From Msw Landfill, Sarit Kumar Das

LSU New Orleans Theses and Dissertations

In USA, the Municipal Solid Waste (MSW) landfills accumulate about 130 million tons of solid waste every year. A significant amount of biodegradable solid waste is converted to landfill gas due to anaerobic stabilization by bacteria. These biochemical reactions produce volatile organic compounds (VOCs) like methane and others. Due to heterogeneity in refuse composition, unpredictable distribution of favorable environmental conditions for bacterial actions and highly uncertain pathway of gases, estimation of landfill gas emission for a particular landfill is complex. However, it is important to quantify landfill gases for health risk assessment and energy recovery purposes. This research is based …

Enhancement Of The Properties Of Polymer By Using Carbon Nanotubes, Wai-Yin Tam

LSU New Orleans Theses and Dissertations

The outstanding properties of carbon nanotubes (CNTs) have stimulated a large number of researches to explore the potential of using them as reinforcement in polymer composites. Although many studies have reported the enlighten improvement of the materials properties by using CNTs as reinforcement, there are no promising and optimal results have been concluded to date. This thesis aims at studying the mechanical properties on thermoset polymer, Epoxy, by employing a small amount of carbon nanotubes as reinforcement. Two different types of nanotube-based composites are prepared i.e. a raw single-walled carbon nanotube (SWNT) composites and a functionalized single-walled carbon nanotube (FSWNT) …

Department of Animal Sciences Faculty Publications

Background

The chicken (Gallus gallus), like most avian species, has a very distinct karyotype consisting of many micro- and a few macrochromosomes. While it is known that recombination frequencies are much higher for micro- as compared to macrochromosomes, there is limited information on differences in linkage disequilibrium (LD) and haplotype diversity between these two classes of chromosomes. In this study, LD and haplotype diversity were systematically characterized in 371 birds from eight chicken populations (commercial lines, fancy breeds, and red jungle fowl) across macro- and microchromosomes. To this end we sampled four regions of ~1 cM each on …

Study Of Magnetization Switching For Mram Based Memory Technologies, Huy Pham

LSU New Orleans Theses and Dissertations

Understanding magnetization reversal is very important in designing high density and high data transfer rate recording media. This research has been motivated by interest in developing new nonvolatile data storage solutions as magnetic random access memories - MRAMs. This dissertation is intended to provide a theoretical analysis of static and dynamic magnetization switching of magnetic systems within the framework of critical curve (CC). Based on the time scale involved, a quasi-static or dynamic CC approach is used. The static magnetization switching can be elegantly described using the concept of critical curves. The critical curves of simple uncoupled films used in …

Examination Of Faculty Expectations Of Technical College Administrators As An Important Factor In High Performing Environments, Phyllis A. Dupuis

LSU New Orleans Theses and Dissertations

Popular thought supports the notion that faculty expectations of technical college administrators appear to be linked to the success or failure of an institution at accomplishing its mission. These expectations provide the basis for the development of relationships that foster the growth of technical training and thus the growth of a skilled workforce. Faculty members in technical colleges are responsible for training individuals to meet business and industry needs. Administrators are responsible for efficiently achieving the institution's mission of workforce development. Unknown faculty expectations may inhibit the ability of administrators to achieve the institution's mission in an efficient manner. This …

Homeplace Of Hands: Fractal Performativity Of Vulnerable Resistance, Diana L. Tigerlily

Dissertations

Homeplace of Hands: Fractal Performativity of Vulnerable Resistance is a feminist autoethnography of possibility that puts on display two new concepts I’ve named fractal performativity and vulnerable resistance. Fractal performativity as a way of seeing is an integrative performance methodology that utilizes fractal geometry and performative autoethnography and brings together performance studies, feminist theory, multiethnic literature, personal story and poetry to communicate vulnerable resistance as a strategy for social transformation and selfhood. Vulnerable resistance as a way of being embodies a praxis of homeplace enacted through five modes I’ve identified as nurturance, sustenance, maintenance, performance, and alliance, expressed through the …

A Qualitative Case Study Of Natural Storytelling Strategies Used At The Nantahala School., Nancy J. Reeder

Electronic Theses and Dissertations

This qualitative case study identifies what 8 teachers naturally do with storytelling at a K-12 school in western North Carolina. Through observations, interviews, field notes, document reviews, and artifact reviews, I used the constant comparison analysis method to discover themes from their formal and informal storytelling strategies. From these themes, I created a framework of 7 suggestions to enhance storytelling awareness. They are: sharing personal stories, developing voice control and body expression, connecting story to school culture, modeling well-developed stories with beginnings, middles, and ends, introducing stories with a pause, expressing the word "imagine" often during instruction, and finally, making …
