Thickness Profiles Through Fatigued Bulk Ceramic Lead Zirconate Titanate, Nina Balke, Doru C. Lupascu, Thomas Blair Dec 2006

Thickness Profiles Through Fatigued Bulk Ceramic Lead Zirconate Titanate, Nina Balke, Doru C. Lupascu, Thomas Blair

Alexei Gruverman Publications

Wedge-cut samples of fatigued ferroelectric lead zirconate titanate ceramics were investigated using piezoresponse force microscopy in conjunction with conventional electrical hysteresis measurements. The local clamping of domains is monitored at different depths in the sample. The coercive fields in grains near the electrodes differ for different materials and preparation methods of the electrodes. For silver, fatigue consistently generates a space charge in the depth of the sample. For platinum electrodes, the fatigue behavior scatters strongly. Microscopically, it either occurs directly underneath the electrodes or resembles the behavior of the silver electrodes in other samples.

Structure Inhomogeneities, Shallow Defects, And Charge Transport In The Series Of Thermoelectric Materials K2bi8−Xsbxse13, Jeffrey S. Dyck, T. Kyratski, E. Hatzikraniotis, K. M. Paraskevopoulos, C. D. Malliakas, C. Uher, M. G. Kanatzidis

Physics

The charge transport properties of the low-dimensional thermoelectric materials K2Bi8-xSbxSe13 (02Bi8-xSbxSe13 was analyzed on the basis of the classical semiconductor theory and discussed in the context of recent band calculations. The results suggest that the K2Bi8-xSbxSe13 materials possess coexisting domains with semimetallic and semiconducting characters whose ratio is influenced by the value of x and by local defects. The extent and relative distribution of these domains control the charge transport properties. Electron diffraction experiments performed on samples of K2 …

Advancing The Methodology For Cyclopenta[C]Thiophene Sythesis: A Step Toward Anit-Leukemia Agents And Improved Semiconductiors, Riley Jones Dec 2006

Advancing The Methodology For Cyclopenta[C]Thiophene Sythesis: A Step Toward Anit-Leukemia Agents And Improved Semiconductiors, Riley Jones

Mahurin Honors College Capstone Experience/Thesis Projects

Metal n5-cyclopenta[c]thienyl complexes are of significant interest in both catalysis and materials chemistry. These relatives of the low-band-gap polymer polybenzo[2,3-c]thiophene show great promise as environmentally stable conductive polymers and as energy-efficient light-emitting diodes (LEDs) due to their unique electronic properties. Recently, studies have shown that cyclopenta[c]thiophene molecules are effective as photodynamic anticancer agents which are particularly aggressive toward leukemia cells. The current method of synthesizing these compounds is lengthy, costly, and has a very low yield. Our group has developed a novel one-step method to produce precursors of these compounds. This procedure increases product yields, eliminates the use of toxic …

Responses Of Pond-Breeding Amphibians To Wildfire: Short-Term Patterns In Occupancy And Colonization, Blake R. Hossack, Paul Stephen Corn Dec 2006

Responses Of Pond-Breeding Amphibians To Wildfire: Short-Term Patterns In Occupancy And Colonization, Blake R. Hossack, Paul Stephen Corn

United States Geological Survey: Staff Publications

Wildland fires are expected to become more frequent and severe in many ecosystems, potentially posing a threat to many sensitive species. We evaluated the effects of a large, stand-replacement wildfire on three species of pond-breeding amphibians by estimating changes in occupancy of breeding sites during the three years before and after the fire burned 42 of 83 previously surveyed wetlands. Annual occupancy and colonization for each species was estimated using recently developed models that incorporate detection probabilities to provide unbiased parameter estimates. We did not find negative effects of the fire on the occupancy or colonization rates of the long-toed …

Legitimacy As An Assessment Of Existing Legal Standards: The Case Of The 2003 Iraq War, Charlotte Ku Dec 2006

Legitimacy As An Assessment Of Existing Legal Standards: The Case Of The 2003 Iraq War, Charlotte Ku

Faculty Scholarship

The Iraq war was a multiple assault on the foundations and rules of the existing UN-centered world order. It called into question the adequacy of the existing institutions for articulating global norms and enforcing compliance with the demands of the international community. It highlighted also the unwillingness of some key countries to wait until definitive proof before acting to meet the danger of the world's most destructive weapons falling into the hands of the world's most dangerous regimes. It was simultaneously a test of the UN's willingness and ability to deal with brutal dictatorships and a searching scrutiny of the …

A Case Study Of Inter-Arrival Time Distributions Of Container Ships, Tu-Cheng Kuo, Wen-Chih Huang, Sheng-Chieh Wu, Pei-Lun Cheng Dec 2006

A Case Study Of Inter-Arrival Time Distributions Of Container Ships, Tu-Cheng Kuo, Wen-Chih Huang, Sheng-Chieh Wu, Pei-Lun Cheng

Journal of Marine Science and Technology–Taiwan

Given the recent prevalence of periodical container liners, the applicability of related models of widely applied queuing theory is left in doubt. Since they focus on marine liners, the distribution pattern is always considered to be a deterministic distribution for periodical schedule. In order to investigate the distribution patterns of container liners, observation units are segmented into single shipping liners, single berths, single container terminals and entire ports. The evolution of the ship arrival distribution pattern and the goodness-of-fit test for observation are based on the ship dynamic data of international harbors in Taiwan. This study aims to implement tests …

Angle Resolved Photoemission Study Of Epitaxial Chromium Dioxide Films, Daniel Borst Dec 2006

Angle Resolved Photoemission Study Of Epitaxial Chromium Dioxide Films, Daniel Borst

LSU New Orleans Theses and Dissertations

Chromium dioxide is predicted to be a half-metallic oxide. The electronic properties of the surface region of CrO2 have been studied by performing angle-resolved ultra-violet photoelectron spectroscopy (ARUPS) measurements on epitaxial CrO2 films. The CrO2 thin films were deposited on (100) and (110) – oriented TiO2 substrates by chemical vapor deposition. Previous measurements of the transport properties of devices made from epitaxial CrO2 films have shown very little spin polarization. Possible sources of this low yield are a surface Cr2O3 phase and/or surface contamination. The effects of sputtering the CrO2 films to remove the outer layer of Cr2O3 and any …

Becoming And Un-Becoming, Monica Zeringue Dec 2006

Becoming And Un-Becoming, Monica Zeringue

LSU New Orleans Theses and Dissertations

My work is about becoming and un-becoming. I seek to capture a time of transition and possibility. The pre-pubescent girls in my drawings are actually reduced versions of me, going back to a time of innocence and potential, and I multiply them as a means of selfexploration. They split apart, re-combine, and re-configure, trying to make a new whole. They are rendered with detailed accuracy, yet the world around them is empty, like a partially recalled memory. In this thesis, I will explore the use of the self-portrait, twinning, and re-configuration as they relate to identity, memory, and nostalgia. I …

An Empirical Analysis Of Commercial Bank Profitability In Financially Liberalized Markets, James Nguyen Dec 2006

An Empirical Analysis Of Commercial Bank Profitability In Financially Liberalized Markets, James Nguyen

LSU New Orleans Theses and Dissertations

Chapter 1 of the dissertation investigates the determinants of bank interest margin (NIM) and noninterest income (NII) using a system estimation approach for all commercial banks in a group of 28 financially liberalized countries during the period between 1997 and 2004. The empirical results generally suggest that NIM is directly influenced by operating costs, risk aversion, credit risk, the interaction between interest rate risk and bank risk, bank size, volume of credit, and NII. NIM is negatively related to interest rate risk and capital adequacy. NII is found to correlate positively with NIM, total assets, credit risk, liquidity risk, overhead …

Land Loss: Attachment, Place And Identity In Coastal Louisiana, David Burley Dec 2006

Land Loss: Attachment, Place And Identity In Coastal Louisiana, David Burley

LSU New Orleans Theses and Dissertations

This dissertation explores how people frame environmental change. Specifically, this work explores the identity loss that residents of coastal Louisiana experience due to coastal land loss. I rely on 126 in-depth interviews of residents from communities in six coastal parishes (counties). Respondents convey the meanings they give to land loss through constructing a narrative of place. A phenomenological approach is employed that focuses on how stories are told and the subjective interpretations of societal members. First, Louisiana's coastal communities hold a significant attachment to place that in many cases has been developing for close to three centuries. For most residents, …

A Parallel Architecture For Analog-To-Digital Conversion With Improved Dynamic Range, Brandy Sausse Dec 2006

A Parallel Architecture For Analog-To-Digital Conversion With Improved Dynamic Range, Brandy Sausse

LSU New Orleans Theses and Dissertations

In this thesis, a parallel architecture for Analog-to-Digital Converters (ADCs) is developed to increase the system dynamic range. The proposed architecture is a critical component for a Continuous Wave Stepped Frequency (CWSF) radar system. Existing Commercial Off-The-Shelf (COTS) components are inadequate to meet the demands of a high sample rate and a high dynamic range specification. The proposed parallel architecture meets the design criteria by extending the upper voltage limit of high sample rate converters. Extensive simulation study verifies that the desired high sample rate and increased resolution is achieved.

Emergence Of Attached Recirculating Eddy For Flow Around A Circular Cylinder Asymmetrically Placed In A Channel, Tsung-Chan Hsieh, Jiahn-Horng Chen Dec 2006

Emergence Of Attached Recirculating Eddy For Flow Around A Circular Cylinder Asymmetrically Placed In A Channel, Tsung-Chan Hsieh, Jiahn-Horng Chen

Journal of Marine Science and Technology–Taiwan

This study discusses the emergence and development of cylinder-attached recirculating regions appearing in a fully developed flow past a circular cylinder asymmetrically confined between two infinite parallel plates. We employed a finite-volume method with the SIMPLE algorithm to compute the flow fields for various sizes and asymmetrical settings of circular cylinders. Two geometrical parameters, the blockage and asymmetry coefficients, are varied in computations. A series of computations show that the flow evolves a single asymmetrical recirculating region for the Reynolds number beyond some critical value. Its development in length bears a linear relation to the Reynolds number. Its growth rate …

Successful Transitions Of Runaway/Homeless Youth From Shelter Care, Von Eugene Nebbitt, Laura E. House, Sanna J. Thompson, David E. Pollio

Social Work Faculty Publications

Previous research indicates that runaway and homeless youth often achieve positive outcomes after shelter stays however few studies have examined how these outcomes are achieved. This study employs qualitative methods to explicate this phenomenon. Twenty-five providers and 21 youth from four shelters participated in this study. Youth were recruited who had completed shelter care and returned home for minimally six months. Multiple raters identified themes and created a conceptual model. While in shelter, youths experienced structure and freedom, and the family experienced respite. Once youth became involved in treatment, the family re-connected and the youth returned home. After returning home, …
