The Introduction explains the study's purpose and explores the …

Fabrication Of A Microfluidic Platform For Impedance Analysis Of Cultured Endothelial Cell Monolayers., Stuart J. Williams 1981-

Electronic Theses and Dissertations

Assessing the functionality of the endothelium can provide insight into the initiation and formation of arterial diseases. One of the most important functions of the endothelial layer is its permeability. The integrity of the cell monolayer and its ability to transport molecules can be assessed in vitro by investigating the electrical impedance. In this study, a microfluidic platform was created using an electrode-patterned glass substrate and microfluidic poly(dimethyl siloxane) (PDMS) substrate. The electrode glass base of the structure was fabricated with platinum square electrodes of various sizes ranging from 10x10 ìm2 to 160x160 ìm2 and a larger, common counter electrode. …

A Local Model Of Writing Program Assessment : Fourteen Community College Faculty Define And Evaluate Writing Proficiency., Richard Anthony Butsch 1956-

Electronic Theses and Dissertations

The introduction to this doctoral dissertation is an argument for locating Writing Across the Curriculum programs on the community-college campus for several reasons, among them the proximity of the disciplines on the community college campus, the increasingly underprepared community college student, and movements toward accountability and assessment at the local and state levels. As an example of what a WAC program may accomplish in the area of program assessment, which developed from WAC proper in the last decade of the last century, Chapters One, Two and Three present data I collected from fourteen faculty volunteers who gave up a beautiful …

Origins Of Imperial Ottoman Architecture In Istanbul : A Cross-Cultural Interpretation On The Development Of A New Classical Tradition., Shannon P. Carneal

Electronic Theses and Dissertations

Following the conquest of Constantinople in 1453 by the Ottomans, a new trend in architecture developed that achieved a balance between the traditional Ottoman building practices of Bursa and Edirne with the styles found in Byzantium and the West. This thesis uncovers what led to the creation of a new Classical Ottoman architecture through an examination of the architectural resources available to the Ottoman sultans and their architects. The goal of this thesis is to discover what, if anything, is Ottoman about Ottoman imperial architecture in Istanbul. Was this new architecture the result of a logical progression of a traditional …

All-Boy Mathematics Classes In Middle School., Amanda Neel Davis

Electronic Theses and Dissertations

A comparative case study focused on six mathematics teachers of all-boy classes in three middle schools. Each school chose to experiment with gendered classes to improve specific, yet somewhat different, outcomes. A purpose of this study was not to compare single-gender schooling with coeducation, but rather, to focus on each school's implementation process and to identify school and classroom factors that seemed to contribute to success of the single-gender program. Another purpose was to examine mathematics teaching. Observational analysis used as a framework the Five Strands of Mathematics Proficiency. Related areas of inquiry were classroom time allocation, textbook selection and …

Novel Processes For Large Area Gallium Nitride Single Crystal And Nanowire Growth., Hongwei Li 1975-

Electronic Theses and Dissertations

III-nitrides (InN, GaN, AlN) are some of the most promising materials for making blue light emitting diodes (LED), blue laser diodes (LD) and high power, high temperature field effect transistors (FET). Current techniques produce GaN films with defect densities on the order of 107/cm2 or higher. The performance and life-time of the devices critically depend upon the defect densities and high power, high frequency devices require the defect densities to be lower than 104/cm2. So, the need for new processes to produce large size GaN crystals with defect densities less than 107/cm2 is immediate. In addition to large area single …

Comorbidity Of Attention Deficit Hyperactivity Disorder And Gender With Internalizing And Externalizing Symptoms., Anna Louise Peterson

Thermal Conductivity Measurement Of Thin Film Of Carbon Swnt Using The 3w Technique., Anton Nickolaevich Sidorov 1981-

Electronic Theses and Dissertations

We have measured the temperature-dependent thermal conductivity, K(T) of single walled carbon nanotubes from 300 K to 8 K by 3w methods. K(T) exhibits linear temperature dependence in the entire temperature range. Our results are in good agreement with the results obtained by Hone et al. using a standard steady state technique. Also we measured the temperature-dependent thermal conductivity K(T) of quartz and SiO2 in the same temperature range (300 K to 8 K) as a standardization tool. Our technique shows promise for the thermal conductivity measurements of many nanostructures with slight modifications.

Sex-Based Differences In Regulatory T Cells., Lum Doreen Nebane-Ambe 1975-

Electronic Theses and Dissertations

Females have a higher incidence of autoimmune diseases than males for reasons that are currently unknown. CD4+CD25+ regulatory T cells play an important role in the maintenance of immunological homeostasis and self-tolerance by suppressing autoreactive T cells that could potentially cause autoimmune diseases. Given that autoimmune diseases are more prevalent in women compared to men, we hypothesized that sex steroids could influence the incidence and/or progression of autoimmune disease through an effect on CD4+CD25+ regulatory T cell number and/or function. The overall objective of this project was then to determine whether sex steroids mediate sex-based differences in CD4+CD25+ regulatory T …

Ethnicity As An Independent Predictor Of Incontinence Care Seeking When Theoretical Modeling Is Used., Michael Heit 1962-

Electronic Theses and Dissertations

Urinary incontinence is a major public health problem affecting 30% of community dwelling women aged 35-85. Urinary incontinence may have a significant impact on activities of daily living depending on the severity of symptoms. Women with urinary incontinence suffer from psychological distress associated with the self-imposed social isolation required to hide their disorder from friends and family. The annual health care costs for managing urinary incontinence has been estimated at nearly 26 million dollars and 70% of these costs are attributed to remedies that are not covered by healthcare insurance. Yet, only 25-50% of incontinence sufferers seek professional care for …

Electronic Theses and Dissertations

This dissertation examines a research objective associated with human performance in agile production systems, with specific attention towards the hypothesis that system outcomes are the causal result of worker human cognition and quality of work life attributes experienced in an agile production system. The development and adoption of world class agile production systems has been an immediate economic answer to the world-wide competitive call for more efficient, more cost-effective, and more quality laden production processes, but has the human element of these processes been fully understood and optimized? Outstanding current literature suggests that the recent movements toward higher standards in …

Regionalism In The New Globalized Economy : Politics Of Scale And The Discourse Of Regionalism--Comparative Politics Of Two Japanese Global City-Regions., Takashi Tsukamoto

Electronic Theses and Dissertations

This study examines the effects of globalization on state restructuring and the status of cities and local governments. I conduct a comparative case study of two Japanese world cities, Tokyo and Osaka, Japan. Existing globalization theories offer only partial explanations that fail to grasp the dynamic aspects of such rescaling. To explore the dynamics of government restructuring, this study investigates the relationship between decentralization, regionalization and globalization, highlighting the role of local leaders who employed political rhetoric in their efforts to rescale the city. This research finds that uneven economic effects of globalization are not the direct cause for the …

New Families Of Voltage-Mode And Current-Mode Filter Circuits., Tongfeng Qian

Electronic Theses and Dissertations

In some previous papers, feed forward configurations of realizing second order all pass transfer functions with complex poles by adding some configurations to a first order circuit are discussed. In this dissertation, the above idea extended to realize some other basic second order complex pole filter transfer functions. A new corollary for circuit conversion is proposed and proved. This corollary is useful for converting op amp based voltage-mode circuits to their CCII based equivalent circuits, as are other existing theorems. But the new corollary is useful for converting circuits that cannot be converted by other theorems.

Optimization Of Process Parameters For Direct Metal Deposition Of Nickel., Steven James Gravatte

Electronic Theses and Dissertations

This research was performed to establish the feasibility of using Direct Metal Deposition (DMD) technology to deposit nickel powder to a nickel substrate. The substrate is electrodeposited pure nickel, and the material to be deposited is Metco 56C-NS Nickel powder which is 99.5% nickel and 0.5% trace elements. The DMD process is a form of laser welding; metallica powder is fed into and melted by a high power C02 later, which also melts the substrate. As the melted substrate and power re-crystallize, they form a metallurgical bond, as opposed to the mechanical bond created in a normal welding process. The …

An Ontological View Of The Kingdom Of God In Gutierrez, Segundo, Boff, And Sobrino, Hugo Monroy

Electronic Theses and Dissertations

The great majority of the four hundred and fifty million people in Latin America are poor and oppressed. Presenting the gospel to them as good news is a challenge for any theologian. Theologians' lives are at risk in most places regardless of the ideology they endorse. Jon Sobrino escaped death because he was lecturing out of the country when a military squad came into his home and killed his six companions and the two women who helped them. To serve in a context of poverty and death, theologians need more than church doctrines, creeds, and traditions to sustain them in …

The Text Of The Fourth Gospel In Greek Lectionary L1172, Timothy Neal Tutor

Evaluating The Effectiveness Of A Company's Online Health And Safety Training Program By Assessing Its Employees Perceptions And Knowledge., Jo Nell Maynard Mullins

Electronic Theses and Dissertations

A cross-sectional study was conducted to evaluate a company’s online H & S training program. The ABC Company’s online 8-hr HAZWOPER refresher course is based on current OSHA standard topics required for certification and principles flexible to fit site- or task-specific situations and conditions.

An 18-question survey was used to evaluate employee perceptions of online training compared to traditional classroom training. Perceptions were compared by demographic variables (e.g. gender, position, race, age and longevity with the ABC Company), which suggested that only age had an influence on employee response. Fifty-five percent of the employees surveyed preferred online training as compared …

The Myth Of The Lost Cause And Tennessee Textbooks, 1889-2002., Rachel Christine Duby

Electronic Theses and Dissertations

The Myth of the Lost Cause is an inaccurate account of the Civil War that remains prominent in American society. The myth alters key aspects of the war such as its cause, participants, and outcome. It is my hypothesis that one reason many Americans misunderstand the war is because they learned inaccurate information as children. Most children first learn of the war in school textbooks. I became curious as to the accuracy of Civil War information. As there is little research on this topic, this paper begins the process of bridging the gap between education curriculum and the Lost Cause. …

Trapped In Bluebeard's Chamber: Rose Terry Cooke And Nineteenth-Century "Desperate Housewives.", Bridget Renee Garland

Electronic Theses and Dissertations

Often overlooked in the study of nineteenth-century American literature, the New England writer Rose Terry Cooke elicited great popular appeal during the peak of her career. The admiration Cooke received from her readers and fellow writers compels one to question Cooke’s present-day obscurity. Cooke’s fiction and poetry seem inconsistent with the attitudes she express in her non-fiction, particularly concerning religion and women’s suffrage. She portrays women in miserable marriages, desperately looking for an escape. These “brides of Bluebeard” find different ways to cope with their predicament. While most never truly escape, many use (1) religious devotion, (2) masochism, and (3) …

A Limit Theorem In Cryptography., Kevin Lynch

Electronic Theses and Dissertations

Cryptography is the study of encryptying and decrypting messages and deciphering encrypted messages when the code is unknown. We consider Λ_π(Δx, Δy) which is a count of how many ways a permutation satisfies a certain property. According to Hawkes and O'Connor, the distribution of Λ_π(Δx, Δy) tends to a Poisson distribution with parameter ½ as m → ∞ for all Δx,Δy ∈ (Z/qZ)^m - 0. We give a proof of this theorem using the Stein-Chen method: As q^{m …}

Isolation, Purification, And Chemical Characterization Of The Dihydroxamate-Type Siderophore, "Schizokinen," Produced By Rhizobium Leguminosarum Iari 917., Erin P. Storey

Electronic Theses and Dissertations

Iron is essential to the majority of microorganisms; it is an important cofactor in many cellular processes and enzymes. However in an aerobic environment and at biological pH, iron is primarily found as insoluble oxyhydroxides and is unavailable to microorganisms. Many bacteria have the ability to produce siderophores, low molecular weight compounds that have a high affinity for Fe³⁺. Siderophores are part of a multi-component system that actively transports the iron-siderophore complex into the cytoplasm. Rhizobia are characterized by their ability to form symbiotic relationships with leguminous plants, where they can fix nitrogen for the host plant and …

The Tension Between Art And Science In Historical Writing., Michael Lee Depew

Electronic Theses and Dissertations

A perennial question in the philosophy of history is whether history is a science or an art. This thesis contests that this question constitutes a false dichotomy, limiting the discussion in such a way as to exclude other possibilities of understanding the nature of the historical task.

The speculative philosophies of Augustine, Kant, and Marx; the critical philosophies of Ranke, Comte along with the later positivist, and the historical idealist such as Collingwood will be surveyed. History is then examined along side art to discuss not only the similarities but, the differences.

Major similarities—narrative presentation, emplotation, and the selective nature …

Extensions Of The Cayley-Hamilton Theorem With Applications To Elliptic Operators And Frames., Alberto Mokak Teguia

Electronic Theses and Dissertations

The Cayley-Hamilton Theorem is an important result in the study of linear transformations over finite dimensional vector spaces. In this thesis, we show that the Cayley-Hamilton Theorem can be extended to self-adjoint trace-class operators and to closed self-adjoint operators with trace-class resolvent over a separable Hilbert space. Applications of these results include calculating operators resolvents and finding the inverse of a frame operator.
