An efficient integral equation method based on a method of moment (MoM) discretization of the Mixed-Potential Integral Equation (MPIE) for the analysis of 2.5D or 3D planar microwave circuits is presented. The robust Discrete Complex Image Method (DCIM) is employed to approximate the Greens functions in layered media for horizontal and vertical sources of fields, where closed-form formulations of the z-integrations are derived in the spectral domain. Meanwhile, an efficient and accurate numerical integration technique based on the Khayat-Wilton transform is used to integrate functions with 1/R singularities and near singularities. The fast iterative solver - Quadrature Sampled Pre-Corrected Fast …

Mediating Indigenous Identity: Video, Advocacy, And Knowledge In Oaxaca, Mexico, Laurel Catherine Smith

University of Kentucky Doctoral Dissertations

In the southern Mexican state of Oaxaca, many indigenous communities further their struggles for greater political and cultural autonomy by working with transnational non-governmental organizations (NGOs). Communication technology (what I call comtech) is increasingly vital to these intersecting socio-spatial relations of activism and advocacy. In this dissertation, I examine how comtech offer indigenous individuals and organizations with the means for visualizing their political-cultural agendas. Approaching the access and use of comtech, especially video technologies, as a partial and situated technoscience, I inquire into how and why these activities reconfigure the production and evaluation of authoritative knowledge about indigenous peoples, places, …

Identity In Evangelical Ukraine: Negotiating Regionalism, Nationalism, And Transnationalism, Esther Grace Long

University of Kentucky Doctoral Dissertations

This dissertation examines identity formation among evangelical Protestants in contemporary Ukraine. The overarching question is this: how do Ukrainian evangelicals view themselves and their churches in the context of Ukrainian regionalism, Ukrainian nationalism, and religious transnationalism? This question demands a closer look at Ukrainian regional variation, the status of Ukrainian national identity among evangelical practitioners, and the process of religious transnationalism, including how evangelicals perceive the West. This project is primarily based on qualitative research methods carried out over a ten month period. Field methods included participant observation, focus group interviews, and individual interviews. A set of maps produced by …

The Promise Of Internet Intermediary Liability, Ronald J. Mann, Seth R. Belzley

Faculty Scholarship

The Internet has transformed the economics of communication, creating a spirited debate about the proper role of federal, state, and international governments in regulating conduct related to the Internet. Many argue that Internet communications should be entirely self-regulated because such communications cannot or should not be the subject of government regulation. The advocates of that approach would prefer a no-regulation zone around Internet communications, based largely on the unexamined view that Internet activity is fundamentally different in a way that justifies broad regulatory exemption. At the same time, some kinds of activity that the Internet facilitates undisputedly violate widely shared …

Justice And Fairness In The Protection Of Crime Victims, George P. Fletcher

Faculty Scholarship

In this Article, Professor Fletcher discusses the crucial distinction between justice and fairness-as well as its effect on the shifting "boundaries of victimhood "-from a comparative viewpoint by examining the approaches that various human rights instruments take to the problem of victims' rights. While the European Convention on Human Rights represents an evolving "middle ground" in the treatment of victims' rights (such recent cases as X. & Y. v. The Netherlands, A. v. United Kingdom, and M.C. v. Bulgaria are examined), only the Rome Statute of the International Criminal Court gives real priority to victims of crime with …

Using Sequential Imagery To Evaluate Aspects Of Seed Vigor And Germination, Manjul Dutt

University of Kentucky Master's Theses

A sequential imaging system using a flat bed scanner interfaced to a personal computer was developed to study seed germination and vigor. The utility of the system was demonstrated in studies relating aspects of seed vigor in impatiens seed lots and for dormancy release in two woody perennials. Impatiens seed lots were kept in storage for 6 months to obtain a range in vigor levels. The ability to see differences at the individual seed level was possible because of the development of the sequential imaging system. It was observed that seeds deteriorated both under optimum 4OC as well as 25OC …

The Use Of A Whole Genome Scan To Find A Genetic Marker For Degenerative Suspensory Ligament Desmitis In The Peruvian Paso Horse, Diane I. Strong

University of Kentucky Master's Theses

Degenerative suspensory ligament desmitis (DSLD) is a debilitating disease of connective tissues seen in many breeds but has become prevalent in the Peruvian Pasohorse. DSLD is believed to be a genetic disorder caused by one primary founder and most likely has a recessive mode of inheritance although a dominant or co-dominant mode of inheritance has not been ruled out.

A genome scan using 259 microsatellite markers was used to test for linkage disequilibrium between one or more markers and DSLD. Two groups of Peruvian Pasohorses were selected from one population including the US and Canada. The only difference between the …

The main purpose of an RPS is to foster the development of renewable energy market, increase the energy security by reducing the dependence on the imported energy sources (oil, etc.), and, to provide environmental benefits from using more renewable energy. There are different approaches to the design and implementation of RPS in different states in U.S. and the degree of achieving a success of the policy differs also, …

An Historical Retrospective On The Origin Of And Changes To The Worker's Compensation Insurance Industry, Gary Eure

Theses

Workers' compensation insurance companies have been at the vanguard of workplace safety initiatives maintaining laboratories, training facilities, intern programs, and hierarchical structures. Up until the late 1980's, risk control services were provided to clients as a customer service, with the costs hidden in the premiums. Many companies estimated 4-5 percent of the premium amount was devoted to risk control departments. The late 1980s brought about a change that some attribute to a misapplication of Deming's Total Quality Management (TQM) philosophy. Insurance companies tried to make the move to accountability, thinking that it would drive customer service to a "Deming" level …

Integration Of Micromachined Thermal Thermal Shear Stress Sensors With Microchannels - Design, Fabrication And Testing, Vinod Dilip Kulkarni

Theses

Rochester Institute of Technology, 2005 Includes bibliographical references (leaves 91-96) "The emerging picture of microvascular flow strongly suggests that local gradients in shear rate along the arteriole walls play an integral role in the ability of a microvascular network to regulate and modify blood flow. The methods to estimate shear stress from approximations of the velocity profiles determined by in vivo particle tracking experiments in the hamster and computational simulation are limited by assumptions made about the flow and experimental techniques. Right now, our ability to relate wall shear stress in microvessels to corresponding biological function is limited by our …

Cfd Modeling Of Heat Recovery Steam Generator And Its Components Using Fluent, Veera Venkata Sunil Kumar Vytla

University of Kentucky Master's Theses

Combined Cycle power plants have recently become a serious alternative for standard coal- and oil-fired power plants because of their high thermal efficiency, environmentally friendly operation, and short time to construct. The combined cycle plant is an integration of the gas turbine and the steam turbine, combining many of the advantages of both thermodynamic cycles using a single fuel. By recovering the heat energy in the gas turbine exhaust and using it to generate steam, the combined cycle leverages the conversion of the fuel energy at a very high efficiency. The heat recovery steam generator forms the backbone of combined …

The Intersection Of Filial Piety And Cultural Dissonance: Intergenerational Exchanges Among Khmer Families In The United States, Denise Clark Lewis

University of Kentucky Doctoral Dissertations

In this thesis I describe Khmers negotiations of circumstances surrounding the disassembly, reconstruction, and redefinition of Khmer identity from their homeland in Cambodia to a traditional Khmer village recreated in the United States. Using a framework derived from a constructivist perspective, I have placed processes of negotiation and identity transformation within the lived context of Khmers lives. Thus, a holistic understanding of the interrelatedness of multiple changes in Khmerness is made possible. Ethnographic data collected between 1997 and 1999, through participant-observation and interviews, inform this study. Findings from this study reveal three levels of identity transformation as told by members …

High-Temperature Fluorescent In Situ Hybridization For Detecting Escherichia Coli In Seawater Samples, Using Rrna-Targeted Oligonucleotide Probes And Flow Cytometry, Ying Zhong Tang, Karina Yew Hoong Gin, Tok Hoon Lim

OES Faculty Publications

Fluorescence in situ hybridization (FISH) is a widely used method to detect environmental microorganisms. The standard protocol is typically conducted at a temperature of 46°C and a hybridization time of 2 or 3 h, using the fluorescence signal intensity as the sole parameter to evaluate the performance of FISH. This paper reports our results for optimizing the conditions of FISH using rRNA-targeted oligonucleotide probes and flow cytometry and the application of these protocols to the detection of Escherichia coli in seawater spiked with E. coli culture. We obtained two types of optimized protocols for FISH, which showed rapid results with …

OES Faculty Publications

With the use of continuous culture systems, rates of dinitrogen (N₂) and carbon (C) fixation and nitrogen (N)- and C-based doubling times were assessed in Trichodesmium IMS101 growing exponentially at steady state dilution rates of 0.10, 0.20, and 0.33 d^-1 (doubling times of 10, 5, and 3 d - within the range reported for natural populations). Rates of C fixation, N₂ fixation, and N release were examined in replicate culture systems with several techniques. Biomass-specific C uptake varied little with population doubling time, but N₂ fixation and N release varied markedly among treatments. Total daily …

Do Viruses Affect Fecundity And Survival Of The Copepod Acartia Tonsa Dana?, Lisa A. Drake, Fred C. Dobbs

OES Faculty Publications

Naturally occurring viruses are extremely abundant in aquatic systems, and they infect bacteria, cyanobacteria, prokaryotic and eukaryotic phytoplankton, heterotrophic nanoflagellates, fish and mammals. Viral infections of single-celled organisms have been studied intensively in the past decade, but little is known about the effects of viruses on aquatic metazoans, other than for some economically important species. Because zooplankton assemblages are often dominated in number and biomass by copepods, we used them as model organisms to study the effects of naturally occurring viruses on higher trophic levels. We attempted to induce viral infection in laboratory-reared cultures of the estuarine copepod Acartia tonsa …

Built-In-Self-Test Of Rf Front-End Circuitry, Anand Gopalan

Theses

Fuelled by the ever increasing demand for wireless products and the advent of deep submicron CMOS, RF ICs have become fairly commonplace in the semiconductor market. This has given rise to a new breed of Systems-On-Chip (SOCs) with RF front-ends tightly integrated along with digital, analog and mixed signal circuitry. However, the reliability of the integrated RF front-end continues to be a matter of significant concern and considerable research. A major challenge to the reliability of RF ICs is the fact that their performance is also severely degraded by wide tolerances in on-chip passives and package parasitics, in addition to …

Education And Churchgoing Protestants' Views Of Highly Politicized Christianity, Philip Schwadel

Department of Sociology: Faculty Publications

Many churchgoing Protestants support a highly political role for the Christian religion, endorsing Christian ideals shaping public policy. Highly educated Protestants' emphasis on individualism and protecting civil liberties, however; can encourage a distrust of highly politicized Christianity. Specifically, college and graduate school educated Protestants often want to avoid forcing the Christian religion on secular society. Regression results from the 1996 Religious Identity and Influence Survey show that, among churchgoing Protestants, education is strongly and negatively correlated with supporting laws based on Christian doctrines. Highly educated Protestants are also less likely than high school educated Protestants to advocate Christians attempting to …

Copyright Norms And The Problem Of Private Censorship, Wendy J. Gordon

Faculty Scholarship

Copyright policy must resolve intelligently the tension between upstream and downstream creators, between incentives to create and incentives to use. Downstream at1thors who copy and transform others' images or words as an input to new creativity have. obvious free speech concerns. So do simple copiers in those many instances where even non-creative copying is essential for expressing one's ideas or allegiances.

Part of the tension is economic. Because virtually every author :needs access to predecessor texts, a legislature that increases copyright protection for ·today's creators simultaneously increases tomorrow's costs of creation ¹ or use. But the issue goes far beyond …

Regulation Of Sparc Gene Expression By The Activator Protein 1 Transcription Factor, Joseph William Briggs

Theses and Dissertations in Biomedical Sciences

Overexpression of the c-Jun proto-oncogene in MCF7 breast cancer cells results in a variety of phenotypic changes related to malignant progression including a shift to estrogen independent growth, increased cell motility and invasion. Concurrent with these phenotypic changes are alterations to cellular gene expression patterns. One gene that becomes highly upregulated is SPARC (secreted protein acidic and rich in cysteine). Increased SPARC expression is associated with malignant progression in a variety of different cancers, although little is known regarding the mechanisms of SPARC gene regulation. Therefore, the objectives of this study were: (1) to determine the mechanisms by which c-Jun …

Telecommunications Technology And Sovereignty: Effects On States As Information Transfer Increased From The Speed Of Oxcart To The Speed Of Light, James H. Radford

Graduate Program in International Studies Theses & Dissertations

Sovereignty---the absolute and unlimited power of the state---provides independence of action. Information about actions or intentions of competitors, enemies, or even friends, arriving after extended periods of time, resulted in responses to fait accompli. When information travels nearly instantaneously, states must consider potentially rapid international reactions before the fact. This suggests that since a state's freedom of action has been abridged, the nature of their sovereignty has altered.

This study pursues the research question: In what ways does telecommunications technology affect state sovereignty? The evolution of sovereignty is compared to development of telecommunications technology over four distinct eras, each …

Family Privacy And Death: Antigone, War, And Medical Research, George J. Annas

Faculty Scholarship

Death ends the doctor–patient relationship, and legally the patient's right of privacy dies with the patient. Other privacy interests survive, the most central of which are those of the patient's family to bury the body and to prevent the disclosure of some personal information, such as medical information, about the deceased relative. Just what privacy interests encompass and when they can be overridden by other interests — such as freedom of speech or the claims of public policy or medical research — are evolving.1 Family privacy concerning a family member who has died is at the forefront of a …
