Investigation Of Rectangular Concrete Columns Reinforced Or Prestressed With Fiber Reinforced Polymer (Frp) Bars Or Tendons, Ching Chiaw Choo

University of Kentucky Doctoral Dissertations

Fiber reinforced polymer (FRP) composites have been increasingly used inconcrete construction. This research focused on the behavior of concrete columnsreinforced with FRP bars, or prestressed with FRP tendons. The methodology was basedthe ultimate strength approach where stress and strain compatibility conditions andmaterial constitutive laws were applied.Axial strength-moment (P-M) interaction relations of reinforced or prestressedconcrete columns with FRP, a linearly-elastic material, were examined. The analyticalresults identified the possibility of premature compression and/or brittle-tension failureoccurring in FRP reinforced and prestressed concrete columns where sudden andexplosive type failures were expected. These failures were related to the rupture of FRPrebars or tendons in compression …

Controlled Synthesis And Functionalization Of Nanoporous Solgel Silica Particles And Gels, Bing Tan

University of Kentucky Doctoral Dissertations

This dissertation addresses three research areas in the sol-gel synthesis of functionalmaterials. The first is the kinetics of hydrolysis and condensation of variousorganoalkoxysilanes. Two mathematical models are developed for the sol-gel reaction inbasic conditions with and without nearest-neighbor effects. Effects on reactivity aremeasured with systematic changes in the organic group structure. Replacing onemethoxy group on the precursor with a methyl group decelerates hydrolysis under basicconditions, but accelerates condensation under acidic conditions. Replacing two methylfunctionalprecursors with one ethylene-bridged precursor accelerates hydrolysis in base,but decelerates condensation in acid. Replacing an ethylene bridge with a hexylenebridge always decelerates the sol-gel reactions. Adding an …

Effects Of Railroad Track Structural Components And Subgrade On Damping And Dissipation Of Train Induced Vibration, Bei Su

University of Kentucky Doctoral Dissertations

A method for numerical simulation of train induced track vibration and wave propagation in subgrade has been proposed. The method uses a mass to simulate the bogie of a train and considers the effect of rail roughness. For this method, rail roughness is considered as a randomly generated signal and a filter is used to block the undesired components. The method predicts the particle velocity around the track and can be applied to many kinds of railroad trackbeds including traditional ballast trackbed and modern Hot mix asphalt (HMA) trackbed. Results from ballast and HMA trackbeds are compared and effects of …

Arr Genes From Arsenate-Reducing Low G+C Gram Positive Bacteria Bacillus Selenitireducens Strain Mls10 And Clostridium Sp. Strain Ohilas, Mrunalini Ranganathan

Electronic Theses and Dissertations

The gene encoding the small subunit of the respiratory arsenate reductase (arrB) from the haloalkaliphilic low G+C Gram positive bacterium Bacillus selenitireducens strain MLS-10 was amplified by PCR, cloned and sequenced. The amplicon was larger (~ 1.2 kb) than predicted indicating that the degenerate reverse primer hybridized to a region further down stream. The amplicon contained all of arrB and the 5'end of another open reading frame. The arrB (693 bp) predicts a 26.3 kDa protein of 230 amino acids with a pI of 5.5 and four iron-sulfur binding domains. The protein shares a 50% identity and 66% similarity with …

Whither Color-Blind Love? A Foucauldian Discourse Analysis Of Love In Black And White, Brian A. Mcelwain

Electronic Theses and Dissertations

Interracial marriage remains one of the most emotionally charged issues in the troubled racial history of the United States. Love in Black and White: The Triumph of Love over Prejudice and Taboo is Mark and Gail Mathabane's relatively popular memoir of their interracial marriage. Using this text as a means of access to the discourses surrounding interracial marriage in the post-Civil Rights era, this study applies the key Foucauldian concepts of discourse, power, subjectivity, and critique to an interpretation of this text in relation to its sociohistorical context. Color-Blind Love emerges as the dominant discourse of the memoir and this …

Effects Of Weight Loss On Visceral Adiposity And Metabolic Adaptations In Diabetic Versus Non-Diabetic Women, Elizabeth C. Konz

University of Kentucky Doctoral Dissertations

Obesity increases the risk for the development of cardiovascular disease, type 2 diabetes and other co-morbid conditions. Type 2 diabetes also is often associated with excessive visceral abdominal fat. Weight loss in obese individuals decreases the risk for developing the co-morbid conditions. Individuals with type 2 diabetes often have a greater difficulty in controlling these complications compared to individuals without type 2 diabetes. The purpose of this study was to evaluate adherence to a medically-supervised low-energy diet (LED) weight loss program and changes in body composition and metabolic parameters after weight loss in women with and without type 2 diabetes. …

Biosynthesis Of Trans-2-Hexenal In Response To Wounding In Strawberry Fruit And Interaction Of Trans-2-Hexenal With Botrytis Cinerea, Kyung Myung

University of Kentucky Doctoral Dissertations

Intact strawberry fruit did not produce detectable t-2-H which is derived from -linolenic acid (18:3). However, in response to wounding by gentle bruising, strawberry fruit emitted t-2-H with the largest quantity produced within 10 min following injury. The level of total lipid 18:3 in the fruit increased two-fold in response to wounding whereas free 18:3 declined slightly (about 30%). At 10 min following wounding, fruit exhibited a 25% increase in 13-lipoxygenase (LOX) activity, which leads to the production of 13-hydroperoxyoctadecatrienoic acid (13-HPOT) from 18:3. The activity of hydroperoxide lyase (HPL), which catalyzes formation of cis-3-hexenal (c-3-H), the precursor of t-2-H, …

Isolation And Characterization Of The Four Arabidopsis Thaliana Poly(A) Polymerase Genes, Lisa Renee Meeks

University of Kentucky Doctoral Dissertations

Poly(A) tail addition to pre-mRNAs is a highly coordinated and essential step in mRNA maturation involving multiple cis- and trans-acting factors. The trans-acting factor, poly(A) polymerase (PAP) plays an essential role in the polyadenylation of mRNA precursors. The Arabidopsis thaliana genome contains four putative PAP genes. We have found, using in silico analysis and transgenic plants expressing GUS under the control of the four PAP promoters, that each of these genes is expressed in overlapping, yet unique patterns. This gives rise to the possibility that these genes are not redundant and may be essential for plant survival. To further test …

Universal Human Rights, The United Nations, And The Telos Of Human Dignity, William J. Wagner

Scholarly Articles

In this short essay, I seek to provide a description of the way the rights framework, by its nature, functions to unify global practice around normative ideals. I then outline obstacles, both theoretical and practical, to the effective functioning of this framework and the advancement of its purpose. Next, I lay out and critique the means that the Church, in its official teaching, proposes for overcoming these obstacles. I conclude by sketching briefly what I understand to be a more adequate program for addressing the impediments that exist to the realization of the aspiration of universal respect for human dignity …

Dick Whittington And Creativity: From Trade To Folklore, From Folklore To Trade, Susanna Frederick Fischer

Scholarly Articles

In this essay, I consider whether increased intellectual property protection for stories and folktales is a wise policy course. I argue that greater intellectual property protections risk serious harm to innovation and creativity by narrowing the public domain and are not the best means to achieve these desired ends. To make my argument, I draw on the Dick Whittington story as both an example of a folktale in danger of overprotection by expanded intellectual property regimes and also as an analogy to the legal treatment of folklore over the past several decades.

Part II focuses on the Dick Whittington story …

Defense Witness As ‘Accomplice’: Should The Trial Judge Give A ‘Care And Caution’ Instruction?, Clifford S. Fishman

Scholarly Articles

At least three federal circuits have approved a trial judge's decision to give a cautionary accomplice testimony instruction when an alleged accomplice testifies for the defendant. Several state courts and at least one military court have done likewise. Other state courts, in contrast, have explicitly disapproved giving such an instruction and courts in at least one state are divided on the issue.

Part I of this article briefly reviews how courts have traditionally determined whether a prosecution witness is an "accomplice,” and will provide representative samples of cautionary instructions. Part II will examine the federal decisions8 upholding giving a similar …

A Suboptimal Receiver With Turbo Block Coding For Ultra-Wideband Communications, Robert H. Morelos-Zaragoza, Timothy Becker, Sim Aquino

Faculty Publications

In this paper, the performance of adaptive equalization and turbo product coding is investigated for pulse-based UWB communications in short-range indoor environments. The sensitivity of adaptive LMS linear and nonlinear (decision-feedback) equalizers with respect to the number of training symbols and number of taps is considered. To reduce the error performance variation with respect to changing channel conditions, a turbo product code (TPC) with two component (31,26,3) Hamming codes is proposed. We report simulation results showing that channel coding not only improves error performance, but also reduces significantly the sensitivity of UWB systems in short-range indoor wireless communications.

His Story/Her Story: A Dialogue About Including Men And Masculinities In The Women’S Studies Curriculum, B. Berila, J. Keller, C. Krone, Jason A. Laker, O. Mayers

Faculty Publications

The article discusses the issue of inclusion of men and masculinities in the Women's Studies curriculum. Women's Studies programs were started to compensate for the male domination in the academics. Women's Studies presented a platform where scholarship for women was produced and taken seriously, female students and faculty could find their say or voice, and theoretical investigations required for the advancement of the aims of the women's movement could take place. If the academy as a whole does not sufficiently integrate Women's Studies into the curriculum, integrating Men's Studies into Women's Studies might end up further marginalizing Women's Studies by …

Self-Assembly Of Ge Quantum Dots On Si(100)- 2×1 By Pulsed Laser Deposition, M. S. Hegazy, H. E. Elsayed-Ali

Electrical & Computer Engineering Faculty Publications

Self-assembled Ge quantum dots are grown on Si(100)- 2×1 by pulsed laser deposition. The growth is studied by in situ reflection high-energy electron diffraction and postdeposition atomic force microscopy. After the completion of the wetting layer, transient hut clusters, faceted by different planes, are observed. When the height of these clusters exceeded a certain value, the facets developed into {305} planes. Some of these huts become {305}-faceted pyramids as the film mean thickness was increased. With further thickness increase, dome clusters developed on the expense of these pyramids. © 2005 American Institute of Physics. [DOI: 10.1063/1.1949285]

Democratization In Afghanistan, Chris Rowe

Human Rights & Human Welfare

What determines whether a specific country embarks on the road to democracy, if it completes that voyage successfully, and finally consolidates democratic values, practices, and institutions? Analysts have debated these issues for decades and have identified a number of historical, structural, and cultural variables that help account for the establishment of successful democracies in some countries and its absence in others. Frequently cited prerequisites for democracy include social and economic modernization; a large and vibrant middle class; and cultural norms and values relating to politics.

Democratization In Iraq, Kate Lotz, Tim Melvin

Neotrusteeship In Iraq, Tim Melvin

Human Rights & Human Welfare

This section deals with literature that examines the role and effectiveness of the Coalition Provisional Authority (CPA) in administering Iraq from 2003 till 2004. Foreign rule plays an important role in developing failed state’s infrastructure and institutions. By examining critical elements of the CPA’s administration, this section focuses on the overall success and failures of the CPA administrative capacity, and what this means for the future of Iraq’s new government. Since the cessation of the CPA, the Iraqi government has had its ups and downs and is still heavily reliant on the American presence. But some positive elements have been …

Human Rights And The War On Terror: Introduction, Jack Donnelly

Human Rights & Human Welfare

War rarely is good for human rights. The decision of the United States to launch a “global war on terror” in response to the suicide airplane bombings in New York and Washington has had predictably negative human rights consequences. In combating a tiny network of violent political extremists, human rights have in various ways, both intentional and unintentional, been restricted, infringed, violated, ignored, and trampled in many countries, sometimes severely.

State-Building In Iraq, Hafsteinn Hafsteinnsson

Human Rights & Human Welfare

Whether the 2003 invasion of Iraq was principally strategic or humanitarian, the United States’ involvement in Iraq has become a complex state-building mission. While there is agreement within the international community on the importance of rebuilding a democratic Iraq, there are many conflicting viewpoints on how this operation should proceed.

Afghanistan, Greg Sanders

Human Rights & Human Welfare

After September 11, Afghanistan became the first battleground of the War on Terror when the Taliban government refused to turn over Osama Bin Laden and other Al Qaeda members. Human rights concerns about these events fall in two areas. First, did the United States violate human rights when it launched Operation Enduring Freedom to overthrow the Taliban and during the subsequent occupation? Second, have the occupation forces and new regime of under the leadership of Hamid Karzai done enough to improve the previously miserable human rights situation in Afghanistan?

Chechnya, Kelley Laird

Human Rights & Human Welfare

The root of animosity between Russians and Chechens extends for more than a century, beginning when Chechens opposed Russia’s conquest of the Caucasus between 1818 and 1917. Tension reached an apex in the 1940s when Stalin deported thousands of Chechens to Siberia and East Asia in fear that they would collaborate with German Nazis.

Colombia, Travis Ning

Human Rights & Human Welfare

The events of September 11 continued of the pattern of redefinition in the conflict in Colombia. The complex war of today actually began decades ago as a small political struggle, which has gradually developed into a large-scale civil war. The continuation and growth of civil strife in Colombia witnessed the emergence of several organized anti-government guerrilla movements. Some of these groups have since been defeated or have integrated themselves into the recognized political system. Others have continued to violently challenge Colombian government authority. Currently, the two most significant anti-government insurgency groups are the Fuerzas Armadas Revolucionarias de Colombia (FARC) and …
