Mechanisms Of Retroviral Replication, Timur O. Kabdulov
Mechanisms Of Retroviral Replication, Timur O. Kabdulov
Graduate Theses, Dissertations, and Problem Reports
Specific encapsidation of viral RNA is an essential step of retroviral replication cycle. Extensive biochemical and genetic analyses suggest that majority of retroviruses employ similar mechanisms for specific RNA packaging. Better understanding of mechanisms of this process may help to develop new anti-retroviral drugs against such serious pathogens as human immunodeficiency virus types 1 and 2.;This study concerns with specific packaging of RNA by two simple retroviruses, murine leukemia virus (MLV) and spleen necrosis virus (SNV). SNV proteins can package RNA of both SNV and MLV with similar efficiency. In contrast, MLV proteins cannot package SNV RNA. NC domain was …
Novel Synthesis Of 3,4-Fused Indoles, Jeremiah Wallace Hubbard
Novel Synthesis Of 3,4-Fused Indoles, Jeremiah Wallace Hubbard
Graduate Theses, Dissertations, and Problem Reports
The goal of this project was to synthesize 3,4-fused indoles having a variety of ring sizes and a variety of functional groups. This has been accomplished by the development of a novel palladium-catalyzed route to 3,4-fused indoles. The key steps are two palladium-catalyzed reactions, an intramolecular Heck reaction followed by a reductive N-heteroannulation. Using this route, a number of 3,4-fused indoles were prepared in acceptable yields.

Illustrations From The Cd Collection Of Ollie W. Pottmeyer, Ollie William Pottmeyer
Graduate Theses, Dissertations, and Problem Reports
The Exhibition Illustrations from the CD collection of Ollie W. Pottmeyer is an ongoing reflection of my life. I make soft sculptural fabric pieces as a way of communicating my thoughts and observations of the way society treats marginalized people like me and as a therapeutic healing. This work has enabled others and myself to feel powerful. I have been introspective and have learned things about myself and people of minority like me that I was too ashamed to face in the past. I want people to know that there is something different and I am part of it.
Dsp Implementation Of Trellis Coded Modulation And Distributed Space Time Coding, Yipeng Tang
Dsp Implementation Of Trellis Coded Modulation And Distributed Space Time Coding, Yipeng Tang
Graduate Theses, Dissertations, and Problem Reports
Trellis coded modulation (TCM) combines convolutional coding with modulation, and offers approximately 2--3 dB of coding gain without requiring a corresponding bandwidth expansion. This thesis describes the process of encoding TCM, convolutional codes, decoding using the Viterbi Algorithm (VA), M-ary modulation formats suitable for TCM, and the evaluation of TCM performance.;The concept of multiple TCM, which is a generalization of ordinary TCM, gives rise to the concept of space time codes (STC). With STC, coded signals are transmitted from multiple antennas at the same time over a Rayleigh fading channel. STC combines of transmit diversity, coding and M-ary modulation to …
Teaching Children Qualitative Analysis Of Fundamental Motor Skill, Guoli Liang
Teaching Children Qualitative Analysis Of Fundamental Motor Skill, Guoli Liang
Graduate Theses, Dissertations, and Problem Reports
The purpose of this study is to examine the effects of a qualitative analysis instructional program on elementary school-aged children. More specifically, the study is designed to explore the possibility of teaching elementary school-aged children to observe and detect the errors of individuals performing manipulative motor skills at various skill levels. Can children of those ages (1) initially observe and detect errors, (2) improve their observation and detection after a training intervention, and (3) maintain any such gains?;The study involved a 2 (experimental group/control group) x 2 (third grade/fifth grade) x 3 (pretest/posttest/retention test) design. The participants involved in this …
Studies Of The Initial Stage Of Silicon Carbide Growth On Silicon, Katherine Stewart Ziemer
Studies Of The Initial Stage Of Silicon Carbide Growth On Silicon, Katherine Stewart Ziemer
Graduate Theses, Dissertations, and Problem Reports
The lack of understanding concerning the initial stage of silicon carbide (SiC) growth on silicon (Si) substrates gives rise to heated debates on the growth mechanisms, the characteristics of the "optimal" initial layers, and the processing parameters necessary to produce high-quality cubic or beta silicon carbide (beta-SiC) on these initial layers. If the potential of beta-SiC as a semiconductor for electronic devices is to be realized, the growth of the initial layers (i.e. the initial stage of growth) must be understood and then controlled.;This dissertation presents results from the comparison of the initial stages of beta-SiC growth by gas source …
Texture, Microstructure And Formability Of Aluminum Alloys, Xiang-Ming Cheng
Texture, Microstructure And Formability Of Aluminum Alloys, Xiang-Ming Cheng
University of Kentucky Doctoral Dissertations
Texture, microstructure and formability were studied in Direct Chill Cast (DC) and Strip Cast (SC) aluminum alloys with regard to crystallographic anisotropy, the Portevin-Le Chatelier effect and aging softening behavior. It was found that material properties change greatly with manufacturing processes (DC vs. SC) and chemical composition (3xxx vs. 5 xxx alloys). DC cast hot band materials are usually fully recrystallized and have strong softening textures while SC hot band materials have a rolling structure with strong deformation textures. Softening textures cause 90 earing while deformation textures result in 45 earing after deep drawing. During cold rolling, 90 earing in …

Perceptions Of Long Term Care, Miryam N. Mejia
Capstone Projects and Master's Theses
Improving health care for the elderly in the tri-county area, especially minority aged, requires engaging with the community at large. Comprehensive changes in service delivery and accessibility to health promotion activities will improve the quality of life for an ever-growing population in the 21st century.
