Distal Radioulnar Joint Biomechanics And Forearm Muscle Activity, Joseph Scott Bader

University of Kentucky Doctoral Dissertations

Optimal management of fractures, post-traumatic arthritis and instability of the distal radioulnar joint (DRUJ) requires an understanding of the forces existing across this joint as a function of the activities of daily living. However, such knowledge is currently incomplete. The goal of this research was to quantify the loads that occur at the DRUJ during forearm rotation and to determine the effect that individual muscles have on those loads.

Human and cadaver studies were used to analyze the shear (A-P), transverse (M-L) and resultant forces at the DRUJ and to determine the role that 15 individual muscles had on those …

The broad objective of this project was to examine the interactions between people and bears, with the ultimate goal of improving bear management in a way that addresses stakeholder concerns. Using interviews of regional stakeholders, participant observation, and media reports collected between summer 2003 and fall 2006, I investigated how the presence of black bears in Harlan and Letcher counties in Kentucky has had an impact on area residents. I complemented this information with observations …

Interactions And Effects Of Biomolecules On Au Nanomaterial Surfaces, Manish Sethi

University of Kentucky Doctoral Dissertations

Au nanoparticles are increasingly being used in biological applications. Their use is of interest based upon their unique properties that are achieved at the nanoscale, which includes strong optical absorbances that are size and aggregation state dependent. Such absorbances can be used in sensitive chemical/biological detection schemes where bioligands can be directly attached to the nanoparticle surface using facile methods. Unfortunately, a number of complications persist that prevent their wide-scale use. These limitations include minimal nanoparticle stability in biological-based media of high ionic strength, unknown surface functionalization effects using simple biomolecules, and determining the binding motifs of the ligands to …

Resource Allocation And Efficient Routing In Wireless Networks, Jianjun Yang

University of Kentucky Doctoral Dissertations

In wireless networks, devices (nodes) are connected by wireless links. An important issue is to set up high quality (high bandwidth) and efficient routing paths when one node wants to send packets to other nodes. Resource allocation is the foundation to guarantee high quality connections. In addition, it is critical to handle void areas in order to set up detour-free paths. Moreover, fast message broadcasting is essential in mobile wireless networks. Thus, my research includes dynamic channel allocation in wireless mesh networks, geographic routing in Ad Hoc networks, and message broadcasting in vehicular networks.

Development And Characterization Of Novel Monoclonal Antibodies For Studying Prion Pathogenesis, Chu-Chun Weng

University of Kentucky Master's Theses

Monoclonal antibodies (mAbs) recognizing different regions of PrP are potential tools in the study of prion diseases and immunotherapy. We used shuffled recombinant prion protein containing elk and mouse PrP as antigen to produce monoclonal antibodies in mice. We found that mAb 5C6 mapped to a discontinuous epitope comprised of amino acid 132 and 158 (mouse numbering). Monoclonal anibody 9E9 which maps to a unique N-terminal epitope at amino acid preferentially recognized cervid PrP. In contrast, the epitope of mAb 9H9 is located in the C-terminus and only reacted with mouse and hamster. The epitope for mAb 7H11 appears to …

Pragmatic Modernism: Project [Projekt] And Polish Design, 1956-1970, Mikolaj Czerwinski

University of Kentucky Master's Theses

Recently Scholars of design history began to recognize the phenomenon of Socialist Modernism, the return to modernist aesthetics to Eastern Europe and the Soviet Union during the thaw, the disavowal of Stalinist policies by Nikita Khrushchev after the 20^th Party Congress of the Communist Party in February of 1956 and the resulting turn away from Socialist Realism, a historicist method in architecture that expressed socialist values, which the Stalinist favored. Scholars of art and design argued that Socialist Modernism in Poland constituted an affirmation of the party’s authority and that of the political system because designers who practiced it …

Constructing The Real: The New Photography Of Crewdson, Gursky And Wall, Melissa A. Schwartz

University of Kentucky Master's Theses

A new class of photographs that relies on digital processes, best exemplified by the works of Gregory Crewdson, Andreas Gursky and Jeff Wall all exhibit a ‘not quite right’ quality that calls into question some of the most closely held truisms of photographic thought. Through novel technological processes combined with the elements of the new photography—new scale, fabulist imagery, and implied narrative—these images challenge the nature of photography as a documentary process and, beyond that, the nature of what we understand to be ‘the real’ that is supposedly documented. A visual analysis of these images through the lens of Roland …

Participants were 512 (246 men and 266 women) healthy social drinkers between 21 and 35 years of age. EF was measured using the Behavior Rating Inventory of Executive Functioning – Adult Version (BRIEF-A; Roth, Isquith, & Gioia, 2005) that assesses nine EF components. Following the consumption of either an alcohol or a placebo beverage, participants were tested on a modified version of the Taylor Aggression Paradigm (Taylor, 1967) in which mild electric shocks were received from, and administered to, a …

Development Of Novel Electrophilic Ruthenium(Ii) And Iridium(Iii) Complexes And Their Applications As Homogeneous Catalysts, Ryan R. Ketcham

University of Kentucky Master's Theses

Our aim was to develop the synthetic potential and reaction chemistry of Ir³⁺ and Ru²⁺ electrophiles by preparing well-characterized complexes whose properties are controllable by modification of the ancillary ligand environment Specifically, we prepared a series of ruthenium complexes to serve as selective hydrogenation and hydrogenolysis catalysts of furan derivatives. We also expanded the synthesis of electrophilic Ir³⁺ di-thiolate complexes. These types of compounds could eventually serve as catalysts precursors for the addition of weak nucleophiles to alkynes and nitriles.

Ethnic Identity And Perceived Discrimination As Predictors Of Academic Attitudes: The Mediating And Moderating Roles Of Psychological Distress And Self-Regulation, Hui Chu

University of Kentucky Master's Theses

The current study addressed the deficiency in research by examining risk factors for immigrant children that may lead to academic disengagement (such as ethnic discrimination by peers and teachers, and psychological distress) and resilience factors that promote academic engagement (such as the development of a positive ethnic identity). Children who had stronger, more positive ethnic identities had more positive academic attitudes. Furthermore, the more the children were teased by their peers and graded unfairly by their teachers because of their ethnicity, the more they thought school was less important, less useful and felt less efficacious about school and valued school …

Characterization Of G10h Promoter And Isolation Of Wrky Transcription Factors Involved In Catharanthus Terpenoid Indole Alkaloid Biosynthesis Pathway, Nitima Suttpanta

University of Kentucky Doctoral Dissertations

Catharanthus roseus produces a large array of terpenoid indole alkaloids (TIAs) that are an important source of natural or semi-synthetic anticancer drugs. Biosynthesis of TIAs is tissue-specific and induced by certain phytohormones and fungal elicitors, indicating the involvement of a complex transcriptional control network. However, the transcriptional regulation of the TIA pathway is poorly understood. This study reports the isolation and characterization of the G10H promoter and two WRKY transcription factors regulating TIA biosynthesis.

Geraniol 10-hydroxylase (G10H) controls the first committed step in the biosynthesis of terpenoid indole alkaloids (TIA). The C. roseus G10H promoter sequence was isolated by a …

Three Essays Evaluating Choices Of Teachers And Administrators In Kentucky Public Schools, Nathan Barrett

University of Kentucky Doctoral Dissertations

Public K-12 education is a large enterprise in the United States. Through local, state and federal sources, the U.S. allocated over $610 billion to K-12 public education in 2009 (NCES). Not only is the commitment of public funds for education substantial, the provision of K-12 education is primarily administered by the government in non-market settings through local school districts. It is this institutional environment that generates the impetus for evaluating how those in education make choices in the absence of markets.

Like traditional markets, non-market solutions often fail because the incentives facing individuals and agencies elicit choices which produce outcomes …

Conceptualizing And Improving Red Wine Grape Cultivars Grown In Kentucky, Matthew Simson

University of Kentucky Master's Theses

Wine sensory attributes are associated with quality of wines. Cabernet Franc did not possess good coloration of its wine. Therefore, in the 2009 and 2010 growing seasons, studies including the sampling of four red wine grape cultivars from the end of flowering throughout the rest of the season and applying treatments to Cabernet Franc grapevines at veraison were commenced to address suitability and color enhancement, respectively. The study examining Cabernet Franc, Cabernet Sauvignon, Chambourcin, and Norton looked at sampling their grapes at two-week intervals from times post-flowering to understand the demands of each cultivar during key stages of berry development, …

“Obtuse Women”: Venereal Disease Control Policies And Maintaining A “Fit” Nation, 1920-1945, Evelyn Ashley Sorrell

University of Kentucky Master's Theses

Public health officials and social reformers grew concerned over the prevalence of gonorrhea and syphilis following World War I. The initiatives put in place by authorities to control the spread of venereal disease lacked any concern for women’s health and sought to control their newly found independence and mobility. This thesis examines public health policies related to venereal disease control from 1920-1945 and how these regulations affected women in the United States. Laws and social reform measures such as pre-marital blood tests, the Sheppard-Towner Maternity and Infancy Act, and the use of quarantining prostitutes during World War I and World …

Periodic Trends In Structure Function Relationship Of Organic Heteroacenes, Marsha Loth Grimminger

University of Kentucky Doctoral Dissertations

Our group has previously shown that small changes to molecular structure result in large changes to device properties and stability in organic electronic applications. By functionalizing aromatic heteroacenes with group 14 and group 16 elements, it is possible to control morphology and improve stability for a variety of applications such as thin film transistors and solar cells. Functionalization within the heteroacene core led to changes in electronic structure as observed by electrochemistry and light absorption. By substituting down the periodic table, the carbon heteroatom bond length increased, leading to subtle changes in crystal packing. Absorption maxima were red-­‐shifted and stability …

Social Capital, Solidarity, And Cohort Effect —An Analysis Of The Production Of Social Capital Among Union Miners In Harlan County, Kentucky, Feng Hao

University of Kentucky Master's Theses

The coal industry exercises a pervasive influence on mining communities in Appalachia, even though it exerts enormous damages on the environment and makes limited contributions to employment and the advancement of the communities. One explanation for this paradox offered by Bell is a depletion of social capital among coalfield residents in Central Appalachia (2009). Her data suggests that the “ripping away” of the region’s strong union identity lead to a resocialization, “from a ‘we’ mentality to an ‘I’ mentality, thus demising the store of social capital” (2009:655). My research aims to interpret how social capital resources among union miners was …

Investigation Of The Toxicity And Efflux Of Polychlorinated Biphenyls And Hydroxylated Polychlorinated Biphenyls In Escherichia Coli, Shen Geng

University of Kentucky Master's Theses

Polychlorinated biphenyls (PCBs) are persistent organic pollutants. Due to their properties, PCBs accumulate in the food-chain and post a threat to the health of human beings and wildlife. Hydroxylated PCBs (OH-PCBs) are oxidative metabolites of PCBs and are more hydrophilic than their parent PCBs. One of the best approaches to break down these contaminants is through bioremediation, which is an environmental friendly process that uses microorganisms to restore natural environment.

Towards this goal, we have investigated the toxicity and accumulation of PCBs and OH-PCBs in a Gram-negative bacterium, Escherichia coli. We have also determined the role played by a …

Nongovernmental Organizations And Sex Work In Cambodia: Development Perspectives And Feminist Agendas, Jessica Catherine Schmid

University of Kentucky Master's Theses

This project focuses on nongovernmental organizations (NGOs) in Cambodia that deal, either directly or indirectly, with sex work and sex workers. The NGOs outlined in this study have goals ranging from preventing Cambodian women from entering the commercial sex industry to empowering Cambodian sex workers through the formation of sex worker unions. Through the textual analysis of documents and web materials disseminated by these NGOs and from interviews with representatives from the NGOs, I seek to analyze how underlying assumptions about development and about the commercial sex industry shape the ways in which the personnel leading these NGOs think and …

An Investigation Of The Reynolds Number Dependence Of The Near-Wall Peak In Canonical Wall Bounded Turbulent Channel Flow, Bahareh Estejab

University of Kentucky Master's Theses

An experimental investigation into fully developed high aspect ratio channels was undertaken. A review of the literature reveals that there is a need for accurate measurement of the inner peak value of streamwise turbulence intensity despite the large number of studies already completed. The scattered data on this subject could be attributed either to insufficient channel size (aspect ratio or length) or to hot-wire spatial filtering.

A new, high quality, channel flow facility was designed and constructed, considering the most recent geometric limitation provided in the literature. To obtain accurate results, data were acquired using hot-wire probes with constant viscous-scale …
