Synthesis And Structure-Property Studies Of Organic Materials Containing Fluorinated And Non-Fluorinated # Systems (Small Molecules And Polymers), Yongfeng Wang

University of Kentucky Doctoral Dissertations

Loline alkaloids (LA) are secondary metabolites produced by Epichloandamp;euml; (anamorph, Neotyphodium) grass endophytes. They are toxic and deterrent to a broad range of herbivorous insects but not to livestock. This protective bioactivity has spurred considerable research into the LA biosynthetic pathway. LOL, the gene cluster containing nine genes, is required for LA biosynthesis. The regulation of LOL genes during LA production in culture and in symbio is of interest. In this study, coordinate regulation between LOL gene expression and LA production level was investigated in both MM culture and symbiota. Results showed that expression of LOL genes in N. uncinatum …

Innovative Techniques For Digitizing And Restoring Deteriorated Historical Documents, George V. Landon, Jr.

University of Kentucky Doctoral Dissertations

Recent large-scale document digitization initiatives have created new modes of access to modern library collections with the development of new hardware and software technologies. Most commonly, these digitization projects focus on accurately scanning bound texts, some reaching an efficiency of more than one million volumes per year. While vast digital collections are changing the way users access texts, current scanning paradigms can not handle many non-standard materials. Documentation forms such as manuscripts, scrolls, codices, deteriorated film, epigraphy, and rock art all hold a wealth of human knowledge in physical forms not accessible by standard book scanning technologies. This great omission …

Enhancing Node Cooperation In Mobile Wireless Ad Hoc Networks With Selfish Nodes, Yongwei Wang

University of Kentucky Doctoral Dissertations

In Mobile Ad Hoc Networks (MANETs), nodes depend on each other for routing and forwarding packets. However, to save power and other resources, nodes belonging to independent authorities may behave selfishly, and may not be willing to help other nodes. Such selfish behavior poses a real threat to the proper functioning of MANETs. One way to foster node cooperation is to introduce punishment for selfish nodes. Based on neighbor-monitoring techniques, a fully distributed solution to detect, punish, and re-admit selfish nodes, is proposed here. This solution provides nodes the same opportunity to serve/and be served by others. A light-weight solution …

How, When, And For Whom? Toward A Nuanced Understanding Of The Relation Between African American Ethnic Identity And Mental Health, Ignacio David Acevedo

University of Kentucky Doctoral Dissertations

This study uses a causal modeling approach based on structural equation modeling to examine specific hypotheses regarding the relation among ethnic identity, its components, and various mental health outcomes in African American emerging adults. Data was provided by college students at the Florida Agricultural and Mechanical University. Results did not support a relation between ethnic identity components and adverse mental health. Ethnic identity components were related to positive mental health outcomes; however, this relation differed between gender groups. Among females, the ethnic identity component traditionally labeled ethnic commitment significantly predicted both positive mental health outcomes included in this study. Among …

Precision Measurements Of The Neutron Electric Form Factor At High Momentum Transfers, Ameya Suresh Kolarkar

University of Kentucky Doctoral Dissertations

The neutron, although electrically neutral, is composed of elementary charged particles and as a result, possesses a charge distribution within. The charge distribution can be studied by measuring a quantity called the neutron electric form factor, Gⁿ_E. Experiment E02-013 at Jefferson Lab’s Hall A measured Gⁿ_E at high four-momentum transfer values of Q2 = 1.2, 1.7, 2.5 and 3.4 (GeV/c)² in double polarized semi-exclusive ³He(e, e'n) scattering in quasi-elestic kinematics by measuring the transverse asymmetry A_T of the cross section.

The Heroides In Alfonso X'S General Estoria: Translation, Adaptation, Use, And Interpretation Of A Classical Work In A Thirteenth-Century Iberian History Of The World, J. Javier Puerto Benito

University of Kentucky Doctoral Dissertations

My dissertation analyzes the role of Ovid’s Heroides in Alfonso X’s General Estoria, a massive historical compilation in six volumes that the “Learned King” commissioned in 1272. The way in which eleven of these fictional epistles were incorporated by the Alfonsine translators sheds light on how ancient texts were perceived by medieval scholars. According to the study, King Alfonso relies on Ovid as an accurate historical source and uses the epistles of the heroines as historical documents while preserving their literary dimension.

The thesis is divided into six sections. Chapter one introduces the topic of translation in relation to …

Ecosystem Restoration In The Ouachita National Forest: Evaluating The Pragmatism Of Pre-European Settlement Benchmarks, John Lawrence Davenport

University of Kentucky Doctoral Dissertations

This paper looks at the intersections of nature and culture through a study of forest ecosystem restoration efforts in the Ouachita National Forest (Arkansas and Oklahoma). Ecosystem restoration goals are often informed by a pre-European settlement (PES) condition, with an implicit (and occasionally explicit) assertion that such conditions are both more natural than and preferable to the contemporary state. In many cases resuming pre-suppression fire regimes remains a key mechanism for achieving this restored condition. This study’s three main objectives include: (1) determining how PES benchmarks arose in restoration thought, (2) examining how the choice to use a PES benchmark …

Interpersonal Relationships And Community In Kierkegaard's Thought, J. Michael Tilley

University of Kentucky Doctoral Dissertations

Kierkegaard is generally regarded as a quintessential individualist who leaves no room for social or political engagement. This interpretation is the dominant lens through which many scholars view Kierkegaard, and it also shapes the way Kierkegaard’s thought has been received by his followers and critics. Many recent works have significantly challenged the traditional interpretation of Kierkegaard, but they have not examined the topic systematically. In order to remedy this deficit, this study provides a holistic account of Kierkegaard’s social thought. First, it challenges the dominant view that society as represented by the crowd is simply a foil for Kierkegaard’s individual …

The Effects Of Lobeline On Methamphetamine-Induced Conditioned Place Preference And Dopaminergic Alterations In The Nucleus Accumbens Shell, Nichole Marie Neugebauer

University of Kentucky Doctoral Dissertations

Previous research has suggested that lobeline, a plant alkaloid derived from Lobelia inflate, has potential to be an efficacious pharmacotherapy for the treatment of methamphetamine dependence. In addition to attenuating methamphetamineinduced dopaminergic alterations in vitro, lobeline has been shown to decrease the primary rewarding effects and discriminative stimulus properties of methamphetamine in rats. It is of clinical interest to assess the utility of lobeline to decrease methamphetamine conditioned cues as these cues have been shown to significantly contribute to relapse.

The current studies assessed the ability of lobeline to block the acquisition and expression of methamphetamine-induced conditioned place …

Endothelial Cell Dysfunction By Environmental Contaminants, Elizabeth Grace Oesterling

University of Kentucky Doctoral Dissertations

Within the last few decades, epidemiological evidence has linked exposure to air pollution, both its particles and its organic components, with cardiovascular disease (CVD) progression. CVD is a life long disease with the disruption of the endothelium being the inaugural event in this inflammatory process. The vascular endothelium is extremely susceptible to environmental insults given its tremendous surface area and that it is in constant contact with blood and components circulating within the blood, including xenobiotics. The endothelium is important as a barrier from blood constituents however, dysfunction of this barrier leads to the influx of lymphocytes and granulocytes that …

New Silks Roads: Promises And Perils Of The Internet In The Thai Silk Industry, Mark Graham

University of Kentucky Doctoral Dissertations

The Internet is often touted as a panacea for perceived deficiencies in economic development. Its space-transcending abilities, which can instantly connect producers with consumers, have the potential to cut out intermediaries and to redistribute economic surplus in a more equitable manner. This dissertation asks whether the promises of the Internet are being realized in the Thai silk industry.

The project explores the following questions: (a) At which nodes in the commodity chain is the Internet being used?; (b) How has the introduction of the Internet altered production chains and the flows of capital in the Thai silk industry?; (c) How …

A Systematic Study Of Thermodynamic And Transport Properties Of Layered CaN+1(Ru1-XCrX)NO3n+1, Vinobalan Durairaj

University of Kentucky Doctoral Dissertations

Orbital degrees of freedom play vital role in prompting novel phenomena in ruthenium based Ruddlesden-Popper compounds through coupling of orbits to spin and lattice. Physical properties are then particularly susceptible to small perturbations by external magnetic fields and/or slight structural changes. Current study pertains to the impact when a more-extended 4d Ruthenium ion is replaced by a less-extended 3d Chromium ion.

Perovskite CaRuO₃ (n=∞) is characterized by borderline magnetism and non- Fermi liquid behavior – common occurrences in quantum critical compounds. Remarkably, Cr substitution as low as x=0.05 abruptly drives CaRu_1−xCr_xO₃ from a paramagnetic …

A Novel Class Of Immunoproteasome Catalytic Subunit Lmp2 Inhibitor And Its Therapeutic Potentials In Cancer, Yik Khuan (Abby) Ho

University of Kentucky Doctoral Dissertations

The immunoproteasome, known to play an important role in MHC class I antigen processing and presentation, have been linked to neurodegenerative diseases and hematological cancers. However, the pathophysiological functions of the immunoproteasome in these diseases are still not very well established. This can be attributed mainly to the lack of appropriate molecular probes that selectively target the immunoproteasome catalytic subunits. Herein, we report the development of a small molecular inhibitor (AM) that selectively targets the major catalytic subunit, LMP2, of the immunoproteasome. We show that the compound covalently modifies the LMP2 subunit with high specificity in human prostate …

Paleogene Mirelands Of The Upper Mississippi Embayment, Western Kentucky, Jennifer Marie Klein O'Keefe

University of Kentucky Doctoral Dissertations

Detailed petrography, geochemistry, and palynology together describe the depositional environments and paleoecology of an abandoned meander-fill system in western Kentucky. Oriented block petrography reveals alternating clay-rich and attrinite-rich zones of variable thickness. Woody tissues, where present, do not show dessication features and deflation layers could not be identified. Overall, petrography is indicative of a topogenous mire. Mire palyno-assemblages are less diverse than assemblages reported from clays in the region. Castanea-Cupuliferoidaepollenites assemblages dominate the entire system and other tree pollen are common; fungal spores are relatively uncommon. Weighted statistical analyses reveal ecological groupings beyond this dominance and define botanical succession within …

Color Multiplexed Single Pattern Sli, Neelima Mandava

University of Kentucky Master's Theses

Structured light pattern projection techniques are well known methods of accurately capturing 3-Dimensional information of the target surface. Traditional structured light methods require several different patterns to recover the depth, without ambiguity or albedo sensitivity, and are corrupted by object movement during the projection/capture process. This thesis work presents and discusses a color multiplexed structured light technique for recovering object shape from a single image thus being insensitive to object motion.

This method uses single pattern whose RGB channels are each encoded with a unique subpattern. The pattern is projected on to the target and the reflected image is captured …

Motion Correction Structured Light Using Pattern Interleaving Technique, Raja Kalyan Ram Cavaturu

University of Kentucky Master's Theses

Phase Measuring Profilometry (PMP) is the most robust scanning technique for static 3D data acquisition. To make this technique robust to the target objects which are in motion during the scan interval a novel algorithm called ‘Pattern Interleaving’ is used to get a high density single scan image and making Phase Measuring Profilometry insensitive to ‘z’ motion and prevent motion banding which is predominant in 3D reconstruction when the object is in motion during the scan time

Business Improvement Districts: Should Lexington Establish One?, Melissa A. Hagan

MPA/MPP/MPFM Capstone Projects

Downtown districts are falling victim to surges of new development increasingly taking place outside the city as people seek to escape fast‐paced city life for a more peaceful life in the suburbs. As people move to the suburbs, they either take the businesses with them or the businesses fail to maintain profitability in empty downtowns. Downtown Lexington has been no exception. The recent developments of Hamburg Place and, more recent the developments around Fayette Mall have attracted even more business owners away from downtown.

A new implementation approach for revitalization is gaining momentum, as downtowns are introducing policies that enable …

A Formative Evaluation Of Kentucky’S Environmental Compliance Assistance Program, Bonnie Wathen

MPA/MPP/MPFM Capstone Projects

Kentucky’s Department for Environmental Protection’s Division of Compliance Assistance has the Environmental Compliance Assistance Program (CAP). CAP is a relatively new program that has had little to no evaluation and measurement. However, with limited state resources to be distributed to departments, it is imperative that programs be able to justify their existence. Due to this fact, I chose to evaluate the CAP for my capstone project.

Because inadequate data on outcomes is available at this time, I was unable to conduct a traditional summative evaluation or include any statistical analysis. Instead I chose to conduct a formative, or process, evaluation …

Computer Literacy, Access And Use Of Technology In The Family And Consumer Sciences Classroom, Dana Renee Jenkins

University of Kentucky Master's Theses

For years, schools across the nation have been joining the technology revolution. Today, students have at least some form of technology available to them in school (Roblyer, Castine, andamp; King, 1993; Croxall andamp; Cummings, 2000). This trend is not likely to change, so there is an increasing need for teachers who are literate in the use of the various types of technology. The purpose of this study was to determine if a relationship exists between computer literacy and use of technology, as well as if a relationship exists between teachers access to technology and their use of technology in Family …

Parental Perceptions Of Nutritional Status Of Children With Autism, Rachel Corliss Holt

University of Kentucky Master's Theses

Literature shows that nutritional deficiency and feeding behaviors in neurodevelopmentally disabled children is secondary to an underdeveloped gastrointestinal tract. Fifty (50) parents with children with autism responded to a Nutritional Perception Assessment that they believe their children are at adequate nutritional status. They reported confidence in their nutritional knowledge, yet admitted to concern about the nutritional status of their children. The survey revealed that parents are not seeing a registered dietitian for their nutritional advice, leading to the question of soundness in nutritional information received. A marginal correlation was found between belief in adequate nutritional status of children and the …
