Development Of A Light-Powered Microstructure : Enhancing Thermal Actuation With Near-Infrared Absorbent Gold Nanoparticles., Thomas Matthew Lucas
Development Of A Light-Powered Microstructure : Enhancing Thermal Actuation With Near-Infrared Absorbent Gold Nanoparticles., Thomas Matthew Lucas
Electronic Theses and Dissertations
Development of microscale actuating technologies has considerably added to the toolset for interacting with natural components at the cellular level. Small-scale actuators and switches have potential in areas such as microscale pumping and particle manipulation. Thermal actuation has been used with asymmetric geometry to create large deflections with high force relative to electrostatically driven systems. However, many thermally based techniques require a physical connection for power and operate outside the temperature range conducive for biological studies and medical applications. The work presented here describes the design of an out-of-plane bistable switch that responds to near-infrared light with wavelength-specific response. In …

Pavement deterioration is one of the most important driver for prioritizing pavement management and preservation (PMP) projects. The primary goal of this thesis is to provide reasonable predictive functions from multiple linear regression (MLR) models and artificial neural networks (ANN) that can be adopted by Kentucky Transportation Cabinet (KYTC). Furthermore, we use analytic hierarchy process (AHP) to design a composite pavement distress index in order to help Kentucky Transportation Cabinet (KYTC) prioritizing PMP projects based on 11 different distress indices. Numerical results show that the MLR models provide relatively high R square values of approximately 0.8. Both MLR and ANN …
Expanding The Frontier Of Gold-Catalyzed Cyclizations And Rational Ligand Design., Deepika Malhotra
Expanding The Frontier Of Gold-Catalyzed Cyclizations And Rational Ligand Design., Deepika Malhotra
Electronic Theses and Dissertations
The focus of my dissertation work is to study the gold-catalyzed intramolecular and intermolecular cyclizations involving oxonium intermediates towards the application of synthetically interesting frameworks under ambient conditions and developing a rational approach for the effective catalyst design in gold catalysis. We explored the goldcatalyzed oxygen-transfer reactions of 2-alkynyl-1,5-diketones or 2-alkynyl-5-ketoesters to furnish five-membered rings bearing a quaternary carbon tethered to a carbonyl group. The detailed mechanistic investigation on the newly proposed intramolecular [4+2] cycloaddition mechanism was performed by means of isotopic experiments and quantum chemical calculations. The reactivity of alkynylenolate was investigated in the reactions of allenic ketones and …
Invasive Plants As Drivers And Passengers Of Community Change In A Disturbed Urban Forest., Jeffery A. Masters
Invasive Plants As Drivers And Passengers Of Community Change In A Disturbed Urban Forest., Jeffery A. Masters
Electronic Theses and Dissertations
Invasive species can impact local ecosystems by decreasing biodiversity and local abundances of native species. Invasive species also frequently establish in disturbed habitats. An invasive species may dominate a habitat because the introduced species is a superior competitor (driver model) for resources or because the introduced species is more tolerant of noncompetitive processes such as anthropogenic disturbance that reduces the diversity and abundance of native species (passenger model). Ranunculus ficaria (Ranunculaceae) is an invasive plant species in the northeastern United States, and can be especially dense in urban riparian habitats. It emerges early and forms thick mats of vegetation that …
Informal College Study Groups : Gender And Group Homophily., Brandon Scott Mcreynolds
Informal College Study Groups : Gender And Group Homophily., Brandon Scott Mcreynolds
Electronic Theses and Dissertations
The examination of undergraduate informal college study groups offers not only the ability to better understand student culture, but also the ability to look further into the role that gender plays in a student’s college experience. Further, it is hypothesized that students form and maintain these groups based off homophily. This study uses a mixed methods approach to examine how males and females experience informal study groups differently, along with how a student’s gender informs his or her perception of the group’s purpose, formation and function. Themes such as trust, along with a student’s pre-college background and major, emerged in …
Epigenetic Modifications Associated With Aortic Remodeling In Hyperhomocysteinemia., Nithya Narayanan
Epigenetic Modifications Associated With Aortic Remodeling In Hyperhomocysteinemia., Nithya Narayanan
Electronic Theses and Dissertations
Background: Hyperhomocysteinemia (HHcy) is prevalent in hypertensive patients and is an independent risk factor for aortic pathologies. HHcy is known to cause an imbalance between matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) leading to accumulation of collagen in the aorta resulting in stiffness and development of hypertension. Although the exact mechanism of extracellular matrix remodeling (ECM) is unclear, emerging evidence implicates epigenetic regulation involving DNA methylation. The purpose of the study was to investigate whether inhibition of DNA methylation reduces high blood pressure by regulating aortic ECM remodeling in HHcy. Methods: In the first set of experiments, we …

Myocyte-Specific Overexpression Of Stromal Cell-Derived Factor 1 Facilitates Cardiac Regeneration And Improves Myocardial Function After Infarction In Mice., Detlef Ernst-Rudolf Obal
Electronic Theses and Dissertations
Background: Interruption of cardiac stromal cell-derived factor 1 (SDF1)-CXCR4 axis by chronic AMD3100 administration increased myocardial injury after permanent coronary artery ligation, demonstrating the important role of this chemokine in cardiac regeneration. Hypothesis: Cardiomyocyte-specific conditional overexpression of SDF prevents heart failure after permanent coronary ligation and facilitates cardiac regeneration. Methods and Results: Tetracycline-controlled, a-myosine heavy chain promoter directed overexpression of cardiac SDF resulted in a significant increase of SDF expression (SDF: 8.1 ng / g protein) compared with littermate WT mice (0.02 ng / g protein) four weeks after doxycycline withdrawal. SDF overexpression increased AKT and casein kinase 1 levels …
The Tempest Defending Prospera : The Ideation Of Spiritual Lineage And Practice In Performance For An Afro-Haitian American Actor., Iva-Kristi Maria Papailler
The Tempest Defending Prospera : The Ideation Of Spiritual Lineage And Practice In Performance For An Afro-Haitian American Actor., Iva-Kristi Maria Papailler
Electronic Theses and Dissertations
Imagine: William Shakespeare’s final hero, Prospero and all of his beautiful and majestic White, Italian maleness played by an Afro-Haitian American actress. Something changes. No longer does the audience see a traditional view of the character onstage. The audience sees a woman of African descent delivering lines written for a man of European descent. They may or may not question what they are seeing: certainly, I the actor, must. My Blackness brings an ancestral line to the production that makes a variety of traditional African religions part of Prospera’s spiritual lineage. My Blackness and gender also imbue Prospera with a …
Three-Dimensional Modeling Of The Human Jaw/Teeth Using Optics And Statistics., Aly Saber Abdelrahim
Three-Dimensional Modeling Of The Human Jaw/Teeth Using Optics And Statistics., Aly Saber Abdelrahim
Electronic Theses and Dissertations
Object modeling is a fundamental problem in engineering, involving talents from computer-aided design, computational geometry, computer vision and advanced manufacturing. The process of object modeling takes three stages: sensing, representation, and analysis. Various sensors may be used to capture information about objects; optical cameras and laser scanners are common with rigid objects, while X-ray, CT and MRI are common with biological organs. These sensors may provide a direct or an indirect inference about the object, requiring a geometric representation in the computer that is suitable for subsequent usage. Geometric representations that are compact, i.e., capture the main features of the …

Markers And Mechanisms Of Metabolic Aging., Peter Dziewornu Ahiawodzi
Electronic Theses and Dissertations
Oxidative stress has been implicated in aging and age-related diseases. Using three distinct studies, this dissertation examines associations between lifestyle factors and oxidative stress, and their effects on advanced glycation end products, telomere length, and type II diabetes. Carboxymethyl-lysine (CML), an advanced glycation end-product, has been linked to oxidative stress, cardiovascular and other age-related diseases. The first study investigates the association between sleep disordered breathing (SDB), a source of oxidative stress, and CML. 1002 participants with sleep data from the Cardiovascular Health Study (CHS) were analyzed. SDB was not significantly associated with CML, but after stratification by gender and hemoglobin …
The Role Of Pesticides In Non-Alcoholic Fatty Liver Disease (Nafld)., Laila Al-Eryani 1986-
The Role Of Pesticides In Non-Alcoholic Fatty Liver Disease (Nafld)., Laila Al-Eryani 1986-
Electronic Theses and Dissertations
NAFLD, the most common form of liver disease worldwide, is caused by various factors including industrial chemicals and pesticides exposure. Annually, 5.2 billion pounds of pesticides are used worldwide and can contribute to liver disease, but their role is modestly studied. We hypothesize that pesticides contaminating food supply can worsen diet-induced steatosis via xenobiotic receptor activation. Two human and two rodent databases were utilized and 85% of the 330 chemicals identified associated with NAFLD were pesticides. Eight were selected for evaluating hepatic receptor activation in vitro. The majority including DDT activated hPXR/CAR and mPXR. DDT (100 mg/kg) was studied in …

Electronic Theses and Dissertations
This dissertation explored he relationships among gender, coursetaking, and student outcomes of high school CTE students. The variables analyzed within this study were selected based upon an extensive review of existing literature on gender, stereotypes, occupation, nontraditional careers, and CTE coursetaking and policy. The sample examined in this study came from a Midwestern state’s database of CTE students that were enrolled in high school CTE courses from 2010-2012. Operating under a theory that gender segregation with CTE leads to a continuance of gender segregation in the workforce at large, the purpose of this study was to add to the existing …
Enhancement Of Anaerobic Digestion Of Actual Industrial Wastewaters : Reactor Stability And Kinetic Modeling., Mahyar Ghorbanian
Enhancement Of Anaerobic Digestion Of Actual Industrial Wastewaters : Reactor Stability And Kinetic Modeling., Mahyar Ghorbanian
Electronic Theses and Dissertations
Industrial plants pay disposal costs for discharging their wastewater that can contain pollutants, toxic organics and inorganics, to the sewer based on the Biological Oxygen Demand (BOD) or Chemical Oxygen Demand (COD) of the streams. It has become increasingly expensive for industry to meet stringent regulatory standards. One solution to reduce this cost is to anaerobically degrade the COD content, which in turn generates useful methane gas that can be used to generate useful energy or heat. Anaerobic Digestion (AD) is one of the most suitable renewable resources of conversion of industrial wastewaters to bioenergy, but it is not widely …
Augmentation Of Ras-Induced Cell Transformation : A New Role For Mir-200a In Malignancy., Lindsey Erin Becker
Augmentation Of Ras-Induced Cell Transformation : A New Role For Mir-200a In Malignancy., Lindsey Erin Becker
Electronic Theses and Dissertations
Cancer is a multistep disease that begins with malignant cell transformation and frequently culminates in metastasis and death. MicroRNAs (miRNAs) are small regulatory 21-25-nt RNA molecules and are frequently deregulated in cancer. The majority of miRNAs are estimated to be co-expressed with neighboring miRNAs as clusters. Many miRNA clusters coordinately regulate multiple members of cellular signaling pathways or protein interaction networks. miR-200a is a member of the miR-200 family, which are known to be strong inhibitors of the epithelial to mesenchymal transition. As such, the tumor suppressive role of miR-200a in oncogenesis has been well studied; however, recent studies have …

Forecasting Seasonal Hydrologic Response In Major River Basins., A. M. Tanvir Hossain Bhuiyan
Electronic Theses and Dissertations
Seasonal precipitation variation due to natural climate variation influences stream flow and the apparent frequency and severity of extreme hydrological conditions such as flood and drought. To study hydrologic response and understand the occurrence of extreme hydrological events, the relevant forcing variables must be identified. This study attempts to assess and quantify the historical occurrence and context of extreme hydrologic flow events and quantify the relation between relevant climate variables. Once identified, the flow data and climate variables are evaluated to identify the primary relationship indicators of hydrologic extreme event occurrence. Existing studies focus on developing basin-scale forecasting techniques based …
Neutrophils Alter Epithelial Response To Porphyromonas Gingivalis In A Gingival Crevice Model., Jessica Lynn Bondy-Carey 1987-
Neutrophils Alter Epithelial Response To Porphyromonas Gingivalis In A Gingival Crevice Model., Jessica Lynn Bondy-Carey 1987-
Electronic Theses and Dissertations
A gingival crevice model (epithelial cell-Porphyromonas gingivalis-neutrophil) was established and used to profile gingipain, matrix metalloproteinase (MMP), MMP mediators [neutrophil gelatinase-associated lipocalin (NGAL) and tissue inhibitor of metalloproteinases 1 (TIMP-1)] and cytokine networks. Smoking is the primary environmental risk factor for periodontitis. Therefore, the influence of cigarette smoke extract (CSE) was also monitored in the same model. Porphyromonas gingivalis alone induced low levels of interleukin-1b and interleukin-8 from epithelial cells, but high levels of both cytokines were produced on the addition of neutrophils. Exposure to CSE (100 and 1000 ng mL1 nicotine equivalency) significantly compromised P. gingivalis-induced cytokine secretion (both …

The Performance Of The K6 Scale In A Large Adolescent Sample., Nicholas Chalmer Peiper 1982-
Electronic Theses and Dissertations
This dissertation is an applied research study to examine the performance of the K6 scale that measures serious emotional disturbance (SED) among adolescents. As the K6 was included in the 2012 administration of the Kentucky Incentives for Prevention Survey (KIP), three specific aims are included: 1) confirm the unidimensional structure of the K6 among adolescents using factor analysis; 2) define the prevalence and correlates of adolescent SED among Kentucky students; and 3) utilize latent class analysis (LCA) to empirically derive clinically relevant subtypes of adolescents with SED. Of the 122,718 students who completed the KIP in 2012, approximately 89% provided …
Down Comes The Mountain : Coal Mining And Health In Central Appalachia From 2000 To 2010., James Kent Pugh
Down Comes The Mountain : Coal Mining And Health In Central Appalachia From 2000 To 2010., James Kent Pugh
Electronic Theses and Dissertations
Appalachia is one of the unhealthiest and most economically disadvantaged regions in America. It has higher rates of diseases (including heart disease and cancer) than the rest of the United States. Past research posits that low socioeconomic conditions in Appalachia are the main determinants of health disparities, and a burgeoning body of literature is examines the relationship between coal mining and health. The latter shows that, when controlling for socioeconomic status, health status remains significantly lower in coal-producing, Appalachian counties compared to non-coal producing Appalachian counties. While previous studies examine coal production over one or two years, they do not …
Reclaiming My Body : Black Women And The Fight For Reproductive Justice., Shelby Ray Pumphrey
Reclaiming My Body : Black Women And The Fight For Reproductive Justice., Shelby Ray Pumphrey
Electronic Theses and Dissertations
My paper explores the unique forms of reproductive inequality experienced by poor women of color during the nineteenth and twentieth centuries. By analyzing the experiences of eight African-American women, I will illuminate their struggles and triumphs in the fight for reproductive justice. I focus on the impact of the breeding system of enslavement, inhumane medical experimentation and forced and coercive sterilization. In this work I argue that Black women’s subordinate status across multiple racial, gendered, and socioeconomic systems allows them invaluable insight into said systems and especially how they work in tandem to recreate oppression. Finally I explore the holes …

In this context, this thesis is a further step of a common ongoing investigation focused on predicting NOx emissions from self–sustaining, pulverized coal combustion in dry bottom firing systems. A comprehensive literature research focused on already published NOx prediction approaches from scientific publications based on fundamental quantitative relationships or empirical algorithms and statistical relationships was also carried out in this context. …
Neurodegeneration-Associated Instability Of Ribosomal Dna., Justin Lauren Hallgren 1981-
Neurodegeneration-Associated Instability Of Ribosomal Dna., Justin Lauren Hallgren 1981-
Electronic Theses and Dissertations
Homologous recombination-mediated instability of the repetitively organized ribosomal DNA has been proposed as a mediator of cell senescence in yeast triggering the DNA damage response. High individual variability in the content of human ribosomal DNA suggests that this genomic region remained relatively unstable throughout evolution. Therefore, quantitative real time PCR was used to determine the genomic content of ribosomal DNA in post mortem samples of parietal cortex from 14 young and 9 elderly individuals with no diagnosis of a chronic neurodegenerative/neurological disease. In addition, ribosomal DNA content in that brain region was compared between 10 age-matched control individuals and 10 …
Synthesis Of N-Heterocycles Through Cyclization-Triggered Tandem Additions To Alkynes And The Study Of Promoters In Ionic Reactions., Junbin Han
Electronic Theses and Dissertations
Our research mainly focused on three parts related to the rapid construction of N-heterocycles and the search for ionic reaction promoters. First, N-heterocycles of different ring sizes and with different substitution patterns constitute extremely important structure classes (e.g., alkaloids) in the search for bioactivity. A contemporary challenge in organic synthesis is the mapping of new chemical spaces through tandem or cascade reactions in an atom economical fashion. Our strategy to access these biologically important heterocycles is through a cyclization-triggered tandem addition to alkynes catalyzed by readily available alkynophilic coinage metals like copper. In this manner, a variety of functional groups …

Servants Of My People First : An Examination Of The Political Literacies Of The Black Liberation Front International (Blfi), 1969-1973., Joilynn Karega-Mason
Electronic Theses and Dissertations
This dissertation is a multifaceted project. First, it is a historical work of subversion and revision designed to do two things: (1) apply pressure to trends in rhetoric and composition historiography that have left under-challenged a politics of representation that historically and systematically marked Black college students of the late sixties and early seventies as under-prepared, lacking in linguistic and rhetorical resources and agency, and politically militant yet academically apathetic; and (2) construct a more nuanced portrait of the writer agency of the Black college students of the late sixties and early seventies by examining the political writings of members …

Introduction: This study compared the clinical efficacy of panoramic imaging and Cone Beam Computed Tomography (CBCT) in the optimal placement of virtual dental implants in the posterior edentulous bounded regions of the jaws. Material and methods: From a retrospective audit of patient records, fifty-two subjects were recruited with sixty-one dental implant sites in the maxilla and mandible. Physical measurements of the residual alveolar ridge were performed and consensus decisions of optimal implant length and bone graft necessity were obtained using reformatted panoramic alone (RP) or cross-sectional imaging (XS). Results: Horizontal restorative space measurements greater for RP (p=0.001). Shorter implants were …
Mobilizing Modernist Magazines : Peter Sloterdijk And The Transatlantic Review., Daniel Lee Conrad
Mobilizing Modernist Magazines : Peter Sloterdijk And The Transatlantic Review., Daniel Lee Conrad
Electronic Theses and Dissertations
Many early examinations of “little magazines,” or avant-garde modernist publications, tend to focus on the biographical narratives of their editors or center their discussion on early versions of canonical works in order to develop a greater understanding of the body of work itself. Works like Bernard Poli’s Ford Madox Ford and the Transatlantic Review follow this biographical model, and while well researched and informative, Poli's study strictly focuses on the role Ford played in the publication; in doing so, it limits what can be said about the review’s project to the local editorial level. This thesis, by contrast, seeks to …
The Anti-Obesogenic Effects Of Nitric Oxide., Brian Edward Sansbury 1985-
The Anti-Obesogenic Effects Of Nitric Oxide., Brian Edward Sansbury 1985-
Electronic Theses and Dissertations
Obesity is a strong risk factor for developing type 2 diabetes and cardiovascular disease and has quickly reached epidemic proportions with few tangible and safe treatment options. While it is generally accepted that the primary cause of obesity is energy imbalance, i.e., more calories are consumed than are utilized, understanding how caloric balance is regulated has proven a challenge. Molecular processes and pathways that directly regulate energy metabolism represent promising targets for therapy. In particular, nitric oxide (NO) is emerging as a central regulator of energy metabolism and body composition. NO bioavailability is decreased in animal models of obesity and …
Coal Ash And Children's Sleep : A Community-Based Study., Clara G. Sears
Coal Ash And Children's Sleep : A Community-Based Study., Clara G. Sears
Electronic Theses and Dissertations
Kentucky is the fifth largest producer of coal ash, a by-product of coal combustion. The small spherical coal ash particles contain heavy metals like arsenic, lead, mercury, and cadmium. Coal ash is currently classified as nonhazardous by the EPA, which allows it to be stored in open-air impoundments near low-income communities. The primary object of the study is to determine the prevalence of sleep disruptive behaviors in children exposed to coal ash, compared to a group of demographically similar non-exposed children. Parents or guardians from five neighborhoods surrounding a coal ash storage facility, and one non-exposed community, participated in a …
