Enriched Coal Ash Utilization For Augmenting Production Of Rice Under Acid Lateritic Soil, S. Karmakar, B.N. Mittra, B.C. Ghosh

Coal Combustion and Gasification Products Journal Archive

The use of industrial wastes such as fly ash (FA) or rice husk ash (RHA), along with paper factory sludge (PFS), farmyard manure (FYM), and chemical fertilizers (CF), under integrated nutrient management, was studied in acid lateritic soil on rice. Application of combined fertilization sources increased growth, yield attributes, and yield (up to 92.3 and 9.7% over control and CF, respectively) of wet season rice. The uptake of N, P, K, Ca, Mg, Fe, Mn, Zn, Cu, and Co was increased under combined fertilization sources. The study also indicated that such integrated plant nutrition system improved physico-chemical properties of soil …

Mineralogy And Leaching Characteristics Of Coal Ash From A Major Brazilian Power Plant, Luis F.O. Silva, Colin R. Ward, James C. Hower, Maria Izquierdo, Frans Waanders, Marcos L.S. Oliveira, Zhongsheng Li, Rachel S. Hatch, Xavier Querol

Coal Combustion and Gasification Products Journal Archive

The feed coals, fly ashes and bottom ashes collected from seven different units in a major Brazilian PF power plant have been subjected to comprehensive mineralogical, geochemical, and petrographic studies, to investigate the links between feed coal and ash characteristics. Ashes from two of the units were collected while the coal was being co-fired with oil as part of the boiler start-up procedure, allowing the impact of oil co-firing on ash characteristics also to be evaluated. High proportions of unburnt carbon and high proportions of retained sulphur were found in the fly ashes produced during oil co-firing, probably reflecting less …

Variations In Fly Ash Composition With Sampling Location: Case Study From A Portuguese Power Plant, B. Valentim, A. Guedes, D. Flores, C.R. Ward, J.C. Hower

Coal Combustion and Gasification Products Journal Archive

Fly ash (FA) is a heterogeneous and complex material resulting from coal combustion in thermoelectric power plants (TPP). Therefore, different types of coals, worldwide, produce FAs with different compositions. However, the location of the FA sampling system, inside the TPP, is also important to the composition of the FA produced at each location. A case study of FA from a Portuguese TPP, using several coal and FA characterization techniques (particle size analysis, proximate and ultimate analyses, XRF, SEM/ESEM/EDS, Optical microscopy, XRD, inferred chemistry, and AAS), has shown that FA chemical classification, mineralogy and phase-mineral classification, and trace elements (Cr, Cu, …

Copy Number Variation Shapes Genome Diversity In Arabidopsis Over Immediate Family Generational Scales, Seth Debolt

Horticulture Faculty Publications

Arabidopsis thaliana is the model plant and is grown worldwide by plant biologists seeking to dissect the molecular underpinning of plant growth and development. Gene copy number variation (CNV) is a common form of genome natural diversity that is currently poorly studied in plants and may have broad implications for model organism research, evolutionary biology, and crop science. Herein, comparative genomic hybridization (CGH) was used to identify and interrogate regions of gene CNV across the A. thaliana genome. A common temperature condition used for growth of A. thaliana in our laboratory and many around the globe is 22 degrees C. …

Actions Of Ncx, Pmca And Serca On Short-Term Facilitation And Maintenance Of Transmission In Nerve Terminals, Mohati Desai-Shah, Robin L. Cooper

Biology Faculty Publications

Residual Ca²⁺ can accumulate in the nerve terminal during repetitive stimulation; thus, the basis for short-term facilitation (STF). The plasmalemmal Na⁺/Ca²⁺ exchanger [NCX], the Ca²⁺-ATPase (PMCA) and the sarcoplasmic/endoplasmic reticulum Ca²⁺-ATPase (SERCA) on the endoplasmic reticulum are three important Ca²⁺ regulatory processes in controlling [Ca²⁺]_i. The role of these [Ca²⁺]_i regulators in the development and maintenance of STF was addressed at the neuromuscular junction. When the NCX is compromised by reduced [Na+]o, the EPSP amplitudes decrease, but with KB-R7943 (a reverse blocker of NCX) …

Mental Health And Chronic Disease, Marlene B. Huff, Kimberly K. Mcclanahan, Hatim A. Omar

Pediatrics Faculty Publications

By 2015, worldwide, 1.2 billion children aged 5-14 years will have some kind of significant chronic disease. Although scientific evidence indicates that children with chronic illness have more mental health issues than their healthy peers, many controversies and gaps in the literature exist. It is imperative that an understanding of the effects of chronic illness upon the mental health status of children and adolescents be undertaken. This chapter uses a biopsychosocial perspective to investigate the connection between chronic illness and mental health. The intent of the chapter is to suggest ways that medical and mental health professionals can provide services …

Roles Of The Sarcoplasmic/Endoplasmic Reticulum Ca2+-Atpase, Plasma Membrane Ca2+-Atpase And Na+/Ca2+ Exchanger In Regulation Of Heart Rate In Larval Drosophila, Mohati Desai-Shah, A. R. Papoy, M. Ward, Robin L. Cooper

Biology Faculty Publications

We investigated the roles of three regulatory proteins that impact [Ca²⁺]_i within cardiac myocytes of Drosophila melanogaster. The NCX (Na⁺/Ca²⁺ exchanger), PMCA (plasma membrane Ca²⁺-ATPase) and SERCA (sarcoplasmic/endoplasmic reticulum Ca²⁺-ATPase) were compromised by ionic, pharmacological, mutationalmanipulation, and with a combination of approaches, while heart rate (HR) was monitored. A decrease in SERCA function reduced HR more for intact larva in comparison to a dissected larva. Dissected preparations were used to expose the heart directly to agents. A compromised PMCA also reduced HR; however, attenuated NCX function by low [Na^{+ …}

The Impact Of Wyeth V. Levine On Fda Regulation Of Prescription Drugs, Richard C. Ausness

Law Faculty Scholarly Articles

On March 4, 2009, the United States Supreme Court decided Wyeth v. Levine. In that case, the Court concluded that the plaintiff's failure to warn claim against the makers of the drug Phenergan was not impliedly preempted by the Food, Drug and Cosmetic Act (FDCA). In doing so, the Court rejected the argument of the U.S. Food and Drug Administration (FDA) that tort claims of this nature stand as an obstacle to federal regulatory objectives. This article evaluates the Court's opinion in Wyeth and examines that decision's impact on subsequent litigation in the area of prescription drug labeling. In …

Radical Hysterectomy With Pelvic Lymphadenectomy: Indications, Technique, And Complications, Rachel A. Ware, John R. Van Nagell Jr.

Obstetrics and Gynecology Faculty Publications

Radical hysterectomy with pelvic lymphadenectomy remains the treatment of choice for women with Stages IA₂ and IB₁carcinoma of the cervix, and selected patients with Stage II endometrial cancer. Improvement in surgical techniqe, administration of prophylactic antibiotics, thromboemolic prophylaxis, and advances in critical care medicine have resulted in lower operative morbidity associated with this procedure. Major urinary tract complications such as ureteral injury or vesico-vaginal fistula are now extremely rare (< 1%). Five-year survival rates following this procedure vary according to a number of clinical and histologic variables, and may be as high as 90% in women without lymph node metastases.

Studies Toward The Total Synthesis Of (±)-Α-Yohimbine By Double Annulation, Raghu Ram Chamala

University of Kentucky Doctoral Dissertations

The indole alkaloids, a class of natural products, have received much synthetic attention for years due to their diverse structures and interesting biological properties. We are particularly interested in synthesizing some of the yohimbine alkaloids extracted from the bark of a tall evergreen African tree (Corynanthe yohimbe, commonly known as fringe tree). Yohimbine and its stereoisomers have been tempting targets for synthetic organic chemists for more than fifty years. These compounds feature a pentacyclic ring system with two heteroatoms and five stereogenic centers.

Broadly, the fifteen different synthetic approaches that led to the successful completion of yohimbine alkaloids …

Research questions for this study included the following: 1) Can nursing students explain the difference between health education and health promotion? 2) What have nursing students been exposed to within their curriculum regarding health promotion? 3) What health promoting behaviors are nursing faculty role modeling as perceived by nursing students? 4) What is the role of the nurse in implementing health promotion as perceived by nursing …

Polychlorinated Biphenyl-Induced Endothelial Cell Dysfunction And Its Modulation By Dietary Lipids, Zuzana Majkova

University of Kentucky Doctoral Dissertations

Cardiovascular diseases are the number one cause of death in Western societies. Endothelial dysfunction is an early event in the pathology of atherosclerosis, which is an underlying cause in the majority of cardiovascular events. Exposure to persistent environmental pollutants, such as polychlorinated biphenyls (PCBs), is a risk factor for the development of atherosclerosis.

First, we tested a hypothesis that coplanar PCBs, dioxin-like chemicals with affinity for aryl hydrocarbon receptor (AhR), can stimulate up-regulation of monocyte chemoattractant protein-1 (MCP-1), an endothelium-derived chemokine that attracts monocytes into sub-endothelial space in early stages of atherosclerosis. Coplanar PCBs 77 and 126 increased expression of …

15N Solid-State Nmr Detection Of Flavin Perturbation By H-Bonding In Models And Enzyme Active Sites, Dongtao Cui

University of Kentucky Doctoral Dissertations

Massey and Hemmerich proposed that the different reactivities displayed by different flavoenzymes could be achieved as a result of dominance of different flavin ring resonance structures in different binding sites. Thus, the FMN cofactor would engage in different reactions when it had different electronic structures. To test this proposal and understand how different protein sites could produce different flavin electronic structures, we are developing solid-state NMR as a means of characterizing the electronic state of the flavin ring, via the ¹⁵N chemical shift tensors of the ring N atoms. These provide information on the frontier orbitals. We propose that …

Splendor In The Bluegrass: The Policing Of Drug Related Crime In Lexington, Kentucky, Christine Elizabeth Smith

University of Kentucky Master's Theses

This project is designed as a case study investigating the relationship and practices between residents and police officers in the William Wells Brown neighborhood of Lexington, Kentucky toward the issue of drug-related crime. Employing Michel Foucault‘s work on governmentality and his concept of Splendor, I explore how governance is practiced within the daily negotiations of the WWB neighborhood. I approach this project through the lens of policing because some residents, especially those who comprise the William Wells Brown Neighborhood Association, form a limited partnership with the police department in combating the threat of drug crime in the neighborhood. Drug-related crime …

How Does Background And Training Affect Dance Pedagogy In Higher Education?, Meredith Erin Sims

This study sought to examine the ways background and training impact faculty members‟ pedagogical approach to a dance technique class in a higher education dance department. This study examined the pedagogical knowledge, content knowledge, and pedagogical content knowledge of participants through qualitative methods including interviews, observations, and document analysis. Six major themes emerged from the data: desire to teach, teaching focus, challenging students, planning and preparation, instructional methods, and assessment strategies.

Spheroid Detection In 2d Images Using Circular Hough Transform, Priyanka Chaudhary

University of Kentucky Master's Theses

Three-dimensional endothelial cell sprouting assay (3D-ECSA) exhibits differentiation of endothelial cells into sprouting structures inside a 3D matrix of collagen I. It is a screening tool to study endothelial cell behavior and identification of angiogenesis inhibitors. The shape and size of an EC spheroid (aggregation of ~ 750 cells) is important with respect to its growth performance in presence of angiogenic stimulators. Apparently, tubules formed on malformed spheroids lack homogeneity in terms of density and length. This requires segregation of well formed spheroids from malformed ones to obtain better performance metrics. We aim to develop and validate an automated imaging …

Genetic Diversity, Structure, And Recolonization Patterns Of Kentucky Black Bears, John Tyler Hast

University of Kentucky Master's Theses

After nearly a century of absence, the black bear (Ursus americanus) reappeared in Kentucky during the late 20th century and has since increased in number. Recolonization of bears in the southeastern portion of the state was thought to have been caused by emigration of bears from adjacent states into the Commonwealth, while in the south-central area, bears originated, or natural recolonization may have been supplemented by the translocation of 14 individuals into the Big South Fork National River Recreation Area. To investigate the recolonization patterns of bears in Kentucky, I used 20 microsatellite loci to determine the genetic …

Cover Crops And Tillage Systems For Organic Corn Production In Kentucky, Alfonso Suarez

University of Kentucky Master's Theses

Organic corn (Zea mays L.) producers generally use intensive tillage for weed control. No-till methods reduce soil erosion, conserve water, maintain soil structure and reduce CO₂ emissions. The objective of this study was test different cover crops, tillage systems, N sources and N rates for organic corn production. Two tillage systems (no-till and moldboard plow), two cover crops [hairy vetch (Vicia villosa) and rye (Secale cereale)] and two organic N sources [Louisville Green (LG) and Nature Safe (NF)] at four N rates (45, 90, 135, 180 kg N ha^-1) were evaluated …

Distraction Osteogenesis In An Organ Culture Model, Bradley R. Heil

University of Kentucky Master's Theses

Distraction osteogenesis (DO) is a surgical procedure in which applied strain stimulates new bone growth; however, the underlying mechanisms by which bone cells respond to load are still uncertain. An organ culture model of DO was developed and validated by using linear distraction on the femoral shafts of 5 day old Wistar rats. Two loading regimes were utilized: distracting the bones for 2 hrs on day 1 (GRP I); distracting the bones for 2 hrs on days 1, 3, and 5 (GRP II). After 1 week in culture, the bones were compared to unloaded contralateral controls and assessed for changes. …

Feasibility Of Using 15N-Enriched Escherichia Coli As A Bacterial Tracer In The Cane Run/Royal Spring Basin, Kentucky, John G. Warden

University of Kentucky Master's Theses

A novel tracer method has used ¹⁵N to label Escherichia coli and track the transport of bacteria, a common contaminant, through karst aquifers. Use of this method could provide valuable insight into the movement of bacteria in aquifers, which would help improve remediation methods and strategies. A wild strain of E. coli was isolated from the Cane Run/Royal Spring basin in the Inner Bluegrass region of Kentucky. The strain was serotyped O^-:H^- and virulence testing showed the strain did not have virulence factors of E. coli commonly pathogenic to humans. Five karst microcosms were filled with …

Previous literature has described the scope of clinical pharmacy services in the ED and has, to some extent, presented economic outcomes analyses of the impact of these services (Cohen et al., 2009; Lada and Delgado, 2007). According to Cohen et al., the current literature is still lacking a formal pharmacoeconomic …

Inhibition Of Cholesterol Synthesis By Policosanol, Subhashis Banerjee

University of Kentucky Doctoral Dissertations

Cholesterol is an essential component of the cell, but excessive blood levels are a major risk factor for the development of atherosclerotic plaques that can lead to heart disease and stroke, the foremost cause of premature death in Western societies. Policosanol, a mixture of very long chain alcohols derived from sugarcane, has gained considerable attention among the public as safe and effective means to reduce blood cholesterol levels, a belief based on some early clinical studies. My research investigates one possible mechanism by which policosanol might decrease blood cholesterol levels: the inhibition of cholesterol synthesis in the liver. Previous studies …
