Groundwater Quality In Kentucky: Manganese, R. Stephen Fisher, Bart Davidson
Groundwater Quality In Kentucky: Manganese, R. Stephen Fisher, Bart Davidson
Information Circular--KGS
Manganese is a common constituent of Kentucky rocks and soils and, along with iron is one of the most widespread causes of problems in groundwater supplies. Rainwater seeping through soils and bedrock dissolves manganese and carries it in the groundwater system to wells and springs. In deep, slow-moving systems that lack oxygen, manganese remains in solution. Under oxidizing conditions, however, such as in shallow groundwater systems or where the water is exposed to air, manganese combines with oxygen to form black particles that can clog plumbing fixtures and stain containers and clothing.

Physics and Astronomy Faculty Publications
We present a new diagnostic diagram for mid-infrared spectra of infrared galaxies based on the equivalent width of the 6.2 μm PAH emission feature and the strength of the 9.7 μm silicate feature. Based on the positions in this diagram, we classify galaxies into nine classes ranging from continuum-dominated AGN hot dust spectra and PAH-dominated starburst spectra to absorption-dominated spectra of deeply obscured galactic nuclei. We find that galaxies are systematically distributed along two distinct branches: one of AGN and starburst-dominated spectra and one of deeply obscured nuclei and starburst-dominated spectra. The separation into two branches likely reflects …
Deep Mid-Infrared Silicate Absorption As A Diagnostic Of Obscuring Geometry Toward Galactic Nuclei, N. A. Levenson, M. M. Sirocky, L. Hao, H. W. W. Spoon, J. A. Marshall, Moshe Elitzur, J. R. Houck
Deep Mid-Infrared Silicate Absorption As A Diagnostic Of Obscuring Geometry Toward Galactic Nuclei, N. A. Levenson, M. M. Sirocky, L. Hao, H. W. W. Spoon, J. A. Marshall, Moshe Elitzur, J. R. Houck
Physics and Astronomy Faculty Publications
The silicate cross section peak near 10 μm produces emission and absorption features in the spectra of dusty galactic nuclei observed with the Spitzer Space Telescope. Especially in ultraluminous infrared galaxies, the observed absorption feature can be extremely deep, as IRAS 08572+3915 illustrates. A foreground screen of obscuration cannot reproduce this observed feature, even at a large optical depth. Instead, the deep absorption requires a nuclear source to be deeply embedded in a smooth distribution of material that is both geometrically and optically thick. In contrast, a clumpy medium can produce only shallow absorption or emission, which are …
Economic Analysis Of Cellulase Production Methods For Bio-Ethanol, Jun Zhuang, Mary A. Marchant, Sue E. Nokes, Herbert J. Strobel
Economic Analysis Of Cellulase Production Methods For Bio-Ethanol, Jun Zhuang, Mary A. Marchant, Sue E. Nokes, Herbert J. Strobel
Biosystems and Agricultural Engineering Faculty Publications
The cost of cellulase enzymes has limited the feasibility of producing ethanol from fibrous biomass. Traditional submerged fermentation (SmF) was compared to an alternative method of producing cellulase, solid state cultivation (SSC). Results from an economic analysis indicated that the unit costs for cellulase enzyme production were $15.67 (The prices are all 2004 prices in this article, except otherwise stated. We deflated newer prices to 2004 prices using a deflation factor 0.9 per year and inflated older prices to 2004 prices using an inflation factor 1.1.) per kilogram ($/kg) and $40.36/kg, for the SSC and SmF methods, respectively, while the …
Xenobiotic Transporters In Lactating Mammary Epithelial Cells: Predictions For Drug Accumulation In Breast Milk, Philip Earle Empey
Xenobiotic Transporters In Lactating Mammary Epithelial Cells: Predictions For Drug Accumulation In Breast Milk, Philip Earle Empey
Theses and Dissertations--Pharmacy
Recent literature has established that breast cancer resistance protein (ABCG2) is upregulated during lactation and is responsible for the greater than predicted accumulation of many drugs in breast milk. The objectives of this project were (1) to investigate the role of this transporter in the reported apically-directed nitrofurantoin flux in the CIT3 cell culture model of lactation, (2) to develop a mathematical model for drug transfer into breast milk to relate initial flux rates, steady-state concentrations, efflux ratios, and in vivo milk to serum ratios (M/S) and (3) to identify xenobiotic transporters that are highly expressed, and therefore potentially important …
Secure Image Processing, Nan Hu
Secure Image Processing, Nan Hu
University of Kentucky Master's Theses
In todays heterogeneous network environment, there is a growing demand for distrusted parties to jointly execute distributed algorithms on private data whose secrecy needed to be safeguarded. Platforms that support such computation on image processing purposes are called secure image processing protocols. In this thesis, we propose a new security model, called quasi information theoretic (QIT) security. Under the proposed model efficient protocols on two basic image processing algorithms linear filtering and thresholding are developed. For both problems we consider two situations: 1) only two parties are involved where one holds the data and the other possesses the processing algorithm; …
Determinants Of Young Adult Poverty: A Zip Code Level Analysis, Kaustav Misra
Determinants Of Young Adult Poverty: A Zip Code Level Analysis, Kaustav Misra
University of Kentucky Master's Theses
The war on poverty started in America in the early 1960s, and the poverty rate of 22.4 percent in the year 1959 decreased to 11.1 percent in 1973. Regrettably, this war did not last long enough, as poverty rate increased to 15.1 percent in 1993. In the year 2000 the US poverty rate declined, but always stayed above 11.1 percent. Kentucky also did not achieve success in this poverty war, and it resulted in growing numbers of poor people. Analysis of poverty has always aroused the interest of economists, sociologists and policy makers. Goal of this paper is to intricate …
Approximate Analysis Of Re-Entrant Lines With Bernoulli Reliability Models, Chong Wang
Approximate Analysis Of Re-Entrant Lines With Bernoulli Reliability Models, Chong Wang
University of Kentucky Master's Theses
Re-entrant lines are widely used in many manufacturing systems, such as semiconductor, electronics, etc. However, the performance analysis of re-entrant lines is largely unexplored due to its complexity. In this thesis, we present iterative procedures to approximate the production rate of re-entrant lines with Bernoulli reliability of machines. The convergence of the algorithms, uniqueness of the solution, and structural properties, have been proved analytically. The accuracy of the procedures is investigated numerically. It is shown that the approaches developed can either provide a lower bound or a closed estimate of the system production rate. Finally, a case study of automotive …

Development of an exercise device that can help facilitate this method of specificity training could be beneficial to the sports community and should be investigated. Understanding the trajectory of the foot during the running gait is primary to further pursue this concept. 26 running athletes of varying characteristics participated in this study. Each subjects sex, age, weight, height, leg length, activity level and participation amount in their respective sport was recorded. Retro-reflective cameras …
Gray Code Composite Pattern Structured Light Illumination, Pratibha Gupta
Gray Code Composite Pattern Structured Light Illumination, Pratibha Gupta
University of Kentucky Master's Theses
Structured light is the most common 3D data acquisition technique used in the industry. Traditional Structured light methods are used to obtain the 3D information of an object. Multiple patterns such as Phase measuring profilometry, gray code patterns and binary patterns are used for reliable reconstruction. These multiple patterns achieve non-ambiguous depth and are insensitive to ambient light. However their application is limited to motion much slower than their projection time. These multiple patterns can be combined into a single composite pattern based on the modulation and demodulation techniques and used for obtaining depth information. In this way, the multiple …
A Locally Corrected Nystrm Method For Surface Integral Equations: An Object Oriented Approach, Bryan James Guernsey
A Locally Corrected Nystrm Method For Surface Integral Equations: An Object Oriented Approach, Bryan James Guernsey
University of Kentucky Master's Theses
Classically, researchers in Computational Physics and specifically in Computational Electromagnetics have sought to find numerical solutions to complex physical problems. Several techniques have been developed to accomplish such tasks, each of which having advantages over their counterparts. Typically, each solution method has been developed separately despite having numerous commonalities with other methods. This fact motivates a unified software tool to house each solution method to avoid duplicating previous efforts. Subsequently, these solution methods can be used alone or in conjunction with one another in a straightforward manner. The aforementioned goals can be accomplished by using an Object Oriented software approach. …

Spatial Location Of Electrostatic Discharge Events Within Information Technology Equipment, Robert A. Oglesbee
Spatial Location Of Electrostatic Discharge Events Within Information Technology Equipment, Robert A. Oglesbee
University of Kentucky Master's Theses
In this thesis, a system to locate an electrostatic discharge (ESD) event within an electronic device has been developed. ESD can cause a device to fail legally required radiated emissions limits as well as disrupt intended operation. The system used a fast oscilloscope with four channels, each channel attached to a high frequency near-field antenna. These antennas were placed at known locations in three dimensional space to measure the fields radiated from the ESD event. A Time-Difference-of-Arrival technique was used to calculate the location of the ESD event. Quick determination of the ESD event location provides developers with a tool …
Experimental Investigation Of Pcd Compact Core Drill Performance On Basalt Simulating Sustainable Dry Drilling On Mars, Sandeep Manthri
Experimental Investigation Of Pcd Compact Core Drill Performance On Basalt Simulating Sustainable Dry Drilling On Mars, Sandeep Manthri
University of Kentucky Master's Theses
Missions to Mars aim to characterize rock and subsurface soil samples and possibly bring some back to Earth for more thorough and sophisticated examination. The Martian surface is covered with basalt which has high compressive strength (andamp;gt;130 MPa), and is more difficult to drill than the much softer sedimentary formations that are presently being drilled using diamond core drills. The main objective of this thesis work is to provide the requisite groundwork towards the development of improved and sustainable drills for subsurface drilling applications on Mars, when their goals are obtaining samples. Since progressive drill-wear is substantial in sustained drilling, …
Approaches To Molecular Imprinting On Polysiloxane Scaffolds, Michael Edward Brown
Approaches To Molecular Imprinting On Polysiloxane Scaffolds, Michael Edward Brown
University of Kentucky Master's Theses
Molecular imprinting, a common method used in separations and chromatography to isolate specific molecules via surface binding, has been adapted for applications in biomaterials and related sciences. The objective of this study was to determine the effectiveness of different approaches to molecular imprinting by testing for preferential binding of protein on polysiloxane scaffold surfaces. To test preferential rebinding, the scaffolds were exposed to a mixture of the template protein and a competitor protein with similar size but different chemistry. Lysozyme-imprinted polymers rebound 8.13 0.99% of lysozyme without any competition and 5.1 0.3% of the protein during competition. Lysozyme C peptide …
Nitroreductase: Evidence For A Fluxional Low-Temperature State And Its Possible Role In Enzyme Activity, Peng Zhang
Nitroreductase: Evidence For A Fluxional Low-Temperature State And Its Possible Role In Enzyme Activity, Peng Zhang
University of Kentucky Doctoral Dissertations
The enzyme nitroreductase (NR) catalyzes two-electron reduction of high explosives such as trinitrotoluene (TNT), a wide variety of other toxic nitroaromatic compounds, as well as riboflavin derivatives, using a tightly-bound flavin mononucleotide (FMN) cofactor. It has important environmental and clinical implications. Previous studies have focused on elucidating NRs catalytic mechanism and solving its crystal structure.
In this dissertation work, we first develop and implement new strategies for labeling NR with stable isotopes, and report a completely re-designed protocol for NRs purification. Then we report the successful assignment of over half of NRs backbone resonances using 3d-NMR methods. The most significant …
Design Aids For Air Vessels For Transient Protection Of Large Pipe Networks - A Framework Based On Parameterization Of Knowledge-Base Derived From Optimized Network Models, Dhandayudhapani Ramalingam
Design Aids For Air Vessels For Transient Protection Of Large Pipe Networks - A Framework Based On Parameterization Of Knowledge-Base Derived From Optimized Network Models, Dhandayudhapani Ramalingam
University of Kentucky Doctoral Dissertations
The need for optimal air vessel sizing tools, in protecting large pipe networks from undue transient pressures is well known. Graphical and other heuristic methods reported in literature are limited to sizing the air vessels for simple rising mains. Although attempts have been made to utilize optimization techniques, they have been largely unsuccessful due to their impractical computational requirements. This research work proposes a robust framework for developing surge protection design tools and demonstrates the usefulness of the framework through an example air vessel sizing tool. Efficiency and robustness of the proposed framework are demonstrated by developing a design aid …
University Student Preferences For Therapist Variables Influenced By Student Demographics And Prior Counseling Experiences, Jennifer Ann Weber
University Student Preferences For Therapist Variables Influenced By Student Demographics And Prior Counseling Experiences, Jennifer Ann Weber
University of Kentucky Doctoral Dissertations
Research on psychotherapy has consistently revealed that a portion of the variance in positive outcomes can be explained by therapist variables. Examination of clients preferences for certain therapist characteristics has led to inconsistent results further complicated by differences in participant characteristics. This study on therapist characteristics examines relationships between student-preferred therapist characteristics and demographic information provided by participants in their survey responses. Therapist characteristics under investigation include counseling style and approach to treatment, level of experience and training, and demographic information. This study also validates an online survey as a quality method of investigating university students preferences for therapist characteristics …
Asymmetric Simple Exclusion Process In Two Dimensions, Dmytro Goykolov
Asymmetric Simple Exclusion Process In Two Dimensions, Dmytro Goykolov
University of Kentucky Doctoral Dissertations
Asymmetric simple exclusion process (ASEP) is a driven stochastic lattice model of particles that move preferentially in one direction. If particles move only in one direction, the model is known as totally asymmetric process. Conventionally, preferred direction of motion is chosen to be to the right. Particles interact through the hard core exclusion rule, meaning that no more than one particle is allowed to occupy one lattice site. In this work following ASEP models are presented. First we study square diagonal lattice with particles that occupy one lattice site and move along the square diagonals. Mean-field theory was developed for …

Anisotropic Polarized Light Scatter And Molecular Factor Computing In Pharmaceutical Cleaning Validation And Biomedical Spectroscopy, Aaron Andrew Urbas
University of Kentucky Doctoral Dissertations
Spectroscopy and other optical methods can often be employed with limited or no sample preparation, making them well suited for in situ and in vivo analysis. This dissertation focuses on the use of a near-infrared spectroscopy (NIRS) and polarized light scatter for two such applications: the assessment of cardiovascular disease, and the validation of cleaning processes for pharmaceutical equipment.There is a need for more effective in vivo techniques for assessing intravascular disorders, such as aortic aneurysms and vulnerable atherosclerotic plaques. These, and other cardiovascular disorders, are often associated with structural remodeling of vascular walls. NIRS has previously been demonstrated as …
Pfi-Zeke Spectroscopy And Theoretical Calculations Of Transition Metal-Aromatic Hydrocarbon Complexes, Bradford Raymond Sohnlein
Pfi-Zeke Spectroscopy And Theoretical Calculations Of Transition Metal-Aromatic Hydrocarbon Complexes, Bradford Raymond Sohnlein
University of Kentucky Doctoral Dissertations
Transition metal-aromatic hydrocarbon complexes were generated in a supersonic jet and studied by zero electron kinetic energy (ZEKE) photoelectron spectroscopy and theoretical calculations. The target metal complexes were identified using time-of-flight mass spectrometry, and their ionization thresholds were located via photoionization efficiency spectroscopy. ZEKE spectroscopy was used to measure the ionization energies and vibrational frequencies of the metal complexes. Their electronic states and corresponding molecular structures were determined by comparing the experimental spectra to quantum chemical calculations and Franck-Condon simulations. In this dissertation, the metal complexes of four different aromatic hydrocarbon ligands were studied: benzene (bz), naphthalene (np), biphenyl (bp) …
