Toxicological Effects Of Endocrine Disrupting Compounds In Bluegill, Pamela Truman Dec 2006

Toxicological Effects Of Endocrine Disrupting Compounds In Bluegill, Pamela Truman

All Theses

The water quality in the Reedy River basin has been shown to be impacted from the diverse and highly urbanized land uses within the watershed. The objective of this study was to examine the observed toxicological effects of EDCs that may be present in the Reedy River watershed by using a suite of biomarkers that were measured in indigenous fish to characterize the exposure and biological effects of these contaminants. Bluegill were analyzed for unnatural estrogenic effects such as: 1) Vitellogenin (VTG) 2) Activity of estrogenic compounds in bile extractions 3) UDP-glucuronosyltransferase (UGT) activity. This biomarker study provides a more …

Functional Association Between Three Archaeal Aminoacyl-Trna Synthetases, Mette Praetorius-Ibba, Corinne D. Hausmann, Molly Paras, Theresa E. Rogers, Michael Ibba Dec 2006

Functional Association Between Three Archaeal Aminoacyl-Trna Synthetases, Mette Praetorius-Ibba, Corinne D. Hausmann, Molly Paras, Theresa E. Rogers, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Aminoacyl-tRNA synthetases (aaRSs) are responsible for attaching amino acids to their cognate tRNAs during protein synthesis. In eukaryotes aaRSs are commonly found in multi-enzyme complexes, although the role of these complexes is still not completely clear. Associations between aaRSs have also been reported in archaea, including a complex between prolyl-(ProRS) and leucyl-tRNA synthetases (LeuRS) in Methanothermobacter thermautotrophicus that enhances tRNAPro aminoacylation. Yeast two-hybrid screens suggested that lysyl-tRNA synthetase (LysRS) also associates with LeuRS in M. thermautotrophicus. Co-purification experiments confirmed that LeuRS, LysRS, and ProRS associate in cell-free extracts. LeuRS bound LysRS and ProRS with a comparable KD …

Perfluoroalkyl (Aryl) Sulfonimide Zwitterions, Hua Mei Dec 2006

Perfluoroalkyl (Aryl) Sulfonimide Zwitterions, Hua Mei

All Dissertations

This research focuses on superacid perfluoroalkyl(aryl) sulfonimides and their derivatives as a source of stable zwitterionic salts. The strong resonance stabilization of sulfonimides imparts unexpected stability to the zwitterions.
Two types of zwitterions were investigated. The first are symmetrical diaryliodonium zwitterions (DZs) as potential photo acid generators (PAGs) for microlithography. Driven by the demand for smaller feature sizes in the microelectronics industry, microlithography using shorter wavelength light has evolved and new PAGs are of interest. New DZs are potentially useful because they have good thermal stability and may be structurally modified to alter their spectral absorption characteristics. As an extension …

We measure the large-scale real-space power spectrum P(k) using luminous red galaxies (LRGs) in the Sloan Digital Sky Survey (SDSS) and use this measurement to sharpen constraints on cosmological parameters from the Wilkinson Microwave Anisotropy Probe (WMAP). We employ a matrix-based power spectrum estimation method using Pseudo-Karhunen-Lo`eve eigenmodes, producing uncorrelated minimum-variance measurements in 20 k-bands of both the clustering power and its anisotropy due to redshift-space distortions, with narrow and well-behaved window functions in the range 0.01 h/Mpc < k < 0.2 h/Mpc. Results from the LRG and main galaxy samples are consistent, with the former providing higher signal-to-noise. Our results are robust to omitting angular and radial density fluctuations and are consistent between different parts of the sky. They provide a striking confirmation of the predicted large-scale CDM power spectrum. Combining only SDSS LRG and WMAP data places robust constraints on many cosmological parameters that complement prior analyses of multiple data sets. The LRGs provide independent cross-checks on m and the baryon fraction in good agreement with WMAP. Within the context of flat CDM models, our LRG measurements complementWMAP by sharpening the constraints on the matter density, the neutrino density and the tensor amplitude by about a factor of two, giving m = 0.24±0.02 (1 ), Pmν < 0.9 eV (95%) and r < 0.3 (95%). Baryon oscillations are clearly detected and provide a robust measurement of the comoving distance to the median survey redshift z = 0.35 independent of curvature and dark energy properties. Within the CDM framework, our power spectrum measurement improves the evidence for spatial flatness, sharpening the curvature constraint tot = 1.05±0.05 from WMAP alone to tot = 1.003±0.010. Assuming tot = 1, the equation of state parameter is constrained to w = −0.94±0.09, indicating the potential for more ambitious future LRG measurements to provide precision tests of the nature of dark energy. All these constraints are essentially independent of scales k > 0.1h/Mpc and associated nonlinear complications, yet agree well with more aggressive published analyses where nonlinear modeling is crucial.

Observation And Tracking Of Tropical Cyclones Using Resolution Enhanced Scatterometry, Richard Ryan Halterman Dec 2006

Observation And Tracking Of Tropical Cyclones Using Resolution Enhanced Scatterometry, Richard Ryan Halterman

Theses and Dissertations

The QuikSCAT scatterometer provides global daily coverage of oceanic near-surface vector winds. Recently, algorithms have been developed to enhance the spatial resolution of QuikSCAT winds from 25~km to 2.5~km posting. These ultra-high resolution winds are used, in comparison with standard L2B data product winds, to observe and track tropical cyclones. Resolution enhanced winds are found to provide additional storm structure such as inner core size and structure and the presence of multiple eyewalls compared with standard resolution winds. The 2.5~km winds are also able to observe storms nearer to the shore than 25~km winds. An analysis of circulation center locatability …

Graphical Microcode Simulator With A Reconfigurable Datapath, Brian Vanburen Dec 2006

Graphical Microcode Simulator With A Reconfigurable Datapath, Brian Vanburen

Theses

Microcode is a symbolic way to simplify control design that allows changing, testing and updating the control unit of processors. By changing the microcode, the same datapath can be used for an entirely different application, such as supporting a completely different instruction set. For these reasons, a majority of control units in modern day processors are microcoded. The object was to investigate and implement a graphical microcode simulator with a reconfigurable datapath and microcode format. By allowing a wide configuration of the datapath, many types of logical processors can be designed and simulated. The resulting implemented simulator is able to …

The Acs Virgo Cluster Survey. Xiv. Analysis Of Color-Magnitude Relations In Globular Cluster Systems, Steffen Mieske, Andres Jordan, Patrick Cote Dec 2006

The Acs Virgo Cluster Survey. Xiv. Analysis Of Color-Magnitude Relations In Globular Cluster Systems, Steffen Mieske, Andres Jordan, Patrick Cote

Articles

We examine the correlation between globular cluster (GC) color and magnitude using HST/ACS imaging for a sample of 79 early-type galaxies (−21.7 < MB < −15.2 mag) with accurate surfacebrightness fluctuation distances from the ACS Virgo Cluster Survey. Using the KMM mixture modeling algorithm, we find a highly significant correlation, z ≡ d(g−z) dz = −0.037 ± 0.004, between color and magnitude for the subpopulation of blue GCs in the co-added GC color-magnitude diagram of the three brightest Virgo cluster galaxies (M49, M87 and M60). The sense of the correlation is such that brighter GCs are redder than their fainter counterparts. For the single GC systems of M87 and M60, we find similar correlations; M49 does not appear to show a significant trend. There is no correlation between (g − z) and Mz for GCs belonging to the red subpopulation. The correlation g ≡ d(g−z) dg for the blue subpopulation is much weaker than z. Using Monte Carlo simulations, we attribute this finding to the fact that the blue subpopulation in Mg extends to higher luminosities than does the red subpopulation, which biases the KMM fit results. The highly significant correlation between color and Mz, however, is a real effect: this conclusion is supported by biweight fits to the same color distributions. We identify two environmental dependencies which influence the derived color-magnitude relation: (1) the slope of the color-magnitude relation decreases in significance with decreasing galaxy luminosity, although it remains detectable over the full luminosity range of our sample; and (2) the slope is stronger for GC populations located at smaller galactocentric distances. These characteristics suggest that the observed trend is, at least partially, shaped by external agents. We examine several physical mechanisms that might give rise to the observed color-magnitude relation including: (1) presence of contaminants like super-clusters, stripped galactic nuclei, or ultra-compact dwarfs; (2) accretion of GCs from low-mass galaxies; (3) stochastic effects; (4) the capture of field stars by individual GCs; and (5) GC self-enrichment. Although none of these scenarios offers a fully satisfactory explanation of the observations, we conclude that self-enrichment and field-star capture, or a combination of these processes, offer the most promising means of explaining our observations.

Single-Step Treatment Of 2,4-Dinitrotoluene Via Zero-Valent Metal Reduction And Chemical Oxidation, J. Mathew Thomas Dec 2006

Single-Step Treatment Of 2,4-Dinitrotoluene Via Zero-Valent Metal Reduction And Chemical Oxidation, J. Mathew Thomas

Theses and Dissertations

Many nitroaromatic compounds (NACs) are considered toxic and potential carcinogens. The purpose of this study was to develop an integrated reductive/oxidative process for treating NAC contaminated waters. The process consists of the combination of zero-valent manganese or iron and a hydroxyl radical based treatment technique. Corrosion promoters were added to the contaminated water to minimize passivation of the metallic species. Water contaminated with 2,4-dinitrotoluen (DNT) was treated with the integrated process using a recirculating batch reactor. It was demonstrated that addition of corrosion promoters to the contaminated water enhanced the rate of reaction of 2,4-DNT with zero-valent iron or manganese. …

A Bandwidth Estimation Method For Ip Version 6 Networks, Marshall Crocker

Theses and Dissertations

Efficiently and accurately estimating bandwidths in packet networks is a problem that has intrigued researchers for years. There is no simple manner for estimating bandwidths in IPv4 networks that is accurate, efficient, flexible, and suitable for a variety of applications. Many of the available estimation techniques suffer from inherent flaws such as inaccuracy due to simple assumptions about the network or an overall high complexity that makes it inappropriate in all but a few highly specific situations. The next generation Internet Protocol, IP version 6, has the functionality necessary to implement feedback mechanisms to assist in accurate bandwidth estimations. This …

Bacterial Source Tracking Of A Watershed Impacted By Cattle Pastures, Celina Phelps Dec 2006

Bacterial Source Tracking Of A Watershed Impacted By Cattle Pastures, Celina Phelps

Theses and Dissertations

Pathogenic microorganisms introduced by cattle may be transported to distant locations via watershed runoff. Escherichia coli, Enterococcus spp., and Streptococcus spp. are a few species present in runoff from land impacted by humans, cattle, and wildlife. Initial data reveals that E. coli concentrations in water are greater in areas impacted by cattle than by humans. And, wildlife contributes greater concentration fluctuations than either humans or cattle. When cattle are removed from a pasture, the bacterial concentrations rapidly decrease; however, slight variations in cattle herd size do not appear to significantly influence these counts. Amplified fragment length polymorphisms (AFLP) and repeated-sequence …

Angiotensin Ii Mediated Regulation Of Signal Transduction In Metabolic Syndrome And Cancer, Ravindra Bharatrao Kolhe Dec 2006

Angiotensin Ii Mediated Regulation Of Signal Transduction In Metabolic Syndrome And Cancer, Ravindra Bharatrao Kolhe

Theses and Dissertations

Patients suffering from hypertension often develop non-Insulin dependent diabetes mellitus (NIDDM), a condition caused by Insulin resistance. Though these patients have normal Insulin receptor (IR) and high levels of Insulin in blood, they fail to have IR-mediated signaling essential for glucose uptake and availability. NIDDM usually begins as insulin resistance, a condition in which Insulin Receptor (IR)-mediated signaling that leads to glucose uptake and glucose availability to cells is inhibited even in the presence of high levels of Insulin in blood. Mechanisms for the development of this Insulin resistance in patients suffering from hypertension are unclear. Angiotensin II (Ang II) …

Effects Of Vasoactive Agents On The Mechanical Properties Of Aortic Heart Valve Leaflets, Rebecca Lynn Pounders Mathis Dec 2006

Effects Of Vasoactive Agents On The Mechanical Properties Of Aortic Heart Valve Leaflets, Rebecca Lynn Pounders Mathis

Theses and Dissertations

Heart valve disease is currently one of the leading forms of heart disease. Current literature has shown that endothelin I, angiotension II and 5-HT are vasoactive agents which cause concentration dependent contractions in aortic valve leaflet tissue. This study tested the mechanical properties of leaflets cut in the radial direction after they were exposed to the agents at varied concentrations or for 0.5, 6 or 24 hours. The elastic modulus, ultimate tensile strength and the yield strength were calculated. In the time trials the elastic modulus and the ultimate tensile strength both showed a significant increase at 24-hours. However, there …

Heat Transfer And Friction In Helically-Finned Tubes Using Artificial Neural Networks, Gregory J. Zdaniuk Dec 2006

Heat Transfer And Friction In Helically-Finned Tubes Using Artificial Neural Networks, Gregory J. Zdaniuk

Theses and Dissertations

The last few decades have seen a significant development of complex heat transfer enhancement geometries such as a helicallyinned tube. The arising problem is that as the fins become more complex, so does the prediction of their performance. In addition to discussing existing prediction tools, this dissertation demonstrates the successful use of artificial neural networks as a correlating method for experimentally- measured heat transfer and friction data of helicallyinned tubes.
