XCT Analysis of Decreasing Porosity in the Trenton Limestone of Williams County, Ohio

The Trenton limestone is found in the Michigan and Appalachian Basins, beneath the UticaPoint Pleasant and Antrim shales. The Trenton is of Ordovician age and consists of a fine, lightgrey to dark-brown matrix, stylolites, and secondary dolomite. In Williams County, Ohio, the Trenton limestone displays a decreasing neutron porosity in well log data, and this thesis investigates the porosity decrease. Four boxes of Trenton limestone from Core 3256 were obtained from the Ohio Department of Natural Resources. The Trenton spans a depth of 2267.2 to 2497.8 feet. For this thesis, the following intervals were scanned: 2268–2270 feet (Box 208), 2290–2300 feet (Box 211), 2310– 2320 feet (Box 213), and 2330–2340 feet (Box 215). The core is light grey, and significant oil staining and mineralization are present. The core contains large vugs, many of which are filled with dolomite crystals. This core was scanned using an X-ray computed tomography (XCT) scanner to provide density data in the form of Hounsfield units (HU), and to visualize internal structures and vug frequency. The scans produced average HU values that ranged from +2600 to +2800. Scan images displayed vugs concentrated from 2290–2300 feet, mineralized zones containing dolomite crystals, shale laminations, and fractures in cores. I have used well log data as a comparison to HU values from the XCT scanner to examine the Trenton porosity which continually decreases with depth from 10% to 1% by 2323.5 feet. The porosity may decrease because there is increased mineralization with depth, a decrease in the amount of vugs with depth, or the limestone matrix may change to an increased amount of magnesium (dolomitization); if this is the case, more magnesium-rich rock should occur near the top of the core and decrease with depth. I find that while mineralization and vuggy porosity decrease with depth, the dolomitized zone is the significant factor. The porosity is decreasing as a function of core density and matrix type, as the Trenton limestone transitions from the upper dolomitized zone to a calcite-rich limestone.College of Arts and Sciences Undergraduate Research Scholarship FundOhio Oil and Gas Energy Education Program Scholarship FundFriends of Orton Hall FundOSU Provost ScholarshipNo embargoAcademic Major: Earth Science

Analytical and experimental investigation of a 1/8-scale dynamic model of the shuttle orbiter. Volume 1: Summary report

A 1/8-scale structural dynamics model of the space shuttle orbiter was analyzed using the NASA Structural Analysis System (NASTRAN). Comparison of the calculated eigenvalues with preliminary test data for the unrestrained condition indicate that the analytical model was consistently stiffer, being about 20% higher in the first mode. The eigenvectors show reasonably good agreement with test data. A series of analytical and experimental investigations undertaken to resolve the discrepancy are described. Modifications in the NASTRAN model based upon these investigations resulted in close agreement for both eigenvalues and eigenvectors

Crossover and scaling in a two-dimensional field-tuned superconductor

Using an analysis similar to that of Imry and Wortis, it is shown that the apparent first order superconductor to metal transition, which has been claimed to exist at low values of the magnetic field in a two-dimensional field-tuned system at zero temperature,can be consistentlyinterpreted as a sharp crossover from a strong superconductor to an inhomogeneous state, which is a weak superconductor. The true zero-temperature superconductor to insulator transition within the inhomogenous state is conjectured to be that of randomly diluted XY model. An explaination of the observed finite temperature approximate scaling of resistivity close to the critical point is speculated within this model.Comment: 5 pages, 2 figures, corrected and modified according to referee Report

Effects of calcium ions and quinolinic acid on rat kidney mitochondrial kynurenine aminotransferase

At pH 6.4, rat kidney mitochondrial kynurenine aminotransferase activity is enhanced several-fold by the addition of CaCl2, apparently because Ca++ facilitates the translocation of [alpha]-ketoglutarate, one of the substrates, across the mitochondrial inner membrane. Chloride salts or Mg++, Mn++, Na+, K+, and NH4+ did not have this effect. At pH 6.8, the enzyme activity was near maximal even without added Ca++ but was strongly depressed by either of two calcium chelating agents, quinolinic acid (Q.A.) and ethyleneglycol-bis([beta]-aminoethyl ether)N,N'-tetraacetic acid (EGTA). These observations support the view that Ca++ is involved in regulating kidney mitochondrial translocation of [alpha]-ketoglutarate and that the reported interference of polycarboxylate anion translocation by Q.A. depends on the ability of that agent to chelate Ca++.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/22280/1/0000719.pd
