Conductive Sphere On A Charged Conductive Plane, Birney Robert Fish

Masters Theses

Statement of the Problem: If a conductive sphere is placed in contact with a semi-infinite, conductive plane, the configuration constitutes a three-dimensional equipotential surface. Assuming an isolated plane to be electrically charged to a known surface charge density (σ_°) originally, it is desired to determine the effect produced by placing a sphere on the plane. Specifically, the purpose of this investigation is to determine the force exerted on the sphere normal to the plane, the total charge acquired by the sphere and the perturbation in the electrical field due to its presence on the plane.

A Study Of The Afterglow Of An R-F Excited Mercury Discharge, James A. Aubrecht

Masters Theses

"The short duration afterglow of an r-f discharge in mercury has been examined versus ground state mercury atom density and r-f power. The intensity of the 5771, 5462, 4360, 4079, 4047, 3907, 3651/56, 3342, and 3127/32Å atomic mercury lines were observed to decay as a function of time after the shut off of the active discharge. At temperatures below 333⁰K, all atomic lines decayed exponentially, and no molecular emission was observed. From 333⁰K to 423⁰K, the atomic lines were observed to decay rapidly initially, then exhibit an enhancement effect in intensity which was produced by metastable atom collisions, and finally, …

Noble Gases In The Earth And Its Atmosphere, Robert Anthony Canalas

Masters Theses

"Abundance of noble gases extracted from Fig Tree Shale exhibit a marked deviation from the gas content of eclogitic rocks purported to be mantle material. The abundances of the heavy noble gases in shale were found to exceed the highest known meteoritic values. The abundances of the lighter noble gases were found to be comparable to the abundances of these gases in typical chondrites.

Temperature gradient analyses show that excess heavy gases are released at low temperatures. This is interpreted to indicate a preferential adsorption of the heavy noble gases on fine-grained sediments when these gases were being released from …

The Acidic Transformaion Products Of Indoles Formed By Basidiomycetes, Chung-Ke Chang

Masters Theses

"A survey of the ability of basidiomycetes to convert tryptophan, tryptamine and indole acetic acid to other acidic indoles has been made.

The product formed from tryptamine by Tricholoma nudum was identified as indole acetic acid. The product formed by Cantharellus cibarius from D-tryptophan was identified as N-acetyl-D-tryptophan. The products were purified and identified by means of paper chromatography, thin layer chromatography, infrared spectroscopy and melting points.

The conversion of tryptamine and D-tryptophan was also studied in cultures of Leucopaxillus paradoxus, Hygrophorus conicus and Naucoria confragosa. H. conicus, L. paradoxus and N. confragosa transformed tryptamine and indole acetic acid into …

Analysis Of Trace Elements In River And Spring Waters, Faridoon Andeshire Namdarian

Masters Theses

"Methods for the analysis of trace elements in natural fresh waters were investigated.

Preconcentration of the water samples by reducing the volume and by using cation adsorption resins was studied. It was concluded that cation absorption was the more promising procedure.

The methods used for analysis were absorption spectrophotometry, neutron activation analysis, and atomic absorption spectrophotometry. Atomic absorption spectrophotometry was considered the most suitable method for the analysis of trace elements in waters.

Calcium, copper, lead, zinc, and cadmium were determined in a number of Missouri springs and stream water samples"--Abstract, page ii.

A Study Of The Complexes Of Diketocyclobutenediol, Stewart Michael Condren

Masters Theses

"In this study of the complexes of diketocyclobutenediol, squaric acid, the following original compounds were prepared: zirconyl squarate, indium (III) squarate; titanium (III) squarate, ruthenium (III) squarate, tungsten (VI) squarate, vanadium (III) squarate, and niobium (V) squarate, where squarate refers to the dianion of diketocyclobutenediol. Metal analyses were made on all of these except the ruthenium. However, only three of these metal analyses, namely those for titanium (III) squarate, indium (III) squarate, and zirconyl squarate, warrented [sic] further investigation. Carbon and hydrogen analyses were then made for these three compounds. From the percentage compositions, possible structures were proposed.

The tungsten, …

Comparative Analysis Of Polynomial Root Finding Techniques, Charles Ray O'Daniel

Masters Theses

"The purpose of this study was to investigate and recommend various methods instrumental in finding the roots of a polynomial p(x) = 0. Many different methods are present today, and each has its advantages and disadvantages.

Through thorough investigation, the author has ascertained the key methods to be the method of Bisection, the Newton-Raphson method, and the Bairstow method. Special support in the form of algebraic theorems on the locations and kind of roots are extremely helpful. This combination of theorems and methods provides assurance, speed, and the ability to obtain complex roots.

A Subsurface Geologic Study Of Petroleum Possibilities In The Pennsylvanian Rocks Of Concho County, Texas, Gregory Paul Kraus

Masters Theses

"During early Pennsylvanian time the area now occupied by Concho County was a portion of the Texas peninsula, a broad, low arch with a karst topography developing on its exposed Ellenburger surface. A mid-Pennsylvanian marine transgression inundated the arch and it became an area of clear, shallow water deposition favorable to limestone development. Local sedimentation during Strawn time was largely controlled by its position relative to the Llano uplift and surrounding basins. A variety of subsurface maps were constructed for this study essentially utilizing electric log data. The results indicate that limestones of the Strawn platform facies rapidly change in …

A Petrofabric Study Of The Iron Ore Of Benson Mines, Star Lake, New York, Remo Antonio Masiello

Masters Theses

"The petrofabrics of the host gneiss silicates and Ovate ore grains were studied in thin sections of oriented specimens collected from widely scattered positions in the iron ore deposit at Benson Mines, New York.

Ten oriented specimens selected for petrofabrics study were comprised primarily of feldspar, quartz, garnet and ores, with lesser quantities of biotite and sillimanite. Petrofabric diagrams were prepared for the orientation fabrics of magnetite and biotite in eight of the ten specimens, but sillimanite and quartz were sufficiently abundant for fabric determination in only three specimens. Duplicate thin section and perpendicular sections were utilized to check the …

A Study Of The Molecular Emission And Of The Life Times Of The Metastable States In The Afterglow Spectrum Of A Mercury Discharge, Bruce M. Whitcomb

Masters Theses

"Two methods of studying the spectrum in the early afterglow of a pure mercury sample are discussed. Using a time-sampling technique, information about the intensity of the spectrum as a function of time in the afterglow can be obtained. The intensities of two molecular bands, centered at 3350A and 4850A, are studied. The method of formation of the diatomic mercury molecule and the emission of radiation in the two bands are shown to be density dependent. Mechanisms are presented which explain both the molecular formation and the radiation in the two bands. In an absorption study, the half-lives of the …

Estimation Of Regional Trends In Gravity Using Gram Orthogonal Polynomials, Stanley Dean Thompson

Masters Theses

"A computer program is presented which estimates the trend in a rectangular array of gravity measurements. It is assumed that the regional trend of gravity may be estimated by a low-order polynomial. The method of least-squares is applied to solve for the low-order polynomial which best approximates this trend. Gram orthogonal polynomials are used in the solution of this least-squares surface fit. The program is tested on a known polynomial and on some hypothetical Bouguer gravity data and found to approximate the ʺregional trend of gravity in these cases. The importance of eliminating any significant noise in the observations before …
