A Five Parameter Study Of Spherical Transient Waves In A Generalized Voigt Model, Liang-Juan Tsay
A Five Parameter Study Of Spherical Transient Waves In A Generalized Voigt Model, Liang-Juan Tsay
Doctoral Dissertations
"Transient spherical waves in a generalized Voigt model were investigated in this study. Both Laplace and fourier transform solutions of the spherical wave equation for a generalized Voigt model were obtained by means of the correspondence principle. Laplace transform solutions were inverted numerically into the domain for the study of the characteristics of the wave forms, and Fourier transform solutions were utilized for the analysis of frequency dependency attenuation in the models. Generalized Voigt models A and B in which a dashpot is connected in series with spring and dashpot components were unable to represent a solid which would simulate …
Isotopic Anomalies Of Noble Gases In Natural Gas, Garry A. Bennett
Isotopic Anomalies Of Noble Gases In Natural Gas, Garry A. Bennett
Masters Theses
"This investigation of the abundance and isotopic composition of noble gases in helium-rich gas wells was undertaken in order to obtain new data which might be used to elucidate the origin of isotopic anomalies of noble gases in the atmosphere. Since noble gases are presently leaking to the atmosphere (Damon and Kulp, 1958a; Bieri et al., 1967-) the isotopic composition of the present atmosphere is not static. The direction of change, and ultimately the origin of anomalous noble gases, might therefore be discovered in studying the noble gases presently leaking from the earth. Since the two major noble gas isotopes …
The Incorporation Of Oxygen-18 Into Oxindole Acid By Cells Of Hygrophorous Conicus, William Green Allen
The Incorporation Of Oxygen-18 Into Oxindole Acid By Cells Of Hygrophorous Conicus, William Green Allen
Masters Theses
"To understand the mechanism of a biological oxidation in which oxygen is incorporated into a substrate, it is necessary to determine the origin of the incorporated oxygen. The objective of this investigation was to determine the origin of the oxygen atom incorporated into indoleacetic acid (IAA) by the IAA oxidase of Hygrophorous conicus through the use of oxygen-18. To determine the source of the oxygen atom incorporated into IAA it is necessary to incubate H. conicus cells with tryptamine or IAA in the presence of ¹⁸O₂ and H₂¹⁶O in one case and ¹⁶O₂ and H₂¹⁸O in another. An examination of …

Characterizing Topologies By Continuous Selfmaps, Derald David Rothmann
Doctoral Dissertations
"Various topological spaces are examined in an effort to describe topological spaces from a knowledge of their class of continuous selfmaps or their class of autohomeomorphisms. Relationships between topologies and their continuous selfmaps are considered. Several examples of topological spaces are given and their corresponding classes of continuous selfmaps are described completely. The problem, given a set X and a topology U when does there exist a topology V either weaker or stronger than U such that the class of continuous selfmaps of (X,V) contains the class of continuous selfmaps of (X,U), is considered. M* and S** spaces are defined …
A Study Of The Energy Loss Spectra Induced By Impact Of 23-125 Kev Protons On Helium Atoms, Franklin Dean Schowengerdt
A Study Of The Energy Loss Spectra Induced By Impact Of 23-125 Kev Protons On Helium Atoms, Franklin Dean Schowengerdt
Doctoral Dissertations
"Results of a study of the inelastic energy loss spectra induced by the impact of protons on gaseous helium at energies of 25 to 125 keV are reported. The spectra were obtained by sending an accelerated beam of protons through a chamber containing the helium target gas, mass-analyzing the forward-scattered beam, then decelerating the beam to a low, well-defined energy for energy analysis and detection. The accelerating potential was varied to produce the spectra. An energy resolution of 2 eV was obtained. Apparent differential cross sections and absolute total cross sections were obtained from the spectra. Total cross sections for …
Longitudinal Optical Phonon-Plasmon Coupling In Ionic Semiconductors, Thomas Joseph Mcmahon
Longitudinal Optical Phonon-Plasmon Coupling In Ionic Semiconductors, Thomas Joseph Mcmahon
Doctoral Dissertations
"The coupling of free carriers and lattice vibrational modes is studied in CdS and InSb by room temperature far infrared reflectance measurements. When the free carrier concentration is such that the plasma frequency is at or near the longitudinal optical mode frequency it is shown that while the transverse modes remain fixed, the longitudinal modes mix with the plasma mode and are shifted in a manner similar to that described by Varga in 1965. Using the dielectric function for the coupled system permits the determination of electron effective masses by reflectance measurements with lattice effects excluded. This method allows one …
Vapor Phase Clustering Model For Water, Richard W. Bolander
Vapor Phase Clustering Model For Water, Richard W. Bolander
Doctoral Dissertations
"Although nucleation phenomena are among the most widespread of all naturally occurring phenomena, even the simplest of nucleation processes, homogeneous nucleation, is poorly understood, particularly the homogeneous nucleation of liquid droplets from water vapor. Homogeneous nucleation involves only molecules of a single substance and does not include the complicating effects due to a substrate or piece of foreign matter. The semiphenomenological liquid drop theories developed nearly three decades ago differ in relatively minor details, with the crucial element of the theory being the derivation of the free energy of formation of the clusters. The clusters are viewed as well-defined incompressible …
A Theoretical Study On The Interpretation Of Resistivity Sounding Data Measured By The Wenner Electrode System, Siew Hung Chan
A Theoretical Study On The Interpretation Of Resistivity Sounding Data Measured By The Wenner Electrode System, Siew Hung Chan
Doctoral Dissertations
"This thesis deals with a theoretical study on the interpretation of resistivity sounding data measured by the Wenner electrode system. The objectives of this investigation are twofold: (i) to derive from the apparent resistivity data some suitable functions from which the resistivity and thickness of each member of the sequence of layers composing the earth may be determined, and (ii) to devise suitable methods for analyzing the resulting functions. In this investigation it is shown that the solution of the boundary value problem associated with an n-layered earth model leads to an integral equation for the Wenner electrode system. This …
A.C. Hall Effect Measurements On Very High Resistivity Materials Exhibiting Electrode Polarization, James Dale Boyd
A.C. Hall Effect Measurements On Very High Resistivity Materials Exhibiting Electrode Polarization, James Dale Boyd
Doctoral Dissertations
"A variable frequency, a.c. Hall effect measurement technique has been designed for mobility studies in very high resistivity (>10⁹ ohm·cm) materials exhibiting electrode space charge polarization effects. It incorporates a neutralized input capacitance preamplifier detector which reduces the total input shunting capacitance, including the sample interelectrode capacitances, to a very low, definable value (<0.1 pf) and thereby provides very high and well defined a.c. detector input impedances (4 x 10⁹ and 7 x 10⁹ ohms at 600 and 200 Hz, respectively). Lumped parameter equivalent circuits have been defined to approximate the electrical behavior of sample materials in the measurement configuration. These equivalent circuits, together with independent measurements of the detector input and sample impedances, allow one to correct the detected Hall voltage and obtain the true value from which mobility data may be derived. The validity of these circuits has been established by independent a.c. and d.c. measurements on photoconductive CdS (dark resistivity >10¹⁰ ohm·cm) which exhibited maximum differences of less than 4%. The existing literature has been critically reviewed and the measurement criteria established by this study have been applied to resolve differences in reported data and to suggest improvements in the resolution of previously employed experimental …
The Statistics Of Finite, One Dimensional Lattice Fluids, John Roger Glaese
The Statistics Of Finite, One Dimensional Lattice Fluids, John Roger Glaese
Doctoral Dissertations
"A one dimensional lattice fluid in which particles are allowed to assume only discrete positions is proposed. Particles are free to move from one lattice site to another interacting through a variety of potentials, including the Lennard-Jones type. The model allows the partition function to be evaluated as a discrete sum over the allowable configurations. Both the canonical ensemble and grand ensemble are treated by computer and a third, the pressure ensemble, is considered and shown to be useful in the theoretical treatment of lattice systems. The thermodynamic behavior of various systems is investigated in both the canonical and grand …

MöSsbauer Effect Studies Of Ferroelectric Phase Transitions In The Pbzro₃ - Pbtio₃ - Bifeo₃ Ternary System, James P. Canner
MöSsbauer Effect Studies Of Ferroelectric Phase Transitions In The Pbzro₃ - Pbtio₃ - Bifeo₃ Ternary System, James P. Canner
Doctoral Dissertations
"The Mössbauer Effect was used to measure the phase transitions in the following ferroelectric compounds: 95% PbZ4₀.₈Ti₀.₂ - 5% BiFeO₃ [and] 95% PbZ4₀.₇Ti₀.₃ - 5% BiFeO₃ and in the antiferroelectric compound: 95% PbZrO₃ - 5% BiFeO₃. The parameters obtained were the area under the resonance peak, the isomer shift, and the electric quadrupole splitting, all as a function of temperature. The ionicity, electric field gradient, and Debye temperature were determined for room temperature. The data are discussed in terms of the lattice vibration model of ferroelectrics and antiferroelectrics, and the structural phase transitions as recently defined for these compounds. The …
Noble Gases: A Record Of The Early Solar System, E. C. Alexander
Noble Gases: A Record Of The Early Solar System, E. C. Alexander
Doctoral Dissertations
"Analyses of the noble gases in samples of iron meteorites are presented which indicate the following: 1. The inclusions of iron meteorites contain noble gases with a wide range of isotopic compositions. 2. The noble gas concentration and isotopic anomalies arc often grossly inhomogeneously distributed within a given inclusion and vary from inclusion to inclusion in a meteorite. 3. Silicate inclusions appear to be the most promising samples for I-Xe and Pu-Xe dating. 4. Graphite and troilite in addition to the silicate inclusion contain significant radiogenic ¹²⁹Xe anomalies. 5. The total I-Xe (and in the case of Toluca silicates total …
Radiative Lifetime Of The B¹Σ⁺ And B³Σ⁺ States Of Carbon Monoxide, John Robert Rogers
Radiative Lifetime Of The B¹Σ⁺ And B³Σ⁺ States Of Carbon Monoxide, John Robert Rogers
Doctoral Dissertations
"The radiative lifetimes of the B¹Σ⁺ and b³Σ⁺ excited states of carbon monoxide were measured at six different pressures: 10, 25, 50, 75, 100, and 125 microns of Hg. The lifetimes were obtained by observation of the radiative decay of the (0,0), (0,1), (0,2), and (1,1) bands of the Angstrom system and the radiative decay of the (0,1), (0,2), (0,3), and (0,4) bands of the Third Positive system. No pressure dependence of the lifetimes was observed for either system. The average lifetime of the v' = 0 vibrational level of the B¹Σ⁺ state was found to be 24.4 x 10⁻⁹ …

Tables based on maximum likelihood estimators are presented for use in making statistical inferences for the Cauchy distribution. Those areas considered include confidence intervals, tests of hypothesis, power of the tests, and tolerance intervals. Both one- and two-sample problems are considered. Tables for testing the hypothesis of whether a sample came from a normal distribution or a Cauchy distribution are presented. The problems encountered in finding maximum likelihood estimators for the Cauchy parameters are discussed, and …
Statistical Inferences For The Generalized Gamma Distribution, Harold Walter Hager
Statistical Inferences For The Generalized Gamma Distribution, Harold Walter Hager
Doctoral Dissertations
"Procedures for handling statistical problems with nuisance parameters are considered with special reference to problems in the three parameter generalized gamma distribution. Maximum likelihood estimation of the parameters of this density has been investigated. Properties of these estimates are established which make it possible to make inferences about the parameters. Discrimination between various models for life testing problems is discussed and the robustness of the Weibull model is advanced. The question of the existence of the maximum likelihood estimates of the parameters for all samples is raised. Empiric evidence is presented indicating that they may not exist for all small …
Trace Element Anomalies In The Igneous Wall Rocks Of Hydrothermal Veins In The Searchlight District, Nevada, Zuhair Al-Shaieb
Trace Element Anomalies In The Igneous Wall Rocks Of Hydrothermal Veins In The Searchlight District, Nevada, Zuhair Al-Shaieb
Masters Theses
"Two hundred and fifty vein and wall rock samples were collected from Chief of the Hill and the Duplex Mines of Searchlight District, Nevada. The samples were collected along lines approximately normal to the veins. They were analyzed for lead, copper, zinc, silver, gold, arsenic, selenium, and molybdenum using neutron actication analysis and atomic absorption spectrophotometry. Gold, silver, copper, lead and zinc show well-developed anomalies in the wall rocks. In most cases, the concentration of these elements decreases gradually with increasing distance from the vein and reaches background values at a distance of 40-120 feet from the vein. Molybdenum and …
The Background Concentrations Of Copper, Lead, And Zinc In Streams Of The "New Lead Belt", Missouri, Nicholas Howard Tibbs
The Background Concentrations Of Copper, Lead, And Zinc In Streams Of The "New Lead Belt", Missouri, Nicholas Howard Tibbs
Masters Theses
"This study was initiated to determine the background concentrations of copper, lead, and zinc in the streams of the Viburnum Trend or New Lead Belt of southeast Missouri. Analytical methods were developed for atomic adsorption spectroscopy. These methods initially consisted of coextraction of cooper, lead, and zinc using the APDC/MIBK system, and finally of extraction of copper by APDC/MIBK and direct analysis of lead and zinc using the newly developed "Sampling Boat" technique. The data obtained from these analyses were arranged in histograms and critically analyzed. The background concentrations were established to be 4-6 ppb for all three elements. Methods …
A Geochemical Study Of The Maquoketa Formation In Pike County, Missouri, John Siegfried Trapp
A Geochemical Study Of The Maquoketa Formation In Pike County, Missouri, John Siegfried Trapp
Masters Theses
"Statistical interpretation of geochemical data was used to determine the environment of deposition of the Maquoketa Formation in Pike County, Missouri. A cyclic sequence was noted which can be best explained by cyclic climatic changes. During the study it was found that elemental relationships which would be expected in a freshly deposited sediment can be found in core samples. In samples from outcrops and quarry faces these relationships have been destroyed. As these elemental relationships reflect mineralogical relationships, serious doubts have arisen as to the validity of petrographic studies of samples taken from outcrops. This study indicates weathering may be …

Masters Theses
"A series of simultaneous nuclei concentration measurements, with four different nuclei counters, have been made. these counters were a Pollak and a Gardner counter supplied by Mr. Paul Allee of the Environmental Science Services Administration, Boulder, Colorado, and a Pollak and a G.E. counter supplied; by Mr. Norman White of the National Center for Air Pollution Control, Cincinnati, Ohio. In the absence of any knowledge of the absolute concentrations in the samples, the data for each of the individual counters have been compared to the averages computed from all four counters. The results of these comparisons indicate the following: (1) …
A Low Frequency Phase Shift Method, Ronnie Carroll Mcmillan
A Low Frequency Phase Shift Method, Ronnie Carroll Mcmillan
Masters Theses
"The phase shift method of measuring atomic lifetimes is particularly useful because it allows us to make measurements in the steady state mode instead of in the transient mode. High frequency phase shift techniques cause many problems. The equipment, which was designed and built to make low frequency phase shift techniques possible, is shown schematically and discussed. The new experimental techniques employed in our apparatus are a phase multiplier and a unique method of using a photomultiplier as a mixer. In the photomultiplier the final dynode is used as the grid of a triode. The next to the last dynode …
Vertical And Lateral Variations In A Welded Tuff, Ted Richard Dinkel
Vertical And Lateral Variations In A Welded Tuff, Ted Richard Dinkel
Masters Theses
"During the Tertiary period, nuée ardente type eruptions spread large deposits of welded tuffs over southwestern Utah and southeastern Nevada. The Wah Wah Springs Tuff is a member of one of the most extensive of these units, the Needles Range Formation of Oligocene age. Its known outcrop area is estimated at 13,000 square miles. Relief was slight in the area during the time of eruption to enable the flows to spread over so large an area. In an effort to analyze the lateral and vertical continuity of the member, a petrographic study was undertaken. The average composition of the Wah …
A Study Of The Evaporation Rates Of Small Freely Falling Water Droplets, Hugh Alan Duguid
A Study Of The Evaporation Rates Of Small Freely Falling Water Droplets, Hugh Alan Duguid
Masters Theses
"The evaporation rates of small (radium 3-9µ), freely falling water droplets were determined. the droplets, produced in a diffusion cloud chamber, were allowed to fall through air of known relative humidity (95-100%) and at three ambient temperatures (25C, 30C, and 35C) in a vertical drift tube. the rates of evaporation were ascertained by recording the drop positions on film at fixed time intervals. The results are compared with several existing theories, and are found to lie between the formulation of Kinzer and Gunn, and the quasistationary theory based on Maxwell's equation"--Abstract, page ii.

"Geologic, stratigraphic, and mineralogic characteristics of the Eocene Wind River and Oligocene White River Formations were determined for the southern portion of the Poison Spider District, Natrona County, Wyoming. Sieve analysis and heavy mineral techniques were used to recognize stratigraphic units, determine their environment of deposition, obtain a better knowledge of the grain size distribution, and to identify a possible source area for the sediments. Particular emphasis was concentrated on the evaluation and interpretation of the available geophysical data (gamma ray and resistivity logs), and geological information which had led to the establishment of several relationships between the local geology …
Infrared Cooling Near Atmospheric Temperature Inversions And Absorber Concentration Variations, Joey Keith Tuttle
Infrared Cooling Near Atmospheric Temperature Inversions And Absorber Concentration Variations, Joey Keith Tuttle
Masters Theses
"Cooling due to infrared radiation near temperature inversions is investigated. Temperature inversions tend to hold pollution below the inversion level. The pollution itself may contribute to the stability of the inversion by selectively cooling certain portions of the atmosphere. A method is developed for evaluating infrared cooling rates at discreet points in the atmosphere. Several sample calculations are given to demonstrate the effects of variations of absorber concentration and lapse rate"--Abstract, page i.

Michael Reactions Part Iv Syntheses With Carboalkoxycarbenes, Frederick Ralph Carman
Masters Theses
"A preliminary investigation has been made involving syntheses with dicarboalkoxycarbenes for the purpose of developing new heterocyclic and alicyclic synthese employing functionalized carbenes. The ultimate goals were the development of a stereospecific synthesis of trans fused and angularly substituted ring systems suitable for conversion to natural products and the development of useful synthetic paths to the azabullvalene system. Although these ultimate goals were not realized, new and improved syntheses of alkyl substituted anisoles and diazomalonic esters, including the first reported synthesis of di-tert-butyl-diazomalonate were accomplished. The addition of dicarboalkoxycarbenes to di-, tri- and tetra- substituted ethylenes, tropilidene and 7-aza-tropilidenes by …
