A Kinetic Investigation Of The Reaction Of Ethylenedinitrilotetraacetic Acid (Edta) And Cerium (Iv) In Acid Solution, Sahmia K. Al-Hashimi
A Kinetic Investigation Of The Reaction Of Ethylenedinitrilotetraacetic Acid (Edta) And Cerium (Iv) In Acid Solution, Sahmia K. Al-Hashimi
Masters Theses
"The reaction between Ce(IV) salt solutions and EDTA solution was followed titrimetrically and spectrophotometrically and found to occur in stages. Four equivalents of Ce(IV) are reduced per mole of EDTA almost instantaneously at room temperature or even lower. With increasing temperature and reaction time an ultimate of about 14 equivalents of Ce(IV) is consumer per mole of EDTA. Formaldehyde, carbon dioxide, and other unidentified compounds are the products of oxidation of EDTA with Ce(IV). The kinetics of the reaction in aqueous sulfuric acid (0.09 - 2.95 M̲) was studied over the temperature range 11.7-40⁰ by a spectrophotometric technique. In the …
The Downhole Suspension And Testing Of An Electrodynamic Shear Wave Exciter, Robert Franklin Kehrman
The Downhole Suspension And Testing Of An Electrodynamic Shear Wave Exciter, Robert Franklin Kehrman
Masters Theses
"The work in this research project was aimed at designing a Downhole Electromagnetic Shear Wave Generator capable of delivering a wide frequency band, random, continuous signal. This Exciter was built using a compressed-air driven piston assembly for downhole application. The device was tested in the laboratory in a concrete test facility. It proved to be capable of transmitting a continuous, measurable stress into the concrete in a 100 to 5,000 hertz frequency band"--Abstract, page ii.
Estimation Of Film Boiling Heat Transfer Coefficients For Cylindrical Heaters In Corresponding States Fluids, Gary Joseph Capone
Estimation Of Film Boiling Heat Transfer Coefficients For Cylindrical Heaters In Corresponding States Fluids, Gary Joseph Capone
Masters Theses
"An investigation of film boiling heat transfer was made with cylindrical heaters. The (0.75" O.D.) gold plated, copper heaters were positioned horizontally in pools of liquid argon, nitrogen, and carbon monoxide. A correlation for film boiling corresponding states fluids is derived and discussed. The correlation is a least squares fit of three variables: the diameter of the cylindrical heater, the reduced pressure of the system, and the temperature difference between the heater surface and the saturated pool"--Abstract, page iii.
Spacing Of Explosive Charges, Calvin J. Konya
Spacing Of Explosive Charges, Calvin J. Konya
Masters Theses
"It is generally believed that the spacing of simultaneously initiated collar primed multiple charges is not dependent on the charge length. The stresses generated by explosive charges have been assumed to propagate through a material in a cylindrical manner. this assumption implied that the stress generated in any plane along the charge diameter would have been uniform in magnitude and direction. A finite explosive velocity along with a conical stress wave causes the stresses near the collar to differ from those farther down the column. for this reason, the spacing of charges would be dependent on charge length. An experimental …
Infrared Related Solid State Studies, Donald George Rathbun
Infrared Related Solid State Studies, Donald George Rathbun
Masters Theses
"Infrared reflectivity measurements have been made on single crystal CdS. Classical dispersion analysis has been used in an analysis of the data to obtain the index of refraction, the extinction index, and the dispersion parameters. These are compared with previously published results. The procedure used in this analysis has been outlined for future reference. Also, the shallow donor impurity theory has been used to numerically calculate the d±1 levels for Si and Ge. The theory is extended for the case of the impurity in the bulk semiconductor and the d₀, d±2 and, for high n, the s, p₀, …

Endogenous Metabolism Of Polyporus Sulfureus. : Utilization Of Exogenous Carbohydrates And Fatty Acids, Shu-Mei Wang
Endogenous Metabolism Of Polyporus Sulfureus. : Utilization Of Exogenous Carbohydrates And Fatty Acids, Shu-Mei Wang
Masters Theses
"A strain of Polyporus sulfureus from the collection at the University of Missouri at Rolla was used in this investigation. Organisms of this genus have been reported to produce eburicoic acid in good yield and this was confirmed for the organism used in this study by the isolation and identification of eburicoic acid from the mycelium. Growth studies of this organism showed that 4% malt extract is a better medium than synthetic media containing asparagine, nitrate or nitrate plus 0.5% yeast extract as nitrogen sources. An examination of the pH of the culture medium led to the conclusion that regardless …
The Decomposition Of 5-Hydroxymethyl-2-Furaldehyde Under Gamma Irradiation, William George Bowles
The Decomposition Of 5-Hydroxymethyl-2-Furaldehyde Under Gamma Irradiation, William George Bowles
Masters Theses
"An investigation into the effects of gamma irradiation decomposition of 5-hydroxymethyl-2-furaldehyde (HMF) revealed HMF to be resistant to radiation catalyzed decomposition. A 1.0 normal solution of HMF was irradiated at a dose rate of 4.1 x 10⁵ Rads/hr to a total dose of 8.2 x 10⁶ Rads from a 5000 Curie ⁶⁰Co source. a total of 31 per cent of the HMF decomposed in a zero order reaction, although it was found the HMF decomposed completely under cadmium shielded irradiation in a nuclear reactor with some neutrons present. The reaction rate constant was found to be 4.8 x 10⁻³ moles …

Evaluation And Application Of Dye Tracing In A Karst Terrain, James William Scanlan
Masters Theses
"The purpose of this investigation was to select and evaluate in the laboratory a tracing method appropriate for use in karstic areas, and to perform field tracing studies in the south central Missouri area bounded by the cities of Rolla, St. James, and Salem in an attempt to establish existing direct flow connections between surface and subsurface waters. Fluorescein (sodium salt), Rhodamine WT, and Rhodamine B were evaluated as tracers in the laboratory and the first two dyes were employed in the field. After careful evaluation of a number of adsorbents, extracting solvents, and detection techniques, a method consisting of …
An Analysis Of Dirac Delta Generated Spherical Waves In An Infinite Maxwell Medium, William F. Breig
An Analysis Of Dirac Delta Generated Spherical Waves In An Infinite Maxwell Medium, William F. Breig
Masters Theses
"It is an accepted fact that the simple Maxwell and Voigt models do not usually represent the behavior of real materials. In order to make the results of a model more realistic, other combinations of springs and dashpots must be considered. To understand the more complicated models, it is desirable to have a knowledge of the Maxwell model since this element usually occurs either in series or in parallel in the advanced models. This investigation reports solutions of the spherical wave equation in both the elastic and viscoelastic media. Laplace transform techniques are used to obtain the parameters; stress, velocity, …
Waveform Distortion Caused By A Plasma Sheath, James R. Carl
Waveform Distortion Caused By A Plasma Sheath, James R. Carl
Masters Theses
"A short burst of electromagnetic energy that propagates into and through a plasma medium can react with the plasma medium in several different ways depending on both the characteristics of the plasma and of the pulse. This thesis derives approximations for the plasma transfer function at low pressure (high altitude) and at high pressure (low altitude). The mechanisms that can change the shape of a waveform, in general, are dispersion and breakdown. dispersive distortion at low altitude is shown to exist for electron concentrations well above the resonant concentration for plasma sheaths that are thin compared to one wavelength. Several …
Film Boiling Of Nitrogen From A Spherical Heating Surface At Atmospheric Pressure And Standard Gravity, Juan Jorge MariáNyi
Film Boiling Of Nitrogen From A Spherical Heating Surface At Atmospheric Pressure And Standard Gravity, Juan Jorge MariáNyi
Masters Theses
"A steady state film boiling heat transfer study was conducted at atmospheric pressure, with a heated sphere as the heat transfer surface and liquid nitrogen as the boiling medium. Results indicate that the heat transfer rate in film boiling is not the same around the sphere. For the same heat flux, heat transfer at the sides of the sphere takes place at higher temperatures than at the bottom of the sphere. The data were compared with the equation of Frederking and Clark for spheres (1̲8̲), which was derived to predict steady state conditions at standard, fractional and near zero gravity. …
A Study Of Solvent Effects On The Reaction Between P-Nitrobenzyl Chloride And Hydroxide Ion In Aqueous Dioxane Homogeneous Media, Ken K. Ho
Masters Theses
"The kinetics and activation parameters of the reaction between p̲, p̲' - dinitrostilbene quantitatively, have been studied in five aqueous dioxane solvent systems at five different temperatures between 20⁰ and 40⁰C. At any one temperature the second-order rate constants are minimum in the 30% dioxane solvent mixture, reach a maximum in the 50% dioxane systems, and fall off slightly in the 60% and 70% dioxane systems. The Arrhenius activation energies are highest in the 30% dioxane and lowest in the 70% dioxane systems. The free energies of activation change in the same direction but the magnitude of change is much …
