Transient Temperature Distribution In A Finite Cylinder And An Infinite Cylinder Subjected To Some Boundary Conditions, Harng-Sen Huang

Masters Theses

"This thesis is concerned with the theoretical heat transfer analysis of solid cylinders. The first problem considered is the transient temperature distribution in a finite cylinder. This cylinder has a uniform initial temperature and a uniform constant surrounding temperature. This case is solved by the separation of variables. Combining the charts for the infinite cylinder and the charts for the infinite plate one can determine the solution to this case easily. If a uniform constant surface temperature is prescribed instead of a surrounding temperature, the solution can be obtained from the previous one by charging the Nusselt number to infinity. …

Thin Film Resistor Deposition, Rollie R. Herzog

Masters Theses

"Thin film techniques may be the key to future miniaturization of electrical equipment. The purpose of this thesis was to develop procedures for deposition of thin film resistors and to test these deposited resistors. Starting with a vacuum system, equipment was designed and built to hold and heat the substrate, monitor the substrate temperature and deposited resistance, and to evaporate the material to be deposited. Resistors were deposited and tested for resistance between resistors, capacitance between resistors, and resistance of resistors. A heat aging test was also used comparing resistors with and without a silicon monoxide coating"--Abstract, page ii.

The Construction Of A Single Crystal Neutron Diffraction Unit And Measurement Of Effective Neutron Temperature, Larry Dean Thompson

Masters Theses

"The continued expansion of the nuclear reactor facility and the nuclear engineering program makes it desirable that a neutron spectrometer be available at the reactor facility. This unit would be available for use in graduate and undergraduate laboratories and for graduate research.

A single crystal, white radiation spectrometer including collimator, automatic controls, and shielding was designed and constructed.

The performance of the unit was checked using LiF and Cu crystals. A rocking crystal curve and a θ - 2θ curve was obtained with each crystal. The effective neutron temperature was then determined from the LiF crystal θ - 2θ curve"--Abstract, …

Spectrographic Study Of The Afterglow Of Mercury, Edward E. Stepp, Richard A. Anderson

Physics Faculty Research & Creative Works

The short duration afterglow of 14 Hg lines was examined, at temperatures of 150°, 200°, 250°, and 300°F, in a cell that had been excited by an rf source. All of the lines exhibited a smooth exponential decay at the lowest temperature. At some temperature above 150°F, however, all of the lines, except the 2537- and 4079- Å lines, exhibited an enhancement of intensity in the time region between 50 and 100 µsec. At the highest temperature all of the lines originating from levels at an energy of 8.84 eV or above, except those originating from the 6¹D …

A Study Of The Photomechanical Effect In Silicon, Ronald M. Oglesbee

Masters Theses

"This paper presents the results of an experimental investigation into the photomechanical effect in silicon. The effect was found to be very similar to the electromechanical effect. In both cases the phenomena observed is the softening of a thin surface layer of the material when it is either illuminated or when a current is flowing through the material. An anisotropy was observed in both the hardness and the photomechanical effect. Increasing temperatures tended to "washout" the photomechanical effect. The surface hardness and the photomechanical effect were found to depend heavily on proper surface preparation of the samples, however little dependence …

A Study Of Certain Conservative Sets For Parameters In The Linear Statistical Model, Roger Alan Chapin

Masters Theses

"In the case of the linear statistical model, it has been shown that under certain conditions the confidence intervals obtained by considering the parameters one at a time are conservative when used as a joint confidence region, using the product of confidences as the confidence. However, nothing had been known of how conservative they are. This research provides accurate estimates of the true confidence for these cases.

Also, it has not yet been proved that they are indeed conservative for all cases. It is thought that they are, and the results of this research support this conjecture"--Abstract, page ii.

The Cementing Of Hydraulically Placed Tailing Fill By The Oxidation Products Of Pyrrhotite, Stanley H. Alder

Masters Theses

"This thesis has been prepared to make available basic information on the use of the oxidation products of pyrrhotite to cement hydraulic tailing stope fill. As nothing has been published on this subject to date, a review has been made of pertinent information culled from accounts of work in related fields. From this study, a set of equations representing the most likely pyrrhotite oxidation reactions has been evolved and tests supporting these equations performed. Samples of fill, each containing from one to six percent of pyrrhotite, were cemented in the laboratory. They were then examined microscopically, subjected to unconfined compressive …

Hot Isostatic Compaction Of Graphite, Donald C. Carmichael, P. D. Ownby, Edwin S. Hodge

Materials Science and Engineering Faculty Research & Creative Works

The effects of temperature, pressure, and graphite starting material on the density, isotropy, and strength of dense graphite material prepared by hot isostatic compaction of graphite powders were examined. Process equipment was developed to permit operation at temperatures up to 2700 C under a 1600-atom isostatic pressure of inert gas . The isotropy of graphite compacts was determined by neutron diffraction. Relatively isotropic, high-purity graphites were produced having modest isotropic tensile strength and extremely high density (up to 2.24 g per cm³, or 99 per cent of theoretical).

The Separation Of Radioactive Technetium And Zirconium By Electrodialysis And A Study Of The Behavior Of Technetium In Aqueous Solutions, William Victor Andoe

Masters Theses

"The rapid increase in radioisotope applications necessitates improved technology for separation and purification of the fission product elements. Electrodialysis techniques employing Permutit anion exchange membrane(3148) were used to separate technetium from zirconium. The method was based upon the stability of the pertechnetate ion in alkaline solutions and the precipitation of zirconium from alkaline solutions. The separation of radiotechnetium and radiozirconium was effected with a two cell electrodialysis unit employing an anion exchange membrane. The solution medium consisted of fluoride and nitrate ions which were made basic with sodium hydroxide. The minimum basicity for a good separation was 0.1N NaOH"--Abstract, page …

Geology Of Cienega Mining District, Northwestern Yuma County, Arizona, Elias Zambrano

Masters Theses

"The purpose of this investigation was to determine the general geology of an unusually complex area containing several small mines and located in the northwest corner of Yuma County, Arizona. This report is the first attempt to work out in detail the lithology, structure, stratigraphy, petrography, and economic geology of the area"--Introduction, Purpose and Scope, page 1.

Construction Of A Capillary Viscometer And The Study Of Non-Newtonian Liquids, Hsun Kuang Yang

Masters Theses

"A capillary tube viscometer was built for the purpose of investigating the fluid properties of non-Newtonian aqueous CMC and Carbopol solutions. The viscometer was tested with Newtonian liquids (glycerine, water and two different oils) having known viscosities to insure that the viscometer was operating correctly. The shear stress-shear rate data obtained for different concentrations of CMC and Carbopol solutions were correlated using the simple power law model. The power law constants were only slightly affected by saturating the solution with iodine and carbon tetrachloride. Aging had very little effect on the viscosities of the CMC solutions but had a considerable …

Internal Friction Of Mixed-Alkali Silicate Glasses, James E. Shelby

Doctoral Dissertations

"The mixed alkali effect in silicate glasses was examined from internal friction measurements made over the temperature range from -190 to 500⁰C and at a frequency of 0.4 Hz. Supplemental measurements of the activation energy for the different internal friction peaks, dynamic shear modulus, density, and index of refraction were also made. All measurements were confined to silicate glasses containing mixtures of Li-Na, Li-K, Li-Rb, Li-Cs, Na-K, Na-Rb, Na-Cs, and K-Rb. Rötger's interpretation of the internal friction of mixed-alkali silicate glasses is shown to be incorrect. A previously unreported internal friction peak was observed whenever two different alkali oxides were …

Pair Distribution For A Cell-Model Liquid, James M. Phillips

Doctoral Dissertations

"The pair distribution function for a cell-model liquid has been derived by Lund in the form of an integral equation which depends upon the cell-center distribution function and the cell model. From this integral equation an approximate integral equation is obtained by substituting a function, which is linearly dependent upon the molecular pair distribution function and a variable parameter for the cell-center distribution function. This approximate integral equation is solved for the molecular pair distribution and the variable parameter is shown to depend upon the difference between temperature and the critical temperature. Although the exact numerical solution of the molecular …

The Microbial Hydrolysis Of Cellulose And Some Factors Affecting The Production Of Cellulase In A Submerged Culture Of Alternaria Sp, Robert Murray Logan

Doctoral Dissertations

"A mile hydrolyzing procedure was utilized to degrade oak sawdust. Its capability of producing a suitable fermentatation [sic] medium was studied. In the interest of solubilizing, enzymatically, the carbohydrate portion of oak sawdust, an investigation was conducted in which various microorganisms were examined for their ability to utilize different forms of cellulose for their growth and to produce cellulose decomposing enzymes. The microorganisms included a myxobacterium, several fungi, and a wood-rotting basidiomycete. The fungi included two highly cellulolytic organisms, Myrothecium verrucaria and Trichoderma viride. The myxobacterium used was Sorangium cellulosum and the basidiomycete was Pleurotus ostreatus. The principla substrates employed …

Drag Reduction In Newtonian Polymer Solutions, Harry C. Hershey

Doctoral Dissertations

"Prior work in the area of drag reduction has been mainly limited to aqueous solutions. Theoretical and empirical analyses of the resulting data in aqueous solutions have been hindered by the fact that some polymers cause drag reduction and others do not...This investigation was directed to the study of how the size and configuration of the polymer molecule in solution affected drag reduction and the related phenomenon of turbulence suppression. Apparatuses were designed and built to measure viscometric flow, curves, friction factors, velocity profiles, and normal stresses (by a jet thrust technique developed by Metzner and associates)"--Summary, page 1-2.

Zinc And Copper Content Of Stream Sediment In South-Central Missouri, Shih-Cheang Cheng

Masters Theses

"Thirty samples of stream sediment from the North Fork River, Bryant Creek and related tributaries in south-central Missouri have been analyzed for cold-extractable copper, cold-extractable heavy metal, total copper and total zinc.

Cold-extractable copper varies from 0 to 10 ppm and averages less than 1 ppm; cold-extractable heavy metal varies from 3 to 30 ppm and averages 12 ppm; total copper varies from 50 to 200 ppm and averages 88 ppm; total zinc varies from 20 to 300 ppm and averages 86 ppm.

The pH of the stream water appears to have no affect on the metal content of the …

A Second Study Of Homogeneous Nucleation Of Water Vapor In Helium, Raymond J. Schmitt

Masters Theses

"Absolute homogeneous nucleation rates in a supersaturated mixture of water vapor and helium are measured using a long sensitive time expansion chamber and a method devised by Kassner and Allard. A pulse technique is employed to produce the nucleation in an effort to suppress disturbing influences of vapor depletion and droplet growth. The time-varying nature of the supersaturation during the nucleation pulse is taken into account by an Integration over the pulse. Observed and theoretically predicted droplet concentrations are related by an assumed nucleation rate law which is adjusted until the total droplet populations predicted by integration of the assumed …
