The Anodic Dissolution Of Zinc In Aqueous Solutions, Glenn E. Stoner

Masters Theses

"The increasing demand for protective metals as coatings and non-corrosive alloys has stimulated extensive research on the fundamental behavior of metals in corrosive media.

One of the problems still unsolved is the nature of the mechanism of the anodic dissolution of metals like zinc, magnesium, beryllium, cadmium, and aluminum in aqueous salt solutions. Several schools of investigators have proposed different and opposing theories to explain the discrepancies which often arise between coulometric data and the weight loss of metal electrodes in certain salt solutions.

The purpose of this investigation was to obtain experimental data for the anodic dissolution of zinc …

Hydrogeology Of Reservoir Sites In The Meramec River Basin, Missouri., John H. Anderson

Masters Theses

"Governmental and private agencies have proposed construction of multiple purpose dams in the Meramec River Basin for flood control, conservation, recreation and possible power development. Evaluation of the effects of reservoirs created by these dams on ground water conditions has not been published. Study of possible effects led to the thesis that prediction of changes in ground water conditions could be made.

Several limited applications of ground water geology techniques to the problem of reservoir-ground water relations were studied; no thorough previous studies were found. Apparently, complete studies have not been undertaken by even the larger agencies.

Inspection of the …

Mathematical Techniques In The Solution Of Boundary Value Problems., Vincent Paul Pusateri

Masters Theses

"This study was undertaken to present a summary of mathematical techniques as applied to the solution of boundary value problems in partial differential equations.

The techniques that were presented can be considered to be some of the most popular in applied science.

The salient features of the study are that different techniques can present different analytical expressions for a solution to the same boundary value problem, and from the viewpoint of computation and accuracy one solution may prove more desirable than the other.

The study also indicates that in boundary conditions where finite discontinuities exists, a slight perturbation to remove …

Pegmatites Of The Anderson Ridge Quadrangle, Fremont County, Wyoming, Hassan A. Etr

These have been intruded in the northern part of the area by a batholithic body of granitic composition, a granitic stock, a pegmatitic granite, a granitic sill-like body and different types of pegmatite dikes and sills. The youngest intrusions are a series of northeast trending basic dikes and sills. A major easterly trending transverse fault and a series …

Hydroxy Derivatives Of Benzalthiophenone, John M. Newey

University of the Pacific Theses and Dissertations

It is the purpose of this work to prepare a series of these chalcones containing the thiophene ring.

The compounds were prepared by the condensation of a series of benzaldehydes with acetylthiophene dissolved in dry ethylacetate and saturated with dry HCl. The benzaldehyde compounds were benzaldehyde, m-hydroxybenzaldehyde, o-hydroxybenzaldehyde, O-p-dihydroxybenzaldehyde and vanillin. To prevent the oxidation of the hydroxy groups of the benzaldehydes, the compounds were benzolated with benzoylchloride. The condensed products were debenzoylated with NaOH solution in an atmosphere of nitrogen to prevent oxidation during the debenzoylation process.

The Diagenetic Origin Of The Dolomites, Chert, And Pyrite In The Jefferson City Formation., Erik Hans Schot

Masters Theses

"Diagenesis designates all modifications which a sediment undergoes during and following deposition and prior to complete lithification, metamorphism, deep burial, and orogenesis.

Probably the dolomites of the Jefferson City Formation resulted from alteration at, or below the sea floor or the depositional interface and during diagenesis. Diagenetic dolomitization or penecontemporaneous alteration presumably involves a reaction between the calcium carbonate sediments at/or below the sea floor or the depositional interface and magnesium salts in solution or suspension in the basal layer of contacting sea water, or in the initial pr connate water trapped in the sediment.

The cherts of the Jefferson …

The Measurement Of The Life-Time Of The 62P3/2 State Of Thallium, Danny Hale Sokolowski

Masters Theses

The measurement of the lifetime of the metastable 6²P_3/2 state of thallium is discussed. Time-sampling equipment techniques and instantaneous methods of display on an oscilloscope for measuring the lifetime are explained. The lifetime is measured as a function of mercury vapor pressure. The decay of the 5350 A thallium line is also measured to give an indication of the effect of the imprisonment of the 3776 A resonance line. This decay of the 5350 A line is also in a mercury atmosphere"--Abstract, page ii.

Fossil And Recent Beryciform Otoliths: An Adjunct To Ichthyological Classification., C. Kurt. Lamber

Masters Theses

Of three pairs, only the taxonomically important earstones (sagittae) are considered here. Specifically, this study is restricted to the sagittae of beryciform fishes (Order Beryciformes). Removal of some taxa from the order, and the possible relating of others, is suggested.

The morphology of beryciform sagittae is described, and three basic supra-familial groups are recognized. Diagnostic characters for families are given, with diagnoses of genera added. Sagittae of characteristic species are illustrated.

Otoliths of fossil beryciform fishes, as known from specimens and published illustrations, are …

Permeation Of Water Vapor Through Linear Polymer Films, Mohammed S. Rifai

Masters Theses

"Film formation from thermoplastic resin solutions Is Influenced by secondary intermolecular forces. Consider what may happen when organic coatings change from a liquid to a solid state. In the liquid state it is logical to consider the linear polymer molecules as agglomerates being dispersed in the volatile component rather than being present In solution. These molecular agglomerates are referred to as micelles. They have various degrees of orientation depending on the extent and the location of dipole forces in both polymer and solvent molecules.

When a coating is applied the solvent starts to evaporate and the micelles are driven closer …

Kinetic Investigation Of The Hydrochlorination Of Olefins In Aprotic Solvents And Sulfonation Of Idobenzene And The Selectivity Relation, Thomas Glen Davies

Theses and Dissertations

Kinetic investigation of the hydrochlorination of cyclohexene and cis-2-butene in n-heptane with SnCl4 as catalyst shows that the reaction is second order with respect to both olefin and catalyst. The specific rate constants at 25° , 0° and -23.8°C and the activation parameters were determined. Investigation of the Ga2Cl6 catalyzed hydrochlorination of cyclohexene and cis-2-butene in dichloromethane indicates that alkylation and polymerization compete with the hydrochlorination reaction in the presence of the solvent. The relative reaction rates and the isomer distribution for the sulfonation of iodobenzene by S35O3 have been determined in refluxing SO2 at -10°C. The reaction resulted in …

Sulfonation Of Chlorobenzene And The Selectivity Relation ; Bromine Addition To Cyclohexene In Dichloromethane ; Thorpe's Synthesis Of The Caged Acid, 4-Methyltricyclo[1.1.0.0[Superscript 2-4]] Butane-1,2,3-Tricarboxylic Acid, John A. Gurney

Theses and Dissertations

Aromatic sulfonation and some substitution reactions of chlorobenzene show deviations in the selectivity relation. A determination of chlorobenzene sulfonation provided the following rate ratio relative to benzene and partial rate factors: 1.0, [---] of 0.064 , mf 1.7 and pf 4. 2. Our work, Olah's nitration, Ferguson's bromination and Stock's chlorination define a new relation that can be express by adding an entropy term (A) to the selectivity relation. We determined the rate of bromine-cyclohexene addition in dichloro-methane at 0° to provide a basis for a systematic variation of solvents at low temperature. An unusual zero-order reaction was encountered. The …

Dissertation In Organic Chemistry. Part I, The Fate Of The Anilino Moiety In The Rearrangement Of Α-Anilonoketones. Part Ii, Partial Rate Factors For Sulfonation Of Bromebenzene With Sulfur Trioxide. Part Iii., Preliminary Survey On The Effect Of High Pressure On Ferrocene And Cycloöctatetraene, Jerold Carter Robertson

Theses and Dissertations

Part I. The rearrangement of α-anilinoketones was studied in an effort to determine the mode of movement of the nitrogen moiety. A crossover experiment was carried out with an equimolar mixture of 2-(4- bromoanilino)-1-(4-bromophenyl)-2-(4-methoxyphenyl) ethanone and 2-(4-chloroanilino)-1-(4-chlorophenyl) -2-(4-methoxyphenyl)ethanone with γ- picoline hydrobromide as the catalyst. The reaction product was analysed by means of a mass spectrograph. The results of the analysis indicate a crossover of the nitrogen moiety during rearrangement. This indicates that the nitrogen moiety moves in an intermolecular manner during the rearrangement. Part II. The isomer distribution from the sulfonation of bromobenzene with sulfur trioxide was determined by …

Geology Of The Sedillo-Cedro Canyon Area, Bernallio County, New Mexico, Bert Norman Brown

Earth and Planetary Sciences ETDs

This report was undertaken primarily as a study of Pennsylvanian strata which crop out in the Sedillo-Cedro Canyon area. The subdivision of the Madera formation as proposed by Read and others (1944) was adopted for purposes of mapping. This subdivision is based on a dominance of either limestone or clastic rocks in the formation.

The writer was unable to measure a Pennsylvanian section in the field due to thickness changes, facies gradations, and faults which were often concealed by dense soil cover. However, by visually traversing the area on aerial photographs using arbitrarily chosen zones, estimated thicknesses for the members …

The Time Required For Nuclear Fission, William Earn Stein

Physics & Astronomy ETDs

The present work is concerned with the mean lifetime of compound nuclei formed in the fast-neutron-induced-fission process. A new method for the measurement of these lifetimes is proposed. The present method is based on the recoil of the compound nucleus following neutron capture and the secondary electrons emitted by fission fragments. Previous experimental and theoretical work concerning the secondary electron yields for fission fragments and other charged particles are reviewed. The importance of the higher energy electrons, the so-called delta rays, formed in the primary ionization process is considered. The subsequent secondary ionization produced by these delta rays provirles a …

The He3 + T Reactions., Darryl B. Smith

Physics & Astronomy ETDs

The energy distribution of the alpha particles and of protons frim the He3+ t reactions have been measured for 1.9-Mev incident tritons at laboratory angles of 30° for alpha, and both 30° and 90° for protons. Absolute cross selections are obtained. The spectra are discussed in terms of a model which assumes that uncorrelated three-body breakup and several two-stage processes all contribute independently to the cross section. The calculations based on this model are in excellent agreement with the observed spectral shapes. The neutron-proton correlation corresponding to the unbound singlet state of the deuteron is observed. The binding energy of …
