The Effects Of Ultrasonic Vibration, Tension And Torsion On The Charge Acceptance Of The Alkaline Silver Electrode ; Ii. Potentiostatic Studies Of The Oxide Growth Rate Law For The Alkaline Silver Electrode ; Iii. The Determination Of Ionic Transport In Silver Oxide Using Radiotracer Techniques With Ag[Superscript 110m], Reed Harold Chase

Theses and Dissertations

The effect of ultrasonic vibration on the anodic oxidation of silver foil in KOH was studied. An increase in charging capacity of approximately 20% was found to be the result of cavitation erosion. Silver wire was exposed to tension and torsion during oxidation but no change in charge acceptance was caused by these stresses. The oxide growth rate on silver foil electrodes was compared to rate equations that have been proposed for other metals. Uhlig's equations for the growth of semiconductor oxides was found to describe most of the data. The data did not fit other rate equations. Determination of …

A Study Of Selected Photo Fries Rearrangements, Elwood Lloyd Loveridge

Theses and Dissertations

The Fries rearrangement of phenyl esters is reviewed and compared to the reaction when light is the source of energy. The products are different due to different mechanism of reaction. Light energy causes either free radical or concerted reactions. The S-phenylthiol esters and anilides were studied also. Although many of the rearrangements are the same, we did not see any alkyl migration nor decarboxylation type reactions with either the sulfur or nitrogen compounds. Three papers have been published from this work: Bradshaw, J. S., Knudsen, R. D. and Loveridge, E. L., J. Org. Chem., 35, 1219 (1970); Bradshaw, J. S., …

Spatial And Temporal Partitioning Between Sympatric Rodents: Zapus And Peromyscus, Emma Bernice Speer

Theses and Dissertations

Partitioning space and time by seemingly sympatric rodents, Zapus princeps and Peromyscus maniculatus, were examined as possible mechanisms allowing coexistence. The two populations were studied in Central Utah with an electrically monitored grid. Spatial separation of individuals and the populations minimized confrontations and created local allopatric distribtuions. Temporal partitioning was not used as a mechanism to allow coexistence and was apparently independent of spatial partitioning. The Peromyscus population was composed primarily of males which may have been due to less favorable habitat and/or presence of Zapus. The data show that Peromyscus tend to avoid Zapus, possibly due to deleterious aggressive …

Voltammetric And Electrochemical Kinetic Studies Of The Halides And Halogens At A Platinum Rotating Ring-Disk Electrode In Anhydrous Acetic Acid, Donald Harrison Cranney

Theses and Dissertations

The electrochemical behavior of the iodine-iodide couple was investigated in both basic and neutral acetic acid solutions at a platinum rotating ring-disk electrode. Voltammetric curves were obtained and discussed. Various kinetic parameters were determined and by comparing to theoretical kinetic parameters a probable reaction mechanism was deduced. The mechanism that best fit experimental results is the following I- + S = I(S) + e- I(S) + I- = I2 + S + e (slow). The electrochemical behavior of bromine, bromide, and chloride was also investigated in the same media. Voltammetric curves were recorded and discussed with emphasis on the hysteresis …

The Glacial Geology Of Mckenzie County, North Dakota, Clark Fulton

Theses and Dissertations

Fourteen lithostratigraphic units composed of windblown, glacial, lake, slopewash, and stream sediment were distinguished in McKenzie County, The units were mapped using aerial photographs, topographic maps, and soil maps combi11ed with field e:xaminations of sediment outcrops. Eight of the units have been formally named and described in earlier studies. Four of them, however, have not been a"~ previously named and formally described .a.nu assigned names in this study. Two other units are described, but because of their limited exposure, are not assigned a formal lithostratlgraphic name. The oldest sediment exposed in the county was deposited during the Paleocene and the …

The Attribution Of Fault To Rape Victims: Subject Variables Affecting Blaming, Stephan Podrygula

Theses and Dissertations

This study investigates the subject variables involved in the attribution of fault to rape victims. A consideration of attribution theory, in particular Heider's "naive analysis of action," suggests that innocent victims of misfortune will be blamed, however implausible this at first seems. Heider's theory has led to two specific theoretical explanations for blaming, E. Walster's defensiveness hypothesis and Lerner's just world hypothesis, both of which are examined in some detail. The relevant theoretical and experimental literature is reviewed, an assessment of the current standing of these explanations is made, and unresolved issues are raised. Several issues and questions based on …

The Intermolecular Potential And Vibrational Relaxation Of The Ar-Co System, Gregory Allen Parker

Theses and Dissertations

The angle, distance and vibration dependence of the Ar-CO intermolecular potential is calculated using the electron gas model to obtain the short range interaction which is smoothly joined onto the long range van der Waals tail which is obtained from accurate C_6, C_7, and C_8 coefficients. Our calculated second interaction virial coefficients are compared with experiment and with a simple adjustment of the Ar-CO potential an excellent agreement is obtained. Our spherically averaged potential is also in excellent agreement with a spherical potential inferred from high energy scattering data. Simplified expressions for the scattering amplitude and differential cross section are …

A Potentiometric Method, A Convenient And Rapid Technique For Determination Of The Thermodynamics Of Ionization Reactions For Water, Weak Acids, And Some Slightly Soluble Salts In Aqueous Organic Mixed Solvents, Charanai Panichajakul

Theses and Dissertations

A potentiometric method which is devised to be rapid and convenient for determining ionization constants for water, weak acids (or bases), and certain solids in mixed solvents is described. The method has been applied to the determination of ionization for water, acetic acid, benzoic acid, and phenol and the solubility product constant for silver chloride in mixtures of water with methanol, ethanol, acetone, tetrahydrofuran, and p-dioxane containing from 0 to 70 mass percent organic co-solvent at several temperatures between 10 and 40°C. Results are used to study the thermodynamics of ionization in each mixture which is discussed relative to various …

Experiential Learning: Theory And Postulates As Reflected In John Dewey's Theories Of Learning And Experience, Gary Gus Wegner

Theses and Dissertations

There is a need to integrate the experiences that take place through in-school activities and the exper snces that take place elsewhere in orde' to make the si nts1 learning more educative. This can be accomplished through the velopment and implementation of experiential learning programs within the school setting.

Solid-Liquid Phase Equilibria In Systems Of (I) Para-Xylene, (Ii) Mesitylene, And (Iii) N,N-Dimethylformamide ; Excess Volume Determination In Systems Containing Cyclohexane ; Calculations Of Activities For The N-Hexane + Cyclohexane System, John F. Moellmer

Theses and Dissertations

Solid-liquid phase equilibria studies were used to investigate possible compolllld formation in solutions of (i) para-xylene, (ii) mesitylene, and (iii) N,N-dimethyl-formamide (DMF) with mono- and di- halobenzenes that were selected to give a wide range of acceptor properties. Solid 1:1 intermolecular compounds were identified from solutions of p-C_6H_4F_2 with mesitylene, p-C_6H_4Br_2 with p-xylene, and p-C_6H_4Cl_2 with p-xylene. The results suggest that compound formation occurs because of favorable geometry rather than a charge transfer process. A vibrating tube densimeter was used to determine, with high precision, the densities and subsequently excess volumes of mixing of the n-hexane plus cyclohexane system. Temperature …
