The Kinetics Of The Exchange Between Sn(Ii) And Sn(Iv) In Absolute Alcohol, E. Gerald Meyer

Chemistry and Chemical Biology ETDs

The radiochemical exchange reaction may in general be written AX+BX^• = +BX where X^• represents a radioactive atom of X. The species AX and AX^• are assumed to be chemically identical as are the species BX and BX^•. This assumption introduces no appreciable error even when working with atoms having an atomic weight as low as fourteen.

Some Reactions Of 4-Chlorocinnoline, F. H. Kruse

Chemistry and Chemical Biology ETDs

This problem involves the preparation of 4-chlorocinnoline by the method of Borshe and Herbert and Busch and Rast,^, and the study of further replacement reactions of the chlorine atom in the 4-position. The problem can be subdivided into two sections: (1) the preparation of the 4-cinnolyl Grignard reagent and the corresponding lithium compound and (2) the study of some condensation reactions of 4-chlorocinnoline.

An Analytical Study Of Berberine, W. Riley Mcgaughran

Chemistry and Chemical Biology ETDs

Berberine, an alkaloid, has unique pharmacological properties as well as unusual chemical and physical characteristics. This compound has been used for many years as a remedy for eye diseases. In contrast to most alkaloids, berberine hydroxide is more soluble than its salts. Its chemical structure has been established, but a correlations of many of its properties and its structures has not been made.

The purpose of this work was to undertake an analytical study of berberine, hoping to collect data which would make possible the correlation of certain properties of the compound with its structure. The study was planned to …

An Experimental Investigation Of Multivibrators, Harry W. Gates

Electrical and Computer Engineering ETDs

The object of this study is two-fold. The first part of the investigation is concerned with substantiating experimentally the mathematical analysis for the conventional multi-vibrator and to derive similar expressions for the grid return multi-vibrator. The second purpose of this investigation is to delve into several possible ways of improving the linearity and thereby the frequency division usefulness of the multi-vibrator.

The Ability Of Pupils In A Selected High School To Estimate Quantitative Measurements, Eugene W. Zylstra

Teacher Education, Educational Leadership & Policy ETDs

The purpose of this study is two-fold: (1) to ascertain with what degree of accuracy pupils of junior and senior level in a selected high school are able to estimate quantitative measurements; and (2) to determine whether or not the ability to make accurate estimates is related to such factors as mental ability, computational ability, or the amount of formal mathematics taken in high school.

A Study Of The Use Of The Dicyanatodipyridine (Ii) Complex For The Determination Of Cyanate, Jean Mcclelland

Chemistry and Chemical Biology ETDs

Treadwell states in his text, Analytical Chemistry, Volume II, that "the only method for examining cyanates consists in determining the amount of carbon and nitrogen present by combustion." A review of the available literature shows that, although this is not literally true, a procedure for this quantitative determination of small amounts of cyanates in the presence of interfering substances is lacking.

A survey of the literature yielded few references for instrumental methods for the quantitative determination of cyanates. Ripan-Tilici published a method for the determination of cyanates poteniometrically, but attempts to duplicate her work have failed. Madame Tilici, in …

The Syntheses And Ultraviolet Absorption Spectra Of 2-Imidazolines, 2-Imidazolidones And Imidazolidines, Robert J. Ferm

Chemistry and Chemical Biology ETDs

The first method used to prepare 2-imidazolines was through the reaction of aromatic aldehydes with ammonia. Amarin, which is known as 2,4,5-triphenyl-2-imidazoline, was the first compound reported to be prepared in this manner. This type of reaction has since been widely studied 2,3,4,5,6 in connection with the preparation of 2,4,5-triarylimidazolines. Furfural and ammonia have also been reported to react in a similar manner. Amarin has also been obtained from the reaction of a mixture of benzil, ammonia, and benzaldehyde.

A Study Of An Inverse Feed-Back, Low Frequency, Low-Pass Filter, Ralph A. Nobles

Physics & Astronomy ETDs

In connection with other research work in the physics department at the University of New Mexico it became of interest to make a detailed study of a resistance-capacitance couples low-pass filter which incorporate inverse feed-back. In order to determine the effect of the inverse feed-back on the filters, calculations are made on circuits with and without feed-back. Response curves are calculated for step-wave inputs and for sine-wave inputs, and these calculated curves then compared with experimental response curves.

A New Method Of Detecting Low Intensity Nuclear Radiation, Emerson Jones

Physics & Astronomy ETDs

In general there exist in the energy level scheme of many of the elements, transitions which give rise to the liberation of energy in the visible or near visible spectra. This situation gave rise to the hope that a gaseous element could be selected such that upon being excited or ionized by charged particle radiation, the predominant transitions to lower energy levels could be detected by photographic means. If a means of detecting these transitions could be made sufficiently sensitive, one could then hope to detect very low radiation intensities of charged particles. The problem consisted of evacuating a chamber, …

The Preparation And Properties Of Aromatic Ditellurides, Roger Sanftner

Chemistry and Chemical Biology ETDs

It has been shown that tellurium tetrachloride combines additively with aliphatic others yielding hygroscopic compounds of the type R2O•TeCl4, but with mixed ethers, containing both alkyl and aryl radicals, substitution takes place with the elimination of hydrogen chloride.

The Chelation Of Praseodymium As A Function Of Ph Using Thenolytrifluoroacetone, Thomas K. Keenan

Chemistry and Chemical Biology ETDs

The rare earth elements, including elements 57 through 71, provide many diverse series of studies through their chemical reactions. In as much as these elements are all in Group III of the periodic table, they are markedly similar in their properties. The separation, insulation and purification of the various rare earths from one another has long been a problem of great interest to the chemist. All of these elements show a principle valence of plus three. Cerium has a well-defined plus four state, stable in aqueous solution and europium forms a stable, insoluable divalent sulfate. Those two exceptions, however, are …

A Study Of The Lalande, New Mexico, Yonо̄Zu, Japan, And Glorieta Mountain, New Mexico Meteorites, Ralph G. Stevenson Jr.

Earth and Planetary Sciences ETDs

This thesis presents details relating to the discovery of three meteorites, as well as information concerning their acquisition, description, and mineralogy. These three meteorites are the Lalande, New Mexico chondrite (E.C.N. = 1047,343), the Yonо̄zu, Japan chondrite (E.C.N. = 1394,380), and the Glorieta Mountain, New Mexico siderite (E.C.N. = 1058,356).

The Lalande, New Mexico meteorite is composed of olivine and enstatite (var. hypersthene), with small percentages of enstatite-clinoenstatite intergrowths, secondary hematite, and dispersed metallic grains. Alteration to iron oxide has produced a strong stain over most of the component grains. The meteorite is classified as a hypersthene-olivine chondrite (Chy). …

A Study Of The Breece, New Mexico, Hishikari, Japan And Mino, Japan Meteorites, Louis H. Goldsmith

Earth and Planetary Sciences ETDs
