The Magnetic Monopole, Thomas E. Kemple
The Magnetic Monopole, Thomas E. Kemple
Masters Theses
"Since Dirac has shown that the concept of a magnetic monopole follows from the fundamental laws of quantum mechanics and that it imposes quantization of electric charge, one has reason for taking the magnetic monopole seriously. Such particles, if they exist, would also give symmetry to Maxwell's equations.
A comprehensive review of the literature is presented and all known properties of magnetic poles are discussed. Scattering of mono- poles by heavy nuclei is analyzed in detail and definite mathematical relations are established. All previous experimental work known is outlined and discussed. Definite criteria for identification of monopole tracks in a …
Geology Of The East-Central Portion Of The Nelson Quadrangle, Clark County, Nevada, Tedral Kantor
Geology Of The East-Central Portion Of The Nelson Quadrangle, Clark County, Nevada, Tedral Kantor
Masters Theses
"The purpose of this investigation was to determine the unusually complex geology of a little-known area south of the Eldorado mining district, southern Clark County, Nevada. The area, mapped at a scale of 1:24000, comprises a segment of the northerly-trending Eldorado mountains in the southeast corner of the Great Basin. This rugged desert area is on a drainage divide between the Great Basin and the Colorado River. The rocks of the area consist of Precambrian gneisses and schists invaded by successive generations of Upper Cretaceous (?) - Tertiary igneous rocks. The older rocks, mainly biotite-chlorite gneisses, have resulted from high-grade …
Certain Features Of Alteration In The Michigan Lavas And Their Genetic Interpretation, Peethambaram Doraibabu
Certain Features Of Alteration In The Michigan Lavas And Their Genetic Interpretation, Peethambaram Doraibabu
Masters Theses
"The origin of the alteration and copper mineralization in the Keweenawan lavas of the Upper Peninsula of Michigan is one of the well known controversial topics in Economic Geology. The literature on this problem is most extensive and an attempt was made in this thesis to first review as many aspects of the discussion as appeared to be necessary. This portion is necessarily extensive, and it is hoped that some new light has been thrown here on some patterns of approach or thought which, today, can hardly be called scientific.
Next, the observations made in the field, on hand specimens …

The Surficial Geology Of Southern Logan County, North Dakota, John W. Bonneville
The Surficial Geology Of Southern Logan County, North Dakota, John W. Bonneville
Theses and Dissertations
Southern Logan County, North Dakota, was glaciated at least three different times during the Pleistocene epoch. Scattered patches of highly weathered iron-cemented drift found in the area of eroded Cretaceous bedrock in southwest-era Logan County are very possibly pre-Wisconsinan in age. Two younger drift sheets of Wisconsinan age cover the remaining portion of the county. One of these drifts, the Napoleon drift, is probably early Wisconsinan, and the other, the Burnstad-Streeter drift, is likely late Wisconsinan in age.
A great diversity in types of glacial topography and individual features is found in southern Logan County. Excellent examples of end moraine, …
An Experimental Investigation Of Coloring Matter In Canna Indica Flowers, James Clinton Vogt
An Experimental Investigation Of Coloring Matter In Canna Indica Flowers, James Clinton Vogt
University of the Pacific Theses and Dissertations
The research was carried out for the purpose of isolating and identifying the coloring matter in flowers of the canna indica (canna lily) variety. It was done by extracting the pigment from flower petals with methanol, amyl alcohol, and other solvents, and crystallizing the pigment as a salt. Physical properties such as solubility, color reactions, spectra and others were examined for this pigment. Chemical properties and degradation products were also examined in order to identify the chemical structure of the pigment.
A Kinetic Study Of The Base Catalyzed Esterification Of Propionic Anhydride With Isopropyl And N-Propyl Alcohols Using A High Frequency Oscillometer, Carl Joel Abraham
A Kinetic Study Of The Base Catalyzed Esterification Of Propionic Anhydride With Isopropyl And N-Propyl Alcohols Using A High Frequency Oscillometer, Carl Joel Abraham
University of the Pacific Theses and Dissertations
The purpose of this research project is to investigate the base catalyzed reaction of propionic anhydride with n-propyl and isopropyl alcohols using a high frequency (120 megacycles) oscillometer to follow the course of the reaction as it proceeds.
The high frequency oscillometer has been used for many types of analytical determinations, and a review of the work up to 1957 is available in a publication by E. H. Sargent Company. The oscillometer has found application in titrations (Hall 1952), analysis of binary systems (Thomas, Faegin, and Wilson 1951) , static ternary systems (West, Robickaus, and Burkhalter 1951) , the study …
The Carbon Compounds Of The Primeval Atmosphere, James Sherman Rogers
The Carbon Compounds Of The Primeval Atmosphere, James Sherman Rogers
University of the Pacific Theses and Dissertations
The question of how and when life originated on t his planet has always been an intriguing one, exceeded perhaps in fascination only by that area of speculation which concerns itself with death and the afterlife . The latter problem has generally been approached along theological lines; the former problem , that of the origin of life, has been widely investigated along scientific lines as well . Indeed, the origin of life has always been one of the fundamental problems of science, and the increasingly sophisticated answers to the problem reflect the increasing potence and applicability of the methods of …

Construction And Calibration Of Equipment For Obtaining Heat Capacity Data At High Temperatures, David Wells Wood
University of the Pacific Theses and Dissertations
This is a study of the heat capacity substances at high temperatures at determined by means of drop-calorimetry. The heat capacity may be defined as the quantity of heat required to raise the temperature of a substance by 1o C. This can be expressed as [see PDF file for formula]. The concept of heat capacity is used in connection with a certain defined path such as those of constant volume or constant pressure. The following definitions apply: [see PDF file for formula] = heat capacity at constant volume and [see PDF file for formula] = heat capacity at constant …
Cosmology And Galactic Angular Momenta, Marmion Michael Richard Hays
Cosmology And Galactic Angular Momenta, Marmion Michael Richard Hays
University of the Pacific Theses and Dissertations
The plan of this paper is to present some observations and then in subsequent chapters to examine the two basic cosmological ideas in the light of these observations.
The first of the observations involves an estimate of the angular momentum in a given volume of space and the ratio of this momentum to the mass or number of nucleons in the given volume. We therefore wish to obtain a rough estimate of the angular momentum in that part of the universe which man may call his immediate surroundings, i.e., the solar system and galaxy.

Identification Of The Products And Mechanism Of Decomposition Of Thiazate, Paul Edward Williams
Identification Of The Products And Mechanism Of Decomposition Of Thiazate, Paul Edward Williams
University of the Pacific Theses and Dissertations
This work is an additional facet of the research undertaken by Dr. Herschel Frye of the Department of Chemistry of the University of the Pacific while he was a graduate student at the University of Oregon. Frye succeeded in making an analytical reagent for zinc and other transition metals similar to dithiszone but water soluble. His approach was to to sulfonate the benzene rings thus giving water solubility because of the ionic nature of the sulfonic acid. The new reagent-tensed thiazate--was quite successful in its purpose, but the sections of the compound were somewhat different than dithizone. The purpose of …

The Determination Of Ethanol In Aqueous Solution By Gas-Liquid Partition Chromatography, Robert L. Morrison
The Determination Of Ethanol In Aqueous Solution By Gas-Liquid Partition Chromatography, Robert L. Morrison
University of the Pacific Theses and Dissertations
The present chemical and physical methods for the determination of ethyl alcohol are all subject to systematic errors derived from any of a number of interfacing substances usually present in solution with the ethanol. Some of the most popular methods are slow and tedious and require a good deal of skill and technique to perform. The dichromate (2), pycnometer and refractometer methods are three such methods. The interfering substances most often present in industrial and food products are fusel oils and acetaldehyde. These substances interfere in the three methods just mentioned. It is of course possible to analyze for these …
Analysis Of The A3(X3)3 Nuclear Spin System And -Electron Coupled Hyperfine Splitting Constants In Aromatic Hydrocarbons, Juana Acrivos
Analysis Of The A3(X3)3 Nuclear Spin System And -Electron Coupled Hyperfine Splitting Constants In Aromatic Hydrocarbons, Juana Acrivos
Faculty Publications, Chemistry
The nuclear spin functions for the A3(X3)3 system have been developed and used to analyse the NMR spectra of (CH3)3C6H3 and (CF3)3C6H3. The π-electron coupled hyperfine splitting constants, obtained from the Ramsey theory with simple Hückel M.O.'s for benzene and without the assumption of an average energy of excitation for the virtual processes which give rise to the coupling, are in agreement with the hyperfine constants observed between the methyl groups and the ring protons in the above compounds.
