A Preliminary Study Of The Characteristic Physical Properties Of Chlorinated Asphalt, Ernest Clifford Spafford

University of the Pacific Theses and Dissertations

The introduction of chlorine into hydrocarbon compounds produces a product with properties markedly different from those of the original hydrocarbon. Methane, a gas at ordinary conditions, becomes methyl chloride, still a gas but having a higher condensation point than methane, upon the substitution of one chlorine atom in place of a hydrogen atom per molecule of methane. Upon the introduction of three atoms of chlorine per molecule of methane, chloroform, a very volatile liquid, is formed, and upon the introduction of four atoms of chlorine carbon tetrachloride, a less volatile liquid is produced.

Chlorination takes place in a “saturated” hydrocarbon …

A Study Of The Products Of The Reaction Between Stannous And Arsenate Ions In Silicic Acid Gels, Frank K. Thompson

University of the Pacific Theses and Dissertations

The fact that characteristic crystalline products result upon the diffusion of arsenate ions into silicic acid gel which has been impregnated with stannous ions has been known by the Pacific Chemistry Department for some time. The optimum conditions with regards to heat and hydrogen ion concentration have been determined. The purpose of this investigation was to study the products of the reaction. First to determine whether or not the silicic acid itself combined with the stannous and arsenate. ions in the formation of the crystalline product, and second to determine its chemical composition.

The Lime Content Of Rocks Of The Upper Cretaceous System Of Ellis County, Kansas, G. Lawrence Rarick

Master's Theses or Doctor of Nursing Practice

The report which is being submitted here is the result of several weeks of field and laboratory work investigating the rocks of the Upper Cretaceous System of Ellis County, Kansas. The writer has attempted to consider the subject primarily from a chemical viewpoint although much of the background for the work has been of a geological nature. There has been no attempt to give a complete chemical analysis of the rocks of the Upper Cretaceous System, but rather a more or less thorough analysis in regard to the percentage of lime that the rocks of the various formations and members …

A Metallurgical Study Of Gold Ores, Alfred A. Bloom

Bachelors Theses and Reports, 1928 - 1970

Gold is widely distributed in the earth's crust in small quantities. Gold is found in nature in two forms; the element itself and the compound gold telluride. In all cases, silver in some proportion is an alloying constituent.

Attempted Proofs Of The Differentiation Of Magmas By Syntexis, Clifford Wendel

Bachelors Theses and Reports, 1928 - 1970

This investigation was an effort to obtain proof of the much disputed principle that most of the observed mag­netic differentiations have been due to the assimilation, or syntexis, of the intruded country rocks.

The Effect Of Sodium Fluoride On The Bright Plating Range Of Chromium, Ernst Curschmann

Bachelors’ Theses

Chromium is used very extensively at the present time as an exterior plate over other metals. It has found favor not only because of its brilliant blue, untarnishable lustre, but also because of its extreme hardness. The great increase in the demand for chromium plate in recent years, rapidly relegating nickel plate into the background, has resulted in increased research and experimentation .in the field of chromium plating, in the endeavor to provide a lasting, beautiful plate at a minimum of expense.

Present chromium plating baths containing sulphuric acid as the active agent of deposition leave much to be desired …

E, Doyle K. Brooks

Master's Theses or Doctor of Nursing Practice

The meteoric splendor of the transcendental constant e is an intriguing mystery. It rises unexpectedly from nowhere, brilliantly illuminates some obscure mathematical concept, points to its solution, and abruptly fades into oblivion. Its unheralded visitation leaves the student wiser but wondering, tantalized by its omnipotence in apparently unrelated fields. Ever since his first introduction to e in elementary logarithms it has seemed to the writer that all the authors of textbooks are in a conspiracy to defeat any real knowledge of e. They say "2.71828… , called e, is the base of Naperian logarithms." Why? "The derivative of eX is …

Electrolytic Recovery Of Copper And Zinc From Brasses, Thomas Barker Jr.

Bachelors Theses and Reports, 1928 - 1970

Reclaimed metals, or secondary metals, are becoming of great im­portance in the metal industries of the world. Secondary metals are an important factor in production. The increase in the secondary production of copper is due to many factors. One of these may be its permenance, that is, the metal does not corrode very readily. Another reason for increase in production is the high price paid for it.

The General Geology Of The Cardwell Mining District, Clyde Congdon

Bachelors Theses and Reports, 1928 - 1970

The Cardwell Mining District is part of the greater Whitehall Mining District. The district is situated about four miles to the east and northeast of Whitehall in the southern end of the Bull Mountains which are near the Continental Divide. The first reported production was in 1896 after the dis­covery of the Mayflower Mine. Mining has been carried on in­termittently and on a small scale since that time.

The Electrodeposition Of Manganese From Certain Aqueous Solutions, Fred J. Hill

Bachelors Theses and Reports, 1928 - 1970

Careful examination of the literature available shows that the electrodeposition of manganese from various aqueous solutions has not been attempted to any great extent. The best method for the electrodeposition of pure manganese consists in the electrolysis of a solution con­taining manganous and ammonium sulphates.

Conductivity Applications, Henry W. Koch

Bachelors’ Theses

Since the introduction of Arrhenius’ theory of electrolytic dissociation more than forty years ago, many applications of the chemistry of electrolytes have been formulated. Of the many uses of conductance measurements, conductivity titrations have lately assumed the theoretical and technical importance which they rightfully should have. Conductance measurements enjoy prominence both in practice and in research, and the almost unlimited field provides a wealth of material for the ardent electrochemist. There is no doubt that many of the old analytic methods will soon be largely supplanted by this newer procedure which even at the present finds such varied usefulness.

The Staining Effect Of The Hydrochloric Acid-Chromate Trioxide Solution On The Minerals Of The Chalcocite-Stibnite-Galena Ternary System., John W. Johns Jr.

Bachelors Theses and Reports, 1928 - 1970

The object of this work has been to devise a method by which the different phases in the chalcocite-stibnite-galena ternary system may be identified. As the mineralogists have no precise methods for the identification of these phases, a hydrochloric acid-chromate trioxide staining solution was employed.

The Separation Of Tungstic Oxide From Scheelite And Its Subsequent Reduction With Hydrogen, Dave Jones

Bachelors Theses and Reports, 1928 - 1970

The largest known deposits of tungsten ores occur in the continuation of the Indo-Malayan Mountains, which extends through Burma, Malaya, China, Japan, and Chosen. Production of tungsten concentrates was started in 1910 in Burma, and in 1911 this country was the world's largest producer. China produced but little until 1916, but has since supplied over fifty per cent of the world's requirements.

Microscopic Study Of Montana Silver Ores., Edwin Johnson

Bachelors Theses and Reports, 1928 - 1970

A microscopic investigation of the Montana silver minerals was conducted. This study consisted mainly of identifying the silver and silver-bearing minerals and of determining their paragenetic rela­tionships. The increasing amount of research in which the reflecting microscope is employed is evidence of the great value of this method of approach in the solution of problems of paragenesis of the opaque minerals.

The Geology Of Lost Creek Canyon With Special Reference To Igneous Activity, John Kolesar

Bachelors Theses and Reports, 1928 - 1970

This investigation was undertaken primarily as a problem in geologic mapping, coupled with a study of stratigraphy, glaciation, igneous phenomena, and structure. The area is admirably suited to a study of geology and geologic events. Because it is small in extent, the area was studied in some detail during the time which was devoted to field work. The record of igneous activity of past geological ages is re­markably well exposed, since Lost Creek Canyon was carved through the roof of a stock or batholith by the glaciers of the Pleistocene epoch.

Occurrence And Origin Of Placer Gold In Montana, John K. Halse

Bachelors Theses and Reports, 1928 - 1970

From time immemorial man has used gold as a medium of exchange, a mea­sure of value, as jewelry and for ornamentation. Placer gold has led dir­ectly or indirectly to the settlement of lands, California and Alaska being the two best known examples. It has led the way to the discovery of other important mineral wealth, the discovery of the copper and silver deposits at Butte, Montana and the discovery of the silver deposits at Cripple Creek, Colorado being two good examples.

A Preliminary Study Of The Ostracoda Of The Big Snowy Group, Mississippian, Of Montana., John C. Rabbitt

Bachelors Theses and Reports, 1928 - 1970

In the field, samples were taken vertically and horizon­tally along the various outcrops in different sections of central and south-central Montana. At important localities the samples were taken about every half-foot verti­cally; in other sections they were taken every few feet.

An Investigation Of The Properties Of Some Of The White Metal Alloys, William James Walsh Jr.

Bachelors Theses and Reports, 1928 - 1970

Although there is no standardized list of alloys, most investigators have, to avoid confusion, concurred in at least grouping the metals under several general heads. Precious metals: gold, silver and the platinum group; the light metals: aluminum and magnesium; the non-ferrous metals (excluding all steels and iron-base alloys); and the antifriction metals.

Siliceous Sponge Spicules Of The Quadrant Formation From Montana., Lester Zeihen

Bachelors Theses and Reports, 1928 - 1970

A sponge spicule is a siliceous or calcareous individual or group of rays which form a framework for the sponge. Sponge spicules are very delicate and easily broken. The methods used in obtaining micro-fossils vary considerably with the type of material from which they are to be recovered and the frailness of the fossil obtained.

The Preparation Of Calcium And Barium Gluconate, Ronald Anthony Plzak

Bachelors’ Theses

The privilege of working on this subject is one which the author has sincerely appreciated, as it has given him the opportunity of incorporating many of the more recent contributions along the line of oxidizing aldose sugars. In reviewing these contributions, he has abstained from conveying an impression of finality and has attempted to show the many possibilities which the free sugar acids offer for the future. The experience of the last few years has proved that even long-cherished conceptions and apparently well-established facts may at any time undergo drastic revision. For this reason, the author has referred directly to …

Solution Of The Equation: Y1 = (Ax2 + Bx + C)N (Kx + L), Edith Florence Mayer

Bachelors’ Theses

The general solution of an ordinary differential equation of the n^th order is one that involves n arbitrary constants* Although the general solution may assume a variety of forms. all of these give the same relation among the variables, so that actually there is only one general solution.
