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

Master's Theses

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 …

Fossil Bearing Basalts (More Particularly The Yakima Basalt Of Central Washington), George F. Beck

All Faculty Scholarship for the College of the Sciences

Such an overwhelming majority of the floral and faunal remains of the earth's crust have been yielded by rocks of sedimentary origin that generalized statements concerning the occurrence of fossils often neglect their more rare appearance in metamorphic and igneous rocks. In fact there is the temptation, after volcanic tuffs have been excluded as more or less sedimentary, to venture the positive assertion that by their very character igneous rocks are incapable of recording the presence of the life which may have existed at the time of their extrusion. As a result, most that has been written concerning fossil floras …

A Comparative Pollution Study Of The Domestic Water Supply Of Warren County, Kentucky, Glenn Scott

Masters Theses & Specialist Projects

The domestic water supply of Warren County, outside of the city of Bowling Green, is obtained from deep wells and springs. The county is about evenly divided into a southern section of cavernous limestone and a northern section of mixed sandstone and limestone formations.

The wells of the southern cavernous limestone region receive water from unfiltered underground streams and lakes. Most of the wells of the northern region are drilled in sandstone and the water, in a majority of cases, is filtered through porous sandstone and shale.

The purpose of this study was to make a comparative pollution study of …

Analysis Of Errors Made By 717 Collge Students In Arithmetic, O.D. Barnes

Masters Theses & Specialist Projects

During the greater part of the elementary-school training of the average American child he receives a large amount of instruction and drill in arithmetic. In the high school he suddenly drops arithmetic except as he maintains practices in courses of science or high school mathematics and except as the transactions of every day life involve arithmetic. In college the individual may suddenly find that the amount of arithmetical knowledge required is not small as in physics, chemistry or certain commercial courses. Evidence exists to indicate that students doing poor work in these courses are often found deficient in arithmetic.

Comparison Of Hydrogen Ion Concentration Results In Silicic Acid Gel Mixtures By Different Methods, Edward David Luneburg

Honors Theses

Since a conclusive theory of the structure of gels has not been presented yet, it is still necessary to obtain as much data about gels as possible, in the hope that the assembled data will lead to a theory which will explain all the known facts. Thus, the effect of such factors as temperature, concentration of acis and the addition of indicators were studied. Also, the change of the properties of viscosity and conductivity during the time of set were studied.

Change Of Conductivity Of Silicic Acid Gels Upon Setting, Robert Louie Slobod

Honors Theses

In the course of the investigation that has been conducted at Union College by Prof. Charles B. Hurd and his student assistants, it was soon found that something more accurate than the Wheatstone bridge would have to be used in measuring the electrical conductivity of gels. This becomes evident if we consider that in such studies we encounter the measurement of very small changes in the total resistance, changes of the order of one or two parts in twenty thousand. Accordingly, a modification of the Carey Foster bridge was developed for this work.

Migration Of Ions Through Silicic Acid Gels, Richard Edward Davies

Honors Theses

Ever since Liesegane (1), rediscovered the phenomenon of rhythmic precipitation first due to Runge (2), the colloid chemists have been using their ingenuity in attempts to explain the factors responsible for the formation of Liesegang rings. The theories resulting from such investigation have not been entirely satisfactory. In recent years the problem has been taken up by the students of waye mechanics in hope of conquering that which has so far defined the chemists. It is hoped that by continuing the work of Bieleski (3) and Rothemich (4) with the probing electrode, one of the many theories concerning the phenomenon …

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.

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.

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

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.

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.

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.

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 Purification Of Coffee Wax By Means Of A Special Extractor Followed By A Dialysis Process, John Dobrojevic

Bachelors’ Theses

This work was performed with the intention of devising a method where-by true wax could be isolated from a conglomerated mixture called coffee wax.

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.

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.

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.

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.

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.

Sensitivity Of Curcumin As An Organic Reagent In Testing For Beryllium, James W. Bookhamer

Bachelors’ Theses

For many years the analytical chemist avoided by design or more probably by accident the general use of organic chemicals in his work. Some few of them he accepted as a matter of course, and perhaps without much thought of their organic nature. In qualitative analysis he used chloroform as a solvent in testing for bromine and iodine. A few indicators were in common use, but organic chemicals were used but little in analytical work. It was not until the twentieth century that their use in analytical procedures received any worthwhile attention. Since then they have rapidly come to the …

Some Aldehyde Condensation Derivatives Of Creatinine, Clarence England Denoon Jr.

Master's Theses

When insulin, a substance which is used to reduce sugar in the blood is hydrolysed, products are obtained bearing some similarity to creatinine. Therefore, reasoning conversely, creatinine derivatives might be expected to posses as a hypo- glycemic (sugar reducing) effect.
