The Summation Of The Series X+X/4+X/9+...+X/N-+.., William J. Nee

Bachelors’ Theses

The purpose of this thesis is to determine the sum of the series x+4²/4+x³/9+x⁴/16+....xⁿ/n². In order to determine whether or not the series is summable, we must first find out if it is a convergent series and so the first part of this paper will deal with some of the tests of convergence. After this matter is settles, we shall select a value of x, in this case x=1 and determine the ^∞∑/1 1/n2

The Geology Of The Southern Central Portion Of The Morrison Cave Area., Arthur Talpt

Bachelors Theses and Reports, 1928 - 1970

Morrison Cave is located about 50 miles southeast of Butte, Montana. It was named after the man who discovered it. Later it was taken over by the State and renamed Morrison Cave State Park. Recently the government with the aid of the Civilian Conservation Corps has built a new road to the cave and has made the interior more accessible. The name of the cave is now Lewis and Clark Cavern National Monument.

A Mechanical Analysis Of The Oriskany Sandstone In Northwestern Virginia, Selma G. Hirsh

Honors Papers

The primary purpose of this paper is to present specific data as a means of explaining the sedimentation conditions at the time of deposition of the Oriskany Sandstone. The data were obtained through the use of laboratory methods upon specimens taken from several outcrops in the vicinity of Monterey, Virginia (see Darton's U.S.G.S. folio No. 51). In addition to the presentation of objective results, the author has attempted to make tentative interpretations of them, based primarily upon textural and shape analysis of the sediment. The writer realizes that the investigation is inadequate in many respects, due to lack of time …

Preparation Of Thianthrene, Eugene Alton Talley

Master's Theses

This work was begun in an attempt to study further the preparation of thianthrene from 2-dichlorobenzene and alkali sulfides. g_-Dichlorobenzene is a liquid by-product in the preparation of its solid isomer, E-dichlorobenzene, which is used extensively for controlling moths and peach tree borers. The study of the preparation of thianthrene from the liquid isomer was undertaken because the preparation might develop into a possible use for the large quantities available.

Thianthrene might be made from 2-dibromo- and 2-diiodo-benzene but these are not as cheap or as easily obtained as the dichloro derivative and were not used in this study various …

The Catalytic Vapor-Phase Hydrolysis Of Benzene And Toluene, Clemens Raebel Maise

Masters Theses

"The vapor-phase synthesis of organic compounds represents a new field of study which has attracted the attention of investigators only within recent years. However, wide interest is apparent in this field and several processes of commercial importance have already been developed. Hydrolysis is perhaps the newest of all the types of vapor-phase synthesis; the literature consists of little more than a few patents...The vapor-phase hydrolysis of benzene and toluene, therefore, presented an interesting possibility. These two hydrocarbons are considered very stable toward water in the liquid-phase. The purpose of this investigation was to determine to what extent their stability toward …

Graphical Representations Of Singular Solutions Of Differential Equations, Kathryn Lois Pitman

Bachelors’ Theses

The first men to detect singular solutions of differential equations were Leibniz, Brook Taylor and Clairaut. The direct method of attack used by each man in attaining these solutions is not known, but a short history of each man and what he has contributed to mathematics can be given. Gottfried Wilhelm von Leibniz (1646-1716) was born in Leipsic, Germany, and was the son of a professor of law in a nearby university. He was well-educated in law himself, expecting to follow in the profession of his father. But not being under the necessity of earning his living, he enrolled at …

Corrosion Of Aluminum In Alkaline Solutions, George Oliver Doherty

Bachelors’ Theses

Aluminum has been an important member of the metal group since its isolation about 100 years ago. It has sprung into prominence in the commercial field and in household use in the last thirty years. The metal is light, possesses good thermal and electrical conductivity and as an alloy with other metals takes on a surprising degree of strength.

The problem of producing aluminum cheaply enough to make it practical has finally been overcome to a great extent. It now remains to be seen just what further uses there are to which this new metal may be put. Aluminum may …

The Paleozoic Stratigraphy Of Lorain County, Ohio, Edwin Hugo Wenberg

Honors Papers

During the course of the school year 1936-37 spent at Oberlin, which is situated near the center of Lorain County, Ohio, the writer had the opportunity to study the outcrops and to gather records of wells in this area.

A study of the strata of this county is confusing because the same rocks have been described under different formational names. Originally many of these strata were traced northward from type sections in central Ohio or westward from type sections near Cleveland. At a later date many of the strata were reclassified and assigned to formations which had been traced westward …

Oil And Gas Resources, Jackson County, Missouri, Joseph Robinson Clair

Masters Theses

"The oil and gas production in Jackson County, though rather small, is nevertheless of considerable economic importance. A portion of the county has been rather thoroughly developed but the remainder has had little prospecting. In order to aid further development in the region the Missouri Geological Survey engaged in the mapping of all the known wells in the county as a basis for preparing a structural contour map of the area. In addition, a member of the Survey staff is stationed permanently in Kansas City to give assistance to the operators in the region and to collect the logs of …

A Brief Consideration Of The Different Methods Of Integration, Donald Golden

Master's Theses or Doctor of Nursing Practice

Any student of mathematics is familiar with the importance of the process of integration. Integration is as fundamental to analysis as the basic principles of the number theory are to arithmetical calculation. Some of the common applications of integration are, finding the distance a falling body has travelled during a particular interval of time; to determine the equation of a curve, given different conditions (such as slope of the curve equal numerically to one-half the abscissa, or some similar problem); motion of a projectile; motion in a resisting medium; finding areas and volumes of revolution; length of a curve; areas …

The Preparation Of Glucuronic Acid From Gum Acacia, Mary Laurissa Felix

Bachelors’ Theses

Initial interest in the preparation of glucuronic acid from gum acacia was prompted by several reasons. Being interested in both the chemical and biological fields, the subject of glucuronic acid made a strong appeal. Although glucuronic acid was discovered over fifty years ago, its position in physiology remained until recently undefined. Now, however, it seems fairly certain that this compound is closely related to carbohydrate metabolism and plays an im­portant role as a detoxicating agent in the body.

The laboratory preparation of glucuronic acid is still one of the important problems of chemistry. Our present knowledge of its synthesis and …

Public Water Supplies Of New Mexico, Kenneth F. Priest

Chemistry and Chemical Biology ETDs

Distribution of population in State. The estimated population for the State of New Mexico for the year 1930 was 423,300. A close observation of the population centers shows them to be scattered over a wide range of territory. The largest city, Albuquerque, has approximately 26,000 citizens. The next sites, according to the 1930 count, are three in number, Santa Fe, Roswell, and Clovis. The remaining population including rural districts do not number over eight thousand people.

A Chemical And Biological Study Of The Waters Of Elephant Butte Reservoir As Related To Fish Culture, John Greenbank

Chemistry and Chemical Biology ETDs

The investigation of fresh-water lakes with respect to fish and other aquatic life had its beginning in Europe in the latter half of the nineteenth century. Probably the only man who may be considered to be the founder of the science of limnology was F. A. Forel, of the University of Lausanne Switzerland. Professor Forel’s work was the start of a rapidly developing branch of study, not only in Europe, but also presently in North America.

Unicursal Bicircular Quartic Studied By Inversion, William A. Uporsky

Bachelors’ Theses

The quartic equation was studied by Arab scholars after their attention to the results of their study of a cubic had not proved very significant. Abu'l-Faradsh completed the Fihrist (c, 987), and in this he refers to a problem by Abu’l-Wefa (c, 980). The Arabs were Interested in the quartic equation only as they were in the cubic, i.e., from the standpoint of the intersection of two conics.

A Study Of The Preparation Of The Combination Of Phenol-Formaldehyde Glycerol-Phthalate Resins, Mark H. Kern

Radioactive Properties Of The Subterranean Waters Of Ellis County, Kansas., Verne Lippert

Master's Theses or Doctor of Nursing Practice

Soon after the discovery of Becquerel rays in 1896, tests were made on ordinary matter to see if all matter were radioactive. Although there is evidence to show that all matter is radioactive, to a degree and under certain conditions, it has been found that the greater part of the observable effect is due to traces of radioactive material permeating all matter in general. Thus, radium and its products being the most active of radioactive substances, the surface of the earth is covered with traces of these radioactive substances but the amount varies from place to place. Moreover, determinations of …

The Control Of The Grain Size Of Tin., Robert D. Macdonald

Bachelors Theses and Reports, 1928 - 1970

The tin alloys of tellurium are extremely hard and have very great tensile strength. It was thought that the reduction of the rate of grain growth of tin with the addition of tellurium accompanied this hardening and strengthening and such way found to be true.

The Electroplating Of Cadmium From Sulfate Solutions, Lewis S. Prater

Bachelors Theses and Reports, 1928 - 1970

It has been proven that cadmium forms a very satisfactory plate on steel, which has to withstand severe corrosion, especially the corrosion of sea water and spray. The metal is now successfully plated electrolytically from cyanide solutions, but wherever work is carried on with cyanide, there is great danger of poisoning to the workers.

The Inhibitory Effects Of Carbonaceous Materials On The Cyaniding Of Gold Ores., David Currie Jr.

Bachelors Theses and Reports, 1928 - 1970

Carbon and carbonaceous material have been known to have a deleterious effect upon the cyanidation of gold and silver ores since the very beginning of the process. Organic matter is a common source of impu­rities in cyanide solution, its reducing effect being notorious.
