The Roasting And Magnetic Separation Of Wisconsin Ores And The Utilization Of The By-Products, Earl George Deutman

Professional Degree Theses

"In the Wisconsin field, the zinc blende is usually found associated with iron sulphide in the form of marcasite. This ore, after being milled and concentrated at the mines, is sent to separating plants for further treatment by roasting and magnetic separation, inasmuch as the mixed blende and marcasite concentrate, owing to the high iron content, is not suitable for the zinc smelter, and the magnetic separation scheme of separation must be resorted to"--page 1.

A Metallographic Study Of Copper Mattes, Edward James Torrence

Bachelors Theses

"The metallographic knowledge of copper mattes or mattes in general for that matter, although extensive, is, to put it mildly, rather diversified. One authority, for instance, believes that mattes are sulphide dissolving compounds there being no eutectiferous series involved. Another believes that the matte constituents enter into a eutectiferous series, compounds being present. Still a third contends that there are no compounds formed but that a simple eutectiferous range exists between certain limits outside of which the end members of the series form solid solutions with each other. In so far as there exists seeming absolute proof for all of …

The Effect Of Sulphur Dioxide Gas On Sweet Potatoes, Cotton, And Sorghum Cane Plants, Milburn Leo Dorris

Bachelors Theses

"The chief allegation made by many of the complainants sic in the vicinity of the zinc smelters is that the emanations from the stacks are detrimental to the yield of the crops, especially Sweet Potatoes and Cotton. They claim that on account of the leaves being burned or bleached, the entire plant is poisoned and weakened and the yield is thereby reduced. It was even claimed by some that the presence of the smoke in the atmosphere around the plant has a weakening effect in that it is cumulative, and, while it does not always visibly show, yet the general …

High Speed Steel - Its History, Development, Manfacture, Metallography, And Constitution, Including An Extended Bibliography, James Presley Gill

Masters Theses

"There is no doubt but that the making of Steel was known and practiced by the early Greeks probably several centuries before the birth of Christ. There have been discoveries of pre-historic forges and smelters evidently used for the making of iron and steel and it is certain that implements made of these materials dates back to antiquity. As to the methods of making the steels of antiquity there is little known, but it is quite probable since iron has a strong affinity for carbon that in the forging of the iron it's contact with the carbonaceous fuel would absorb …

The Middle Ordovician Section In East Central Missouri, Morris James Ingerson, Josiah Bridge

Masters Theses

"One of the most serious difficulties confronting anyone working on stratigraphic problems in the Ozark area is the lack of detailed faunal lists of the various formations. A great deal of general work has been done, but very few detailed faunal studies have ever been published, and correlation of the Missouri section with sections in adjoining states is often difficult.

In a recent paper, Dake has discussed the origin and correlation of the St. Peter sandstone. In this study he found considerable difficulty in correlating the various formations above the St. Peter, and at his suggestion, the present study was …

A History Of The Treatment Of Insanity In Massachusetts, Robert U. Cooper

Historical Dissertations & Theses

In this thesis, an attempt has been made to sketch the progress in the treatment of mental disorders, from the earliest records to the present time. The introductory account of the conditions before the seventeenth century briefly considers the methods employed in Europe and Northern Africa prior to that date, while the main narrative is confined principally to the advancement achieved in Massachusetts since the Colonial days. For the sake of convenience and clarity, the legislative progress, the development of institutions and the improvement in methods of treatment, have been separated, as far as expedient, in the presentation of the …

Sewage Disposal Of The City Of Milwaukee With Experimental And Construction Features, Walter W. Genrich

Bachelors’ Theses

The City of Milwaukee, for a good many years has been confronted with the big problem of sewage disposal, in asmuch as the sewage up to the present time has been allowed to flow into its rivers which in turn emptied into Lake Michigan from which the City obtained its water supply, and consequently contaminated its surrounding waters to such an extent that the City's public health was very much at stake.

Thomas W. Gilmer, Rebekah V. Lawson

Honors Theses

It often happens that the names of some men, who had a large part in shaping the past policies of our country, are not now current in the thoughts of the average student of history. It is left to biographical monographs of this nature to review the lives of these men. With this ever increasing group of names may be placed that of Thomas Walker Gilmer. He was influential in the affairs of his native state, Virginia, during the decade from 1830 to 1840. This was the period when Southern leaders really dominated national affairs and Virginia was not racking …

A History Of The Theatre In Louisville., Mary Martha Dietz

Electronic Theses and Dissertations

A child is considered by some psychologists to pass through on its way to manhood the stages through which the race has passed on its way to civilization. If this is true of a single man, might it not equally be true of a community of men? Have not most settlements, in greater or a less degree, passed through the stages of development common to the growth of all cities until they have reached the standards of their day? A company of civilized men and women going forth to make a settlement in a new place, upon their arrival at …

Courtly Love In Shakespeare's Sonnets And Plays., Rebbie Doty

Electronic Theses and Dissertations

"It is in the south of France and at a very early period that we must look for the origin of the system of Courtly Love. Gathered about several small courts, there existed, as early as the eleventh century, a brilliant society, in which woman held the supreme place, and in which, under her influence, vast importance was attached to social etiquette and decorum. Definite rules governed the sexes in all their relations, and especially in matters of love. It was to this society that the troubadours belonged, and it was love, chiefly that was the inspiration of their songs. …

George Meredith's Ideas Of Religion., Mary Ellis Duncan

Electronic Theses and Dissertations

Every man is to a greater or less degree a product of the influences surrounding his life. The more commonplace minds of the race, no doubt, are chiefly affected; and occasionally we find a man or woman of so keen an intellect, so striking an individuality, that it is difficult to trace the influence of his age upon him. Rather he becomes a power in forming the opinions of the next generation, stands in advance of his own period. Of this individualistic type if George Meredith, one of the greatest of the nineteenth century writers, if not foremost among them.

Sympathy And System In Giving., Elwood Street

Electronic Theses and Dissertations

A quarter of a century ago, Abraham Epworth Rounds, aged forty-five, came shambling out of mountainous Eastern Tennessee to one of our Kentucky cities. He was intent on making a living in easier fashion than scratching it from the lean soil of the mountainside. Among his immediate relatives were nineteen people, defective from birth – blind, deaf, feeble-minded. Abraham Epworth Rounds ran true to the family form. His vision was so defective that he had been given a few years of schooling at the Tennessee School for the Blind. In Louisville, at first, he made a precarious living for himself …

History Of The Churches Of Louisville With Special Reference To Slavery., Homer E. Wickenden

Electronic Theses and Dissertations

In the one hundred and forty years of Louisville's existence, it has grown from a log cabin settlement with no churches to a city with 269 churches and church property valued at over $30,000,000. It is impossible to measure the moral and religious force that they have exerted on the city. It can best be appreciated when one thinks of what the city would be without them. Few of us would care to live in such a city. In the field of education, Louisville churches have contributed much. Some of the first schools in the city were conducted by ministers, …

The Relation Between Man And Nature In Wordsworth's Poetry., Elizabeth Hoskins

Electronic Theses and Dissertations

While democracy was developing, while men were seeking to reform national politics and to find some means by which the people might be represented justly in the government, a new movement entered into literature to give it a broadened scope and a deepened meaning. This was the philosophical movement, at times strongly influenced by a metaphysical spirit, which often "not only prescribed the form of poetry, but furnished it with its elements". (Taine, History of English Literature, p.87). The questions, What is the meaning of life? What is man, and what is his purpose in the world? turned the thoughts …

Investigations To Determine A Possible Source Of The Carboniferous Sandstone Of The Ozark Region, John Hyer Bowles, Lewis Ely Davidson, William Ferdinand Netzeband

Bachelors Theses

"In preparing this thesis the object has been to determine, by comparisons, a possible source of the Carboniferous sandstones. It is perfectly obvious that the material came from some older formation. Considering all the possible sources from which the Carboniferous sandstone could have originated, we, have the Pre-Cambrian igneous rocks of the St. Francois Mountains, the basal Cambrian sandstone or the La Motte formation, the Roubidoux formation (chiefly sandstone), and the St. Peter formation (essentially sandstone)--Introduction, page 4.

The Heat Treatment Of Cast Steel, Fred Grotts

Professional Degree Theses

"Owing to many difficulties reported from the battle fields of France also from many sections of the United States, Mexico, Africa and South America relative to the functioning of the "Caterpillar" track an intensive research was begun early in the spring of 1919 to develop or perfect a material that could be made into intricate forms and which would have such physical properties as would withstand to a maximum degree, the abrasive action of rock and sand while at the same time having a high tensile strength and resistance to shock. A further requisite was that this material must be …

Geologic Conditions Affecting The Accumulation Of Oil And Gas In The Beggs District, Oklahoma, John Charles Miller

Professional Degree Theses

"It is generally accepted that there is lack of parallelism between surface and subsurface beds and between the productive sands in the Beggs District, a condition similar to that which obtains in the Cushing Field. The explanation of this condition as given on page 31, Bulletin 658, U.S. Geological Survey, is: 1) The difference in resistance to compression of the hard and soft beds of which the formations of the Cushing Field are composed; 2) The lenticular form of the Bartlesville sand (the equivalent of the Glen; Gas of Morris pool); 3) One or more unconformities between surface beds and …

Cooperative Marketing Of Farm Products In South Dakota, Wendell Frichiof Kumlien

Electronic Theses and Dissertations

Introduction: General Facts Underlying the Whole Problem of Distribution and Marketing of Farm Products Before entering into a detailed discussion of cooperative marketing of farm products as applied to South Dakota, I wish to briefly mention a few general historical facts which in a large part go to make up the background for the whole present day problem of distribution and marketing. 1. Pioneer America’s Agricultural Problems Mainly Those of Production During the period when our country was predominately agricultural, each farm produced practically everything it needed and was in the main self-sufficing. Each farmer produced his own wheat and …

Glucose From Corn Cobs, Barney Nudelman

Masters Theses

"The efforts of American chemists in recent years have been devoted largely to the utilization of our waste products...Corn cobs offer a particularly inviting field for research along this line on account of the large supply of cobs available and the variety of substances obtainable from them. One of the leaders in this branch of investigation is Dr. F. B. LaForge of the Chemistry Division of the Bureau of Agriculture, who has contributed numerous papers on the subject. In one of these, in collaboration with C. S. Hudson, he describes, among other things, the preparation of glucose, but recognizes the …
