A Study Of Petroleum Emulsions, Howard Halcomb Gross
A Study Of Petroleum Emulsions, Howard Halcomb Gross
Masters Theses
"The producer of crude oil experiences a continuous source of trouble and loss in the emulsion problem. These emulsions cannot be entirely discarded for several reasons: First because it is a waste of natural resource and second because there are such large quantities that no feasible outlet could be found on account of fire hazard and stream polution [sic]. Further to keep these emulsions in storage for slow settling puts a storage burden on the producers. To handle the emulsions most economically many producers are treating them and a large number of methods for treating have been devised. The object …
Heavy Minerals In The Roubidoux And Other Sandstones Of The Ozark Region (Mo.), Cletus Daniel Cordry
Heavy Minerals In The Roubidoux And Other Sandstones Of The Ozark Region (Mo.), Cletus Daniel Cordry
Masters Theses
"In this study an attempt has been made to determine the usefulness of heavy minerals for correlation of formations over a limited area, in the heart of the Ozark uplift in southeast Missouri. The Roubidoux formation, already definitely correlated by other means, has been rather systematically sampled throughout the area, and the heavy minerals determined to ascertain their dependability for correlation purposes. Several samples from other horizons have been studied for comparison with the Roubidoux. Also, within the area studied there are numerous isolated patches of sandstone, the horizons of which have not been definitely determined. Samples from a few …
A Means Of Making A Segregate Preparatory To Chemical Analysis Of The Sulphide Minerals In A Low-Grade Dolomitic Ore-Pulp Containing Lead, Zinc, And Copper, Julius Bruce Clemmer
A Means Of Making A Segregate Preparatory To Chemical Analysis Of The Sulphide Minerals In A Low-Grade Dolomitic Ore-Pulp Containing Lead, Zinc, And Copper, Julius Bruce Clemmer
Masters Theses
"The object of this investigation was to find a means of obtaining from a low-grade dolomitic ore pulp a segregate of the sulphide minerals of lead, zinc, and copper preliminary to chemical analysis so that the chemist's error of 0.03 per cent would be divided by the ratio of the segregate to the entire pulp, and hence be reduced. Two methods of obtaining the segregate were investigated: (1) By float-and-sink tests, and (2) by selective dissolution of the dolomite, which is the main gangue constituent of the ore"--Object of Investigation, page 3.
The Preparation Of Certain Inorganic And Organic Compounds Which May Be Of Use In Mineralogical Separations, Clarence Jay Black
The Preparation Of Certain Inorganic And Organic Compounds Which May Be Of Use In Mineralogical Separations, Clarence Jay Black
Masters Theses
"In the work with minerals, there has been many mechanical means devised whereby the ores could be separated from the gangue and other material. Among those means which are used to-day, especially in the laboratory tests upon minerals, to quickly determine the value of an ore, heavy liquids have become quite popular. This means of mechanical separation is merely to place finely ground ore containing particles of varying density into a liquid of heavier density than the greater portion of the mineral, which will allow the heavier portions to sink and the lighter to float, which is usually gangue. This …
The Solubility Of Inorganic Salts In Carbon Disulfide: The Case Of Aluminum Bromide, Herman Henry Kaveler
The Solubility Of Inorganic Salts In Carbon Disulfide: The Case Of Aluminum Bromide, Herman Henry Kaveler
Masters Theses
"Since about 1890, the interest in solubility has turned to a large extent to the investigation of the solubility of compounds in organic solvents. This has resulted in a great deal of work being done on the solubility of inorganic salts in non-aqueous solvents. As this mass of data steadily accumulated, the theoretical considerations of solubility and the ideal solution made rapid advances, as Hildebrand has pointed out. We express as much wonder over these theoretical advances as chemists did over the discover "that salts do dissolve in organic compounds". To add some useful data to that already accumulated on …

The Use Of The Chemico-Pathology Laboratory In The Dental Clinic, Matilda Mary Steinbrecher
The Use Of The Chemico-Pathology Laboratory In The Dental Clinic, Matilda Mary Steinbrecher
Bachelors’ Theses
The reason why the practice of dentistry is sometimes criticized to-day is because it was separated from the practice of medicine at a time when mouth disorder as a cause of systemic disease was not recognized, and mechanical restoration of teeth was made the foundation of dentistry. The keynote in judging a man's ability was by the expertness of his mechanical skill. This attitude toward dentistry, not only by the medical men but by the laity as well, has been a regrettable weakness in the dental profession. The dentist's work was regarded as entirely mechanical and for the purpose of …
The Athenian Democracy Its Influence And Effects On Modern Democracies, Messiah Ketchichian
The Athenian Democracy Its Influence And Effects On Modern Democracies, Messiah Ketchichian
Bachelors’ Theses
In this thesis, I hope to treat the origin and. the functions of Athenian democracy, and attempt to interpret its influence and effects on modern democracies. Furthermore, I wish to convey the idea, and bring out the facts from my investigation of ancient democracy of Athens, that the modern democracy both in England and in the United States is not wholly the mental product or the political ideals of Anglo- Saxon race as the English speaking peoples on both sides of the Atlantic seem to think or boast about just governments in England, in self governing dominions, and in America. …
Ford Madox Ford: A Conscious Artist, J. Wallace Carroll
Ford Madox Ford: A Conscious Artist, J. Wallace Carroll
Bachelors’ Theses
He had often said that he would never write a worthwhile novel until he was forty, and that prediction proved quite true. Perhaps he had correctly estimated his own ability, or perhaps he had failed to put forth his best efforts merely to keep faith with his judgment. Such a course of action would be entirely consistent with the character of the conscious artist who is Ford Madox Ford.

This dissertation is arranged in three parts. First is a bibliography of the material used in the study with a roster of the officials of each state that may have jurisdiction over any thing pertaining to the boundary line. Second is an account of the various efforts made by each of the states concerned to establish and confirm the line. Chapter one relates the efforts of the English Government to establish the line between Virginia and North Carolina. Chapter two is an account of the two states to establish the line, from the time they declared themselves free of English …
Experimental And Observational Geometry, Albert D. Field
Experimental And Observational Geometry, Albert D. Field
University of the Pacific Theses and Dissertations
Geometry has the distinction of being one of the oldest subjects given in the high-school.
Its subject-matter was formulated and organized by the Greeks into a fine system of thought before the time of Christ. Since leaving the hands of the Greeks, geometry has received only a few minor changes, and these largely in recent years.
Heretofore, the study of geometry has been made almost entirely dependent upon memory and reasoning. Geometricians have been slow in adopting the laboratory and observational methods.
This thesis has been written to encourage the student in his work of observing geometrical forms, and in …
Drainage And Irrigation Of A Thirty-Six Square Mile Tract Of Land In Louisiana, Ralph Charles Dodge
Drainage And Irrigation Of A Thirty-Six Square Mile Tract Of Land In Louisiana, Ralph Charles Dodge
Bachelors Theses
"Because of the fact that I was unable to secure all of the necessary data concerning the topography of the section in question I made several assumptions. However, these assumptions were not made at random, as the land lies on the coast and is subject to the same conditions as does the southern portion of Jefferson County, Texas, of which I have accurate knowledge and which lies directly across Sabine Pass"--Introduction, page iv.
The Solubility Of Inorganic Salts In Ether, Clarence Bernard Weiss
The Solubility Of Inorganic Salts In Ether, Clarence Bernard Weiss
Masters Theses
"The data on the solubility of inorganic salts in ether is scarce. Eder made a study of this subject and found few salts whose solubility could be called high. He used both hydrated and dehydrated salts. Neumann mentions the great solubility of aluminum chloride in ether, but did no work to find its exact proportions. It was thought that perhaps with this particular salt, a solubility curve might be obtained that would be both instructive and interesting. Therefore the major portion of this work was spent in determining the solubility of aluminum chloride in ether. Other salts whose solubilities were …

Modern Youth And Literature (With Emphasis Upon Creative Education), Ralph Westerman
Modern Youth And Literature (With Emphasis Upon Creative Education), Ralph Westerman
University of the Pacific Theses and Dissertations
In writing a thesis dealing with such an amazingly wide subject as modern youth one is staggered by the quantities of material that one must read. It is true that most of the research work concerning the young American is propaganda of one kind of another: someone must prove that youth is degenerate; or someone must prove that youth is god-like. Between these two extremes much has been written in an attempt to prove that youth is simply youth--little or no different from the youth of any other age. It is all very illuminating and it is all a bit …
The Tacna-Arica Dispute, Edith Eileen Knoles
The Tacna-Arica Dispute, Edith Eileen Knoles
University of the Pacific Theses and Dissertations
The history of the Tacna-Arica Dispute presents varied problems to the student of international relations. From the period of Spanish American independence to the present there have developed new aspects of international law and practice according to the light brought upon it by several generations of experience, The circumstances of Per’s throwing her influence with Bolivia in the War of the Pacific in order to preserve the “balance of power” illustrate the traditional type of alliance entered into by nations fearing the growing strength of neighboring countries; the appeal to patriotic impulse and sentiment in carrying on a war whose …
A History Of Education In Porto Rico, Elna Mae Miller
A History Of Education In Porto Rico, Elna Mae Miller
University of the Pacific Theses and Dissertations
The purpose of this thesis is to give an outline of education and its progress on the island of Porto Rico, from the coming of the Spaniards through the years of American control. It is not written for experts on Porto Rican education, although it is the data of such experts, that has made this work possible. It is rather for those American students, who know little or not.hing of this possession, its early history, or its educational problems past or present; and yet who, like myself hear more and more of this island each year, so fast is it …
The Social And Economic Basis For Child Welfare Standards, Margaret Anderson
The Social And Economic Basis For Child Welfare Standards, Margaret Anderson
University of the Pacific Theses and Dissertations
It has been said that children are the nation's most valuable asset, since the future of the nation depends on their inborn possibilities and Share and the development of these possibilities. From an economic standpoint, the bringing up of a child is an investment, in fact, a very profitable investment, not so much for the immediate family as for the community as a whole.
Hellenism And Christianity, Philip Albrecht
Hellenism And Christianity, Philip Albrecht
Master of Sacred Theology Thesis
The purpose of this thesis is to show the relation of Hellenism to Christianity. It will deal especially with the action and influence of the one upon the other in the Apostolic Age. It would he hardly possible that two such great movements as Hellenism and Christianity could exist at the same time without affecting one another.

A Few Notes From The Sanitary Engineering Field, Ronald Davies Ward
A Few Notes From The Sanitary Engineering Field, Ronald Davies Ward
Professional Degree Theses
"This paper, it is felt, may appear to be a somewhat disconnected discussion of a few points that have come to the writer's attention from his limited experience and practice in the field of Sanitary Engineering. It has not been the intention, however, to provide a discussion of continuity which would take the reader from the ground up through the process involved in the design and construction of any particular structure, system, or plant; but rather is it to be considered the writer's attempt - although probably a somewhat feeble one - to set forth in a note-book, as it …
Biological And Psychological Study Of Twenty Pairs Of Twins Ranging From Seven To Eighteen Years Of Age, Albert C. Worden
Biological And Psychological Study Of Twenty Pairs Of Twins Ranging From Seven To Eighteen Years Of Age, Albert C. Worden
University of the Pacific Theses and Dissertations
Although twins have always been of great Interest the only early data available are upon conjoined twins. The first record of such twins, which 18 known, 1s of the Bid-dendent Maids in the year 1100 A. D. From that date to the year 1824 when the Siamese Twins were born and later made famous by Barnum and Bailey's Circus, there have been many Interesting accounts of conjoined twins, but the nature of the present work and the probable unreliability of these accounts would make any discussion on the subject of these early conjoined twins not worth while.
An Investigation Of The Mechanics Of Oil Migration From The Source Beds To The Reservoir Beds, William Reed Quilliam
An Investigation Of The Mechanics Of Oil Migration From The Source Beds To The Reservoir Beds, William Reed Quilliam
Professional Degree Theses
"The study of the migration and accumulation of petroleum has very naturally been analytic, with the result that we have had a variety of studies of its several features. the generation of petroleum, its migration and its accumulation in reservoir rocks is not a rapid process which may be accomplished and terminated in a comparatively short time, but one of long and almost continuous operation from the time of its inception. In this study the author is not attempting to formulate a new theory for the movement of oil from its point of origin to its final point of accumulation …
Diversion Of Mississippi Flood Water As Aid To Flood Control, R. W. Campbell
Diversion Of Mississippi Flood Water As Aid To Flood Control, R. W. Campbell
Professional Degree Theses
"For many years the lower Mississippi River valley has been in constant danger from high water causing disastrous floods. The important city of New Orleans, our typical French city, is below the surface of the Mississippi River at all stages, and its only means of protection at present is by a levee. Should this bulkwark give way, the whole of that city would be submerged. With this danger in mind, the writer has undertaken a study for, and design of a spillway above the city to reduce the danger caused by high water. Each year flood heights increase and the …
