Cone Deformation Eutectics Using Sodium Chloride, Dolomite, And Alpite Rock, William K. Schweickhardt

Bachelors Theses

"Heterogeneous Equilibrium, alone, is an extensive study in itself and no discussion of it will be given here. It is known from this study that different phases are formed in various systems, the system consisting of two or more components. Some systems form an eutectic, which is a mixture of two solids which combine to form a liquid at a lower degree of temperature than either of the milting points of the two solids, as shown in the two component system of KCl and LiCl¹; some systems form solid solutions in which there is no eutectic formed, and the solids …

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.

Irregularities In The Productivity Of The Fry Sand In The Smith-Ellis Pool Of Northwest Brown County, Texas, Willard Ardell Schaeffer Jr.

Professional Degree Theses

"The Fry Sand of Northwest Brown County, Texas, as ordinarily defined, consists of irregularly distributed lenticular sand bodies of varying thickness, ranging up to more than thirty feet in some localities. It is quite generally conceded to be a member of the upper Strawn Group of the Pennsylvanian of Texas.

The Fry Sand is highly unconformable with relation to the strata both above and below, and is subject to abrupt changes of thickness within distances of but a few yards. It generally occurs as a light grey to white, fairly fine-grained, quite pure quartz sand, and where it is present …

Difference In Pyrometric Cone Equivalent Between Raw And Calcined Clay, Charles Alfred Freeman

Bachelors Theses

"In a recent survey of the refractories field with particular respect to the Pyrometric Cone Equivalent of different clays it was suggested that a difference in the P. C. E. value of clays might be found due to different stages of heat treatment that these clays had previously undergone. At present there is considerable apparent lack of information regarding this problem. It is evidenced largely in the samples of clay sent into commercial testing and research laboratories by manufacturers who are attempting to develop definite properties from a given clay or clay body. There is a large difference in the …

Typical Methods Of Learning, Esther Zemke

Bachelors’ Theses

In discussing methods of learning at all, it may be well to define the word method. What is meant when one speaks of method? One dictionary definition is a mode of procedure, a manner, or way as a method of teaching. Dewey defines it in this way, "Method means that arrangement of subject matter which makes it most effective for use." If this definition is used, a relationship between method and subject matter must be conceded, the one cannot be isolated from the other although the attempt is still being made in many schools of today. Some of the dangers …

The Origin Of Adventitious Roots In Coleus, Ethel Belk

Electronic Theses and Dissertations

It has long been known that adventitious roots develop from shoots and that adventitious shoots develop from roots. This fact is an important one to the horticulturist in propagating plants by stem or, root cuttings. The point of origin of these structures has not been fully presented. There have been various assumptions mad e as to where and how the adventitious structures arise. To avoid confusion, it is best to indicate that adventitious structures are those which are added to the plant; they are not the normal structures of the plant but are superfluous. They are not, however, superfluous for …

Reversal Of Polarity In Some Woody Dicotyledonous Angiosperms, Ida J. Rude

Electronic Theses and Dissertations

There has for some time existed a theory regarding organized or possibly unorganized formative substances which flow in different directions in the plant tissue and give to the supposedly polarized meristematic tissues of the plant the power to develop to maintain roots from one given or predetermined extremity and shoots from the opposite extremity only. According to theory – in case of the reversal of the position of these ends in relation to moisture, a corresponding reversal in type of plant organ produced will not ensue and persist. The experiment under discussion in this paper was carried out in an …

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

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

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.

Analysis Of New Mexico State School Laws, John Seyfried

Teacher Education, Educational Leadership & Policy ETDs

The analysis that follows does not purport to do what only a state-wide survey could properly do, that is, treat fully and minutely the New Mexico public school situation. The real intent is to occasion serious thought on the larger problems of the way for an expert state survey, preliminary to more constructive action. The extent that school problems may be treated herein is limited by the fact that only such time, effort, and other resources were at the writer’s disposal as are commonly available in the preparation of a thesis to be submitted in partial fulfillment of the requirements …

Postal Communication In The South-West, 1789-1813., Mary Angela Sweeney

Electronic Theses and Dissertations

In every civilization of which any record has been preserved, there is known to have been some organized plan for maintaining communication by couriers who were either post runners or riders mounted. The relaying of these couriers was an obvious expedient for securing greater speed. The term post is derived from positus of the verb pono. The place where the relay was effected was marked by a "post." Hence post road, post office. The colonists brought to America no ideas of postal service from England. The General Post Office of Great Britain was no t established until 1657 and the …

The Kentucky-Tennessee Boundary Line., Charles Hugh Hardesty 1894-1955

Electronic Theses and Dissertations

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 …

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 …

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 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 …

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

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.

Solubility Of Solid Paraffins In Lower Molecular Weight Hydrocarbons, Ruth Veino Goodhue

Masters Theses

"The solubility of solid paraffins in the lower molecular weight liquid hydrocarbons offers a problem of some considerable commercial importance since it is by use of these low boiling hydrocarbons that the undesirable paraffin waxes are removed from lubricating oils in the Sharples process. Little data is to be found in the literature on the solubility of the paraffin waxes, and that which is available is of a very general nature...This work was undertaken for the purpose of finding if possible, what effect this "cracking" or "telescoping" process has on the solubility of the paraffins in the liquid hydrocarbons"--Introduction, page …

A Study Of The Determination Of Silica In The Presence Of Fluorine, William Harlan Ode

Masters Theses

"The determination of silica in the presence of fluorine has always been accomplished either by difficult and complex analytical procedures or by rapid arbitrary control methods of doubtful precision...Hence, this study was undertaken in order to determine whether a more simple method might be found for the determination of silica in the presence of fluorine"--Introduction, page 1-2.

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 …
