The Electrical Resistance Of Metals And Alloys In Their Hard And Soft States, Noah David Gerchesvky, Charles Becker Hoskins

Bachelors Theses and Reports, 1928 - 1970

It is known that the electrical resistance of annealed metals is usually smaller than that of metals in their cold worked state. The curve showing the relation between electrical resistance and annealing temperature reaches a minimum; continued annealing at higher temperature produces an increase in the electrical resistance. In the case of alloys it has been noted that a second decrease occurs at higher annealing temperature.

The following work corroborates the observance of previous investigations. The electrical resistance of cold worked copper, gold, nickel, and iron decreased with annealing and then increased, the minimum being around 300° C. or 400° …

Comparison Of Moe's Scale Of Hardness With The Rockwell, Brinell, And Scaleroscope Scales., Herbert William Hard

Bachelors Theses and Reports, 1928 - 1970

Moe's scale of hardness as used in mineralogy is admittedly rather indefinite, and no exact hardnesses are measured. The Rockwell, Brinell, and Scaleroscope machines give quite definite results which may be easily reproduced at any time.

The purpose of this investigation is to determine whether any definite relation exists between Moe's hardness and the hardness as measured by those machines commonly used for the determination of hardness of metals. If such a relation were found it would provide a more definite and accurate measure of the hardness of minerals.

Constitution And Specific Gravity Of The Ternary Mattes Cu2S-Sb2S3-Pbs, Herbert William Hard

The Effect Of Cobalt Upon Current Efficiency In The Electrolysis Of Zinc Sulphate Solutions, Joseph Newton, Louis Sanders Nuckols

Bachelors Theses and Reports, 1928 - 1970

The detrimental effect of the presence of cobalt upon the current efficiency, in the commercial production of zinc by electrolysis, has been recognized for some time. Most authorities differ upon the maximum amount of cobalt allowable. This is due to the fact that the presence of other impurities either increases or diminishes the detrimental effects of the cobalt.

The following tests were made with the object in view of ascertaining the relation, if any, between the amount of cobalt present and the current efficiency during the electrolysis of an otherwise pure zinc sulfate solution.

The results obtained from these observations …

The Importance Of Play, Laura V. Douglas

Education Student Dissertations

While reading the "Principles of Educational Sociology" by Walter Robinson Smith, the writer was deeply impressed by the statement that "Next to the family group and home life, the play group and play life exert the most vital influence upon the unfolding personality of the child." The writer wondered if it was the absence of play life, as American born children of fair social background experience it, that would in some measure explain the dullness of the Italian-American child of Sicilian and Neapolitan origin, who, as the writer knew him, was so lovable, so anxious and eager to please and …

The Development Of The Gametophyte And The Apogamous Sporophyte Of Pteris Quadriaurita, Var. Argyraea, Moore, Anno Mary Sendik

Bachelors’ Theses

In 1.848 Leszczyc-Suminski reported the appearance of sporophyte tissue element in a fern gametophyte. He observed tracheids near the apical notch of a prothallium of Pteris sulcata L. Wigand (1849) described an outgrowth from the apical notch of a fern prothallium. This was no doubt the development of an apogamous embryo. However, due to the uncertainty regarding the purity of some of his cultures, this development cannot be referred to any particular fern.

John Wyclif And His Doctrine Of The Church, Albert E. Meyer

Bachelor of Divinity

Among these precursors of Luther John Wiclif is preeminent. In point of time he is anterior to Huss of Prague, 1369-1415, of whom Luther learned many things. These two, Wiclif and Huss, no doubt are the two reformers whose influence on Luther is beyond calculation. And since Wiclif preceded even Huss, we may easily recognize the position of influence which the former occupied in relation to the Great Reformation.

Vincent’S Disease The Causes Manifestations Results & Treatment, Frederick J. Schneider

Bachelors’ Theses

Vincent’s infection is a disease of the soft tissues of the oral cavity. It was not until the last decade or two that Vincent’s disease was accorded the prominence which it merits. The incidence of this disease during the World’s War as an epidemic and the large number of cases occuring since then has brought this disease to the attention of the medical and dental profession. Today Vincent’s infection is encountered quite frequently and, in view of the fact that it is a cause of temporary and often prolonged invalidism, its causes, manifestations, results and treatment are constantly undergoing scientific …

The Unit Method Of Teaching General Science In High Schools, M. Maxentia

Bachelors’ Theses

During the past quarter of a century, while the demand for teaching science in high schools was increasing, there has been a constant experimentation going on. This experimentation was carried on, not only by the heads of the science and educational departments of our colleges and universities, the superintendents, and principals of high schools, but also by the teachers themselves. It has been a question of what to teach in general science and how to teach it so that the pupil would get the best knowledge of the subject and acquire the ability of proper application of this knowledge in …

Studies In The Magnetic Rotation Of The Plane Of Polarized Light, Charles J. Glass

Bachelors’ Theses

As an introduction to the phenomenon of magnetic rotation it is well to offer a brief explanation of the phenomenon of optical activity. According to the ’’wave theory” of light the rays from any ordinary light vibrate in every conceivable plane. If the light is reflected from a glass surface or passed through a Nicol prism it undergoes a change. If an attempt is made to pass the beam through a second Nicol prism is found that the optical axes of the two prisms must be parallel to one another or the beam will not penetrate the second one.

Asepsis In Dentistry, Harry Sher

Bachelors’ Theses

Up to the year 1860 surgery and sepsis were practically synonymous. Surgical procedures, accomplished as they were without the use of antiseptics, could not, of necessity, be done with the greatest of care, for the time element was the chief factor in success. In consequence, infections and diseases, as for example, pyemia, septicemia, erysipelas and hospital gangrene were the rule rather than the exception. Surgery was confined practically to amputations, while thoracic and abdominal operations were almost unknown.

Disease In Connection With Dentition, Lowell Meyer

Bachelors’ Theses

In order to appreciate fully the large field included in the word disease which might be included in this thesis, the word must first be defined. It is of French derivation, being coined from the two words, des or negative, plus aise or ease. Going further, Dorland’s medical dictionary further defines it as any departure from a state of health. More specifically it is a definite morbid process having a characteristic train of symptoms. It may effect the whole body and any of its parts, and its etiology, pathology, and prognosis may be known or unknown.

The History Of Gold Foil, George Edmund Williams

Bachelors’ Theses

Just when gold foil was first used is a matter of some conjecture. All historians differ in their views and it is so with the historians of dentistry. According to Dr. J. A. Taylor, it is said that Egyptian mummies exist, showing evidences of gold fillings, but at present their whereabouts are unknown. The History of Dental Surgery, Vol. 1, by Chas. R.E. Koch, cites the above incident also and further states that this gold leaf may either have fallen into the cavities or that it was placed there, similar to a gold foil filling. These statements however cannot be …

Etiology Of Malocclusion, Chester Strahorn

Bachelors’ Theses

By those who regard orthodontic treatment in the light of a purely mechanical procedure the etiology of malocclusion is given a position of secondary importance. While not belittling the necessity for thorough treatment, it has been found that some cases under the most careful treatment procedure have been failures. This leads one to suppose that in such conditions the causative factors, whether known or unknown, are still in force. Therefore it is of first importance to the orthodontist to get all possible information which bears on the cause of malocclusion. Medical literature contains much testimony to the effect that all …

X-Ray And Its Interpretation, Sol V. Stern

Bachelors’ Theses

The application of the x-ray as a means of diagnosis or pathological conditions about the teeth and jaws is a method that has achieved a position or the utmost importance in recent years. Its value has long been recognized by the surgeon in the diagnosis of grosser surgical lesions of the maxillary bones, such as fractures, tumors, impacted teeth and the like. Until recent, however, the dentist in general practice rarely found it necessary to resort to investigation by means of the x-ray. At the present time, to those who are familiar with its advantages, the constant employment of this …

Mottled Enamel, William Henry Stehly

Bachelors’ Theses

Perhaps one of the most puzzling of all dystrophies of the teeth is the macroscopical malformation called "Mottled Enamel".

This peculiarity is characterized by white, brown, and corn-colored opaque areas of enamel surrounded by apparently normal enamel. Upon examination, this enamel presents a smooth surface, though at times it may be slightly pitted. Nevertheless, the surface remains highly polished. If this surface is broken up with a bur, it is found to be of a chalky granular consistency, the whitish material at times containing the yellowish pigment which may occupy the entire thickness of the enamel. If these spots are …

Adapting Instruction To The Needs Of A First Grade, Genevieve Y. Younge

Bachelors’ Theses

Fortunately for the young child as well as for society we have evidences of the growing appreciation of the educational possibilities of early childhood. This is manifested in the opportunities provided by universities for the training of teachers of childhood. Teachers College, John Hopkins, Yale, Harvard and the universities of Iowa and Columbia offer research courses in this particular study.

In 1905 a conscious attempt was made to work out a technique of teaching built upon a new conception of the teacher as a guide rather than as a dictator, but few were interested, so the attempt was not revived …
