A Model Study Of The Induction Log Applied To The Detection Of Asymmetrically Located Orebodies, Robert Walter Piekarz
A Model Study Of The Induction Log Applied To The Detection Of Asymmetrically Located Orebodies, Robert Walter Piekarz
Masters Theses
"This research project was undertaken to determine the possibility of using an induction log of the type applied in petroleum exploration, for the detection of conductive ore- bodies asymmetrically located with respect to a borehole. Since a mathematical analysis would be extremely complex, a model study was conducted, using graphite bodies of various shapes to simulate different modes of mineral occurence.
The investigation showed that these bodies were readily detectable, and were capable of yielding anomalous curves characteristic of their geometry. The values of apparent conductivity decreased rapidly with lateral displacement, from the logging tool, as expected, due to the …

The Influence Of Bench Geometry On Blasting Effects For Vertical Cylindrical Charges, Thomas E. Pearse
The Influence Of Bench Geometry On Blasting Effects For Vertical Cylindrical Charges, Thomas E. Pearse
Masters Theses
"Blasting phenomena are affected by many factors. Previous investigators have studied many of these factors, however, the influence of charge length and explosive detonation velocity have apparently not been thoroughly examined.
It was found by this investigation that the detonation pressure of a commercial explosive is closely controlled by the detonation velocity. The detonation velocity, in turn, will largely determine the necessary blast geometry that can be successfully employed. Relationships were derived between the detonation velocity, in relation to the rock energy propagation velocity, and blast geometry for both bottom and collar primed blasts.
The resultant force magnitude and direction …

Permeability Of Poly (Ethylene Terephthalate), James G. Harvey
Permeability Of Poly (Ethylene Terephthalate), James G. Harvey
Masters Theses
"Corrosion is a phenomenon which has been the subject of extensive research, in order to find a way to control or completely stop it. Two general methods, either placing the material which corrodes in an anti-corrosive atmosphere or protecting the material which corrodes from the corrosive atmosphere, are the chief means of preventing corrosion today.
The second method is probably most widely used presently. One of the most important methods of protection is by means of organic protective coatings, or paints, but at best these only retard corrosion, due to the fact that corrosive media e.g. water vapor, ions etc. …

K₂O/Na₂O Content As A Possible Index To The Chronological Sequence Of Some Precambrian Igneous Rocks Of Missouri, Erwin Joseph Mantei
Masters Theses
"Flame photometric analyses for K₂O and Na₂O were run on 31 samples of the Precambrian igneous rocks of Missouri. Samples were collected from the field, physically prepared and dissolved by a standard method and a modified standard method of rapid silicate analyses. The K₂O, Na₂O values obtained are averages between two methods of analyses. The modified method reduces by 80% the time required to chemically digest a rock sample. The results for both methods are not significantly different. Curtin and Company Advanced Flame Photometer was used.
Results have been plotted on graphs and a chronological sequence for the named Precambrian …
A Study Of Segregation In Cast Aluminum-Uranium Alloys, B. L. Bramfitt
A Study Of Segregation In Cast Aluminum-Uranium Alloys, B. L. Bramfitt
Masters Theses
"This investigation involves a photomicrographic study of the segregation resulting from the eutectic solidification characteristics of aluminum-uranium alloys, ranging from 5 to 30 weight percent uranium. The segregation can occur in either of two manners; the first, due to the gravitational forces acting upon the growing particles which nucleate in the melt and the second, due to the mode and rate of heat transfer through the material. It was found that segregation occurred only as the result of the latter factor due to the small volume of the ingot and the rapid rate of heat transfer. The segregation was measured …

Evaluation Of Hydroxyprogesterone Acetate In The Prevention Of Canine Estrus, Kenneth B. Haas
Evaluation Of Hydroxyprogesterone Acetate In The Prevention Of Canine Estrus, Kenneth B. Haas
Masters Theses
Foreword
Thirty years ago, endocrinology was a laboratory curiosity appreciated by few veterinarians. In those rare instances when the new science escaped from the laboratory and reached the clinic, the endocrine preparations used were extremely crude and often ineffective. In the growth of endocrinology as a science, availability of pure crystalline hormones has played an essential role, and to chemical synthesis must be credited the preparations which make specific endocrine therapy possible today.
In the last two decades endocrinology has come into its own in veterinary medicine, especially in regard to sex endocrinology. But only in the last ten years …

Masters Theses
Chapter I
Definition of the Problem
Problem:
For many years there has been need for a better understanding of the dramatic arts activity in our Michigan schools. Teachers are selected, and sometimes paid, to direct school plays. In a few instances, particularly in the larger schools, these teachers attempt to develop a well-rounded dramatics program.
But what, of a concrete nature, is known about dramatic arts activity in our schools? What is being done? Where does a teacher assigned to direct a school play, or to develop a dramatics program within a single school system, stand in relation to teachers …
The First British Labor Government 1924, Donald Black
The First British Labor Government 1924, Donald Black
Masters Theses
Introduction
In 1924, the Labor Part, assumed control or Britain's political destinies for the first time. Although its tenure or office was brief, from February through October of that year, it marked an important milestone in the slow, unrelenting progress of democratic socialism in the British political spectrum after the conclusion of World War I. Not only did it reveal that Labor could assume its role as an effective opposition Party, but also that Labor had the capacity to govern in a difficult and perplexing era.

Constant X Of The Alcoholic Personality: A Research Study On The Personality Factor In Alcoholism, Jean Carpenter
Masters Theses
Chapter I
Introduction
The problem of alcoholism is one of the oldest problems in the history of mankind. Today it ranks world-wide as a major public health problem. Yet, constructive study and research on the subject did not gain much momentum until about 1935.
With the organization of Alcoholism Anonymous in 1935, the awareness of the problem spread, fanwise, throughout the fields of religion, medicine, and psychiatry. Alcohol had once presented a baffling and seemingly unanswerable enigma. But now there was a glimmering of hope in each of these separate fields that the answers might lie within its own particular …
