A Sociometric Study Of Popularity And Academic Achievement In A Ninth Grade Class, Elizabeth V. Banks

Masters Theses

The Problem and Its Background

Introduction

It is common knowledge that education consists of more than training for academic achievement. It consists of teaching whole individuals how to live effectively in their social environments. Although it is almost impossible to teach them all the skills directly they can be helped to learn through experience a great number of them for themselves. These view-points with respect to the teaching of students are held not only by a great number of educational authorities but are also part of the educational practice of a great number of teachers.

Effect Of Viscosity On The Cetane Number Of A Diesel Fuel, Moris Bolay

Masters Theses

"The object of this paper is to determine or rather experimentally establish the effect of a change in viscosity of a given diesel oil in regard to the ignition quality (cetane rating) of the oil.

The author did not attempt to prove why or find out how much the cetane number was affected. But, merely, tried to experimentally verify the fact that the cetane number of the fuel used underwent a change when its viscosity was decreased by preheating it.

Since his professional interests lie in the field of automotive engineering, several thesis problems were suggested to him by Dr. …

Plastic Deformation Of Rocks, Muhammed Abdul Waheb

Masters Theses

"The purpose of this investigation is to search for a method by which the strength properties of a rock may be described.

For this purpose, an attempt has been made to find out some relationship by which the rooks may be classified or described. For the solution of problems of mine stability, the mechanical properties of a rock should be known, i.e., hardness, toughness and strength. It is difficult to make a study of some method of classification or description of a rock without knowledge of these properties.

With a view to achieve the solution of a general classification for …

A.C. Circuit Interruption, Palmer L. Anthony Jr.

Masters Theses

"In the last few years the transmission voltages have increased tremendously. Along with the voltage increase came increased load carrying ability for the circuits. The first few links of a new 330 KV transmission system are now under construction in this country. Sweden is already operating a 380 KV line. It is expected to carry a load as high as 850,000 KW on a single circuit.

Interconnection between systems in adjoining areas is a practice to get further operating benefits. The benefits are - reduction of necessary reserve capacity, increased load diversity, and decreasing losses.

Both of these developments bring …

Masters Theses

"Purpose of Investigation: This study was undertaken to describe and analyze the system of haulage as practiced in mines of the Tri-State District by the Eagle Picher Mining and Smelting Company.

The investigation is concerned with all of the operations involved in moving the broken rock and is composed of three distinct procedures: loading, hauling, and hoisting.

One of the important items in the cost of mining is the movement of ore and waste to the surface for further disposition. Increased efficiency of transportation should introduce lowered production costs.

In this paper the efficiency of the present equipment and the …

X-Ray Studies Of Zirconium Cyanonitride, John T. Ballass

Masters Theses

"The purpose of this research was to study, by means of x-ray and metallographic analysis, a material reported to be zirconium cyanonitride.

The x-ray analysis had a three fold purpose, the determination of the symmetry of the constituents, the number of phases present, and the crystal structure type. Metallography was used to confirm some of the results obtained by x-ray analysis establishing certain definite phase relationships present in the microstructure.

The sample investigated contained three principal elements namely zirconium, nitrogen, and carbon. On the basis of constitution this work is a contribution toward the development of the three component equilibrum …

Clipper Amplitude Modulator, Durmuş Öcal

Masters Theses

"An amplitude modulated wave is defined as a wave form in which the amplitude of a sinusoidal signal (carrier) is varied in accordance with a modulating signal whose frequency is much lower than the frequency of the carrier signal. Numerous devices have been found for generating an amplitude modulated wave. In some modulators the amplitude of the carrier is actually varied in accordance with the modulating signal. In other types of modulators the carrier and the modulating signal are simultaneously applied to a nonlinear element or circuit. The output of this non-linear element is a distorted wave containing many frequencies. …

The Application And Utilization Of Mining Models For Instruction And Display, William M. Shepard

Masters Theses

"The subject of the utilization of mine models for instruction and display at institutions offering courses in mining engineering has not been widely discussed in the literature. The value of models as visual aids in teaching has long been recognized, and they have been extensively employed by some institutions and by some instructors. However, the writer believes that a wider range of types of models are suitable for instruction purposes than have been employed in the past, and that mining models, properly arranged and adequately labelled, may be used in displays to give both the layman and the beginning student …

An Experimental Study Of The Effect Upon The Current Distribution And Radiation Pattern Of Crossbars On Yagi Receiving Antennas, Gerald F. Sinnamon

Masters Theses

"The development and widespread use of radar systems in World War 11, and the post-war television boom, has brought about a large amount of investigation in antenna arrays. One of the types of antennas commonly used on radar systems during the early part of the war, and one which finds wide usage today as a television receiving antenna, is the well known Yagi antenna...

Since television antennas are usually mounted out of doors, the antenna must be made mechanically strong to prevent whipping or twisting due to wind, and to prevent sagging due to icing or to its own weight. …

A Study Of The Effect Of Jointing On The Blasting Of Granite, Graniteville, Missouri, Avery Ala Drake

Masters Theses

"Purpose of investigation: The purpose of this investigation is to attempt to determine the influence that joints exert upon the blasting of granite and if joints are induced by blasting. The problem grew out of an explosive evaluation project that was conducted by the Mining Department, Missouri School of Mines. In late May 1950, the project was moved into the granite area near Graniteville, Missouri. It became apparent upon study of this area that the jointing would have certain effects upon the results obtained. Dr. J. D. Forrester, Chairman, Department of Mining Engineering, Missouri School of Mines, Rolla, Missouri, suggested …

An Investigation Of Ruthenium As A Possible Ceramic Colorant, John Charles Williams

Masters Theses

"Some portion of almost every writing dealing with the historical development of ceramic products is devoted to describing the application of colors as found on even the most ancient specimens known to exist. A vase bearing the name of an Egyptian king living 5000 B. C. was glazed in green and inlaid with purple. There are many such examples of the utilization of color in ceramics which illustrate to a certain extent the aesthetic tastes of the very earliest and primitive civilizations.

In those early times, only a few elements were known and available that could be used for such …

A Study Of Some Raw Materials For The Manufacture Of Silica Brick, Charles E. Shulze

Masters Theses

"The ability of silica to carry a load to within a few degrees of its melting point and its tolerance for comparatively high concentrations of iron oxide and lime, have enabled it to maintain its position as the number one steelplant refractory. It is estimated that at least half of the volume of refractories used in the steel plant are silica bricks. Consequently the manufacture of silica refractories forms an industry of considerable importance.

Raw materials suitable for the manufacture of silica brick are widely distributed, but only a small number of deposits are used commercially for one reason or …

Mineral Composition In Relation To Particle Size For A Missouri Plastic Fire Clay, John Edward May

Masters Theses

"From the rather modest beginning of the refractory industry in Missouri prior to the Civil War, the industry has grown to challenge those of other states as the third largest producer of refractory clays and products in the United States. As Roberts (1950) points out, the development of the metallurgical and glass industries increased the demand for high grade refractory materials. A prominent factor in the development of the fire clays of Missouri was the discovery that flint clay could be mixed with the plastic or semi-plastic refractory clays to yield an excellent product. Perhaps the most important reason many …

Series Capacitors, Emcet Bilgeer

Masters Theses

"Static capacitors as an element of transmission and distribution circuits first appeared in the form of shunt capacitors. These shunt capacitors were primarily used in power factor correction. They can be regarded as a load in the circuit which draws a loading current. This loading current fleeing through the reactive line produces a voltage rise, thus reducing the voltage drop between sending and receiving ends. This phenomenon helps the voltage control of the feeder as well as power factor correction. The disadvantage of the shunt capacitor is its inflexibility. The shunt capacitor is connected across the line; hence the voltage …

Square Wave Modulation, Richard Henry Duncan

Masters Theses

"Modulation of a radio frequency carrier can be defined as the variation of some wave parameter such as amplitude, frequency, or phase, in accordance with intelligence to be transmitted. An unmodulated carrier is simply a continuous sine wave and contains no information other than the fact that the transmitter has been turned on. The spectrum of an unmodulated signal consists of a single frequency. Any type of modulation is characterized by the appearance of additional frequencies, known as sidebands. One of the fundamental problems in radio engineering is to reduce the number of sidebands to a minimum and still adequately …

A Study Of Volatility And Desulfurization Of Titanium Disulfide, Sheng-Tai Shih

Masters Theses

"The application of high vacuum for the promotion of metallurgical reactions is a comparatively new development. During the war the need for high vacuum in producing magnesium by the Pidgeon Process and in certain phases of uranium purification led to the perfection of both equipment and technique for high vacuum operations. These developments helped open the way for the entirely new field of vacuum metallurgy.

The reduction of metal oxides in vacuum has been studied by Dr. Kroll and Dr. Schlechten. They have been able to reduce many metals from their oxides under reduced pressures using carbon as a reducing …

A Study Of Radio Frequency Converters And Mixers, James J. Skiles

Masters Theses

"This thesis will present a detailed discussion of the principles of frequency conversion and the problems attendant to the design of converter stages. The topic of harmonic conversion has been singled out for a more extended treatment than is now available in the literature. This topic is the subject of the experimental investigation portion of this thesis. Harmonic conversion has applications in U-H-F receivers as well as in "Double Superheterodyne Receivers".

The discussion given to the frequency converter in the first section of this thesis will be without regard to any applications. General theory will be stressed, and most of …

The Effect Of Inlet Air Temperature On The Efficiency Of A Spark Ignition Engine, John B. Toomey Jr.

Masters Theses

"The object of this thesis is to determine the effect of inlet air temperature on the efficiency of an internal combustion engine. In most text books the subject is dismissed with mentioning the negative effect of warm air on the maximum output of the engine. This fact is recognized but since most engines are run at maximum output only a small percentage of the time, it would be possible to control the air temperature as the situation demanded. With the assumption that cold air could be used when full power is desired, it was decided to determine the effect of …

Airflow Through Metallic Screening, Norman Bernard Wolk

Masters Theses

"The selection of the problem for which this paper offers a solution was made from a list of thesis subjects submitted to Dr. Aaron J. Miles by the United States Air Forces. This suggestion called for the development of a method whereby air flow through woven materials such as metallic screening and woven cloth could be predicted in terms of the pressure drop across the material. The range of the pressure differentials to be investigated was from zero to twenty inches of water.

After some preliminary work it became obvious that an investigation of the air flow through all types …

A Method Of Mining The Kumtepe Lignite Deposit Of Turkey, Hilmi Dokuzoglu
