Bonded Joint Strength Versus Loading Rate, Charless William Fowlkes

Masters Theses

"The purpose of this investigation was to determine the influence of the rate of loading variable on the apparent shear strengths of joints bonded with some of the currently available metal-to-metal adhesives. The effects of this variable are sometimes neglected by testing laboratories. The results of an experimental evaluation of the mechanical behavior of a group on modern metal-to-metal adhesives as a function of the rate of load application are used to more accurately establish the importance of rate of load considerations in adhesive joint testing. An attempt is made to explain observations of other investigators engaged in adhesive joint …

Geology Of The Copper Deposits In The Eminence Region, Shannon County, Missouri, Lanny Lee Evans

Masters Theses

"Copper has been known to occur in Shannon County, Missouri since the early 1830's. A number of small deposits in an area around Eminence has been worked intermittently up to the present day. Little detailed geologic information is available on these deposits. The geology of the Eminence region consists of Precambrian rhyolite porphyry knobs projecting through dolomites and sandstones of Upper Cambrian and Ordovician age. A conglomerate of limited horizontal extent overlying the Precambrian is found at certain localities within the region. The only structures noted are the structural highs formed where the Paleozoic sediments lap upon the knobs. The …

A Preliminary Search For Subionizers, Joseph B. Hughes

Masters Theses

"A number of physicists of recent years have been attempting to explain the basic nature of the universe in terms of particles. A few particles have been predicted theoretically, and some of these, along with many others have appeared experimentally, Searches for them have presented some interesting experimental problems and brought forth some invaluable experimental apparatus. One of these devices is the Wilson cloud chamber, with which this thesis is concerned.

Of the particles that have been discovered thus far, only the electron and the proton appear to be stable. The rest ultimately decay by the emission of photons and …

Steady State Temperature Distribution In A Rotating Disk, George Henry Morgan

Masters Theses

"The purpose of this investigation was to obtain an expression for the steady state temperature distribution of a disk of uniform thickness rotating at a constant speed in ambient air while absorbing heat through the periphery at a constant rate. Engineers encounter such problems in connection with brakes of several varieties. The general solution obtained here could be extended to similar physical problems such as grinding wheels, disk clutches, and so on.

A differential equation was obtained for the temperature in the disk by the application of Fourier's conduction law and Newton’s convection law. A solution of this equation was …

Lattice Constants, Thermal Expansion Coefficients And Perfection Of The Phase Tio, Hsiung Wei Li

Masters Theses

"TiO is one of the intermediate phases in the titanium - oxygen system with a crystal structure of the sodium chloride type. The phase extends from about 22 to 29 weight or about 46 to 55 atomic percent oxygen. A comprehensive survey of the physical properties of the phase has been made in previous investigations (see review of literature), but only impure titanium was available at that time. Therefore, some revision of the measurements had to be made. Also, neither the thermal expansion coefficients nor the temperature at which the lattice constants were measured were reported.

For precision determination of …

Stability Of Rectangular Plates By Arbitrary Deflection Method, James Arthur Jones

Masters Theses

"Many engineering structures use thin rectangular plates as members. These plates may be loaded and supported in numerous ways. The edges may be freely supported, rigidly supported, or supported by elastic members. The load may be applied normal to the plane of the plate, in which case the problem becomes essentially one of bending. If the load is applied in the plane of the plate, placing it in compression, the problem becomes one of stability.

This investigation is concerned with the stability of plates rigidly supported on all edges and having a compressive load applied to two opposite edges of …

Linear And Vortex Flow Heat Transfer Coefficients, Edward Robert Schmidt Jr.

Masters Theses

"In order to make possible better, more efficient equipment, a higher and higher rate of heat transfer has been the goal of engineers for many years. The need for heat transfer rates never thought of 25 years ago has been brought about by the advent of modern high-performance devices such as nuclear reactors and rocket motors. "A heat release of about 40,000 Btu/hr.cu.ft. is considered good practice in a modern boiler, but in a rocket or a nuclear reactor it may be 1,000,000,000 Btu/hr.cu.ft." This heat must be removed by transfer to a coolant or converted into work or the …

The Effect Of Recorded Stuttering On Listener Compression, Harold Walter William Homann

Masters Theses

Chapter I.

The Problem

Justification of this research. This experiment was designed to test the prevalent opinion that poor speaking reduces comprehension. Typical of such opinions is the conclusion of Knower, Phillips, and Koeppel¹, who state:

"The comparative effectiveness of speaking and oral reading as methods of presenting material depends upon the quality of performance. Poor speaking seems to be the least effective method of presenting informative materials. There is a direct relationship between the quality of speaking performance and the amount of material recalled. Poor speakers produced least recall."

Of the many factors which contribute to effective …

The Effects Of Manifest Anxiety On Stuttering Adaptation, Joseph Agnello

Masters Theses

I. Introduction

When stuttering behavior is viewed as a problem in learning, the phenomenon of adaptation frequently receives attention. A standard adaptation experiment consists of having the person who stutters re-read the same passage, or a passage of equal difficulty, a specified number of times. Under these conditions a relative reduction¹ in stuttering frequency usually occurs. Experimentalists and clinicians alike have long been puzzled as to why this decrement takes place, since stuttering is generally considered by many writers^2,3 as a self-reinforcing disorder; that is, stuttering produces more stuttering.

The present experiment was designed to investigate the effects, …

A Survey Of Management Opinions Of Noise In The Pulp And Paper Industry, Carola Trittin

Masters Theses

Introduction

The pulp and paper industry is the fifth largest in the United States, dollar-wise, and is also the third fastest growing industry in the United States (1). There are between 375,000 and 400,000 people employed directly in the pulp and paper mills in the United States and Canada. A nation-wide survey on the importance of noise in this industry is needed to help clarify the effects, if any, that noise has upon its employees.

By definition, noise is non-harmonious sound. When the subject of noise is mentioned, many suggestions are given on places where such a study should be …

The Analysis And Evaluation Of Supervisory And Managerial Personnel, Robert A. Huston

Masters Theses

Introduction

The rapid growth of American industry during the first half of the Twentieth Century has brought managements face to face with the necessity to delegate responsibility and commensurate authority to the various echelons of the supervisory and managerial personnel. The owner-manager era is a thing of the past. Gone with it is the intimate relationship that once existed between the owner of the business and those who worked for him. In its place has arisen the corporation, a statutory entity that cloaked ownership with impersonality.

Coincidental with the change of character of ownership and, indeed, one of the major …

Investigation Of The Geometric Effects Connected With The U-Effect-Iii, Anthony Edward Hoffman

Masters Theses

"Statement of Problem: The investigation reported herein is of the dependence of the voltage output due to the U-Effect-III upon the geometry of the tube. The geometry of the tube is defined to include the inner diameter of the tube as well as the size and number of the mercury and electrolyte drops. The previous experimental study of the effect did not include an investigation of the effects of the geometry of the tube, as defined above, on the voltage output. It seems that information as to the dependence of the output voltage on the geometry of the tube would …

Methods To Improve The Metallurgy Of Bolivian Tin Ores, Oscar Davila-Michel

Masters Theses

"Tin is a rare element; among the base metals it is one of the rarest. Although it was one of the first metals used by man and has been used since prehistoric time, the ore-dressing and metallurgical methods of tin are inefficient and very wasteful.

The only tin deposits of importance in the Americas are located in Bolivia, South America, and it is in Bolivia that the problems of tin metallurgy are greatest. More than 50% of the tin that is mined in Bolivia is lost in the tailing dumps of the beneficiation plants. In a country where the export …

Performance Characteristics Of A Tubular Regenerative Heat Exchanger, Harry J. Sauer Jr.

Masters Theses

"The term regenerator is widely used to define any type of heat exchanger in which the heat is alternately stored and removed...The present investigation is concerned with the calculation of the characteristics of the "single-blow", tubular regenerative heater, its dimensions and performance. In the analysis in this thesis, the heat is considered to be stored in bundles of tubes initially preheated by hot gases flowing through the heater and subsequently cooled by the flow of air. This paper makes no attempt to deal with the effects of radiation from the outer row of tubes to the heater shell"--Introduction, page 1-3.

Rheological Measurement Of A Starch Suspension As A Dilatant Fluid, Earl Edward Pape

Masters Theses

"The measurement of the rheological properties, consistency of viscosity and fluid type, necessary for system design calculations, has fallen behind the industrial applications for non-Newtonian fluids. In the petroleum industry in particular, the process of well flow stimulation known as Hydraulic Fracturing utilizes the properties of various non-Newtonian fluids to carry sand at high flow rates to the formation to be fractured. Other non-Newtonian fluids in the petroleum industry are Bentonite clay drilling fluids, whose unique gelling properties are helpful in suspending drill cuttings when the circulation of the fluid has ceased. In Newtonian liquids and gases the consistency is …

Performance Parameters Of Low-Density Ammonium Nitrate Base Explosives; Experimental Results And J. Taylor's Method, Mohammad Azhari Warga-Dalem

Masters Theses

"Ammonium nitrate has been known to the explosive industry for a long time. Compelled by the ever increasing mining costs, in 1954 "Akremite" was introduced to the market. It is a simple carbonaceous ammonium nitrate mixture and is the cheapest explosive available to the open-pit operators.

During the following years considerable amount of research was done, resulting among others with the introduction of ammonium nitrate-hydrocarbon mixtures as an explosive. During the Second World War research was done toward the refinement of the hydrodynamic theory. Several methods of calculating the detonation velocities of the explosives were introduced: Brown (1942), Kistiakowski and …

An Application Of Cathodic Sputtering To The Etching Of Metallographic Specimens, Robert Ruch

Masters Theses

"The U. S. Bureau of Mines at Rolla, Missouri has for some years been conducting research on manganese-copper alloys. The study of the physical metallurgy of these alloys -- dissimilar metal couples -- has always been complicated by the difficulty of satisfactorily etching this material. It was felt that by introducing a new etching technique, cathodic bombardment, satisfactory etching might be accomplished. On this basis the following research program was proposed:

1) To survey the present state of art of cathodic etching, etching by means of cathodic sputtering;

2) To design and construct suitable equipment for the experimental study of …

A Study Of Cholesterol And Lecithin Blood Levels In Rh Sensitized Women Treated With Rh Hapten, Franklyn Lewis

Masters Theses

The Problem And Its Background

Introduction

Perhaps one of the most popular subjects, and a subject which has been discussed a great deal by the layman is that of Rh and Rh incompatibilities.

Landsteiner¹ discovered the Rh property of human blood by means of immune sera prepared with the blood of rhesus monkeys. He was assisted in this work by Wiener², who states that the Rh property was found to be present in about 85% of white individuals, and independent of the blood groups and M-N type. It is these individuals who are referred to as Rh …
