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 …

Application Of Statistical Methods To Evaluation Of Mineral Deposits, Francis R. Saupé

Masters Theses

"Only in recent years have statistical methods been applied to evaluation of ore reserves. An attempt is made in this study to prepare an outline to be followed throughout the exploration in order that statistical methods can be applied to valuation problems. Particular emphasis is given to the preliminary requirements to a statistical approach. Representative parameters, sampling pattern, and sample size are discussed in separate chapters"--Abstract, page iii.

The Effect Of Heating Chill Cast Eutectics, Robert Lewis Dreshfield

Masters Theses

"This investigation is the result of the author's specific interest in two phase systems. In the past, considerable work has been done investigating the alteration of eutectoid structures; however, eutectic structures have been neglected to a great extent. Tammann did some work on the subject in 1937 as did Brown and Guy in more recent times. In both of the above cases the eutectic structure was altered by cold working and subsequent heating of the alloy.

Tammann also noted that eutectics chill cast in liquid air display a vastly different structure than those cast under equilibrium conditions and that there …

Some Properties Of Chrome-Magnesite Mixtures And Calcium Aluminate Cement-Magnesite Mixtures, Edward Charles Duderstadt

Masters Theses

"The knowledge of the physical and chemical properties of refractories is of great importance in determining their usefulness and application. The thermal expansion of refractories is of particular importance in that it affects the thermal stability of the product. A high coefficient of thermal expansion leads to greater spalling and destruction of the bricks in use. It is, therefore, desirable to develop compositions having low coefficients of thermal expansion. This investigation was undertaken (1) to determine some of the properties of chromite-magnesite refractory mixtures in an attempt to determine the optimum composition of these mixtures, the specific properties including thermal …

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 …

A Preliminary Investigation Of Natural Gas Combustion As Applied To Thermal Recovery Of Petroleum, Roger J. Schoeppel

Masters Theses

"Present application of the subsurface combustion processes in the thermal recovery of petroleum afford favorable and opportune methods of providing greater recoveries from petroleum reservoirs. This study attempts to elucidate some of the parameters controlling the complex hydrocarbon oxidation for one such process. The experimental phase consisted of investigating the combustion behavior of eight nonexplosive and one explosive natural gas-air mixtures at low and intermediate pressures. The hydrocarbon was allowed to oxidize by self-ignition under controlled conditions within environments precluding a visible flame type reaction. Progress of the reaction was followed by measuring effluent oxygen content.

Experimental evidence indicate the …

A Comparison Of The Effect Of Pvt Data Application Methods On Predicted Depletion Drive Reservoir Performance, Frederick A. Klein

Masters Theses

"It is generally agreed that the evolution of gas from oil within a reservoir is most closely approximated by the differential liberation process, while gas liberation in the flow string, surface separator, and stock tank is most nearly represented by flash liberation. To conform with this assumed physical behavior, appropriate application of both flash and differential liberation data in the computation of reservoir performance by material balance methods is indicated.

In this work, simple depletion-drive oil and gas recoveries were calculated (1) using differential liberation data only, and (2) using differential liberation data adjusted to incorporate the results of flash …

Hymnody In The Liturgical Aspects Of Worship, Philip Steen

Masters Theses

The main purpose of this study was concerned with the relationship of hymns to services in the church. The author sought to answer the question, "What are the hymns that should be used for a certain service in the Church Year?” This would have to be explained from both a theological and musical viewpoint. In order to answer this question, it was necessary to include four minor areas of study (1) the history and use or hymns and hymn tunes, {2) the history and use of the Liturgical Year, (3) the elements that determine a good hymn and (4) the …

The Apparent Effects Of Rh Hapten Ingestion On The Circulating Blood Phosphorus, Barbara Lyke

Masters Theses

The purpose of this work carried on at Western Michigan University during the past year is an attempt to elucidate further the action of Rh hapten within the body, or more specifically, the effect of its ingestion on the circulating blood phosphorus.

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 …

Iterative Solutions Of Kirkwood's Integral For Liquid Argon, Eugene D. Fabricius

Masters Theses

"A liquid or a dense gas may be regarded either as a very imperfect gas in which multiple collisions are frequent or as a distorted crystal in which the long range order has been lost. The crystal-like approach has not led to formal solutions, but it has led to several approximate treatments which can be used to give numerical results.

The two main types of approaches which have been used are: the cell theories, in which the liquid is regarded as a distorted crystal with one molecule located at or near each lattice point; and the hole theories, in which …

Effect Of Concrete Shrinkage On Stresses In Reinforcing Steel, C. Raymond Nowacki

Masters Theses

"Shrinkage is one of four phenomena that are considered as causing volume changes in concrete, the other three being creep, temperature change effects, and possible chemical disintegration. While all four are interrelated, the volume change due to loss of moisture is associated with the term shrinkage. Creep is the time-dependent change in volume resulting from external loads. A rise or fall of temperature will produce an expansion or contraction of concrete but also will affect the rate of shrinkage by increasing or decreasing the rate of moisture evaporation from the surface of the concrete.

In the design of concrete structures, …
