Performance Of A Reciprocating Packed Extraction Column, Thomas Vardaman Konkle

Masters Theses

"The performance of a mechanically-aided liquid extraction column was investigated utilizing the methyl isobutyl ketone-acetic acid-water ternary extraction system. Mechanical power was added to the extraction system by reciprocating a wire-mesh packing of high void volume at various frequencies and displacements. The effects of total throughput on performance were studied in increments of 5,000 pounds per hour per square foot up to the onset of flooding, and the column performance was evaluated as a function of power addition to the extraction system. In comparing the various types of mechanically-aided extraction columns, it was determined that the throughputs achieved with the …

Near Optimal Sequencing :N Jobs And M Machines; All Jobs To Be Processed Through The Same Order Of Machines, Larry Glen Clark

Masters Theses

"There is a need, in industry, for an efficient method of determining an optimal sequence for processing a number of jobs through two or more machines. A method which requires a minimum amount of time would be most beneficial. The purpose of this study has been to define such a method. Tests on the method described indicate that although an optimal solution is not always obtained, the solutions obtained are quite good and due to the time factor the method would be beneficial to industry"--Abstract, page ii.

A Study Of The Influence Of Shock Waves On The Stability Of Rock-Bolt Anchorage, Helmut W. Habenicht

Masters Theses

"An experimental method was developed to compare strain data for rock and rock bolts when exposed to shock waves released by blasting. During a 32-day period of experimentation, one rock sensor and four rock-bolt sensors were observed simultaneously. By their placement in the side wall of a structurally stable drift, secondary static stresses were excluded. Bolt gage responses, then, could be considered to originate only from a decay of anchorage stability during static conditions or as a reaction to the vibrations. Interpretation of test results indicated a distinct loss in bolt-strain during vibrations, accompanied by a smaller but steady loss …

A Study Of Certain Effects Of Local And Topical Anesthetics On The Speech Of Stutterers, Charles Michael Gross

Masters Theses

Chapter I

Introduction

Introductory Statement

The ability to monitor one's own vocal output is essential if one is to produce and maintain normal speech. Speech would become progressively defective if one were unable to detect errors in voice, articulation, or rate. The preservation and maintenance of speech require the coordination of several automatic systems in the human body. One of these systems includes the tactual-kinesthetic purpose of defining the tactual-kinesthetic role and its relation to feedback cues in the production of speech.

Since speech is controlled by more than one automatic feedback system, it is essential that an investigation of …

Southern Expansion In The Caribbean Region, 1850-1860, Keith Ross Speiran

Masters Theses

The Background: 1846-1850

The term "Fillibuster" has a different connotation in modern times than that of a hundred years ago. Today according to The American College Dictionary, the term means, "a member of a minority in a legislative assembly who resorts to irregular or obstructive tactics to prevent the adoption of a measure generally favored, or to force a decision almost unanimously disliked." The dictionary also gives the older definition, which will be used in this paper. This meaning is "an irregular military adventurer; a freebooter or buccaneer."

The purpose of this thesis is to describe a number of …

Ailred Of Riveaulx The Consistency Of His Life And Writings With His Thought And His Profession As Cistercian Monk, Tyrrell Hughes

Masters Theses

First paragraph:

The author confesses to a profound emotional involvement with AiIred of Rievaulx, Saint of the Church and man whose love was charity, the love that is like God's love. But this zealousness on his behalf was born after analysis of and reflection on Ailred's life and writings, comparing these judgments with the treatments he has received at the hands of various scholars, among them the fine names of David Knowles, F.M. Powicke, C. H. Talbot and Aelred Squire. The initial reaction induced by the comparison was indignation at the injustice done AiIred, but much more at the seeming …

Comparative Myology Of The Pectoral Girdle Of Microtus Pennsylvanicus And Pedomys Ochrogaster, Marie Hagerman

Masters Theses

Introduction

The meadow vole Microtus pennsylvanicus (Ord) and the prairie vole, Pedomys ochrogaster (Wagner) are two species of grassland-dwelling, slightly fossorial rodents which are very similar in appearance and general body size and proportions. The objective of this study was to prepare a detailed description of the muscles of the pectoral girdle of M. pennsylvanicus and to compare them to P. ochrogaster. It was hoped that the study might indicate similarities and dissimilarities in the ways in which the two species have adapted to their mode of life and show whether or not they share common adaptations of the pectoral …

Analysis Of The Relationship Of Items On An Employment Application To Length Of Service, Margery Hidenach White

Masters Theses

Certain factors on an application blank may be predictive of length of service and of job success. If personal history items which successfully differentiate between the short-term and long-term employee or the desirable and undesirable employee can be identified, it would assist in the selection process.

A review of recent research concerning factors on an employment application as related to job success reveals that, although considerable research was done in this area during the early 19SO's, there has not been much published in the past two years. Apparently there are three reasons for this: (1) early results indicated high validity …

An Investigation Into The Possible Relationship Between Phonic Ability And Articulatory Defectiveness In University Students, Ralph W. Redel

Masters Theses

Introduction

Background

In 1938, Travis and Rasmus commented on a particular problem in pathology. They said, "From every angle, an adult with a disorder of articulation presents a much more serious problem than a child with such a defect" (40. p. 218). Their statement is an appropriate current evaluation of the same problem. The American Speech and Hearing Association's Committee on the Midcentury White House Conference reported that the incidence of articulatory disorders was equal, 3.3% for both children and adults in the United States (1). In 1962, Dopheide found that 36 out of 2,087 of the freshman entering Western …

Andrew Jackson: Blackbird Of L’Arbre Croche, Grace Walz

Masters Theses

Prologue

I work very slowly on my lecture. My strength is failing and my eyes are so that I cannot use them by candlelight. I have many pages written with pencil and when I can get them copied in ink, I will send them to you.

My object in trying to have this printed is that it might live after I am dead and finally be adopted as the plan or means to bring about the true development of American Indians.

My days are numbered, as I am entirely unable to do any manual labor, not only from old age …

The Russian Revolution Of 1905 As Depicted By Contemporary American Reports, With Special Emphasis On The "Bloody Sunday" Incident Of January 22, 1905, Patrick Kay Bidelman

Masters Theses

Preface

On Sunday morning, January 22, 1905, a crowd of workers marched through the streets of St. Petersburg, Russia. They were led by a Russian Orthodox priest, Father George Gapon, who had a petition to grievances to present to Czar Nicholas II. As they converged on the square in front of the Winter Palace, they were fired upon by the Imperial troops. The result was a complete military victory for the autocracy and a casualty rate among the petitioners that has caused the incident to go down in history as "Bloody Sunday."

On Monday, January 23, newspapers throughout the United …

And Yet I Have Loved Him: The Judgement Of William Of Saint Thierry On Peter Abelard, Rozanne Elder

Masters Theses

First paragraph:

On the second of June in the year 1140, a Council of the Church in Sens formally condemned as heretical nineteen propositions from the works of Peter Abelard, philosopher, theologian, and teacher of unparalleled popularity. Denying emphatically that his teaching varied in any way from that of the Church, Abelard appealed to Rome, only to have Innocent II uphold the decision of the Council. He upheld the condemnation of Abelard’s works, ordered his writings to be burned, forbade him ever again to teach, and, finally, ordered him to perpetual penance. The condemnation of Abelard can be laid to …

Christianity Encounters Totalitarianism In Germany, Viola M. Gross

Masters Theses

First paragraph:

The German Church of the twentieth century offers a unique opportunity for study. It has twice faced a totalitarian government and has needed to learn to exist and carry on its witness to the Word of God in the face of almost insurmountable obstacles. The purpose of this paper is to contrast and compare the answer of the Church and the Christian to the National Socialists and to the Communists in East Germany, and to determine if possible if Christianity has learned the way through its desperate struggle in this century to continue its task under a hostile …

Study Of The Ste. Genevieve Formation At Selected Localities In Southern Illinois And Western Kentucky, Mahlon Jack Apgar Reinhard

Masters Theses

"The carbonate rocks of the Mississippian Ste. Genevieve Formation were studied megascopically in four quarries--Cave in Rock, Franklin, Three Rivers, and Fredonia Valley--within a small area of the Illinois-Kentucky fluorspar district and in a drill-core from the Cave in Rock Quarry. The rocks were studied microscopically in seventy-four thin sections prepared from samples from the quarries and the drill-core. The Ste. Genevieve Formation is typically an extremely oolitic, fragmentally fossiliferous limestone which is very light gray to white. The megascopic descriptions of the quarry exposures are presented as measured sections and columnar sections. A detailed log of the drill-core is …

A Study Of The Stabilization Of Putnam Silt Loam With Large Organic Cations, George C. Bennett Jr.

Masters Theses

"Laboratory tests were conducted to determine if Aliquat, a quaternary ammonium chloride compound, could be used to change the physical properties of Putnam silt loam. The effects of adding varying amounts of Aliquat to the soil were measured in terms of the results of Atterberg limits tests, the moisture-density relationship, unconfined and triaxial compressive strength, and capillary adsorption characteristics. A small change in the Atterberg limits, the optimum moisture content, and the maximum dry density was noted. An increase in the unconfined compressive strength and a reduction in the moisture adsorption potential was accomplished by the addition of 0.25 and …

Minimization Of Boolean Functions., Don Laroy Rogier

Masters Theses

"A systematic computational procedure is presented for simplifying a Boolean function. The procedure is an extension of the methods presented by W. V. Quine and E. J. McCluskey. Jr. Specific attention is given to the combined use of linear programming and dominance arguments to find a minimum sum of products for large cyclic prime implicant tables"--Abstract, p. ii

Aging Of The Dielectric Properties Of Some Perovskite Ceramics, Hector Troche-Maldonado

Masters Theses

"The effect of aging upon the dielectric constant and the dissipation factor were investigated for a number of lead titanate zirconate ceramics of varying composition. The ceramics investigated have a perovskite type structure. The materials chosen all have tetragonal symmetry at room temperature but are close in composition to materials of rhombohedral symmetry.

Empirical relations were determined for each specimen giving the rate of aging of the dielectric constant (K) and loss factor in terms of the frequency (f) and the elapsed time (t). The range of frequency was l kcps to l mcps; the range of elapsed time was …

The Plastic Behavior Of Beams With Butt Welded Connections., Paul George Hayes

Masters Theses

"The purpose of this study is to determine the length of butt welds required to develop the full plastic section modulus of a 6 WF 20 rolled section of A-36 steel. The members were electric arc welded with LR 6070 electrodes. Two-point loading was used to develop a zone of pure moment with zero shear where these members were joined.

At the cross-section to be welded, all the flange edges were prepared to receive a single-vee butt weld and the webs were prepared for a double-vee butt weld. In all cases the full length of the flange was welded. However, …

Time Optimum Switching Zones In Multiple-Valued Control Systems, Jack Leroy Crawford

Masters Theses

"Present control system theory provides the criteria necessary to bring a second-order single-valued system to rest in a minimum time after a step input. The bang-bang type controller has been developed to obtain this optimum response.

However, existing theory fails to provide the necessary information to obtain the optimum response from a second-order rotational system when multiple values of angular position are allowed. This thesis extends the control theory to include these multiple-valued systems by showing the existence of what are called optimum switching zones. These zones predict which of the infinite number of switching curves in a multiple-valued system …

Investigations Of The Feasibility Of Transporting Ore In Open-Flumes., Kirtikant R. Sheth

Masters Theses

"Considerable effort has been expended and many data are published on developing the technologies of pipeline transportation and hydraulic hoisting. However, comparatively little information is available on the techniques of hydraulic mining, and nearly none ii is reported on conveying slurries in open flumes. For this reason, the author chose to investigate some of the parameters that influence open-flume transport.

It was found that Durand has assembled the findings of several investigators into a simple mathematical expression which is accepted as a standard for designing slurry pipelines. ·Further investigation by the writer revealed that Durand's formula, with only minor modification, …

Optimalization By Peak-Holding, Curtis W. Dodd

Masters Theses

"The problem presented is a study of the peak-holding method of optimalization. This method applies to a system that has an extremum.

After describing how the complete system, consisting of the controller and the controlled system, works; variations in the controller are presented. These variations are changes in the final stage of the controller, the servo. A phase-plane analysis shows how the output of the controlled system varies with its rate of change. Limitations are presented which tell why the system cannot be kept at its peak value at all times. Finally an analog simulation is used to study the …

Solid-Phase Welding Of Nodular Iron To Low Carbon Steel., Scott H. Carriere

Masters Theses

“This paper presents an experimental investigation of the possibility of using solid-phase welding to join nodular iron to low carbon steel. Included is a review of available literature on solid-phase welding, tracing its origin from early Egypt to the present day. There was no previously reported work found on the welding of nodular iron to steel.

Experiments were performed to determine what temperature-pressure combination gave the greatest ultimate tensile strength These experiments resulted in the best welds being produced with an end load of 7000 pounds (35.700 psi) on a half inch diameter sample. The majority of these welds proved …

The Effect Of Plastic Deformations On Grain Boundaries., Jayendra Jamnadas Shah

Masters Theses

"The purpose of this study is to determine the effect of the plastic deformations on the grain boundaries and the grain structure of mild steel. Five beams tested were of A-36 steel and of 6 WF 20 rolled section. Central loading was used to develop a plastic tinge at the cent1:1r.

At the center, where a plastic hinge was formed, the effect of the plastic deformations on the grain structure was severe in all the samples taken from the tension side of all plastically or partially plastically loaded beams. In fully plastically loaded beams this effect had spread on both …

Effect Of Internal Pressure On Compressive Buckling Stress Of A Cylindrical Shell Under Eccentric Loading, Chao-Ping Chu

Masters Theses

“In this paper, an investigation was made of a thin- walled cylindrical shell under compressive load with various eccentricities and internal pressures to study the effect of the internal pressure on the compressive buckling stress of the shell.

So far, theoretical methods have not been devised to solve this problem; therefore, an experimental study was carried out. The experimental results indicated that the buckling load of the shell decreases as the eccentricity increases, that the buckling stress increases as the eccentricity increases, and that the change in buckling stress increases with an increase of internal pressure and is very nearly …
