Study Of Mass Transfer Through Porous, Water-Repellent Membranes, Virendra V. Tanna

Masters Theses

"A new method of desalination using a porous, water-repellent membrane was studied. The membrane utilized surface forces to support a vapor phase in its pores which separated the salt water from fresh water. The method used a vapor pressure difference across the membrane as the driving force for mass transfer of water from the salt water phase to the fresh water. This vapor pressure difference was obtained by maintaining a temperature difference between the two liquid phases.

The experimental data and results indicated the feasibility of vaporization through porous, water-repellent membranes. The flux of water through a membrane made of …

A Study Of The Development Of A Heuristic Program That Solves Symbolic Laplace Transformation Problems, Arthur E. Zackrison

Masters Theses

"A medium-speed general purpose digital computer (IBM 1620 Model II) was programmed to solve symbolic Laplace transformation problems. Although the applied mathematician and modern engineer has many uses for the symbolic solution of a problem, the potential of symbolic manipulation by a computer has not yet been sufficiently developed to help them because of many problems. This paper discusses the program and based on the author’s experience with it’s [sic] performance, clarifies the position of several of these difficulties and reaches some conclusions concerning computer solution of such problems"--Abstract, page ii.

Catalytic Effects On Radiation-Induced Polymerization Of Methyl Methacryalate, David E. Bartine

Masters Theses

"A study has been made of the effect of Kaolin clay particle size and acidity on the degree of radiation-induced polymerization of methyl methacrylate. The results indicate that the degree of polymerization varies with the clay particle size, and that the amount of polymer produced is influenced by the pH of the clay"--Abstract, page ii.

The Effect Of Concentration On The Viscosity Of Polyisobutylene Solutions, Lung-Yu Chou

Masters Theses

"In the past twenty years the viscosity of dilute polymer solutions (i.e., where the solute molecules are far apart) has been investigated in great detail, both theoretically and experimentally. The viscosity characteristics of such systems are well-understood.

Only a few studies have been made of the effect of concentration on the viscosity of polymer solutions in the concentration range where the polymer molecules begin to overlap. This range of concentrations is important in practical applications such as dry spinning of fibers, cross-graded automotive motor oils and in many industrial formulations where polymers are used to thicken solvent vehicles. Development of …

A Periodic Dielectric Rod Antenna, Robert C. Peirson

Masters Theses

"The periodic dielectric rod antenna structure under consideration consists of identical dielectric rod sections of radius a meters situated on a common axis. These sections are of length 1₁ meters and are separated in free space by distance 1₂ meters.

Field analysis employing Floquet's theorem, in terms of the exemplary TM₀₁ circular mode, gives expressions for the various field components and an eigenvalue equation. Digital solution of this eigenvalue equation establishes the location of propagation bands as a function of frequency. Such bands are characteristic of any periodic wave guiding structure."--Abstract, page ii.

The Effect Of Non-Linearity On A Frequency-Modulated Wave, Tzu-Tien Hung

Masters Theses

"A method is presented for finding the effect of a nonlinear characteristic of a device on a wave which is frequency modulated by only one sinusoidal modulating wave. The distortion in the output has been found by passing a frequency-modulated wave (which is represented by a summation expression for the spectrum components) through a non-linear circuit having a Fourier series represention of its Characteristic. Two cases have been considered: (1) a nonlinear output-input characteristic, and (2) a non-linear amplitude-frequency characteristic"--Abstract, page ii.

Structure Contours On The Top And Base Of The M Bed, The Relationship Of Mineralization To Structures, And The Variation Of The M Bed Thickness In The Tri-State District, Missouri, Kansas And Oklahoma, Arvind A. Desai

Masters Theses

"Regional structure and thickness of a single horizon, the M bed, have been studied in the Tri-State district by picking the top and base of the M bed in the logs of 557 selected drill holes and contouring this data together with the aid of local detailed structural information available for individual mining fields. Structures determined from these data were compared to the positions of mined mineralization to determine the control of regional structure upon the localization of ore. Variations in the M bed thickness were compared to the positions of fields of mineralization to examine possible spatial relationships which …

Slope Stability Analysis Of A Fissured Glacial Clay, Byron G. Walker

Masters Theses

"A slope in an over-consolidated, fissured clay was analyzed by the Swedish Method of Slices.

Values of cohesion (c) and angles of friction (Ø) were determined by three different types of direct shear tests (undrained, drained and residual).

Factors of safety (functions of c and Ø) indicated that the direct shear test parameter gave a factor of safety approximately four times that represented by failure conditions in the field. Drained tests gave a factor of safety nearly 2.3 times the value represented by field conditions. The conclusion is made that these two tests are of limited value for slope stability …

Synthesis And Structural Determination Of Intermetallic Compounds In The Fe-Ho System, Gerald J. Roe

Masters Theses

"The intermediate phases in the holmium-iron system were investigated by means of X-ray diffraction and metallographic examination. The intermediate phases identified by X-ray diffraction data were HoFe₂ , HoFe₃ , HoFe₅, and Ho₂Fe₁₇.

A new intermediate phase, HoFe₃, was found. HoFe₃ was indexed as hexagonal with lattice parameters of a = 5.084 Å and c = 24.45 Å, and was thought to be of the space group R3̄̄m.

HoFe₂ was formed by a peritectic reaction and its solidus was estimated to be between 1325°C and 1340°C. suggested to be a congruent melting intermetallic compound with a melting point below 1340°C. …

The Thermodynamics Of The Zno-Fe₂O₃-Fe₃O₄ System, Dennis George Dreyer

Masters Theses

"A study was made of the ZnO-Fe₂O₃-Fe₃O₄ system at 1200ºC using oxygen pressures between 0.1 and 1x10⁻⁴ atmospheres. The results of this study were used to calculate the activities of ZnO, Fe₂O₄, and Fe₃O₄ in the spinel solid solution region of this ternary system. The activities of ZnFe₂O₄ and Fe₃O₄ across the pseudo-binary system were then calculated. The activities of the components in both the ternar and pseudo-binary systems exhibited large positive deviations from Raoult's Law, being more pronounced at the higher Fe₃O₄ content. The free energy, enthalpy, and entropy of mixing of the pseudo-binary system ZnFe₂O₄-Fe₃O₄ at 1200ºC were …

Phase Shift Analysis Of Protons Elastically Scattered By 016 Near EP = 8.3 Mev, Glenn D. Westin

Masters Theses

Chapter I

Introduction

The study of the resonances in the scattering cross section of the p + O¹⁶ reaction can reveal information regarding the energy levels of the compound nucleus F¹⁷. The analysis is simplified because of the zero spin of the O¹⁶ nucleus. Also, the low binding energy of the proton added to O¹⁶ allows examination of the low-lying energy levels in F¹⁷.¹ The reaction has been intensively investigated at the University of Wisconsin in a series of experiments using an electrostatic accelerator as a source of protons.

An Investigation Of The Relationships Between Judgements Of Esophageal And Artificial Larynx Speech Made By Sophisticated And Naïve Judges, Gerald Robert Moses

Masters Theses

The Background and Purpose of the Study

Introduction

Laryngectomy, the surgical removal of the larynx, is performed to save life threatened by a carcinomatous condition of the larynx. This surgical procedure is also performed when necessitated by accident, injury or other pathologies of the larynx. (35).

There are living, in the United States, an estimated 15,000 to 20,000 individuals who have undergone surgical removal of the larynx due to the carcinomatous condition of that organ (33). It is probable that the total population of laryngectomized persons would exceed this number if statistical information were available concerning the number of laryngectomies …

An Investigation Of The Maturation Of Articulation Of Elementary School Children, Thomas D. Marshall

Masters Theses

The Background and Purpose of the Study

Introduction

Developmental studies of speech (12, 13, 24) have indicated that the growth of articulation skills in children follows a definite pattern, with the vowels being first mastered, then the consonants, and finally, the consonant blends. Studies generally agree that the normal child acquires essentially adult articulation by eight years of age. It may be expected, then, that in the early elementary grades, immature articulation skills are not unusual in normal children, and that at higher grade levels, immature articulation skills are relatively less common. Mills and Streit (11), in a survey of …

An Investigation Of Adaptation To The Delayed Auditory Feedback Effect By Normal Speakers, Nelson H. Bormann

Masters Theses

Introduction

Research is being conducted in numerous areas of interest in an effort to better understand the functionings of the various speech deviations. One promising area of investigation is studying speech production as an automatic-control system or a servosystem. Interest in studying the theories of servosystems was greatly stimulated by the work of Nobert Wiener, who first formulated and developed the science of cybernetics. An integral aspect of cybernetic theory is the concept of controlling the behavior of a system by monitoring and evaluating the system's own output. Wiener stated that, in its simplest form, "...the feedback principle means that …

Interests, Attitudes And Personality Patterns Of Undergraduate Students In Speech Pathology And Audiology, Sandra Mary Henderson

Masters Theses

Chapter I

The Problem and Its Background

Introduction

Over the past several decades there has been increasing interest in the occupational choices of men and women, and the interests and attitudes associated with various professional groups. Since occupations are becoming increasingly more specialized, employers and educators have found that those people who perform best in the position of their choice are those who exhibit certain interests and attitudes with regard to their occupation. Colleges emphasize the necessity of counseling in order to enable students to effectively choose general areas of concentration. The fields of study chosen by students are a …

Great Britain And The Balkan Crisis Of 1875-1878, Carol Zainfeld Becker

Masters Theses

Introduction

For years Great Britain had followed the time-honored doctrine in foreign affairs of maintaining the balance of power which meant

to resist by diplomacy or arms the growth of any European State at once so formidable and so potentially hostile as to threaten our national liberties, the security of our shores, the safety of our commerce or the integrity of our foreign possessions.

With the defeat of Napoleon in 1815 and the establishment of the Metternichian concept of the concert of Europe, Britain's historic determination to preserve the balance of power gave way to a new attitude in foreign …

Anglo-American Isthmian Diplomacy And The Clayton-Bulwer Treaty, George W. Shipman

Masters Theses

Introduction

The Panama Canal is one of the major commercial waterways of the world and, furthermore, it is vital to the defence of the United States. ·Before this canal could be constructed, it was necessary to persuade the British government to give up its right to share with the United States the building of an isthmian canal. The Clayton-Bulwer treaty of 1850 had provided that neither the United States nor Great Britain would carry out the project singly. Later through the Hay-Pauncefote treaty Great Britain agreed to abrogate the Clayton-Bulwer treaty and allowed the United States alone to build and …

The Utilization Of Artillery And Mortars As Infantry Support Weapons In The Chaco War, Charles John Goodall

Masters Theses

I. The Background of the Conflict

In the summer of 1932, while the world's attention was focused upon Japanese aggression in Manchuria, a border skirmish in the upper reaches of the Plata valley ignited a conflict which could not be extinguished by the good offices of the Pan-American Union or the peace-making machinery of the League of Nations. The prize in question, nearly one hundred and fifty thousand square miles of savanna and swamp, would be minuscule in comparison with the territorial acquisitions of the dictators of that era, but to the two politically unstable and highly nationalistic nations contesting …

Helianthus Annuus - The Separation And Identification Of A New Fatty Acid, Donald C. Gruber

Masters Theses

Introduction

The term "fatty acids" was first applied principally to saturated, monobasic carboxylic acids and especially to long chain acids derived from animal and vegetable oils. As time passed and the knowledge of natural fats increased, polyunsaturated, hydroxy, keto and branched chain acids were also found as constituents of these fats and oils and these also came under the heading of fatty acids. Even acids containing alicyclic substituents were found.

More recently the term 11 fatty acid" has been applied to include saturated and unsaturated monobasic carboxylic acids and several other series of substituted acids having carbon skeletons similar to …

United States Dollar Diplomacy In China During The Taft Administration, In Suk Ro

Masters Theses

I. Introduction

The fundamental aims of a nation's foreign policies are national security and the achievement of national objectives through diplomacy. At different periods in American history, the foreign policy of the United States has been designed to advance a variety of aims. It is possible, for example, to speak of missionary diplomacy, moral diplomacy, military diplomacy and dollar diplomacy. The latter characterizes one phase of economic foreign policy in which the administration of President William Howard Taft represents a dramatic turning point. The foreign aid programs of the period after World War II, such as the Marshall plan and …
