The Faraday Rotation And Dispersive Doppler Effects In The Ionosphere At Oblique Incidence, Charles Roland Baugher Ii

Masters Theses

"Integral equations for the isotropic and anisotropic ray path of a radio wave propagating through the ionosphere are developed. These equations assume a spherically stratisfied ionosphere and are equivalent to a detailed ray-tracing process. A method is devised to utilize these equations in the evaluation of combined Faraday rotation and dispersive Doppler data from earth satellites for subionospheric electron content. The method, which corrects for horizontal ionospheric gradients, is applied to data from the Explorer 22 satellite and some preliminary results are discussed"--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 …

The Construction Of A Multi-Threshold Foil For Fast Flux Measurements, Michael Henry Holkenbrink

Masters Theses

"The construction of a multi-threshold foil for fast neutron flux measurements is investigated. The factors governing the selection of the materials are the energy response of the given reactor, the half-life of the daughter, the prominent gamma ray emitted during decays, the power level of the reactor, the availability of adequate cross section data, and the alloying properties of the composite foil. A ternary system was chosen as a compromise between the difficulty of fabrication and the amount of information gained from one foil. The particular system chosen was In- P- Fe. The threshold reactions of these elements are In¹¹⁵ …

The Anodic Oxidation Of Maleic Acid, Larry D. Gilmartin

Masters Theses

"The purpose of this investigation was to determine the mechanism of the anodic oxidation of maleic acid on platinized-platinum electrodes at 80⁰C. Current density-potential studies were conducted varying the parameters of maleic acid concentration and pH. The faradaic efficiency of the oxidation of maleic acid to yield CO₂ was determined. The effect of temperature on current density was also studied to determine the activation energy for the reaction. The oxidation of maleic acid occurred only in acidic solutions. The faradaic efficiency was found to be approximately 97 ± 5 per cent. A linear Tafel region was found which had a …

Tectonic Analysis Of Mare Humorum On The Lunar Surface, Adnan Said Abul-Husn

Masters Theses

"Morphology and internal structures of surface features of the Mare Humorum area were interpreted from photographs and topographic maps. The postulated origin of certain features is based on analog comparisons with known terrestrial features. The laws of crate ring and a newly developed computer program were applied to two representative classes of craters to determine the possibility of a meteoritic impact origin. Some of the craters formed by meteoritic impact and others, including those with a radius larger than 10 Km, probably resulted from volcanic activity.

Mare Humorum formed from centripetal subsidence followed by extensive lava eruptions. Spacially related rilles …

Fast Flux Measurement By A Single Multi-Threshold Foil, Kenneth Lawrence Cage

Masters Theses

"The purpose of this investigation is to determine the fast neutron spectrum by use of a single multi-threshold foil. The foils and the elements which constituted the foils were selected by the following criteria: availability of adequate cross-section data, energy dependence of the given reaction, gamma radiation emitted during decay and the half-life of the daughter. The two foils selected were an In-Fe- P pellet, and ALCOA 2509 (Al-Ni). The gamma spectrum of each constitute was stripped from the composite spectra using a least-squares fit. The activation results were utilized to calculate the fast flux using the weighted orthonormal method. …

Anodic Dissolution Of Silver In Aqueous Solutions, B. W. Jong

Masters Theses

"The purpose of this investigation was to study the anodic dissolution of silver in various electrolytes to determine if there existed any deviations from Faraday’s law in nitric acid-silver nitrate solutions. The effect of small additions (10^-4 and 10^-5 N) of Cl^-, SO₄⁼, and CrO₄⁼ on the apparent valence and dissolution potential was also studied. Current densities were varied from 0.00 to 0.07 amp·cm^-2.

Based on the observed apparent valences and a grey film containing metallic particles on the anode surface, it was concluded that deviations from Faraday’s law …

Plastic Design Of Steel Frames For Minimum Weight, I-Chen Hung

Masters Theses

"The purpose of this study was to develop a method for weight minimization of the plastically designed frame, braced normal to its plane of action, and composed of prismatic steel members. The method accounts for the non-linear relationship between weight and moment capacity for both beams and columns. Reduction in the pure-bending fully-plastic moment in the presence of axial loading and both beam-column instability and overall frame instability due to sidesway are taken into account. Provision is made for minimization of frames employing standard sections as well as for frames whose built-up members may be chosen from a continuous spectrum. …

An Investigation Of Consolidation On Compacted Partially Saturated Clarksville Soil, Ma-Tai Matthew Chen

Masters Theses

"The Terzaghi theory of consolidation and the assumption of his theory, pore pressure and effective stress, secondary compression and rheology were all reviewed and discussed. Eight compacted unsaturated samples made from Clarksville silty clay (CL) under different compaction efforts and moisture contents were subjected to consolidation load increments. Each load increment was maintained for 24 hours. An extra compacted sample was loaded for one month to investigate secondary compression.

From e-p curves, five settlement vs. compacted embankment height curves were derived for different compaction effort and moisture contents. These curves may be of practical use, when checked by field measurements …

Geology Of The Acari Iron Mining District Arequipa, Peru, Raul Alejandro Zevallos

Masters Theses

"The Acari Iron Mining District, part of a tilted uplifted fault block, comprises an area about 300 square kilometers, in the southern part of the coastal belt of Peru. It is in the foothills of the western range of the Andes and it is dominantly formed by granodioritic and granitic intrusive rocks which belong to the Andean batholith of Cretaceous-Tertiary age. The intrusive rocks are overlain by a central, elongated, northwest trending band, of metasedimentary and volcanic rocks

The magnetite deposits of Acari district are long, dike-shaped bodies, which fill two systems of fractures in the granodiorite intrusive, located in …

A Method For Approximating A Specified Impulsive Response, Charles A. Gross

Masters Theses

"Given a system's time response, y(t), to a unit impulse, a method is presented by which an approximating function y*(t) may be determined. It is inherent in the method that the transform function Y*(s) is rational. The poles of the approximating function are found from the coefficients of a difference equation, which is made to fit the given data in a least mean square error sense. The zeros are determined by a procedure based on the fact that at a given time the given function and its approximate derivatives are known. Accuracy and implementation of the method are investigated primarily …

Some Effects Of A Non-Uniform Specific Charge Upon Space Vehicle Parameters, Geary L. Leger

Masters Theses

"An equation is derived for the space-charge-limited current of an ion beam when there exist n different species of ions in the beam. The combined effects of non-uniform specific charge and space-charge-limited conditions upon thrust, propellant flow rate, and payload ratio are studied, and a graphical investigation and interpretation is made.

This thesis will show that: (1) The existence of multiply ionized species in an ion beam will increase the space-charge-limited current over that expected in a beam composed of purely singly ionized ions, (2) the thrust produced by the ion beam is independent of the non-uniform specific charge distribution, …

History

Uses of Biologically-derived Products in Painting

Throughout history man has relied heavily on plant-derived materials in the production of paintings. Plant products have been used to fulfill each of the material requirements of painting. The ground or surface upon which an artist applies paint -is usually of plant origin, such as woven fabrics and paper. The ancient Egyptians painted on canvas (from Linum usitatissimum L.), papyrus, (from Cyperus papyrus L.), and wood (Lucas, 1934:149-150, 201-203; Laurie, 1910:17, 31-32).

At the time of Theophilus leather parchment, preferably of horsehide, was popular for painting (Bazzi, 1960:13). After parchment, walls and wooden …

Virginia Evangelicals And The American Revolution: The Role Of The Baptist, Presbyterian, And Methodist Clergy, William Jennings Terman

Masters Theses

I. Religious Factors as a Cause of Revolution

Standard history books contain little or nothing of the documentary material which would relate religion to the factors contributing to the American Revolution. References to social, political, and economic causations abound, but only occasional statements concerning the influence of religion are found, and among these the role of the Anglican, Roman Catholic, and Quaker persuasions receives most attention. Yet the involvement of the evangelical churches was significant enough to merit separate, intensive studies. It is the object of this essay to investigate the involvement of the Methodist, Presbyterian, and Baptist groups in …

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 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 …

The Private Session In Michigan Council-Manager City Government, Dale H. Poel

Masters Theses

Introduction

Norton Long has stated that "...under the deceptive uniformity of an apparently similar legal structure, a wide range of actual variance appears in the 'constitutions' of our local government."¹ The concern of this study is one part of that wide range of variance: the private and/or informal sessions held by councils in Michigan council-manager cities. These sessions are part of that variance which, if not understood, must lead to tentativeness and uncertainty in generalizations on the local government process. They would include any meetings of the council and manager other than the formal public meeting. Instances in which …

A Study Of The Fluctuation Of Some Blood Chemical Constituents In Relation To The Reproductive Cycle Of The Mallard Duck, Edward H. Decker

Masters Theses

Introduction

The purpose of this study was to determine normal levels of several blood chemical constituents (the mineral sodium, potassium and calcium and the organic substances serum cholesterol and serum albumin) for the female mallard duck (Anas platyrhynchos) and to examine their relationships as a possible index to reproductive development.

Much research has been done on the chemical composition of the avian egg and only those constituents which are of concern in this study will be discussed in detail. According to Romanoff (1949), studies of the chicken egg have shown that only a few mineral elements are present in relative …
