A Cell-Center Distribution Function For Liquid Argon, Arthur M. Soellner

Masters Theses

"A theoretical expression for a cell-center distribution function was developed using a fundamental statistical mechanics approach. A free volume picture of the liquid was used with each atom located in a spherical cell formed by its nearest neighbors. Cell-center density distribution curves were obtained for liquid argon for temperatures of 84.4°K, 91.8°K, 126.7°K, 144.1°K, and 149.3°K and for argon gas at 149.3°K, and a comparison made with the experimental atomic distribution curves obtained by Eisenstein. For the first two temperatures a sharper, more definite structure was predicted by the cell model. For the remaining four temperatures, with the assumptions made, …

Geology Of The Northeast Portion Of Des Arc Quadrangle, Iron And Madison Counties, Missouri, Wesley Dean Weixelman

Masters Theses

"A geological investigation of the northeast portion of Des Arc Quadrangle in southeast Missouri was completed during the summer of 1958. Exposed Precambrian rocks include, from oldest to youngest, undifferentiated purple rhyolites with an interlayered tile-red rhyolite, andesine basalts with interlayered tuff, and an andesite. A diabase dike intrudes the lower purple rhyolites. The purple rhyolites account for about ninety-seven percent of the Precambrian exposures. Exposed Paleozoic rocks belong to the Bonneterre formation and include three members: (1) Lower Brown dolomite; (2) Light Gray dolomite with Tom Sauk limestone and arkosic sandstone and conglomerate facies; and (3) Upper Brown dolomite. …

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 …

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 …

Liesegang Rings, Robert Edward Young

Masters Theses

"Although the discovery of the "Liesegang Rings" phenomenon was made sometime before 1855 little was done in the way of study or experimentation until 1896 when R. E. Liesegang discovered that if a crystal or strong solution of silver nitrate is added to a gelatin gel containing dilute potassium chromate, the resulting precipitate of silver chromate is not continuous, as might be expected, but forms a discontinuous periodic pattern. This pattern follows a geometric progression law, x_n = akⁿ, where x_n is the position of the n^th ring, and a and k are constants. K …

The Use Of Chelating Agents In Inorganic Analysis, Richard K. Vitek

Masters Theses

"The objectives of this investigation were; (1) to improve the existing gravimetric method of analysis for palladium with dimethylglyoxime by adding EDTA to the solution to chelate interfering metal ions: (2) to develop a new and better gravimetric method of analyses for palladium with a different organic ligand and employing a chelating agent such as EDTA or NTA to remove the interference of foreign ions"--Introduction, page 2.

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 …

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 Background In A Long Sensitive Time Wilson Cloud Chamber, Donald A. Rinker

Masters Theses

"A long-sensitive time Wilson Cloud Chamber has been built and tested. A usable sensitive time of 2.5 seconds has been achieved by the use of a system of five expansion valves, the first three of which are used to obtain the sensitive time and the final two to continue the expansion at a supersaturation slightly less than critical in order to allow all droplets formed to grow in size and fall into the liquid. This system of continued expansion, coupled with delayed recompression, has been proved to reduce the background density in the chamber to an average operating value of …

Paragenesis Of The Minerals In The Einstein Vein Madison County, Missouri, Robert P. Stevens

Masters Theses

"Selection of the Problem: The mineralogical problem of determining the paragenetic sequence of minerals in the Einstein vein, Madison County, Missouri, was suggested by Dr. O. R. Grawe, who previously had supervised a thesis by Joel Pomerene dealing with the geology of the area. Although considerable attention has been given to the mineralization along the vein, a specific study of the paragenetic relations has not been made. Paragenesis has, however, been discussed by others in papers dealing with the geology of the area. Such a study is extremely important in the establishment of a hypothesis of origin, and hence, an …

An Improved Long Sensitive Time Wilson Cloud Chamber, Clarence W. Mettenburg

Masters Theses

"The discovery of numerous new particles in recent years such as mesons and hyperons causes one to speculate about the possible existence of still other particle types….

A cloud chamber seems to be a most suitable means of detecting particles ionizing less than the minimum ionization of the electron because it is capable of detecting almost all the ions produced. The cloud chamber makes it possible to study not only a wide range of ionization but also many fine details of track structure which would go unnoticed by other means of detection….

With the information and experience gained by the …

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 …

Transference Numbers Of Concentrated Manganous Chloride Solutions, Marshall L. Severson

Masters Theses

"Electrolytic conduction differs from metallic conduction only in the nature of the carrier of the current. In the case of metallic conduction the carrier is electrons. The passage of an electric current through an electrolyte occurs only by the movement of ions of opposite charge moving in opposite directions under an applied potential. The current carried by a particular ionic species is a direct function of the concentration, the charge on the ion, and the ionic mobility. A transference number is the fraction of the total current a given ion carries in a particular electrolyte undergoing electrolysis. The sum of …

Some Thermodynamic And Structural Properties Of A Linear Chain Of Atoms, And Extension Of The Model To Two- And Three-Dimensional Cases, Hari Gopal Mukerjee

Masters Theses

"An attempt has been made in the present work to derive some thermodynamic and structural properties of a linear chain of atoms (under somewhat idealized conditions) moving in the fields of nearest neighbours and assuming a parabolic well in the interaction of pairs within the range of relative movements. The equation of state and other formulas derived are applicable only to the linear model which could be considered as a simplified form of one-dimensional crystals in the form of chain-like molecules of rubber-like substances. An attempt has also been made to extend the model to two- and three-dimensional cases"--Introduction, page …

Detection Of Low Energy Positive Ions By Scintillation Methods, Graydon J. Hanson

Masters Theses

"This thesis deals with the feasibility of efficiently detecting low energy positive ions, those with energies of less than several hundred electron volts, using phosphors.

The scintillation technique, first used visually and greatly improved in the last ten years by the use of a photomultiplier tube, has greatly advanced detection in high energy fields. The photomultiplier is capable of delivering milliampere pulses of current of short duration and these can be registered directly by the many electronic devices currently in use.

Extensive work has been done with phosphors which scintillate under which energy bombardment, due in part to their wide …

A Probe For Measuring Ultrasonic Pressures, Robert F. Rohrer

Masters Theses

"In the study of acoustics, the term ultrasonics is defined as those wave motions that have frequencies greater than about 20,000 cycles per second. The characteristics of a sound wave at any point in a medium can be regarded as completely defined when the amplitude, frequency, and phase of its Fourier components are known.

Sound measurements at their best are difficult. In the last few years sensitive linear microphones and electronic amplifiers have become available. Still, there are two difficulties of prime importance with their use in a sound field. First, there is the precise, absolute calibration of the equipment …

Internal Friction In Manganese Copper Alloys, William Paul Dixon

Masters Theses

"The study of the physical properties of the manganese-copper alloys is an intriguing one. These alloys show promise of usefulness in instances in which high internal friction is needed to reduce the noise and vibrational stresses at resonant frequencies of a part of a machine. The purpose of this study has been to learn more about the internal friction of manganese-copper alloys as a function of temperature, stress amplitude, frequency, time, and past history of the specimen. From this information the mechanism for absorption of vibrational energy is proposed, or at least some progress has been made toward its determination. …

A Geological Study Of The Irvine Ranch Area, Johnson And Campbell Counties, Wyoming, Gale E. Butterfield

Masters Theses

"The discovery of uranium in the Powder River Basin, Wyoming, by the U. S. Geological Survey in 1952 has lead to an extensive exploration program throughout the region by both private and governmental agencies. This report is a geological study of an area in the southwestern part of the basin.

Geological and radiometric mapping carried out as a part of this report indicated several areas of uranium occurrence. Some of these occurrences warrant tests by drilling.

An Investigation Of The Internal Friction Of Manganese-Copper Alloys, Ed. (Edward) Sickafus

Masters Theses

"Internal friction is defined as the ability of a vibrating solid to convert its mechanical energy of vibration into heat, even when completely isolated from its surroundings. (1) The most familiar manifestation of internal friction is the damping of a freely vibrating body, such as a torsional pendulum. Another example would be the increased width of the resonance peak observed when a nonelastic body is forced to vibrate over a spectrum of frequencies.(2) Internal friction manifests itself in numerous ways, and we will here be concerned with the first example cited and the potency of data gained in studying the …

Thermal Conductivity Of Sodium Chloride Within The Temperature Range 375°K To 637°K, Paul E. Ohlsen

Masters Theses

"The transport of heat in dielectric solids is attributed entirely to lattice waves whereas in metals there is in addition a transfer by the flow of valence electrons. The thermal conductivity of a non-electrical-conductor is limited by a number of scattering processes giving rise to thermal resistances. Scattering results from impurity atoms and from vacancies and dislocations within the crystal structure and from the interaction of the lattice vibrations amongst themselves. Scattering also occurs at the boundaries of the crystal. The thermal resistance of an ideal crystal at low temperatures is due almost entirely to boundary scattering and at high …
