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 …

Physics, Chapter 1: Fundamental Quantities, Henry Semat, Robert Katz

Robert Katz Publications

Physics is a fundamental science dealing with matter and energy. By convention, the subject matter of physics has been divided into such topics as mechanics, heat, sound, light, and electricity. In addition to these general classifications, present-day physics includes atomic physics, nuclear physics, solid-state physics, chemical physics, biophysics, and many other subdivisions. It is impossible to include all aspects of physics in a single definition or paragraph, and to distinguish physics clearly from its nearest neighbors, the other physical sciences-astronomy., chemistry, and geology.

Physics [Complete Work], Henry Semat, Robert Katz

Robert Katz Publications

This book is intended for students of science and engineering; it aims to develop both an understanding of the important concepts of physics and some analytical skill in the solutions of problems. The mathematical level of the book is such that it may be used by students who are taking a course in calculus concurrently.

The notations and methods of the calculus are introduced early in the text, beginning with the concept of a derivative in the discussion of motion, and are then extended to more complex problems as the student progresses both in physics and in mathematics. Vector algebra …

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 …

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 …

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 …

The Mineralogy And Paragenesis Of The Lone Star Deposit, Santa Fe County, New Mexico, Lawrence K. Lustig

Earth and Planetary Sciences ETDs

The Lone Star deposit is located in La Bajada Canyon in western Santa Fe County, New Mexico. The exposed sedimentary rocks of the area range in age from the Cretaceous to recent. Four unconformities are present which are the result of erosional levels established during the Tertiary. The host rock of the deposit is the Cieneguilla liburgite formation. The Cieneguilla consists mainly of thin embedded limburgite flows and conglomerate of Miocene age. The Lone Star deposit lies in this conglomerate at a depth of approximately 150 feet from the top of the Cieneguilla.

The Synthesis Of Some Methyl Substituted 3,4-Benzpyrenes, Jules L. Adelfang

Chemistry and Chemical Biology ETDs

3,4-Benzpyrene (I), a highly carcinogenic hydrocarbon was first isolated from coal tar in 1933 by Cook, Hewett, and Hieger. Interest in the relationship of structure to carcinogenic activity and correlation of physical properties with carcinogenic potency led to the synthesis of several monomethyl 3,4-benzpyrenes during the decade following the isolation of the parent hydrocarbon. Detailed reviews concerned with the various phases of this research have been prepared. Recently the synthesis of the 1-^2, 7-^3, 8-^(2,5), and 10-^4 methyl-3,4-benzpyrenes completed the series of reported monomethyl derivaives.

Rhenium Catalysis I. Hydrogenation And Hydroformylation Using Rhenium Carbonyl Compounds ; Ii. Hydrogenation Using Catalysts Obtained From The Reduction Of Perrhenates With Metals In Aqueous Solution, Terry G. Selin

Theses and Dissertations

The purpose of this work was to investigate the catalytic activity in both hydrogenation and hydroformylation reactions of rhenium preparations which have not been previously characterized. Rhenium pentacarbonyl was prepared in good yield from rhenium heptoxide and carbon monoxide. The optimum conditions for preparation were 25 hours per gram of dry rhenium heptoxide at 250° under 3000 psig. (initial) of carbon monoxide. Rhenium chloropentacarbonyl was prepared in 62% yield from potassium chlororhenite and carbon monoxide at high temperatures and pressures. The iodopentacarbonyl was prepared in 29% yield from potassium perrhenate, methyl iodide, and carbon monoxide. The preparation of rhenium hydrocarbonyl …

The Preparation And Catalytic Properties Of Rhenium Blacks Obtained By Reduction Of Re(Vii) In Anhydrous Ammonia And Amines With Alkali Metals, David William Seegmiller

Theses and Dissertations

The purpose of the investigation was to determine the catalytic activity of rhenium blacks obtained by reduction of rhenium salts in alkali metal-ammonia or amine systems. A review is presented on the chemical, physical and catalytic properties of rhenium, and on the rhenide ion, on the nature of the alkali metal-liquid ammonia system, and the reduction of metallic salts therein. The first reduction system studied was that obtained by dissolving sodium in liquid ammonia. The salts reduced in this system were KReO_4, Re_2O_7 and NH_4ReO_4. The reduction of KReO_4 was unsuccessful, and the heptoxide was difficult to handle. The product …

Chemosynthetic Microorganisms In Leaching Sulfide Minerals, A. Keith Jameson

Theses and Dissertations

This investigation showed that a single bacterium was capable of sulfide oxidation in exposed ore bodies. This single bacterium was isolated and characterized. It exhibited different characteristics than any previously known organism. It was found to be a chemosynthetic autotroph. An optimum nutrient concentration was determined for pyrite oxidation. The nutrient concentration was determined for pyrite oxidation. The nutrient contains only a source of phosphate and nitrogen. Urea was found to be a better source of nitrogen than ammonium sulfate which had previously been used. The effect of various organic compounds on the oxidation of pyrite was observed. Glucose and …

The Isomer Distribution In The Sulfonation Of Iodobenzene, Joseph A. Knight

Theses and Dissertations

Using the isotope dilution technique, the distribution of isomers was determined when iodobenzene was sulfonated with sulfur trioxide in liquid sulfur dioxide. The active isotope was S^35. Before this distribution could be established, it was necessary to prepare the pure isomers of iodobenzenesulfonic acid. These were prepared by diazotization of the corresponding aminobenzenesulfonic acids. Since o-aminobenzenesulfonic acid was not readily available, it was necessary that it be synthesized before the diazo reactions could be carried out. Considerable work has been done on the development of a method whereby the bromobenzenesulfonic acids could be synthesized and obtained in pure form. Some …

The Chemical Behavior Of Iodine At Tracer Concentrations, Henry Morris Eiland

Chemistry and Chemical Biology ETDs

Radiochemistry was introduced as a separate branch of chemistry by Pierre and Marie Curie in 1898. The first radiochemical process consisted of the separation and identification of the new element Polonium from the uranium ores pitchblende and chalcalite. It is significant that this process involved an amount of material so small that it could be detected only by its intense radioactivity. In the last half-century radiochemistry has developed into a field of ever increasing diversification.

A Study Of Current Noise In Cokes, Carbons, And Graphites, Robert J. Lanter

Physics & Astronomy ETDs

This study shows that current noise occurs when there is a deviation of Ohm's Law, i.e., when the applied voltage and resultant current are no longer proportional. Since most, and perhaps all, cases of occurrence of frequency and current dependent noise are associated with non-linear devices, e.g., semiconductors, diodes, vacuum tubes, insulators near breakdown, it seems reasonable to seek a mechanism involving non-linearity as an important feature. Even though it may not be justifiable to seek a single mechanism to explain all of the occurrences of current noise, nevertheless, the fact that in cases studied and discussed herein …

A Cloud Chamber Study Of Penetrating Showers In Aluminum, Copper And Lead, James Francis Kenney

Physics & Astronomy ETDs

In recent years, much work has been done in the investigation of high-energy nuclear collisions in various materials. The purpose of these investigations is to gain a better understanding of nucleon-meson-nucleon interactions at high energies. Laboratory accelerating devices are capable at the present time of attaining energies which are still very low in comparison to the upper limit of the cosmic radiation energy spectrum. As a result, these investigations are best carried out by using the very hard component of the cosmic radition as the primary particle of the collision.

A Pulse Length Analyzer, Paul Scheie

Physics & Astronomy ETDs

For experiments involving small scintillators and for experiments involving scintillator telescopes, the circuitry may closely resemble that used with geiger counters. However, if it is desired to make use of the variation in the signal amplitude in a large scintillator, some means must be found to deal with a wide range of amplitudes. The scintillator employed in the experiment to which this work relates is a tank 10 feet in diameter that contains 300 gallons of activated toluene; light of the scintillations is collected by a 16 inch photo-multiplier tube that is located on top of the tank.

A Chemical Ozone Measuring Radio Sonde, Alan W. Peterson

Physics & Astronomy ETDs

The Vertical distribution of atmospheric ozone has been determined spectroscopically either from surface observations or from balloon-borne spectrographs sent aloft. These spectrographic techniques have several disadvantages. Surface observations of the "Umkehr Effect" give only a rough distribution, four or five points for the entire atmosphere.

The Geology Of The Tecolote Hills Area, Lincoln County, New Mexico, Donald E. Rawson

Earth and Planetary Sciences ETDs

The Tecolote Hills in the north-central Lincoln County, New Mexico, consist of Permian, Triassic, and Cretaceous sedimentary strata intruded by early Tertiary (?) sills, dikes, and laccoliths. A partial section of the Permian Yeso formation, measured thickness 380 feet, is exposed and is overlain conformably by the Glorieta sandstone member of Permian San Andres formation. This sandstone thins, at least locally, to the south and intertongues with San Andres limestone. The maximum thickness of the Glorieta sandstone is about 215 feet. It is overlain by a 300-foot thickness of San Andres rocks, further divisible into a lower limestone member and …

A Study Of The Density And Molecular Species Of Polonium And Tellurium Vapor, Angelo L. Giorgi

Chemistry and Chemical Biology ETDs

The purpose of this investigation was to determine the nature of the species of polonium and tellurium in equilibrium in the vapor phase at temperatures ranging from 422 degrees to 1013 degrees C. for polonium and from 512 degrees to 880 degrees C. for tellurium. Such information was based on measurements of the variation of vapor pressure and vapor density with temperature. The results of this investigation suggest that both polonium and tellurium exist as diatomic molecules in the vapor phase over the aforementioned temperature ranges.

Studies Of The Chemistry Of Systems Involving Water, Hydrogen Peroxide And Plutonium (Iv) Nitrate In Tri-N-Butyl Phosphate, Lawrence J. Mullins Jr.

Chemistry and Chemical Biology ETDs

The reaction of tri-n-butyl phosphate (TBP), with water and hydrogen peroxide is studied by means of distribution experiments. The solubility of water in TBP-hexane, at low TBP concentrations, is consistent with the premise that H₂O•TBP is the principal solvate species formed at low hydrogen peroxide concentrations. The distribution data at high hydrogen peroxide concentrations indicate that another species such as H₂O₂•TBP is also present. The reaction of hydrogen peroxide with plutonium(IV) nitrate in TBP is studied by a spectrophotometric method. A complex is formed which contains one plutonium atom and two peroxy-oxygen atoms. The …

Correlation Of Reef Calcarenites Of The Pennsylvanian Paradox Formation, San Juan County, Utah, Jack Jordan

Earth and Planetary Sciences ETDs

This thesis is a summation of lithologic analyses of three stratigraphic sections: the Danvers 1-X Harris-Federal test, the Honaker Trail locality, and the Raplee locality in San Juan Canyon, San Juan County, Utah (FIg. 1) In these localities, the Paradox Formation as defined by Wengerd and Strickland (1954, p.2169) has been studied, inasmuch as the formation is known to contain limestone bioherms ("reefs") (Wengerd, 1951) in conjunction with biostromal strata.

A Radiochemical Investigation Of Short-Lived Selenium And Bromine Fission Products, James Edward Sattizahn Jr.

Chemistry and Chemical Biology ETDs

From a sample of uranium bombarded with neutrons, Hahn and Strassmann, in 1939, separated four radioactive products which followed alkaline earth chemistry and were therefore tentatively attributed to isotope of radium. Each of these products decayed to a daughter activity which could be precipitated along with lanthanum; the daughter activities were then assumed to be isotopes of actinium. Subsequently, by accepted methods of fractional crystallization and precipitation, the "radium" and "actinium" isotopes were identified unequivocally as isotopes of barium and lanthanum, respectively. Within a relatively short time there were found more such radioactive products, which were identified as isotopes of …

Behavior Of Indium At Tracer Concentrations, Katheryn L. Lawson

Chemistry and Chemical Biology ETDs

The increase in number and availability of radioisotopes that can be produced in the carrier-free state has offered practical means of investigating the chemical behavior of substances at extremely low concentrations. The working region of concentrations, which may extend to less than 10^-14 molar, is generally fixed only by the half-life of the radio-element and the nature of the radiation.
