An Energy Solution For Vibration Characteristics Of Free Thin Cylinders, Dale Elmer Leanhardt

Masters Theses

"In this report the flexural vibrations of the walls of free, thin, circular cylinders are considered. Theoretical expressions are developed for the natural frequencies by extending the approximate energy method of Arnold and Warburton to the free-free case. Furthermore, the developed expressions are shown to apply, as special cases, to the fixed-fixed and simply-supported cylinders analyzed by Arnold and Warburton. The energy solution for free-free cylinders is checked both experimentally using a 3500 pound-force, 5 to 2000 hertz, vibration exciter and numerically using the well documented SABOR IV-DYNAL finite element program. While the derived energy method accounts for any prescribed …

Dolomitized Pahasapa Limestone (Mississippian), Northeastern Sector Of The Black Hills, South Dakota, Petrography And Geological Setting, Abdullatif Najjar

Masters Theses

"The carbonates of the Mississippian Pahasapa Limestone in the northeastern sector of the Black Hills outcrops were examined in order to ascertain specific characters of the lithology in this area where the formation is predominantly a dolomite in contrast to adjacent areas where it is mainly a limestone. The Pahasapa seems to be uniform in thickness at the study areas and maintains a thickness of about 550 feet. Because of poor exposures, usually at the base or top, complete sections could not be measured. Much of the Pahasapa consists of coarsely crystalline dolomite containing varying proportions of crinoid plates, gastropods, …

Fossil Otoliths Of Some Lower Cenozoic Perciform Fishes Of The Gulf Coast, Mostafa Juma Salem

Masters Theses

"Nineteen perciform species from the lower Cenozoic and one Recent species are described, and included under eight genera. The main characters that were considered as generic are the outline of the sagitta and the structure of the sulcus. The other features of the otolith were regarded as secondary in importance. The characters that were believed to be valuable at specific level are almost the same as those for the genus but in more detail. These species are considered to be within the Suborder Percoidei. The fossil species of "Nemipterus" were put in the Family Nemipteridae as they resembled the Recent …

A Measurement Of The Capture Coefficient And Of The Vapor Pressure Of Co₂ From 69ºk To 80ºk, Michel Louis Chouarain

Masters Theses

"The capture coefficient of CO₂ gas at 135ºK on a surface of CO₂ at temperatures between 69ºK and 80ºK is measured by means of quartz crystal microbalances. The vapor pressure of CO₂ is measured in the same range of temperature"--Abstract, page ii.

Contractor Quality Control: A Method Of Construction Inspection, John Scott Treadwell

Masters Theses

"It has become apparent in recent years that the United States Government's construction contract supervision and administration procedures are causing an increase in contractor claims and disputes and that the system itself is becoming prohibitively expensive. To deal with some of these problems, the Department of Defense is attempting to implement a new approach to construction inspection--Contractor Quality control. Under the Contractor Quality Control System the majority of the standard contract inspection and testing responsibilities are placed on the contractor, and the Government relinquishes its traditional step-by-step inspection and testing procedures and withdraws to a position of contract surveillance. The …

Lysis Of The Rhizobiaceae, Craig Richard Baumrucker

Masters Theses

The following members of the Rhizobiaceae were tested for their lytic response to various treatments: Agrobacterium tumefaciens, Chromobacterium violaceum, Rhizobium phaseoli, Rhizobium trifolii, Rhizobium lupini, and Rhizobium japonicum. Lysis was observed in spent growth media and as a function of saline concentration, pH, buffer composition, disodium (ethylenedinitrilo) tetraacetate (EDTA) concentration, and lysozyme.

Cells were harvested by centrifugation, washed, and resuspended in various treatment solutions. The lytic response was followed spectrophotometrically.

The different responses of the six cultures was applied to a summation of reclassification proposals evolved through modern taxonomic techniques such as DNA homology …

The Halogen And Uranium Content Of Sedimentary Rocks, Tektites, Impact Glasses, And Obsidians, Victor J. Becker Jr.

Masters Theses

"The iodine and uranium concentrations in sedimentary rocks were measured by irradiating the samples in a neutron flux, radiochemically separating iodine, and ß-counting the resulting activity. The values obtained for uranium are in good agreement with previous estimates of the uranium content in sedimentary rocks. The values obtained for iodine define a distribution pattern similar to that reported for chlorine and bromine, in contrast with the distribution pattern previously reported for iodine in sedimentary rocks. The concentrations of chlorine, bromine, iodine and uranium were determined in tektites, obsidians and impact glasses by neutron activation. The uranium content found in tektites …

Interactions Between Selected Pigment Producing Bacteria Isolated From Sewage, Leslie Alexander Lakie

Masters Theses

"Pigmented bacteria have been of interest to the microbiologist for several years. The pigmented organisms in sewage have been known to gain predominance, but no investigations have been made to determine whether the pigment assists the organism in gaining predominance. During this study a number of bacteria which produced a water soluble pigment were isolated from sewage. These bacteria were grown in shaken flasks using tryptone Glucose extract broth as a medium. Growth studies of the bacteria in pure and mixed culture were performed to determine if the pigment could affect another bacteria's growth. Studies were also performed using the …

Calculation Of Eddy Current Loss Of A Disc, Kou Quen Chang

Masters Theses

"A method is presented to calculate the eddy current losses of a uniform disc with an opening in the center and excited by a circular current loopage First, the disc is subdivided into smaller concentric rings, then the self-inductances, the mutual inductances between these smaller rings, the mutual inductances between the excitation coil and the smaller rings, and the resistance of the rings are calculated. Next, the eddy current flowing in each ring is obtained by solving a complex matrix equation of the form [X] [I] = [V] where X is the impedance matrix, I is the eddy current matrix, …

Petrology And Petrography Of The Croweburg Coal, North-Central Missouri, William Keith Wedge

The Justification Of Jehan Petit: A Fifteenth-Century Attempt To Justify Tyrannicide, John C. Parsons

Masters Theses

The Justification of Jehan Petit was composed as an attempt to explain the murder in 1407 of Louis, duke of Orleans, by his cousin John the Fearless, duke of Burgundy. The murder was politically necessary for John to be able to dominate the French government while the king, Charles VI, was mad.

Petit attempted to prove that the duke of Orleans had been a tyrant, and that the murder was justifiable as tyrannicide. The validity of Petit’s theory demanded that he be able to prove Louis' tyranny. In so doing, he departed radically from the medieval concept of a tyrant …

The Metropolitan Area Concept And Its Development In Lima, Peru, Jose Luis Mesa

Masters Theses

Introduction

The paucity of comparative urban research is of course not due to indifference or lack of foresight on the part of social scientists, but to the absence of comparable or standardized information from one country to another and to the technical problems presented by this deficiency. The units of observation themselves, that is "cities" and "towns," have not been standardized, nor have we had information on a representative sample of these for the world as a whole. Furthermore, the structure of urban communities has changed with increasing urbanization, a change that has gone further in some countries than in …
