Addition Of Ketene To Ethylene Oxide, John Philip Friedrich
Addition Of Ketene To Ethylene Oxide, John Philip Friedrich
Masters Theses
"The object of this work was to study the reaction between ethylene oxide and ketene, and if possible, to isolate and identify the postulated γ-butyrolactone. Although the results could hardly be described as completely gratifying, they were at least in a sense positive. Many possibilities remain with regard to further modifications of the experimental work on this problem, however it is the author's sincere wish that this investigation will serve some useful purpose in the future"--Introduction, page 4.
The Thermal Conductivity Of Sodium Chloride At Elevated Temperatures, Howard Martin Brown
The Thermal Conductivity Of Sodium Chloride At Elevated Temperatures, Howard Martin Brown
Masters Theses
"The thermal conductivity of solids has been attributed to a combined effect of the quantized vibration of the lattice points, called phonons, and the flow of valence electrons. In nonconductors the thermal conductivity is due almost entirely to phonons, as was shown by Debye, whereas in metals the conductivity is due mostly to the flow of valence electrons. After Debye, Peierls calculated the lattice conductivity at elevated temperatures using quantum mechanics and demonstrated that it is proportional to 1/T. There are not enough data available to substantiate any theory but what data there are seem to indicate a mixed conductivity …

Correlation Functions For Use In Small Angle X-Ray Scattering, James Edwin Thomas Jr.
Correlation Functions For Use In Small Angle X-Ray Scattering, James Edwin Thomas Jr.
Masters Theses
"Thus, the determination of the structure of the material, and obtaining a distribution function which will enable the theoretical scattering to be predicted is the major problem.
In this work the diffraction material shall be considered to contain scattering regions of identical geometrical forms at such a distance from one another that they will essentially scatter the incident beam independently of their closest neighbor. An effort will be made to determine a correlation function characteristic of these forms, which may be interpreted as a distribution function, that might allow the low angle scattering pattern to be predicted. This correlation function …
A Study Of Tunnel Demolition By Hasty Methods, Richard Lee Bullock
A Study Of Tunnel Demolition By Hasty Methods, Richard Lee Bullock
Masters Theses
"The use of explosives to construct obstacles which impede the enemy or close his routes of communication has long been employed by our armies. They have developed fairly effective methods for destroying bridges, setting up road craters and constructing abatis. However, one phase of obstacle construction, that of tunnel demolition, has been neglected in that no procedures or methods have been formulated which will aid in the proper destruction of tunnels.
At the present time, under the auspices of the Department of the Army, The Missouri School of Mines and Metallurgy is conducting a research program on tunnel demolition. The …
An Investigation Of The Relationship Between Spelling And Articulation, Richard Errol Ham
An Investigation Of The Relationship Between Spelling And Articulation, Richard Errol Ham
Masters Theses
The Background of the Problem
Review of the Literature
The educational importance of speech problems.
There are a number of justification for the existence of speech therapy in the public schools, and some of them have often been expressed in terms of the educational handicap presented by the children with speech defects. Spelling, reading, writing, and speaking often seem to be directly affected by a speech defect. Non-verbal subjects (geography, mathematics, etc.,) can also be affected because they frequently require written reports and oral recitations. In school, the children with speech defects are said to exhibit an overall retardation. Van …

A Study Of The Emission And Absorption Spectra Of Nacl And Kcl Between 100 A And 1000 A, Paul Henry Blackmon
A Study Of The Emission And Absorption Spectra Of Nacl And Kcl Between 100 A And 1000 A, Paul Henry Blackmon
Masters Theses
"This investigation was begun with the idea of obtaining the emission and absorption spectra of NaCl and KCl in the region between 100 A and 1000 A. From these data, it is hoped that useful information concerning the energy levels of these two substances may be obtained.
The vacuum ultraviolet region is rather difficult to investigate because of the necessity of removing all air, lenses and other absorbing material from the light path. Many writers have enumerated the problems involved and some have indicated that much work still needs to be done in the vacuum ultraviolet.
In order to do …
The Velocity Of Ultrasonics In Liquids, Mack A. Breazeale
The Velocity Of Ultrasonics In Liquids, Mack A. Breazeale
Masters Theses
"In acoustics the term ultrasonics is used to refer to those frequencies which are above the range of human hearing; that is, frequencies above approximately 20,000 cycles per second. Since the laws of sound which are valid for the audible range are also valid in the ultrasonic range and since the wave length of ultrasonics is much shorter than that of audible sound, ultrasonic has proved very valuable in the calculation of both the velocity and the absorption coefficient of sound in various media. This is especially notable in the case of liquids, where the velocity of sound is much …
A Fundamental Study Of Clay Drying Using Ware Of Large Cross Section, Robert F. Grady Iii
A Fundamental Study Of Clay Drying Using Ware Of Large Cross Section, Robert F. Grady Iii
Masters Theses
"The drying of clay has been studied extensively in the past by many investigators, some of whom attempted to relate this information to the structure of clay and thereby develop a more vivid picture, while others studied the mechanism of drying in its own right in order to present a useable theory that would allow improvements in the drying operation.
At present the literature is unable to present a theory of the mechanism of drying that is sufficiently general to cover the observed aspects of clay drying. Many and varied mechanisms are presented, but correlation is seldom completely evident between …
An Investigation Of Continuous Steel Beams In The Plastic Range, Robert Adams Shoolbred
An Investigation Of Continuous Steel Beams In The Plastic Range, Robert Adams Shoolbred
Masters Theses
"The purpose of this thesis is to investigate the action of beams in the plastic range. The test specimen will be a 4WF 13 structural shape continuous over three supports having equal span lengths of seven feet. Three types of loading were chosen. The first loading will be concentrated in the center of each span. The second loading will be a concentrated load in the center of one span only. The third loading will be the settlement of the two end supports until a plastic hinge forms at the center support, then the two spans will be loaded with concentrated …
Horizontal Pressures On Retaining Walls Due To Line Surface Loads, John B. Heagler
Horizontal Pressures On Retaining Walls Due To Line Surface Loads, John B. Heagler
Masters Theses
"Among the oldest types of structures with which engineers have had to deal are those which serve to laterally restrain masses of earth, or to prevent earth embankments from assuming their natural angle of repose. This is necessary where space is limited or the natural slope would encroach upon other property. These structures, usually called retaining walls, are subjected to forces, both lateral and vertical due to the pressures exerted by the backfill material and any loads imposed on the backfill material. The first step in the design of the retaining wall is to determine the magnitude, position, and line …
Coloration Of Glass By High Energy Radiation, Thomas L. Nickens
Coloration Of Glass By High Energy Radiation, Thomas L. Nickens
Masters Theses
"Purpose of Investigation: One of the objects of this investigation is to determine the amount of CeO2 required to prevent the discoloration of glass when exposed to gamma radiation. By discoloration, it is meant that there has been a change in the absorption bands of visible light. Another objective is an attempt to prevent the coloration by the introduction of two oxides not previously used. Finally, a theory is presented which could explain why glass containing CeO2 does not change color upon irradiation by gamma rays"--Introduction, page 1.
A Model For X-Ray Scattering From A Free-Volume Liquid, Charles A. Hewett
A Model For X-Ray Scattering From A Free-Volume Liquid, Charles A. Hewett
Masters Theses
"Investigation of the diffraction of x-rays by liquids was begun soon after the well-known work of Friedrich, Knipping, and Laue proved to be of value in supplying information as to the arrangement of atoms in crystalline matter. Friedrich in 1913 reported x-ray diffraction patterns of Canadian Balsam, paraffin, and amber; three years later Debye and Scherrer, in their work on benzene, (among other liquids investigated) showed that the diffraction phenomenon exhibited was one of interference. Still later, in 1922, Keesom and de Smedt reported similar investigations carried out on argon, nitrogen, and oxygen in the liquid state, the results of …

Heat Flow In A Two-Dimensional Steady-Flow System Without Radial Symmetry, George H. Parharoglu
Masters Theses
"As the extent of the science of heat conduction depends on the multiplicity of the boundary conditions that can be applied to the basic differential equation, a particular case in which the use of one set boundary conditions for the development of the general equation for the temperature distribution as well as the the amount of heat flow in a steady-state, two-dimensional heat flow system with a source of heat plased at the center of or along the axis of a cylinder, and without radial symmetry has been the object of this problem. Radial symmetry means the variation of temperature …
