Porosity-Permeability Relationships Of Unconsolidated Sands, Robert Marchel Ponder

Masters Theses

"Unconsolidated sand reservoirs containing oil and gas present difficult problems to the petroleum engineer. Among these problems is that of the determination of the reservoir porosity to facilitate oil and gas reserve and evaluation calculations.

This problem is especially difficult because, to the author's knowledge, no method has been devised to obtain a core sample of the unconsolidated sand that retains the same porosity and permeability characteristics in the laboratory as it had underground. As a result, the petroleum engineer must rely upon empirical methods of calculating the reservoir porosity when the sand is not consolidated.

Many investigators have attempted …

An Experimental Study Of The Effect Upon The Current Distribution And Radiation Pattern Of Crossbars On Yagi Receiving Antennas, Gerald F. Sinnamon

Masters Theses

"The development and widespread use of radar systems in World War 11, and the post-war television boom, has brought about a large amount of investigation in antenna arrays. One of the types of antennas commonly used on radar systems during the early part of the war, and one which finds wide usage today as a television receiving antenna, is the well known Yagi antenna...

Since television antennas are usually mounted out of doors, the antenna must be made mechanically strong to prevent whipping or twisting due to wind, and to prevent sagging due to icing or to its own weight. …

An Investigation As To The Uses Of The Topographic Map And Improvements Desired By The General Public, George O. Boeckman

Masters Theses

"The demand for topographic maps from hunters, fishermen, vacationers, professional engineers etc, has been increasing with each passing year. In 1940 people bought some 700,000 copies of topographic maps. In 1946 sales had jumped to well over 2,000,000 copies. Civilian use of these maps by veterans has contributed substantially to the tremendous expansion of demand for maps since World War II. In recent years, the quality of topographic maps has been greatly improved by refinements in methods and by the use of aerial photography in map compilation. This advancement, and an ever-increasing demand from engineers, geologists, and many others for …

Autographic Determination Of Thermally-Induced Linear Changes In Ceramic Bodies, William Dean Mckee Jr.

Masters Theses

"The determination of changes in length of ceramic compositions as a function of temperature is frequently required in ceramic research and testing. With the use of an observer, excellent means are available for determination of changes in length over moderate ranges of temperature. However, the extended period required for some tests makes desirable the automatic recording of length change as a function of temperature.

There has been in use in the Ceramic Engineering Department a furnace arranged for determination of length changes; this furnace, shown in Figure 1, is so arranged that change in sample length causes linear displacement of …

An Investigation Of End-Anchorage And Performance Of Sr-4 Strain Gages On A Prestressed Concrete Beam, Howard W. Nunez Jr.

Masters Theses

"In recent years there has been brought to the attention of engineers and architects a new medium of construction---prestressed concrete. Reinforced concrete has long been recognized as a satisfactory material for use in the construction of buildings, bridges, highways, tanks and other structures. However, most concrete designers will concede that this material has many drawbacks. For instance, in a simple beam of rectangular cross-section, roughly only one half or the concrete is relied on to resist compressive forces. The tensile strength of the concrete is considered to be zero, and steel bars or rods must be inserted to carry the …

The Effect Of Grain Size On Shearing Strength Of Sand, Keyhan Samimi

Masters Theses

"The object of this study is to determine experimentally the effect of definite grain size on the shearing characteristics of sandy soils. As it will be discussed in detail under the article - The Mechanics of Shear, the shearing characteristics of sandy soils depends on many factors such as grain size and shape, soil structure and relative density, the water content of soil. An attempt is made throughout the entire investigation to determine the effect of definite grain size on the shearing value and the angle of internal friction under the dry and saturated conditions. Furthermore, the results of shear …

A Study Of The Dissolution Of Titanium In Acids With Ammonium Fluoride Added, Charles Burroughs Gill

Doctoral Dissertations

"Titanium can no longer be considered a rare metal, even though the modern era of its production came into being only a few years ago. The first discovery of titanium was in 1791 by an English clergyman, the Reverend William Gregor, and the name titanium became universally adopted when so called by a German mineralogist, Martin Klaproth, who rediscovered titanium three years later. Not until 1887 was the relatively pure, 75 percent, metal prepared by L. F. Nilson and O. Pettersson, whose experiments were repeated in 1910 by M. A. Hunter. Hunter is given credit for producing the first metallic …

Determination Of Progressive Corrosion Of Clay Flux Blocks, Ved Prakash Maheshwary

Doctoral Dissertations

"The Problem. Corrosion of refractories by molten corrosive liquids like molten slags and glasses is of general occurrence in those parts of the furnaces where they come in contact with the liquids. The life of a furnace generally depends upon the progressive rate of corrosion of the refractories by the slags and glasses. There have been various methods used by the investigators to ascertain the useful life of a refractory product before its use in the furnaces, but the problem is so complex that even after decades of research work by the research engineers and technologists a satisfactory and easy …
