Physical Properties Of Ellis County Adobe, William G. Read
Physical Properties Of Ellis County Adobe, William G. Read
Master's Theses
Houses made of soil have been built for centuries, but until recently the trend had been away from soil to some other building material. Now, however, adobe is again beginning to be recognized as a satisfactory, reliable building material for our time. Recently, especially in the southwestern part of the United States, a surprising number of dwellers have turned again to earth for their building material. They are following in the footsteps of the early settlers, who constructed many missions and other buildings from sun-dried earth. Many of these buildings, although aged, are still in use or may be viewed …
Determination Of The Proper Mixtures Of Ellis County Soils For Adobe Construction, Buster W. Read
Determination Of The Proper Mixtures Of Ellis County Soils For Adobe Construction, Buster W. Read
Master's Theses
The purpose of this investigation was to determine whether the soils of Ellis County could be used to form waterproof soil blocks that might be used for construction. In the investigation eight soils found in the county were employed and several stabilizers added to each in varying amounts to determine if the specific soils could be rendered waterproof. Several types of paint finishes were tested. The work was divided into three main parts: (1) Survey of Ellis County Soils; (2) Selection of soil material with respect to shrinkage; and (3) Treatment of soils with respect to waterproofing.
A Study Of The Effect Of An Equal Energy Spectrum Upon Metallic Selenium In Vacuo, George Butler Scott
A Study Of The Effect Of An Equal Energy Spectrum Upon Metallic Selenium In Vacuo, George Butler Scott
Master's Theses
Since little has been found in the literature, on the effect of a actinic properties on the conductivity of metallic selenium and on its spectral response when possessing these properties, it was thought noteworthy to construct several selenium cells having low and medium dark resistances and to study them with a view of seeking some correlation between their conductivity characteristics and their prismatic response in vacuo.
The Propagation Of Ten Meter Radio Waves By Vertical And By Horizontal Dipole Antennas, James William Haddock
The Propagation Of Ten Meter Radio Waves By Vertical And By Horizontal Dipole Antennas, James William Haddock
Master's Theses
Radio communication is made possible by means of energy that travels through space from the transmitter to the receiver in the form of electromagnetic waves. These waves move with the velocity of light and differ from visible light only in wave length or frequency. This radiant energy consists of a magnetic field and of an electrostatic field, at right angles to each other and also at right angles to the direction of propagation. Questions explored in this thesis include: 1. Is there a relation between the amount of reflected radio energy and the angle of polarization. 2. If so, which …
Radioactive Properties Of The Subterranean Waters Of Ellis County, Kansas., Verne Lippert
Radioactive Properties Of The Subterranean Waters Of Ellis County, Kansas., Verne Lippert
Master's Theses
Soon after the discovery of Becquerel rays in 1896, tests were made on ordinary matter to see if all matter were radioactive. Although there is evidence to show that all matter is radioactive, to a degree and under certain conditions, it has been found that the greater part of the observable effect is due to traces of radioactive material permeating all matter in general. Thus, radium and its products being the most active of radioactive substances, the surface of the earth is covered with traces of these radioactive substances but the amount varies from place to place. Moreover, determinations of …
Actino- And Thermo- Response Of Molybdenite In Vacuo With Various Colored Lights, John H. Fulton
Actino- And Thermo- Response Of Molybdenite In Vacuo With Various Colored Lights, John H. Fulton
Master's Theses
The purposes of this investigation are to study the reaction of molybdenite cells to light of various colors while in vacuo and at various temperatures. The samples of molybdenite were also subjected to radiant heat in the last part of the experiment, which was undertaken to determine to some extent the amount of thermos-electric effect which was due to thermal radiation in the first part of the investigation.
An Investigation Of The Thermo- And Action- Electric Properties Of Molybdenite, William Otis Johnson
An Investigation Of The Thermo- And Action- Electric Properties Of Molybdenite, William Otis Johnson
Master's Theses
Considerable work has been done on various mineral substances and chemical compounds within recent years to ascertain, if possible, whether the substance possessed any degree of photo- or thermos-sensitivity; and, to determine the characteristics of these responses. Among the most prominent substances which have been tested are selenium, bismuth, antimony, hematite, stibnite, and molybdenite. It was the purpose of this investigation to summarize the phenomena that have occurred within samples of molybdenite under a variety of conditions involving heat, light, and e.m.f.
The Three-Point Gap As A Means Of Control In Instantaneous Photography, Elgin Albert Denio
The Three-Point Gap As A Means Of Control In Instantaneous Photography, Elgin Albert Denio
Master's Theses
In 1926, Wynn Williams investigated the theory of the three-point gap, which phenomenon had been known and utilized for some time but until his investigation was not understood theoretically. This investigation has been divided into two distinct parts: First, when the energy was generated by a large Toepler-Holtz station machine; and second when the energy was generated by a one-kilowatt, 25,000 volt transformer.
A Study Of The Striated Spark By The Method Of Instantaneous Photography, Laurence L. Cruise
A Study Of The Striated Spark By The Method Of Instantaneous Photography, Laurence L. Cruise
Master's Theses
In 1867 Toepler found the existence of a pulse spreading from the region around the spark immediately after it had passed. Since the density of the air in the pulse differs from that of the surrounding gas, the pulse is optically different from the rest of the field and so can be made visible by the “Shadowgraph Method.” Topeler’s work was the first of its kind where an instantaneous view, say of the order of several millionths of a second, of the electric spark was obtained. IN 1926 Dr. Zinszer, while studying the life history of the electric spark by …
