The Effect Of Spontaneous Crystallization Of Some Inorganic Compounds At The Critical Temperature Of Their Solvents, John William Buttrey Jan 1948

The Effect Of Spontaneous Crystallization Of Some Inorganic Compounds At The Critical Temperature Of Their Solvents, John William Buttrey

Masters Theses

"For many years the phenomena which occur at the critical temperature of liquids have been investigated. And since 1912, when Laue and other discovered that a beam of x-rays could be made to yield a diffraction pattern by passing it through a crystal, scientists have been attempting to change the x-ray pattern for various crystals by somehow changing the arrangement of the atoms in the crystal lattice. Harvalik has already shown that crystallization occurs when a solvent reaches the critical point and his work indicates that under these conditions of crystallization there is a change in the crystal pattern. The …


A Microwave Polarimeter, Alfred E. Schwaneke Jan 1948

A Microwave Polarimeter, Alfred E. Schwaneke

Masters Theses

"The dissertation on the following pages may read more like a construction article than an approach to a study of physical phenomena. If so, its purpose is clearly defined. this subject has been studied little from an experimental viewpoint, so one of the main objectives of this writing is to describe the instrument so others may read the article and reproduce this or an equivalent device without a great amount of reading and searching for information on just how to fabricate and mount the parts. No single book or article that I know of covers the inexpensive construction of such …


Hysteresis Loss Of Supermalloy At Different Temperatures, Chester Ray Holland Jan 1948

Hysteresis Loss Of Supermalloy At Different Temperatures, Chester Ray Holland

Masters Theses

"The object of this investigation was to measure the hysteresis loss of supermalloy at different temperatures, and to see if temperature had any effect on hysteresis loss and permeability. The maximum magnetizing current was held constant for all temperatures"--Introduction, page 1.


The Kerr Electro-Optic Effect In Plastic Materials Transmitting Infra-Red Radiation, James Edson Dueker Jan 1948

The Kerr Electro-Optic Effect In Plastic Materials Transmitting Infra-Red Radiation, James Edson Dueker

Masters Theses

"Much work has been done investigating the Kerr Electro-Optic effect and what physical properties of a substance lead to the occurrence of the phenomenon. Information now available indicates a relationship between molecular shape and orientation with the Kerr Effect, hence any added information increases the possibility for finding the exact relationship and the molecular structure of substances. The Kerr Effect, has been used in a number of applications other than for the study of molecular construction of matter. Many applications have been made to form Electro-Optic shutters. This field of work has been increased to include light flash production and …


Radioactivity Of The Pre-Cambrian Section Of The Bourbon, Missouri, Well Core By Measurement Of The Total Hard Gamma Radiation, Paul E. Damon Jan 1948

Radioactivity Of The Pre-Cambrian Section Of The Bourbon, Missouri, Well Core By Measurement Of The Total Hard Gamma Radiation, Paul E. Damon

Masters Theses

"In December of 1947 Mr. Robert Van Nostrand and the writer became interested in the problem of the distribution of natural radioactivity and the applications of radioactivity to geology. A cooperative survey of the literature on the subject was undertaken. Later the writer decided to follow up the survey with a research project. Consultations with Dr. Z. V. Harvalik of the Missouri School of Mines Physics Department, and Dr. E. L. Clark and Mr. O. M. Bishop of the Missouri Geological Survey, followed. The nature of the project was evolved when Dr. Clark, with the consent of the U. S. …
