A Light Source To Be Used With A Vacuum Spectrograph, Roy George Woodle Jr.

Masters Theses

"A grazing incidence vacuum grating spectrograph for use in the vacuum ultraviolet was designed and partially constructed by Mr. L. H. Chapin, as a research project for a Master’s Degree. This instrument is designed to photograph the region of the spectrum from 100 Å to 1000 Å. As Boyce pointed out in his exhaustive review, there is much important observational work to be done in this region.

The author of this paper has undertaken to develop a satisfactory source for the region from 100 Å to 1000 Å. This is part of a project to photograph the emission and absorption …

A Lead Sulfide Near Infrared Detection System, William V. Cummings Jr.

Masters Theses

"The infrared region of the spectrum is conveniently divided into the near infrared, which extends from the red end of the visible to about 25 microns, and the far infrared, which continues to an ill-defined division point of approximately 1,000 microns. The near infrared region has been further subdivided on the basis of instrumental techniques so that the particular portion of the spectrum consisting of radiations of wave length up to 3 microns has become known as the photoelectric infrared.

Several types of detection instruments have been designed and perfected for work in the photoelectric region, but new methods and …

Statistical Fluctuation In Radioactive Phenomena, James A. Grundl

Bachelors’ Theses

It is the purpose of this thesis to present a method applicable to an intermediate laboratory course in Modern Physics of establishing the random nature of radioactive disintegrations. The method is fundamentally that used in 1910 by Rutherford and Geiger.

Determination Of Saponification Rate By Change In Hydrogen Ion Concentration Measured With Quinhydrone And Glass Electrodes, Richard Porter

Bachelors’ Theses

The measurement or hydrogen ion concentration is becoming more important in all the fields of chemistry since the states or many chemical systems can to some extent be defined by their hydrogen ion concentration. If the hydrogen ion concentration or a particular solution can be measured accurately, in many cases other important relations and quantities may be determined. Methods or measurement are therefore important instruments or investigation.

When an ester is saponified by an alkali, the hydrogen ion concentration increases as the reaction proceeds. Thus, it the hydrogen ion concentration can be calculated at different intervals of time, some knowledge …

Attempted Separation Of Similar Ionic Species By Means Of Paper Chromatography, Alexander Beresniewicz

Bachelors’ Theses

Chromatosraphy is a comparatively new analytical method which deals mainly with the separation of similar organic compounds. Until now, only a few papers have been published on inorganic paper chromatography. Up to the present time no investigator has made a serious attempt to organize and systematize the large amount of available information in order to clarify the underlying principles.

The author has attempted to investigate the influence of the charge of similar inorganic ions on their separation. In the case of adsorption chromatography, it may generally be stated that ions with higher valence are more readily adsorbed. Such a statement …

Torsional Modulus Of Rupture Of Thick-Walled Magnesium Alloy Fs-1 Tubing, Delbert R. Cox

Masters Theses

"Magnesium is taking a more prominent position in the structure of aircraft, and because of this, it is important that the mechanical properties of the material be understood more fully. In the high speeds of today, the tendency is toward the use of thick-walled tubing instead of the thin-walled tubing with stiffening structures. For this reason, it is of interest to note the characteristics of thick-walled tubing when subjected to torsion.

This thesis was first suggested by a circular letter on proposed thesis titles from the Commanding General, Air Materiel Command, Wright-Patterson Air Force Base, Dayton, Ohio. When interest was …

Square Wave Modulation, Richard Henry Duncan

Masters Theses

"Modulation of a radio frequency carrier can be defined as the variation of some wave parameter such as amplitude, frequency, or phase, in accordance with intelligence to be transmitted. An unmodulated carrier is simply a continuous sine wave and contains no information other than the fact that the transmitter has been turned on. The spectrum of an unmodulated signal consists of a single frequency. Any type of modulation is characterized by the appearance of additional frequencies, known as sidebands. One of the fundamental problems in radio engineering is to reduce the number of sidebands to a minimum and still adequately …

An Application Of The Atomic Distribution Function Of Liquid Mercury, Robert Lee Choate

Masters Theses

"The study of liquids and the knowledge of an adequate description of liquid structure have not advanced as rapidly as it has in the case of solids and gases. In a perfect crystal, the atoms or molecules are held in equilibrium positions by strong intermolecular forces. There are vibrations about these positions, but the translational energy is negligible. The molecules of an ideal gas move independently of each other and the intermolecular potential energy may be neglected. For each of these cases it is possible to derive a partition function from which the properties of the state can be readily …

Radioactive Carbon Labeled Molecules: A Method Of Synthesis, Glen E. Benedict

Masters Theses

"Use of isotopic carbon in determining organic reaction mechanisms is becoming more popular daily. The reasons for this trend are, the increasing availability of intermediate compounds, the increase in isotope handling knowledge, and mechanisms defined by well ordered tracer reactions are considered infallible.

The mechanism of reaction of halo-epoxides has been a point of conjecture for some time"--Introduction, page 1.

A Correlation Function For Liquid Argon, Walter Graham

Masters Theses

"X-ray scattering patterns have given considerable information concerning atomic distributions in matter, both crystalline and amorphous. Work on the diffraction of x-rays by crystals was begun in 1912 by Friedrich, Knipping, and Laue, and much valuable information concerning the arrangement of atoms in crystals has been supplied by this method. Diffraction of x-rays by gases was studied as early as 1911, and work in this field has given information concerning the arrangement of atoms in molecules and electron distribution in atoms. Work on the diffraction of x-rays by liquids was begun by Friedrich who obtained diffraction patterns of Canada Balsam, …

Radiolaria From The Porters Creek Formation (Paleocene, Midway Group) Of Stoddard County, Missouri, Eldridge Sellers Middour

Masters Theses

"Fossil Radiolaria are described and figured from the Porters Creek formation (Paleocene) of Ardeola, Stoddard County Missouri. This is the first detailed treatment of fossil radiolarians from the Gulf Coast area. Thirty-one species are described and figured, all believed to be new, belonging to twenty-four genera. Fifteen families are represented, ten referable to the Legion Spumellaria, five to the Legion Nassellaria. Stratigraphic descriptions or the section at Ardeola is presented, and a discussion of laboratory techniques is included"--Abstract, page 3.

Intermediate Compounds In The Synthesis Of Lignin, Paul Spencer Gakle

University of the Pacific Theses and Dissertations

The synthesis of a keto-aldehyde from salicylaldehyde and benzaldehyde was attempted. The first step was to protect the carbonyl with a non-reactive group.

The bisulfite addition product and the 2,4-dinitrophenylhydrazone of salicylaldehyde were prepared. The methyl acetal, the sodium bisulfite addition product, and the 2,4-dinitrophenylhydrazone of benzaldehyde were also prepared.

The bisulfite addition of both aldehydes was found to be too unstable in the presence of aldehyde was recovered in each case. The methyl acetyl chloride also decomposed. This necessitated finding a more stable group to protect the aldehyde.

The 2,4-dinitrophenylhydrazone was unaffected by treatment with anhydrous aluminum chloride in …

An Analysis Of The Oil Of Echinocystis Fabacea Seeds, Francis Warren Sayre

University of the Pacific Theses and Dissertations

Echinocystis fabaceae, commonly called “Man Root” because of the peculiar shape of the root, not unlike that of a man, finds abundant occurrence in the central valleys of California. This plant, a member of the wild cucumber family, is of particular interest because it is an oilseed plant. The variety agrestis is especially common around Stockton. Other varieties are found throughout the Sacramento and San Joaquin Valleys and in the Coast Range Mountains.

Oils have played an important part throughout history and are continuing to do so in our present economy. An investigation of the oils of Echinocystis fabaceae seeds …

Glacial Geology Of Wabash County, Indiana, William J. Wayne, William D. Thornbury

Department of Earth and Atmospheric Sciences: Faculty Publications

Most of the topographic features of Wabash County are of glacial origin or are glacial deposits eroded by postglacial streams. Shales, limestones, and dolomites, all Silurian, are exposed only along some of the deeper valleys. Four major rivers and six smaller streams in Wabash County flow in glacial sluiceways. Only the Eel and Wabash sluiceways carried large quantities of melt-water. The Eel River valley train occupies an interlobate position, and the Wabash Valley bears evidence of its roles as a sluiceway and as an outlet for glacial Lake Maumee in late Cary time. Three topographic areas comprise the upland part …

The Completion, Adjustment, And Operation Of A Grazing Incidence Vacuum Ultraviolet Spectrograph, William Clinton Johnson-Chamberlain

Masters Theses

"Most gases, and particularly oxygen and nitrogen, are nearly opaque to radiation in the region from about 1800 Å downward to about 2 Å and hence, for spectroscopic work in this region, the removal of these gases is mandatory. Popular usage generally refers to the range mentioned above as the vacuum ultraviolet. That there remains much experimental work to be done in the vacuum ultraviolet has been pointed out by Boyce in his exhaustive survey of vacuum ultraviolet spectroscopy. In order to fill in some of these gaps, Mr. L. H. Chapin, in the, spring of 1950, undertook the construction …
