Data Retrieval In Mass Spectrometry By An Optical Coincidence System, Cynthia Helmintoller O'Donohue
Data Retrieval In Mass Spectrometry By An Optical Coincidence System, Cynthia Helmintoller O'Donohue
Master's Theses
The object of this work was to develop an information storage and retrieval system for use in mass spectroscopy. The information to be stored was the compound's name, the mass spectrum, and distinctive physical and chemical properties. It was desirable that the system be one that could be used in the mass spectral laboratory. At the time this project was initiated, no system for mass spectroscopy had been developed with the characteristics of simplicity, rapid retrieval, and practicality of use in the laboratory without elaborate and space consuming equipment. Thus, a system was needed to aid the laboratory personnel in …
A Thermogravimetric Study Of Polyvinylidene Chloride In Polymers, Charles Edward Singleton
A Thermogravimetric Study Of Polyvinylidene Chloride In Polymers, Charles Edward Singleton
Master's Theses
In the manufacturing of thin films such as cellophane, polymers employed as coatings greatly improve film functionality. Polymers such as polyvinylidene chloride, polyvinyl chloride, polyvinyl acetate and many others are used as coatings or components of coatings designed to improve the functionality of a film. Selection of polymers with properties that will meet the requirements of the finished film product is a continuing process of film manufacturers. Physical and chemical characterization of the polymer along with coating functionality are the factors involved in the selection. Chemical composition is the most important factor affecting polymer characteristics and must be known if …
Peracid Oxidation Of 3-Phenylindene, Christopher Peter Johnson
Peracid Oxidation Of 3-Phenylindene, Christopher Peter Johnson
Master's Theses
Indene oxide (indan, 1,2-epoxy; indene 2,3-oxid is first recorded in the literature in 1919. This compound was formed in practically quantitative yield by the treatment of indene bromo hydrin in ether with powdered potassium hydroxide. At this time Van Loon also reported the preparation of indene oxide by mechanical shaking of an anhydrous, ethere!al solution of the bromohydrin with finely powdered potassium hydroxide. The desired product was obtained in a 92-97% yield by this method. Indene oxide has been prepared in a similar manner from trans-2-chloro-l-indanol by treatment "with soda," distillation of the acetone in vacuo after 15 hours, and …
The Artistic Deformation Of Reality : An Ideological Portrait Of Tyranny In Tirano Banderas And El Señ̃Or Presidente, Roebrta Wynne Cohen
The Artistic Deformation Of Reality : An Ideological Portrait Of Tyranny In Tirano Banderas And El Señ̃Or Presidente, Roebrta Wynne Cohen
Master's Theses
Tyrants speak with many voices, bold many poses, and cast many shadows, but inevitably all wear the same face--the tragic face of tyranny itself. Many artists have painted the portrait; few have captured the essence of its tragedy. Valle Inclan and Asturias, each in his own way, depict the world of tyranny as grotesque and absurd in order to show the tragic condition of man. It is my intent to describe and analyze this grotesque world of tyranny, as portrayed in Tirana Banderas and Senor Preeidente; to compare the techniques used by each writer to create this world; to interpret …
An Attempt To Measure The Diffusion Of Aluminum Into Natural Aluminum Oxide, Charles Edward Galaspie
An Attempt To Measure The Diffusion Of Aluminum Into Natural Aluminum Oxide, Charles Edward Galaspie
Master's Theses
The goal of this research was to investigate the diffusion of aluminum ions in natural aluminum oxide grown under atmospheric conditions. The basis for the approach employed here had been developed earlier by J. H. Christian and H. L.Taylor. However, these authors studied the diffusion of aluminum ions in an oxide grown in a pure oxygen atmosphere. They utilized a glass slide upon which aluminum metal was deposited in vacuo (10-11 Torr). Oxide was then allowed to grow on this metal by back-filling the vacuum with pure oxygen to a pressure of 40 to 50 m Torr while infrared …

Milton And Cambridge : A New Look At An Old Attitude, Roy S. Riner
Milton And Cambridge : A New Look At An Old Attitude, Roy S. Riner
Master's Theses
From the insights cleaned from current research into John Milton's years as an undergraduate and a graduate student at Cambridge University, this writer has found an overwhelming amount of material dedicated to pointing out Milton's total lack of affection for that university. For the most part, those statements bearing on Milton's dislike for Cambridge are unequivocal. For example, one scholar has remarked that John Milton departed from the University in 1632 "weary and disguised" with the medieval, unbearable antiquated methods of the place. That same scholar continues with the statement that Milton's attitude toward Cambridge was "uniformly unfriendly" and that …
Colonial Independence Of Feeding Among Zooids Of The Ectoproct Lophodella Carteri (Hyatt), Leonard M. Bahr
Colonial Independence Of Feeding Among Zooids Of The Ectoproct Lophodella Carteri (Hyatt), Leonard M. Bahr
Master's Theses
Possible interactions of feeding between zooids of colonies of the freshwater ectoproct Lophopodella carter! were investigated. Suspensions of Euglena gracilis at a concentration of 558x103 cells ml-1 were cleared by L. carter at a rate of 2.7 x 10-3 ml min-1 zooid-1 for15 minute periods. The rate of ingestion of E. gracilis by L. carter was independent of the size of colony and decreased exponentially with time, declining to about one third the original rate in 60 minutes.

The Theory And Development Of A Dyeing Machine Employing The Rotary Pendulum, Ashley Paul Smith
The Theory And Development Of A Dyeing Machine Employing The Rotary Pendulum, Ashley Paul Smith
Master's Theses
A review of dyeing methods for carpet is made with the objective that the requirements of a new machine could be formulated. The proposal for a new machine is made in the light of the above review using a pendulum as the basic component. A theory is developed for the motion of the pendulum which is mounted on a rotating disc, and the experimental work built on theory is outlined. A prototype machine based on the rotary pendulum mechanism was used to dye impregnate carpet.

A Spectrophotometric Study Of The System: Cobalt--2,2,8,8-Tetrakis (Hydroxymethyl)-3,7-Diaza-1,5,9-Nonanetriol, Pauline Frances Fones
Master's Theses
Spectrophotometric studies or solutions or 2,2;8;a. tetrakis(hydroxymethyl)-3, 7-diaza-1,5.9-nonanetriol, (HOCH2),3CHNCH2CH(OH)CH2NHC(CH2OH)3, with cobalt (II) gave evidence of complexes having metal-ligand ratios of 1:2 and 1:3. Complexation appeared nearly complete at pH 8 or greater. Between pH 8 and pH 11, the positions of the maxima in the absorbance spectra remained essentially constant and no precipitation was observed. The 1:2 complex formed rapidly, while the 1:3 complex formed more slowly, requiring one to two weeks to reach equilibrium, after which the solutions remained unchanged over a period or several months. Evidence …
The Effect Of Poor Discipline On Achieving A Grade Point Total Consistent With Ability At Tuckahoe Junior High School, John Wayne Traylor
The Effect Of Poor Discipline On Achieving A Grade Point Total Consistent With Ability At Tuckahoe Junior High School, John Wayne Traylor
Master's Theses
There has been a great deal of speculation and controversy over discipline in the schools of the world. The causes and effects of poor discipline have been discussed, and much has been written on both subjects. The public schools of America are in the peculiar position of being greatly affected by poor discipline. Being a public institution open to all citizens, the schools have to meet the problem and have to find ways of combatting it in order to maintain an efficient operation in line with the standards of excellence set by the public which sustains them.
It was the …

An Evaluation Of The Effectiveness Of Moderator Variables Developed By Three Techniques, James Porter Tucker Jr.
An Evaluation Of The Effectiveness Of Moderator Variables Developed By Three Techniques, James Porter Tucker Jr.
Master's Theses
In a recent article, Hobert and Dunnette (1967) maintained that compared to the Absolute-difference and Algebraic-difference techniques Quadrant Analysis should yield the more effective moderators. Their assertion was based on the reasoning that more homogenous subgrouping should yield moderators with increased sensitivity to error. The present study was carried out as an empirical investigation of their assertions. Further, the design of the study permitted an investigation of moderator function.
The total sample (n=333) of male college students was randomly divided into a developmental sample and a cross-validation sample. Employing the aforementioned techniques a total of five moderator scales were developed …
