Lanthanide Shift Reagents Involving Crown Ethers, David J. Long

Theses

Complexes between lanthanide nitrates and the cyclic polyethers 18-crown-6 and dicyclohexano-18-crown-6 have been synthesized; the reactions occur rapidly and in high yield. The crown ether-salt complexes have been characterized by melting point, infrared and ultraviolet spectrophotometry, conduct­ anee ana 1 ysis, and nuc1ear magnetic resona nee spectrometry. NMR sp ctra of uncomplexed and complexed crown ethers were identical; I tt'le uncomplexed salts were more soluble in NMR solvents than were the complexes. In most cases the crown ether-salt complexes are usable shift reagents and induce greater shifts than do the uncomplexed lanthanide salts in both proton and carbon magnetic resonance …

The Settling Of Particles In A Square Contained Medium, Richard S. Matyas

Theses

Stokes' Law, has been standardly utilized to calculate the terminal velocity of falling particles. However, the limitation of Stokes' Law is that it does not take into account the container walls and their resulting drag forces. Extensive work with additional drag due to cylindrical container walls has been examined by many investigators. The classical and earliest is the well know Ladenburg Correction which cannot be utilized with non-cylindrical containers. This experimental thesis examines the analog of the Ladenburg relationship for a square container. This experimental thesis was undertaken to experimentally determine the value of the constant K₁ for a …

An Investigation Into The Effects Of Gloss And Smoothness On Legibility, Donald Perlman

Theses

This study on legibility takes a different approach than the studies that precede it. Standardized test targets (ISO Characters) were used as the measurement device instead of the various means used previously. This was done to keep the test more objective. Twelve papers of different gloss and smoothness values were tested with two groups--college students and senior citizens. These experiments were done under controlled conditions with the only variable being the paper. The average results from the legibility readings were correlated against the physical properties of the paper samples. The results of this study showed a 2 and 4% correlation …

A Consciousness Simulation Model, R. Edward Mitchell Jr.

Theses

The thesis titled "A Consciousness Simulation Model" by R. Edward Mitchell (1977) explores the theoretical design of a digital model aimed at simulating human consciousness. The model is structured around a collection of independent processing modules that mimic various human cognitive and emotional processes. These modules include components for thought selection, ego/achievement, memory, and emotion processing, which interact with one another in a fashion that simulates aspects of human thought and behavior.

Mitchell's primary goal is to develop a system that could behave more like a human, particularly in communication and decision-making processes, to improve human-machine interaction. The thesis highlights …

Infrared In-Process Densitometer, Miroslav Piskacek

Theses

The development chamber for an infrared, in-process densitometer, which will monitor and display a characteristic curve of a standard sensitometric strip during development, was designed. The monitoring radiation is to be emitted by a sequentially pulsed array of IR diodes (RCA SG1009A) and detected by an array of solid state detectors (UDT-450 Photodiode/Amplifier combination). The output of the detectors, corresponding to IR transmission, is to be scanned, electronically converted into density, and displayed. Electronic scanning assures that processes with subminute total development time can be monitored. Optical losses of the system were estimated, and a model of the optical system …

An Approach To Energy Conservation In A Manufacturing Industry, William Polignano

Theses

The approach attacks the problem of control and planning of energy usage via three major categories. These areas are: detection, forecasting and reporting of energy usage.

To initiate any energy program the first step, is the identification of the areas that use the most energy, thus allowing detailed studies to be concentrated in these energy-intensive areas. The author has attempted to show which areas are energy-intensive in his employer's plants.

The second step is the accurate forecasting of energy usage. The author has attempted this via an econometric forecasting model that accurately predicts energy usage based on direct labor hours …

Point Of Operation Safeguarding - A Metal Forming System Approach, William Baker Eaton

Theses

The mechanical power press in its application in the metal stamping and forming industry has been misinterpreted as a selfcontained metal forming system. Examination of the production routines involving the press show that this machine is actually only one elemental component of the metal forming system and not the total production unit.

Authoritative codes and standards pertinent to the mechanical power press have reflected this misinterpretation by not including system considerations in their contents. These omissions have resulted in the providing of safeguards which do not properly reflect the particular characteristics of the metal forming system to which they are …

The Guarding Of The Principal Metalworking Machines : The Techniques, Need, And Responsibility, Peter James Schwalje

Theses

This thesis examines the guarding of the principal metalworking machines employed in the economy. The machines selected for consideration comprise the bulk of metal processing equipment utilized in the basic fabrication and manufacturing processes. It has been intuitively recognized that this equipment has been involved in a significant quantity of industrial accidents by the very nature of the hazards created by their normal use. Consequently, a need to develop some form of guarding or means of operator protection is called for.

In order to examine this question the principal metalworking machines are enumerated, their basic operating characteristics set forth,, and …

Sparsity And Decoupling In Load Power Flow Analysis, Kenneth Nazimek

Thermal Decomposition Products Of Kynol And Nomex With Reference To Structure And Toxicity, Shaker H. El-Sherbini

Theses

The purpose of this investigation was to study the combustion products of KYNOL and NOMEX as a fire retardant fibers. From the quantitative analysis data of the combustion products, the polymer structure is discussed and the property of thermal stability is explained.

From the analysis of the combustion products, the toxicity indices for the two fibers are determined. It is found to be 0.1 for KYNOL and 0.71 for NOMEX. This can be interpreted to mean that, if one gram of MIDI, is decomposed and the combustion products were diffused in one cubic meter of air, the probability of dying …

An Experimental Study Of Separation Of Binary And Ternary Gas Mixtures By Parametric Pumping, Stephen E. Belsky

Theses

An experimental study of gas parametric pumping is presented which examines the purification of helium using silica gel to remove the impurity carbon dioxide. Low gas flow rates are used to allow adequate time for equilibrium to be approached, assuming intraparticle diffusion is the controlling mass transfer step. By varying the cycle time, at long cycle times, the effect of penetration length (a function of dynamic capacity) is indicated. Also, at low cycle time, the effects during pressure changes become more significant.

Using low flow rate improves separation effectiveness if evaluated at equal dynamic capacity. When using low flow rate …

Air Control In A Newark City Subway Station, Robert H. Burch

Theses

During the period from June, 1974 to January, 1976, 103 24-hr samples of the air at the Broad Street station of the Newark City Subway were collected by cascade impactor. The size distributions (based on Stoke's equivalent diameters) of the total suspended particulate matter were determined gravimetrically. Samples were also analyzed by atomic absorption spectrometry to obtain information on the concentration of iron, manganese, lead, copper, zinc, and cadmium in each size fraction. The geometric mean particulate level was found to be more than twice the Federal Ambient Air Quality Standard and triple that of ambient Newark air sampled nearby. …

Vapor-Liquid Equilibrium At Low Pressures : Correlation Of Binary And Prediction Of Multicomponent Data, Norman I. Silverman

Theses

The Wilson equation is chosen as typical of the new correlations for activity coefficients gaining wide distribution for use in the correlation and prediction of vapor-liquid equilibria today. Vapor liquid equilibrium data for 247 binary systems have been regressed against each of ten (10) objective functions and values of the Wilson energy parameters obtained. For the typical binary system, a wide variation of the Wilson energy parameters are observed when different objective functions are used with the given set of binary data. These are each examined with respect to their capability to correlate multicomponent vapor-liquid equilibrium data for seventy-three (73) …

Image Intensification By Superimposed Vesicular Images Generated By Decomposition Of Hydrogen Peroxide, William Grabenstetter

Theses

In the late 1960's, Weyde discovered that treating conventionally processed silver halide films with hydrogen peroxide led to intensified densities by the superimposition of vesicles at the silver image sites. This project attempted to reproduce the results of 5° - 10°DIN speed increase and excellent sharpness mentioned in the patents issued to Weyde. Using the patents as a reference, a paste of urea hydrogen peroxide and PEG was examined as an image intensifier, with no success. Alternate binders suggested in the patents were then examined, Triton X-405 proving to be the best. A paste of 4g. urea hydrogen peroxide in …

Mtf And Adjacency Effects Of Vesicular Film, Timothy Sewell, Paul Willig

Theses

The Modulation Transfer Function and adjacency effects are important measurements of a photographic material. For vesicular film it is of interest to investigate the MTF and adjacency effects with relation to the three variable parameters, development temperature, exposure and development time. This investigation clearly shows that adjacency effects do occur in vesicular film, and that exposure and development temperature are important factors in determinating the film MTF.

Bioenergy And Emotions, Vickie C. Walter

Theses

This thesis explores the concept of bioenergy as an integral force underlying both human physiology and emotional experience. Drawing on a wide range of historical, cultural, and scientific perspectives, the work examines how different traditions and researchers have conceptualized and attempted to measure or influence this subtle energy. The discussion begins with Wilhelm Reich’s notion of “orgone energy,” a vital force he linked to psychological health and emotional regulation. Reich’s controversial theories and experimental devices are considered in the broader context of psychoanalysis and somatic therapy.

The study then traces parallels between Reich’s work and ancient energy systems such as …

The Effect Of Silicic Acid In The Fountain Solution, Kayode Ajibade

Theses

Silicic acid is a water soluble colloidal resin which can be obtained commercially. The effect of silicic acid as a desensitizer in fountain solution was studied. The resin of this colloidal solution was compared to gum arabic solution. The study included the investigation of the physical properties of the solution at different concentrations as well as press performance. Comparisons were drawn regarding wettability, viscosity, surface tension, dot size change, minimum dampening rate to clean-up the non-image areas, resolution, resistance to scum, blinding of image areas, rate of de-inking over- run non-image areas, performance distinction between lithium silicate and sodium silicate, …

Punctuation Frequency In Selected American Daily Newspapers, Andrew Malcolm

Theses

American daily newspapers present millions of punctuated sentences to the public, yet--after an extensive search of literature for similar studies--no comprehensive study of punctuation frequency seems to have been made before this study. It is hypothesized (1) that punctuation appears at predictable rates in the main news section of American daily newspapers, (2) that statistically significant differences exist in punctuation frequency between each of five selected newspapers and--by group--between those of large and small cities, and (3) that statistically significant differences exist in punctuation frequency between 1976, 1966, 1956 and 1946. Five newspapers were selected for the study: The New …

Frederic W. Goudy Correspondence 1935-1946, Anne Thomen

Theses

American printing of the late nineteenth century was crude and commercial in the worst sense. The ideals and vitality that William Morris, Emery Walker, C. H. St. John Hornby, Charles Ricketts, T.J. Cobden-Sanderson and others injected into English printing during the last decades of the nineteenth century and into the twentieth were known to relatively few Americans. One of those few Americans was Frederic W. Goudy, March 8, 1865--May 11, 1947. Paul Johnston in an article for the Fleuron (No. VII, 1930, p. 191A) wrote, "It was the part of Frederic W. Goudy to help the general printer in America …

Correlation Study Between Subjective And Objective Scene Classifications, Craig Campbell

Theses

In addition to the quality of an original (transparency or reflection) preferred halftone reproduction is also dependent on scene classification. That is, how the tones of the original are rendered. If the majority of the picture area contains light tones, it is referred to as a high key image. Should the majority of picture area be confined to dark tones, it is referred to as a low key image. When the picture area is composed of the entire tone scale (white, grays, and black), it is referred to as a normal key image. The problem of how to objectively classify …
