Kinetics Of Rehalogenation Bleaches, Kenneth A. Harrison

Theses

A study was made to determine if a correlation existed between the silver density at 318 nm and the actual amount of silver present in photographic film. Based on twenty (20) samples of bleached and unbleached film, a linear correlation was found, for specific film/ developer combinations, with a correlation coefficient in excess of 0.99. The above correlation was then used to evaluate the bleaching kinetics of several rehalogenation type bleaches. It was postulated that there is a charge barrier effect between the photographic gelatin and the positively charged oxidizing agent in the bleaches. This was caused by the pH …

Treatment Of The Second Degree Athletic Ankle Sprain, Michael P. Pratte

Theses

The ankle injury is one of the most common athletic injuries. Proper treatment of the sprained ankle can avoid more serious complications and in sure early return of the athlete to activity. There exists a wide variety of medical opinion concerning treatment of the second degree ankle sprain. This divergence of medical opinion creates confusion on the part of the athlete, coach, and parent. This project has attempted to give coaches, physical education teachers , and parents a better understanding of the types of treatment available, where these therapies may be found, and which treatment may be most effective.

The Effect Of Emulsion Stabilizers On The Rate Of Solution Of Silver Halide Grains, Christopher L. Dumont

Theses

The effects of the emulsion stabilizers, 4-hydroxy- 6-methyl-l ,33a,7-tetraazaindene and l-phenyl-2-tetrazoline- 5-thione on the rate of solution-physical development of a monodisperse AgBr emulsion containing Carey-Lea silver sol were measured at a series of concentrations. A study of the effects of the silver halide solvent, sulfite has been stud ied along with a low-solvent surface developer. It was found that the tetraazaindene definitely had an effect on the rate of solution-physical development, while the l-phenyl-2- tetrazoline- 5-thione did not have a significant effect.

The Determination Of Using The Standard Screening Angles When Printing With 400-Count Anilox Rolls And 100 Line Images Via Flexography, John Ahrens

Theses

From the pioneering efforts of the early 1960 's, flexography has shown steady progress in the development of four color process printing. However, the ability to consistently produce it is limited to an elite group. The vast majority of companies have yet to competitively enter this demanding area of printing. For these companies the time, expense, and expertise required to conduct an indepth study is a major deterrent. Outside information must be made available to aid the companies. The FTA and its members have greatly contributed by publishing an array of information; although, some basic questions have yet to be …

Influence Of First Developer Solvent Levels On The Information Storage Capacity Of Negative And Reversal Images, Wendy R. Harrison

Theses

Silver halide solvents are commonly used in the first developer of a reversal process to obtain brighter highlights and a higher effective speed. An investigation was carried out to determine the effect of a low and high level of solvent on the sensitometric char acteristics as well as the covering power, granularity, modulation transfer function (MTF) and the information storage capacity of Plus-X reversal film 7276. The investigation was designed such that the only variable in the systems studied was the first developer. D-67, i.e., D-19 containing two grams liter^-1 of potassium thiocyanate, was chosen as the high solvent first …

Impingement Of An Axi-Symmetric Jet On A Flat Surface, Amir J. Daibes

Theses

An incompressible, inviscid irrotational flow model was used to represent the normal impingement of a circular axisymmetric jet upon a flat plate. An analytical investigation was conducted to determine the free surface of the jet and the solution of the potential flow problem was obtained using finite difference techniques for jet height-to-nozzle radius ratio of 2.4.

The velocity and pressure distributions at the plate surface and along the jet centerline were obtained.

The results from the finite difference solution are in close agreement with other most recent results from available experimental, and approximate solutions to the potential flow problem.

A Microprocessor Based Digital Logic Simulator, Kevin Dresher

It is the intent of this thesis to acquaint the reader with a tool which is available for use in the digital circuit design field. The reader is now able to totally simulate via DLS the digital logic design he creates on paper before it ever takes a hardware form. The computer program accepts a detailed description of the schematic and creates timing diagrams, loading statistics, cross references, and various lists for future documentation.

The user needs no programming knowledge and will find the requirements to run a simulation with DLS extremely user oriented. The simulation descriptions and command language …

An Experimental Study Of Photopolymerization In A Continuous Stirred Tank Reactor, Songvit Setthachayanon

Theses

An experimental study was carried out on the control of CSTR by on-off regulation of light intensity for the photo-sensitized polymerization of styrene. The controllability of the reaction temperature, the advantages of operating at metastable states, and the molecular weights of the polymer formed were discussed. The influence of feed temperatures, sensitizer concentrations, and residence times on the reactor performance characteristics were also discussed. Experimental results showed that polymer formed at the metastable state had a higher average chain length and narrower molecular weight distribution than that formed at the low stable state. While increasing the residence time shifted the …

The Effects Of Concurrent Photon Amplification Utilizing An Infrared Latensification Source, Mitchell D. Feather

Theses

An investigation was conducted regarding the effects of varying supplementary exposure on High eSpeed Infrared Film. In addition, CPA was evaluated in comparison to Hypersensitization and Latensification. The results were that CPA is superadditive with respect to both density and exposure, the maximum effect being noted in the toe of the characteristic curve. Furthermore, Hypersensitization and Latensification , with dark intervals up to five seconds, displayed efficiency that was not significantly different from CPA. It was also determined that the spectral distribution of the imaging source does not affect the efficiency of CPA. Corroboration of C&C Research's speed increase claims …

Plate Stability In Screenless Printing, Stephen E. Martin

Theses

Lithography in the minds of most people is a method of reproducing a photograph or artwork by means of a halftone screen. The screen, usually no finer than 400 lines per inch reproduces the image by varying degrees of density through control of the dot size. With screenless printing the image is reproduced without the screen, resulting in much better detail. The purpose of this thesis is to determine what type of plate material will work best with the "Association Product Coating", since the ST Sumner Williams plate that worked well with this coating is no longer produced. The criterion …

Structural Aesthetics In Furniture Design, James Clark

Theses

The purpose of my thesis will be to incorporate structural members as aesthetic elements in furniture design. In architecture, structure is a major design concern. As a result of the interrelationship between these disciplines, I will apply architectural principles to furniture design. In my thesis I propose to expose and use structure for defining form. More specifically I plan to utilize structure in ways that reveal its own beauty through its functional purpose. I plan to explore this idea by producing as many pieces as possible during the year of my thesis work. Each piece done will involve techniques and …

The Use Of The Calculator In The Junior High Mathematics Curriculum, Janice Warner

Theses

This study explores the impact of handheld calculator use on student achievement in middle school mathematics, with a focus on seventh-grade instruction in decimal algorithms. Conducted at Wentzville Junior High School, the research involved a three-week instructional unit on decimals taught to two groups of seventh-grade students—one using calculators and the other employing traditional paper-and-pencil methods. Pretests and posttests were administered to measure student performance, while classroom observations and teacher feedback were used to assess engagement and problem-solving strategies.

The findings indicate that the use of calculators improved student accuracy and efficiency in computation without diminishing conceptual understanding. Students with …

Spatial Filtering Of A Projection Printer, Using Partially Coherent Light, Leon Vlahakes

Theses

This investigation applied the technique of spatial filtering to a projection printer utilizing partially coherent illumination. The affect of filtering on image quality parameters such as resolution, edge gradient and MTF were determined for a black and white film. Edge gradient analysis was used to derive MTF data from sampled edges. A source diameter of 3 mm and spatial filter diameters of .6, 2.2, and 3.0 mm were used. Spatial filtering was seen to have a drastic affect on edge gradient and MTF. Increasing the filter diameter resulted in a decrease of cutoff frequency of the system. Spatial filtering had …

Halftone Dot Method For Image Evaluation Of High-Resolution Films Applied To Vesicular Film, Mark Gulden

Theses

A feasible technique for deriving the spread function and modulation transfer function of a vesicular film has been determined. This technique is based on a method described by R. Byer which does not require the use of a microdensitometer, but only that of a "macro" densitometer. The method utilizes the fact that a halftone dot will change in size as a function of exposure. The spread function of the vesicular film was approximated with a mathematical model. The results, although favorable in many ways, are not conclusive. Some of the advantages and disadvantages associated with this technique as applied to …

A Study On The Improvement Of Rop Newspaper Color Through Modification Of The Reproductive Curve To Lighten The Overall Reproduction, Ronald Assoian

Theses

Most run on paper offset newspapers have not shown the capability of producing color reproductions without having the prints subject to a darkening or a muddy look. This problem is basically caused by the absorbency of the newsprint. Since the newsprint is so absorbent, the ink can only be printed to a low solid ink density and coarse screens must be used so the dots do not fill-in. To eliminate this problem, it is believed that if the midtones are reduced on the gray scale during the separation process, and then the wanted colors' dot areas are restored to their …
