Theses

DTIC and BCNU have been demonstrated to have enhanced chemotherapeutic effects in mice bearing Bl6 mouse melanoma cells. The order of administration seems to be important in maintaining optimum effects. This was shown is a study by Hill et al. (unpublished).

In the present study, mouse melanoma cells, Bl6CL4, were treated with either DTIC or BCNU. The drug was allowed to remain on the cells for 2, 3, or 4 days. The drug-containing media were then removed, the cells were washed and fresh medium was added. The cells were incubated in an atmosphere of 5% CO2 and 95% air at …

Vapor Pressures Of Some Coal Oil Fractions, David G. Gaydos

Theses

New data on coal tar oils and data from the literature on pure compounds and oils derived from coal were used for testing the predictions by the correlation of Maxwell—Bonnell. Based on the observation that the discrepancies between the predicted values and the data are systematic, recommendations were deduced on needed modifications to the correlation. A proposal for modification to the Maxwell and Bonnell correlation to improve prediction of vapor pressures of highly aromatic fuel fractions with characterization factors of8 UOPK 10.5 was made.

Experimental data were taken on vapor pressures of fractions of coke oven coal tar oils and …

A Study Of The Human Resources Principles Applied To Telemarketing Programs, Marian Elizabeth Jones

Theses

The objective was to study organizations which have established telemarketing programs to understand the impact of distinct human resources principles used to establish and maintain the sales unit. A questionnaire was developed to determine whether telemarketing programs, which are specifically designed to recruit, select and train inside sales forces, differ from the programs used to do the same with outside sales forces. Furthermore, the sample population was asked whether telemarketing programs contribute to the overall success of the telemarketing force by catering to the special needs of inside sales people. This questionnaire was sent to a sampling of companies who …

The Effects On Hue Resulting From Black Overprinting In Halftone Reproductions, Brian Philippsen

Theses

A type of black printer that only existed in theory is now being applied in the printing industry. The process which makes use of this black printer is known as gray-component replacement. Developed from the extension of the undercolor removal process, the use of gray-component replacement in printing halftone reproductions is said to result in numerous technical and cost benefits. When used to the maximum, the process eliminates one of the three process color inks in a given unit area and prints black ink from highlight to shadow. A problem can result from the use of this process as it …

A Study Of The Effect Of Ink Viscosity On Dot Gain In Offset Lithography, David Dailey

Theses

Dot gain is the enlargement which takes place in a dot from the time the dot is captured or generated on the film until it is printed. Dot gain can cause many problems, including color variation and loss of contrast, and if uncontrolled is one of the main contributors to waste in offset lithography. Of the many factors influencing dot gain, inks have been found to be a major contributor. One property recommended for further investigation is ink viscosity, which is the resistance to flow of an ink. The purpose of this study was to investigate the effect of ink …

A Performance Comparison Of Oversewn, Pva Double Fanned, And Cleat-Laced Bindings, Caroline Frazer Watson

Theses

Librarians and library binders are no longer always able to specify the traditional, superior oversewing method for binding library books. This problem emerged due to economic pressures within several related industries resulting in a proliferation of economic, but often inferior, binding technologies. As libraries are only approximately ten to fifteen percent of total publishers' sales, books cannot specifically be made for the library market. In addition, many of the new binding technologies yield books with insufficient inner margin space to prebind or rebind books utilizing the oversewing binding method. And finally, librarians, also faced with tight budgets, must find economic …

Synthesis And Characterization Of Poly(Amide-Sulfonamides): New Candidates For Reverse Osmosis Membranes., Thevarak Rochanapruk

Theses

Commercially available aromatic diamines such as 4,4'-diamino diphenyl ether and 4,4'-diamino diphenyl methylene were treated with N-acetylsulf anilyl chloride to give the amino-sulf onamido-acetanilide derivatives. These derivatives were treated with 6 M hydrochloric acid to give the diamine monomers containing a preformed sulfonamide linkage. These monomers were polymerized with various diacid chlorides using a low temperature solution technique. Polymerizations using the Yamazaki reaction have also been investigated. The polymers obtained were characterized using infrared spectroscopy, thermal gravimetric analysis and differential scanning calorimetry.

The Effects Of Common Solvents On Different Types Of Flexographic Printing Plates, Jack Jenkins

Theses

A dynamic development which has sparked flexography is the introduction and use of photopolymer plates. These plates have simplified flexographic printing by reducing the amount of time and effort needed to prepare plates for press and makeready. An experiment was conducted to determine the effect of commonly used solvent mixtures on flexographic plates. The plates tested include those using natural rubber, Buna N, and various photopolymers. The experiment specifically studied change in hardness of these plate materials due to immersion in different solvent mixtures over time. Noticeable differances in the degree of softening of plates was observed after 24 hours …

Model Automatic Focusing System For Linewidth Measuring Instruments, John Ingraham

Theses

This paper discusses research on an automatic focusing system for IC-linewidth measuring instruments. The instrument incorporates a collimated light source, a device to move a sample in small, precise increments, and a charge-coupled device. The autofocusing model would measure the step-height of a dielectric sample and correlate the height to a focus position. Thickness of samples on an enlarged scale were measured to verify the feasibility of this device.

Optimization Of An Elastic Drive Belt System Using An Algorithm Of Automated Optimal Design, Gerald T. Lioy

Theses

In this design project an elastic drive belt system is optimized using an algorithm of automated optional design, AOD. First, some basic background information on AOD and elastic drive belt systems is reviewed. An elastic drive belt system configuration is defined, mathematically formulated, and optimized. The mathematical formulation, including a set of constraints, is completely derived. It is set up to be as general as possible so that it may be applied to a wide variety of different problems. In several places the formulation uses the recommendations of an elastic drive belt manufacturer for a good design. A sample design …

An Analysis Of Stroke Fluid Flow In A Converging Channel Using A Penalty Function Finite Element Formulation, Keith A. Honkala

Theses

A penalty function finite element program is developed to study two dimensional creeping flow in a converging channel. The finite element solution is compared to the analytical solution of purely radial flow. The analysis reveals that the assumption of purely radial flow is valid for small apex angles, but is inappropriate for larger angles .

A Comparative Analysis Of Dna Molecular Crosslinking By Dichloro-N-Substituted Azaadamantane Isomers, Harry Robbins

Theses

A series of anti, anti-dichloro-N-substituted azaadamantanes have been synthesized (Henkel et al, 1981, J. Org. Chem. , 46, 3483) representing conformationally rigid nitrogen mustards incorporated into an adamantyl framework with well defined stereochemistry and fixed separation distances between alkylating centers of 3.6 A (1) and 2.5 X (2,3) (Henkel et al, 1981, J. Org. Chem., 46, 3483) to be used as structurally rigid probes of DNA alkylation and intermolecular crosslink formation leading to cytotoxicity. The aqueous solution stability and the extent of intermolecular DNA crosslink formation for both the N-methyl and N-piperdinoethyl series of isomers have been measured using novel …
