The Use Of Thermal Analysis In The Identification And Characterization Of Fibers Of Forensic Interest, Ronald J. Coffey

All-Inclusive List of Electronic Theses and Dissertations

This study investigates the use of thermal analysis for the identification and characterization of fibers for forensic purposes. Fibers such as polyesters, polyacrylics, polypropylenes and nylon were investigated by Differential Thermal Analysis (D.T.A.) and Thermogravimetric Analysis (T.G.A.) to see if their resulting thermograms were characteristic of each fiber. Also, infrared analysis was performed on each fiber. In addition, such factors as heating rate and sample size along with fiber blends were studied as to their effect on thermograms. As a result of this study several important conclusions may be drawn. Although it was found that for the most part D.T.A. …

Plasma Polymerization Of Tetrafluoroethylene. Iii. Capacitive Audio Frequency (10 Khz) And Ac Discharge, N. (Nicholas) C. Morosoff, H. Yasuda, E. S. Brandt, C. N. Reilley

Chemical and Biochemical Engineering Faculty Research & Creative Works

The plasma polymerization of tetrafluoroethylene (TFE) is studied in a capacitively coupled system with internal electrodes using a 10 kHz (af) and a 60 Hz (ac) source. The emphasis is on identifying conditions that are compatible with continuous coating of plasma polymer on a substrate moving through the center of the interelectrode gap. Operation at a pressure below 100 mTorr is most favorable for deposition of a substantial portion of the plasma polymer on this substrate. Plasma polymer deposited in this way is characterized by ESCA and by deposition rate data and compared to that deposited using rf power in …

Plasma Polymerization Of Tetrafluoroethylene. Ii. Capacitive Radio Frequency Discharge, N. (Nicholas) C. Morosoff, H. Yasuda, E. S. Brandt, C. N. Reilley

Chemical and Biochemical Engineering Faculty Research & Creative Works

The plasma polymerization of tetrafluoroethylene (TFE) is studied in a capacitively coupled system with internal electrodes using radio frequency (13.56 MHz) power. The emphasis is on identifying conditions that are compatible with continuous coating of plasma polymer on a substrate moving through the center of the interelectrode gap. At high pressure (500 mTorr), deposition of plasma polymer is primarily on the electrodes rather than on a substrate placed midway between electrodes. Glow is observed in only part of the interelectrode gap at low powers and fills the gap only at high power levels. The use of a magnetic field effects …

Plasma Polymerization Of Tetrafluoroethylene. I. Inductive Radio Frequency Discharge, H. Yasuda, N. Morosoff, E. S. Brandt, C. N. Reilley

Chemistry Faculty Research & Creative Works

The plasma polymerization of tetrafluoroethylene in an inductively coupled radio frequency glow discharge, using a flow system, was studied. A simple long tube reactor, with the coupling coil placed at the middle of the tube and gas entrance and exit at the respective ends, was used. Deposition rates and the chemical nature of the polymer (as revealed by ESCA spectra and surface energy studies) are obtained as a function of location in the reactor tube with respect to the coupling coil and of applied energy per unit mass of tetrafluoroethylene (W/FM). It was found that a fluorine poor polymer, containing …

Low Btu Producer Gas -- A Fuel Of The Past And A Fuel Of The Future, Lee Carter

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A prime purpose of this paper is to give conscious emphasis to an important type of coal gasification, one that does not demand hundreds of millions of dollars to launch an experimental program but instead is essentially ready to use after a reasonable and straightforward engineering check-out of the local coal sources and the prospective gas demand.

That type of coal gasification results in low Btu producer gas. This paper deals with its history, its technology and its economics. In the light of that information, the future of low Btu producer gas in America then is assessed.

Effective Utilization Of Energy From Biomass Residues In Agricultural Applications, Harry W. Parker

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Biomass is one of the more attractive alternative energy sources. Use of existing biomass residues within the farm and ranch economy can be accomplished with a minimum of organizational problems since the producer, processor, and consumer may be the same person or organization. The major task is to provide potential agricultural biomass users with accurate cost estimates for the energy made available from the biomass, and contemporary technology for its utilization.

Specific examples are given with regard to powering irrigation well engines with cotton gin trash via a producer gas generator, and conversion of harvested mesquite wood to digestible energy …

Comparison Of Stirred And Immobilized Cell Reactors For Ethanol Production, Oliver C. Sitton, J. L. Gaddy

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Biomass can be converted to sugars by hydrolysis with enzymes or mineral acids. These sugars can be converted into a number of chemical intermediates in biological reactors. Biological reactions are generally slow and selection of the most efficient reactor is important in these applications.

Immobilized cell reactors allow high cell densities and high throughput by attaching microorganisms to a fixed support. This paper compares the rate of production of ethanol from glucose by Saccharomyces Cerevisiae in a packed column and a stirred reactor.

Continuous stirred reactor studies showed a washout rate of .27 hr^-1. The optimum rate of …

Burning Wood As A Supplement To Solid Waste, Andrew R. Banta, William P. Smith

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The University of Kansas at Lawrence uses natural gas and oil to generate steam for heating and other campus needs. The projected price increase of these fuels has led to a study of burning solid waste and wood. This study discusses the technical and economic considerations of burning wood. Topics included are sources and availability, collection and transportation, preparation and burning, and environmental effects. It is concluded that sufficient wood is available; truck transport is the only feasible option; drying some wood is desirable; and that the burning can be done separately or directly with the solid waste.

Geophysical Approaches To Coal Exploration, Gerald B. Rupert

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The exploration for minerals by geophysical means has been confined largely to the search for hydrocarbons and metallics while applications to coal exploration are somewhat limited. However, the surface reflection seismic technique has been successfully applied not only to delineating coal deposits but also as a tool in mine exploitation. Furthermore, channel waves generated underground have demonstrated potential in detecting the presence of faults in advance of the coal face and Vibroisis* experiments have been conducted whereby abandoned underground workings have been detected by surface seismic arrays. Examples of all of the preceeding are presented and discussed.

Energy - Minerals - Environment: How Now Brown Cow?, Bobby G. Wixson

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Energy, technical, social, political, economic, and environmental problems are all people related problems which will continue to increase along with the world's population. With the growing demands for more energy and minerals along with the constraints of protecting the environment, new approaches must be considered to these complex problems.

Energy sources, modifications, alternatives, and new developments must be considered for the present as short term resources (next 25- 30 years) and in the future as long range research necessary to develop and implement new technology (25 years on). Major energy sources and their environmental considerations are generally classified as:

The Synthesis Of New Maleimide Addition Polymer Precursors, Richard B. Brown

Chemistry & Biochemistry Theses & Dissertations

1H-2,3-dimethylpyrrolo(1,2-a) benzimidazol-l-one (27) and 1H,9H- 2,3,7,8-tetramethyl-bispyrrolo(1,2-a:6,7-a')benzodiimidazo1-1,9-dione (32) have been synthesized from dimethylmaleic anhydride and o-phenylenediamine and 1,2,4,5-tetraaminobenzene, respectively. The presence of reactive olefinic double bonds in the synthesized compounds was of interest as a site for possible addition polymerization.

The synthetic route involved, in both cases, a simple nucleophilic substitution reaction between the diamine(or tetraamine) and the anhydride to form an intermediate amide-acid-amine which rapidly cyclized to the imide amine. The final ring closure required more rigorous conditions and occurred at melt reaction temperatures.

Process Control Of Activated Sludge Treatment, Phase Ii, Richard I. Kermode, Robert W. J. Brett, Joseph D. Pault Jr.

KWRRI Research Reports

Material balances on substrate and microorganisms were derived in conjunction with various mixing configurations thought to accurately describe the activated sludge process. These models include the completely mixed with bypass, plug flow, and plug flow with bypass. Two sets of kinetic mechanisms for substrate utilization and bacterial growth were employed.

A feed forward controller was designed from linear approximations of the material balances derived in the completely mixed with bypass mixing model. Utilizing frequency response methods, the controller was found essentially identical to a completely mixed modeled controller developed in a prior investigation.

Through computer simulation the controller's effectiveness was …

The U. S. Wind Power Program, Joseph M. Savino

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Today I would like to talk about wind energy in, basically, two parts. I would like to bring to your attention some of the developments that have occurred in the 20th century. Many of us who have gone through school in the last 25-30 years don't recall anywhere in our engineering education much information dealing with wind energy, and that may come as a surprise to you as it did to me, to learn how much has actually been done in the 20th century to develop large scale wind-driven machines. After I get through with that introduction I would like …

The Energy Problem -- Crude Oil, J. A. Marshall

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This paper discusses the national energy problem as it affects the demand for and availability of crude oil. Forecasts of energy demands to 1990 have been made based on population trends and changing life styles in the USA. Projections of energy supplies show a rapidly increasing gap between supply of crude oil and demand for crude oil from the early 1970's through 1990. The need for imported crude oil to supply the forecast deficit is discussed. The political and economic implications of these imports are also discussed. The need for refineries, port facilities, tankers, and pipelines are presented. Finally, recommendations …

Coal Gasification And Liquefaction, Sam Friedman

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The current major processes being developed for coal gasification and liquefaction will be reviewed briefly. The Bureau of Mines Hydrane process for converting coal to pipeline quality gas directly by reaction with hydrogen will be discussed in more detail. The featured topic will be the Bureau's Synthoil process which converts coal in one step into a low-sulfur, low-ash fuel oil. Coal suspended in recycled oil is propelled through a packed-bed reactor by rapid turbulent flow of hydrogen. A 1/2 TPD plant is in operation producing over 1 bbl of oil per day.

Coal And Its Derivatives As An Energy Resource, W. G. Stockton

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

April 25, 1974

Events of the last few months, it seems, have somewhat altered the public countenance of the coal industry. These events, I am sure, are the generating factors focusing interest on our industry currently, and I suspect they account for my invitation to address this distinguished group of engineering students today on the subject of coal in this nation's energy outlook.

Coal Mining is not a new industry - - it has been around a long, long time. A surprising number of people, though, have never seen any coal; they are not aware of the existence of the …

Status And Outlook For Energy Conversion Via Fuel Cells, John P. Ackerman

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Fuel cells have the potential of providing good solutions to a variety of energy-related problems. As our supplies of conventional fossil fuels are depleted, their cost will rise, and there will be increasing difficulty in obtaining certain premium fuels at any price. It behooves us, then, to use our remaining reserves of fuels as efficiently as possible. Energy conversion via fuel cells represents one of the best ways to achieve this goal, because it is possible, simultaneously, to obtain more work and less pollution from a dollar's worth of fuel with a fuel cell than with any other device.

An Overview Of Natural Gas Supply And Availability, D. E. Gibbs

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Natural gas presently supplies almost one-third of the total U.S. energy supply--and like oil, has had its proven reserves reduced by ever-increasing production. The potential gas reserves of the United States are sufficient to maintain our present demand for a considerable period of time, if these reserves can be found. The exploration necessary has to be financed by increased gas cost. Additional technology will be necessary to increase the amounts of gas that can be produced from our present and future supplies. Several methods of obtaining the capital necessary to perform the additional drilling and areas of technical improvement are …

Bellamy Field Tests: Recovery Of Medium Gravity Crude Oil From Missouri Tar Sands By Counterflow Underground Burning, J. C. Trantham

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

In the current energy shortage, the heavy oil and tar sands of the United States are assuming critical importance. This is true for at least two reasons: first, they constitute a major resource, amounting to some 150 billion barrels in place; and second, their where-abouts is known -- exploration will not contribute to the lead time required for bringing these resources into the national energy picture. Moreover, many of the technological problems have been solved. The delay in producing these heavy oil and tar deposits is due primarily to economics.

A Proposed Coal Slurry Pipe Line, R. W. Toler

Clean Fuel From Coal For Electric Power Generation, J. Agosta

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Several strategies have been studied and applied for the reduction of sulfur-dioxide emissions from power generation sites. These include switching to low sulfur fuels, stack gas processing, and a greater reliance upon nuclear power. One area of interest is the processing of fuel prior to combustion through the total gasification of coal to produce a fuel gas suitable for combustion in utility boilers and gas turbines. Specifically, this paper will deal with need for coal as a fuel in the generation of electric power, the production from coal of a clean power fuel gas of-approximately 150 to 200 Btu and …

Power Transmission Technology For The 1980-1990 Time Period, T. H. Lee

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

It is a great pleasure for me to have this opportunity to present to you a subject that is very close to my heart - future transmission systems. Electrical demand in the U.S. is doubling every ten years. While the electric growth capacity characteristics are being questioned for the future, the best estimates are that this will continue at least through the 1990’s.

Load tends to be concentrated in cities and historically generating plants were located in cities. Environmental considerations for fossil plants are tending to locate them away from cities and the trend is expected to continue. Reluctance to …

Solar-Thermal Energy Conversion, E. R. G. Eckert

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The fact that our conventional fuel resources are finite and will be exhausted some time in the future gives impetus to a consideration of solar radiation for conversion into heat or electric power. The characteristics of the solar radiation - that the enrgy flux density is small and that it arrives intermittently on the ground of our glove has to be considered in any system utilizing this energy source. For home heating parts of the roof offer a sufficiently large area, for electric power production areas of some km² are required to collect a sufficient amount of energy. Optical …
