Social, Economic, Environmental, And Technical Factors Influencing Water Reuse, A. Bruce Bishop, Suravuth Pratishthananda, John Keith, Craig Colton, A. Berry Crawford

Reports

A growing population together with rising per capita income has resulted in increased demand for water for virtually all uses. At the same time there has been increased public concern for maintaining the quality of streams for recreation, sight-seeing, and other social uses, and to conserve environmental values. A partial answer to these conflicts in water use and management is more extensive waste water reclamation and reuse. Heretofore, water salvage and reuse has been mainly practiced in specific operational cases, such as recycling industrial process water, or on an ad hoc basis, such as a series of diversions and subsequent …

A Study Of The Splash-Plate Tower Concept, A Biological Wastewater Treatment Process, Robert Joseph Millman

Masters Theses

"Different modifications and newer methods of treatment which utilize the basic trickling filter concepts, such as the Bio-Disc process, have been developed to increase the efficiency of wastewater treatment. The purpose of this investigation was to develop and evaluate a newer such method called the splash plate concept.

The splash-plate concept utilizes a series of circular plates mounted horizontally on a vertical axis. This allows the wastewater being treated to travel over one plate to the edge and splash down to the next lower plate and so on throughout the tower. A total of four units were operated at different …

The Effect Of Porosity On Strength Degradation In Thermally Shocked Alumina, Russell David Smith

Masters Theses

"Strength degradation and crack propagation in Al₂O₃ are shown to depend on the initial strength and porosity of the material. Specimens were fabricated containing between 0 and 5% induced cylindrical, two dimensional, and spherical porosity. The strengths of the various porosity samples decreased discontinuously at a critical quenching temperature. No difference was observed in the critical temperature for the various aluminas; initial strength decrease occurred between 165°C and 175°C temperature differential. The strength retained after thermal shock decreased with increasing initial strength. The degree of damage sustained upon shocking was also characterized by crack density and crack …

The Effect Of Explosive Charge Length Of Cratering, John M. Mason

Masters Theses

"In an attempt to determine the influence of charge length upon cratering, a series of small scale model blasting experiments were conducted in Plexiglas, Hydrostone, mortar and dolomite, using mild detonating fuse as the explosive charge. Single hole blasts were simulated, with the blasthole being drilled normal to one free face and parallel to a second. The resultant craters were photographed and closely studied. Particular attention was paid to effects of variation of charge length and burden upon cratering.

The investigation showed the importance of radial fracturing and the dominance of gas pressure in explosive crater formation from elongated cylindrical …

The low-loss cavity modes are related to ordinary gaussian beam modes. Two limiting forms are the disk laser and the tube laser, and some applications are considered.

Hydrostatic Extrusion Of Waste Glass And Plastic, Subhash Govind Kelkar

Doctoral Dissertations

"Waste glass and waste plastic combine to form a major portion of nonbiodegradable, solid waste. These waste products aggravate the already too serious problem of environmental pollution. Hence, a means is sought of utilizing this waste in the construction industry, thus solving two problems simultaneously - that of beautifying the environment, and of procuring inexpensive building materials.

Extrusion is not an uncommon process as far as the manufacture of original products is concerned. Hydrostatic extrusion is a modification of the process wherein a billet or slug of some material is forced to flow through a die under the influence of …

Electro-Reduction Of Bromate On Mercury, Jaw-Shin Chang

Doctoral Dissertations

"The electrochemical reduction of BrO⁻₃ was studied on a stationary Hg electrode in neutral and basic solutions containing K⁺, Na⁺, and L⁺. Coulombic efficiency studies showed Br⁻ to be the predominant reduction product. The steady state kinetic parameters include Tafel slopes of ca. -0.120 V, approximate first order activity dependences for both BrO⁻₃ and the accompanying cation, and no pH dependence. A reaction scheme is proposed which involves BrO⁻₃ "bridged" to the electrode by the accompanying cation. It is suggested that the "bridging" is a result of ion-pairing in the electrical double-layer"--Abstract, page 1.

Methods For Predicting The Influence Of Intense Sound, Steady Flow, And Elevated Temperature On The Acoustic Performance Of Automotive Exhaust System Components, Richard Chuka Oboka

Doctoral Dissertations

"The principal objective of this investigation was to study the feasibility of developing laboratory techniques for automobile-exhaust muffler design in order to reduce the amount of on-vehicle trial-and-error testing currently required. The investigation included (1) improving the capability of existing laboratory equipment to simulate the conditions in automobile exhaust (i.e., high-amplitude pressure waves, steady flow, and elevated temperature), and (2) theoretical and experimental studies of typical acoustic elements (side-branch resonators, expansion chambers, louvered tubes) used in muffler design. The sound fields used for these studies included pure tones, single pulses (tone bursts), random noise, and simulated automobile exhaust noise.

The Effects Of High Pressure And Temperature Environments On The Properties Of 6061-T651 Aluminum, Patrick George Davidson

Doctoral Dissertations

"During this experimental testing program the effects of the simultaneous application of high pressure and temperature environments on the mechanical properties of 6061-T651 aluminum were analyzed. From the data obtained at the yield and ultimate points a yield and ultimate model was developed based upon the parameters effective stress, effective strain, and the hydrostatic component of stress. This model was obtained solely from the data acquired from uniaxial tensile specimen tested at various pressures and temperatures. Two other loading paths--biaxial tension and torsion--were then used to verify the accuracy of the model. From the testing program, data were also obtained …

The Fate Of Hazardous Polluting Substances In An Aqueous Environment, Robert Paul Casani

Theses

The fate of Hazardous Polluting. Substances (HPS) in an aqueous environment has been investigated using ultraviolet light. Chlorobenzene, o-cresol and nitrobenzene were used as model HPS for this study. The kinetics were followed and good first order plots were obtained for all compounds. The temperature of the reaction was shown to effect the rate. Solid insoluble and soluble non-volatile products were formed in the photolytic reaction of the three model systems.

Skid Resistance Of Pavements [Sept. 1972], Rolands L. Rizenbergs, James L. Burchett, Cass T. Napier

Kentucky Transportation Center Research Report

Standard pavement types and experimental surfaces on roads throughout Kentucky were evaluated in terms of skid resistance and effects of traffic, wear, and polishing. Friction-vs-speed gradients and the relationships between locked-wheel and incipient friction were determined. Asphaltic concrete pavements on high-speed, four-lane roads were found to be significantly more skid resistant than on two-lane highways and somewhat more skid resistant than concrete surfaces (especially those containing calcareous gravel aggregates). Sand-asphalt surfaces containing significant proportions of limestone sands showed inadequate level of friction for the traffic sustained. Several experimental sand asphalts without limestone sands exhibited greater skid resistance; Kentucky rock asphalt …

A Solid State Kinetic Study Of Potassium Permanganate In Alkali Halide Disks, Joseph Paul Cusumano

Theses

The stoichiometry and the kinetics of the reactions of KMnO₄ in KCl and KIO₄ in KCl were studied. The kinetics of the reactions were studied at three different temperatures to obtain the thermodynamic parameters. In addition, these reactions were studied in KBr and RbI matrices. The data was obtained using infrared spectrophotometer measurements.

The reactions all appeared to be first order with respect to the permanganate ion. The stoichiometric studies indicate that the Mn₄^- is converted to Mn⁺⁺ and the Mn⁺⁺ ion apparently catalyzes the reduction of KI₄. The results indicate the …

Analysis Of Decomposition Gases And Leach Water From Controlled Sanitary Landfill, Robert Gargano

Theses

A sanitary landfill was simulated by placing "refuse" between two layers of soil in 6" by 24" cylinders. Canine nutriment was used to simulate the refuse. Once the refuse began to decompose, the decomposition gases were collected in a gas cell and analyzed in an Infrared Spectrophotometer. When gas samples were not taken, the decomposition gases were vented through a water trap (to prevent air from backing up into the system) into the atmosphere. Distilled water was added and withdrawn at two week intervals to leach out the pollutants.

From the Infrared analysis, the decomposition gases were determined to be …

Flow Behavior Of Molten Polymer Blends, Kryspin Pawel Maciejewski

Theses

An experimental study of molten polymer blends was made using the Instron Capillary Rheometer. The materials investigated were two phase blends of non-crystalline polymers (poIymethylmethacrystate-low Mw-polyvinylacetate, polyvinylacetate-polystyrene, polymethylmethacrylate-low Mw-polystyrene, polymethylmethacrylate-high Mw-polystyrene), crystalline polymers (polyethylene-polypropylene) and combinations of non-crystalline-crystalline polymers (polyethylene-polystyrene). Two methods of sample preparation were used, blending of a polymer pair in a molten state by the use of Brabender blender, and a simple manual blending of pellets in desired proportion. The Brabender blended polymer pairs show lower viscosities, this is interpreted molecularly as a result of a reduction of the amount of chain entanglement on shearing of the …

Gain And Dispersion Focusing In A High Gain Laser, Lee W. Casperson, Amon Yariv

Electrical and Computer Engineering Faculty Publications and Presentations

The transverse modes of a laser resonator containing a medium with a strong radial gain profile differ greatly from the modes of a similar resonator containing a low gain medium. Focusing and defocusing effects result from the gain profile and from the associated dispersion profile. The dispersion focusing causes an asymmetry in the power output as the laser is tuned across the gain line. The theory has been verified using a high gain 3.51-µ xenon laser.

Localized Wastewater Treatment Facilities, Robert Russell Garrett

Retrospective Theses and Dissertations

The report describes an alternative to the use of septic tanks for invidual dwellings. The major problems confronting the larger wastewater treatment plants (0.012 to 10 million gallons per day) in central Florida are also discussed. Solutions in this report are for individual and multi-unit dwelling treatment systems (to 0.06 MGD). these units can provide 90% biochemical oxygen demand (BOD) and suspended solids (SS) removal in accord with new state and county regulations. A comparison of the large versus the small plants reveals that small innovative plants, though more expensive, are more environmentally sound than the poorly operated large facilities. …

Automation In Banking, Donald P. Matteson

Retrospective Theses and Dissertations

It has been estimated that the Apollo Program, which placed a man on the moon, each year produced enough paper work, that if put on one stack, would reach to the moon. The forthcoming Space Shuttle Program will require even more documentation; however, present plans call for very little paperwork. The necessary documentation will instead be created, updated and retained in a large computer data base with access throughout the country. Present technology will support this system. The banking industry has been faced with a similar problem in the processing of demand deposit records (checks) and other repetitive tasks. Banks …
