Solid Waste Resource Recovery Alternatives, U.S. Facility, Subic Bay, Philippines, Samuel A. Vigil, R. M. Roberts, Donald E. Brunner

Civil and Environmental Engineering

The U.S. Navy Public Works Center, Subic Bay, Republic of the Philippines (PWC Subic Bay) is responsible for the collection and disposal of almost 300,000 yd³ of solid waste annually. A portion of this solid waste is manually sorted and recycled, resulting in gross revenues of over $200,000 in FY82. The present manual sorting and recycling system is considered by PWC Subic Bay to be inadequate in terms of sanitation, safety, and recyclable materials recovery. Therefore , PWC Subic Bay requested that the Naval Civil Engineering Laboratory (NCEL) study the system and recommend improvements.

Keeping Up With Technological Change, Karlis V. Kopans

Theses

Advances in technology over the past fifty (50) years have changed virtually everything that touches our lives today to some degree. However, in the last five years or so, these innovations have been combined into products and systems which have visibly begun to change society as we have known it in the past.

Only in recent years, have the affects of technological change or innovation on society begun to be examined. While a fair amount of literature has been published to date on specific areas of technological change, few publications have been produced which provide a general overview of the …

Biofilm Growths With Sucrose As Substrate, Ju-Chang Huang, Shoou Yuh Chang, Yow Chyun Liu, Zhanpeng Jiang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study was conducted to: (1) Evaluate the effect of DO on cell yield in a fixed film reactor using 1,000 mg/L sucrose as a substrate; (2) evaluate the correlations of the biofilm thickness and density with DO and their resultant substrate stabilization rates; and (3) examine the response of biofilm communities as a result of DO and biofilm thickness changes. Data obtained from this study indicate that DO has only a minor effect on the cell yield. However, the thickness of aerobic biofilm is definitely related to DO, or thickness (mm) = (2.08 x DO)/(9.2 + DO). The biofilm …

Interfacing A Quadriplegic To A Computer Using The Electro-Ocumeter, Paul J. Godfrey

Retrospective Theses and Dissertations

The purpose of this is to design an electro-oculometer system that paper will enable quadriplegics and other persons with severe physical disablities to use a computer. An electro-oculometer is a device that measures the position of a person's eyes. The vertical and horizontal movements of the eyes can be used to control an object on a computer screen. This, in turn, allows the user to operate a computer by eye motion alone. The requirements of the electro-oculometer system are specified and then a block diagram of the system is developed. Each block is then designed and component values are given. …

Metal Leaching Characteristics Of Three Synthetically Generated Metal Finishing Sludges, Christopher M. Cherniak

Retrospective Theses and Dissertations

A study was performed involving the leaching characteristics of three synthetically-generated metal finishing sludges. Three precipitates (one hydroxide, two sulfide-based) containing varying concentrations of cadmium, copper, lead, nickel and zinc were dewatered and subjected to an EPA-regulated limits. The sludge generated from an insoluble sulfide process exhibited the fewest parameters in violation (two), while the soluble sulfide sludge had one metal in compliance and the hydroxide sludge had none. On a metal-by-metal basis, the lead and copper exhibited the greatest capacity to withstand resolubilization in a low pH (5) environment. Nickel and zinc were present at the highest leachate concentrations …

The Quantity Of Stormwater Entering The Drainage Wells Of Orlando, Florida, James M. Mcbee

Retrospective Theses and Dissertations

An extensive literature survey revealed there have been no in-depth studies of the quantity of water entering Orlando area drainage wells. Previous values ranging from 30 to 85 MGD were based on water supply withdrawal information or gross drainage area estimates. This paper presents a detailed study of the quantity of water entering 208 drainage wells in the Orlando Ubran Stormwater Management Manual (OUSWMM) area. Extrapolation of results to the remaining wells in Orange County is discussed briefly. Field experiments on one 20 in drainage well yielded a mathematical relationship that was reasonable for estimating acceptance rates for drainage wells …

Plasma Polymerization Investigated By The Substrate Temperature Dependence., H. Yasuda, Cheng Wang

Chemistry Faculty Research & Creative Works

In the reported experiments, plasma polymerization of tetrafluoroethylene (TFE), perfluoro-2-butyl-tetrahydrofuran (PFBTHF), ethylene, and styrene were investigated in various combinations of monomer flow rates and discharge wattages for the substrate temperature range of minus 50 to 80 degree C. The polymer deposition rates can be generally expressed by k//o equals Ae** minus **b**t, where k//o is the specific deposition rate given by k//o equals (deposition rate)/(mass flow rate of monomer), A is the preexponential factor representing the extrapolated value of k//o at zero absolute temperature, and b is the temperature-dependence coefficient. It was found that the value of b is not …

A Study Of Trihalomethane Precursors In Deer Creek Reservoir, Megan J. White, V. Dean Adams

Reports

Deer Creek Reservoir and tributaries were monitored from May to December 1983 in a study of the occurrence of trihalomethane (THM) precursors in the reservoir and nutrient dynamics of the reservoir system. Microcosms were used to study the effect of the following parameters on THM precursor production in the reservoir system: phosphorus loading, sediment, algal growth, and application of algicide. Additionally, THM precursor concentrations of interstitial water were analyzed in reservoir and microcosm sediment samples. Microcosms treated with ahigh phosphorus loading (70 ug/1) had THM precursor concentrations significantly higher than those measured in microcosms treated with a low phosphorus loading …

Development Of Design Criteria For Sensitizer Photooxidation Treatment Systems, Richard J. Watts, V. Dean Adams, E. Joe Middlebrooks

Reports

Sensitized photooxidation is a physicochemical process that can degrade many toxic and refractory organic pollutants. A trace quantity of sensitizer added to the waste absorbs visible light; electronically excited intermediates then transfer the energy to decompose the waste. Engeineering design criteria were developed for industrial waste treatment lagoons that would use sensitized photooxidation. Design criteria were developed regarding optimum lagoon pH, optimum sensitizer concentration, depth and sizing of lagoons, dissolved oxygen requirements, and effect of temperature on photooxidation rate. Treatment of the refractory pesticides bromacil, terbacil, and fluometuron was investigated using methylene blue and riboflavin as sensitizers. Methylene blue-sensitized photooxidation …

Preliminary Identification, Analysis, And Classification Of Odor-Causing Mechanisms Influenced By Decreasing Salinity Of The Great Salt Lake, C. Earl Israelsen, Darwin L. Sorensen, Alberta J. Seierstad, Charlotte Brennard

Reports

Introduction: The rising level of the Great Salt Lake has received a great deal of attention because of the resulting physical damage to adjoining properties, threatened distruption of major transportation facilities, and environmental damage to feeding and resting areas for migratory waterfowl. Another problem of growing concern is that some zones of the lake are producing odors that are objectionable to nearby populated areas. These odors are most offensive during the warm summer months and appear to be increasing with the rising levels and decreasing salinity of the lake water. This report presents the approach taken and the findings of …

Problems Of Small Privately Operated Water Companies In Utah, Jay M. Bagley, Frank W. Haws

Reports

Although one in seven domestic water supply systems in Utah are privately owned and operated, they are characteristically small with 94 percent serving populations of less than 1,000. Per capita costs of service vary greatly but become relatively high for locations that are remote, where terrain and climate are extreme, where scale economies are absent, and where materials and skills for system repair and replacement are not locally available. Statistics indicate that the incidence of water quality violations relate strongly to system size. Yet corrections are often more difficult to achieve because well trained and full time operators cannot be …

Evaluation Of Percolation Ponds For Design And Operation, David A. Baar

Retrospective Theses and Dissertations

Land application of domestic wastewater effluent by rapid rate infiltration (i.e., percolation ponds) is a very successful and cost-effective method for wastewater management. Municipal percolation pond systems have been successfully operated in the United States for about 100 years. The disposal concept depends on a relatively high rate of secondary wastewater effluent infiltration into the soil by rapid percolation, either vertically or horizontally, away from the application surface area. This study was accomplished to determine infiltration rates at two working percolation pond systems and the variability of these rates, to compare the operating results with the initial design, and to …

Assessment Of Control Alternatives For The Great Salt Lake, L. Douglas James, David S. Bowles

Reports

Introduction: Over the last few years, the rising level of the Great Salt Lake has changed Utah. It has inundated vast waterfowl feeding areas, crippled the salt industry, required raising transcontinental freeways and railroads, threatened metropolitan waste treatment plants, caused a major electrical outage, and damaged many properties. If nothing is done, approximately $3.6 billion of damages in 1985 dollars can be expected by 2050 (James et al, 1985, p.4). This threat led the State Legislature to set aside $100 million (an amount approximating the damages that had then occurred) in January 1985 to identify, select, and implement remedial measures. …

Writing A Scientific Paper Prior To The Research, Charles F. Babbs, Martha M. Tacker

Weldon School of Biomedical Engineering Faculty Publications

The traditional approach to preparing a research report for publication is to begin writing after the study has been completed. We propose another approach- to write a "zeroth" draft before the study is begun. This approach helps to focus the investigator's attention during the planning stage on critical aspects of the study. The discipline of writing down the rationale, the methods, and the variety of possible outcomes and their significance helps to clarify the logic on which the study is based. If these are acceptable to all authors and colleagues in the zeroth draft, it is likely that the research …

Use Of Combined Systemic Hypothermia And Local Heat Treatment To Enhance Temperature Differences Between Tumor And Normal Tissues, Charles F. Babbs, William D. Voorhees Iii, Robert R. Clark, David P. Dewitt

Weldon School of Biomedical Engineering Faculty Publications

The feasibility of combining local heat treatment with wholebody hypothermia in an effort to improve therapeutic gain was assessed. Superficial, non perfused phantom tumors were fashioned in eight anesthetized mongrel dogs by transplantation of the spleen from the abdomen to a subcutaneous site on the hind limb. After pretreatment of the animal with the vasodilator hydralazine (0.5 mg/kg, IV) to enhance normal tissue perfusion, the spleen implant was heated with a 2450-MHz microwave diathermy apparatus, first with the animal's core body temperature in the normal range (39°C) and then after the animal had been packed in ice to reduce core …

Final Design Report Of The Design Of A Climate Controlled Sleeping Chamber For Infants And Toddlers, Jennifer Stenger Stevens

Undergraduate Honors Capstone Projects

A climate controlled sleeping chamber, or air crib, for infants and toddlers is an alternative sleeping medium to the conventional crib. It is a chamber that is ventilated with air that is temperature and humidity controlled to provide an optimum sleeping environment for young children, ages 0 to 2 years. Its purpose is to enhance the psychological and physiological development of young children. Because it is easier to heat a small chamber than larger living quarters, the air crib also has economic advantages.

The design o climate controlled sleeping chamber must meet some minimum requirements. The system must provide an …
