Abandoned Automobiles :A Case History Of Land Pollution, Robert William Arden
Abandoned Automobiles :A Case History Of Land Pollution, Robert William Arden
Masters Theses
"A study has been made of the abandoned automobile problem as it now exists throughout the United States with particular emphasis on the problem in the Saint Louis area. The primary goal of this study was to determine those factors which most influence the collection and disposal of derelict vehicles. The problem was examined in the following major areas: (1) The history of the problem in the Saint Louis area and the various attempts made to correct it, (2) the various businesses directly involved with the disposal of junk automobiles, namely, the auto wreckers and the scrap processors, and (3) …
The Closed Cycle-External Combustion Engine And Air Pollution, Galen Lee Pearson
The Closed Cycle-External Combustion Engine And Air Pollution, Galen Lee Pearson
Masters Theses
"The impact of the internal combustion engine on the air pollution problem in this country was presented and alternative propulsion systems for the land transportation vehicle were investigated. The potential characteristics of the more promising closed cycle-external combustion engine concepts were established and discussed. The closed thermodynamic power cycles analyzed include the Rankine, Stirling, and Feher supercritical cycles. Thermodynamic property data on eighteen candidate working fluids for the Rankine and Feher supercritical power cycles have been assembled and were presented in a utilizable form. The thermal efficiency (ratio of the net work out to the heat input) and the many …
Metabolism Of 3-Iodotyrosine And 3,5-Diiodotyrosine By Thyroid Extracts, Shih-Ying Sun
Metabolism Of 3-Iodotyrosine And 3,5-Diiodotyrosine By Thyroid Extracts, Shih-Ying Sun
Masters Theses
"A porcine thyroid enzyme was extracted from thyroid tissue by homogenization and differential centrifugation. The enzyme was capable of metabolizing both 3-iodotyrosine and 3,5-diiodotyrosine. All of the thyroid subcellular particles produced a fluorescent compound when incubated with these substrates. When the 1,000 x g sediment was supplemented with the 48,000 x g supernatant a second compound was formed. The compound was UV absorbing and has been identified as either 3-iodo-4-hydroxybenzaldehyde or 3,5-diiodo-4-hydroxybenzaldehyde depending upon which substrate was used. The 1,000 x g sediment was solubilized with 1% Conoco 1012-6 detergent. The activating factor in the 48,000 x g supernatant was …
Recovery Of Trace Organic Pollutants By Solvent Extraction And Freeze Concentration, William Chih-Wen Chang
Recovery Of Trace Organic Pollutants By Solvent Extraction And Freeze Concentration, William Chih-Wen Chang
Masters Theses
"The objective of this investigation was to evaluate the use of batch type solvent extraction and freeze concentration in recovering trace organic pollutants from water. The work was performed using a simplified water system containing known concentrations of phenol, and natural water systems collected from three sources (Meramec Spring, Gasconade River near Jerome, and Missouri River in Jefferson City) with different levels of pollution. The simplified water system was used to evaluate the effect of the number of extractions, solvent to sample ratio, extraction time, initial organic concentration, pH, and turbidity on solvent extraction; and the effect of volumetric concentration …
A Study Of The Effects Of Added Solid-Liquid Interfacial Area On The Stabilization Characteristics Of Simulated Wastewater Stabilization Lagoons, Gary Lee Gaines
A Study Of The Effects Of Added Solid-Liquid Interfacial Area On The Stabilization Characteristics Of Simulated Wastewater Stabilization Lagoons, Gary Lee Gaines
Masters Theses
"Wastewater stabilization lagoons have recently become a popular and efficient method of sewage stabilization in many parts of the country. The purpose of this investigation was to determine the effect of added solid-liquid interfacial area on the treatment capabilities of simulated wastewater stabilization lagoons. The simulated lagoons consisted of six -15 gallon aquariums which were operated in the laboratory. The solid-liquid interfacial area was increased in four of these lagoons by suspending plastic panels in the aquariums. The lagoons were operated for a period of approximately two and a half months using dehydrated milk as a simulated waste substrate. During …
Removal Of Phosphate By Sorption On Activated Alumina, Checkman Michael Yue
Removal Of Phosphate By Sorption On Activated Alumina, Checkman Michael Yue
Masters Theses
"The purpose of this investigation was to study the removal of phosphorus from waste water by sorption on activated alumina, and determine the capacity of the alumina to sorb phosphates in the presence of other ions, the effect of the influent flow rate and phosphorus concentration on the efficiency of the process, and the feasibility of regeneration of the used alumina. The studies were conducted using deionized and tap water to which inorganic phosphate had been added, and secondary effluent from bench-scale activated sludge units. They involved batch tests employing three types of activated alumina, ALCOA XM (minus 325 mesh), …
An Investigation Of Mining Effluent And Water Quality In The "New Lead Belt" Of Southeastern Missouri, Hong Wen Chen
An Investigation Of Mining Effluent And Water Quality In The "New Lead Belt" Of Southeastern Missouri, Hong Wen Chen
Masters Theses
"A field and laboratory investigation was carried out to collect background data for stream water quality in the New Lead Belt of Southeastern Missouri. The parameters measured were temperature, hydrogen ion concentration, hardness, alkalinity, turbidity and fluorides. A prolific algal and microbial growth was found in Bee Fork Creek which receives the mining and milling wastewater effluent from the Fletcher Mine. The laboratory studies were conducted to examine the biological effects of the organic flotation reagents used in the mining operations. The studies included Gram staining of bacteria, antimicrobial effects of milling reagents, bacterial fermentation tests of sodium isopropyl xanthate …
A Study On The Feasibility Of Using Pipelines For The Collection And Transportation Of Urban Solid Wastes, William Leo Sago Jr.
A Study On The Feasibility Of Using Pipelines For The Collection And Transportation Of Urban Solid Wastes, William Leo Sago Jr.
Masters Theses
"This study was conducted to determine the technological feasibility of using a tube transport (pipeline) system to supplement and partially eliminate the present inadequate solid waste collecting and transporting techniques employed in most cities throughout the United States. Specific objectives were to develop a practical pipeline system for the transport of refuse by means of a fluid and to determine the uniformity of composition of refuse. The hydrodynamic characteristics of each transport medium, water and Chemical Emulsion., W-4088, were to be determined also. Another item of interest was the degree of grinding necessary to transport refuse by pipeline. An experimental …
