The Influence Of Anaerobic Pretreatment On The Treatability Of A Milk Waste, Jerry Lee Siegel Feb 1969

The Influence Of Anaerobic Pretreatment On The Treatability Of A Milk Waste, Jerry Lee Siegel

Electronic Theses and Dissertations

Both anaerobic and aerobic treatment of wastewater has been used for many years. Some of the common aerobic treatment systems include oxidation or stabilization ponds, activated sludge, trickling filters, and aerated lagoons. Anaerobic treatment has been most commonly used for digestion of sewage sludge. However, septic tanks, anaerobic lagoons, and anaerobic activated sludge (contact stabilization) units are used to treat wastewater anaerobically. More recently, the two systems have been used in combination, with the anaerobic system preceding the aerobic one. This type of treatment has been used primarily for lagooning of industrial wastes, and most commonly for meat-packing wastes. In …

Isolation Of Keratinophilic Fungi From Soil And Wild Animals In South Dakota, William Urban Knudtson Jan 1969

Isolation Of Keratinophilic Fungi From Soil And Wild Animals In South Dakota, William Urban Knudtson

Electronic Theses and Dissertations

Very little is known of the ecology of keratinophilic fungi in animal populations and their habitats in South Dakota. Recent investigation of an outbreak of ringworm in blue foxes on a fur farm in South Dakota indicated that the source of infection may have been wild animals which had been captured and raised in the kennels previous to occupancy by the foxes. In recent years, a number of investigators have demonstrated that small and large mammals may carry keratinophilic fungi in their coats (13, 29-31, 52, 56-60, 63, 70, 77) and have postulated on the role of infected animals in …

Scheduling And Position Control Of Hospital Personnel, Larry Eugene Schmidt Jan 1969

Scheduling And Position Control Of Hospital Personnel, Larry Eugene Schmidt

Electronic Theses and Dissertations

A review of the literature indicates that previous studies have not provided an effective scheduling technique which will comply both with the restrictions of a set weekend-off sequence and of modern employment laws. Most hospitals are required to comply with the wage and hour laws of their state and, therefore, must schedule within this restriction. In a large number of cases, the hospital and the staff members have agreed upon some set weekend off sequence, thus placing an additional restriction on the scheduling procedure. The concept of position control is not mentioned in the literature. Preliminary investigation by this author …

Cell-Wall Analyses Of Diphtheroids Isolated From Cattle And Swine, Everett E. Scheetz

Electronic Theses and Dissertations

Biever, working in this laboratory, isolated numerous diphtheroidal organisms from cattle and swine sources. These anaerobic diptheroids were morphologically similar to organisms in the genera Corynebacterium and Actinomyces. King and Meyer found that isolates of anaerobic diptheroids from human sources were more closely related to the Corynebacterium based upon metabolic and serologic differentiation. Their work consisted of separating A. bovis from several isolates of anaerobic diptheroids on the basis of the catalase test, litmus milk reactions, and the fermentation of xylose, salicin, and raffinose. However, Grasser reported that the fermentation reactions are variable and cannot be used as definite criteria …

Cost Analysis Of Precast Prestressed Composite Pavement On U.S. Highway 14-Bypass, Wayne R. Haug

Electronic Theses and Dissertations

Because of the increase in heavy truck traffic, the need has developed for a stronger pavement to carry increasing wheel loads. These loads have usually resulted in thicker pavements which increases the cost. In some parts of the country the aggregates needed for pavements are scarce, making it necessary to transport the aggregates over long distances to the construction site. This longer haul increases the pavement cost and makes it necessary to investigate other methods of construction. A recent pavement development utilizes prestressed concrete. Prestressed concrete is composed of concrete prestressed with high strength steel. Concrete has a high compressive …

Wedge Flows Of Power-Law Fluids, Joseph H. Cothern Jan 1969

Wedge Flows Of Power-Law Fluids, Joseph H. Cothern

Electronic Theses and Dissertations

Many solutions exist for the laminar boundary-layer flow of Newtonian fluids. This is verified in literature by Schlichting. However, some fluids do not obey the Newtonian postulate that the stress tensor is directly proportional to the rate of deformation tensor. It is as likely, in fact, that non-Newtonian fluids could be pumped into an industrial complex as the more common Newtonian fluids. This is partly due to the growing use of synthetics and petroleum products in modern day living. The use of non-Newtonian fluids, however, does not have to be limited to problems of internal flow. The fluid in the …
