Meeting Wastewater Discharge Standards By Use Of High-Rate Infiltration-Percolation Basins, Larry D. Demers

Electronic Theses and Dissertations

Two fundamental problems have been associated with the use of large quantities of water – depletion and deterioration in quality. Present advanced wastewater treatment technology has shown that tertiary treatment of wastewater can produce high quality effluents, but large amounts of energy and chemicals must be sacrificed. An alternative to these costly systems is the land treatment system, which utilizes the soil mantle as a multiprocess “living filter” (2). Infiltration-percolation, a land treatment method, can be used for the reclamation of large quantities of wastewater. The infiltration-percolation advance treatment system has been investigated extensively by the Civil Engineering Department at …

Distribution, Age, And Growth, And Feeding Ecology Of Paddlefish (Polyodon Spathula) In Unaltered Missouri River, South Dakota, Rudolph S. Rosen

Electronic Theses and Dissertations

Four hundred eighty-four paddlefish (Polyodon spathula) were captured 26 June 1975 to 11 August 1976 from an unaltered stretch of Missouri River in South Dakota. Vital statistics were measured on all fish, 171 were sacrificed during the analysis of food habits, and 301 fish were tagged and released. Paddlefish were located by observation, gill netting, and snagging. Paddlefish were primarily found downstream from submerged sandbars from late spring to early fall. The crests of the sandbars were 0.1 to 1.0 m deep and immediately downstream, the depth was 1.5 to 4.5 m, and the current velocity was 0 to 0.3 …

Drip And Sprinkler Irrigation Of Carrots And Onions, James D. Melstad

Electronic Theses and Dissertations

Many specialty crops, especially vegetables, are shallow rooted and sensitive to periods of moisture stress. This makes irrigation of vegetables necessary to their production in South Dakota since summer rainfall is normally both inadequate and undependable. A study was initiated in conjunction with the South Dakota Agricultural Experiment Station and the Water Resources Institute to evaluate irrigation of specialty crops in eastern South Dakota. Drop and sprinkler irrigation were utilized for the irrigation of two specialty crops presently grown in South Dakota, carrots and onions. The study was initiated with the following objectives: 1. To compare carrots and onion yields …

High-Rate Infiltration-Percolation Treatment Of Wastewater To Satisfy Effluent Requirements, Dayton H. Alsaker

Electronic Theses and Dissertations

The treatment of wastewater to alleviate our freshwater needs and protect the environment at a reasonable cost is a major problem in the world today. The application of partially-treated wastewater to the land may be one method of solving this problem. Land application is neither a new concept, nor one that will solve all treatment problems, but it is likely to play an ever-increasing role in water pollution control planning. The Water Resources Institute at SDSU sponsored the project in its initial year of 1974. During this time much of the construction of the three infiltration percolation basins was completed. …

Computer Simulation Of Livestock Housing Design, Leslie Lloyd Christianson

Electronic Theses and Dissertations

Computer simulation requires theoretical and empirical mathematical relationships describing different aspects of heat and moisture transfer for livestock confinement buildings. Relationships with various degrees of sophistication exists that adequately describe these heat and moisture transfers. Using these relationships with climatic data, environmental requirements, construction characteristics, material properties and economic data, a computer technique can be developed to mathematically model energy requirements for operating confinement livestock environments. This technique should base ventilation rates on moisture removal, temperature control and animal comfort criteria to minimize unnecessary energy consumption. However, no such computer model currently exists that determines and employs optimal ventilation rates …

Electrical Safety In The Hospital, William Ray Engle

Electronic Theses and Dissertations

Electrical safety has become n important part of hospital management. The potential danger to patients and staff has increased, as health care becomes more sophisticated. Due to the unique situation that exists in hospitals, most hospital personnel do not understand the problems that occur. The problem is greater in smaller hospitals that do not have the time, money or qualified personnel to deal with the problem. Hospital electrical safety is not a complex problem. A basic safety program can be initiated if the personnel have a basic understanding of electricity and its effects on the body. Many nurses in the …

Corn Desiccation As A Means Of Reducing Drying Cost, Steven Earl De Hoogh

Electronic Theses and Dissertations

A dramatic increase in the cost of petroleum and an awareness that petroleum supply is limited has occurred during the past few years. The increased cost of petroleum products has increased farmers’ production costs. Furthermore, the limited supply of petroleum products has focused attention on ways of conserving energy. Researchers are looking for ways to harness “new” forms of energy and to make them available to consumers as a reasonable cost. Solar energy is one of the “new” forms of energy that is being studies extensively. Solar heaters are being evaluated to supplement conventional corn dryers. Nevertheless, solar drying is …

Physiological Responses And Thermal Comfort Of Subjects In A Tractor Cab, Kenton Richard Kaufman

Electronic Theses and Dissertations

P.O. Fanger of Denmark was the first scientist to generalize the physiological basis for predicting human thermal comfort based on activity level, clothing type, air temperature, air velocity, mean radiant temperature, and air humidity. Thus any activity level and clothing type, it is possible to determine combinations of air temperature, mean radiant temperature, air humidity and relative air velocity which would produce optimum thermal comfort. The Fanger approach has been applied successfully to offices and buildings. It would be quite useful to demonstrate that Fanger’s concepts could be applied to tractor cabs. The objectives of this study were as follows: …

Edge Detection And Adjacency Classification In Digital Data Via The Gradient Vector, Michael John Russell

Electronic Theses and Dissertations

Detection of edges in imagery represented by the matrix of data and classification of the data surrounded by an edge are investigated. An edge detection algorithm is developed and used to locate edges in digitized imagery. An algorithm called the adjacency classifier is developed to classify all groups in adjacent data points that are surrounded by edges. These two algorithms incorporate three important characteristics of the gradient vector: high gradients are inherent at edges, low gradients are inherent at edges, low gradients are inherent within homogeneous objects and gradient vector directions are perpendicular to the edge direction. Computer programs which …
