Soil Infiltration Tertiary Treatment Of Stabilization Pond Effluent, Charles Allan Tiltrum
Soil Infiltration Tertiary Treatment Of Stabilization Pond Effluent, Charles Allan Tiltrum
Electronic Theses and Dissertations
Whenever man begins to alter these naturally occurring events, problems arise which must be answered. In the case of engineered soil systems, it is the engineer who must cope with these problems. As discussed later in the review of literature, previous studies conducted on similar types of soil at different locations have revealed different infiltration rates and quality improvements. These contrasting results have indicated that data obtained from other studies cannot be used to reliably predict the infiltration rates or improvements in water quality for soils at different locations. Due to the complex nature of the different soil types and …

The Economic Feasibility Of Confinement Feedlots And The Analysis Of Seasonal Marketing Variations For Feeder Cattle In South Dakota, Daniel W. Francke
The Economic Feasibility Of Confinement Feedlots And The Analysis Of Seasonal Marketing Variations For Feeder Cattle In South Dakota, Daniel W. Francke
Electronic Theses and Dissertations
South Dakota apparently produces an adequate quantity of feeders and feed grains to substantially increase slaughter cattle production. Furthermore, South Dakota prices for feed grain, roughage, and feeder cattle are equal to, or less than, the prices for these inputs in other areas where cattle feeding has flourished in recent years. It should also be determined how South Dakota farmers might increase fat cattle production. Therefore, in an attempt to explain South Dakota's slow cattle feeding growth and possibly help farmers in South Dakota and neighboring areas develop the cattle feeding industry, the following problems were researched. First, this area …

Opportunity Costs Of Diverting Water From Agriculture To Industry In Portions Of Northeastern Wyoming, Woodrow Elbert Murray
Opportunity Costs Of Diverting Water From Agriculture To Industry In Portions Of Northeastern Wyoming, Woodrow Elbert Murray
Electronic Theses and Dissertations
Studies have been made on the feasibility and cost of diverting water both within and to Northeastern Wyoming. Estimates -for diverting water from the Powder River, including Crazy Woman and Clear Creeks, to the Gillette (Campbell County) area range from an annual water supply of 251,000 to 53,000 acre-feet, with dam construction costs of 6 to 59 million dollars. The annual water costs per acre-foot for delivery from the reservoirs to Gillette range from 76 to 99 dollars. Presumably the water would be taken from the unused and unappropriated water supply. Estimates for diverting water from the Tongue River for …
Population Change In West Africa : 1954-1972, Ndidi Odashionu Okwumaba
Population Change In West Africa : 1954-1972, Ndidi Odashionu Okwumaba
Electronic Theses and Dissertations
In the light of recent concern over world population growth, it would be interesting to study to what extent West Africa as a developing area has experienced changes in fertility, mortality and natural increase. This study would be especially interesting in that developing countries like those in West Africa account for approximately two-thirds of the world's population. Students of demography generally hold that as a rural agricultural country becomes more urbanized and industrialized, a transition also occurs in the demographic process. Under the influence of modernization, death rates decline rapidly while high fertility continues, producing a rapid population growth that …

A Study Of Engineering Services For South Dakota Hospitals, Duane Robert Nelson
Electronic Theses and Dissertations
The hospitals in South Dakota, like all other hospitals, need engineering services for efficient and economical operation. Presently, about one-half of the hospitals licensed by the State Health Department are accredited by the Joint Commission on Hospital Accreditation. Mr. Norton, Administrator at Yankton's Sacred Heart Hospital, indicated that about one-half of South Dakota's hospitals are meeting the required standards, for hospital safety and equipment maintenance, of the Joint Commission on Accreditation of Hospitals. The larger hospitals in the state have personnel providing engineering services, but these larger hospitals comprise a small part or' the total health care facilities in the …
Improving Water Use Efficiency Of Smooth Bromegrass By Selecting For Regrowth, Delmer F. Gross
Improving Water Use Efficiency Of Smooth Bromegrass By Selecting For Regrowth, Delmer F. Gross
Electronic Theses and Dissertations
Sixty-nine genotypes, including 60 from the variety Saratoga smooth bromegrass, three from South Dakota 7 smooth bromegrass, and two each of reed canarygrass, orchardgrass, and creeping meadow foxtail as check species were selected for regrowth from a source nursery containing over 37,000 genotypes. In addition, four genotypes of Saratoga with poor regrowth capability were selected as checks. These 73 genotypes were placed in a greenhouse environment to evaluate digestibility (IVDMD), and other characteristics. After three harvests, 34 genotypes were vegetatively propagated in a field experiment to determine regrowth capabilities. NCE rates were not correlated highly with yield in the greenhouse …
An Economic Analysis Of The Impacts Of Weather Modification On Crop And Livestock Production In Southeastern South Dakota, James W. Dunn
An Economic Analysis Of The Impacts Of Weather Modification On Crop And Livestock Production In Southeastern South Dakota, James W. Dunn
Electronic Theses and Dissertations
The procedure used for the study was the application of linear programming to an aggregate farm. The characteristics of this aggregate farm were determined from data compiled by the South Dakota Crop and Livestock Reporting Service, with assistance from Dr. Wallace Aanderud and Dr. Richard Rudel, both with the Economics Department at South Dakota State University. The method of an aggregate farm approach was used because the desired estimates are of an aggregate nature. The activities were limited to their actual historical limits, in order to obtain results as representative of the actual effects of weather modification as possible. This …

Automated Recognition Of Human Speech : A System Survey, A Problem Analysis, And A Frequency Shift Experiment, David Robin Scott
Electronic Theses and Dissertations
This literature and experimental research was conducted in order to accomplish several objectives. First of all, the establishment of a historical background of speech recognition efforts was desired. This background would reveal the various basic approaches taken in the past to recognize speech. In addition, the disadvantages and contributions of each system would be noted in order to recognize and analyze the problems inherent in recognizing speech. Secondly, an analysis of the major problems blocking automatic speech recognition was desired not only to investigate these problems, but also to evaluate the state of their solutions. Thirdly, an experiment was performed …

Infiltration Basins For The Final Treatment Of Lagoon Effluent In South Dakota, Peter S. Johnson
Electronic Theses and Dissertations
The declared objective of the Federal Water Pollution Control Act Amendments of 1972 is "to restore and maintain the chemical, physical, and biological integrity of the Nations waters. " A schedule of required treatment is also· promulgated that calls for the equivalent of secondary treatment by July 1, 1977 and the best practicable waste treatment by July 11, 1983 for all publicly owned treatment plants. This Act serves notice that many existing wastewater treatment plants will have to be upgraded to meet the new federal regulations required by the Act. This, coupled with the already questionable quality of lagoon effluent, …

Permeability And Consolidation Characteristics Of Soils Producing Irregular-Shaped Compaction Curves, Terry L. Forest
Electronic Theses and Dissertations
Through many years of study, it has been found that one of the best methods of classifying soils is by strength, and the best and most economical method of obtaining strength is by compaction. By compacting a soil, the shear strength is increased permeability decreased, and future settlement or consolidation decreased. These properties. of' permeability and consolidation are important in the design of any structure whether it is a dam, single or multi-story building, bridge, highway, or lagoon. The engineer must be sure that the consolidation and permeability of the soil are such that the structure will be able to …
Experimental Study Of Noise Propagation In A High Velocity Flow Field, Ismail Tag
Experimental Study Of Noise Propagation In A High Velocity Flow Field, Ismail Tag
Electronic Theses and Dissertations
A great deal of effort has been devoted to the study of noise suppression in the jet engine air intake. Noise suppression by sonic choking is well known, but noise suppression by subsonic choking is less understood. Sound waves generated by the compressor fan are attenuated while travelling upstream in high Mach number flow. The limiting case is when a sonic plane is generated in the inlet. In this case, theoretically speaking, no sound waves can travel through the sonic plane. There are many factors which influence subsonic choking. The nonlinear behavior of the spinning waves generated by the compressor …
