Criteria For Determining Feasibility Of Rural Water Supply Systems In Livestock Production Areas, Lynn L. Peterson

Electronic Theses and Dissertations

Feasibility guidelines for proposed and existing community rural water supply systems have been developed around such parameters as population density, size of group, and ability to repay. However, these guidelines were based on more densely populate areas where water is used primarily for domestic purposes. These guidelines do not necessarily fit situations where population density is low and water availability enters in as a factor of livestock production. It is apparent that guidelines need to be developed for such situations. With this intention, the objectives of this study were established as follows: 1. Determine what criteria are pertinent to the …

The Relationship Of Freestyle Sprinting Ability In Swimming To Selected Measurable Traits, Keith Charles Sutton

Electronic Theses and Dissertations

Through reading previous studies, corresponding and talking with respected swimming coaches, and drawing from personal experience, the present writer identified and tested physical traits thought to influence a swimmer’s speed. Although muscular strength of the arms and good flexibility have long been accepted by most coaches as an asset to the speed swimmer, the other variable were selected on the basis of their anticipated relationship to swimming speed. The purpose of this study was to investigate, by means of objective tests, the relationship of selected physical characteristics to performance by swimmers in a forty-five yard freestyle sprint.

Encephalitis Epidemiology In South Dakota : The Development And Use Of An Encephalitis Simulation Model And A Computerized Human Serum Bank To Determine Western And St. Louis Encephalitis Activity, Curtis Dean Wilson

Electronic Theses and Dissertations

The investigation reported here represents an attempt to relate a virus vector simulation model with field observations made in South Dakota over the past years. The viruses that will be examined are two encephalitis viruses, western equine encephalitis (WEE) and St. Louis encephalitis (SLE). Since the encephalitis viruses are grouped within the arboviruses, viruses transmitted by an arthropod vector, any epidemiological study of the human and horse encephalitis outbreak process must include a study of the vector, in this case mosquitoes, and the factors affecting that vector. It is this complex relationship of virus, vector and hosts that led those …

Integrated Numerical Simulation Of Drip Irrigation With Subsurface Drainage, James Ray Hoover

Electronic Theses and Dissertations

A numerical method and model were developed to simulate soil moisture during steady-state and transient flow toward a tile drain. Intermittent application of water by drip irrigation and rainfall were simulated by use of finite difference approximation equations. No known analytical solution for these flow situations exists because of the complex mathematics describing unsaturated flow in the soil. The computer model is based on the electrical resistance network analog. The explicit finite difference equations were solved by the successive over-relaxation method for steady-state flow and by iteration for transient soil moisture flow. The computer program for the model consists of …

Relationships Of Scores Achieved On A Crawl Stroke Rating Form And Selected Measures Of Stroke Efficiency In Swimming, Bradley Laverne Erickson

Electronic Theses and Dissertations

The continuous surpassing of records is an indication that performances in competitive swimming are steadily improving. Success in competition depends upon a swimmer’s ability to “maintain a high velocity over time.” Factors which determine the ability to maintain high velocity include muscle endurance, efficiency, and total capacity for energy expenditure. Though various training methods, the swim coach has been able to increase physiological change in his athletes, including muscular endurance. A valid measure for determining energy expenditure is through analysis of data obtained by testing for oxygen consumption. There is also a linear relationship between oxygen consumption and heart rate. …
