Survival, Growth, And Food Habits Of Brook Trout Introduced Into An Eastern South Dakota Stream, Larry W. Kallemeyen

Electronic Theses and Dissertations

Brook trout were introduced into the South Fork Yellow Bank River, an eastern South Dakota stream, on October 11, 1966. A supplemental brook trout plant was made on June 8, 1967. Survival for the initial plant from October, 1966 through October, 1967 was 2.4%. Survival for the supplemental plant from June, 1967 through October, 1967 was 21.0%. Trout from both plants took part in spawning activities during the fall of 1967. Average length of trout from the initial plant increased 9.8 cm during one year. Their average condition factor reached a peak in June, 1967 after being low throughout the …

Movements And Behavior Of Pheasants During The Breeding Cycle As Determined By Radio-Tracking, Thomas L. Kuck

Electronic Theses and Dissertations

Behavior and movement studies were carried out on the Rifle-Calahan Study area, Sanborn County, South Dakota, in 1965 and 1966. Objectives of the study were to evaluate radio telemetry techniques, determine the territorial area and home range of the hen and cock, study the behavior pattern of hen and cock in the harem makeup, determine the distance traveled by the hen when attracted to the harem, determine if the hen nests in the immediate area of the crowing territory, and study the behavior of the hen while nesting and caring for the brood. Twenty adult pheasants (16 hens and 4 …

Web Buckling Of Delta Girders, Franklin P. Wang

Electronic Theses and Dissertations

In reviewing the papers in the literature concerning delta girder bridges, 1,2,3, it is frequently found that investigations were not carried far enough to be useful for actual design in engineering offices. This is attributed mainly to one or both of the following reasons: 1. The successful outcome of test results were not based on a sound theoretical analysis of the behavior of the delta girder. 2. The investigations did not give detailed theoretical and experimental studies to obtain the optimum size and geometry of the delta girder. The delta girder consists of the same basic cross section as the …

A Survey Of School Districts In Boyd County, Nebraska, 1965-1966, Robert Stuerman

Electronic Theses and Dissertations

Today, due to the ever-increasing educational requirements laid down by states and the increasing costs of education, many of the smaller districts have either been forced to close down or are lacking in one or more of the state requirements and are on the verge of losing their accreditation and ultimately their school. Dennis M. David made a survey of 135 citizens in five mid-western states and showed that only one-fourth of the people were aware that the purpose of reorganization of school districts is to provide better education. It has been shown through surveys of Nebraska County high school …

Experimental Analysis Of Free Convection Heat Transfer From A Nonisothermal Plate, Lloyd Edwin Stoebner

Electronic Theses and Dissertations

Heat transfer by convection has been studied extensively since about 1900, but it is probably still the least understood of the three types of heat transfer due to its dependency on fluid dynamics. The most thoroughly studied cases are forced convection over a flat plate and free convection from a vertical isothermal plate. In a large number of engineering applications, it is necessary to calculate the heat transfer from a surface which is heated locally such as a fin heated at its root. There has been very little analytical or experimental work done for this particular case in which the …

Turbulent Velocity And Temperature In The Mixing Region Of Two Parallel Airstreams, Olin Thomas Sessions

Electronic Theses and Dissertations

Two basic types of fluid motion are known, laminar and turbulent flow. Laminar flow is characterized by essentially uniform flow of fluid particles and obedience to Newton’s Viscosity Law, ¬ƒ=µdu/dy. Many fluids have been found to have dynamic viscosities (µ) which are essentially constant and are considered to be properties of the fluid. The viscosities of gases can even be derived by the kinetic theory of gases and are found to be functions of the mean free path of individual molecules. Turbulent motion, on the other hand, can be described as a flow made up of macroscopic lumps of fluid …

Incomplete Neurological Development As A Root Of Reading Problems: A Classroom Teacher's Approach, Helen B. Prokes

Electronic Theses and Dissertations

Incomplete neurological development as a root of reading problems is a concept that could revolutionize our system of education. It could guide us to treating the “disease” rather than the symptoms. It could save us much “beating of the air” in our use of methods. It could modify our demands that learning take place in developmental infancy. At least, that is the theory of Dr. Carl H. Delacato2 and his associates in their Developmental Reading Program at Chestnut Hill Academy in Philadelphia, Pennsylvania. Their motivation stems from the conviction that “reading problems need not exist at all because they can …

A Group Theoretical Method Of Treating Polyhedral Molecules With Spin State Eigenfunctions, Richard C. Mullaney

Electronic Theses and Dissertations

The object of this thesis is to examine a basic deficiency in the valence bond theory as developed by Heitler, London, Slater and Eyring and to offer an alternate general approach that leads to a greater reduction of the secular determinant for some molecular structures. It is observed that in the formation of independent valance bond eigenfunctions, there exists an implicit assumption that one is working with planar or near-planar molecules. But when a polyhedral structure is considered, it is found that the independent valence bond eigenfunctions are no longer suitable basis functions for the symmetry group of the structure. …

Planned Educational Progress In The Mitchell Public School System, Donald Jesse Mclean

Electronic Theses and Dissertations

There is but one major purpose for the existence of the public schools in the American society. That purpose is to provide the best possible education for the nation’s children. Several elements are required to make this successful program a reality within a given community. The school board and administration must provide for at least three important ingredients, the first being a system of well-designed school buildings. The second is the employment of well- prepared teachers and the third is a well-planned curriculum. To accomplish a successful program it is necessary to continually evaluate all three areas. In doing so …

A Follow-Up Study Of South Dakota State University Graduates With A Major In Industrial Arts 1951 Through 1966, Robert Vernon Lee

Electronic Theses and Dissertations

Education is not an end in itself. It is only a means to an end. This end is usually away from the educational institution itself. There are no doubt several methods for evaluating the effectiveness that the educational institution is achieving in its endeavor to prepare its graduates toward the desired goals. The degree of proficiency in the individual subjects can be tested while the student is in school. How the person is doing after graduation is a major part of the true test of his overall education. Evaluation becomes more difficult after the student has graduated. This is due …

Analysis Of Heat Transfer From Circular Or Square Fins, Yun-Seng Huang

Electronic Theses and Dissertations

It has been recognized that an increase in the rate of heat transfer to or from a solid body can be accomplished by extending surfaced called fins. There are a variety of fins such as rectilinear or parabolic fins protruding from a flat wall, or thin circular or rectangular fins on a tube. In all cases the heat transfer designers are interested in the optimum heat loss or gain. Considerable experimental work has been done in order to establish the empirical values of convective heat transfer coefficient to predict the amount of heat transfer from a particular fin configuration. The …

Fox-Prey Relationships In Eastern South Dakota, Robert L. Drieslein

Electronic Theses and Dissertations

Relationships between red foxes (Vulpes fulva) end their principal prey, particularly ring-necked pheasants (Phasianus colchicus), were studied on four units in eastern South Dakota from December 1964 to September 1966. Each unit was composed of a 100-square-mile "reduction area," on which fox populations were reduced, and a 100-square-mile "check area," on which fox populations were not reduced for the study. Indices to populations of foxes, pheasants, mice, eastern cottontails (Svlvilagus floridanus) and whitetail jackrabbits (Lepus townsendi) were obtained and used to evaluate food habits and the effect of predator reduction on prey populations. Four-hundred seventeen stomachs and 104 female reproductive …

Movement Of Forage Fishes In A South Dakota Stream, Thomas P. Felix

Electronic Theses and Dissertations

Movement patterns of Semotilus atromaculatus, Rhinichthvs atratulus, Campostoma anomalum and Catostomus commersoni were investigated in an eastern South Dakota stream for a period of one year. Electrofishing, fin clipping and a multiple census method were employed. Population structures were estimated for each species. Populations were considered unstable due to the occurrence of appreciable emigration and immigration between sampling periods. Differential size class mobility was established for all species. Species exhibited upstream movement tendencies during the summer and more random movement tendencies during the fall. Size classes of S.atromaculatus, R. atratulus, and C. anomalum showed differential upstream movement affinities. Considerable growth …

Seasonal Movements Of Prairie Grouse In South Dakota, Warren W. Jackson

Electronic Theses and Dissertations

From 1962 through 1966, 1,401 plains sharp-tailed grouse (Pedicecetes phasianellus jamesi) and greater prairie chickens (Tympanuchus cupide pinnatus) were trapped in Gregory and Lyman Counties in south-central South Dakota. Cannon-projected nets and funnel traps were used to capture prairie grouse on breeding grounds and winter baitsites. Some birds were marked with backtags and leg-markers. Movement information was obtained from field observations, hunter reports, sharp-tailed grouse collections, and by recapturing banded birds. Male birds moved less than two miles from winter baitsites to breeding areas; most movements over five miles were made by immature female birds. Seventy-seven percent of the hunter …

Inelastic Behavior Of Steel I-Beams With Hexagonal Web Cutouts, Teresa Chen Wang

Electronic Theses and Dissertations

In recent years plastic analysis has been widely used in structural design throughout the United States. It is based on the maximum load-carrying capacity of the structure. It offers a more realistic design approach than the conventional elastic methods, where the true factor of safety against ultimate strength can and does vary significantly from one structure to another.

The main objective of this study is to determine the maximum load-carrying capacity of steel I-beams with hexagonal web cutouts. When the cutouts are arranged as shown in Figure 1-a, the beam presents an appearance exactly as does a castellated beam. A …

This treatise will be concerned with the formulation and implementation of the Title I program at Whittler Junior High School in Sioux Falls, South Dakota, during the summer of 1966. The Title I program at Whittler Junior High ls one of the many innovations to be found in this program of federal aid to education. The range of programs acceptable under Title I is as great as the ingenuity of individual administrators and teachers. Of course, certain specifics must …

Effects Of Dieldrin On Reproduction Of Penned Hen Pheasants, Thomas Donald Atkins

Electronic Theses and Dissertations

Pen studies to determine the effects of dieldrin on reproduction of the hen pheasant were conducted for two breeding seasons, Hen pheasants were caged individually and administered encapsulated dieldrin at weekly intervals. The first season, treatment levels were 0, 2 or 4 mg of dieldrin per hen per week. Hens receiving 4 mg weighed more and laid heavier eggs than the controls. However, these differences were not attributed to the effects of dieldrin, but to the condition of the hens when first treated. Hatchability of eggs from the 2 mg group was significantly higher for an undetermined reason. Feed consumption, …

Minimum Resource Requirements For Specified Levels Of Income In Faulk County, South Dakota, Dwaine Edward Umberger

Electronic Theses and Dissertations

The purpose of this study is to determine combinations of agricultural resources and enterprises required to obtain specified farm income levels in Faulk County, South Dakota. The income level of the farmer in Faulk County depends on the quantity and quality of the resources controlled and the efficiency achieved in utilizing these resources. The level of farm income in Faulk County is often inadequate to meet both the requirements of the farm firm and the needs or desires of the operator and his family. Many farmers are making adjustments to increase their income levels.
