Sudangrass Studies: Yield, Hcn Value, Nitrate Content, And Grazing Systems, Don T. Winch Mar 1967

Sudangrass Studies: Yield, Hcn Value, Nitrate Content, And Grazing Systems, Don T. Winch

Electronic Theses and Dissertations

The use of summer annual forage crops to supplement cool season perennial forages for grazing has become popular in the mid-western area of the United States. Sudangrass (Sorghum sudanese (Piper) Stapf.) is one of the most important sources of annual summer feed in this area. With the advent of more vigorous and well adapted varieties and hybrids the use of sundangrass has greatly increased. It produces high yields of good quality forage in a short period of time. Sudangrass makes its best growth during mid-summer when most pasture species are dormant or semi-dormant (14). It will tolerate long periods of …


Self-Estimate Of Proficiency In Parliamentary Procedure By Members Of The 1967 South Dakota State Legislature, Richard F. Whitman Mar 1967

Self-Estimate Of Proficiency In Parliamentary Procedure By Members Of The 1967 South Dakota State Legislature, Richard F. Whitman

Electronic Theses and Dissertations

Instruction in parliamentary procedure has long been a part of the curriculum in many schools of this country. Generally, this instruction has been associated with departments of speech; consequently, speech teachers have researched for methods of evaluating the effectiveness and the extensiveness of training that students receive in parliamentary procedure. Since parliamentary procedure is the operating code of most deliberative assemblies, the South Dakota State Legislature was chosen as a logical place to measure the practical application of techniques learned in parliamentary procedure courses. Because the effectiveness of a legislator may be somewhat dependent on how well he can employ …

Electronic Theses and Dissertations

The purpose of this investigation was to determine the effects of two types of resistance-training programs on the velocity of the baseball batting swing. A sub-problem of the study was to determine the effect on the velocity of the batting swing of using a weighted bat immediately prior to batting. The following procedure was employed: thirty freshman baseball candidates at the South Dakota State University were selected as subjects and were placed in two groups equated by the measure of the velocity of the baseball batting swing. The subjects in the two experimental groups (Traditional Weight Training Group and Resistance …


Supplemental Vitamins In The Drinking Water For Early Weaned Pigs And Growing Rats, Marvin Eugene Wastell Mar 1967

Supplemental Vitamins In The Drinking Water For Early Weaned Pigs And Growing Rats, Marvin Eugene Wastell

Electronic Theses and Dissertations

Vitamins are defined as organic compounds required in small amounts to perform many essential functions in the animal body. All vitamins have different structures and perform different functions. Experimental research has shown that it is very important to supply adequate amounts of vitamins to insure normal growth and body maintenance of animals. Swine producers use completely mixed diets or the free choice feeding of corn and supplement, which includes proteins, minerals, vitamins and additives, as methods of supplying supplemental vitamins for pigs. These two methods have been accepted by modern swine producers as good feeding programs because they have supported …


Web Buckling Of Delta Girders, Franklin P. Wang Mar 1967

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 …


Acetylene Inhibition Of Nitrogen Fixation By Klebsiella Pneumoniae M5al, Robert L. Todd Mar 1967

Acetylene Inhibition Of Nitrogen Fixation By Klebsiella Pneumoniae M5al, Robert L. Todd

Electronic Theses and Dissertations

The four most abundant elements needed to support plant growth are carbon, hydrogen, oxygen, and nitrogen. Of these carbon, hydrogen, and oxygen are available to the plant in ample supply from the atmosphere and soil. Nitrogen, however, is available only in limited quantities in a form useable to the plant. The nitrogen is usually supplied in the form of nitrates or ammonium-nitrogen. The largest supply of nitrogen is in the atmosphere but it is in the elemental, uncombined form. Few plants, if any, are able to convert, directly or indirectly, this atmospheric nitrogen to organic matter. Plants which assimilate elemental …


A Survey Of School Districts In Boyd County, Nebraska, 1965-1966, Robert Stuerman Mar 1967

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 Mar 1967

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 …

The application of mist to cauliflower and lettuce plants improved the quality of cauliflower heads. The mean temperature reduction in the mist plots was 4.8° F. Positive correlation of .76 was obtained between outside temperature and temperature under mist. By comparison of sample means of paired observations, differences were found to be significant at one percent level. The mist system was 2.5 feet above soil level. The lines were 120 feet long. The 3 lines on the west side of the plot were placed 3 feet apart. The next 7 lines were placed 6 feet apart. The last two lines …


A Study Of The Equalization Formula Of South Dakota's Minimum Foundation Program, Arthur K. Shaver Mar 1967

A Study Of The Equalization Formula Of South Dakota's Minimum Foundation Program, Arthur K. Shaver

Electronic Theses and Dissertations

In 1963, the South Dakota State Legislature passed a supplemental portion to the minimum foundation law. This section of the law1 provides support to school districts on a formula of equalization base on an individual school district’s need and effort. The law limits the amount of equalization support distribution to $2,000,000. In 1963, when the law was passed, foundation payment computations were not available on every district. Information necessary to evaluate the foundation program became available to educators and legislators in 1964 when payment were computed to districts for the first time. Problems in the mechanics of the formula became …


Turbulent Velocity And Temperature In The Mixing Region Of Two Parallel Airstreams, Olin Thomas Sessions Mar 1967

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 …

The track pill box method was used to denote designation …


An Analysis Of The Production Output Difference Between An 11-Pica And A 15-Pica Line Width When Type Is Set By The Tts Method, Larry E. Rolufs Mar 1967

An Analysis Of The Production Output Difference Between An 11-Pica And A 15-Pica Line Width When Type Is Set By The Tts Method, Larry E. Rolufs

Electronic Theses and Dissertations

Since the early 1940’s there have been few experiments dealing directly with line width, and even fewer studies dealing with the effect of line width on productions output differences. However, there has been considerable speculation, and many hypotheses, about these differences. In a 1969 study, Leicht studied output differences on manually operated typesetting machines, using 11 picas and 15 picas.30 In the same year, Nuckols investigated comparative reading times using the same measures.31 These studies supported the hypotheses of the Louisville Courier-Journal that a 15-pica line width make for a more readable newspaper, and that type can be set manually …


The Nature And The Influence Of The Work Of The Information And Education Section, South Dakota Department Of Game, Fish And Parks, Edward Riedl Mar 1967

The Nature And The Influence Of The Work Of The Information And Education Section, South Dakota Department Of Game, Fish And Parks, Edward Riedl

Electronic Theses and Dissertations

This paper deals with a study of an organization whose responsibility is to inform and educate people. This is a study of the program of the Information and Education Section, South Dakota Department of Game, Fish and Parks. There is much confusion connected with the terms “public relations,” “publicity,” and “public information.” Definitions of these terms will result in a better understanding of this study. Emery, Ault and Agee define public relations, “as the planned effort to influence and maintain favorable opinion through acceptable performance, honestly presented, and with reliance on two-way communications.”1 Public relations is also a management function. …


Incomplete Neurological Development As A Root Of Reading Problems: A Classroom Teacher's Approach, Helen B. Prokes Mar 1967

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 …


Interaction Of Shear And Bending On Light Gage Steel Diaphragms, Chandrakant D. Patel Mar 1967

Interaction Of Shear And Bending On Light Gage Steel Diaphragms, Chandrakant D. Patel

Electronic Theses and Dissertations

In the modern practice of design of structures a variety of problems confront the structural engineer. Whether he is involved in the area of aircraft structures (i.e. stressed skin structures) or complex immovable structures, the problems are seldom simple. In the design of stressed skin structures the complexity and the refinements of analysis methods, combined with the economics of weight saving, do create many problems to be solved. Interaction of multiple force systems are among the problems of the engineer. Many types of interaction occur in practical structures. Some interaction behavior is predictable though routine stress analysis such as the …


Feedlot Performance Of Heifers As Affected By Spaying And Hormone Treatment, Lowell James Nygaard Mar 1967

Feedlot Performance Of Heifers As Affected By Spaying And Hormone Treatment, Lowell James Nygaard

Electronic Theses and Dissertations

Thirty-three percent of the animals which comprised the fed slaughter market in 1966 were heifers (U.S.D.S., 1967). When heifers are compared to steers, the gain at a slower rate, require more feed under similar feeding systems and sell at a lower price. These are important economic considerations in view of the large number of heifers fed for slaughter. The meat from heifers has been shown to be equal to that of steers in eating quality. It, however, sells at a lower price because heifer carcasses tend to be fatter and to have more waste as fat trim than steer carcasses …


A Comparison Of The Anxiety Measures And Match Performance Evaluations Of High School Wrestlers, Richard Edward Newman Mar 1967

A Comparison Of The Anxiety Measures And Match Performance Evaluations Of High School Wrestlers, Richard Edward Newman

Electronic Theses and Dissertations

The purpose of this investigation was to determine if an individual high school wrestler’s anxiety measures would serve as an indicator of his match performance. The subjects were thirty-one varsity wrestlers who were in attendance at Brookings High School, Brookings, South Dakota, during the academic year 1966-1967. The top twenty-four wrestlers, as determined by weekly competitive challenge matches, received alternate forms of the IPAT 8-Parallel-Form Anxiety Battery forty minutes prior to the “A” and “B” teams’ competitive performances in all home wrestling matches. These tests were administered in order to measure the anxiety levels of subjects in a stress situation. …


A Group Theoretical Method Of Treating Polyhedral Molecules With Spin State Eigenfunctions, Richard C. Mullaney Mar 1967

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. …

An Economic Analysis Of The Effect Of Commercial Bank Credit On Economic Growth In South Dakota, Robert W. Mckellips Feb 1967

An Economic Analysis Of The Effect Of Commercial Bank Credit On Economic Growth In South Dakota, Robert W. Mckellips

Electronic Theses and Dissertations

Contemporary economic growth theories generally emphasize the importance of capital accumulation as requirement for growth. Capital accumulation is possible by diversion of a portion of present production from consumption into production of capital goods. If a portion is diverted from consumption, the dollar value of consumption goods available is less than the total income of the factors of production. The consumer is forced to forgo consumption and save part of his income. That portion of income which is saved by the firm may be directly invested because the firm is the investing institution. The savings of the other sectors must …


Planned Educational Progress In The Mitchell Public School System, Donald Jesse Mclean Feb 1967

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 …

Effects Of Continuous Running As Compared To Interval Running On Cardiorespiratory Efficiency Of Conditioned Freshman Wrestlers At South Dakota State University, Terry J. Linander

Electronic Theses and Dissertations

The purpose of this investigation was to determine whether a running program significantly influences the cardiorespiratory efficiency of conditioned wrestlers and to compare continuous running and interval running as methods of increasing the cardio-respiratory efficiency of conditioned wrestlers. Eighteen of the 19 members of the freshman wrestling squad at South Dakota State University, Spring Semester 1967, volunteered as subjects. The 18 subjects were divided into three equated groups, the results of a cardiorespiratory efficiency test being used as the equating factor. By employing the track pillbox method, the three equated groups were designated as the Interval Running Group (IR), and …


Investigation Of Combine Header Losses During Grain Sorghum Harvest, Vern Earl Matter Feb 1967

Investigation Of Combine Header Losses During Grain Sorghum Harvest, Vern Earl Matter

Electronic Theses and Dissertations

The source and exact date of the introduction of grain sorghum into the United States has not been agreed upon, but it is generally agreed that it was sometime during the middle of the nineteenth century. The taller cane varieties were widely grown for syrup, sugar, and forage, but the strictly grain varieties were not accepted into the grain belt region until the 1950’s. It was at this time that the shorter varieties, those which could be harvested with a conventional combine, were sufficiently improved to compete with corn as a grain crop. Grain sorghum’s characteristics; being more resistant to …


A Follow-Up Study Of South Dakota State University Graduates With A Major In Industrial Arts 1951 Through 1966, Robert Vernon Lee Feb 1967

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 …


Feedlot Performance Of Hereford And Holstein Steers As Affected By Ration And Slaughter Weight, William M. Larson Feb 1967

Feedlot Performance Of Hereford And Holstein Steers As Affected By Ration And Slaughter Weight, William M. Larson

Electronic Theses and Dissertations

In 1918 the Bureau of Markets, now the Bureau of Agriculture Economics, of the United States Department of Agriculture inaugurated its market reporting service on livestock in Chicago. At that time a uniform standard was set up for market classes and grades of cattle. The use of these uniform descriptions for all classes and grades of cattle throughout the country by researchers, producers, selling and buying agencies and packers has contributed a great deal to the orderly marketing of cattle and to the reporting and exchange of research information. The grade of a particular animal is determined by the apparent …

The following procedure was employed in this investigation. Twelve football players selected from the 1966 freshman and varsity football teams at South Dakota State University were employed as subjects. The subjects had a history of passing the football either on the high school level or during college competition. Two experimental groups were determined and equated from the results of the anterior and posterior muscular strength tests of the throwing arm. …


Isolation Of Anti-Tuberculosis Agent From Korean Soils Containing Decayed Organic Materials, Jong Myong Kim Feb 1967

Isolation Of Anti-Tuberculosis Agent From Korean Soils Containing Decayed Organic Materials, Jong Myong Kim

Electronic Theses and Dissertations

Tuberculosis is still one of the major threats to the health of mankind. Attempts to find suitable chemotherapeutic agents for tuberculosis date almost from the time that Koch (1, 2, 3) announced the discovery of the etiological agent of this disease. The earlier work has been reviewed by Long (3, 18). The modern chemotherapeutic era, however, began when Rich and Follis (3, 29) demonstrated that sulfa-nilamide exerted a light suppressive effect on the course of experimental tuberculosis in guinea pigs. Since that time, numerous investigators (1, 2, 4-14, 16-18, 29, 36, 39, 41-44) have attempted to find chemotherapeutic agents suitable …
