Chemical Bonding In Niobium Heptaflouride, Russell Leroy Wilson
Chemical Bonding In Niobium Heptaflouride, Russell Leroy Wilson
Electronic Theses and Dissertations
Heptacovalent bonding, in which seven atoms are bonded to a central atom, is known for substances whose structures conform to three different symmetry types. The IF_7 molecule has pentagonal bypyramidal symmetry; the ZrF_7^(--) ion has the structure of a distorted octahedron; NbF_7^(--) and TaF_7^(--) both have distorted trigonal prism symmetry. An investigation of NbF_7^(--) is reported here; the theory of direct-valence bonding is used to determine the approximate bond strengths and bond angles for the ion. The direct valence method is one of two widely used methods of studying chemical structures, the other being the molecular orbital method. These methods …

Effect Of Slope And Exchangeable Sodium On Run-Off, Erosion And Electrical Conductivities Of Leachates From Cheyenne Sandy Loam Soil, Abbas Shahrzad Tabatabai
Electronic Theses and Dissertations
The textbooks of soil science, discussing the effect of degree of slope on surface run-off and erosion, mention that the lowest amount of run-off occurs at (0) slope. As the degree of slope increases, the amount of surface run-off and erosion also increases. Different experiments report that an increase in the degree of slope is accompanied by an increase in surface run-off and erosion. However, in one experiment, Duley and Kelly (2) report that the degree of slope has only a slight effect on infiltration of water. Several experiments have been done on the effect of exchangeable sodium on the …

This can be accomplished by using a vacuum tube device. The theoretical analysis of the nonlinear characteristic of the electronic circuit will constitute the main part of the work. The complete control system consisted of a feedback type oscillator, a power …
The Dielectric Properties Of Mixtures Of Organic Compounds And Perfluoropropane, Vei-Shi Chen Ho
The Dielectric Properties Of Mixtures Of Organic Compounds And Perfluoropropane, Vei-Shi Chen Ho
Electronic Theses and Dissertations
In this study, an attempt was made to understand the type and amounts of metastable intermediates formed when perfluoropropane was placed under electrical stress by adding small amoutns of organic compounds such as thiophene, isopropyl mercaptan, ethyl methyl sulfide, dimethyl disulfide, carbon disulfide, and nitrobenzene. The sulfur compounds were chose because fluorine was reported to react with thiophene to form sulfur hexafluoride. It was thought that if fluorine were formed from perfluorocarbons in the corona, it might be advantageous to remove this metastable species. Nitrobenzene was used because of its known free radical inhibitor characteristic in polymerization reactions. The hope …

The Design And Development Of An Automatic Guiding System For A Tractor, Ali A. Hamidi
Electronic Theses and Dissertations
Mechanization and Automation are very fashionable words in present day Agriculture. Both imply a reduction in the amount of human effort necessary to achieve certain ends, and to accept the need for either of them is to assume that it will lead to some financial gain. Automation as applied to Agriculture is to improve many limited factors which affect the final yield of any agricultural crop. One of these factors, the mechanical operation, requires considerable care and attention to more nearly insure maximum yield and high quality. Numerous methods have been adopted through research and development to minimize field losses …

The Effect Of A Weight Training Program Upon Strength And Trunk Flexibility Of Football Players At South Dakota State College, David H. Greenwood
Electronic Theses and Dissertations
In the past several years, the use of progressive resistance exercises has increased to the point where it is widely accepted as one of the best methods of increasing strength. The popularization of such exercises has brought about the establishment of weight training programs by football coaches for the purpose of increasing strength between seasons. To effectively increase strength through such exercises, proper methods must be maintained. The use of improper methods of exercise may result in an increase in endurance, where an increase in strength is desired. Weight training is an ideal form of exercise for the development of …

A Comparison Of Reaction Times To A Kinesthetic And A Tactual Stimulus For Groups Of Athletes And Non-Athletes, Ronald J. O'Brien
Electronic Theses and Dissertations
Research in the prediction of athletic ability has for some years been of major interest in the minds of athletic coaches. This has been particularly true in the field of reaction-time studies. Movement and reaction to tactual stimuli are important attributes of the good athlete, and reaction time to various stimuli, such as visual, tactual, and auditory, have been used as a basis of prediction. This research attempted to study reaction-time measures to muscle sense by use of tactual and kinesthetic stimuli. This study compared reaction time to kinesthetic and tactual stimuli of athletes to that of non-athletes. It was …
A Study Of Selected Factors Which May Be Associated With The Imminent Migration Of Individuals From The Lower Brule Indian Reservation, Frank C. Estes
A Study Of Selected Factors Which May Be Associated With The Imminent Migration Of Individuals From The Lower Brule Indian Reservation, Frank C. Estes
Electronic Theses and Dissertations
Pages of history are filled with the recording of man’s movement from an area of lesser opportunity to one with a more favorable environment for security and happiness. The Dakota people too were lured toward “greener pastures” like countless ages of people have been. However, the needy migrant (particularly the Indian) in American life may well find himself a virtual outcast, not only from his own parent group for forsaking his “gemeinschaft” affiliations, but because the migrant is not yet a legally-qualified resident of the new community. In spite of the unforeseeable shortcomings which any migrant may encounter, however, migration …
Cuboctahedral And Icosahedral Bonding, Jack Rhoades Canon
Cuboctahedral And Icosahedral Bonding, Jack Rhoades Canon
Electronic Theses and Dissertations
Before quantum mechanics was developed, the theory of chemical bonding was generally discussed only qualitatively. Since then, however, several theories based on quantitative studies have been advanced. Even the use of quantum mechanics makes it possible to get exact results for only the simplest problems. Nevertheless quantitative results can be obtained for the n-boby problem by using approximation methods. The use of group theory in chemical bonding, first proposed by Bethe, simplified the problem a great deal. This allows one to take advantage of the symmetry properties of a molecule or ion in determining the bonding waves functions and energy …
The Effect Of A Progressive Resistance And Flexibility Exercise Program On Free Running Speed, Ronald D. Campbell
The Effect Of A Progressive Resistance And Flexibility Exercise Program On Free Running Speed, Ronald D. Campbell
Electronic Theses and Dissertations
The speed of an athlete has always been of great importance to the athletic coach and suggested methods of improving speed have resulted in many studies in research. In 1957, Meisel found that even though an 18 session progressive resistance program did increase leg strength, it significantly reduced the free running speed. This was contrary to results of previous research which indicated increased leg strength did improve running speed. There exists the theory that the stronger the legs, the more capable the runner of overcoming the resistance of body weight and therefore the whole body should be propelled at a …
Some Life History And Ecological Activites Of The Richardson Ground Squirrel In South Dakota, Dean Robert Gunderson
Some Life History And Ecological Activites Of The Richardson Ground Squirrel In South Dakota, Dean Robert Gunderson
Electronic Theses and Dissertations
Whenever man has gone he has changed his environment to suit his needs. Because of his need for food, man has plowed up the prairies and converted the grasslands to grain fields. Before white man settled the Great Plains, range rodents such as the prairie dog and the ground squirrel existed undisturbed and unmolested except by their natural predators. With the advent of cultivated crops, the range herbivores found a new and tasty source of food. Among these primary consumers which took advantage of man’s interference with the natural prairie was the Richardson ground squirrel, Citellus richardsoni (Figure 1). During …

Preliminary Results On The Hooded Ogee Pipe Drop Spillway, Donald Mervin Edwards
Electronic Theses and Dissertations
The farm pond has come into popular use in the past few years as an inexpensive source of water for livestock, irrigation, and domestic use. With minor design modifications, the farm pond can be used as a flood detention structure. Component parts of a farm pond are the storage area, earth damn, grassed emergency flood spillway, and mechanical spillway. The mechanical spillway is probably the most important component part of safeguarding the successful operation of the farm pond due to its primary purpose of carrying low flows of surplus watershed runoff through the earth damn. There are three characteristics that …

An Evaluation Of Land Policies, State And Federal In South Dakota Since The Homestead Act, And Application Of The Experience To Iran, Nosratollah Cyrus Khatibi
Electronic Theses and Dissertations
The formulation of land policies of the United States has been a gradual and continuous process. Land policies were built upon the experiences of the past and goals for the future. The physical characteristics of the land and the cultural characteristics of its owners and operators greatly affected the outcome of land programs designed to carry out policy. An evaluation of land policies, present and past, is not undertaken without examining the social, political, and economic conditions prevailing when the policies were formulated. Such an examination for the United States indicated changes in the concepts of property and tenure, and …
A Comparative Analysis Of Performance Of College Women On The Kraus-Weber Test And The Aahper Test, Sharon Ann Mundt
A Comparative Analysis Of Performance Of College Women On The Kraus-Weber Test And The Aahper Test, Sharon Ann Mundt
Electronic Theses and Dissertations
America has become more cognizant of the need for physical fitness through the Kraus-Weber Test of Minimum Muscular Fitness and the Youth Fitness Program instigated by President Eisenhower in 1956. The low level of physical fitness in the United States has been attributed largely to the high degree of mechanization. Labor saving devices have decreased the natural physical activity, leading to little physical stamina development by day to day living. The rapidly changing mode of American living has left its imprint on the physical fitness of American youth. The purpose of this study was to compare and analyze the Kraus-Weber …

Fall Food Habits Of The Merriams' Wild Turkey In Western South Dakota, Curtis Martin Twedt
Electronic Theses and Dissertations
The several varieties of wild turkey (Meleagris gallopavo) formerly ranged over much of what is now eastern, central and southwestern United States. A large portion of the species habitat was destroyed by logging and by clearing forest land for agricultural use. Wild turkey population, were also directly decimated because of bunting by early settlers. Edminister (1954) estimated present Wild turkey range to be approximately 1 per cent of the historic range. In the past few decades, wild turkey population have increased to the point where the species has begun to assume a prominent place among the game birds. . . …
