Interactions Of Rhenium(V) Chloride And Oxotrichlorobis(Triphenlyphosphine)Rhenium(V) With Selected Solvents, Paul Luther Holm
Interactions Of Rhenium(V) Chloride And Oxotrichlorobis(Triphenlyphosphine)Rhenium(V) With Selected Solvents, Paul Luther Holm
Electronic Theses and Dissertations
The purpose of this study was to examine the solution interactions of rhenium(V) chloride and oxotrichlorobis(triphenylphosphine)rhenium(V) in a continuation of studies of rhenium(V) chemistry. These goals were accomplished using vacuum line and Schlenk tube techniques. As a result of this work, rhenium(V) chloride was found to dissolve with reaction in 1, 4-dioxane, diethyl ether and acetone. There was only a very small amount of rhenium(V) chloride which dissolved in carbon tetrachloride, chloroform and cyclohexane. Part of what did dissolve was shown by electronic and infrared spectroscopy to be oxotetrachlororhenium(VI) which was present as an impurity in small amounts. Oxotetrachlororhenium(VI) reacts …
Prices, Wages, And Causality, Marshall Ugo Constantino
Prices, Wages, And Causality, Marshall Ugo Constantino
Electronic Theses and Dissertations
This study is an attempt to examine the hypothesis of unidirectional causality between wages and prices. That is, do wage movements depend solely on price movements, or is there "feedback" from wages to prices endogenous to the price wage relationship? Do price movements depend solely on wage movements or does "feedback" from prices to wages exist? In addition, an attempt to provide some insight into the controversy created by the use of spectral methods to determine lead-lag relationships in time series data is made.
A Rotating Elliptical Cutting Device For A Forage Harvester, John Richard Durfee
A Rotating Elliptical Cutting Device For A Forage Harvester, John Richard Durfee
Electronic Theses and Dissertations
Many variables have to be taken into consideration, along with design criteria, if a plant stem cutter is to perform satisfactorily. Some plant characteristics which affect the energy required to cut plant stems are: (a) moisture content of the plant, (b) maturity of the plant, and (c) the plant variety. Some important mechanical variables for the design engineer include: (a) clearance between the cutting blade and the stationary edge, (b) the sharpness of the cutting blade, and (c) the width of cut. The design and subsequent performance of an elliptical cutter would be dependent upon these variables and operating variables …

Effects Of Self-Hypnosis Training Sessions On Pre-Competition Anxiety Levels Of Collegiate Wrestlers, Michael Ernest Engels
Effects Of Self-Hypnosis Training Sessions On Pre-Competition Anxiety Levels Of Collegiate Wrestlers, Michael Ernest Engels
Electronic Theses and Dissertations
Members of the athletic coaching profession have long been concerned with obtaining the maximum physical and mental performance from their athletes. This concern has been evidenced through the many studies that have been completed involving methods of enhancing motor performance. Research finding from these studies have influenced changes in training programs and ways of preparing for athletic competition, but these changes have been concerned with primarily with physical development. Although being ready physically is very important for maximum performance, it is not the only factor to be considered. Mental conditioning also plays an important role in the success of any …
Computer Simulation Model Of The Immune Response Of Mice To Western Equine Encephalitis (Wee) Computer Simulation Model Of The Immune Response Of Mice To Western Equine Encephalitis (Wee) Virusirus, Gilbert Chi Kuna Ho
Electronic Theses and Dissertations
The lymphatic system of an animal is optimally developed to protect the body from antigenic invasion. The epithelial and subepithelial compartments of the body are provided with a vast number of wandering cells and a network of centralized lymphorecticular tissues. All of these are capable of reacting to intruding foreign antigens. Upon antigentic challenge, immunocompetent cells (ICC) or antigen specific lymphocytes are activated; this leads either to cell mediated and/or humoral antibody immune responses. The subsequent effect is an accumulation of the responding cells, both by local proliferation and recruitment from the circulation. Through the interaction of both cellular and …
Nucleophilic Substitution At Phosphorus: Phosphate Thioesters, Ronnie L. Wilde
Nucleophilic Substitution At Phosphorus: Phosphate Thioesters, Ronnie L. Wilde
Electronic Theses and Dissertations
It was my objective to try to determine the mechanism of nucleophilic substitution at phosphorus in monothiophosphate triesters and to apply what I learn to the other phosphate systems. I also tried to obtain more data to show that the Lewis acid-base type complex through the phosphoryl oxygen is existent and does influence the reaction.
Breeding Waterfowl Populations In South Dakota, Wayne G. Brewster
Breeding Waterfowl Populations In South Dakota, Wayne G. Brewster
Electronic Theses and Dissertations
Breeding waterfowl in South Dakota were censused on 500 legal quarter sections within 125 clusters representing a proportional stratified random sample of 0.16 percent of the state area. Two breeding pair counts, one in May and second in June, were conducted each year on the sample units in 1973 and 1974. Densities of total breeding pairs averaged 5.58 and 2.30 pairs per km2 in 1973 and 1974, respectively. Estimated populations based upon these densities were 1,067,500 breeding pairs in 1973 and 439,600 breeding pairs in 1974. The 58.8 percent decrease in the population occurred concurrently with intensification of drought conditions …
Food Habits, Growth, And Production Of Young-Of-The-Year Walleyes, Stizostedion Vitreum Vitreum (Mitchell), In A South Dakota Pond, Ronne E. Walker
Food Habits, Growth, And Production Of Young-Of-The-Year Walleyes, Stizostedion Vitreum Vitreum (Mitchell), In A South Dakota Pond, Ronne E. Walker
Electronic Theses and Dissertations
A 12.45 hectare South Dakota pond was stocked with 25,000 walleye, Stizostedion vitreum vitreum (Mitichell), fingerling on 13 June, 1973. Walleyes were monitored for growth rate and food habits until 13 September, 1973. Walleyes were removed from the pond using various methods in order to evaluate the efficiency of removal methods. The average total length and average weight of walleyes in the pond increased from 43.5 mm and 0.50 g on 13 June to 167.1 mm and 41.25 g on 13 September. This was a gain of 123. 6 mm and 40.75 g or an average daily increase of 1.34 …

The Development Of Validated Metric Teaching Materials: Basics, Barbara Vanhove Hoff
The Development Of Validated Metric Teaching Materials: Basics, Barbara Vanhove Hoff
Electronic Theses and Dissertations
The purpose of this study was to develop a “Basic Metric” self-instructional programs for use by female adult consumers who wish to learn to use the metric measurements. Such a study was not conceived as an experimental or descriptive type of research but rather as a creative project in which innovative teaching materials are developed. Although the creative element is of major importance, the use of programming required a scientific procedure for developing the teaching materials. The sequence of steps in programming is similar to the steps advocated by systems designers. Field testing of teaching materials was a second purpose. …
