South Dakota Farm Boys Planning Farm And Nonfarm Occupations: A Comparative Analysis, Alan L. Loya
Electronic Theses and Dissertations
Farm youth are finding it increasingly difficult to enter farming as a life occupation, and are therefore faced with a difficult situation when it comes to choosing an occupation. The farm-reared boys must decide whether or not to continue the family tradition in farming, and if they decide not to follow this tradition, they must decide on a nonfarm occupation which they would like to enter. The future welfare of these farm youth is associated with the occupational choices they make at this time. Therefore, a comparison of the characteristics of farm boys who plan farm occupations with those who …

The Retention Of Fallout Particles On Roofs Having Different Slopes, Arden B. Sigl
Electronic Theses and Dissertations
Since World War II the continual buildup and spread of nuclear arms has produced a pressure situation between nations. As more and more nations become nuclear powers and continue to expand their arsenals, the chance of a nuclear attack, either by accident or by specific intent, increases. If a full-scale nuclear attack should develop, the only chance of survival would rest -with a fully prepared population. Even with a fully prepared population many would not survive. The National Fallout Shelter Program is helpful in preventing casualties in the event of a nuclear attack. Studies show, however, that such casualties would …

Reactions Of Oxotrichlorobis(Triphenylphosphine)Rhenium(V), Melvin Leitheiser
Electronic Theses and Dissertations
While sealed tube reactions have been used extensively in the synthesis of other transition metal complexes (1), the method has seen limited use in synthetic rhenium chemistry. The first reaction reported was the preparation of tris (l,1O phenanthroline) rhenium(III) chloride (2). The second reaction was an attempt to isomerize oxotrichlorobis (triphenylphosphine) rhenium(V), ReOCI3-[C65H5) 3P] 2; by refluxing it in chloroform (3). Instead of isomerization, oxodichloro(ethoxy) bis (triphenylphosphine) rhenium(V), ReO(OC2H5 )c12 [C65H5) 3P] was produced; the ethoxy moiety came from an ethanol preservative in commercial chloroform. As temperature was sometimes important, the isomerization was also attempted in chloroform.in a sealed tube …
The Influence Of Anaerobic Pretreatment On The Treatability Of A Milk Waste, Jerry Lee Siegel
The Influence Of Anaerobic Pretreatment On The Treatability Of A Milk Waste, Jerry Lee Siegel
Electronic Theses and Dissertations
Both anaerobic and aerobic treatment of wastewater has been used for many years. Some of the common aerobic treatment systems include oxidation or stabilization ponds, activated sludge, trickling filters, and aerated lagoons. Anaerobic treatment has been most commonly used for digestion of sewage sludge. However, septic tanks, anaerobic lagoons, and anaerobic activated sludge (contact stabilization) units are used to treat wastewater anaerobically. More recently, the two systems have been used in combination, with the anaerobic system preceding the aerobic one. This type of treatment has been used primarily for lagooning of industrial wastes, and most commonly for meat-packing wastes. In …
