Sporological Evidence On The Geological Age Of The Dunkard Strata In The Appalachian Basin., John Albert Clendening
Sporological Evidence On The Geological Age Of The Dunkard Strata In The Appalachian Basin., John Albert Clendening
Graduate Theses, Dissertations, and Problem Reports (ETD)
The primary purpose of the present study has been to establish palynological evidence on the geological age of the Dunkard strata, a subject of debate for at least 90 years. During this time the popular inclination has been to accept the age as Permian without serious question. The present study of fossil spores and pollen substantiates an Upper Pennsylvanian rather than a Permian age for the entire sequence of strata called the Dunkard Group.

Algebraic Models In Particle Physics., Elmer Douglas Dickens
Algebraic Models In Particle Physics., Elmer Douglas Dickens
Graduate Theses, Dissertations, and Problem Reports (ETD)
The problem of the mass spectrum of mesons is considered from the oint of view of algebraic models based on the Lie algebras of non-compact groups. After describing the group-theoretical approach to particle physics and difficulties encountered in applying it to the mass spectrum problems, especially the O'Raifeartaigh-Segal-Jost theorems, we consider the class of algebraic models recently set forth by A. Bohm. These models emply the Lie algebras of certain, physically interesting Lie groups, but go outside the Lie algebraic structure by allowing non-Lie algebraic "coupling" terms. The resulting associative algebraic models can be given a rigorous foundation as an …
The Strength And Stiffness Of Steel Deck Subjected To In-Plane Loading., Duane Scott Ellifritt
The Strength And Stiffness Of Steel Deck Subjected To In-Plane Loading., Duane Scott Ellifritt
Graduate Theses, Dissertations, and Problem Reports (ETD)
Steel deck is widely used in the floors and roofs of steel framed structures to support gravity loads. In addition, it can effectively resist in-plane shear loading when properly connected to a structural steel framework and can help to brace a building against lateral forces. This feature of steel deck floors and roofs has long been recognized but, with few exceptions, designers have not been able to take advantage of it because design formulas have not been available. This investigation was undertaken for the purpose of evaluating the performance of wide, narrow, and intermediate rib decks when used as shear-resistant …

Graduate Theses, Dissertations, and Problem Reports (ETD)
Organized in March 1936 at a convention in Buffalo, New York, the Nazi-inspired German American Bund began its short and stormy existence by seeking to unite the entire German American community under its direction. The Bund had been preceded by numerous Nazi splinter groups and an organization known as the Friends of the New Germany. The chief distinction between the Bund and its predecessors was the requirement that only American citizens could hold leadership positions in the organization. The Bund also tried to be more circumspect in its relations with Nazi agencies in Germany. In its effort to unite the …

Alkylation Of Nitroaromatic Compounds With Sulfur Ylids., Gregorio Cruz Pedroza
Graduate Theses, Dissertations, and Problem Reports (ETD)
In a study with variation of the ylid-nitrobenzene ratio and subsequent treatment with air, the optimum reaction conditions for the methylation of nitrobenzene with dimethyloxosulfonium ylid were found to be an 8-fold molar excess of methylid over nitrobenzene, and initial reaction for 15 minutes in an atmosphere of nitrogen, followed IX by passing air through the reaction mixture for 5 hours prior to work-up. With these experimental conditions the nitrotoluene yield was increased from 17$ to 40–50$, dialkylation was observed, and essentially no nitrobenzene was recovered.

Sensitivity Analysis In Optimum Process Design, Tai Ming Chang
Sensitivity Analysis In Optimum Process Design, Tai Ming Chang
Graduate Theses, Dissertations, and Problem Reports (ETD)
The effects of parameter variation and uncertainty on optimal process design have been studied. Equations necessary for determining the sensitivity of optimal system performance to parameter variation are derived. Design criteria have been developed for optimal design of systems that are either sensitive to parameter variation or involving parameter uncertainty. The sensitivity equations for systems described by algebraic, differential, and difference equations are derived based on the Lagrange multiplier method, Pontryagin's maximum principle, and the discrete version of the maximum principle, respectively. Such sensitivity equations are linear and can be solved for sensitivity coefficients. Two methods are proposed for optimal …
