The Synthesis And Characterization Of Several Copper (Ii) Complexes Of Quinuclidinone-Containing Ligands. Possible Models For Type I Copper Blue Proteins., Victor Thomas Wilcox

Masters Theses

Several copper (II) complexes with bidentate quinuclidinone containing ligands have been synthesized and characterized. These complexes appear to be possible models for the type I copper (II) in the copper "blue" proteins. The spectral and magnetic properties indicate that the complexes have a pseudo tetrahedral microsymrnetry about the central metal ion. The complexes contain chromophores of the following forms: CuN₄, CuN₂O₂, and CuN₂x₂, where X is either Cl or Br. While the spectra of these complexes lack the intense 17,000 cm^-1 band typical of copper "blue" proteins, the optical …

Disk And Strip Forging With Side Surface Foldower: Part 2: Evaluation Of The Upper-Bound Solutions, Ronald A. Kohser, B. Avitzur

Materials Science and Engineering Faculty Research & Creative Works

The upper-bound solutions developed in Part 1 are evaluated with regard to their ability to produce a lower value for required power (load, pressure, or work). Comparisons made with existing solutions such as the triangular field solution and one-zone bulge solution show that for strip, each solution has a domain of geometry and friction in which it is superior. The new solution produces a lower upper-bound for conditions of high interface, friction and relatively thin specimen, the area where fold over is the observed mode of flow. For solid cylindrical disks, the solution fails to improve upon existing analyses, but …

Some Results On Inferences For The Gamma And Double Exponential Distributions, John Victor Grice

Doctoral Dissertations

"This dissertation is presented in publication form and consists of two articles. The first article considers testing the mean of a gamma distribution. For the case that both parameters in the ganuna distribution are unknown, approximate tests for the mean are derived and tables are provided for their implementation. The power of the tests are compared to the power of the uniformly most powerful tests on the mean when the shape parameter is known. In addition, some limiting results are derived. The second article compares conditional and unconditional methods of constructing confidence intervals for the location parameter in the two-parameter …

Landsat Image Analysis Of Linears And Lineaments In The Tri-State District, Missouri-Oklahoma-Kansas, Solomon Hartley Toweh

Masters Theses

"Lineations within the Tri-State mining district are classified as megalineaments, lineaments and linears, based on length. One megalineament, 120 lineaments and 205 linears are identified on the LANDSAT imagery. In order of importance a dominant northeast set, northwest set, north-south set and east-west set are recognized. These range from 0.8 miles (1.3 km) to 68 miles (109.4 km) in length.

Major lineation trends spatially relate with trends of mined areas In the Picher field both northeast and northwest lineations generally parallel mined areas. In the Galena field ore and lineations trend northeast while in the Joplin and Duenweg-Webb City-Oronogo field …

Sedimentology Of The Hannibal Formation In Northeastern Missouri And Western Illinois, Michael Harry Deming

Masters Theses

"The Hannibal Formation (Kinderhookian) occurring in northeastern Missouri and western Illinois is a fine-grained, terrigenous, sedimentary unit which can be divided into an upper and a lower portion, based on lithology. The upper portion consists of alternating coarse and argillaceous, fine siltstone units, while the lower portion consists of a silty mudstone with an occasional thin siltstone unit. At the extreme western margin of the formation, near where the Hannibal almost pinches out, the formation consists entirely of a silty claystone. Extending southward along the study area, the coarse siltstone units of the upper Hannibal become thinner, and eventually pinch …

Measurement Of Poisson's Ratio And Tangent Modulus Of A Loess, Craig Randall Bowers

Masters Theses

"A series of triaxial tests are used to develop mathematical models for tangent modulus and Poisson's ratio for a remolded loessial soil. These two models are then utilized in a finite element computer program to model the behavior of a shallow foundation placed on compacted loess. Different models for Poisson's ratio gave widely varying load settlement curves, however a constant value of .32 gave results very similar to that given by the experimentally developed model. It was found that the model developed for tangent modulus yielded unreasonable results when utilized in the finite element analysis until a limiting value was …
