The Effects Of Interstage Backmixing On The Design Of A Multicomponent Distillation Column, Gary D. Loud, Raymond C. Waggoner
The Effects Of Interstage Backmixing On The Design Of A Multicomponent Distillation Column, Gary D. Loud, Raymond C. Waggoner
Chemical and Biochemical Engineering Faculty Research & Creative Works
Interstage back mixing is encountered as entrainment in many distillation columns. Bidirectional back mixing is common in liquid-liquid extraction. These effects, which reduce the effectiveness of a separation process, may interfere with its operation even to the extent of shutdown. The design engineer and process operator need to recognize the effects of back mixing and must quantify them to take effective countermeasures. A procedure is developed which describes the effects of interstage bidirectional back mixing in multistage separations. It is implemented on an existing simulation for multicomponent distillation and is used to show the effect of back mixing on product …

Measurements have been made of the short-range spin correlations in USb, a metallic compound that orders antiferromagnetically. The system has no transverse fluctuations, and the longitudinal spin correlations are anisotropic, showing stronger interactions within the ferromagnetic sheets than between them. The results of this and other experiments can be understood with simple concepts involving the bonding of 5f electrons. © 1978 The American Physical Society.

A drift-tube-mass-spectrometer apparatus has been used to study the production of Cl-·HCl cluster molecules in HCl-N2 mixtures. The concentration of HCl was 730 ppm and the total pressure ranged from 0.1-5 Torr. The primary ion Cl- is produced mainly by dissociative attachment of HCl and is converted to a cluster ion in a three-body collision. The rate of formation of the cluster ion is k2≃ 10-25 cm6/sec at E/N=12 Td. © 1978 American Institute of Physics.

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 …

Solar-Cell Design Based On A Distributed Diode Analysis, Jack L. Boone, Thomas P. Van Doren
Solar-Cell Design Based On A Distributed Diode Analysis, Jack L. Boone, Thomas P. Van Doren
Electrical and Computer Engineering Faculty Research & Creative Works
The front surface of a p-n junction solar cell has resistive losses associated with the diffused layer, the metal-semiconductor contact, and the grid structure. These losses are analyzed by considering the spatially distributed nature of the p-n junction and the grid conductors. This distributed diode analysis is especially useful for solar cells operated under concentrated sunlight conditions. The results show the dependence of the V-I characteristics and the maximum power output per unit cell on the ratio of the diffused layer resistance to the junction dynamic resistance. This ratio can assist the designer in establishing proper grid structure geometries and …

The Synthesis And Characterization Of Several Copper (Ii) Complexes Of Quinuclidinone-Containing Ligands. Possible Models For Type I Copper Blue Proteins., Victor Thomas Wilcox
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 …
Sedimentology Of The Hannibal Formation In Northeastern Missouri And Western Illinois, Michael Harry Deming
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 …

A Hydrologic Analysis Of The Meramec River Basin, Missouri, Glendon Taylor Stevens Iii
Masters Theses
"The purpose of this study was to develop water budgets for the Meramec River Basin. These budgets, developed from average annual data, are quantitative assessments of the basin's water resources.
On a long-term basis, inflow was approximately balanced by outflow indicating that the system is steady state.
Precipitation was found to be the only substantial source of inflow to the basin and averages about 40 inches per year.
Evapotranspiration was found to be the major source of outflow from the basin. Annually it accounts for about three quarters of the total outflow and averages about 30 inches.
Streamflow was found …

An X-Ray Diffraction Analysis Of The Lacro₃-Laalo₃ Solid Solution Series, Robin Ashley Murphy
Masters Theses
"A crystallographic study was made of powders from the LaCr1-x AlxO₃, La.90(Mg.05 Cr1-x Alx ).95O2.83 , and La1±xCrO₃ systems. The relationships between composition and thermal expansion, electrical conductivity, and vaporization were also investigated. The x-ray diffraction data of the LaCrCO₃ - LaAlO₃ compounds showed the system to form a single phase solid solution for any given sample from the series. The orthorhombic to rhombohedral phase transition was depressed to below room temperature at approximately 13% Al+3 substitution"--Abstract, page ii.
