My presentation will analyze Adventist College students\u27 views and opinions on Police. Many descriptors will be taken into account, including gender, ethnicity, class standing, major, and religion

The role of St. Paul\u27s Episcopal Church in the 1960\u27s : dealing with racial turmoil

St. Paul\u27s Episcopal Church became involved in a positive manner in the racial turmoil of the 1960 \u27s through the work of its rector from 1956-1985, John H Bonner, Jr., who was influential in keeping Chattanooga relatively peaceful throu·gh the racial problems of this period

The effect of coating architecture and defects on the corrosion behaviour of a PVD multilayer Inconel 625/Cr coating

This paper investigates the effect of substrate surface finish and deposition conditions of PVD multilayer Inconel 625/Cr coatings on their ability to act as a corrosion-barrier. The corrosion-barrier performance of the coatings was characterized by potentiodynamic testing and salt-spray testing followed by image analysis of the exposed surface; further coating properties were investigated through XRD, SEM, EDX and scratch testing. The results show that multilayering produced the expected improvement in scratch resistance however it did not affect corrosion behaviour. Interrupting the deposition process did not decrease the defect density. Defect density was observed to reduce with decreasing substrate surface finish. The corrosion barrier performance of the multilayer Inconel 625/Cr coating (bp100 nm) was greatly improved for coatings deposited on a polished substrate. For the multilayer Inconel 625/Cr coating system used in this work multilayering and process interruption did not prevent defects from limiting the corrosion barrier effectiveness of the coatings. Corrosion barrier performance was successfully enhanced by the use of low roughness substrates to minimise the defect density
