In Rob Neyer's chapter on San Francisco in his Big Book of Baseball Lineups, he speculates that there aren't really good baseball cities, and that attendance more closely correlates with winning percentage than with any other factor. He also suggests that a statistically minded person look at this. I took the challenge and have been playing with a lot of data. This article is available at The C...

Obtaining new materials capable of meeting society’s demands motivates the search for solutions that are satisfying twofold requirements: respect environment and obtaining more durable resistant materials. Cupola slag is a by-product generated in process ductile iron. When undergoes rapid cooling, its vitrification favored, leaving silica an amorphous structure and, thus, susceptible to reactin...

Under clean and green revolution programme, an urgent need has been felt to develop mitigation devices and pollution control instruments. Through this paper, discussion has been made on pollution thrust emanating in atmosphere from stacks and its control through indigenous technology and control instruments developed in India to meet the techno-economical needs of country. Main emphasis has bee...

Samples of aluminosilicate refractory after operation in the shaft and hearth a coke-gas cupola were investigated; this was used for smelting cast iron with spheroidal graphite using carbon wastes from aluminium electrolysis production as reducing agent. Use only fluorine-containing solid fuel allows to utilize hazardous man-caused wastes, improves economic performance has influence on resistan...

For the prototypical Ge/Si(001) system, we show that at high growth temperature a new type of Stranski-Krastanow islands is formed with side facets steeper than {111} and high aspect ratio. Nano-goniometric analysis of the island shapes reveals the presence of six new facet groups in addition to those previously found for dome or barn-shaped islands. Due to the highly multi-faceted island shape...
