The use of coal is required to help satisfy the world's energy needs. Yet coal is a difficult fossil fuel to consume efficiently and cleanly. We believe that its clean and efficient use can be increased through improved technology based on a thorough understanding of fundamental physical and chemical processes that occur during consumption. The principal objective of this book is to provide a current summary of this technology. The past technology for describing and analyzing coal furnaces and combus tors has relied largely on empirical inputs for the complex flow and chemical reactions that...

This regional study looks at the topography and epigraphy of Megaris, the territory between Attica, Corinth and Boetia, focusing on the Post-Classical periods. Philip Smith examines in turn, the archaeological, literary and epigraphic evidence for the region, compiling a useful catalogue of sites on the Megarid, with numerous maps and plans. All inscriptions cited are included in an appendix. In conclusion Smith posits an unusually stable transition between Classical and Hellenistic, with the region possibly even witnessing economic growth. From the epigraphic evidence observations are made...
