When the First Edition of this book was written in 1951, the gas turbine was just becoming established as a powerplant for military aircraft. It took another decade before the gas turbine was introduced to civil aircraft, and this market developed so rapidly that the passenger liner was rendered obsolete. Other markets like naval propulsion, pipeline compression and electrical power applications grew steadily. In recent years the gas turbine, in combination with the steam turbine, has played an ever-increasing role in power generation. Despite the rapid advances in both output and efficiency, the basic theory of the gas turbine has remained unchanged. The layout of this new edition is broadly similar to the original, but greatly expanded and updated, comprising an outline of the basic theory, aerodynamic design of individual components, and the prediction of off-design performance. The addition of a chapter devoted to the mechanical design of gas turbines greatly enhances the scope of the book. Descriptions of engine developments and current markets make this book useful to both students and practising engineers.

This book presents a cutting-edge critical analysis of the trope of miscegenation and its biopolitical implications in contemporary Palestinian and Israeli literature, poetry, and discourse. The relationship between nationalism and demographics are examined through the narrative and poetic intrigue of intimacy between Arabs and Jews, drawing from a range of theoretical perspectives, including public sphere theory, orientalism, and critical race studies. Revisiting the controversial Brazilian writer Gilberto Freyre, who championed miscegenation in his revisionary history of Brazil, the book deploys a comparative investigation of Palestinian and Israeli writers' preoccupation with the mixed romance. Author Hella Bloom Cohen offers new interpretations of works by Mahmoud Darwish, A.B. Yehoshua, Orly Castel-Bloom, Nathalie Handal, and Rula Jebreal, among others.

As the Cold War faded, Ambassador Hank Cohen, President George Bush's Assistant Secretary of State for Africa, engaged in aggressive diplomatic intervention in Africa's civil wars. In this revealing book Cohen tells how he and his Africa Bureau team operated in seven countries in crisis - Angola, Ethiopia, Liberia, Mozambique, Rwanda, Somalia and Sudan. He candidly characterizes key personalities and events and provides a treasure trove of lessons learned and basic principles for practitioners of conflict resolution within states.
