This book presents a state-of-the-art analysis of energy efficiency as applied to mining processes. From ground fragmentation to mineral processing and extractive metallurgy, experts discuss the current state of knowledge and the nagging questions that call for further research. It offers an excellent resource for all mine managers and engineers who want to improve energy efficiency to boost both production efficiency and sustainability. It will also benefit graduate students and experienced researchers looking for a comprehensive review of the current state of knowledge concerning energy efficiency in the minerals industry.

Extending deconstructive theory to historical and political analysis, Timothy Mitchell examines the peculiarity of Western conceptions of order and truth through a re-reading of Europe's colonial encounter with nineteenth-century Egypt.

For more than thirty years, humankind has known how to grow enough food to end chronic hunger worldwide. Yet while the ''Green Revolution'' succeeded in South America and Asia, it never got to Africa. More than 9 million people every year die of hunger, malnutrition, and related diseases every year - most of them in Africa and most of them children. More die of hunger in Africa than from AIDS and malaria combined. Now, an impending global food crisis threatens to make things worse. In the west we think of famine as a natural disaster, brought about by drought; or as the legacy of brutal dictators. But in this powerful investigative narrative, Thurow & Kilman show exactly how, in the past few decades, American, British, and European policies conspired to keep Africa hungry and unable to feed itself. As a new generation of activists work to keep famine from spreading, Enough is essential reading on a humanitarian issue of utmost urgency.
