This volume explores the part played by different metals in use from the fourth millennium BC to the Early Iron Age, not only in the Aegean but also in the wider Old World. It addresses the divergent uses and roles of different metals, the interrelationships of these roles and the changing values that may have been accorded to them at different times and in different places by producers and consumers. Individually, the papers in the volume contemplate the particular properties of different metals and the various issues concerning their frequent under-representation in the archaeological (but not necessarily textual) record, and also point out comparative and diachronic perspectives that may have the ability to offer insights into their important roles in wider cultural and historical changes over a period of several millennia. After the Introduction and Chapter 1, which reflects on some of the parameters involved in the term ‘precious’ as applied to metals, the remaining six chapters cover the Aegean and the networks that link the Aegean with Italy, Cyprus and the Near East more generally, and south-east Anatolia and the Caucasus. Between them they discuss the beginnings of regular iron metallurgy, the uses of and attitudes to gold, silver and bronze and other copper-based alloys at various times between the fourth millennium BC and the Early Iron Age.

Essential reading for experts in the field of RF circuit design and engineers needing a good reference. This book provides complete design procedures for multiple-pole Butterworth, Chebyshev, and Bessel filters. It also covers capacitors, inductors, and other components with their behavior at RF frequencies discussed in detail. *Provides complete design procedures for multiple-pole Butterworth, Chebyshev, and Bessel filters *Covers capacitors, inductors, and other components with their behavior at RF frequencies discussed in detail

As the biomedical engineering field expands throughout the world, clinical engineers play an ever more important role as the translator between the worlds of the medical, engineering, and business professionals. They influence procedure and policy at research facilities, universities and private and government agencies including the Food and Drug Administration and the World Health Organization. Clinical engineers were key players in calming the hysteria over electrical safety in the 1970s and Y2K at the turn of the century and continue to work for medical safety. This title brings together all the important aspects of Clinical Engineering. It provides the reader with prospects for the future of clinical engineering as well as guidelines and standards for best practice around the world.
