The Yehud Coinage
This volume presents a die study of the provincial silver coinage of Judah in the late Persian, Macedonian, and early Hellenistic periods. It offers correct descriptions of the coins, their designs, and their inscriptions; enumerates the obverse and reverse dies identified for each of the 44 recorded types; and explains the probable sequence of the issues as deduced from iconographic associations and die links. The iconography of the coin types is examined in depth, with comparisons to motifs in Greek, Persian, and ancient Near Eastern art, including other local coinages and sources in Judahite material culture. The monograph also analyzes data relating to the metrology, metal content, and circulation of the coinage. Overall, the study attempts to place the Yehud coinage in its historical context and to define its role in the economy of the ancient province of Judah.
America's Achilles' Heel
Nuclear, biological, and chemical (NBC) weapons delivered covertly by terrorists or hostile governments pose a significant and growing threat to the United States and other countries. Although the threat of NBC attack is widely recognized as a central national security issue, most analysts have assumed that the primary danger is military use by states in war, with traditional military means of delivery. The threat of covert attack has been imprudently neglected.Covert attack is hard to deter or prevent, and NBC weapons suitable for covert attack are available to a growing range of states and groups hostile to the United States. At the same time, constraints on their use appear to be eroding....

Pulse Detonation Engine
What Is Pulse Detonation Engine A pulse detonation engine (PDE) is a type of propulsion system that uses detonation waves to combust the fuel and oxidizer mixture. The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave and the next. Theoretically, a PDE can operate from subsonic up to a hypersonic flight speed of roughly Mach 5. An ideal PDE design can have a thermodynamic efficiency higher than other designs like turbojets and turbofans because a detonation wave rapidly compresses the mixture and adds heat at constant volume. Consequently, moving parts like compressor spools are not necessarily required in the engine, which could sign...
Daily Life in Biblical Times
While the history of Israel during the period from ca. 1200 to 586 B.C.E. has been in the forefront of biblical research, little attention has been given to questions of daily life. Where did the Israelites live? What did people do for a living? What did they eat and what affected their health? How did the family function? These and similar questions form the basis for this book. The book introduces different aspects of daily life. It describes the natural setting and the people who occupied the land. It deals with the economy, both rural and urban, emphasizing the main sources of livelihood such as agriculture, herding, and trade. These topics are discussed in relation to the family in part...
Safety Issues Associated with Plutonium Involvement in the Nuclear Fuel Cycle
The "VOLGA" conferences, hosted in odd-numbered years by the Department of Theoretical and Experimental Reactor Physics of the Moscow Engineering Physics Institute (MEPhI), are some of the most prestigious technical meetings held in Russia. Traditionally, these conferences present the opportunity for reactor physicists from around the world to gather at MEPhI's holiday camp on the banks of the Volga river (near Tver) to exchange ideas and explore innovative concepts related to nuclear power development. In 1997, NATO became involved in the "VOLGA" meetings for the first time by co-sponsoring "VOLGA97" as an advanced research workshop. This workshop broke with tradition a bit in that the venu...
