In formulating policy toward the Third World, U.S. decisionmakers have been hampered by a superficial understanding of events in developing countries, by a tendency to deal with Third World problems in terms of global considerations, and by the role of the United States as a superpower with responsibility for helping to manage regional security aff
In the third millennium B.C.E., the Oman Peninsula was the site of an important kingdom known in Akkadian texts as "Magan," which traded extensively with the Indus Civilization, southern Iran, the Persian Gulf states, and southern Mesopotamia. Excavations have been carried out in this region since the 1970s, although the majority of studies have focused on mortuary monuments at the expense of settlement archaeology. While domestic structures of the Bronze Age have been found and are the focus of current research at Bat, most settlements dating from the third millennium B.C.E. in Oman and the U.A.E. are defined by the presence of large, circular monuments made of mudbrick or stone that are traditionally called "towers." Whether these so-called towers are defensive, agricultural, political, or ritual structures has long been debated, but very few comprehensive studies of these monuments have been attempted. Between 2007 and 2012, the University of Pennsylvania Museum of Archaeology and Anthropology conducted excavations at the UNESCO World Heritage Site of Bat in the Sultanate of Oman under the direction of the late Gregory L. Possehl. The focus of these years was on the monumental stone towers of the third millennium B.C.E., looking at the when, how, and why of their construction through large-scale excavation, GIS-aided survey, and the application of radiocarbon dates. This has been the most comprehensive study of nonmortuary Bronze Age monuments ever conducted on the Oman Peninsula, and the results provide new insight into the formation and function of these impressive structures that surely formed the social and political nexus of Magan's kingdom.
The Chemistry of Titanium, Zirconium and Hafnium deals with the chemistry of titanium, zirconium, and hafnium and covers topics ranging from the occurrence and metallurgy of all three elements to their nuclear, physical, and chemical properties as well as analytical chemistry. The compounds of titanium, zirconium, and hafnium are also discussed. This volume is comprised of two chapters and opens with a historical overview and discovery of titanium, along with its occurrence and distribution, metallurgical aspects, and nuclear and physicochemical properties. The compounds of titanium are also considered, including alloys and complexes; hydrides and oxides; halides and oxyhalides; titanates and antimonides; and carbides and borides. The second chapter is devoted to zirconium and hafnium, their occurrence and metallurgy; and physical, chemical, and biological properties. Compounds of zirconium and hafnium are described, from alloys and hydrides to zirconates and hafnates; nitrides, phosphides, and arsenides; carbides, silicides, and germanides; molybdates, tungstates, halates, and perchlorates; alkoxides, mercaptides, and dithiocarbamates; and amides, alkylamides, triazenes, phthalocyanines, and bipyridyls. This book will be a valuable source of information for inorganic chemists.
