The Technology of Discovery Incisive discussions of a critical mission-enabling technology for deep space missions In The Technology of Discovery: Radioisotope Thermoelectric Generators and Thermoelectric Technologies for Space Exploration, distinguished JPL engineer and manager David Woerner delivers an insightful discussion of how radioisotope thermoelectric generators (RTGs) are used in the exploration of space. It also explores their history, function, their market potential, and the governmental forces that drive their production and design. Finally, it presents key technologies incorporated in RTGs and their potential for future missions and design innovation. The author provides a cle...
"This is the third volume of the German Immigrants series (see also Items 6580, 6581, and 6583), this one listing passengers from Bremen to New York between 1863 and September 1867. Owing to the total destruction of the original Bremen passenger lists, this volume, like the others, is the only practical means of discovering information on thousands of individuals for whom immigrant origin data was thought to be irretrievably lost. In effect, it is a partial reconstruction of the Bremen records, based on official passenger lists and manifests in the custody of the National Archives. It is, therefore, a record of arrivals rather than departures, and it is the closest we are ever likely to come to duplicating information in the lost Bremen records"--Publisher website (December 2007).
Since the end of the Cold War, the international community, and the USA in particular, has intervened in a series of civil conflicts around the world. In a number of cases, where actions such as economic sanctions or diplomatic pressures have failed, military interventions have been undertaken. This 1999 book examines four US-sponsored interventions (Panama, Somalia, Haiti and Bosnia), focusing on efforts to reconstruct the state which have followed military action. Such nation-building is vital if conflict is not to recur. In each of the four cases, Karin von Hippel considers the factors which led the USA to intervene, the path of military intervention, and the nation-building efforts which followed. The book seeks to provide a greater understanding of the successes and failures of US policy, to improve strategies for reconstruction, and to provide some insight into the conditions under which intervention and nation-building are likely to succeed.
