The proceedings of STAIF-2007 feature a broad spectrum of topics on. These topics span the range from basic research to the most recent technology advances and hardware development and testing. The proceedings will be of particular interest to program managers, practicing engineers, academicians, graduate students, system designers, and researchers interested in the fields of space technology and space science.

As the British, French and Spanish Atlantic empires were torn apart in the Age of Revolution, Portugal steadily pursued reforms to tie its American, African and European territories more closely together. Eventually, after a period of revival and prosperity, the Luso-Brazilian world also succumbed to revolution, which ultimately resulted in Brazil's independence from Portugal. The first of its kind in the English language to examine the Portuguese Atlantic World in the period from 1750 to 1850, this book reveals that despite formal separation, the links and relationships that survived the demise of empire entwined the historical trajectories of Portugal and Brazil even more deeply. From constitutionalism to economic policy to the problem of slavery, Portuguese and Brazilian statesmen and political writers laboured under the long shadow of empire as they sought to begin anew and forge stable post-imperial orders on both sides of the Atlantic.

3rd Symposium on Space Colonization. 2nd Symposium on New Frontiers and Future Concepts, Albuquerque, New Mexico, 13-17 February 2005

The proceedings document the opportunities for space science onboard the international space station (ISS), currently under construction by an international consortium. These proceedings include the latest on the construction of and payload operations on the ISS; human physiology in space; fundamental physics; engineering research and technology development; thermal control technologies for future spacecraft; propulsion technology for interstellar precursor missions; breakthrough propulsion physics; next generation commercial/civil space transportation and reusable launch systems technology; spaceport development; potential manned and unmanned space missions; and advances in energy conversion technologies. STAIF-2000 is co-sponsored by NASA Headquarters and Field Centers, DOE, and The Boeing Company, in cooperation with major professional societies. Government aerospace industry and universities exhibit and present papers.

The book Radioisotopes - Applications in Physical Sciences is divided into three sections namely: Radioisotopes and Some Physical Aspects, Radioisotopes in Environment and Radioisotopes in Power System Space Applications. Section I contains nine chapters on radioisotopes and production and their various applications in some physical and chemical processes. In Section II, ten chapters on the applications of radioisotopes in environment have been added. The interesting articles related to soil, water, environmental dosimetry/tracer and composition analyzer etc. are worth reading. Section III has three chapters on the use of radioisotopes in power systems which generate electrical power by converting heat released from the nuclear decay of radioactive isotopes. The system has to be flown in space for space exploration and radioisotopes can be a good alternative for heat-to-electrical energy conversion. The reader will very much benefit from the chapters presented in this section.
