It is over a quarter of a century since the discovery of out?ows from young stars. The intervening years have led to remarkable advances in our understanding of this phenomenon. Much of the progress can be attributed to advances in facilities and technologies, including not only larger telescopes but also improved instrument and detector performance. In addition protostellar out?ows have now been imaged from the ground and space at high spatial resolution, e. g. with HST, and at a wide - riety of wavelengths from X-rays to radio waves, revealing more and more about their physics. This veritable revolution in observation has been accompanied by an exponential growth in our ability to numerica...
The reviews and highlights included in this book of proceedings of the plenary sessions, of the Joint European and National Astronomical Meeting (2002), cover some of the major fields and projects which will determine the research in astronomy in the next decades. The highlights have been presented by young astronomers from several European countries, selected from a list of proposals submitted by different institutions across Europe. This book reflects the multi-disciplinarity and interaction that took place in the meeting. By including reviews on space and ground-based observational programmes, the scientific topics are associated with the new observational efforts in instrumentation. These projects, under development, are expected to drive the research in the coming decades. With such a wide and interdisciplinary coverage this book provides a comprehensive review on the present status and expectations for some of the major fields in astrophysics. This work is of great relevance for students and researchers alike, as it provides an introductory approach to a wide range of fields in Astronomy, but also includes some detailed reviews for the major topics in each field.
The twenty-first century has opened with a rapidly changing map of Christianity. While its influence is waning in some of its traditional Western strongholds, it is growing at a phenomenal pace in the global South. And yet this story has largely eluded the corporate news brokers of the West. Layered as it is with countless personal and corporate stories of remarkable faith and witness, it nevertheless lies ghostlike behind the newsprint and webpages of our print media, outside the camera's vision on the network evening news. Miriam Adeney has lived, traveled and ministered widely. She has walked with Christians in and from the far reaches of the globe. As she pulls back the veil on real Christians--their faith, their hardships, their triumphs and, yes, their failures--an inspiring and challenging story of a kingdom that knows no borders takes shape. This is a book that coaxes us out of our comfortable lives. It beckons us to expand our vision and experience of the possibilities and promise of a faith that continues to shape lives, communities and nations.
During the past few decades, plasma science has witnessed a great growth in laboratory studies, in simulations, and in space. Plasma is the most common phase of ordinary matter in the universe. It is a state in which ionized matter (even as low as 1%) becomes highly electrically conductive. As such, long-range electric and magnetic fields dominate its behavior. Cosmic plasmas are mostly associated with stars, supernovae, pulsars and neutron stars, quasars and active galaxies at the vicinities of black holes (i.e., their jets and accretion disks). Cosmic plasma phenomena can be studied with different methods, such as laboratory experiments, astrophysical observations, and theoretical/computat...

"From a mission field to a missions sender." These words capture the story of the Brazilian evangelical church, which has gone from receiving missionaries in the nineteenth and twentieth centuries to becoming a movement that presently sends out more global laborers than the churches of England or Canada do. After narrating Brazil's missional shift, in this volume Smither addresses one fascinating element of the story--Brazilian evangelical efforts in the Arab world. How have Brazilians adapted culturally among Arabs, how have they approached ministry, and how have they cultivated a theology of mission in the process? Brazilian Evangelical Missions in the Arab World gives the reader insights from one emerging missions movement with an eye toward a more comprehensive view of the global church.
These proceedings are the result of a three-day meeting held in Oogliani (Italy), on October 2-4 2003, whose title was "VIrtual Astrophysical Jets 2003". Our goal in convening this meeting was to gather some of the scientists among the most active in the field of numerical simulations and modelling of astrophysi cal jets. For keeping the participants close to the "real world", we also invited a few observers to give up-to-date reviews outlining the state-of-the-art of jet observations. The principal aim of the meeting was thus to present and critically discuss the state-of-the-art numerical simulations, analytical models and laboratory ex periments for reproducing the main aspects of astroph...
The international colloquium Open Issues in Local Star Formation and Early Stellar Evolution was focused on: the physics of young stellar objects, which are observed with increasing angular resolution by the new generation of telescopes; and the processes that triggered large scale star formation in the solar neighbourhood. The scientific presentations were not limited to these two main topics as many new and interesting results related to star formation have been obtained.; The participants presented new findings in the fields of stellar groups and associations; young stellar objects; disks; outflows and jets; the ISM conditions for star formation; and early stages of star formation. The discussions on open issues, representing problems and unanswered questions, should make this book particularly useful for researchers and PhD students.
