Book Description
The discovery of the ?rst case of superluminal radio jets in our galaxy in 1994 from the bright and peculiar X-ray source GRS 1915+105 has opened the way to a major shift in the direction of studies of stellar-mass accreting binaries. The past decade has seen an impressive increase in multi-wavelength studies. It is now known that all black hole binaries in our galaxy are radio sources and most likely their radio emission originates from a powerful jet. In addition to the spectacular events related to the ejection of superluminal jets, steady jets are known from many systems. Compared with their supermassive cousins, the nuclei of active galaxies, stellar-mass X-ray binaries have the advantage of varying on time scales accessible within a human life (sometimes even much shorter than a second). This has led to the ?rst detailed studies of the relation between accretion and ejection. It is even possible that, excluding their “soft” periods, the majority of the power in gal- tic sources lies in the jets and not in the accretion ?ows. This means that until a few years ago we were struggling with a physical problem, accretion onto compact objects, without considering one of the most important components of the system. Models that associate part of the high-energy emission and even the fast aperiodic variability to the jet itself are now being proposed and jets can no longer be ignored.

Book Description
As a result of significant research over the past 20 years, black holes are now linked to some of the most spectacular and exciting phenomena in the Universe, ranging in size from those that have the same mass as stars to the super-massive objects that lie at the heart of most galaxies, including our own Milky Way. This book first introduces the properties of simple isolated holes, then adds in complications like rotation, accretion, radiation, and magnetic fields, finally arriving at a basic understanding of how these immense engines work. Black Hole Astrophysics • reviews our current knowledge of cosmic black holes and how they generate the most powerful observed pheonomena in the Universe; • highlights the latest, most up-to-date theories and discoveries in this very active area of astrophysical research; • demonstrates why we believe that black holes are responsible for important phenomena such as quasars, microquasars and gammaray bursts; • explains to the reader the nature of the violent and spectacular outfl ows (winds and jets) generated by black hole accretion.

Book Description
In 2008, the European FP6 JETSET project ended. JETSET, for Jet, Simulations, Experiments, and Theory, was a joint research network of European expert teams on protostellar jets. The present proceedings are a collection of contributions presenting new results obtained by those groups since the end of the JETSET program. This is also the occasion to celebrate Kanaris Tsinganos’ important contributions to this network and for his enlightening insight in the subject that inspired us all. Some of the former JETSET students are now in the academic world and the subject has never been so alive. So we present here a collection of results of what has been done in the field of protostellar jets in the past ten years from the theoretical, numerical, observational and experimental point of view. We also present new challenges in the field of protostellar jets and what we should expect from the development of new instruments and new numerical codes in the near future. We also gather results on the impact of the study of protostellar jets on other jet studies in particular on relativistic jets. As a matter of fact, it is time for a new network.

Book Description
Circadian rhythms have been shown to be ubiquitous and critically important in the experimental laboratory, accounting for the difference between life and death in response to identical stimulus. The partly endogenous nature of circadian rhythms has been well documented and methods for their characterisation have been developed enabling the cellular and molecular mechanisms to be understood. Chronobiology and Chronomedicine aims to provide a review of these mechanisms underlying circadian rhythms and illustrate the role of the brain’s suprachiasmatic nuclei in the ‘pace-making’ process and the effects caused by ‘clock genes’ present in almost all cells. Beyond the mechanisms involved, the book discusses the relationship between body systems, disease, and proper circadian function; in particular, how disruption of the circadian rhythm is associated with ill health and disease status from observations made at the organismic level. The book is organised to be an ideal introduction for the postgraduate in various fields, reviewing developments and outlining methods to show the depth and breadth of chronobiology and chronomedicine, as well as an invaluable companion to researchers and healthcare professionals working in the field with an interest in developing novel therapeutic approaches.

Book Description
'This ambitious book draws upon a wide variety of literature in developing a comprehensive theory of entrepreneurship, ranging from the discovery of entrepreneurial activities, to industry differences in entrepreneurial activity, to the organizing process. It represents a major contribution to the field.' - Arnold C. Cooper, Purdue University, US 'Professor Scott Shane provides a deep and comprehensive discussion of the individual-opportunity nexus in entrepreneurship. Eschewing the usual approaches of either focusing exclusively on the individuals and their motivations and actions or focusing exclusively, almost always ex-post, on the economic potential of opportunities, Scott Shane fixes his gaze squarely on the nexus of the individual and the opportunity. It is this nexus that I believe is the building block for a better understanding of the entrepreneurial phenomenon.' - From the foreword by Sankaran Venkataraman In the first exhaustive treatment of the field in 20 years, Scott Shane extends the analysis of entrepreneurship by offering an overarching conceptual framework that explains the different parts of the entrepreneurial process - the opportunities, the people who pursue them, the skills and strategies used to organize and exploit opportunities, and the environmental conditions favorable to them - in a coherent way.

Book Description
"Offers an intense scholarly experience in its comprehensiveness, its variety of voices and its formal organization... the editors took a risk, experimented and have delivered a much-needed resource that upends the status-quo." - Architectural Histories, journal of the European Architectural History Network "Architectural theory interweaves interdisciplinary understandings with different practices, intentions and ways of knowing. This handbook provides a lucid and comprehensive introduction to this challenging and shifting terrain, and will be of great interest to students, academics and practitioners alike." - Professor Iain Borden, UCL Bartlett School of Architecture "In this collection, architectural theory expands outward to interact with adjacent discourses such as sustainability, conservation, spatial practices, virtual technologies, and more. We have in The Handbook of Architectural Theory an example of the extreme generosity of architectural theory. It is a volume that designers and scholars of many stripes will welcome." - K. Michael Hays, Eliot Noyes Professor of Architectural Theory, Harvard University The SAGE Handbook of Architectural Theory documents and builds upon the most innovative developments in architectural theory over the last two decades. Bringing into dialogue a range of geographically, institutionally and historically competing positions, it examines and explores parallel debates in related fields. The book is divided into eight sections: Power/Difference/Embodiment Aesthetics/Pleasure/Excess Nation/World/Spectacle History/Memory/Tradition Design/Production/Practice Science/Technology/Virtuality Nature/Ecology/Sustainability City/Metropolis/Territory. Creating openings for future lines of inquiry and establishing the basis for new directions for education, research and practice, the book is organized around specific case studies to provide a critical, interpretive and speculative enquiry into the relevant debates in architectural theory.
