This book presents contributions by experts from diverse disciplines, estimating the global levels of biogeogenic and anthropogenic emissions of organometal(loid) compounds, and thus presenting insight into processes which influence the genesis, as well as the distribution and stability of these species and their interaction with each other and other matrix compounds. The authors evaluate identify potential "hot spots" of organometal(loid)s, which can negatively influence ecosystems and human health.
The combination of fast, low-latency networks and high-performance, distributed tools for mathematical software has resulted in widespread, affordable scientific computing facilities. Practitioners working in the fields of computer communication networks, distributed computing, computational algebra and numerical analysis have been brought together to contribute to this volume and explore the emerging distributed and parallel technology in a scientific environment. This collection includes surveys and original research on both software infrastructure for parallel applications and hardware and architecture infrastructure. Among the topics covered are switch-based high-speed networks, ATM over local and wide area networks, network performance, application support, finite element methods, eigenvalue problems, invariant subspace decomposition, QR factorization and Todd-Coxseter coset enumeration.
PET and PET-CT in Oncology describes the principles of positron emission tomography and is a useful resource for incorporating the technique in clinical practice. In a clear and straightforward fashion, the book offers instructive information and overviews of the basic principles of PET and PET-CT as well as the routine clinical PET scanning procedures for all important oncological indications. It is designed to serve as a reference work for specialists in nuclear medicine and radiology (including therapy planning) and for oncologists. It also provides student and physicians in other medical specialities with a general introduction to the effective integration of this modern technique into routine clinical diagnostics. Above all, this volume illustrates the importance of PET and PET-CT in comparison with other imaging techniques.
This book presents a state-of-the art review of current perspectives on Communications and Multimedia Security. It contains the Proceedings of the 3rd Joint Working Conference of IFIP TC6 and TC11, arranged by the International Federation for Information Processing and held in Athens, Greece in September 1997. The book aims to cover the subject of Communications and Multimedia Systems Security, as fully as possible. It constitutes an essential reading for information technology security specialists; computer professionals; communication systems professionals; EDP managers; EDP auditors; managers, researchers and students working on the subject.
Universities are undergoing an extraordinary transformation. Digital technologies have altered research and teaching, while modern communication media and social media promote an interactive exchange of information with society that has accelerated international knowledge transfer. At the same time, new educational careers are available in growing higher education fields. How can universities meet these and other challenges? Reputable experts come together in this book to design scenarios for universities in the 21st century.

Volume XXVIII contains five review articles covering the following areas - digital holography, a field that has found useful applications in connection with data processing and data storage, for 3-d displays and in providing new types of optical components, for example, holographic gratings; - basic investigations concerned with new technologies that may lead to better optical communication systems and improved limits of measurement than are expected from the traditional interpretation of quantum-mechanical measurement theory; - a review of our current understanding of quantum coherence properties of stimulated Raman scattering; - an account of techniques developed in recent years in the field of interferometry, for improvements of high precision measurements; - the fascinating phenomenon of quantum jumps, which were introduced in the theory of atomic spectra by Niels Bohr in 1913.
