This book presents an up-to-date overview of cathodoluminescence microscopy and spectroscopy in the field of geosciences. For a decade, no books have been dedicated to this topic. This volume includes new important data on cathodoluminescence spectroscopy, physical parameters and systematic spectral analysis of doped minerals. Each chapter, written by a well-known specialist, covers classic and new fields of application such as carbonate diagenesis, silicates, brittle deformation in sandstones, gemstone recognition, biomineralization, economic geology or geochronology. It will be useful to all scientists, graduate students and professional engineers throughout the geosciences community.

The contributions provide an overview of research in tele- communications and distributed systems. The main part con- concentrates on the evaluation of the CCITT recommendations and ISO standards with respect to OSI and ISDN and user ser- vices. It also reviews new applications that are becoming a- vailable in modern offices, manufacturing, and the public domain. Different approaches are discussed as to how these applications can be builtmore easily with advanced program- ming rools. Deals with operating systems support for commu- nication systems.
