It's a time of change. While mankind is adjusting to its first encounter with an alien civilisation, black-ops soldier Jim Leyton has absconded from the agency that trained him, and allied himself with a mysterious faction in order to rescue the woman he loves. Since his death, scientist and businessman Philip Kaufman has realised that there is more to the virtual world than he'd suspected. Yet it soon becomes clear that all is not well in Virtuality. Both men begin to suspect that the much heralded 'First Contact' was anything but, and that a sinister con is being perpetrated on the whole of humankind. Now all they have to do is prove it.

The sounds produced by geophonic, biophonic and technophonic sources are relevant to the function of natural and human modified ecosystems. Passive recording is one of the most non-invasive technologies as its use avoids human intrusion during acoustic surveys and facilitates the accumulation of huge amounts of acoustical data. For the first time, this book collates and reviews the science behind ecoaucostics; illustrating the principles, methods and applications of this exciting new field. Topics covered in this comprehensive volume include; the assessment of biodiversity based on sounds emanating from a variety of environments the best technologies and methods necessary to investigate environmental sounds implications for climate change and urban systems the relationship between landscape ecology and ecoacoustics the conservation of soundscapes and the social value of ecoacoustics areas of potential future research. An invaluable resource for scholars, researchers and students, Ecoacoustics: The Ecological Role of Sounds provides an unrivalled set of ideas, tools and references based on the current state of the field.

This review of Switzerland's environmental conditions and policies evaluates progress in reducing the pollution burden, improving natural resource management, integrating environmental and economic policies, and strengthening international co-operation.

The result of the second Appalachian conference on neurodynamics, this volume focuses on the problem of "order," its origins, evolution, and future. Central to this concern lies our understanding of time. Both classical and quantum physics have developed their conceptions within a framework of time symmetry. Divided into four major sections, this book: * provides refreshingly new approaches to the problem of the evolution of order, indicating the directions that need to be taken in subsequent conferences which will address learning and memory more directly; * addresses the issue of how information becomes transmitted in the nervous system; * shows how patterns are constructed at the synaptodendritic level of processing and how such pattern construction relates to image processing; and * deals with the control operations which operate on image processing to construct entities such as visual and auditory objects such as phonemes. The aim of the conference was to bring together professionals to exchange ideas -- some were fairly worked out; others were in their infancy. As a result, one of the most valuable aspects of the conference is that it fostered lasting interactive relationships among these leading researchers.

An international panel of expert clinicians and leading scientists comprehensively review the clinical and basic science of this disease and its relatives, including acquired neuromytonia and Lambert-Eaton syndrome. For the clinician, the book describes the wide range of signs and symptoms that make these diseases difficult to diagnose, review in depth the available diagnostic methods and their limitations, offer practical treatment recommendations based on years of experience, and discuss several promising treatments now emerging. For the basic scientist, the text illuminates neuromuscular structure and function, describes in detail the acetylcholine receptor (the central target of pathology in myasthenia gravis), and illuminates the autoimmune pathogenesis.
