Taschenbuch. Zustand: Neu. Neuware - In 1999, the IFAC/IFIP Workshop on Real Time Programming (WRTP) joined forces with the Workshop on Active and Real-Time Database Systems (ARTDB). Both series of workshops provide a forum for exchanging information on recent scientific and technological advances and practices in real time computing.

Buch. Zustand: Neu. Neuware - Genetic Aberrancies and Neurodegenerative Disorders presents critical reviews and emerging findings concerning the roles of genetic mutations and polymorphisms in the pathogenesis of a range of neurological disorders including Alzheimer's and Parkinson's diseases, trinucleotide repeat disorders, stroke, epilepsy and others. This volume, written by leading experts, brings together fundamental information concerning the roles of inherited traits in the pathogenesis of different neurodegenerative disorders. In addition to providing a catalogue of the known genetic alterations that are linked to specific neurodegenerative disorders, the chapters detail the current state of understanding of the cellular and biochemical mechanisms whereby the genetic aberrancies lead to neuronal dysfunction and degeneration. The emerging picture of each disorder, painted by pathological, biochemical and molecular brushes, suggests that they share key mechanisms including increased levels of oxidative stress, perturbed ion homeostasis, mitochondrial dysfunction and apoptotic proteolytic cascades. The existence of specific molecular defects provides the opportunity to design experiments that can establish the precise pathogenic mechanism of a specific mutation or genetic risk factor. The value of this approach is exemplified by recent studies of how mutations in Cu/Zn-superoxide dismutase cause amyotrophic lateral sclerosis and how presenilin mutations result in early-onset Alzheimer's disease. A theme developed among the different chapters is that events that occur during aging predispose neurons to genetic aberrancies that promote degenerative cascades, and that specific genetic defects exert their influenceon particular populations of neurons in a disorder-specific manner. The chapters in this volume will stimulate readers to generate new hypotheses concerning the pathogenic mechanisms of genetic aberrancies that can be experimentally tested.

Buch. Zustand: Neu. Neuware - This series is designed to provide a vehicle in which investigators, who have demonstrated a high degree of competence in some aspect of free radical chemistry, can present a particular area of interest. The series encompasses a wide variety of topics which are of current interest.

Buch. Zustand: Neu. Neuware - This volume presents work from six different groups working on various aspects of cycloaddition chemistry. Jose Mascarenas gives us a very interesting account of the chemistry of &Bgr;-alkoxy-&ggr;-pyrones and related species. Al Padwa and Chris Staub discuss further advances in rhodium carbenoid chemistry and the unusual cycloaddition processes possible with these intermediates. Higher order cycloadditions mediated by transition metals highlight Jim Rigby's update on his group's efforts in this area. Lily Lee and John Snyder present us with a detailed account of the indole ring as a dienophile, challenging us to consider the untapped potential in this area. Brian Keay and Ian Hunt discuss the intramolecular Diels-Alder reactions of furan; a report that is both top-notch science, and what could be a great learning tool for students who need to see how fundamental chemical principles can and should be applied to synthetic problems. Finally, Kay Brummond introduces us to a new version of the Pauson-Khand reactions, one that will no doubt be further exploited in productive ways by her group well into the future.

Buch. Zustand: Neu. Neuware - The International Conference on Mechanical Design and Production has over the years established itself as an excellent forum for the exchange of ideas in these established fields. This book offers a sample that represents the quality and breadth of both the work and the conference.
