Buch. Condizione: Neu. Neuware - One prerequisite for the evolution of multicellular organisms was the invention of mechanisms by which cells could adhere to one another. At some point in our history, dividing cells no longer went their separate protozoic ways in the primordial oceans, but instead found that by maintaining an association, by sticking together but not fusing, numerous evolutionary advantages became possible. The subsequent development of specialized tissues and organs depended on the elaboration of incredibly sophisticated, regulatable cell-to-cell adhesion mechanisms which are known to operate in biological processes as diverse as the growth of the embryo, the immune response, the establishment of connections between nerve cells, and arteriosclerosis, to name just a few. Although we can only guess at the ancestral mechanisms that fostered the first primitive intercellular unions, some one billion years ago, we now recognize contemporary molecular 'themes' with presumably ancient origins that mediate cell-cell interactions.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Vertebrate evolution has led to the convergent appearance of many groups of originally terrestrial animals that now live in the sea. Among these groups are familiar mammals like whales, dolphins, and seals. There are also reptilian lineages (like plesiosaurs, ichthyosaurs, mosasaurs, thalattosaurs, and others) that have become sea creatures. Most of these marine reptiles, often wrongly called 'dinosaurs', are extinct. This edited book is devoted to these extinct groups of marine reptiles. These reptilian analogs represent useful models of the myriad adaptations that permit tetrapods to live in the ocean. 501 pp. Englisch. …

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Computer simulation techniques are now having a major impact on almost all areas of the physical and biological sciences. This book concentrates on the application of these methods to inorganic materials, including topical and industrially relevant systems including zeolites and high Tc superconductors. The central theme of the book is the use of modern simulation techniques as a structural tool in solid state science. Computer Modelling in Inorganic Crystallography describes the current range of techniques used in modeling crystal structures, and strong emphasis is given to the use of modeling in predicting new crystal structures and refining partially known structures. It also reviews new opportunities being opened up by electronic structure calculation and explains the ways in which these techniques are illuminating our knowledge of bonding in solids. 340 pp. Englisch. …

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Furunculosis: Multidisciplinary Fish Disease Research presents a fascinating insight into the opinions and the controversies which have led to current knowledge of this disease. It is the first book to cover one single fish disease by presenting not just the reviews, but also critical examination of the progress made by various disciplines. The multidisciplinary approach of the book makes it a valuable guide for veterinarians, fisheries biologists, and fish farm managers, as well as an excellent instructional text for students. The volume explores current research strategies and projects what developments can be expected in each field. 529 pp. Englisch.…
