Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -[Infotext]((Kurztext))These are the proceedings of the 7th International Conference on Hyperbolic Problems, held in Zürich in February 1998. The speakers and contributors have been rigorously selected and present the state of the art in this field. The articles, both theoretical and numerical, encompass a wide range of applications, such as nonlinear waves in solids, various computational fluid dynamics from small-scale combustion to relativistic astrophysical problems, multiphase phenomena and geometrical optics. ((Volltext))These proceedings contain, in two volumes, approximately one hundred papers presented at the conference on hyperbolic problems, which has focused to a large extent on the laws of nonlinear hyperbolic conservation. Two-fifths of the papers are devoted to mathematical aspects such as global existence, uniqueness, asymptotic behavior such as large time stability, stability and instabilities of waves and structures, various limits of the solution, the Riemann problem and so on. Roughly the same number of articles are devoted to numerical analysis, for example stability and convergence of numerical schemes, as well as schemes with special desired properties such as shock capturing, interface fitting and high-order approximations to multidimensional systems. The results in these contributions, both theoretical and numerical, encompass a wide range of applications such as nonlinear waves in solids, various computational fluid dynamics from small-scale combustion to relativistic astrophysical problems, multiphase phenomena and geometrical optics. 513 pp. Englisch.

The proton pump inhi bitors are tailored for their purpose. They accumulate in the target cell, are activated by acid and bind strongly to the specific target - the proton pump. The clinical superiority of the proton pump inhibitors is due not only to their high efficacy but also to the long duration of the acid inhibition in comparison with other antisecretory drugs. At present when drug discovery mostly relies on identification and characterization of potential targets by genome research, molecular biology, combinatorial chemistry and automated screening, it seems worthwhile to present the development of the tITst proton pump inhibitor - omeprazol- starting from a chemical structure with an observed antisecretory effect but also severe toxic effects that had to be eliminated. As always, basic and applied research operate luind in hand to optimize the delicate balance be tween efficacy and safety of a new drug. This goal often involves time and many different specialists. 251 pp. Englisch.

There were times when it seemed that it had borne its best fruit already and would give way to investigation of deeper levels of matter. Today this sounds like rash thinking. Modern experimental techniques have led to discoveries of numerous new quantum effects in solid state, optics and elsewhere. Quantum mechanics is thus gradually becoming a basis for many branches of applied physics, in this way entering our everyday life. While the dynamic laws of quantum mechanics are well known, a proper theoretical understanding requires methods which would allow us to de rive the abundance of observed quantum effects from the first principles. In many cases the rich structure hidden in the Schr6dinger equation can be revealed only using sophisticated tools. This constitutes a motivation to investigate rigorous methods which yield mathematically well-founded properties of quantum systems. 398 pp. Englisch.
