Taschenbuch. Condizione: Neu. Neuware -heterogeneous structures, especially when the data quality is not very high. GAUTIER et al. perform tomographic inversion of local earthquake arrival times for crustal structure and earthquake locations in the actively rifting Gulf of Corinth. The velocities image the rift basin and the hypocenters image a regional-scale detachment fault. Inthe third group of papers, SNIEDER reviews theoretical concepts governing changes of coda waves due to small localized perturbations in the medium properties or source location, and describes how to estimatethe resulting meanand varianceofthe travel-time perturbations. CAMPILLO reviews theoretical results on properties of coda waves in asymptotic multiple-scattering regime, and how to construct Green functions from coda waves and ambient seismic noise. The results are illustrated with applications of imaging velocity structures in Alaska and California. WEGLER et al. use the theory of radiative transfer to model the transport of seismic energy in 2-D and 3-D acoustic random media. The theory accounts correctly for the direct wave front, envelope broadening caused by multiple forward scattering, and late coda caused by multiple wide-angle scattering. However, for very heterogeneous media the radiative transfer results di er from those of the full wave equation. ZENG develops a set of scattered wave energy equations that include scattered surface waves and conversions of body waves to surface wave scattering. Numerical results show that scattered wave energy can be approximated well by body-wave scattering at earlier times and short distances, but at large distances scattered surface waves dominate the scattered body waves at surface stations.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 380 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This second special issue is in honor of Keiiti Aki. It focuses on recent advances in quantifying and interpreting heterogeneities in lithosperic structures and earthquake behavior. The volume provides a combination of reviews, methodological studies and applications on topics related to Aki's pioneering contributions. The discussed subjects include research associated with dynamic earthquake rupture. It also includes material on Aki and a list of his publications. 380 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is intended to coverthe presentstatus of the mathematicaltools used to deal with problems related to slow rare ed ows. The meaning and usefulness of the subject, and the extent to which it is covered in the book, are discussed in some detail in the introduction. In short, I tried to present the basic concepts and the techniques used in probing mathematical questions and problems which arise when studying slow rare ed ows in environmental sciences and micromachines. For the book to be up-to-date without being excessively large, it was necessary to omit some topics, which are treated elsewhere, as indicated in the introd- tion and, whenever the need arises, in the various chapters of this volume. Their omission does not alter the aim of the book, to provide an understanding of the essential mathematical tools required to deal with slow rare ed ows and give the background for a study of the original literature. Although I have tried to give a rather complete bibliographical coverage,the choice of the topics and of the references certainly re ects a personal bias and I apologize in advance for any omission. I wish to thank Lorenzo Valdettaro, Antonella Abb` a, Silva Lorenzani and Paolo Barbante for their help with pictures and especially Professor Ching Shen for his permission to reproduce his pictures on microchannel ows. 166 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Rheumatoid Arthritis (RA) represents a complex disease where the inheritable component has been estimated to be up to 60%. This PIR volume deals with the genetic basis and regulation of rheumatic diseases. The first part of the book describes genetic studies on rheumatic diseases. The second part deals with the shared heredity of rheumatic diseases, e.g., RA, lupus and ankylosing spondylitis. The third part of the volume describes tools for analysing genetic complexity, ranging from animal models to new molecular tools. The volume is essential reading for researchers and clinicians from rheumatology, inflammation research, immunology, and cell and molecular biology. 178 pp. Englisch.
