Planetary Nebulae (IAU S323): Multi-Wavelength Probes of Stellar and Galactic Evolution Details

Planetary nebulae, glowing shells of ionized gas, are the spectacular products of the evolution of low- and intermediate-mass stars. For astrophysicists, they are important laboratories for the understanding of atomic, molecular, dust, and plasma processes in different cosmic environments; they enable the exploration of the fundamental physics of single and binary star evolution including nucleosynthesis, rotation, mass transfer and loss, and magnetic fields; and they help trace stellar populations, the kinematics, and chemistry of galaxies including our own galaxy, the Milky Way. This volume reviews the current status of this vibrant research field in the form of invited reviews, contributed talks, and posters presented at the IAU Symposium 323. It should be of interest to researchers and advanced students interested in this field and in related fields, including stellar physics, the interstellar medium, and Galactic and extragalactic astronomy.

Principles of Seismology

Category: Livres anglais et trangers,Science,Earth Sciences

Principles of Seismology Details

The second edition of Principles of Seismology has been extensively revised and updated to present a modern approach to observation seismology and the theory behind digital seismograms. It includes: a new chapter on Earthquakes, Earth's structure and dynamics; a considerably revised chapter on instrumentation, with new material on processing of modern digital seismograms and a list of website hosting data and seismological software; and 100 end-of-chapter problems. The fundamental physical concepts on which seismic theory is based are explained in full detail with step-by-step development of the mathematical derivations, demonstrating the relationship between motions recorded in digital seismograms and the mechanics of deformable bodies. With chapter introductions and summaries, numerous examples, newly drafted illustrations and new color figures, and an updated bibliography and reference list, this intermediate-level textbook is designed to help students develop the skills to tackle real research problems.

Fatigue Design of Marine Structures

Category: Livres anglais et trangers,Professional & Technical,Engineering

Fatigue Design of Marine Structures Details

Fatigue Design of Marine Structures provides students and professionals with a theoretical and practical background for fatigue design of marine structures including sailing ships, offshore structures for oil and gas production, and other welded structures subject to dynamic loading such as wind turbine structures. Industry expert Inge Lotsberg brings more than forty years of experience in design and standards-setting to this comprehensive guide to the basics of fatigue design of welded structures. Topics covered include laboratory testing, S-N data, different materials, different environments, stress concentrations, residual stresses, acceptance criteria, non-destructive testing, improvement methods, probability of failure, bolted connections, grouted connections, and fracture mechanics. Featuring twenty chapters, three hundred diagrams, forty-seven example calculations, and resources for further study, Fatigue Design of Marine Structures is intended as the complete reference work for study and practice.

Ecology of Fishes on Coral Reefs

Category: Livres anglais et trangers,Science,Biological Sciences

Ecology of Fishes on Coral Reefs Details

The local diversity and global richness of coral reef fishes, along with the diversity manifested in their morphology, behaviour and ecology, provides fascinating and diverse opportunities for study. Reflecting the very latest research in a broad and ever-growing field, this comprehensive guide is a must-read for anyone interested in the ecology of fishes on coral reefs. Featuring contributions from leaders in the field, the 36 chapters cover the full spectrum of current research. They are presented in five parts, considering coral reef fishes in the context of ecology, patterns and processes, human intervention and impacts, conservation, and past and current debates. Beautifully illustrated in full-colour, this book is designed to summarise and help build upon current knowledge and to facilitate further research. It is an ideal resource for those new to the field as well as for experienced researchers.

Ideophones and the Evolution of Language

Category: Livres anglais et trangers,Reference,Words & Language

Ideophones and the Evolution of Language Details

Ideophones have been recognized in modern linguistics at least since 1935, but they still lie far outside the concerns of mainstream (Western) linguistic debate, in part because they are most richly attested in relatively unstudied (often unwritten) languages. The evolution of language, on the other hand, has recently become a fashionable topic, but all speculations so far have been almost totally data-free. Without disputing the tenet that there are no primitive languages, this book argues that ideophones may be an atavistic throwback to an earlier stage of communication, where sounds and gestures were paired in what can justifiably be called a 'prelinguistic' fashion. The structure of ideophones may also provide answers to deeper questions, among them how communicative gestures may themselves have emerged from practical actions. Moreover, their current distribution and behaviour provide hints as to how they may have become conventional words in languages with conventional rules.
