Hot Cracking Phenomena In Welds. Although the avoidance of hot cracking still represents a major topic in modern fabrication welding components, the phenomena have not yet been fully understood. Through the 20 individual contributions from experts all over the world the present state of knowledge about hot cracking during welding is defined, and the subject is approached from four different viewpoints. The first chapter provides an overview of the various hot cracking phenomena. Different mechanisms of solidification cracking proposed in the past decades are summarized and new insight is particularly given into the mechanism of ductility dip cracking. The effects of different alloying elements on the hot cracking resistance of various materials are shown in the second chapter and, as a special metallurgical effect, the initiation of stress corrosion cracking at hot cracks has been highlighted. The third chapter outlines how numerical analyses and other modelling techniques can be utilized to describe hot cracking phenomena and how such results might contribute to the explanation of the mechanisms. Various hot cracking test procedures are presented in the final chapter with a special emphasis on standardization. For the engineering and natural scientists in research and development the book provides both, new insight and a comprehensive overview of hot cracking phenomena in welds. The contributions additionally give numerous individual solutions and helpful advice for international welding engineers to avoid hot cracking in practice. Furthermore, it represents a very helpful tool for upper level metallurgical and mechanical engineering students.

In The Wake Of Chaos. Chaos theory has captured scientific and popular attention. What began as the discovery of randomness in simple physical systems has become a widespread fascination with "chaotic" models of everything from business cycles to brainwaves to heart attacks. But what exactly does this explosion of new research into chaotic phenomena mean for our understanding of the world? In this timely book, Stephen Kellert takes the first sustained look at the broad intellectual and philosophical questions raised by recent advances in chaos theory—its implications for science as a source of knowledge and for the very meaning of that knowledge itself.

The Roots Of Consciousness. A clinical psychologist and expert on parapsychology looks at the way history, folklore, and science shape the understanding of psychic ability-- Explores the idea that telepathy, clairvoyance, precognition, psychokinesis, astral projection, and other such powers are latent within everyone-- Illustrated with 100 black-and-white photographs and illustrationsThe title for The Roots of Consciousness was inspired by a statement of cosmologist Arthur M. Young, who cautioned against seeking only the "flowers of consciousness," such as clairvoyance and telepathy, considering them no more than the "intriguing foliage" of psychology. Author Jeffrey Mishlove, however, believes that these and other psychic powers are not just for show, but are "rooted in the essential core of our existence."In this thorough book, Young makes the case that, although alien to Western society's ways of thinking, psychic phenomena is deeply embedded within consciousness. He looks at: -- History: studies shamanistic traditions; the ancient civilizations of India, China, Greece, Mesopotamia, and Rome; early Hebrews, Christians, and hermits; and Islamic beliefs and ideas in Medieval Europe, the Renaissance, and the Age of Enlightenment-- Folklore: examines astrology; astral projection and out-of-body experiences; faith healing; auras; communication with angels and other spirits; contact with UFOs and aliens; near-death experiences; mind over matter; and practical applications like dowsing and psychic police work-- Science: chronicles and evaluates formal research into psychic capacities, especially ESP; hypnosis; psychic performers such as Pavel Stepanek, Bill Delmore, and Uri Geller; psychokinesisThroughout the book, Mishlove presents the viewpoints of both believers and nonbelievers as a further means of introducing the language and concepts of psychic functioning.

Galaxies In The Universe. This extensively illustrated book presents the astrophysics of galaxies since their beginnings in the early Universe. It has been thoroughly revised to take into account the most recent observational data, and recent discoveries such as dark energy. There are new sections on galaxy clusters, gamma ray bursts and supermassive black holes. The authors explore the basic properties of stars and the Milky Way before working out towards nearby galaxies and the distant Universe. They discuss the structures of galaxies and how galaxies have developed, and relate this to the evolution of the Universe. The book also examines ways of observing galaxies across the whole electromagnetic spectrum, and explores dark matter and its gravitational pull on matter and light. This book is self-contained and includes several homework problems with hints. It is ideal for advanced undergraduate students in astronomy and astrophysics.

Fundamentals Of Electrical Engineering. This highly successful survey of the fundamental principles of modern electrical engineering offers an in-depth examination of four major topics: circuits, electronics, digital systems and electromagnetics. Advanced concepts such as resistive analysis, time-domain and frequency-domain analysis, sequential and combinational logic and elementary system principles, are discussed in detail. This updated edition includes a new chapter on the circuit analysis software SPICE, with a particular focus on the PC-version PSPICE. Numerous drill exercises illustrating concepts from the text have been added and 346 out of the 1182 end-of-chapter problems appear for the first time.Key Features:* The only fundamentals book to cover 'SPICE' (the circuits analysis software)* Covers most topics in greater depth than most introductory books* Provides maximum instructor and course flexibility with a modular, five-part organisation* Core textbook for first year undergraduatesSupplement:Solutions Manual: 0195111249Contents:I.

The Problem Of Mental Deficiency. This is the first detailed assessment of the development and implementation of social policy to deal with the problem of the `mentally deficient' in Britain between 1870 and 1959. Mathew Thomson analyses all the factors involved in the policy-making process, beginning with the politics of the legislature and showing how the demands of central government were interpreted by local authorities, resulting in a wide and varied distribution of medical, institutional, and community care in different parts of the country. The efforts of health professionals, voluntary organizations and the families themselves are considered, alongside questions about the influence of changing concepts of class, gender, and citizenship. The author queries the belief that the policy of segregation was largely unsuccessful, and reveals a hitherto unrecognized system of care in the community. He reframes our understanding of the campaign for sterilization and examines why British policy-makers avoided extremist measures such as the compulsory sterilization introduced in Germany and parts of the US during this period. Thomson shows that the problem of mental deficiency cannot be understood simply in terms of eugenics but must also be considered as part of the process of adjusting to democracy in the twentieth century.
