Book Description
In recent years remarkable progress has been made in the development of materials for ultrasonic transducers. There is a continuing trend towards increasingly higher frequency ranges for the application of ultrasonic trans ducers in modern technology. The progress in this area has been especially rapid and articles and papers on the subject are scattered over numerous technical and scientific journals in this country and abroad. Although good books have appeared on ultrasonics in general and ultrasonic transducers in particular in which, for obvious reasons, materials play an important part, no comprehensive treatise is available that represents the state-of-the-art on modern ultrasonic transducer materials. This book intends to fill a need for a thorough review of the subject. Not all materials are covered of which, theoretically, ultrasonic trans ducers could be made but those that are or may be of technical impor tance and which have inherent electro acoustic transducer properties, i.e., materials that are either magnetostrictive, electrostrictive, or piezoelectric. The book has been devided into three parts which somewhat reflect the historic development of ultrasonic transducer materials for important tech nical application. Chapter 1 deals with magnetostrictive materials, magnetostrictive met als and their alloys, and magnetostrictive ferrites (polycrystalline ceramics). The metals are useful especially in cases where ruggednes of the transducers are of overriding importance and in the lower ultrasonic frequency range.

Book Description
This volume looks beyond the distribution of income by examining the assets, debts, and net worth of individuals and households to create a global picture of wealth, its distribution and concentration. Unlike previous studies, this study includes material on a number of transition and developing countries as well as high income OECD countries.

Book Description
Large igneous provinces (LIPs) are intraplate magmatic events, involving volumes of mainly mafic magma upwards of 100,000 km3, and often above 1 million km3. They are linked to continental break-up, global environmental catastrophes, regional uplift and a variety of ore deposit types. In this up-to-date, fascinating book, leading expert Richard E. Ernst explores all aspects of LIPs, beginning by introducing their definition and essential characteristics. Topics covered include continental and oceanic LIPs; their origins, structures, and geochemistry; geological and environmental effects; association with silicic, carbonatite and kimberlite magmatism; and analogues of LIPs in the Archean, and on other planets. The book concludes with an assessment of LIPs' influence on natural resources such as mineral deposits, petroleum and aquifers. This is a one-stop resource for researchers and graduate students in a wide range of disciplines, including tectonics, igneous petrology, geochemistry, geophysics, Earth history, and planetary geology, and for mining industry professionals.

Book Description
The term “vulnerable realism” can imply two different understandings: one presenting weak realism as incomplete, and mixed with other literary styles; the other bringing realistic vulnerable experience into narration. The second is the key concern of this work, though it does not exclude the first, as it asks questions about realism as such, entering into a polemic with the tradition of literary realism. Realism, then, is not primarily understood as a narrative style, but as a narration that tests the probability of nonhuman vulnerable experience and makes it real. The book consists of three parts. The first presents examples of how realism has been redefined in trauma studies and how it may refer to animal experience. The second explores what is added to the narrative by literature, including the animal perspective (the zoonarrative) and how it is conducted (zoocriticism). The third analyses cultural texts, such as painting, circuses, and memorials, which realistically generate animal vulnerability and provide non-anthropocentric frameworks, anchoring our knowledge in the experience of fragile historical reality.
