A major goal of materials science is to create new engineering materials and optimize their cost and performance. Understanding how adjacent materials behave at their borders is an essential part of this process. Grain boundaries are the longest-known crystal defects, but although they were discovered in the mid-eighteenth century, until quite recently, we did not understand them very well. Even now, scientists are still searching for the best ways to comprehensively characterize a material’s microstructure—and accurately predict its evolution and behavior. Fills the gap between the physics of grain boundary motion and its engineering practicalityLike the popular first edition, Grain Boundary Migration in Metals: Thermodynamics, Kinetics, Applications, Second Edition focuses extensively on the thermodynamics, kinetics, and applications involved with individual grain boundary migration in metals. However, this new volume adds a decade’s worth of new developments in research and methods. It offers an up-to-date overview of current knowledge of the grain boundary migration process, and it details how migration influences microstructural evolution, including the recrystallization process and the creation of new materials. The authors rely on well-defined geometry and crystallography to address key topics such as grain growth, textures, and the properties and behavior of grain boundaries, particularly the nonlinear interaction of boundary elements. This invaluable second edition: Covers the latest techniques and computer simulations used in the study of single-grain boundary motion and grain boundary systems with junctions Provides the latest experimental data of grain boundary free volume measurements and offers the first measurements of grain boundary junction line tension Includes new problems with solutions As a solid foundation on which you can build your understanding of the migration phenomenon, this book should be required reading for researchers in areas such as interface physics and materials science of microstructure evolution and property control. It will also be vastly useful to any professional engaged in metals production and/or the heat treatment of metals and alloys.

Welcome to the uncertain world of "Radio 2.0"—where podcasts, mobile streaming, and huge music databases are the new reality, as are tweeting deejays and Apple's Siri serving as music announcer—and understand the exciting status this medium has, and will continue to have, in our digitally inclined society.How did popular radio in past decades—from President Franklin D. Roosevelt's "Fireside Chats" in the 1930s through Top 40 music and Rush Limbaugh's talk radio empire—shape American society? How did devices and systems like the iPhone, Pandora, and YouTube turn the radio industry upside-down? Does radio still have a future, and if so, what will we want it to look like?Radio 2.0: Uploading the First Broadcast Medium covers the history and evolution of Internet radio, explaining what came before, where Internet radio came from, and where it is likely headed. It also gives readers a frame of reference by describing radio from its introduction to American audiences in the 1920s—a medium that brought people together through a common experience of the same broadcast—and shows how technologies like digital music and streaming music services put into question the very definition of "radio." By examining new radio and media technologies, the book explores an important societal trend: the shift of media toward individualized or personalized forms of consumption.

This book is the first comparative study of three ceramic ware groups found at Ephesos (modern day Turkey): Appliqué Ware, White-grounded ware and Pergamene Sigillata. Until now they were considered to be products made in and imported from Pergamon, but intensive archaeometrical analysis demonstrate that they were produced locally.

Urban Religion is an emerging research field cutting across various social science disciplines, all of them dealing with “lived religion” in contemporary and (mainly) global cities. It describes the reciprocal formation and mutual influence of religion and urbanity in both their material and ideational dimensions. However, this approach, if duly historicized, can be also fruitfully applied to antiquity. Aim of the volume is the analysis of the entanglement of religious communication and city life during an arc of time that is characterised by dramatic and even contradicting developments. Bringing together textual analyses and archaelogical case studies in a comparative perspective, the volume zooms in on the historical context of the advanced imperial and late antique Mediterranean space (2nd–8th centuries CE).

Ancient religions are definitely complex systems of gods, which resist our understanding. Divine names provide fundamental keys to gain access to the multiples ways gods were conceived, characterized, and organized. Among the names given to the gods many of them refer to spaces: cities, landscapes, sanctuaries, houses, cosmic elements. They reflect mental maps which need to be explored in order to gain new knowledge on both the structure of the pantheons and the human agency in the cultic dimension. By considering the intersection between naming and mapping, this book opens up new perspectives on how tradition and innovation, appropriation and creation play a role in the making of polytheistic and monotheistic religions.Far from being confined to sanctuaries, in fact, gods dwell in human environments in multiple ways. They move into imaginary spaces and explore the cosmos. By proposing a new and interdiciplinary angle of approach, which involves texts, images, spatial and archeaeological data, this book sheds light on ritual practices and representations of gods in the whole Mediterranean, from Italy to Mesopotamia, from Greece to North Africa and Egypt. Names and spaces enable to better define, differentiate, and connect gods.
