There has been a great advance in the understanding of processes of meta­ morphism and of metamorphic rocks since the last edition of this book appeared. Methods for determining temperatures and pressures have become almost routine, and there is a wide appreciation that there is not a single temperature and pressure of metamorphism, but that rocks may preserve, in their minerals, chemistry and textures, traces of their history of burial, heating, deformation and permeation by fluids. However, this excit­ ing new knowledge is still often difficult for non-specialists to understand, and this book, like the first edition, aims at enlightenment. I have concen­ trated on the interpretation of the plate tectonic settings of metamorphism, rather than following a geochemical approach. Although there is an impress­ ive degree of agreement between the two, I believe that attempting to discover the tectonic conditions accompanying rock recrystallization will more readily arouse the interest of the beginner. I have used a series of case histories, as in the first edition, drawing on my own direct experience as far as possible. This m

I have used a series of case histories, as in the first edition, drawing on my own direct experience as far as possible. This m~ns that some subjects are treated in more detail than others, and many important topics are barely mentioned at all. It also means that general concepts appear in a rather haphazard order in the text. To help my readers, I have provided a glossary of definitions of terms used in the book, which are indicated in bold type in the text.

This book explores and analyzes how the Arab Spring has affected the political and economic relationships between the West, the BRICs (Brazil, Russia, India, China, and South Africa) and the MENA (Middle Eastern and North African states). It locates continuity and change in these relations within the broader context of democratization, energy, security, arms relationships, and the shift towards a multi-polar system. Each chapter charts a history of ideological engagement, which has generally given way to more pragmatic energy, economic, and security interests, and defines and analyzes the fundamental and emerging factors that shape foreign policy. The volume pays special attention to the UN Security Council authorization of "all necessary measures" against Qaddafi's Libya and the subsequent deadlock in getting China and Russia to pass further Resolutions for intervention in Syria.

Advances in Structure Research by Diffraction Methods reviews advances in the use of diffraction methods in structure research. Topics covered include the dynamical theory of X-ray diffraction, with emphasis on Ewald waves in theory and experiment; dynamical theory of electron diffraction; small angle scattering; and molecular packing. This book is comprised of four chapters and begins with an overview of the dynamical theory of X-ray diffraction, especially in terms of how it explains all the absorption and propagation properties of X-rays at the Bragg setting in a perfect crystal. The next chapter describes the dynamical theory of electron diffraction, paying particular attention to unconventional structure analysis in connection with the problems of absorption. The most important features of the background of small angle analysis are then examined, and some examples showing the direct analysis of small angle scattering (sometimes in combination with wide angle scattering) are provided. The last chapter deals with crystals built from molecules and their peculiar geometrical features. The principle of close packing of molecules in an organic crystal is also described, along with lattice dynamics, hydrogen bonds in crystals, and the rotational crystalline state. This monograph will be a useful resource for practitioners and researchers in physics and crystallography.

Advances in Structure Research by Diffraction Methods: Volume 5 presents discussions on application of diffraction methods in structure research. The book provides the aspects of structure research using various diffraction methods. The text contains 2 chapters. Chapter 1 reviews the general theory and experimental methods used in the study of all types of amorphous solid, by both X-ray and neutron diffraction, and the detailed bibliography of work on inorganic glasses. The second chapter discusses electron diffraction, one of the major methods of determining the structures of molecules in the gas phase. Chemists and molecular physicists will find the book a great source of information.
