Analytical ultracentrifugation (AUC) is a powerful method for the characterization of polymers, biopolymers, polyelectrolytes, nanoparticles, dispersions, and other colloidal systems. The method is able to determine the molar mass, the particle size, the particle density and interaction parameters like virial coefficients and association constants. Because AUC is also a fractionation method, the determination of the molar mass distribution, the particle size distribution, and the particle density distribution is possible. A special technique, the density gradient method, allows fractionating heterogeneous samples according to their chemical nature that means being able to detect chemical heterogeneity. The book is divided into chapters concerning instrumentation, sedimentation velocity runs, density gradient runs, application examples and future developments. In particular, the detailed application chapter demonstrates the versatility and power of AUC by means of many interesting and important industrial examples. Thus the book concentrates on practical aspects rather than details of centrifugation theory.

Both authors have many years of experience in an industrial AUC research laboratory of a world leading chemical company.

This book examines Western foreign policy towards the Middle East, and the extent to which the promotion of democracy has been in conflict with, or supported by, other goals (geo-strategic, economic, and cultural) in the policies of the major actors towards the Middle East. Does the Arab Spring provide a new opening for cooperation with the region? Contributions are offered by scholars with research interests in Middle Eastern politics, and by those analysing the policies and interests of external actors. Against the backdrop of the recent 'War on Terror', the comparative and interdisciplinary outlook of the book will offer the opportunity for much needed intellectual exchanges between political scientists, contemporary historians, and international relations scholars from Europe, North America and the Middle East. Since it coincides with and/or follows the final phases of US and British withdrawal from Iraq and Afghanistan, this book will be highly relevant to both academics and policy-makers in the UK and abroad, making a significant contribution not only to the scholarly investigation of Western foreign policies, but also to the study of the Middle East in general. This book was originally published as a special issue of the Cambridge Review of International Affairs.

This volume includes 19 contributions to the 13th International Symposium on Analytical Ultracentrifugation which took place at the university of Osnabruck on March 6th and 7th, 2003. The contributions from leading scientists cover a broad spectrum of topics concerning: Technical Methods, Data Analysis, Innovations; Polymers, Colloids, Supramolecular Systems; Biological and Interaction Systems; Hydrodynamics and Modelling.

Due to the increasing significance of Analytical Ultracentrifugation for both scientific and technical applications, this book will be an essential source of information with respect to recent developments and results related to this important analytical method."
