First published in 1990, this volume considers the question: is there any hope for economic recovery in Africa? Written by a team of leading development economists, the book takes a close look at the economic decline of Sub-Saharan Africa and provides a set of guidelines for promoting economic recovery. Stressing the need for greater co-operation between African states, the contributors outline the economic and social policies required to put this crisis-torn region back on the road to sustained development.

Service Life Prediction of Polymers and Plastics Exposed to Outdoor Weathering discusses plastics and polymers and their unique applications, from sealants used in construction, to polymer composites used in planes. While these materials are important enablers for advanced technologies, exposure to weather changes the very properties of plastics that make them so useful. This book reviews current research needs and provides a consensus roadmap of the scientific barriers to validated predictive models for the response of polymers and plastics to outdoor exposure. Despite extensive efforts over the past 20-30 years, testing of polymeric materials in accelerated or natural weathering conditions and the interpretation of the weathering results still require substantial improvements. This book represents the state-of-the-art in the prediction techniques available and in development. Engineers and materials scientists working in this field will be able to use the content of this book to assess the strengths and challenges of a range of different methods and approaches.

Polymaths of Islam analyzes the social and intellectual power of religious leaders who created a shared culture that integrated Central Asia, Iran, and India from the mid-eighteenth century through the early twentieth. James Pickett demonstrates that Islamic scholars were simultaneously mystics and administrators, judges and occultists, physicians and poets. This integrated understanding of the world of Islamic scholarship unlocks a different way of thinking about transregional exchange networks. Pickett reveals a Persian-language cultural sphere that transcended state boundaries and integrated a spectacularly vibrant Eurasia that is invisible from published sources alone. Through a high cultural complex that he terms the "Persian cosmopolis" or "Persianate sphere," Pickett argues that an intersection of diverse disciplines shaped geographical trajectories across and between political states. In Polymaths of Islam he paints a comprehensive, colorful, and often contradictory portrait of mosque and state in the age of empire.

Service Life Prediction of Polymers and Coatings: Enhanced Methods focuses on the cutting-edge science behind how plastic and polymer materials are modified by the effects of weathering, offering the latest advances in service life prediction methods. The chapters have been developed by experts based on their contributions as part of the 7th Service Life Prediction Meeting. The volume begins with the premise that it is possible to produce and design life predictions, also looking at how these predictions can be used. Subsequent chapters present new developments in service life prediction, examining the most important considerations in SLP design, timescales, and other major issues. The book also considers the current state of the field in terms of both accomplishments and areas that require significant research going forward. This is a highly valuable reference for engineers, designers, technicians, scientists and R&D professionals who are looking to develop materials, components or products for outdoor applications across a range of industries. The book also supports academic researchers, scientists and advanced students with an interest in service life, the effects of weathering, material degradation, failure analysis, or sustainability across the fields of plastics engineering, polymer science and materials science.
