Welding Deformation and Residual Stress Prevention, Second Edition provides readers with both fundamental theoretical knowledge about welding deformation and stress as well as unique computational approaches for predicting and mitigating the effects of deformation and residual stress on materials. This second edition has been updated to include new techniques and applications, outlining advanced finite element methods such as implicit scheme, explicit scheme, and hybrid scheme, and coupling analysis among thermal-metallurgy-mechanics. Non-destructive measurement methods for residual stresses are introduced, such as X-ray diffraction, the indentation technique, the neutron diffraction method, and various synchrotron X-ray diffraction techniques. Destructive measurement techniques are covered as well, such as block cutting for releasing residual stress, blind hole drilling, deep hole drilling, the slit cutting method, sectional contour method, and general inherent strain method. Various industrial applications of the material behavior and computational approaches are featured throughout.

This book is translated from the Chinese version published by Science Press, Beijing, China, in 2017. It was written for the Chern class in mathematics of Nankai University and has been used as the textbook for the course Abstract Algebra for this class for more than five years. It has also been adapted in abstract algebra courses in several other distinguished universities across China.The aim of this book is to introduce the fundamental theories of groups, rings, modules, and fields, and help readers set up a solid foundation for algebra theory. The topics of this book are carefully selected and clearly presented. This is an excellent mathematical exposition, well-suited as an advanced undergraduate textbook or for independent study. The book includes many new and concise proofs of classical theorems, along with plenty of basic as well as challenging exercises.

Cross-Scale Coupling and Energy Transfer in the Magnetosphere-Ionosphere-Thermosphere System provides a systematic understanding of Magnetosphere-Ionosphere-Thermosphere dynamics. Cross-scale coupling has become increasingly important in the Space Physics community. Although large-scale processes can specify the averaged state of the system reasonably well, they cannot accurately describe localized and rapidly varying structures in space in actual events. Such localized and variable structures can be as intense as the large-scale features. This book covers observations on quantifying coupling and energetics and simulation on evaluating impacts of cross-scale processes. It includes an in-depth review and summary of the current status of multi-scale coupling processes, fundamental physics, and concise illustrations and plots that are usable in tutorial presentations and classrooms. Organized by physical quantities in the system, Cross-Scale Coupling and Energy Transfer in the Magnetosphere-Ionosphere-Thermosphere System reviews recent advances in cross-scale coupling and energy transfer processes, making it an important resource for space physicists and researchers working on the magnetosphere, ionosphere, and thermosphere.

Water and Thermal Management of Proton Exchange Membrane Fuel Cells introduces the main research methods and latest advances in the water and thermal management of PEMFCs. The book introduces the transport mechanism of each component, including modeling methods at different scales, along with practical exercises. Topics include PEMFC fundamentals, working principles and transport mechanisms, characterization tests and diagnostic analysis, the simulation of multiphase transport and electrode kinetics, cell-scale modeling, stack-scale modeling, and system-scale modeling. This volume offers a practical handbook for researchers, students and engineers in the fields of proton exchange membrane fuel cells. Proton exchange membrane fuel cells (PEMFCs) are high-efficiency and low-emission electrochemical energy conversion devices. Inside the PEMFC complex, physical and chemical processes take place, such as electrochemical reaction, multiphase flow and heat transfer. This book explores these topics, and more.

This Open access book is a collection of interviews published by China News Service, a Beijing-based news agency, in its “West-East Talk” column. It has been divided into five sections: “Mutual Learning Among Civilizations,” “Hot Issues,” “About China,” “Sino-U.S. Relations” and “Cultural Collision”. The interviews are with more than 50 eminent scholars, scientists, politicians, authors, etc., from different parts of the world as well as China, who have an association with China and see the real China beyond the stereotypes. Besides current global issues, the book also covers Chinese culture, history as well as China-U.S. relations, described as one of the most important bilateral relationships in the world today. The book aims to build a platform for dialogue among different civilizations and appreciate the “harmony within diversity” of different cultures, especially of the East and West. We hope it will foster tolerance and rationality, dispelling the misconceptions about China in particular.

Nanomaterials for the Removal of Pollutants and Resource Reutilization presents the fundamental principles necessary for the application of nanomaterials in environmental pollution control and resource reutilization, also describing specific novel applications of environmentally functional nanomaterials. In addition to outlining the applications of nanomaterials for pollution control, the book highlights problems and offers solutions. This comprehensive resource will inspire the next generation of nanomaterial designers, providing a state-of-the-art review and exploration of emerging developments.

Nanohybrid and Nanoporous Materials for Aqueous Environmental Pollution Control gives a comprehensive treatment of fabrication methods and their application in environmental remediation, including adsorption, catalysis and signal transfer in pollutant detection. The design, fabrication and application of nanohybrid and nanoporous materials for environmental pollution control are described in detail, along with discussions on their synthesis, characterization, and applications in different aspects of pollutant treatment. Chapters introduce the design and synthesis of magnetic nanohybrid materials, advanced oxide process-photocatalytic degradation of environmental pollutants based on nanomaterials, and nanohybrids of iron based materials for reduction and oxidation of aqueous recalcitrant pollutant. Finally, challenges and suggestions in the application of nanomaterials for environmental pollution control are discussed, as is an analysis of the future perspective of nanomaterials for environmental application.

'Children have a unique curiosity for Nature and for this amazing planet we call home.' So writes HRH The Prince of Wales in his introduction to It's Up to Us: A Children's Terra Carta for Nature, People and Planet. Join His Royal Highness, author Christopher Lloyd and 33 amazing award-winning artists from around the world on a beautiful, lyrical and thought-provoking voyage through Nature, the threats we face and an action plan for the future. It's Up to Us is based on the Terra Carta, a roadmap to sustainability issued by His Royal Highness The Prince of Wales and his Sustainable Markets Initiative. More than 400 corporations have already signed on, agreeing to put the health of Nature, People & Planet at the heart of their activities. Now it's up to all of us to make sure our leaders keep their promises. This book has been developed in partnership with The Prince's Foundation, a charity established by HRH The Prince of Wales to demonstrate how Nature can be put at the heart of human activities. Half of all the proceeds from sales will go directly to the work of the charity, based at Dumfries House in Scotland. Printed in the UK on recycled FSC paper with vegetable inks, and all the carbon impacts of the production have been offset through The World Land Trust and other programmes to reduce carbon emissions around the world.
