Distribution and Transformation of Nutrients in Large-scale Lakes and Reservoirs

The Three Gorges Reservoir

By: Zhenyao Shen,Junfeng Niu,Xiying Wang,Hongyuan Wang,Xin Zhao

Distribution and Transformation of Nutrients and Eutrophication in Large-scale Lakes and Reservoirs: The Three Gorges Reservoir" presents key findings on early eutrophication in large-scale lakes and reservoirs, providing readers with an overview of lake management problems and the tools that can be applied to solve them. The broad spectrum of available tools is presented in detail, including environmental technological methods, ecotechnological methods and the application of models to determine the best management strategy. The book is intended for environmental engineers and researchers in the fields of environmental science and ecological chemistry. Professor Zhenyao Shen, Professor Junfeng Niu and Associate Professor Ying Wang work at the School of Environment, Beijing Normal University, China. Dr. Hongyuan Wang works at Chinese Academy of Agricultural Sciences, China. Dr. Xin Zhao works at Changjiang River Scientific Research Institute, China.

Evidence-based Clinical Chinese Medicine - Volume 16: Atopic Dermatitis

By: Meaghan Coyle,Junfeng Liu

The authors start the book with overviews of the understanding and management of atopic dermatitis in conventional and Chinese medicine. They then review how atopic dermatitis was treated with herbal medicine and other Chinese medicine therapies in past eras, and highlight the treatments that continue to be used in contemporary clinical practice.The authors use evidence-based medicine principles and scientific techniques to review the current state of evidence from clinical studies of Chinese herbal medicine, acupuncture, and combinations of these therapies. Attention is given to studies evaluating these therapies used as an adjunct to conventional treatments. The authors summarise the results of analyses of clinical outcomes and discuss their implications for clinical practice of Chinese medicine and for future research.This book will inform clinicians and students of Chinese and integrative medicine of the current state of evidence from contemporary and traditional sources. Clinicians can refer to the herbal formulas and acupuncture treatments described in this book to make evidence-based decisions in patient care.The following features mark the importance of this book in the field:

Safety Theory and Control Technology of High-Speed Train Operation

By: Junfeng Wang

Safety Theory and Technology of High-Speed Train Operation puts forward solutions for train dispatching and signal control. Frequent railway incidents have threatened the safety of rail transport. In 2013, more than 12 trains collided. In the same year, a Spanish train derailed due to speed, and two of China's high-speed trains collided. In 2016, Germany and Italy both experienced serious train collisions. Global railway security is essential. Many accidents are caused by train dispatching errors and signal system failure. Chinese high-speed railway has developed very quickly and at a very large scale. However, many issues reagrding safety has not been addressed. This book considers the issue from the perspective of a system. A train operation control system structure is put forward in order to ensure safety. Five key technologies (namely system-level fail-safe, parallel monitoring, completeness of train control data, data sharing and fusion and prevention of common errors in monitoring), are proposed. In order to prevent collision, over-speed, derailment, and rear-end collision accidents, the concept and corresponding parallel monitoring technology of five core control items (train route, speed, tracking interval, temporary speed limit, train running state) is proposed. - Puts forward solutions for train dispatching and signal control - Views high-speed train safety and technology from a systems-theory perspective - Describes five key technologies to ensure safety - Proposes five parallel monitoring technologies to prevent collision, over-speed, derailment and rear-end collision incidents - Considers the very quick and large-scale development of Chinese high-speed rail

The Chemistry of Ynamides

Development, Syntheses, and Applications in Organic Synthesis

By: Gwilherm Evano,Junfeng Zhao

Ynamides contain a triple bond directly connected to a nitrogen atom that bears an electron-withdrawing group. They represent an especially useful and emerging class of reagents, notably because of their strongly polarized triple bond, which enables the development of unique chemical transformations. While they were discovered by Viehe in 1972, their chemistry has remained little investigated and the renaissance of ynamide chemistry started at the dawn of the 20th century with the development of efficient methods for their synthesis. Since then, ynamide chemistry has developed at a remarkably high rate, notably in the past 20 years. Although there are several reviews on ynamide chemistry, most of them are out of date or only focus on special aspects of ynamide chemistry and there is no book about ynamide chemistry yet. Thus, a comprehensive book on ynamide chemistry would be timely and is highly needed. This book covers all aspects of ynamide chemistry, including their discovery, their syntheses, their application in heterocyclic chemistry, natural product synthesis, and organometallic chemistry, and their use as coupling reagents. It provides a systematic and comprehensive overview on ynamide chemistry for the researchers in this field, general readers interested in synthesis, and those who want to enter this field and need a comprehensive and up-to-date overview. Undoubtedly, this book will play a key role in connecting the past with the future to further foster the development of ynamide chemistry.
