Challenges of Power Engineering and Environment
This book is the proceedings of the International Conference on Power Engineering-2007. The fields of this book include power engineering and relevant environmental issues. The recent technological advances in power engineering and related areas are introduced. This book is valuable for researchers, engineers and students majoring in power engineering.
Gel Chemistry
This book covers various molecular, metal-organic, dynamic covalent, polymer and other gels, focusing on their driving interactions, structures and properties. It consists of six chapters demonstrating interesting examples of these gels, classified by the type of driving interaction, and also discusses the effect of these interactions on the gels’ structures and properties. The book offers an interesting and useful guide for a broad readership in various fields of chemical and materials science.
Recent Advances in Durability Improvement and Low-Carbon Strategy of Engineering Materials and Structures
Global warming, caused by a significant increase in the concentration of greenhouse gases (GHGs) such as CO2, has become a concern all over the world. The whole process carbon emissions of the civil engineering industry account for nearly 40% of global energy and process-related CO2 emissions, more than half of which come from the process of producing, using, constructing and dismantling in civil engineering materials and structures, resulting in the embodied carbon emissions. With the acceleration of global warming, warmer and uncertain climates will make engineering materials and structures subject to more severe environmental conditions. A series of durability issues will occur more frequently, such as the significant variations of humidity in air, the chloride-induced corrosion caused by the severe chloride ingress, concrete cracking caused by the expansion of rusts, and more severe carbonation of concrete structures due to the increase in CO2 concentration. The adoption of positive measures to address climate change has become a global consensus, as global warming has led to serious threats and challenges to the survival and development of humankind.
Bupleurum Species
The prominence of the Bupleurum species cannot be overstated. Across China and Japan, it serves as a main or supplementary ingredient in over two thirds of traditional medications. For over 2000 years, it has been used to treat fevers, intestinal maladies, malaria, and countless other afflictions. Modern research indicates that it may possess anti-
Letters from Home to Wuhan
Letters from Home to Wuhan By: Compiled by Zhao Nianmin, Li Haiyan and Lan Chuanbin; Translated by Sun Hongshan Ever since the People’s Republic of China was founded in 1949, the coronavirus disease (COVID-19) is the most serious public health emergency. Then the virus spread rapidly in this country, inspiring terror in people. To ward off a greater calamity, 1,775 doctors and nurses in 12 batches from Shandong went to the epidemic-stricken Hubei at the call of duty. Brave and professionally dedicated, they have completed their work with great success: None of them were infected, none of their patients died, and none of the cured cases turned positive again. At the front line the 1,775 medical workers are armored fighters, but at home they are also sons, daughters, wives, husbands or parents. With a quick change of role, they vent in letters their conflicting feelings of pride and horror, of joys and sorrows, and of affection for family and devotion to duty. So, for this spring, letter has been the most heartwarming, the most acute, the most candid, and the most delicate form to express feelings.
