With the phenomenal development of electromagnetic wave communication devices and stealth technology, electromagnetic wave absorbing materials have been attracting attention as antielectromagnetic interference slabs, stealth materials, self-concealing technology, and microwave darkrooms. This book starts with the fundamental theory of electromagnetic wave absorption in loss medium space, followed by a discussion of different microwave absorbents, such as manganese dioxide, iron-based composite powder, conductive polyaniline, barium titanate powder, and manganese nitride. Then, structural absorbing materials are explored, including multilayer materials, new discrete absorbers, microwave absorption coatings, cement-based materials, and structural pyramid materials. Many of the graphics demonstrate not only the principles of physics and experimental results but also the methodology of computing. The book will be useful for graduate students of materials science and engineering, physics, chemistry, and electrical and electronic engineering; researchers in the fields of electromagnetic functional materials and nanoscience; and engineers in the fields of electromagnetic compatibility and stealth design.
This book reveals the latest research findings and innovations in electromagnetic wave absorption and shielding by exploring the design and application of absorbent materials, the optimization of shielding structures and the improvement of testing and evaluation methods. From conductive materials to magnetic materials, and composite materials to nanomaterials, Electromagnetic Wave Absorption and Shielding Materials details the characteristics and advantages of various absorbent materials and explains their applications in electromagnetic wave absorption and shielding. It then introduces the different methods of electromagnetic shielding, including structural shielding and material shielding. The book also studies experimental and testing techniques, including measurement methods and evaluation criteria for electromagnetic wave absorption performance. The book will be of interest to researchers and graduate students in electromagnetic compatibility, materials science and engineering.
This unique book provides an up-to-date overview of the concepts behind lead-free soldering techniques. Readers will find a description of the physical and mechanical properties of lead-free solders, in addition to lead-free electronics and solder alloys.

This book has explored in depth the beliefs and practices of foreign language teachers regarding global awareness in the context of a Chinese senior high school. This book defines global awareness as a combination of global knowledge, global attitudes, and global skills for a global citizen to act from the local community to the global community. By analysing qualitative data such as classroom observations, interviews and focus groups with language teachers and linking these findings to language education policy and practice in China, this book has explored how English language teachers teach English language, intercultural communicative competence and global awareness in China. This book will be of interest to researchers, language teachers and students in the fields of language education and intercultural communication. It also provides a readable overview for those new to the field of ICC and global citizenship education.
Drawing on cultural trauma theory, this book investigates how collective memory of the Nanjing Massacre is fashioned in China and how the mass media, political power and public praxis jointly shape the politics and culture of memory in contemporary China. Allowing for the dimensions of history and different mediating spaces, the authors first conduct textual analysis of news reports from traditional media since the event took place, revealing that the significance of the Massacre was initially portrayed as a local incident before its construction as a national trauma and finally a collective memory. In a study of physical and online memorial spaces, including the Memorial Hall, commemorative activities on the Internet and new media platforms, the book unveils the production and reproduction of trauma narratives as well as how these narratives have been challenged. The final part further studies the interactions between media and other institutional settings while exploring issues of global memory and reconciliation in East Asia. The title will be an essential read for anyone interested in memory studies, media and communication, and particularly the collective memory of the Nanjing Massacre.
A contemporary evaluation of switching power design methods with real world applications • Written by a leading author renowned in his field • Focuses on switching power supply design, manufacture and debugging • Switching power supplies have relevance for contemporary applications including mobile phone chargers, laptops and PCs • Based on the authors' successful "Switching Power Optimized Design 2nd Edition" (in Chinese) • Highly illustrated with design examples of real world applications
The foundation for targeted therapy of cancers driven by members of the ErbB oncoprotein family was established initially by the demonstration that ectodomain binding monoclonal antibodies (mAb) could disable the protein kinase encoded by the HER2/neu oncogene. Homomeric and heteromeric erbB kinases play critical roles in the development of cancer and in the spread of early lesions. In particular, antibodies targeting the p185erbB2/neu receptor provide major clinical benefits in the treatment of breast cancer and also stomach cancer. As suggested by our study with oncogenic neu transgenic mice, anti-p185erbB2/neu antibodies are also effective in preventing the tissue hyperplasia that precedes tumorigenesis, tumor growth and the dissemination of ErbB2/neu kinase-positive cells into other tissues. As a therapeutic principle, “reversion of phenotype” for established tumors and “prevention” of tumorigenesis and spread can explain the basis for the benefits invoked by therapeutic and adjuvant therapies for breast cancer patients after cancers are surgically removed. These emerging principles being enlightened by ongoing studies of monoclonal antibody therapy will continue to provide guidance for the development of new targeted therapies for resistant tumors that arise after treatment.
