This Open Access book introduces readers to the regional geology of Hanggai, Xianxia and Chuancun, the area between China's northern Zhejiang Province and southern Anhui Province and explores the strata, magmatic rocks and tectonic structures in 1:50,000 scale geological maps. Based on studies of multiple stratigraphic divisions, the standard stratigraphic section of the upper Ordovician Hirnantian in the lower Yangtze region is established, revealing for the first time numerous "Burgess Shale-type" sponge fossils in Hirnantian strata and identifying 10 grapholite fossil belts and various fossil categories, including chitin, trilobites, gastropods, brachiopods, and cephalopods. Moreover, the book identifies for the first time Late Ordovician volcanic events in northern Zhejiang province. The work represents a major contribution to research on Paleozoic strata in the Lower Yangtze region, and sheds new light on understanding the Hirnantian glacial event and biological extinction event in South China by providing a high-precision time scale. In addition, the book opens an important avenue for future research on sponge evolution after the Cambrian life explosion. As such, it offers a unique and valuable asset for researchers and graduate students alike.
This book addresses anti-fatigue manufacturing, analysis and test verification technologies for typical aircraft structures, including fastening holes, shot peening plates, different types of joints and wing boxes. Offering concrete solutions to practical problems in aircraft engineering, it will benefit researchers and engineers in the fields of Aerospace Technology and Astronautics.
This book, with a focus on the establishment of urban public security risk prevention and control system, carries out a comprehensive review and a comparative study of its development. It provides a systematical analysis to the inevitable security issues in the process of urban development and conducts an in-depth discussion on the background of times featuring heightened security risks as well as the main sources of current urban public security risks. In addition to analyzing the inner structure and development motivations, this book further summarizes the inner mechanism for the effective operation of urban risk prevention and control system and elaborates on the reasons why grassroots governance plays a vital role throughout the whole process. Moreover, this book sheds some light on the future development of urban security risk prevention and control system. Centering on the frontiers of urban public security risk prevention and control, this book probes into the important issues in establishing an effective urban public security risk prevention and control system by combining theory and practice. As a result, it is highly recommended for scholars, government officials, and practitioners in the field of emergency management.

The energy demands of contemporary society mandate the urgent development and commercialisation of a 'post-Li-ion battery'. Metal anodes are an important piece of this puzzle. This research and reference text discusses the role of metal electrodes in batteries in detail. Introducing the fundamental theoretical properties of metal anodes, the book surveys the history and prospects of the field, covering a wide range of metals, including Li, Na, K, Mg, Al, Zn, Ge, Sn, Sb and Bi. The first book of its kind to offer a comprehensive survey of the field, 'Metal Electrodes and Battery Technologies' facilitates engagement with the latest research and future challenges concerning the role of metals in the development of high-capacity batteries.
