Separation and characterization of materials is an essential step in the advancement of science and technology. The need for separation and characterization could arise from wishes to obtain purified samples with less contaminants, requirements for quality control of materials for downstream applications, or needs to identify structures and conformations of active species present in the applications. The types of materials encountered in applications are diverse,from synthetic polymers and biological derived biopolymers to micro or submicro particles and various conjugated or self-assembled nanomaterials. This makes the task of separation and characterization challenging. There is no one-size-fits-all approach. Scientists, whether working in academia or inindustries, are constantly facing new challenges. Communication between scientists is essential for keeping each other updated on developments in the field. This was the motivation for organizing the symposium on "Recent Progress in Separation of Macromolecules and Particulates" at the 2017 Spring National American Chemical Society (ACS) Meeting in San Francisco. Symposiums based on such a theme have been organized several times in ACS meetings as well as in other settings, but no suchsymposium books have been published. Hence, the editors decided to put together this symposium book, based on the talks presented at the symposium, in the hope that knowledge shared at the meeting can be shared more broadly within the community and beyond.

Based on the fieldwork carried out at two elementary schools, Merits School and Pioneer School, in northeastern China, the monograph details how local schools enacted the New Mathematics Curriculum Reform that was launched in early 2000.The trajectory of the reform implementation at each school was plotted out. Both schools resorted to a long-standing quality control mechanism, i.e., teaching norms, to operationalize the reform ideas. The mechanism functioned by placing teachers under measurable supervision and evaluation aligned with the reform. The schools responded to the reform following school people’s raising practical concerns, as well as the established school culture. Merits School arrived at a "two-faced strategy" to cope with the reform. Pioneer School managed to maintain a balance between promoting reform pedagogy and maintaining good test rankings. Both schools marginally involved parents in the implementation of the reform. This study suggests that to achieve success, reformers need to place equal emphasis on the transformation of teachers as well as local policymakers.This book enriches the existing literature on the implementation of mathematics curriculum reform at the school level and brings insights into the schools’ implementation decisions, which will appeal to policymakers, curriculum researchers and administrators.

This book features selected proceedings from the "2024 International Conference on Geotechnics and Hydraulic Structure," focusing on Geotechnical Engineering and Intelligent Disaster Prediction.

This book compiles research findings related to geotechnical engineering and urban underground space, providing readers with targeted research experience and case studies. Geotechnical engineering, which involves the foundation safety of infrastructure and structures, is an important fundamental research area in civil engineering. It provides crucial basic data for intelligent disaster prediction. Geotechnical engineers gather extensive information about rock and soil properties through geological surveys and soil sample tests. This information is particularly important for addressing issues related to geotechnical loadings and structural safety in complex environments, directly impacting the proper use and safety of engineering projects. Urban underground space has been continuously developing as above-ground space resources become increasingly scarce. Especially in major cities and large cities in developed countries, the construction of underground space remains an important part of urban development. Unlike above-ground construction, the development and construction of underground space require more attention to geotechnical engineering and soil mechanics loadings, particularly in the early stages of exploration, structural support during construction, and load monitoring in the use stages. If structural damage or collapse occurs in urban underground space, it not only causes the collapse of the underground space itself but may also lead to a chain reaction of catastrophic collapses or structural damage to above-ground buildings or structures in the corresponding area. Therefore, the structure and design of urban underground space are equally important. This book includes several papers from the 2025 International Conference on Geotechnics and Hydraulic Structure, discussing topics related to geotechnical engineering and urban underground space. Topics include, but are not limited to, geotechnical slope and soil mechanics analysis, tunneling and urban underground space engineering, and water-soil (rock) foundation-structure interaction. Our goal is to share the latest research findings with geotechnical engineers worldwide and provide more solutions to complex engineering challenges.

The subject of electronic and ionic materials has grown rapidly over the last 20 to 30 years. The application of these materials has had a significant impact on modern industries and on society in general. The subject is so important that no electrical engineering, materials science and engineering, applied physics or chemistry degree would be complete without it.This valuable textbook is aimed at engineering and technology undergraduates who have a background in physics or chemistry only at first year level. It provides a basic understanding of the properties and uses of a wide range of electrically and ionically conducting materials. It is not intended to be a solid state physics or chemistry book, and so the mathematics is kept to a minimum. However, it is intended to give the student an overview of a wide range of electrical materials and their uses in today's society.

The aim of this handbook is to provide a comprehensive summary of sensing and measurement in precision manufacturing, which is essential for process and quality control. The importance of precision sensing and measurements lies not only in the ability to distinguish whether the manufactured part meets the assigned tolerances through inspection but also, in many cases, reduce the deviation of the manufactured part from the designed values through improvement of the process or compensation manufacturing based on the sensing and measurement results. The information provided in the book will be of interest to industrial practitioners and researchers in the field of precision manufacturing sensing and measurements.This volume is part of a multi-volume handbook series that covers a comprehensive range of scientific and technological matters in ‘Precision Manufacturing’, for more information please view this link- https://www.springer.com/series/15575.

Social media platforms have been ubiquitously used in our daily lives and are steadily transforming the ways people communicate, socialize and conduct business. However, the growing popularity of social media adversely leads to wild spread of unreliable information. This in turn inevitably creates serious pollution problem of the global social media environment, which is harmful against humanity. For example, President Donald Trump used social media strategically to win in the 2016 USA Presidential Election. But it was found that many messages he delivered over social media were unproven, if not untrue. This problem must be prevented at all cost and as soon as possible. Thus, analysis of social media content is a pressing issue. It is a timely and important research subject worldwide. However, the short and informal nature of social media messages renders conventional content analysis, which is based on natural language processing (NLP), ineffective. This volume consists of a collection of highly relevant scientific articles published by the authors in different international conferences and journals, and is divided into three distinct parts: (I) search and filtering; (II) opinion and sentiment analysis; and (III) event detection and summarization. This book presents the latest advances in NLP technologies for social media content analysis, especially content on microblogging platforms such as Twitter and Weibo.
