This informative volume provides comprehensive knowledge on various aspects of wastewater resource management from the point of process sustainability and resource recovery. This authoritative compendium is crucial for developing resource-efficient and sustainable wastewater treatment technologies and management strategies for both small (decentralized) and large (centralized) communities. Traditional wastewater systems have become increasingly energy-consuming and cost-intensive while also not meeting the increasing standards for nutrient removal and sustainable development. This book incorporates the latest developments in pollutant removal and resource recovery schemes in wastewater treatment. It highlights advances that have been made in microbiological processes; design of treatment methods; process configurations; energy conservation and efficiency improvement schemes; nutrient removal; recovery, reclamation, and recycling; beneficial uses of wastewater; and bioenergy and biochemical production from wastewater and sludge streams. Waste-to-energy technologies, especially wastewater treatment as a potential biofuel energy alternative through bioelectrochemical and other processes, are also discussed in this book.

The numerical, discrete element, Discontinuous Deformation Analysis (DDA) method was developed by Dr. Gen-hua Shi while he was working at the University of California, Berkeley, under the supervision of Prof. Richard E. Goodman in the late 1980s. Two-dimensional DDA was published in 1993 and three-dimensional DDA in 2001. Since its publication DDA has been verified, validated and applied in numerous studies worldwide and is now considered a powerful and robust method to address both static and dynamic engineering problems in discontinuous rock masses. In this book Yossef H. Hatzor and Guowei Ma, co-chairs of the International Society for Rock Mechanics (ISRM) Commission on DDA, join Dr. Shi in authoring a monograph that presents the state of the art in DDA research. A comprehensive discussion of DDA development since its publication is provided in Chapter 1, followed by concise reviews of 2D and 3D DDA in chapters 2 and 3. Procedures to select geological and numerical input parameters for DDA are discussed in Chapter 4, and DDA validation and verification is presented in Chapter 5. Applications of DDA in underground and rock slope engineering projects are discussed in chapters 6 and 7. In Chapter 8 the novel contact theory recently developed by Dr. Shi is published in its complete form, for the first time. This book is published within the framework of the ISRM Book Series and is the contribution of the ISRM DDA Commission to the international rock mechanics community.

Beyond Recycling critically explores unasked questions around recycling and its prominent position in contemporary thinking about sustainability. It examines and challenges assumptions about why we appear to have so wholeheartedly committed to recycling as a cultural project. Recycling has become a commonplace notion and widespread practice. Yet its social, cultural and even environmental value has not been considered carefully enough. This book considers recycling as a contemporary cultural idea related to - but not wholly defined by - our response to material waste. It seeks to reclaim recycling from the environmentalists and waste management specialists, to explore the role it plays in wider contemporary discourse. As we become increasingly satiated, and in many cases sickened, by the excesses of modern consumerism, we are rethinking our relationship with the physical stuff that fills our lives. Dissatisfied with empty materialism, we seek new ways to reuse our material culture. Recycling, turning something considered to be waste into something with renewed value, is our primary collective response to the problems arising from consumption; and it is ripe for critical examination. Beyond Recycling is a fascinating read for conscious consumers and students in the creative arts, design, cultural studies, sustainability and environmental studies.

In the past 13 years since the publication of Longwall Mining, 2nd edition in 2006, although there have been no major changes in longwall mining technology and operations, many incremental developments in the whole system as well as various subsystems of the existing longwall mining operational technologies as detailed in the 2nd edition have been added to this edition. Major developments are automation, and health and safety technology, as well as equipment reliability, thereby greatly increasing productivity and cutting cost. In particular, the longwall system can now run automatically cut by cut forever without operators' intervention provided that the geology allows it. Other health and safety features such as LASC, personal proximity detection, color lighting, automatic shield water sprays and remote shearer control are fully operational. There are more than 7000 sensors installed in current longwall mining systems. The big data obtained and fast communication technology have been fully utilized to improve and solve operational problems in real time. Those features are fully documented in the new edition. In pursuit of high productivity and cutting cost, life cycle management that increases equipment reliability has been implemented by OEM. Automation improvement such as tail-end automatic chain tensioner greatly extends AFC chain's service life. Other incremental improvements including dust and methane controls, entry development, panel design and face move are addressed. Additional operational issues such as extension of panel width and compatibility test are also discussed. Since the last plow longwall mine was closed in 2018, the chapter on plow longwalling has been dropped and in its place Automation of Longwall Components and System is added. Also, a new chapter Longwall Top Coal Caving Mining (LTCC) is added due to its successful application in Australia since 2005. Longwall Mining, 3rd edition will be of interest to professionals and academics in the field of mining engineering specifically, serving both as a reference work and an (under)graduate textbook, but will also interest civil, geomechanical and geological engineers and rock mechanics professionals, as well as coal operators, mining consultants, researchers, equipment manufacturers, and government regulators.

This practical and design-oriented book focuses on ground characterization and structural calculation, as part of the active structural design methodology. With a focus on rock tunnelling it offers a comprehensive rather than a topic-based perspective, deriving sound tunnel design criteria and methods from basic principles. Ground characterization includes excavations, site investigation, and in situ stress determination, culminating in geotechnical classifications. The book then deals with various construction methods and their appropriate calculations, which range from constitutive models for the stress-strain behaviour of an excavation and tunnel support elements to a full stress-strain analysis methodology. The heavily practical approach of the book draws on the authors' twenty years of tunnelling experience in Spain and South America. It will help any young or established professional who wants to develop a career in the underground field across both civil engineering and geology. As it incorporates the very fundamentals of tunneling design, it can be used as a support for tunneling courses or as a textbook for master's and PhD courses. Benjamin Celada was Chief Tunnel Engineer at Hunosa and Potasas de Navarra S.A. before founding Geocontrol S.A. He has also worked for twenty years as Professor of Underground Works at the Polytechnic Mining University in Madrid, Spain. Z. T. Bieniawski directed the Rock Mechanics Department of the Council for Scientific and Industrial Research in Pretoria, then taught at the Pennsylvania State University for twenty years.

The stability of underground and surface geotechnical structures during and after excavation is of great concern as any kind of instability may result in damage to the environment as well as time-consuming high cost repair work. The forms of instability, their mechanisms and the conditions associated with them must be understood so that correct stabilisation of the structure through rock reinforcement and/or rock support can be undertaken. Rock Reinforcement and Rock Support elucidates the reinforcement functions of rock bolts/rock anchors and support systems consisting of shotcrete, steel ribs and concrete liners and evaluates their reinforcement and supporting effects both qualitatively and quantitatively. It draws on the research activities and practices carried out by the author for more than three decades and has culminated in a most extensive up-to-date and a complete treatise on rock reinforcement and rock support.

As the structure and behavior of molecules and crystals depend on their different symmetries, group theory becomes an essential tool in many important areas of chemistry. It is a quite powerful theoretical tool to predict many basic as well as some characteristic properties of molecules. Whereas quantum mechanics provide solutions of some chemical problems on the basis of complicated mathematics, group theory puts forward these solutions in a very simplified and fascinating manner. Group theory has been successfully applied to many chemical problems. Students and teachers of chemical sciences have an invisible fear from this subject due to the difficulty with the mathematical jugglery. An active sixth dimension is required to understand the concept as well as to apply it to solve the problems of chemistry. This book avoids mathematical complications and presents group theory so that it is accessible to students as well as faculty and researchers. Chemical Applications of Symmetry and Group Theory discusses different applications to chemical problems with suitable examples. The book develops the concept of symmetry and group theory, representation of group, its applications to I.R. and Raman spectroscopy, U.V spectroscopy, bonding theories like molecular orbital theory, ligand field theory, hybridization, and more. Figures are included so that reader can visualize the symmetry, symmetry elements, and operations.

The significant challenges associated with managing waste continue to attract international scholarly attention. This international Handbook scrutinizes both developed and developing economies. It comprises original contributions from many of the most prominent scholars researching this topic. Consisting primarily of empirical research efforts - although theoretical underpinnings are also explored thoroughly - the Handbook serves to further the understanding of the behaviors of waste generators and waste processors and the array of policies influencing these behaviors.The Handbook reveals how, broadly speaking, research in the area of waste management appears to be motivated by two sources of intellectual curiosity. First is the attempt to directly or indirectly inform our understanding of the development of solid waste policy. Economic incentives, including advanced disposal fees, recycling subsidies, unit-based pricing programs, and landfill taxes, appear commonly across developed countries, and understanding how effective these policies are at diverting waste is examined carefully in the Handbook. Second, other economists are motivated to study solid waste management decisions as an avenue to understanding how incentives and norms affect individual behavior. The blossoming area of behavioral economics is especially appropriate for application to solid waste management decisions, and the Handbook contains new research contributions that add to this expanding literature. Readership will be broad including academic economists researching waste issues and researchers specializing in waste management and more widely in environmental policy, behavioral economics, and public economics. International policymakers engaged in waste management decisions will find the work enlightening. Contributors: A. Abbott, G. Abrate, A. Bucciol, S. Das, E. Dijkgraaf, Fabrizio Erbetta, I.
