The IWA Performance Indicator System for water services is now recognized as a worldwide reference. Since it first appearance in 2000, the system has been widely quoted, adapted and used in a large number of projects both for internal performance assessment and metric benchmarking. Water professionals have benefited from a coherent and flexible system, with precise and detailed definitions that in many cases have become a standard. The system has proven to be adaptable and it has been used in very different contexts for diverse purposes. The Performance Indicators System can be used in any organization regardless of its size, nature (public, private, etc.) or degree of complexity and development. The third edition of Performance Indicators for Water Supply Services represents a further improvement of the original manual. It contains a reviewed and consolidated version of the indicators, resulting from the real needs of water companies worldwide that were expressed during the extensive field testing of the original system. The indicators now properly cover bulk distribution and the needs of developing countries, and all definitions have been thoroughly revised. The confidence grading scheme has been simplified and the procedure to assess the results- uncertainty has been significantly enhanced. In addition to the updated contents of the original edition, a large part of the manual is now devoted to the practical application of the system. Complete with simplified step-by-step implementation procedures and case studies, the manual provides guidelines on how to adapt the IWA concepts and indicators to specific contexts and objectives. This new edition of Performance Indicators for Water Supply Services is an invaluable reference source for all those concerned with managing the performance of the water supply industry, including those in the water utilities as well as regulators, policy-makers and financial agencies.
The public water supply, urban wastewater and urban waste management services are essential to the well-being of citizens, public health and economic activities. These are generally provided under natural or legal monopoly, so there is no incentive for utilities to search for greater efficiency and effectiveness and as such there is an increasing prevalence of such risks for users. For these reasons, society can significantly benefit from the existence of regulatory intervention capable of introducing greater balance in the relationship between utilities and their users. The Regulation of Water and Waste Services: An Integrated Approach (Rita-Ersar) presents a practical integrated regulatory approach to these water and waste services. This approach is called the ARIT-ERSAR model and it is capable of contributing to the promotion of access by citizens to these services that is tending towards the universal. These services are provided with suitable quality by utilities at socially acceptable prices and with an acceptable level of risk. This approach consists of a regulation model with two major areas of intervention: structural regulation of the sector and regulation of the performance of the utilities. The components of structural regulation are contributions to organisation, legislation, information and sectoral capacity building. The performance regulation of utilities consists of legal and contractual regulation, economic regulation, quality of service regulation, drinking water quality regulation and user interface regulation.

A riveting memoir and a fascinating investigation of the history, uses, and controversies behind lithium, an essential medication for millions of people struggling with bipolar disorder. It began in Los Angeles in 1993, when Jaime Lowe was just sixteen. She stopped sleeping and eating, and began to hallucinate—demonically cackling Muppets, faces lurking in windows, Michael Jackson delivering messages from the Neverland Underground. Lowe wrote manifestos and math equations in her diary, and drew infographics on her bedroom wall. Eventually, hospitalized and diagnosed as bipolar, she was prescribed a medication that came in the form of three pink pills—lithium. In Mental, Lowe shares and investigates her story of episodic madness, as well as the stability she found while on lithium. She interviews scientists, psychiatrists, and patients to examine how effective lithium really is and how its side effects can be dangerous for long-term users—including Lowe, who after twenty years on the medication suffers from severe kidney damage. Mental is eye-opening and powerful, tackling an illness and drug that has touched millions of lives and yet remains shrouded in social stigma. Now, while she adjusts to a new drug, her pursuit of a stable life continues as does her curiosity about the history and science of the mysterious element that shaped the way she sees the world and allowed her decades of sanity. Lowe travels to the Bolivian salt flats that hold more than half of the world’s lithium reserves, rural America where lithium is mined for batteries, and tolithium spas that are still touted as a tonic to cure all ills. With unflinching honesty and humor, Lowe allows a clear-eyed view into her life, and an arresting inquiry into one of mankind’s oldest medical mysteries.
This book addresses the fundamental technologies, architectures, application domains, and future research directions of the Internet of Things (IoT). It also discusses how to create your own IoT system according to applications requirements, and it presents a broader view of recent trends in the IoT domain and open research issues. This book encompasses various research areas such as wireless networking, advanced signal processing, IoT, and ubiquitous computing. Internet of Things: Theory to Practice discusses the basics and fundamentals of IoT and real-time applications, as well as the associated challenges and open research issues. The book includes several case studies about the use of IoT in day-to-day life. The authors review various advanced computing technologies—such as cloud computing, fog computing, edge computing, and Big Data analytics—that will play crucial roles in future IoT-based services. The book provides a detailed role of blockchain technology, Narrowband IoT (NB-IoT), wireless body area network (WBAN), LoRa (a longrange low power platform), and Industrial IoT (IIoT) in the 5G world. This book is intended for university/college students, as well as amateur electronic hobbyists and industry professionals who are looking to stay current in the IoT domain.
A NATIONAL BESTSELLER Sy Montgomery, New York Times best-selling author and recipient of numerous awards, edits this year’s volume of the finest science and nature writing. “Science is important because this is how we seek to discover the truth about the world. And this is what makes excellent science and nature writing essential,” observes New York Times best-selling author Sy Montgomery. “Science and nature writing are how we share the truth about the universe with the people of the world.” And collected here are truths about nearly every corner of the universe. From meditations on extinction, to the search for alien life, to the prejudice that infects our medical system, the pieces in this year’s Best American Science and Nature Writing seek to bring to the people stories of some of the most pressing issues facing our planet, as well as moments of wonder reflecting the immense beauty our natural world offers.
