Water distribution systems are made up of pipe, valves and pumps through which treated water is moved from the treament plant to homes, offices, industries, and other consumers. The types of materials and equipment used by each water system are usually governed by local conditions, past practices, and economics. Consequently, drinking water professionals must be knowledgeable about common types of equipment and operating methods that are available. Completely revised and updated, Water transmission and distribution includes information on the following: distribution system design and operation and maintenance ; piping materials ; valves, pumps, and water meters ; water main installation ; backfilling, main testing, and installation safety ; fire hyfrants ; water storage ; water services ; cross-connection control ; motors and engines ; instrumentation and control ; information management and public relations.--Cover page [4].

TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.

This volume provides a complete update of all the materials in prior volumes on the subject (including current directories to testing labs and other support establishments worldwide), while adding substantial new material on the following topics: · The history of CROs, including snapshots of CROs and a genealogy chart making clear where they came from and where they went. · Study directors and principal investigators. · The nuts and bolts of study performance. · Electronic reporting requirements – SEND and eCTD (required for NDA, BLA, ANDA, and IND submissions). · Consultants and their roles. · An expanded examination of common problems and their solutions. This book boasts complete directories to the global universe of operating labs – where they are, how to contact them, and what they do (including special capabilities). Additionally, checklists for qualifying labs and manufacturing facilities – and for auditing studies and projects at such facilities – are included. It is directed at those in industry (specifically directed at those working for companies using CRO services) but will also be of interest to scientists or administrators working in research organizations themselves. In this case, the contents of this new work are essential to the target reader because the work, regulations, and actors (CROs) have evolved and changed at a rapid pace in the 10 years since the earlier volume that the author published. Likewise, the companies using these services have come to all be almost completely dependent on outsourcing. The earlier texts remain the only source of their kind (paper or electronic) on the field and the only noncommercial guide to the global industry and this volume provides a complete update.

Expanding Underground - Knowledge and Passion to Make a Positive Impact on the World contains the contributions presented at the ITA-AITES World Tunnel Congress 2023 (Athens, Greece, 12 – 18 May, 2023). Tunnels and underground space are a predominant engineering practice that can provide sustainable, cost-efficient and environmentally friendly solutions to the ever-growing needs of modern societies. This underground expansion in more diverse and challenging infrastructure types or to novel underground uses can foster the changes needed. At the same time, the tunneling and underground space community needs to be better prepared and equipped with knowledge, tools and experience, to deal with the prevailing conditions, to successfully challenge and overcome adversities on this path. The papers in this book aim at contributing to the analysis of challenging conditions, the presentation and dissemination good practices, the introduction of new concepts, new tools and innovative elements that can help engineers and all stakeholders to reach their end goals. Expanding Underground - Knowledge and Passion to Make a Positive Impact on the World covers a wide range of aspects and topics related to the whole chain of the construction and operation of underground structures: Knowledge and Passion to Expand Underground for Sustainability and Resilience Geological, Geotechnical Site Investigation and Ground Characterization Planning and Designing of Tunnels and Underground Structures Mechanised Tunnelling and Microtunnelling Conventional Tunnelling, Drill-and-Blast Applications Tunnelling in Challenging Conditions - Case Histories and Lessons Learned Innovation, Robotics and Automation BIM, Big Data and Machine Learning Applications in Tunnelling Safety, Risk and Operation of Underground Infrastructure, and Contractual Practices, Insurance and Project Management The book is a must-have reference for all professionals and stakeholders involved in tunneling and underground space development projects.
