Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

The twentieth century saw a proliferation of media discourses on colonialism and, later, decolonisation. Newspapers, periodicals, films, radio and TV broadcasts contributed to the construction of the image of the African “Other” across the colonial world. In recent years, a growing body of literature has explored the role of these media in many colonial societies. As regards the Italian context, however, although several works have been published about the links between colonial culture and national identity, none have addressed the specific role of the media and their impact on collective memory (or lack thereof). This book fills that gap, providing a review of images and themes that have surfaced and resurfaced over time. The volume is divided into two sections, each organised around an underlying theme: while the first deals with visual memory and images from the cinema, radio, television and new media, the second addresses the role of the printed press, graphic novels and comics, photography and trading cards.

These chapters are structured in logical sections to facilitate consultation and include major topics ranging from congenital disorders to gastrointestinal problems of the newborn, infectious diseases of the gastrointestinal tract, and approach to nutritional problems in the various pediatric ages. The second part of the book, Hepatology, is articulated in a series of chapters which present a comprehensive review of congenital and acquired disorders of the biliary tract and liver. This section also includes a critical analysis of available diagnostic and therapeutic procedures and future perspectives. Written by experts in the field, Textbook of Pediatric Gastroenterology, Hepatology and Nutrition: A Comprehensive Guide to Practice constitutes a much needed, innovative resource combining updated, reliable and comprehensive information with agile consultation for a streamlined approach to the care of children with such disorders.

A pioneering work in oral history, this book tells the story of the rise and fall of the industrial revolution and the apogee and crisis of the labor movement through an oral history of Terni, a steel town in Central Italy and the seat of the first large industrial enterprise in Italy. This story is told through a combination of stories, songs, myths and memories from over 200 voices of five generations, woven with a wealth of archival material.
