Drinking Water Minerals and Mineral Balance: Importance, Health Significance, Safety Precautions
by Ingegerd Rosborg Frantisek KozisekFollowing the successful first edition of this book on drinking water quality and health, this new edition puts more focus on the importance of minerals in drinking water. It includes new scientific material and presents additional studies on the negative health effects of reverse osmosis water. The various safety organizations working on drinking water all warn about unhealthy constituents, as well as elements that can cause corrosion or scaling on pipes and installations. However, drinking water may also provide a substantial portion of the daily mineral intake, especially for the elderly and children, or those at risk of deficiencies due to unhealthy eating habits or starvation. Thus, a holistic approach to drinking water is presented in this book and the scope is extended from standards for undesirable substances to the basic mineral composition of water, examining 22 nutrient elements and ions and 21 toxic substances. The function of the nutrients in the body, symptoms of deficiency and overload, and advantages of the minerals from drinking water are presented, as well as symptoms of toxic elements from drinking water. The authors also suggest healthy ranges of minerals and mineral ratios for drinking water. The book offers a valuable resource for the health evaluation of drinking waters, for private well owners, public water producers and safety organizations alike.
Drinking Water Security in Rural India: Dynamics, Influencing Factors, and Improvement Strategy (Water Resources Development and Management)
by Nitin Bassi M. Dinesh Kumar Saurabh KumarThis book highlights the multi-pronged strategy for achieving sustainable rural domestic water supply in India. It deepens the understanding of groundwater (predominant source of water supply) behaviour in response to natural processes in different geological settings, analyses the factors influencing the performance of water supply schemes; identifies the conditions under which groundwater-based drinking water sources become sustainable, suggests measures for improving the sustainability of drinking water wells in hard rock regions (covering 2/3rd of India’s geographical area), presents a decision-making framework for planning rural water supply schemes in the country for ensuring long-term sustainability, and suggests physical strategies and policy measures for achieving them.The analyses for development and validation of various models that explain groundwater system behaviour and performance of rural water supply schemes are undertaken for different geological settings in Maharashtra, as the state represents a microcosm of the various hydrological, topographical, and geohydrological conditions encountered in the country. The final analysis for proposing nation-wide strategies considers the various hydrological, geological, geohydrological, and topographical and climatic settings and groundwater contamination and pollution in the country.
Drinking Water Treatment
by Ravi Jain Chittaranjan RaySustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses. Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to "democratize" membrane filtration have been presented. Riverbank filtration is a "natural" filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.

Drinking Water in Sicily: Hydrogeological and Hydrogeochemical Aspects
by Esterina Gagliano Candela Giovannella Pecoraino Sabina Morici Leonardo La PicaThis book consists of the hydrogeochemical study of the springs of the Sicilian territory used for drinking water purposes. One of the most important issues in the environmental field is the protection of water resources and in particular the safeguarding of water intended for drinking water use. Water resources need a careful prevention of pollution starting from multidisciplinary studies (geology, hydrogeology, geochemistry, geophysics) to understand the territory in order to highlight vulnerable areas and then plan, where necessary, monitoring activities for the control and protection of the resource. The reference is the Piano Regolatore degli Acquedotti (PRGA) of Sicily, Italy (updated in November 2010), which lists all the springs, subdivided by province (a total of 1014), currently used to supply water to Sicilian aqueducts. With regard to the geochemical part, the studies carried out by the INGV, Sezione di Palermo, for the Water Protection Plan for Sicily (2004-2005) were used as basic data. The study of the chemical characteristics of groundwater is of fundamental importance from a hydrogeological point of view as it allows the origin of the water and its evolution to be reconstructed. Springs as a groundwater resource are of considerable importance in relation to the availability of water resources due to the general decrease in precipitation. In the first part of the book all the existing data (flow rates, geochemical parameters, water quality, etc.) are collected and subsequently transferred to GIS software, after appropriate evaluations on the validity of the acquired data. Considering that the subject is quite delicate and involves various aspects (compliance with regulations, vulnerability of groundwater, anthropogenic pollution, etc.), carrying out a purely scientific study allows groundwater to be placed in a broader context than that of legislation aimed exclusively at compliance with the regulations in force.

Drivers of Climate Change in Urban India: Social Values, Lifestyles, and Consumer Dynamics in an Emerging Megacity (Springer Climate)
by Lutz Meyer-OhlendorfThis study transcends the homogenizing (inter-)national level of argumentation (‘rich’ versus ‘poor’ countries), and instead looks at a sub-national level in two respects: (1) geographically it focuses on the rapidly growing megacity of Hyderabad; (2) in socio-economic terms the urban population is disaggregated by taking a lifestyle typology approach. For the first time, the lifestyle concept – traditionally being used in affluent consumer societies – is applied to a dynamically transforming and socially heterogeneous urban society. Methodically, the author includes India-specific value orientations as well as social practices as markers of social structural differentiation. The study identifies differentials of lifestyle-induced GHG emissions (carbon footprints) and underlines the ambiguity of a purely income based differentiation with regard to the levels of contribution to the climate problem.
Drivers of Environmental Change in Uplands (Routledge Studies in Ecological Economics)
by Jon Stewart Aletta Bonn Tim Allott Klaus HubacekThe uplands are a crucial source of ecosystem services, such as water provision, carbon retention, maintenance of biodiversity, provision of recreation value and cultural heritage. This puts them in the focus of both environmental and social scientists as well as practitioners and land managers.. This volume brings together a wealth of knowledge of the British uplands from diverse but interrelated fields of study, clearly demonstrating their importance in 21st Century Britain, and indicating how we may through interdisciplinary approaches meet the challenges provided by past and future drivers of environmental change.The upland environments are subject to change. They face imminent threats as well as opportunities from pressures such as climate change, changes in land management and related changes in fire risk, increases in erosion and water colour, degradation of habitats, altered wildlife and recreational value, as well as significant changes in the economy of these marginal areas. This book presents up-to-date scientific background information, addresses policy related issues and lays out pressing land management questions. A number of world-class experts provide a review of cutting-edge naturaland social science and an assessment of past, current and potential future management strategies, policies and other drivers of change. After appraisal of key concepts and principles, chapters provide specific examples and applications by focussing on UK upland areas and specifically the Peak District National Park as a key example for other highly valuable upland regions.
Drivers of Landscape Change in the Northwest Boreal Region
by Valerie BarberThe northwest boreal region (NWB) of North America is a land of extremes. Extending more than 1.3 million square kilometers (330 million acres), it encompasses the entire spectrum between inundated wetlands below sea level to the tallest peak in North America. Permafrost gradients span from nearly continuous to absent. Boreal ecosystems are inherently dynamic and continually change over decades to millennia. The braided rivers that shape the valleys and wetlands continually change course, creating and removing vast wetlands and peatlands. Glacial melt, erosion, fires, permafrost dynamics, and wind-blown loess are among the shaping forces of the landscape. As a result, species interactions and ecosystem processes are shifting across time. The NWB is a data-poor region, and the intention of the NWB Landscape Conservation Cooperative is to determine what data are not available and what data are available. For instance, historical baseline data describing the economic and social relationships in association with the ecological condition of the NWB landscape are often lacking. Likewise, the size and remoteness of this region make it challenging to measure basic biological information, such as species population sizes or trends. The paucity of weather and climate monitoring stations also compound the ability to model future climate trends and impacts, which is part of the nature of working in the north. The purpose of this volume is to create a resource for regional land and resource managers and researchers by synthesizing the latest research on the historical and current status of landscape-scale drivers (including anthropogenic activities) and ecosystem processes, future projected changes of each, and the effects of changes on important resources. Generally, each chapter is coauthored by researchers and land and natural resource managers from the United States and Canada.
Driving Force: The Natural Magic of Magnets
by James D. LivingstonDriving Force unfolds the long and colorful history of magnets: how they guided (or misguided) Columbus; mesmerized eighteenth-century Paris but failed to fool Benjamin Franklin; lifted AC power over its rival, DC, despite all the animals, one human among them, executed along the way; led Einstein to the theory of relativity; helped defeat Hitler’s U-boats; inspired writers from Plato to Dave Barry. In a way that will delight and instruct even the nonmathematical among us, James Livingston shows us how scientists today are creating magnets and superconductors that can levitate high-speed trains, produce images of our internal organs, steer high-energy particles in giant accelerators, and—last but not least—heat our morning coffee. From the “new” science of materials to everyday technology, Driving Force makes the workings of magnets a matter of practical wonder. The book will inform and entertain technical and nontechnical readers alike and will give them a clearer sense of the force behind so much of the working world.
Driving Justice, Equity, Diversity, and Inclusion
by Kristina KohlNavigating the volatility, uncertainty, complexity, and ambiguity (VUCA) characterizing the business world in the 21st century requires a new paradigm focused on an integrated bottom line – planet, people, and profit (PPP). Global trends include resource scarcity and growing inequities in income, wealth, education, and healthcare. Stakeholders are demanding that organizations address systemic barriers to promote justice and equity within organizations and across broader social systems. Transformational change requires leadership to analyze internal and external systems through a social and environmental justice lens. Despite a growing focus on justice, equity, diversity, and inclusion, the imbalance of power remains within our institutions, organizations, and social systems. To move the needle, leaders can turn to Driving Justice, Equity, Diversity, and Inclusion, which explains developing a North Star vision and creating a strategy to redesign organizational process and systems, as well as leveraging tools for data-driven decision-making. It presents a framework to build an inclusive organization as well as a model to engage and support senior and middle management beginning the process of capacity building and systemic change. By layering in AI and other technologies to support data-driven decision-making, the book guides leaders in navigating their organization’s journey along the maturity continuum to achieve their North Star vision of becoming a just and equitable organization. The book also helps managers to Assess ecosystems and organizational systems that justice, equity, diversity, and inclusion impact Take a deeper dive into transformational and operational components to gain insights on the deep systemic realignment of the North Star vision Identify and engage with diverse stakeholders to gain perspective and understand issues crucial for transformative change Leverage people-centered design to create a process promoting diversity of voices and to better align outcomes with shared organizational vision Use data to drive decision-making and reduce bias by removing intuition from the decision-making process Leverage the book's frameworks to drive collaborative systemic change Adapt insights highlighted in multiple interviews with DEI practitioners Benefit from lessons learned and best practices featured in the book's case studies This book features a primer, which is a quick reference guide to key terms, concepts, and definitions. It helps to define justice, equity, diversity, inclusion, and other key terms, such as unconscious bias, stereotypes, and microaggressions. It also features a toolkit, which includes checklists to help managers lead organizations to realize their own North Star vision.

Driving the Future: Combating Climate Change with Cleaner, Smarter Cars
by Fred Krupp Margo T OgeNow in paperback, with a new foreword by Fred Krupp, an expert's illuminating preview of the cleaner, lighter, smarter cars of the future.In Driving the Future, Margo T. Oge portrays a future where clean, intelligent vehicles with lighter frames and alternative power trains will produce zero emissions and run at 100+ mpg. With electronic architectures more like those of airplanes, cars will be smarter and safer, will park themselves, and will network with other vehicles on the road to drive themselves. As the director of the EPA’s Office of Transportation and Air Quality, Oge was the chief architect behind the Obama administration’s landmark 2012 deal with automakers in the US market to double the fuel efficiency of their fleets and to cut greenhouse gas emissions in half by 2025. This was America’s first formal climate action using regulation to reduce emissions through innovation in car design.Offering an insider account of the partnership between federal agencies, California, environmental groups, and car manufacturers that led to the historic deal, Margo discusses the science of climate change, the politics of addressing it, and the lessons learned for policy makers. She also takes the reader through the convergence of macro trends that will drive this innovation over the next forty years and be every bit as transformative as those wrought by Karl Benz and Henry Ford. Driving the Future is for anyone who wants to know what car they’ll be driving in ten, twenty, or thirty years-and for everyone concerned about air quality and climate change now.

Droplet Interactions and Spray Processes (Fluid Mechanics and Its Applications #121)
by Bernhard Weigand Grazia Lamanna Simona Tonini Gianpietro Elvio CossaliThis book provides a selection of contributions to the DIPSI workshop 2019 (Droplet Impact Phenomena & Spray Investigations) as well as recent progress of the Int. Research Training Group “DROPIT”.The DIPSI workshop, which is now at its thirteenth edition, represents an important opportunity to share recent knowledge on droplets and sprays in a variety of research fields and industrial applications. The research training group “DROPIT” is focused on droplet interaction technologies where microscopic effects influence strongly macroscopic behavior. This requires the inclusion of interface kinetics and/or a detailed analysis of surface microstructures. Normally, complicated technical processes cover the underlying basic mechanisms, and therefore, progress in the overall process modelling can hardly be gained. Therefore, DROPIT focuses on the underlying basic processes. This is done by investigating different spatial and/or temporal scales of the problems and by linking them through a multi-scale approach. In addition, multi-physics are required to understand e.g. problems for droplet-wall interactions, where porous structures are involved.
