This book is devoted to sewage sludge, its sustainable management, and its use and implications on soil fertility and crop production. The book traces the main chemical and biological properties of sewage sludge, and covers topics such as sewage sludge biostabilization and detoxification, biological and thermochemical treatment technologies, emerging nutrient recovery technologies, the role of microorganisms in sewage sludge management, and the sustainable use of sewage sludge as fertilizer in agriculture. The book offers a valuable asset for researchers, scholars and policymakers alike.
Interest in solid and hazardous waste management is relatively recent, i.e., in the last three decades, and is driven by regulations in most countries. It began with industrial hazardous waste followed by municipal solid waste, and subsequently by many other categories of waste. This book presents numerous examples and case studies of innovative tools, treatment methods and applications in this growing area of research and development. It describes in detail laboratory methods of measuring the biodegradation of specific organic fractions, like floral waste, and also discusses the treatment of yard and food waste by anaerobic digestion and landfill leachate using constructed wetlands. Case st...
This book reviews the prevalence and variants of consumer subsidies found in the developing world and the effectiveness of these subsidies for the poor. It places consumer subsidies in a broader social protection framework and compares them with poverty-focused programmes in other sectors using a common metric. It concludes that the most common subsidy instruments perform poorly in comparison with most other transfer mechanisms. Alternative consumption and connection subsidy mechanisms show more promise, especially when combined with complementary non-price approaches to making utility services accessible and affordable to poor households. The many factors contributing to those outcomes are dissected, identifying those that can be controlled and used to improve performance.

This book provides a comprehensive typological account of voice syncretism, focusing on resemblance in formal verbal marking between two or more of the following seven voices: passives, antipassives, reflexives, reciprocals, anticausatives, causatives, and applicatives. It covers voice syncretism from both synchronic and diachronic perspectives, and has been structured in a manner that facilitates convenient access to information about specific patterns of voice syncretism, their distribution and development. The book is based on a survey of voice syncretism in 222 geographically and genealogically diverse languages, but also thoroughly revisits previous research on the phenomenon. Voice syn...
Dive into Combine! Writing asynchronous code can be challenging, with a variety of possible interfaces to represent, perform, and consume asynchronous work - delegates, notification center, KVO, closures, etc. Juggling all of these different mechanisms can be somewhat overwhelming. Does it have to be this hard? Not anymore! In this book, you'll learn about Combine - Apple's framework to work with asynchronous events in a unified and reactive way that ensures your app is always up to date based on the latest state of its data. Who This Book Is For This book is for intermediate iOS developers who already know the basics of iOS and Swift development but are interested in learning declarative/re...
