Book Description
Minerals are part of virtually every product we use. Common examples include copper used in electrical wiring and titanium used to make airplane frames and paint pigments. The Information Age has ushered in a number of new mineral uses in a number of products including cell phones (e.g., tantalum) and liquid crystal displays (e.g., indium). For some minerals, such as the platinum group metals used to make cataytic converters in cars, there is no substitute. If the supply of any given mineral were to become restricted, consumers and sectors of the U.S. economy could be significantly affected. Risks to minerals supplies can include a sudden increase in demand or the possibility that natural ores can be exhausted or become too difficult to extract. Minerals are more vulnerable to supply restrictions if they come from a limited number of mines, mining companies, or nations. Baseline information on minerals is currently collected at the federal level, but no established methodology has existed to identify potentially critical minerals. This book develops such a methodology and suggests an enhanced federal initiative to collect and analyze the additional data needed to support this type of tool.

Book Description
Metal recycling is a complex business that is becoming increasingly difficult! Recycling started long ago, when people realized that it was more resource- and cost-efficient than just throwing away the resources and starting all over again. In this report, we discuss how to increase metal-recycling rates - and thus resource efficiency - from both quantity and quality viewpoints. The discussion is based on data about recycling input, and the technological infrastructure and worldwide economic realities of recycling. Decision-makers set increasingly ambitious targets for recycling, but far too much valuable metal today is lost because of the imperfect collection of end-of-life (EoL) products, improper practices, or structural deficiencies within the recycling chain, which hinder achieving our goals of high resource efficiency and resource security, and of better recycling rates.

Book Description
This book deals with slums as a specific question and a central focus in urban planning. It radically reverses the official version of the history of world cities as narrated during decades: slums are not at the margin of the contemporary process of urbanization; they are an integral part of it. Taking slums as its central focus and regarding them as symptomatic of the ongoing transformations of the city, the book moves to the very heart of the problem in urban planning. The book presents 16 case studies that form the basis for a theory of the slum and a concrete development manual for the slum. The interdisciplinary approach to analysing slums presented in this volume enables researchers to look at social and economic dimensions as well as at the constructive and spatial aspects of slums. Both at the scientific and the pedagogical level, it allows one to recognize the efforts of the slum’s residents, key players in the past, and present development of their neighborhoods, and to challenge public and private stakeholders on priorities decided in urban planning, and their mismatches when compared to the findings of experts and the demands of users. Whether one is a planner, an architect, a developer or simply an inhabitant of an emerging city, the presence of slums in one’s environment – at the same time central and nonetheless incongruous – makes a person ask questions. Today, it is out of the question to be satisfied with the assumption of the marginality of slums, or of the incongruous nature of their existence. Slums are now fully part of the urban landscape, contributing to the identity and the urbanism of cities and their stakeholders.

This history of coiffure in modern France illuminates a host of important twentieth-century issues: the course of fashion, the travails of small business in a modern economy, the complexities of labour reform, the failure of the Popular Front, the temptations of Pétainism, all accompanied by a parade of waves, chignons, and curls.

Book Description
This edited book provides a comprehensive account of the sustainable intensification process through various forms of case studies and scientific approaches studied across the globe. It also focuses on the agroecosystem services and their subsequent management for ecological integrity. The book helps to understand the interconnection of food, nutrition, economic growth, and environmental security on the planet. It provides comprehensive information with photographic illustration and various other forms of scientific databases on sustainable intensification of agroecosystems. The book also supports decision-making, strategies, and policy formulation for effective implementation of sustainable intensification towards higher productivity along with maintenance and management of agroecosystem services. Proper sustainable intensification of agroecosystem services and their management by maintaining ecological harmony is the future prospect for sustainable development. High input agriculture gives rise to a high-energy footprint, agricultural pollution, resource depletion, loss of agro-biodiversity, and decline of human health. Through this connection, the sustainable intensification approach addresses the advanced food security, sustainability, and overall prosperity of humankind. The book is helpful for both undergraduate and postgraduate students, policymakers, the farming community, as well as the scientific community across the globe to understand the concept of sustainable intensification and its application in relevant fields for proper management of agroecosystems services.
