Book Description
The rapid revolution in modern industry has led to a significant increase in waste at the end of the product lifecycle. It is essential to close the loop, secure resources, and join up the circular economy. This book provides a detailed review of extraction techniques for urban mining of precious metals including gold, silver, and the platinum group. The merits and demerits of various extraction methods are highlighted, with possible suggestions for improvements. The feasibility of hybrid extraction techniques, as well as the sustainability and environmental impact of every process, is explored. Offers a comprehensive review of different techniques used in recycling technology for urban mining of precious metals Describes the concept of urban mining and its correlation with circular economy Discusses feasibility of precious metal extraction and urban mines scope and their potential Explains the subject in-context of sustainability while describing chemistry fundamentals and industrial practices Provides technical flow sheets for urban mining of precious metals with diversity of lixiviant This book is aimed at graduate students and researchers in extractive metallurgy, hydrometallurgy, chemical engineering, chemistry, and environmental engineering.

Book Description
Deborah Levenson-Estrada provides the first comprehensive analysis of how urban labor unions took shape in Guatemala under conditions of state terrorism. In Trade Unionists against Terror, she explores how workers made sense of their struggle for rights in the face of death squads and other forms of violent opposition from the state. Levenson-Estrada focuses especially on the case of 400 workers at the Coca-Cola bottling plant in Guatemala City, who, in order to protect their union, successfully occupied the factory for over a year beginning in 1984 while the country was under a state of siege. According to Levenson-Estrada, religion provided the language of resistance, and workers who were engaged in what seemed to be a dead-end battle constructed an identity for themselves as powerful agents of change. Based on oral histories as well as documentary sources, Trade Unionists against Terror also illuminates complex relationships between urban popular culture, gender, family, and workplace activism in Guatemala.

Book Description
This book presents technical information and materials concerning the engineering of decentralized infrastructure to achieve effective wastewater treatment while also minimizing resource consumption and providing a source of reclaimed water, nutrients and organic matter. The approaches, technologies and systems described are targeted for green building and sustainable infrastructure across the United States and similar industrialized nations, but they are also applicable to water and sanitation projects in developing regions around the world. Today, decentralized infrastructure can be used to sustainably serve houses, buildings and developments with water use and wastewater flows of 100 to 100,000 gal/d or more. The book provides in-depth engineering coverage of the subject in a narrative and slide format specifically designed for classroom lectures or facilitated self-study. Key topics are covered including: engineering to satisfy project goals and requirements including sustainability, contemporary water use and wastewater generation and methods to achieve water use efficiency and source separation, alternative methods of wastewater collection and conveyance, and treatment and reuse operations including tank-based (e.g., septic tanks, aerobic treatment units, porous media biofilters, membrane bioreactors), wetland-based (e.g., free water surface and vegetated subsurface bed wetlands), and land-based unit operations (e.g., subsurface soil infiltration, shallow drip dispersal). Approaches and technologies are also presented that can achieve nutrient reduction and resource recovery in some cases or pathogen destruction to enable a particular discharge or reuse plan. The book also describes requirements and methods for effective management of the process solids, sludges and residuals that can be generated by various approaches, technologies, and systems. The book contains over 300 figures and illustrations of technologies and systems and over 150 tables of design and performance data. There are also more than 200 questions and problems relevant to the topics covered including example problems that have solutions presented to illustrate engineering concepts and calculations.

Book Description
From Katy Perry training alongside US Marines in a music video, to the global box-office mastery of the US military-supported Transformers franchise, to the explosion of war games such as Call of Duty, it’s clear that the US security state is a dominant force in media culture. But is the ubiquity of cultural products that glorify the security state a new phenomenon? Or have Uncle Sam and Hollywood been friends for a long time? Hearts and Mines examines the rise and reach of the US Empire’s culture industry – a nexus between the US’s security state and media firms and the source of cultural products that promote American strategic interests around the world. Building on and extending Herbert I. Schiller’s classic study of US Empire and communications, Tanner Mirrlees interrogates the symbiotic geopolitical and economic relationships between the US state and media firms that drive the production of imperial culture.

Book Description
1999 North American Society for Sports History Book of the Year Douglas Booth looks at the role of sport in the fostering of a new national identity in South Africa. He analyzes the effect of the 30-year sport boycott but concludes that sport will never unite South Africans except in the most fleeting and superficial manner.
