Handbook of Bioremediation: Physiological, Molecular and Biotechnological Interventions discusses the mechanisms of responding to inorganic and organic pollutants in the environment using different approaches of phytoremediation and bioremediation. Part One focuses specifically on inorganic pollutants and the use of techniques such as metallothionein-assisted remediation, phytoextraction and genetic manipulation. Part Two covers organic pollutants and consider topics such as plant enzymes, antioxidant defense systems and the remediation mechanisms of different plant species. This comprehensive volume is a must-read for researchers interested in plant science, agriculture, soil science and environmental science. The techniques covered in this book will ensure scientists have the knowledge to practice effective bioremediation techniques themselves.

This volume focuses on recent experiences of return migration to Mexico and Central America from the United States. For most of the twentieth century, return migration to the US was a normal part of the migration process from Mexico and Central America, typically resulting in the eventual permanent settlement of migrants in the US. In recent years, however, such migration has become involuntary, as a growing proportion of return migration is taking place through formal orders of deportation. This book discusses return migration to Mexico, Guatemala, El Salvador and Honduras, addressing different reasons for return, whether voluntary or involuntary, and highlighting the unique challenges faced by returnees to each region. Particular emphasis is placed on the lack of government and institutional policies in place for returning migrants who wish to attain work, training, or shelter in their home countries. Finally, the authors take a look at the phenomenon of migrants who can never return because they have disappeared during the migration process. Through its multinational focus, diverse thematic outlook, and use of ethnographic and survey methods, this volume provides an original contribution to the topic of return migration and broadens the scope of the literature currently available. As such, this book will be important to scholars and students interested in immigration policy and Latin America as well as policy makers and activists.

How ordinary Americans, frustrated by the legal and political wrangling over the Second Amendment, can fight for reforms that will both respect gun owners’ rights and reduce gun violence. Efforts to reduce gun violence in the United States face formidable political and constitutional barriers. Legislation that would ban or broadly restrict firearms runs afoul of the Supreme Court’s current interpretation of the Second Amendment. And gun rights advocates have joined a politically savvy firearms industry in a powerful coalition that stymies reform. Ian Ayres and Fredrick Vars suggest a new way forward. We can decrease the number of gun deaths, they argue, by empowering individual citizens to choose common-sense gun reforms for themselves. Rather than ask politicians to impose one-size-fits-all rules, we can harness a libertarian approach—one that respects and expands individual freedom and personal choice—to combat the scourge of gun violence. Ayres and Vars identify ten policies that can be immediately adopted at the state level to reduce the number of gun-related deaths without affecting the rights of gun owners. For example, Donna’s Law, a voluntary program whereby individuals can choose to restrict their ability to purchase or possess firearms, can significantly decrease suicide rates. Amending red flag statutes, which allow judges to restrict access to guns when an individual has shown evidence of dangerousness, can give police flexible and effective tools to keep people safe. Encouraging the use of unlawful possession petitions can help communities remove guns from more than a million Americans who are legally disqualified from owning them. By embracing these and other new forms of decentralized gun control, the United States can move past partisan gridlock and save lives now.

This book focuses on the migration of undocumented minors arriving recently to the United States and the European Union, flows that are often labeled ‘undocumented’, ‘illegal’, or ‘irregular’ and due to their sudden increase, they have been described in the media, policy circles, and scholarly work as a ‘surge’ or a ‘crisis’. Leading scholars examine the intricacies of the contexts that these minors encounter in the localities where they arrive, including the legal and ethical frameworks for protecting unaccompanied minors, governmental decisions about the ‘best interests’ of the children, these minors’ expressions of their own best interests or agency as they navigate immigration and social service systems, conditions in detention centers, and the health and social service needs in receiving communities. Though definitions and techniques for counting unaccompanied migrant minors differ between the U.S. and the EU, this book underscores the immigrant minors’ common vulnerabilities and strategies they adopt to protect themselves and improve their circumstances. At the same time, contributors to the volume highlight common challenges that both European and U.S. governments face as they develop policy strategies and legal mechanisms to attempt to balance the best interests of these children with national interests of the countries in which they settle. The chapters in this book were originally published as a special issue of the Journal of Ethnic and Migration Studies.

This volume will act as a guide through the various aspects of quantum mechanics. It not only covers the basics but also addresses new themes developed in the field of quantum mechanics in recent years. These include quantum mechanics in relation to electronics, quantum dots, spintronics, cryptography, and other more theoretical aspects, such as the path integral formulation and supersymmetric quantum mechanics. The volume presents a number of mathematical tools and physical consequences derived from quantum mechanics. The starting point of the volume is a very brief review of the phenomenology associated with the origins of quantum theory, as the branch of science was understood in the beginning of the 20th century, leading to an interpretation of the results at that time. Key features: * Provides understanding and demystification of the quantum theory * Presents applications to information theory and encryption * Introduces applications to medicine, in both treatment and diagnosis * Covers applications to modern communications systems * Looks at the philosophical implications of quantum mechanics, its reality, and its perception * Describes the application to the basics of solid state devices

As one of the fastest growing sectors of the economy since the 1950's, tourism has proved to be a complicated phenomenon, unlike any other economic producer. Over the last few decades, tourism has exerted increasing pressure on the land and negative social, environmental and economic impacts have surfaced as major issues. Positive guidelines for better planning are in demand by developers and designers who need new understandings of the breadth of tourism's complexity for their own success.

Tourism Planning has long been considered the seminal work on tourism development. It provides a comprehensive, integrated overview of all aspects of tourism and the planning functions that accompany it, emphasizing concepts and principles for better planning. The revised and updated fourth edition contains enhanced discussions of the role of communities immediately surrounding the sites using newer tourism cases as examples. Issues that have increased in importance in recent years are also discussed in depth including transportation glut, resource erosion and sprawl and sustainable development.

Galileo and Kepler dreamed of the possibility of space exploration, although its reality was later underappreciated and even challenged by social, ideological, and scientific critics as a diversion from our problems on Earth. The Dimming of Starlight tells the fascinating stories of how space exploration places us in unusual situations that force us to come up with new ideas about nature. This strong connection between scientific exploration and scientific change makes us aware of a new panorama of problems, dangers, and opportunities that leads to new solutions and technologies that would have been unimaginable under old perspectives. Thus, the exploration of Venus led to the discovery of the destruction of Earth's Ozone layer. This discovery will save hundreds of millions of lives in the coming centuries. As we explore space, we learn to protect our planet from catastrophe, and all the while we change drastically our ideas about the nature of the universe. With its account of serendipity and splendor, the book invites readers on an exciting journey in which, step by step, we are shown the crucial importance of space exploration for humanity.
