Increasing concern with fuel consumption leads to widespread interest in lightweight structures for transportation vehicles. Several competing technologies are available for the structural connections of these structures, namely welding, mechanical fastening / riveting, and adhesive technologies. Arranged in a single volume, this work is to presents state-of-the-art discussions of those aspects and processes presenting greater novelty whilst simultaneously keeping wide applicability potential and interest. The topics chosen have the common feature of being of currently applied in lightweight structures, and one of the characteristics of this work is bringing together relevant state-of-the-art information usually presented in separate publications specializing in a single technology. The book provides discussions and examples of concrete applications, so that it appeals to researchers and designers and engineers involved in the design and fabrication of lightweight structures.

This volume, by graduate researchers working in urban agriculture, examines concrete strategies to integrate city farming into the urban landscape. Drawing on original field work in cities across the rapidly urbanizing global south, the book examines the contribution of urban agriculture and city farming to livelihoods and food security. Case studies cover food production diversification for robust and secure food provision; the socio-economic and agronomic aspects of urban composting; urban agriculture as a viable livelihood strategy; strategies for integrating city farming into urban landscapes; and the complex social-ecological networks of urban agriculture. Other case studies look at public health aspects including the impact of pesticides, micro-biological risks, pollution and water contamination on food production and people. Ultimately the book calls on city farmers, politicians, environmentalists and regulatory bodies to work together to improve the long term sustainability of urban farming as a major, secure source of food and employment for urban populations.

As a society we are buying more sex than ever before. Adult sex shops now take their place amongst retailers in the high street and lap dancing clubs compete for an increased share of the leisure economy; hotel chains offer sexually explicit films as part of their standard service, the party selling of adult toys to women in their homes has become a mainstream activity; and at the traditional end of the sexual service economy, prostitution has experienced new growth. Along with this has come new legal measures and attempts to regulate the sexual leisure economy, and far more comprehensive plans than ever before to regulate prostitution, in particular in the form of the new Sex Offences Act. This book seeks to address the range of issues and contemporary debates on the sex industry, including the demand by customers who buy sex, the policing of women who work in the street sex industry, and the violence that pervades prostitution. It shows how these issues have been addressed in policy terms, the problems that have emerged in this, and how a social policy might be formulated to minimize harm and enhance public understanding. Overall the book aims to provide a critical perspective on prostitution policies and the legal chaos and complexities that surround this.

Infections must be thought as one of the most important, if not the most important, risk factors for cancer development in humans. Approximately 15-20% of all cases of cancer around the world are caused by viruses. The establishment of a causal relationship between the presence of specific infective agents and certain types of human cancer represents a key step in the development of novel therapeutic and preventive strategies. In this book, Professor zur Hausen (Nobel Prize in Physiology/Medicine 2008) provides a thorough and comprehensive overview on carcinogenic infective agents -- viruses, bacteria, parasites and protozoons -- as well as their corresponding transforming capacities and mechanisms. The result is an invaluable and instructive reference for all oncologists, microbiologists and molecular biologists working in the area of infections and cancer. The author was among the first scientists to reveal the cervical cancer-inducing mechanisms of human papilloma viruses and isolated HPV16 and HPV18, and, as early as 1976, published the hypothesis that wart viruses play a role in the development of this type of cancer.
