Natural Polymers, Biopolymers, Biomaterials, and Their Composites, Blends, and IPNs focuses on the recent advances in natural polymers, biopolymers, biomaterials, and their composites, blends, and IPNs. Biobased polymer blends and composites occupy a unique position in the dynamic world of new biomaterials. The growing need for lubricious coatings and surfaces in medical devices-an outcome of the move from invasive to noninvasive medicines/procedures-is playing a major role in the advancement of biomaterials technology. Natural polymers have attained their cutting-edge technology through various platforms, yet there is a lot of novel information about them that is discussed in the book. This important work covers topics such as chitosan composites for biomedical applications and wastewater treatment, coal biotechnology, biomedical and related applications of second generation polyamidoamines, silk fibers, PEG hydrogels, bamboo fiber reinforced PE composites, jute/polyester composites, magnetic biofoams, and many other interesting aspects of importance to polymer research today.

Livelihoods in rural Africa are changing in response to disappearing job prospects, falling agricultural output and collapsing infrastructure. This book explains why the responses to these challenges are so different in different parts of Africa. Making a Living uses case studies from commercial farming regions in Kenya, Tanzania and Zimbabwe and from much poorer areas within eastern and southern Africa.to give a broad comparative study of rural livelihoods. These case studies reveal how household relations, poverty and gender all play a part in the changing political economy of rural Africa.

This handbook explores how democracies around the world seek to balance democratic values with the requirement to protect their citizens from the threat of politically motivated violence. Over the past few decades, the majority of the world's democracies have had to confront serious security threats, and in many instances these challenges have not come from rival states but from violent groups. This volume offers readers an overview of how some democracies have responded to such threats. It examines the extent to which authorities have felt compelled to modify laws to evade what would ordinarily be regarded as protected rights, such as personal privacy, freedom of movement and freedom of speech. Grounded in historical analysis, each of the sections addresses past and emerging security threats; legal and legislative responses to them; successful and unsuccessful efforts to reconcile democracy and security; and a range of theoretical questions. The case studies provided vary in terms of the durability of their democratic systems, level of economic development and the severity of the threats with which they have been confronted. The volume is divided into three thematic parts: Strong democracies: United States, Great Britain, France, Germany, Italy, Spain, Australia, New Zealand and Israel Challenged democracies: India, South Africa, Brazil, Argentina and Romania Fragile democracies: the Philippines and Nigeria. This book will be of much interest to students of democracy, security studies, political philosophy, Asian politics, Middle Eastern politics, African politics, West European politics and IR in general.
