During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the eff...

Preventing humanitarian atrocities is becoming as important for the United Nations as dealing with inter-state war. In this book, Ramesh Thakur examines the transformation in UN operations, analysing its changing role and structure. He asks why, when and how force may be used and argues that the growing gulf between legality and legitimacy is evidence of an eroded sense of international community. He considers the tension between the US, with its capacity to use force and project power, and the UN, as the centre of the international law enforcement system. He asserts the central importance of the rule of law and of a rules-based order focused on the UN as the foundation of a civilised system of international relations. This book will be of interest to students of the UN and international organisations in politics, law and international relations departments, as well as policymakers in the UN and other NGOs.
This textbook provides a comprehensive and state-of-the-art overview of the major issues specific to the field of pediatric gastroenterology, hepatology, and nutrition.

Pulmonary arterial hypertension (PAH) continues to be a condition associated with a high morbidity and mortality despite the advances in treatment strategies over the past 25 years. Although defined by strict hemodynamic criteria, PAH is a syndrome based on diverse etiologies and pathogenesis. PAH is characterized by excessive pulmonary vascular remodeling, pulmonary arterial obstruction and elevated pulmonary vascular resistance (PVR), which result in a marked increase in right ventricle (RV) afterload. Eventually, the RV is not able to cope with the increased load and HF develops.
This collection of original papers is a representative survey of recent theoretical and cross-linguistic work on reciprocity and reflexivity. Its most remarkable feature is its combination of formal approaches, case studies on individual languages and broad typological surveys in one volume, showing that the interaction of formal approaches to grammar and typology may lead to new insights and results for both fields. Among the major issues addressed in this volume are the following: How can our current knowledge about the space and limits of variation in the relevant domain be captured in a structural typology of reciprocity? What light can such a typology shed on the facts of particular lan...
Akira Toriyama's groundbreaking, iconic, best-selling series now in an omnibus edition! Dragon Ball introduces a young monkey-tailed boy named Goku (a wry update of the classic Chinese "Monkey King" legend), whose quiet life changes when he meets a girl named Bulma who is on a quest to collect seven "Dragon Balls."

But the precious orbs are scattered all over the world, and Bulma could use the help of a certain super-strong boy... Legend has it that if all seven of the precious orbs called “Dragon Balls” are gathered together, an incredibly powerful dragon god will appear to grant one wish. Unfortunately, the orbs are scattered across the world, making them extremely difficult to collect. Enter 16-year-old Bulma, a scientific genius who has constructed a radar to detect the exact locations of the Dragon Balls. She’s on a mission to find all seven orbs, but first she must convince young Son Goku to join her on her quest.
