Divided into two parts, the volume first covers various disparate protocols relating to the direct detection and quantification of nitric oxide, including techniques which detail how to image real time in vivo generation of nitric oxide, quantify nitric oxide production in the rat brain, and the detect ultralow levels of nitric oxide in the pM range, and the book then continues with a section on techniques designed to either inhibit or enhance nitric oxide, with an aim to achieve therapeutic gain, featuring the inhibition of the nitric oxide synthase enzymes using viral, shRNA delivery systems to prevent cardiovascular dysfunction, peripheral neuropathy, and graft rejection. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and easy to use, Nitric Oxide: Methods and Protocols examines numerous complex methodologies detailed in each chapter and proves to be an invaluable resource for anyone with an interest in nitric oxide research.

Nitrogen Capture: The Growth Of An International Industry (1900-1940)

by Anthony S. Travis

This monograph provides an account of how the synthetic nitrogen industry became the forerunner of the 20th-century chemical industry in Europe, the United States and Asia. Based on an earlier SpringerBrief by the same author, which focused on the period of World War I, it expands considerably on the international aspects of the development of the synthetic nitrogen industry in the decade and a half following the war, including the new technologies that rivalled the Haber-Bosch ammonia process. Travis describes the tremendous global impact of fixed nitrogen (as calcium cyanamide and ammonia), including the perceived strategic need for nitrogen (mainly for munitions), and, increasingly, its role in increasing crop yields, including in Italy under Mussolini, and in the Soviet Union under Stalin. The author also reviews the situation in Imperial Japan, including the earliest adoption of the Italian Casale ammonia process, from 1923, and the role of fixed nitrogen in the industrialization of colonial Korea from the late 1920s. Chemists, historians of science and technology, and those interested in world fertilizer production and the development of chemical industry during the first four decades of the twentieth century will find this book of considerable value.

Nitrogen Deposition, Critical Loads and Biodiversity

by Mark A. Sutton Kate E. Mason Lucy J. Sheppard Harald Sverdrup Richard Haeuber W. Kevin Hicks

This volume brings together extended reviews and papers of new scientific research on atmospheric nitrogen deposition impacts globally. While there is a wealth of evidence on the magnitude, components and effects of nitrogen disposition on floral biodiversity in Europe and North America, there is an obvious lack of information on impacts on above- and below-ground fauna, and all impacts in other parts of the world, with no clear overview of how the different strands of evidence fit together. This overall synthesis is targeted at the international conventions, but is equally readable for scientists, environmental managers, conservation agencies and policy makers. 'This timely book highlights the global nitrogen deposition problem. Major regions of the world are exceeding sustainability thresholds for adverse effects on ecosystem function and biodiversity. This highlights the importance of ongoing work, including under the Convention on Biological Diversity, in developing indicators and monitoring nitrogen deposition effects to enable appropriate measures. This book presents a milestone towards this global goal as the international community works toward meeting the Aichi Biodiversity Targets, especially Target 8: "By 2020, pollution, including from excess nutrients, has been brought to levels that are not detrimental to ecosystem function and biodiversity". Braulio Ferreira de Souza Dias, Executive Secretary, Convention on Biological Diversity "This key volume highlights the global challenge to reduce atmospheric nitrogen pollution resulting from energy production, transport and agricultural activities. It takes forward the agenda recently launched in the UNEP commissioned report 'Our Nutrient World". Dr. Anjan Datta, UNEP.
