Ammonia is one of the most important inorganic basic chemicals, not only for the manufacture of fertilizers (85%) but also for the production of plastics, fibers, explosives, and intermediates for dyes and pharmaceuticals. It is an essential reaction component for the synthesis of numerous organic chemicals used as solvents and intermediates. The book provides a practical and up-to-date account of the product properties, synthesis and reaction mechanisms, including catalysis and commercial catalysts, modern production technology for different feedstocks, quality specifications and environmental health and safety aspects, uses and economic data of this important commodity chemical. It also di...
This book takes a scientific approach to railways, and is intended to be of use to railway managers, economists and engineers, consulting economists and engineers, students of schools of engineering, transportation and management. This revised, updated and expanded edition is still rooted in engineering but now provides a much broader context, including policy and legislation, planning and management, and forecasting demand.
Integrating molecular physics and information theory, this work presents molecular electronics as a method for information storage and retrieval that incorporates nanometer-scaled systems, uses microscopic particles and exploits the laws of quantum mechanics. It furnishes application examples employing properties of distinct molecules joined together to a macroscopic ensemble of virtually identical units.
For anyone needing to keep up to date with all the latest research in the field of membrane computing, this book will come as a breath of fresh air. It is the extended post-proceedings of the 8th International Workshop on Membrane Computing, held in June 2007. A total of 27 revised papers are presented. All of them have been through two rounds of reviewing. Special attention has been paid to the interaction of membrane computing with biology and computer science.
This book constitutes the thoroughly refereed post-conference proceedings of the 13th International Conference on Membrane Computing, CMC 2012, held in Budapest, Hungary, in August 2012. The 21 revised selected papers presented together with 6 invited lectures were carefully reviewed and selected from 25 papers presented at the conference. The book also deals with membrane systems, also called P systems, which are distributed and parallel algebraic models processing multisets of objects in a localized manner (evolution rules and evolving objects are encapsulated into compartments delimited by membranes), with an essential role played by the communication among compartments and with the environment.
This book constitutes the thoroughly refereed post-workshop proceedings of the 10th International Workshop on Membrane Computing, WMC 2009, held in Curtea de Arges, Romania, during August 24 to 27, 2009 under the auspices of the European Molecular Computing Consortium (EMCC) and the Molecular Computing Task Force of IEEE Computational Intelligence Society. The 22 revised full papers presented together with 10 invited papers went through two rounds of reviewing and improvement. The papers in this volume cover all the main directions of research in membrane computing, ranging from theoretical topics in mathematics and computer science to application issues; the invited lectures present fundamental contributions to membrane computing; thus highlighting important directions of current research in this area.
In a rapidly changing world, with increasing competition in all sectors of transportation, railways are currently restructuring their planning, management, and technology. As commercial and pricing policies change and new methods of organization are introduced, a more entrepreneurial spirit is required. At the same time, new high-speed tracks are being constructed and old tracks are being renewed, magnetic levitation trains are in operation, hyperloop systems are being planned, high-comfort rolling stock vehicles are being introduced, logistics and combined transport are being developed. Awareness of environmental issues and the search for greater safety attribute a new role to the railways ...

From the author of The Oranging of America comes this inspiring true story about an American family. Rocky takes over a family, at the age of 103, and shows them how to survive.
This textbook focuses specifically on the combined topics of irrigation and drainage engineering. It emphasizes both basic concepts and practical applications of the latest technologies available. The design of irrigation, pumping, and drainage systems using Excel and Visual Basic for Applications programs are explained for both graduate and undergraduate students and practicing engineers. The book emphasizes environmental protection, economics, and engineering design processes. It includes detailed chapters on irrigation economics, soils, reference evapotranspiration, crop evapotranspiration, pipe flow, pumps, open-channel flow, groundwater, center pivots, turf and landscape, drip, orchards, wheel lines, hand lines, surfaces, greenhouse hydroponics, soil water movement, drainage systems design, drainage and wetlands contaminant fate and transport. It contains summaries, homework problems, and color photos. The book draws from the fields of fluid mechanics, soil physics, hydrology, soil chemistry, economics, and plant sciences to present a broad interdisciplinary view of the fundamental concepts in irrigation and drainage systems design.
