Download or read book Catalytic Ammonia Synthesis written by J.R. Jennings and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of catalysis is found in many homogeneous and heterogeneous systems undergoing chemical change, where it effects the rates of approach to the equilibrium state in processes as diverse as those found in the stars, the earth's mantle, living organisms, and the various chemistries utilized by industry. The economies and the living standards of both developed and developing countries depend to varying degrees upon the efficacy of their chemical industries. Con sequently, this century has seen a wide exploration and expansion of catalytic chemistry together with an intensive investigation of specific, essential processes like those contributing to life-supporting agricultures. Prime among the latter must surely be the "fixation" of atmospheric nitrogen by catalytic hydrogenation to anhydrous ammonia, still the preferred synthetic precursor of the nitrogenous components of fertilizers. In each decade contemporary concepts and techniques have been used to further the understanding, as yet incomplete, of the catalyst, the adsorbates, the surface reactions, and the technology of large-scale operation. The contributors to the present volume review the state of the art, the science, and the technology; they reveal existing lacunae, and suggest ways forward. Around the turn of the century, Sabatier's school was extending the descriptive catalytic chemistry of hydrogenation by metals to include almost all types of multiple bond. The triple bond of dinitrogen, which continued to be more resistant than the somewhat similar bonds in carbon monoxide and ethyne, defied their efforts.
Download or read book Sustainable Strategies for the Upgrading of Natural Gas Fundamentals Challenges and Opportunities written by E.G. Derouane and published by Springer Science & Business Media. This book was released on 2005-06-01 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy and feedstock materials for the chemical industry are in increasing demand and, with constraints related to the availability and use of oil, the energy and chemical industry is undergoing considerable changes. In recent years, major restructuring has occurred in the oil, petrochemical, and chemical industry, with increasing attention devoted to the use of natural gas, methane in particular, as a chemical feedstock rather than just as a fuel. The conversion of remote natural gas into liquid fuels or other transportable chemicals is a challenge to industrial catalysis. Few processes exist so far with the major ones involving the conversion of natural gas to synthesis gas by steam reforming, CO2 reforming, or partial oxidation, followed by the syntheses of methanol, hydrocarbons (Fischer-Tropsch synthesis), or ammonia. In this book, a comprehensive overview of the field of processing natural gas is given, through a series of chapters written by leading scientists and engineers in the field. New developments are discussed and current work relevant to the area is shown by a series of recent works by researchers working in this and related fields.
Download or read book Twitter and Society written by Katrin Weller and published by Peter Lang Gmbh, Internationaler Verlag Der Wissenschaften. This book was released on 2013 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its launch in 2006, Twitter has evolved from a niche service to a mass phenomenon; it has become instrumental for everyday communication as well as for political debates, crisis communication, marketing, and cultural participation. But the basic idea behind it has stayed the same: users may post short messages (tweets) of up to 140 characters and follow the updates posted by other users. Drawing on the experience of leading international Twitter researchers from a variety of disciplines and contexts, this is the first book to document the various notions and concepts of Twitter communication, providing a detailed and comprehensive overview of current research into the uses of Twitter. It also presents methods for analyzing Twitter data and outlines their practical application in different research contexts.
Download or read book Environmental Management of Marine Ecosystems written by Md. Nazrul Islam and published by CRC Press. This book was released on 2018-03-09 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem-Based Management (EBM) is one of the most holistic approaches to protecting marine and coastal ecosystems as it recognizes the need to protect entire marine ecosystems instead of individual species. After decades of pollution, habitat degradation and overfishing, now climate change and ocean acidification threaten the health of the ocean in unprecedented way. Environmental Management of Marine Ecosystems illustrates the current status, trends, and effects of climate, natural disturbances and anthropogenic impacts on marine ecosystems. It demonstrates how to integrate different management tools and models in an up-to-date, multidisciplinary approach to environmental management. This indispensable guide provides several case studies from around the world and creates a framework for identifying management tools and their applications in coral reefs, fisheries, migratory species, marine islands and associated ecosystems such as mangroves and sea grass beds. It discusses the physical and chemical compositions of marine ecosystems along with the threats and actions needed to protect them. The application of model framework to several contemporary management issues include the modelling of harmful algal bloom dynamics, understanding the dispersal of sea lice, and the possible impacts on intertidal communities of the provision of novel offshore habitat. The results of extensive research by an international team of contributors, the Environmental Management of Marine Ecosystems is designed to inform scientists, practitioners, academics, government and non-government policymakers on the particularities of marine ecosystems and assist them in understanding the EBM approaches in means of mitigation and adaptation of human activities that result in sustainability. These practices will help change the current methodologies used for resource assessment and the future regulations of marine resources.

The day-to-day innovations seen in the field are, in great part, due to the integration of many scientific bases with complex technologic advances. The aim of this reference book, Basic Sciences of Nuclear Medicine, is to provide the reader with a comprehensive and detailed discussion of the scientific bases of nuclear medicine, covering the different topics and concepts that underlie many of the investigations and procedures performed in the field. Topics include radiation and nuclear physics, Tc-99m chemistry, single-photon radiopharmaceuticals and PET chemistry, radiobiology and radiation dosimetry, image processing, image reconstruction, quantitative SPECT imaging, quantitative cardiac SPECT, small animal imaging (including multimodality hybrid imaging, e.g., PET/CT, SPECT/CT, and PET/MRI), compartmental modeling, and tracer kinetics.
Download or read book An Introduction to Botanical Medicines written by Antoine Al-Achi and published by Bloomsbury Publishing USA. This book was released on 2008-08-30 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: For those who want to make educated decisions about whether, and when, to use natural products, this text explains the most current scientific evidence of the roles that plants can play in our health: how they can prevent, modify, or treat disease. Since antiquity, humans have used botanicals to treat various conditions affecting their organ systems, and this book is built around explaining which plants may be used for major ailments affecting the various systems. The increasing availability of botanicals on the market, intended to be used as dietary supplements for health, has been fueled by the public's demand for a more natural approach to healthcare. Unfortunately, much of the information fed to the public on alternatives is based on anecdotal evidence (case stories), the advice of friends, or media features that often do not stand up to standards for scientific evidence. In this book Al-Achi explains current research and science that exists - or remains lacking - for the various botanicals as healthcare products. He also details the potential misuse and the dangers of some herbal formulas. Photographs of 62 medicinal plants are included.

Because of its evidentiary approach, this book may serve also as a text for introductory college courses in the field of botanical medicine, or as a supplemental general text for an alternative and complementary medicine course. The history leading to the use of botanicals in healthcare is described, as are botanicals used in the treatment of cancer, cardiovascular disease, endocrine system disorders such as diabetes, gastrointestinal problems, men's and women's specific disorders, infections, chronic pain, psychological disorders such as anxiety and depression, and other health issues.
Download or read book Toxicology in Transition written by Gisela H. Degen and published by Springer. This book was released on 2011-12-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume contains the main papers presented at the 1994 EUROTOX Congress, Basel, Switzerland, August 21-24, 1994. Toxicology has become a less descriptive science because more importance has been placed on the mechanisms underlying toxic effects. This is reflected in symposia and workshops devoted to species differences in organ toxicity, receptor-mediated toxicity and stereochemical effects of xenobiotics. Recent progress in the fields of immunotoxicology, ecotoxicology, and neurotoxicology is highlighted and documented together with the present discussion on harmonized regulatory guidelines.

This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the oil embargo, in the winter 1973174, parts of Western Europe present ed an almost war-like aspect on Saturdays and Sundays: no traffic on the high ways, no crowds at ski resorts and other weekend entertainment places, no gaso line at the pumps. Living and teaching then in that part of the world, and discussing the situa tion with our students, we came to the conclusion that it would be timely to col lect the fine chemistry already known at the time in the field of conversion of coal to gasoline and other chemicals, and by this way help to draw the attention to this important alternative to crude oil. The idea of this book was born. The energy shock of the early seventies has been healthy and of great conse quences in chemistry. Large amounts of research money have been put to work since, and our knowledge of the possibilities and limitations of coal-based chemistry has increased enormously. During several years it appeared inap propriate to write a monograph about a topic which was in the midst of such an impetuous development. Nevertheless, we collected, and critically selected, the upcoming work as it appeared in the literature, and also tried to provide some modest input ourselves. Now, ten years later, the situation seems to be settled to a certain degree.
