Autothermer Gegenstromreaktor zur Herstellung von CO-reichem Synthesegas im Hochtemperaturbereich
Die Herstellung von CO-reichem Synthesegas kann mittels der trockenen Reformierung von Methan oder der umgekehrten Wassergas-Shift-Reaktion erfolgen. Zur effizienten Durchführung dieser Reaktionen wird der autotherme Gegenstromreaktor vorgestellt, ein Rohrbündelreaktor, welcher aus einer Vielzahl teilweise katalytisch beschichteter keramischer Rohre besteht. In der Wärmetauscherzone wird die Vorwärmung der kalten Edikte mit Hilfe des heißen Produktstroms auf Reaktionstemperaturen über 1000 Grad Celsius erwirkt. Durch gezielte Einspeisung von reinem Sauerstoff in die nachfolgende Katalysatorzone kann die Reaktionswärme der endothermen Synthesen effizient ausgeglichen werden. Konstant h...
Experimentelle Charakterisierung und Modellierung der Rußoxidation
Dieselpartikelfilter werden mittlerweile serienmäßig für die Filtration der Rußpartikel aus dem Dieselabgas eingesetzt. Für die Regeneration der Dieselpartikelfilter ist die Reaktivität des abgeschiedenen Rußes von entscheidender Bedeutung. Durch experimentelle Untersuchungen wurde der Einfluss des eingesetzten Dieselkraftstoffes sowie der gewählten Motorparameter auf die Rußreaktivität und das isotherme Abbrandverhalten des Rußes betrachtet. Des Weiteren wurden die Befunde der isothermen Oxidationsexperimente mit einem Simulationsmodell abgebildet und die Ursachen für die verschiedenen beobachteten Abbrandverhalten mit weiteren experimentellen Methoden wie der Analyse der Entwicklung der BET-Oberfläche im Verlauf der Rußoxidation untersucht. Zusätzlich zur Reaktivität des Rußes wurden auch die Diffusionskoeffizienten von NO in der Dieselpartikelfilterwand und in der Rußschicht ermittelt.
Become a Problem-Solving Crime Analyst
Crime analysis has become an increasingly important part of policing and crime prevention, and thousands of specialist crime analysts are now employed by police forces worldwide. This is the first book to set out the principles and practice of crime analysis, and is designed to be used both by crime analysts themselves, by those responsible for the training of crime analysts and teaching its principles, and those teaching this subject as part of broader policing and criminal justice courses. The particular focus of this book is on the adoption of a problem solving approach, showing how crime analysis can be used and developed to support a problem oriented policing approach – based on the idea that the police should concentrate on identifying patterns of crime and anticipating crimes rather than just reacting to crimes once they have been committed. In his foreword to this book, Nick Ross, presenter of BBC Crime Watch, argues passionately that crime analysts are 'the new face of policing', and have a crucial part to play in the increasingly sophisticated police response to crime and its approach to crime prevention – 'You are the brains, the expert, the specialist, the boffin.'
The Wondrous Story of Anesthesia
Edited and written by an international "who's who" of more than 100 authors, including anesthesiologists, nurse anesthetists, bench scientists, a surgeon, and representatives of industry, this text provides a comprehensive history of anesthesia, unique in its focus on the people and events that shaped the specialty around the world, particularly during the past 70 years when anesthesia emerged from empiricism and developed into a science-based practice.
Criminal Policy in Transition
Criminal Policy in Transition comes along at a time when the literature in criminology is desperately short of “global” perspectives. It helps fill that gap while it presents important new insights into changing penal policy and practice. That it raises as many questions as it seems to answer is one of its great strengths. The authors write knowledgeably about their home societies without being prematurely bounded by comparative criteria. As a result,they develop a complex and uneven image of similarities and differences, of divergence and convergence through time. In this sense the collection offers a model of how international collaborative work should proceed. The book is the product of a workshop held at the International Institute for the Sociology of Law (IISL) in Onati, Spain. The IISL is a partnership between the Research Committee on the Sociology of Law and the Basque Government
The Securitization of Society
Traditionally, security has been the realm of the state and its uniformed police. However, in the last two decades, many actors and agencies, including schools, clubs, housing corporations, hospitals, shopkeepers, insurers, energy suppliers and even private citizens, have enforced some form of security, effectively changing its delivery, and overall role. In The Securitization of Society, Marc Schuilenburg establishes a new critical perspective for examining the dynamic nature of security and its governance. Rooted in the works of the French philosophers Michel Foucault, Gilles Deleuze and Gabriel Tarde, this book explores the ongoing structural and cultural changes that have impacted securi...
Obama Presidential Campaign:TIPPING POINT
This collection explores monetary institutions linking Europe and the Americas in the seventeenth to nineteenth centuries.
Encyclopedia of Sustainable Management
This encyclopedia is the most comprehensive and up-to-date source of reference for sustainability in business and management. It covers both traditional and emerging concepts and terms and is fully international in its scope. More than 700 contributions of internationally renowned experts provide a definitive access to the knowledge in the area of sustainable and responsible management. All actors in the field will find reliable and up to date definitions and explanations of the key terms and concepts of management in this reference work. The Encyclopedia of Sustainable Management represents all aspects of management and business conduct. It takes sustainability as a management concept that gives due credit to the complexity and diverging constraints in which businesses and corporations act today, and it emphasizes and focuses approaches that help ensure that today's management decisions and actions will be the basis for tomorrow's prosperity.
Enforcing Order
Most incidents of urban unrest in recent decades - including the riots in France, Britain and other Western countries - have followed lethal interactions between the youth and the police. Usually these take place in disadvantaged neighborhoods composed of working-class families of immigrant origin or belonging to ethnic minorities. These tragic events have received a great deal of media coverage, but we know very little about the everyday activities of urban policing that lie behind them. Over the course of 15 months, at the time of the 2005 riots, Didier Fassin carried out an ethnographic study in one of the largest precincts in the Paris region, sharing the life of a police station and cru...
