Recently, a wall was built in eastern Germany. Made of steel and cement blocks, topped with razor barbed wire, and reinforced with video monitors and movement sensors, this wall was not put up to protect a prison or a military base, but rather to guard a three-day meeting of the finance ministers of the Group of Eight (G8). The wall manifested a level of security that is increasingly commonplace at meetings regarding the global economy. The authors of Shutting Down the Streets have directly observed and participated in more than 20 mass actions against global in North America and Europe, beginning with the watershed 1999 WTO meetings in Seattle and including the 2007 G8 protests in Heiligendamm. Shutting Down the Streets is the first book to conceptualize the social control of dissent in the era of alterglobalization. Based on direct observation of more than 20 global summits, the book demonstrates that social control is not only global, but also preemptive, and that it relegates dissent to the realm of criminality. The charge is insurrection, but the accused have no weapons. The authors document in detail how social control forecloses the spaces through which social movements nurture the development of dissent and effect disruptive challenges.

During the Middle Ages, rulers from different regions aspired to an idea of imperial hegemony. On the other hand, there were rulers who deliberately refused to be "emperors", although their reign showed characteristics of imperial rule. The contributions in this volume ask for the reasons why some rulers such as Charlemagne strove for imperial titles, whereas others voluntarily shrank from them. They also look at the characteristics of and rituals connected to imperial rule as well as to the way Medieval empires saw themselves. Thus, the authors in this volume adopt a transcultural perspective, covering Western, Eastern, Northern and Southern Europe, Byzantium and the Middle East. Furthermore, they go beyond the borders of Christianity by including various caliphates and Islamic "hegemonic" rulers like Saladin.

Diplomarbeit aus dem Jahr 2001 im Fachbereich Umweltwissenschaften, Note: 1.3, Bergische Universitat Wuppertal, Sprache: Deutsch, Abstract: Zur Charakterisierung, Qualitatsuberprufung, Produktionssteuerung und Optimierung einer vielzahl industrieller Guter und Prozesse ist die Kenntnis von Partikelgrosse und Partikelform von entscheidender Bedeutung. Diese Eigenschaften beeinflussen in hohem Masse das Verhalten eines Feststoffes. Schon beim Gewinnungsprozess muss eine bestimmte Partikelgrosse erreicht werden, um eine reibungslose Weiterverarbeitung und die angestrebten Qualitatsmerkmale des Endproduktes zu erzielen. Aufgrund wachsender Qualitatsanforderungen mussen diese Merkmale von Schuttgutern immer haufiger, reproduzierbarer und quantitativ exakter ermittelt werden. Dabei stosst die traditionelle Siebanalyse wegen ihres hohen Zeitaufwandes und ihres geringen Auflosungsvermogens zunehmend an ihre Grenzen. Zudem beinhaltet sie Nachteile, wie z.B. die Ungenauigkeiten der Siebmaschenweiten, die aufwendige Reinigung und den Ersatz beschadigter Siebe. Daher werden Siebanalysen immer haufiger durch optische Messverfahren ersetzt. Thema dieser Arbeit ist die Untersuchung und Weiterentwicklung eines optischen Partikelmessgerates, des Camsizer, dessen Messprinzip auf der Technik der digitalen Bildverarbeitung beruht. Die Siebanalyse ist traditionell immer noch die haufigste Methode der Partikelgrossencharakterisierung der Anwender. Um diesen das Umsteigen auf neuere Verfahren zu erleichtern, wird angestrebt, die Messergebnisse von Siebanalyse und optischen Verfahren vergleichbar zu gestalten. Deswegen wird das neue optische Verfahren der Moglichkeit der Partikelcharakterisierung mittels Siebanalyse kritisch gegenubergestellt, wobei auch die Moglichkeit einer Siebungssimulation mit digitaler Bildverarbeitung erortert wird. Ein weiteres Thema dieser Untersuchung ist das Entwickeln einer neuen Software-Edition, die die Moglichkeiten der Korngrossen- und Kornformanalyse na
