Vielfalt sucht Rat : Ratsmitglieder mit Migrationshintergrund in deutschen Großstädten

Deutschland ist ein Entwicklungsland, wenn es um die Repräsentanz von Migrantinnen und Migranten in der kommunalen Demokratie geht. Sie stellen nur knapp vier Prozent der Ratsmitglieder in den deutschen Großstädten. Dabei hat bereits rund ein Drittel der Bevölkerung einen Migrationshintergrund. Von gelungener Integration kann aber erst die Rede sein, wenn Migrantinnen und Migranten auch ganz selbstverständlich in den Parlamenten vertreten sind. Die vorliegende Studie „Vielfalt sucht Rat. Ratsmitglieder mit Migrationshintergrund in deutschen Großstädten“, angefertigt vom Max-Planck-Institut zur Erforschung multireligiöser und multiethnischer Gesellschaften, liefert die empirischen Grundlagen für die überfällige Debatte um die politische Teilhabe von Migrantinnen und Migranten. Eine Studie des Max-Planck-Instituts zur Erforschung multireligiöser und multiethnischer Gesellschaften in Kooperation mit der Heinrich-Böll-Stiftung und gefördert durch die Stiftung Mercator

Design of artificial neural networks for slipper analysis of axial piston pumps

Purpose - The purpose of this paper is to experimentally and theoretically investigate slippers, which have an important role on power dissipation in the swash plate axial piston pumps. Design/methodology/approach - The slipper geometry and working conditions affected on the slipper performance have been analyzed experimentally. The model of the slipper system has been established by original neural network (NN) method. Findings - First, the effects of the slipper geometry with smooth and conical sliding surfaces on the slipper performance were experimentally analyzed. Smooth sliding surface slippers showed a better performance then the conical surface ones. According to the results, the neural predictor would be used as a predictor for possible experimental applications on modeling this type of system. Originality/value - This paper discusses a new modeling scheme known as artificial NNs an experimental and a NN approach have been employed for analyzing axial piston pumps. The simulation results suggest that the neural predictor would be used as a predictor for possible experimental applications on modeling bearing system. © 2009 Emerald Group Publishing Limited.

Peripheral ameloblastoma: a case report

Peripheral ameloblastoma, a rare and unusual variant of odontogenic tumour, comprises about 1% of all ameloblastomas. The extraosseous location is the peculiar feature of this type of tumour, which is otherwise similar to the classical ameloblastoma. An additional case of this infrequent tumour is described on the lingual alveolar mucosa of the right mandibular premolar region in a 60-year-old man. Clinical evidence, microscopic findings, CT imaging and recurrence for this tumour are discussed
