I am a striker. I play for Portsmouth in the Premier League, and I play for my country too. My country is Nigeria, in Africa. This is my story. From Africa to Wembley Beautifully illustrated in colour, this story continues the introduction of graphemes and phonemes and builds some more complex sounds.

The book summarises the outcom of a priority research 'Analysis, Modelling and Computation of Multiphase Flows'. The results of 24 individual research projects are presented. The main objective of the research programme was to provide a better understanding of the physical basis for multiphase gas-liquid flows as they are found in numerous chemical and biochemical reactors. The research comprises steady and unsteady multiphase flows in three frequently found reactor configurations, namely bubble columns without interiors, airlift loop reactors, and aerated stirred vessels. For this purpose new and improved measurement techniques were developed. From the resulting knowledge and data, new and refined models for describing the underlying physical processes were developed, which were used for the establishment and improvement of analytic as well as numerical methods for predicting multiphase reactors. Thereby, the development, lay-out and scale-up of such processes should be possible on a more reliable basis.

Friedrich Nicolai, ein bedeutender Vertreter der deutschen Aufklärung, setzte sich vehement gegen Aberglauben, Intoleranz und soziale Missstände ein. Seine scharfe Kritik richtete sich gegen religiöse Unduldsamkeit und kirchliche Probleme. Im Gegensatz zu den neuen Strömungen des Sturm und Drang, die er als individuelle Schwärmerei abtat, verteidigte er die rationalen Prinzipien der Aufklärung. Besonders bemerkenswert sind seine literarischen Konflikte mit Goethe und Schiller, die seine Haltung und den Widerstand gegen den Wandel der Zeit verdeutlichen.
