Isaiah Berlin was born a century ago. One of the most celebrated British thinkers of the twentieth century, he was a tireless champion of freedom and diversity against control and conformity. His generous, open vision of life is displayed with special immediacy in his brilliant pen-portraits of contemporaries, Personal Impressions, in which he sees the point of radically differing personalities, enters into their distinctive outlooks, and describes his encounters with them, in arrestingly ...

Thema dieses Buches sind die Fragilitätsfrakturen des Beckens aus interdisziplinärer Sicht. Als ein Indikationsfaktor für Osteoporose zeigen Fragilitätsfrakturen des Beckens regelhaft ein typisches Frakturmuster mit der Gefahr einer Frakturprogression und einer konsekutiven Instabilitätszunahme. In der Diagnostik fokussiert die erweiterte Bildgebung (CT und/oder MRT) den hinteren Beckenring. Therapeutisch ist das primäre Behandlungsmanagement eine zweiwöchige konservative Therapie, wohinge...

Ab dem Frühjahr 1854 begann der Augustinermönch Gregor Mendel (1822–1884) mit der Auswahl geeigneter Sorten der Gartenerbse (Pisum sativum) für seine Kreuzungsversuche, die er regelmäßig bis 1863 im Klostergarten in Alt-Brünn in Mähren durchführte. Die exakten Hybriden-Experimente mit dem Pflanzenmaterial sollten jene werden, die ihn zum Begründer einer ganz neuen intellektuellen Forschungsrichtung innerhalb der modernen Biologie nach 1900 machten. Das vorliegende Buch beinhaltet neben ein...

Plants are composed of 17 essential and at least 5 beneficial elements, and these must be taken up as metal or nutrient ions to allow for growth and cell division. Much effort has been devoted to studying the physiology and biochemistry of metals and nutrients in plants. The aspect of cell biology, however, is an emerging new field and much needs to be learned about sensing, long-distance communication within plants, and cellular signal transduction chains in response to environmental stre...
