Brachial as well as lumbosacral plexus avulsion injuries are usually caused by high kinetic traumas, such as car-pedestrian, car and motorcycle accidents or falls from great heights. Traction forces affecting the head and shoulders or extremities pull the spinal nerve sleeves away from the spinal cord and rupture the postganglionic spinal root from the cord. In so called central avulsion injuri...

At the occasion of the OECS conference in Madrid, we give a succinct account of some recent predictions in the spectroscopy of a quantum dot in a microcavity that remain to be observed experimentally, sometimes within the reach of the current state of the art. Light-matter coupling of a single quantum dot in a microcavity has recently enjoyed considerable activity. Led by sustained technologica...

A virtual community called Somos@Telecentros is progressively taking shape in the region (http://www.tele-centros.org) with a specific interest in su...
