Een baby met een onduidelijk geslacht
In a neonate with ambiguous genitalia, physical examination revealed a phallus. Ultrasonography showed a vagina and uterus, but no gonads. Because of severe undervirilisation in the presence of a uterus, probably due to 46,XY gonadal dysgenesis, parents were advised female sex assignment. When after a few weeks the phallus had increased in size, abdominal laparoscopy showed an underdeveloped uterus. Gonadal biopsy confirmed gonadal dysgenesis. Sex assignment was reconsidered and changed into the male gende

Development of Radiation Hard Semiconductor Devices for Very High Luminosity Colliders
The requirements at the Large Hadron Collider (LHC) at CERN have pushed the present day silicon tracking detectors to the very edge of the current technology. Future very high luminosity colliders or a possible upgrade scenario of the LHC to a luminosity of 10 cms will require semiconductor detectors with substantially improved properties. Considering the expected total fluences of fast hadrons above 10 cm and a possible reduced bunch-crossing interval of 10 ns, the detector must be ultra radiation hard, provide a fast and efficient charge collection and be as thin as possible.\\ We propose a research and development program to provide a detector technology, which is able to operate safely and efficiently in such an environment. Within this project we will optimize existing methods and evaluate new ways to engineer the silicon bulk material, the detector structure and the detector operational conditions. Furthermore, possibilities to use semiconductor materials other than silicon will be explored.\\ A part of the proposed work, mainly in the field of basic research and defect engineered silicon, will be performed in very close collaboration with research teams working on radiation hard tracking detectors for a future linear collider program
