In addition to the primary destruction of brain tissue readily visible at autopsy (permanent track), gunshot wounding to the brain creates a pulsating temporary cavity due to radial expansion along the bullet's track. To determine the maximum extent of this temporary cavitation in brains of victims of gunshots from weapons with low muzzle velocity, we(More)
To determine the value of imaging procedures such as computer tomography (CT) and magnetic resonance imaging (MRI) of the head in providing additional information of forensic relevance, we examined 17 cadavers of human victims of gunshot wounds to the head. Three of the victims briefly survived the gunshot wound. The weapons involved were all guns with low(More)
We have studied binary two-dimensional (2D) mixtures of superparamagnetic colloidal particles interacting through magnetic dipole moments, which were induced by an external magnetic field B. By tuning B the effective system temperature could be widely adjusted. Time-dependent particle coordinates measured by video-microscopy provide radial pair-distribution(More)
In 2001 twelve different ion species – 238 U – were accelerated in the SIS. Altogether 6079 h of beam time were provided for experiments, often with one or more high-energy target experiments and the ESR running in a pulse-to-pulse time-sharing operation mode. Another 350 h were used for accelerator tune-up and development. The total down-time of 266 h (4 %(More)
In the main synchrotron of the FAIR project, SIS100, accelerating voltages up to 450 kV are required. [1,2]. In parallel with the studies on MA cavities conventional ferrite-loaded cavities are studied as an alternative for the needed accelerating system. In ferrite-tuned cavities, the maximum accelerating voltage is most often strongly restricted by the(More)
Experimental studies have shown that diffuse axonal injury is usually induced by positive or negative acceleration mechanisms. In order to determine the reliability of axonal injury (AI) as a marker of this type of traumatic insult, we compared cases of trauma-induced focal cortical hemorrhage without dural involvement (n = 67) with cases of trauma-induced(More)
