which are accompanied by huge bursts of gamma rays. An international team led by Lars Fuhrmann from Bonn’s Max Planck Institute for Radio Astronomy has now for the first time confirmed a link between the gamma bursts and
A source of gamma rays is glued onto a non-magnetic tube (7) located in a ring gap provided by the coils, and tube (7) is fixed to a non-magnetic disk keyed onto the shaft of a small electric motor, so the tube can be rotated in the ring gap. The pref. generator consists of...

The carbon matrix is mounted between two dense materials (3) such as Densimet(RTM: tungsten alloy), so as to stop beta rays, X rays and gamma rays. The materials with good heat conductivity enclose the carbon matrix and the paraffin matrix for stopping the neutron radiation. The dense ...

After listening to some studies about gamma rays applied to vanadia-phosphate semiconductors conducted by Hench and his coworkers, the colonel's question was simple, but at the same time, very inspirational: "If you can make a material that will survive exposure to high energy radiation, can ...
When a fungal ball/aspergilloma is visible radiologically, the diagnosis has been made late. Sometimes weight loss and fatigue are predominant symptoms; pyrexia is rare. Despite the efforts of the mycology community, and significant strides being taken in optimising the care of these patients, ...
