Abstract: A method for operating a wind turbine farm includes a plurality of wind turbines arranged together in a wind turbine farm area. each wind turbine includes a tower, a generator system for generating electric power and a rotor provided with a number of rotor blades on a rotor axis coupled to the electric generator for driving the generator, the rotor being arranged on the tower.

Abstract: A system (20) and method for aerodynamic torsion damping of a wind turbine rotor blade (1) having a wind turbine rotor blade aerofoil with a leading edge (2) and a trailing edge (3). An additional aerofoil (6; 6?) is coupled to the wind turbine rotor blade (1), and has a leading edge (7; 7?) and a trailing edge (8; 8?). The leading edge (7; 7?) of the additional aerofoil (6; 6?) is positioned rearward of an elastic axis (E) of the wind turbine rotor blade (1) and generates lift to counter torsional forces experienced by the wind turbine rotor blade (1) along its length.

Abstract: A medical apparatus for effecting radiation treatment on a pre-selected anatomical portion of an animal body is disclosed. The medical apparatus may include a plurality of treatment channels configured to be positioned adjacent a body tissue and a plurality of delivery channels coupled to a corresponding number of treatment channels. The medical apparatus may also include a plurality of source channels configured to receive one or more energy sources, a tracking channel configured to receive a tracking element, and a connecting element configured to connect each delivery channel with either one of the plurality of sources channels or the tracking channel.
