Abstract: A ski boot (1) includes a base frame (2) for receiving a foot of a skier; a rigid sole (3) connected to the base frame (2); a shaft (4) for receiving a lower leg part of the skier, the shaft (4) being angularly variably connected to the base frame (2); and a traction element (12). The traction element is attached to the sole (3) and/or in a toe area of the base frame (2) and extends from there to a heel area of the sole (3). In the heel area, the traction element (12) is deflected towards the shaft (4) and is then attached to the shaft (4). By inclining the shaft (4) towards a toe region, the traction element (12) can be tensioned and, in particular, traction can be exerted on the sole (3) and/or the toe region.

Abstract: A method for operating a gas and steam turbine plant is provided. In the plant, the flue gas that escapes from a gas turbine is routed through a waste gas steam generator and where a flow medium that is used to drive a steam turbine is conducted in a flow medium circuit that includes several pressure stages. At least one of the pressure stages has an evaporator circuit with a steam collection drum that has a plurality of downpipes connected to the steam collection drum and a plurality of rising pipes downstream of the downpipes that are likewise connected to the steam collection drum and are heated by the flue gas in the waste heat steam generator. The height of the fluid column formed by the flow medium in the downpipes is monitored and a transient dry operation of the evaporator circuit can thus be detected and safeguarded against.
