A cooling arrangement for supplying a first cavity with a cooling gas, in particular in a gas turbine of a power plant, includes a cooling-gas passage which is formed in a first component and connects the first cavity to a second cavity. A waveform generator includes a first transistor having a drain electrode, a gate electrode, and a source electrode. ZcytoR14 is a common receptor for IL-17A and IL-17F. The N+1 actuators receive the real control inputs and subsequently provide an actual virtual control input to the plant. In a modification, strengthening crossbars are formed between adjacent flanking walls.
