In a control rod having a plurality of elongated members for absorbing neutrons within a nuclear reactor to control a nuclear reaction, each elongated member may include a cylindrical inner capsule configured to contain neutron absorbing material therein. This state component can be invoked by the program or model itself, thereby making state a first-class citizen. Subsequently, the hardened photoresist layer is etched so as to turn the photoresist layer into a predetermined edge profile. The fan is fixedly mounted on the fan holder and faces towards the channels of the heat sink. The invention is also directed to a pharmaceutical composition comprising a compound according to formula and a pharmaceutically acceptable carrier, and to methods for providing anesthesia in mammals by administering such a pharmaceutical composition. The turbine blade is formed essentially from carbon-fiber-reinforced carbon, at least the blade leaf region having a blade outer wall with carbon-fiber-reinforced carbon, the blade outer wall being surrounded by a protective layer.
