A nucleic acid includes the 5\u2032 untranslated region, a virus protein-coding region including the NS3 protein coding sequence, the NS4A protein coding sequence, the NS4B protein coding sequence, the NS5A protein coding sequence, and the NS5B protein coding sequence, and the 3\u2032 untranslated region of the HCV J6CF genome in that order from the 5\u2032 to 3\u2032 direction. A first inverted cone having a first base angle is defined above a first site, a second inverted cone having a second base angle is defined above a second site. A peer-to-peer computer network is also provided based upon geographically bounded regions, the peer-to-peer computer network can be used to share electronic documents. A platform specific executable is received from the build engine and is stored in an application store to make the platform specific executable available for downloading to the device. The present invention further relates to a wind turbine including such a wind turbine blade and to a method of operating a wind turbine including such a wind turbine blade.
