A software tool and methods for preventing software modifications from invalidating previously passed integration test cases is provided. Thereafter, an electrode stack is placed in the housing and then, the first indentation is indented further in a direction towards the inside of the housing by a applying a force on the housing laterally to the first indentation, during which the electrode stack becomes fixed in the housing. Each node in the convergecast tree is associated with a hop-count to the base-station through a specific branch and each node can generate zero or more packets to transmit. This rotation is accomplished by at least one drive motor which is fixed on a frame of the printing machine. The method comprises surgically removing a damaged cartilage from a patient and inserting the hybrid construct into the cavity generated after the foregoing surgical intervention.
