A medical electrode provides enablement for simultaneously connecting a plurality of medical electrical monitoring or testing instruments at a selected single location on a patient’s body. The method includes the steps of creating the plurality of virtual communities based on the resources accessed or actions taken by the plurality of users, keeping track of each of the plurality of user’s resources accessed or actions performed, and enabling the activity based on the resources visited and actions performed by each of the plurality of users. A silicon single crystal is pulled by the Czochralski method and processed to form a polished monocrystalline silicon substrate wafer. Further, a rate of motion of the axial traverser sub-assembly is coupled to a speed of rotation of the support.
