The present invention relates to an inflatable ball, in particular a soccer ball, having an outer shell comprising a plurality of panels, wherein the panels are interconnected by seams and each panel comprises at least one pseudo-seam extending over at least a part of the outer surface of the panel. The threshold signal used to detect multipath noise is varied depending on reception conditions. Additionally the secondary catch would also provide some additional protection by holding the tong assembly together in the event of a failure of certain tong components. According to the present invention the memory management system 14 is arranged for removing classes which do not have any instantiated objects which can be reached in the present state of the program even if the classloader is still reachable. Occurrence of intergranular stress corrosion cracking in metallic component materials in contact with reactor cooling water is suppressed by injecting zirconium hydroxide and hydrogen into the reactor cooling water to decrease the electrochemical corrosion potential of the metallic component materials. In the event of an external refresh command, a control device causes, after the refresh operation, the state of the memory banks to be reestablished, in particular, the word line whose address was stored in the register to be reactivated.
