The present invention relates to a method for inhibiting stress corrosion cracking occurring on steam generator tubes in the secondary side of nuclear power plants and an inhibitor therefor. The circuit board includes an electrical circuit configured for receiving a sensor signal and generating a sensor characteristic in response to the received sensor signal. The second composition ratio is larger than the first composition ratio. A spout projecting radially from the sleeve has an outwardly open passage opening inward into the groove. Bandages, sanitary napkins and the like are useful applications for the intrinsically bactericidal absorbent dressings whose method of manufacture and use are disclosed and claimed.
