A composition comprising: an organic chemical having a chemical group having a dipole moment of at least about 1. Further embodiments include a method that includes switching circulation of a lubricant between a first filter and a second filter in response to an angular position of a valve disposed in a valve block integral to a machine block having moving components lubricated by the lubricant. Further in addition, it is another object to provide an electric appliance which has a light emitting element with low drive voltage. Moreover, systems are disclosed that are capable of automatically determining whether to encrypt a file based on the generated encryption rules. The solution contains a high concentration of the amine carboxylate VCI, thus facilitating, on application of the coating, a dry film coat containing an effective corrosion-inhibiting amount of the amine carboxylate VCI.
