An ink composition is provided which has excellent initial filling characteristics and continuous printing stability even in the case of an ink composition which is almost not deaerated or an ink composition which is not deaerated at all. The first module determines an expected response of crankshaft speed due to combustion within a cylinder of the engine. The object illumination beam is directed onto an object, and a portion of the beam is reflected back to the beamsplitter, which combines the phase-shifted reference beam and object illumination beam substantially coaxially. When the source server determines that the potential matching listing received from the provider server is a matching listing, the source server transmits to the provider server the enhanced listing with an identifier provided by the provider server as an indication to the provider server to update the enhanced listing on the provider server with the enhanced content. The node is adapted to estimate at least one safety degree relating to the node, to select at least one security algorithm of the one or more security algorithms, depending on the estimated safety degree; and to activate the at least one security algorithm. The drive shaft has an interruption that redirects a fluid flowing from the hydraulic pump to the generator when the drive shaft is rotated.
