The present invention relates to a supporting structure having function of rod-linkage latching which comprises a connecting unit, a base seat, a base seat hinge, a main hinge, at least one rod-linkage mechanism and at least one rod-linkage latching device. The array may include multiple sections each having at least one array portion, where each section is to receive different significant portions of a digital control value. The method may also include selecting a destination mainframe system and sending a buffer including information from the request from the source mainframe system to the destination mainframe system and establishing, at the destination mainframe system, an IMS DRA connection with the IMS system from the request. The guard may include handles to facilitate installation and removal. The shift activity template describes a worker activity performed during a shift. The novel lubricant compositions comprise the reaction product of a selected group of 5-tert-butyl-4-hydroxy-3-methylphenyl substituted carboxylic acid esters with thiodiethylene glycol and a mono-hydroxy alcohol with a carbon chain length higher than 4 C-atoms.
