The invention provides an assembly comprising at least one substrate being bonded to a structural adhesive wherein the structural adhesive is obtained by curing a precursor comprising a cross-linkable polymer, wherein a surface area of the substrate bonded to the structural adhesive comprises at least one metal, said surface area being treated with a liquid activator. User interactions with a computer program are stored. The server application formats the received messages and communicates to the sensor nodes and in turn also receives responses from the sensor nodes and communicates them back to the IM client. The rear panel includes a pair of openings through which the band of the wrist-watch can be extended to surround the package with the walletbillfold therein. A second oxic gas is introduced either into the pressurised recycle stream or into a further pressurised stream of aqueous liquid flowing into the same volume.
