An article and method for measuring strain using a strain gauge made of a shape memory alloy, and preferably a pseudoelastic alloy, is disclosed. A sub-set of Customer-facing ports of each Aggregation Switch are coupled to the VFL and assigned to the IPC VLAN to enable communication therebetween. A determination is made whether the downhole condition matches a target downhole condition within a set tolerance. The outer surface of the base includes a decorative pattern. The salt can then be adsorbed onto a carrier, such as paint pigments, which can then be applied to the surfaces of aluminum and aluminum alloys. An aromatic aldehyde having an alkoxy group as a substituent on an aromatic nucleus is allowed to react with an organic phosphorus compound intramolecularly having a P\u2014H group or a P\u2014OH group.
