A system and method for finding a business entity in a database that matches input data. The sensor detects interaction of probe devices with the electronic circuitry for the purpose of reverse engineering the electronic circuitry. The discontinuities bound areas sized to accommodate standard refrigeration units, and a cutting tool may be easily guided along these discontinuities to form a space wherein the refrigerator may be fit when the bulkhead is mounted to the trailer wall. The formation of gate marks in the urethane material is avoided by repositioning the end caps after injection to separate the injection gate from the cylindrical cavity. More particularly, the invention relates to single stranded chemically modified oligonucleotides for inhibiting microRNA and pre-microRNA activity and to methods of making and using the modified oligonucleotides.
