An antenna beam controlling system for use in cellular communication systems. A user accesses the document processing device via a user interface, requesting that the configuration of the device be altered. The power factor correction controller may direct the operation of the boost switches with series interleave phasing to perform power factor correction and voltage regulation. The user may be permitted to provide input about specific services offered by specific NSPs. A full length genomic clone for allergen Ara h2 is isolated and sequenced.
