An exerciser includes a right pedal and a left pedal, both of which are alternatively operated by the user to drive the right and left links so as to move the right and left swinging arms respectively, such that the hands and feet of the user are exercised. The methods employ a heat transfer test assembly including an outer tube member, a heating rod positioned within the outer tube member, a ribbed tube sleeve fitted over the heating rod and thermocouples for sensing the wall temperature of heating rod. The method can further include the step of\u2014in response to measuring the parameter\u2014selecting a scanning rate of the multi-mode communication device for a second, different network that interacts with the multi-mode communication device. This requires a new dedicated descriptor, carried in the Elementary Stream Descriptor. By providing an O2 gas mixture having a lower concentration of O2, the present invention significantly mitigates the risk of surgical fires. The compositions comprise oligonucleotides, targeted to nucleic acid encoding AP-2 alpha.
