A coherent body of wet crushed ice is pumped along a pipe. In particular, the invention relates to methods for assaying a sample for one or more nucleic acid targets in a single reaction based on the distinct melting temperatures or melting profiles of primers andor probes. The update GARP generating unit transmits a GARP and thereby updates the ARP tables of the communication devices on the same network, in order to solve a problem in which communication is interrupted. The suspension may further include a torsion bar extending between and coupled to the first and second arms.
