A method for fault tolerance and fault recovery in multiprocessor systems that concurrently manage queues is disclosed. According to the invention, a bushing in the form of a half-liner having a large support angle is inserted in the bearing. The body has a pocket at each of the two selvedges. A communication network is coupled to the originating web server. The auxiliary heater allows increased read lengths and shorter run times than existing capillary electrophoresis devices. Since each Data Block is composed of the MAC-d PDUs originated from the same logical channel, it is possible to monitor the in-sequence delivery of the data units, resulting in reduction of undesirable queuing delay caused by logical channel multiplexing.
