A high performance piezoelectric actuator. The reaction is typically carried out in the presence of an acid catalyst. In another embodiment, the densifiable product further includes fibers having coarseness greater than about 22 mg100 m. Similarly, the sample containers are equal in number to the conduits, with each sample container connected to an individual conduit opposite the connection to the shaft. These conveyor contact rails inhibit vibrations and impacts acting on the semiconductor wafers when the sealed container body is conveyed by a conveyor. In one embodiment, by recognizing time dimensions with distinctive activity patterns, systems can better present overviews of activity over time.
