A magnetic tunneling junction memory cell is formed with a keeper structure on its upper conductor. The glass substrate comprising a surface region and a peripheral edge region surround the surface region. The method further senses if a synchronizer actuator-on fault has occurred, then determines which synchronizer is faulted if an actuator-on fault has is detected. Further, a low-pass filter is applied to the string containing multiple first values and multiple second values, and the output of the low-pass filter is used to determine the location of the main content within the web page. The lateral nozzles are associated with at least one pair such that the nozzles of the pair are aligned in a given axis and arranged opposite to each other, and, between the two aligned nozzles of the pair, a single controllable plug device is provided, connected to said generator and capable of controlling the flow of gases through said nozzles in both directions. The particulate matter has preferably been contacted, complexed or reacted with a tethering agent.
