A dynode constituting an electron multiplier or a photomultiplier is provided with eight rows of channels each defined by an outer frame and a partitioning part of the dynode. At least three measurements of instantaneous queue size are obtaining and utilized to determine a traffic pattern’s relative shape, absolute level, and absolute context over a more extended time period. An optical coupler such as an optical circulator or a curved grating is used to direct the reflected wavelengths to a separate output path. 3V, while the first memory 22 by a second voltage of 5V. The known frames have an encapsulated source site identifier used for media access control address learning. The pharmacologically active detergent compositions can additionally include anti-inflammatory agents, analgesics, dispersion or anti-dispersion agents and pharmaceutically acceptable excipients.
