A streaming engine and method includes a plurality of input types configured to pass one of samples and frames from an input stream. Each stud is releasably attached to the chassis through the lower side of the upper. The identification of the selected network node is achieved through binding of a session identifier associated with the end user to the selected network node. Communication between all operator units of the sub-group and the interface means is effected on a single communication line. A nonstirred surface reactor is then formed by stacking the plurality of coated coarse substrates into a heap or placing the plurality of coated coarse substrates into a tank so that the void volume of the reactor is greater than or equal to about 25%. The first dielectric plug has a layer of a first dielectric material and a layer of a second dielectric material formed on the layer of the first dielectric material.
