A receiver receives information. A first media member has a plurality of alternating upstream and downstream folds and a wall connecting the folds. Next, OHTL are added to the area in order to produce enough rapidly sinking and refractory particulate matter to sequester carbon dioxide above the level of carbon dioxide sequestration that exists before the addition of OHTL. The rotational damper is radially displaceably mounted and during the damping action is pressed by the actuating member against a retaining element.
