Granule comprising lipid powder particles having a microporous structure. The device incorporates a Supervisor function for controlling access to information stored in a storage medium of the device. It also provides a consolidated editing tool for identifying clip-shape edit points that are near a cursor’s location as the cursor moves from track to track in the composite display area and collectively selecting the identified clip-shape edit points along multiple track in order to receive an edit operation to collectively perform on said the clip-shapes of the identified edit points. The organic electroluminescent device is characterized in that at least one of organic layers constituting the device is a light-emitting layer containing a host compound and a phosphorescent compound of the general formula:and the at least one organic layer has a film surface density of 1. Each slice is sent to respective further devices accessible by the server such that no single further device receives sufficient slices to reconstruct the encryption key.
