The invention relates to compositions comprising at least one polymer and at least one plasticizer, in which compositions the polymer is semi-crystalline and exhibits a processing temperature equal to or greater than 220 C. The electronic apparatus include: a memory unit which downloads a CAS client from a server and stores the CAS client, a communication unit which receives a message to change a storage location of the CAS client from the server, and a controller which changes a storage location of the CAS client and stores the storage location according to the message received from the server. A multiple chamber system provides for repetitive multi-point sampling, undisturbed metabolic soil processes between sampling, and an essentially airtight sampling chamber operating at ambient pressure. The initiating device is initially in a non-detonation initiating condition, in which it is not capable of accepting the detonation initiating signal. This includes three different services, namely an M-Merchant service, an M-Diaspora service, and an M-Content service.
