In a method for detaching a charge which is stuck to the inner wall of a grinding pipe, the grinding pipe is rotated in a targeted manner such that the charge that is stuck is removed from the inner wall of the grinding pipe as a result of multiple modification of the rotational speed of the grinding pipe and, optionally, as a result of abrupt braking of the grinding pipe. The fingerprint sensing system includes: at least one sensor; at least one display device; at least one application processor; and at least one secure enclave processor. The methods comprise providing an amine and providing a metathesized natural oil. The UE may receive MBMS traffic from the target cell using the MBMS control information received from the notification cell. The stack may also contain at least one hydrogen-permeable regenerated cellulose film and at least one hydrogen permeable hydrocarbon film such as polypropylene. The private computer platform signs and hashes the billing charge using a private key of a public-private endorsement key pair to create a signed metric report.
