A slew rate control system for a circuit includes a temperature sensitive device generates a temperature signal. Upon start-up of a sniffer, a first quote of Platform Configuration Register values in a Trusted Platform Module utilized by the sniffer is obtained, wherein the first quote comprises a list of starting values in the PCRs and is signed by the TPM and stored in a packet log. Conditioned media obtained using epigonal cells from bonnethead sharks and lemon sharks demonstrate strong anti-tumor activities. The step of detecting also includes generating a first signal and a second signal in response to the electrical signal, where the second signal differs from the first. The data acquisition system is operably connected to the one or more ED detectors andor the one or more EI detectors.
