The invention provides a decomposable resin composition, which is stable at the time of use and which quickly decomposes when discarded. The protein, termed FCWP1, demonstrated significant antifungal activity against several fungal species. A single main bus control amplifier tightly regulates the power bus to a main bus voltage set-point and controls charging and discharging of all batteries to prevent charging of one battery at the expense of another battery. The pulse generator is configured to receive, for a first channel, the optical signal and a clock signal. A receiving unit receives a response message including registration information and connection information from the server.
