A separator is provided for a fixing device including a rotary fixing member that fixes a toner image on a recording medium and a rotary pressure member pressed against the rotary fixing member to form a fixing nip portion for nipping the recording medium. The methods may include the steps of collecting shed cellular material from one or more plant embryos; obtaining DNA from the shed cellular material; performing a molecular analysis of the DNA; and germinating at least one of said one or more plant embryos. The activation circuit for the first switching element includes a storage capacitor and a DIAC coupled to a control electrode of the first switching element. The vertical interconnects can be transistors, such as surround substrate transistors andor surround gate transistors. Processing electronics are coupled to the anode and process current pulses which are converted into Gaussian pulses, which are either counted as neutrons or integrated as gammas, in response to whether pulse amplitude crosses a neutron threshold. A method of reducing rotor blade weight includes removing material from within a truss area bounded by a platform section, an internal airfoil cooling passage, and an underplatform fillet.
