Finally the integrated circuit has a first voltage level controller provided to split the voltage needed to program the NPN-transistor over the first and at least second currentfeeding circuit.
Under anaerobic conditions (where oxygen is absent) they metabolise the fuel by feeding off it and in doing so produce natural chemical reactions that produce a current.
在厌氧条件下(比如缺氧的地方)通过取食产生新诚代谢并以此引起化学反应产生电流。

But a study in the journal Current Biology suggests that feeding birds in winter can influence their course of evolution.
