A simple micromechanical method has been used to directly measure the force of contraction in single mammalian phagocytes (blood granulocytes) during engulfment of large yeast pathogens. Both the time course of cell spreading over the yeast particle and increase in cell body contractile force were quantitated at three temperatures in the range of 23-35(More)
We designed an auxiliary power supply for medium voltage MMC-converters with system voltages up to 36 kV<sub>rms</sub>. The system supplies up to 250 W power and is based on a two-stage design. The first stage is an inductive power transfer system that isolates against the system voltage. It is connected to a low voltage DC-supply on ground potential, and(More)
