Abstract: A system for growing cells comprising a bioreactor chamber for growing the cells, a delivery system delivering a perfusion solution to the bioreactor chamber for perfusion of the perfusion solution through the cells, a dialysis system having a dialyzer, a dialysate for performing a dialysis and a filter for reducing ammonia content in said dialysate, and a controller that circulates the perfusion solution through the dialyzer and the dialysate through the filter.

Abstract: The invention relates to a motor vehicle having three motors, i.e. an electric motor, hydraulic motor, and heat engine, and to a method for managing the energy stored onboard. The three motors (19, 25, 15) are particularly used for driving the vehicle, and are associated with means for storing electrical energy (21), hydraulic energy (28, 29), and fossil energy (18), respectively. The heat engine (15) is arranged so as to be connected in series and so as to recharge the means (28, 29) for storing hydraulic energy, but not the means (21) for storing electrical energy. During travel, the means (21) for storing electrical energy is not recharged by the heat engine (15) which can recharge the means (28, 29) for storing hydraulic energy of the hydraulic motor.
