The interest in studying the isochrone portrait of relaxation oscillators with a stable limit cycle is that knowledge of this portrait implies knowledge of the Phase Transition Curve (PTC) and the PTC allows one to obtain, in the case of impulsive forces, a one-dimensional approximation of the...

This paper describes a refrigeration system using a natural refrigerant that has been developed to reduce significantly both direct and indirect greenhouse gas emissions. The new system uses both R-404A and CO₂ (R-744) as refrigerants. The new system has very low global warming potential...
