A game is provided based on real data which changes with time reflecting phenomena occurring in real life. For synthesis mixtures with a sufficiently high XO2:Y2O3 ratio, seeding a synthesis mixture with ZSM-5 seed crystals can result in production of pure phase ZSM-5 crystals with a new morphology. In addition, other methods for providing LAG to heterogeneous switches are also described, along with systems and computer program products which provide LAG to heterogeneous switches. The fan control switch is mounted on a mounting plate that is welded to the combustion chamber to provide a planar contact surface for the switch mechanism.
