The invention describes a compound having the formula, wherein X is F, Cl, Br, or I; R1 is CH3, C2H5, C2H4R3, C2H3R3R4, C3H7, C3H6R or C3H5R3R4; R is H, CH3, C2H5, C2H4R3 or C2H3R3R4; and R3 and R4 are, independently, X, OH or NH2 for the treatment of plants, for increasing plant growth. The signalingcontrol data may include an alert of an incoming mobile terminated session that is transmitted to the user equipment based on the type of user equipment and the level of integration. The cooling system calculates a cooling loss as a quantity of heat removed from the engine by the coolant, based on an operating state of the engine, and calculates a required radiator flow rate, based on the cooling loss, the target coolant temperature, and a temperature of the coolant that has passed through the radiator.
