The present invention relates to novel pharmaceutical compositions based on anticholinergics and NK1-receptor antagonists, processes for preparing them and their use in the treatment of respiratory tract diseases. The wells of both the first and second PMOS well transistors are coupled to the voltage output node to provide reverse isolation. At least one actuator on the rotor blade to actuate a device on the rotor blade, where the at least one actuator is connected to the high pressure volume to receive air from the high pressure volume for actuation. Also, a digital-to-analog converter using said weight generators is equipped with a digital signal source, a weight controller, and a weight generator. The coil is powered by an alternating current for providing an alternating dynamic magnetic flux following the first path through a magnetic circuit. The cooler effectiveness is mathematically modeled as a function of various temperatures and over an operation history that includes one or more engine shut-downs.
