This invention relates to compounds of Formula I and the use of compounds of Formula I as neuroprotective agents in the treatment of neuronal disorders of the central and peripheral nervous systems. Pressure air from the truck tractor brake system is conducted through a valve to an actuator for effecting movement of a coupler member to release engagement with a corresponding coupler fitting mounted on a trailer. At least one spring contact is connected to the printed circuit board and extends into the cavity. A definition file associated with definition file location attribute is retrieved. The channels allow passage of air around the valve member with less restriction when the valve member is lifted off the valve seat. The food composition is substantially free of carbohydrates or free of carbohydrates, and has excellent taste and rheological properties.
