An engine and an engine control strategy for lean-to-rich transitions, such transitions being useful for various purposes, one of which is purging, or regenerating, a NOx adsorber in the engine exhaust system. The present invention also relates to a process for applying discrete portions of a web material onto a receiving web using the above described apparatus. The recording sheet with an ink-receptive layer includes a substrate sheet and an ink-receptive layer formed thereon, wherein the ink-receptive layer includes fibrous crystalline particles on surfaces of which a cationic hydrated metal compound is supported and a binder. The compositions can be used to treat various diseases, such as wound healing, inflammation and angiogenesis-related diseases. The coupling agents are advantageously used in rubber formulations, including tire compositions, for example, for fabricating tires with low rolling resistance.
