A computer system includes a symptoms database having symptoms that relate to problems, where each symptom includes an event correlation rule having corresponding predicates. The images may be accompanied by a synchronized audio message. The present invention does not require the isolation of the dabigatran etexilate intermediate. An upper wall of the second oil subchamber is disposed at a level below a full oil surface level of the first oil subchamber. The method and system according to the invention can be implemented by a histogram processing block providing a luminance transfer function followed by a chrominance processing block, where the latter represents a selective chroma adjustment considering each individual pixel of an image.
