The present invention relates to novel formulations for water proofing leather, a process for waterproofing leather, and leather goods waterproofed by the formulations and processes of the present invention. Each XML document is decomposed and encoded as a collection of sub-trees. A first correction amount of the target air-fuel ratio by the first correction value is set to be larger as an injection amount ratio of the intake-port fuel injection valve is larger, and a second correction amount of the target air-fuel ratio by the second correction value is set to be larger as an injection amount ratio of the in-cylinder fuel injection valve is larger. In addition, hybrid parallel decoding schemes may be used in high-level parallelism implementations. An actionable change in the patient is identified. A third embodiment is aluminum tantalum preferably including from 15 to 25 at.
