* Abstract: The purpose, method, results, and conclusion of the research work should be briefly presented in third person. The abstract should not normally exceed 200 words. As the abstract is not part of the text, it should be complete in itself; no table numbers, figure numbers, references or displayed mathematical expressions should be included.

2).Key words and PACS or EEACC numbers

* Key words: Between 3 and 6 key words should be provided. * PACS or EEACC numbers: Between 1 and 3 numbers should be given.
