In this edition of the CRS [Med], a preamble of the format   of the publications is suggested. However, it would be worthwhile to hasten to say that it is likely that there may be considerable alterations in these serial publications with regards to their academics structure, print layout, constituent parts, focus and certainly contents and periodicity. Therefore suggestions and opinions on contents inclusions and modifications are welcome. In principle, publications would normally follow positive peer and editorial reviews, revisions and decisions.
