Figures incorporated into Word files are also acceptable. Postscript files with line length exceeding 80 characters require encoding. Corrections should be made on proofs using clear conventional signs. The aim of proofreading is to correct errors which might have appeared in the production procedure, not to modify the contents of the paper. Once proofs are corrected, they must be returned to the Editorial Office as soon as possible.
Authors can also renounce their right to proofreading by sending back the proper card.
20 free preprints without cover are granted to authors writing for sections B and C. Authors who renounce proofreading will receive the form as soon as they return the acceptance card.
