Proofs and reprints

Proofs will be sent to the corresponding author. They should be carefully corrected and returned to the publisher within 72 h of reception. If this period is exceeded, the galleys will be proofed only by the editorial staff of the publishing house and printed without the author’s corrections. The proof stage is not the time to make extensive corrections, additions or deletions. The cost of changes introduced by the author that are deemed to be excessive will be charged to the author.
Ten reprints and a pdf. file of the article are available free of charge. An order form for additional reprints – and, if required, for the publication of color figures – will accompany the proofs.
