The summary should include references to the relating pages respectively tables or figures which contain the supporting material for the results attained.
All manuscripts are subject to peer review.
In order to reduce the considerable costs of postage, word-processor generated manuscripts will not be returned except at the explicit request of the author. The data file should correspond completely to the submitted printout of the manuscript. Originals of illustrations must only be submitted at the editors request. Illustrations should not be sent as data files. Neither formal alterations nor other changes in the proofs shall be included.
