Manuscripts received are acknowledged immediately. Authors of papers accepted for publication are entitled to receive thirty reprints at no cost. Additional reprints may be ordered at a charge. A covering letter should contain a statement to that effect.
Copies are available from the editorial office.
Manuscripts reporting only preliminary results are not accepted. Abbreviations should be avoided in the title and abstract. They may be used in the abstract if they are defined when first used by placing them in brackets after the full term. Tables, figures and figure legends should all be presented on separate pages at the end of the article. They should be numbered in arabic numerals.
