Headings

The following sequence should be used:

a.Free-standing capitals, bold, at the margin 

b.Free-standing lower-case, bold, at the margin 

If a further subdivision is needed, 1, 2, 3, etc., or (1), (2), (3), etc., or a, b, c, etc., should be used.

References Cited

All references cited to publications made in the text should be presented in a list of references following after the text. The manuscript should be carefully checked to ensure that the spelling of authors’ names and publication dates are exactly the

same in the text as in the reference list.

If reference is made in the text to publications written by more than two authors, the name of the first author should be given, followed by “et al.”. This indication, however, should never be used in the list of references. In this list, names of the first three co-authors followed by “et al.” should be given.

References in the text should be arranged chronologically. The list of references should be arranged alphabetically by authors’ names and chronologically per author.

The following system should be used for arranging references.

Periodical names should be given in full or abbreviated using the International List of Periodical Title Word Abbreviations. In addition, in referring to a personal communication the two words are followed by the year, e.g. “(MeNary, J., personal communication, 1968)”.

Footnotes 

Footnotes should only be used if absolutely essential. If possible the information should be corporated in the normal text. If used, footnotes should be indicated by asterisks and kept as short as possible. If references are given in footnotes, full bibliographic data must be given in the list of references, not in the footnote.

All manuscripts should be governed by above information. Otherwise, publication of articles can be seriously delayed because of corrections.
