Abstract

An abstract not exceeding 200 words should be informative rather than indicative and given on a separate page. All relevant key words should be included in the abstract.

Number all hierarchical headings decimally (e.g., 1. First level heading, 1.1. Second level heading, 1.1.1. Third level heading).

Tables

Tables should be comprehensible without reference to the text. Avoid long column headings, complicated structure and vertical lines. Plan your tables for column or page width, 40 and 80 letter spaces, respectively.

Illustrations

Illustrations should be numbered consecutively as Figures or Maps. Line drawings should be made clearly in deep-black ink and submitted as original drawings or photographic prints. Photographs (b/w or color) should be submitted as sharp, high contrast prints trimmed at right angles. Half tone drawings must be the originals. If dimensions are important a measuring line should be given on the photograph. Parts within composite illustrations should be identified with letters, not numbers. Plan your figures for column (79 mm width) or page (164 × 215 mm) size when printed, but reserve space for the legend.

References

References should be listed in alphabetical order under the first author's name and should refer only to publications cited in the text. The following are examples of the format to be used for articles from journals, books, and non-serial collective publications, respectively.
