Figures and tables should follow the references. Make sure that every table or figure is referred to in the text. The table or figure will be placed after the first mention in the text. Legends should be short, descriptive and define any acronyms, abbreviations or symbols used.


Authors are responsible for supplying camera-ready copy of their figures. Number figures with Arabic numerals in order of appearance. The font used for labelling should be no smaller than 8 points after the figure has been resized to one text column width during typesetting. Tints are not acceptable as they do not reproduce well in printing.


Number each table consecutively with Arabic numerals and double space them on separate pages. Avoid using vertical rules. Horizontal rules should be used only above and below column headings and at the bottom of the table.
