Information for contributors Manuscripts

Layout and style Manuscripts should be in English, typewritten, double spaced, on one side of the paper, and the pages numbered. Papers should be fully ready for press, since revision in proof will not be possible. The author is requested to provide three copies of the typescript and figures, and should keep a copy. A short title of not more than 40 characters, for use as page headings, should be supplied and at least 3 key words for indexing papers. A summary must be provided at the beginning of the text. It should not exceed 500 words. Acknowledgements should be placed before the list of references. Tex
