Four paper copies and an IBM-compatible disk copy should be supplied in the first instance. Authors are advised to retain a copy themselves as protection against loss in the post. Manuscripts may be of any length consistent with their content. A list of 4-6 key words should be provided directly below the abstract. Key words should express the precise content of the manuscript, as they are used for indexing purposes.
Submitted manuscripts are subject to a blind-review process.
Therefore, omit the author's name from all manuscript pages, including the title page. A brief biographical note, included on a separate manuscript page at the end of the paper, should describe the authors' qualifications, experience, and current interests. Authors must provide high-quality artwork for all figures. Poor-definition reproductions are not suitable. Each table and figure should be given a title and should be presented on a separate manuscript page at the end of the paper.
