Author Guidelines

Submission of Manuscripts

Manuscripts can be submitted either electronically at or by regular mail. For authors who prefer paper submission, two copies of the manuscript should be sent to the chief editor. No manuscript submitted should have previously been published or be under consideration for publication elsewhere.


Manuscripts must be typed on one side only. Figures should be drawn directly on the typing paper in the proper position or, alternatively, on separate sheets of sufficient quality for drawing. Authors are encouraged to prepare their manuscripts in LaTeX. Author's affiliation, including e-mail address, should be supplied at the end of the manuscript.


Authors receive only one set of galley proofs. Corrections should be confined to typographical errors and the cost of excessive alterations will be charged to the author.


Authors are offered fifty copies of their papers free of charge. Additional copies can be purchased at authors' cost.
