Every article submitted will be independently reviewed by several referees. Authors may include the names and addresses of up to 5 experts who could serve as referees. Identification of the referees is optional, at the discretion of the Editor. Decision of acceptance or rejection of a manuscript is the responsibility of the Associate Editors and the Editor, with the Editor assuming final responsibility. This letter must be signed by the author of the article or, in the case of multiple authorship, by at least one of the authors who agrees to take full responsibility and returned to the Editorial Office.
Permission needs to be obtained for the use of borrowed material.
Verbatim quotations totaling more than 200 words, illustrations, tables, and photographs are fully credited as to original author and source. After review and upon acceptance, guidelines for disk submissions will be sent to authors. The original set should contain the original artwork or high-quality glossy prints marked for publication. Manuscripts should be written concisely in English and include only those illustrations or tables that are essential to convey their significance. Authors who are unsure of proper English usage should have their manuscript read by a colleague who is proficient in the English language.
