To be acceptable a manuscript must make a significant contribution to the advancement of knowledge or toward a better understanding of existing concepts. The study should define principles of broad applicability, be related to problems over a sizeable geographic area, or be of potential interest to a representative number of scientists. Occasionally an editorial may be printed.
Electronic submission is preferred.
Instructions on how to prepare your manuscript for review are provided below. All accepted manuscript files will ultimately be converted to WordPerfect format for on-screen editing. Therefore, we strongly prefer files composed in or converted to WordPerfect. Note that if authors do not use WordPerfect format, many math and Greek characters drop out of text during conversion, which requires extra time and effort in proofreading. The file that is sent for typesetting closely resembles a text-only file.
