Review Process
All manuscripts are sent to at least two independent referees who will be asked to complete the refereeing job within 4 to 6 weeks. The final decision regarding acceptance will be made by the Editors. Manuscripts may be sent back to authors for revision if necessary. Revised manuscript submissions should be made as soon as possible (within 4 weeks) after the receipt of the referees’ comments.

Proofs
One set of page proofs in PDF format will be sent by e-mail to the corresponding Author. The author may list the corrections and return to the journal in an e-mail. Please list the corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments on a printout of your proof and return by fax, or scan the pages and e-mail, or by post. This proof should only be used for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will not be considered at this stage. It is important to ensure that all corrections are sent back to the journal in one communication. The publication of the article may be proceeded if no response is received.
Proofs must be corrected and returned to the publishers within 48 hours of receipt.

Offprints: The corresponding author, at no cost, will be provided with a PDF file of the article (e-offprints) via e-mail and 10 free paper offprints.
