To cover all costs we apply a fee of USD for each accepted paper including shipment for one original hard copy to the corresponding author. For extra copies please contact the editor. Each extra copy will be charged $ 20.
You can pay the fee through Paypal, Credit Card or Bank Transfer. If in your country these methods are impossible we can accept Western Union or Money Gram. Please contact the editor for the payment through Western Union or Money Gram.
Publication fee Special Editions
The publication fee for special editions will be discussed with institutions based on their requests.
In case of double payment we will refund the fee by Bank Transfer. In this case bank charges will be paid by both, journal and author. If you have paid through Paypal or if you have a Paypal account we will refund the money in your Paypal account to avoid the bank charges. In case of acceptance of the paper and when your paper is scheduled for publication or it is just published no refund will be applied if authors withdraw the paper.
You can pay the publication fee by PayPal, Westren Union, Credit Card or Bank Transfer. Please do not hesitate to contact us, if you are having any difficulties regarding payment.
