Article Processing Fee

There is no fee for manuscript submission to this journal. However, if the manuscript is accepted for publication, the author(s) will be asked to pay an Article Processing Fee (USD 250) to cover publications costs. Because the journal editors do not want rigorous work to be prevented from publication, in case of lack of funds to pay such fees, the requested fees could be waived. The submission cannot be withdrawn by the author after the manuscript is accepted for publication. Payment might be made via Western Union, wire transfer, or  online payment system via credit card.
