Authorship : Authors submitting a paper do so on the understanding that the manuscript has been read and approved by all authors and that all authors agree to the submission of the manuscript to the Journal. ALL named authors must have made an active contribution to the paper and ALL must have approved the final version submitted for publication. Participation solely in the acquisition of funding or the collection of data does not justify authorship. It is a requirement that all authors have been accredited as appropriate upon submission of the manuscript. Contributors who do not qualify as authors should be mentioned under Acknowledgements.
Acknowledgements: Under Acknowledgements, please specify contributors to the article other than the authors accredited. Please also include specifications of the source of funding for the study and any potential conflict of interest if appropriate.
Manuscript Authors: At the time of manuscript submission, the definitive list and order of authors should be provided. Any changes including addition, deletion or rearrangement of author names should be made only before the manuscript has been accepted and only if approved by the Editor-in-Chief. To request such a change, the corresponding author should provide: (a) the reason for the change in author list and (b) written confirmation (e-mail) from all authors that they agree with the change(s).
Conflict of Interest: Authors are required to disclose any possible conflict of interest. These include financial (for example patent ownership, stock ownership, consultancies, speaker's fee). Author's conflict of interest (or information specifying the absence of conflict of interest) will be published under a separate heading at the end of your manuscript.
Source of Funding: Authors are required to specify the source of funding for their research when submitting a paper. The information will be disclosed in the published article.
Copyright Assignment: Authors submitting a paper do so on the understanding that the work and its essential substance have not been published before and is not being considered for publication elsewhere. The submission of the manuscript by the authors means that the authors automatically agree to assign exclusive license to Technical University of Gabrovo Publishing if and when the manuscript is accepted for publication. The work shall not be published elsewhere in any language without the written consent of the publisher.
