In accordance with COPE's Core Practices, Delta: Journal of Physics (DJOP) clearly defines its intellectual property policies, ensuring transparency and adherence to ethical publishing standards.

Copyright and Publishing Licenses:

DJOP operates under a Creative Commons Attribution-NonCommercial 4.0 International License, which allows non-commercial use of the articles with proper attribution. Authors retain substantial rights, including copyright and the right to disseminate the article for non-commercial purposes.

Publication Costs:

As an open-access journal, DJOP does not charge any fees for article submission, processing, or publication. All articles are freely available to both authors and readers.

Prepublication:

Work that has been previously published in a substantial form will not be considered for publication in DJOP. A substantial form may include publication in other journals, books, or online platforms that are publicly accessible.

Plagiarism and Redundant Publication:

DJOP defines plagiarism as the appropriation of another author's language, thoughts, ideas, or expressions without proper acknowledgment and considers redundant or overlapping publication as the concurrent submission of the same manuscript to multiple journals. Both are strictly prohibited and subject to severe editorial action.

This policy serves to protect and respect intellectual property rights and to clarify the responsibilities of authors, ensuring the integrity of the scholarly record.
