Qubahan Engineering Journal (QENGJ) welcomes original, scientifically rigorous, and ethically conducted manuscripts that fall within the journal's Aims and Scope.

Article Types

QENGJ considers:

• Original Research Articles

• Review Articles

• Systematic Reviews

• Technical Articles

• Case Studies

• Short Communications

• Methodological Articles

• Perspectives

• Interdisciplinary scholarly contributions

Originality

Submitted manuscripts must represent original work that has not been published previously and is not simultaneously under consideration by another journal.

Plagiarism, duplicate publication, redundant publication, fabrication, falsification, inappropriate image manipulation, citation manipulation, peer-review manipulation, and other forms of research misconduct are prohibited.

Authors must disclose relevant previous publications, conference versions, preprints, datasets, or closely related manuscripts where appropriate.

Language

Manuscripts must be written in clear, professional English.

Authors are responsible for ensuring that the language is sufficiently clear for scientific and scholarly evaluation.

Manuscript Structure

Original research manuscripts should normally include:

• Title

• Author names

• Institutional affiliations

• Corresponding author information

• Abstract

• Keywords

• Introduction

• Materials and Methods / Methodology

• Results

• Discussion

• Conclusion

• Data Availability Statement, where applicable

• Author Contributions

• Funding Statement

• Conflict of Interest Statement

• Ethics Statement, where applicable

• Generative AI Declaration, where applicable

• Acknowledgments, where applicable

• References

The structure may be adapted where appropriate for review articles, architecture studies, technical papers, methodological studies, and other article types.

Title

The title should be concise, informative, specific, and accurately reflect the principal content of the manuscript.

Titles should avoid unnecessary abbreviations, exaggerated claims, and misleading terminology.

Abstract

The abstract should provide a concise and accurate summary of the study.

For original research, it should normally communicate:

• Research background or problem;

• Objective;

• Methodology;

• Principal findings; and

• Main conclusion.

The abstract should not contain unsupported claims or information that does not appear in the manuscript.

Keywords

Authors should provide appropriate keywords that accurately represent the manuscript's main subject areas and support indexing and discoverability.

Tables and Figures

All tables and figures must:

• Be numbered consecutively;

• Be cited in the manuscript;

• Include informative captions;

• Be legible and of appropriate publication quality;

• Accurately represent the underlying research findings; and

• Identify the source and permission status of third-party material where applicable.

Images must not be manipulated in a manner that misrepresents research findings.

Equations and Technical Information

Equations, mathematical expressions, symbols, variables, abbreviations, engineering parameters, and technical terminology should be presented consistently and clearly defined.

International System of Units (SI) should be used wherever appropriate.

References

References must be accurate, complete, relevant, and based on sources actually consulted by the authors.

Authors are responsible for verifying references before submission.

The following practices are unacceptable:

• Fabricated references;

• Irrelevant citations;

• Citation manipulation;

• Excessive self-citation intended to influence metrics; or

• Citation of sources that authors have not reasonably verified.

Authorship

Authorship should be limited to individuals who have made substantial scholarly contributions to the work and who accept responsibility for the published article.

All listed authors must:

• Approve the submitted manuscript;

• Approve the final version;

• Agree to the authorship order;

• Accept accountability for their contributions; and

• Disclose relevant competing interests.

Guest, honorary, purchased, fraudulent, and ghost authorship are prohibited.

Author Contributions

Authors should provide a clear statement describing individual contributions.

Use of the CRediT Contributor Roles Taxonomy is encouraged where appropriate.

Conflicts of Interest

All authors must disclose financial, professional, institutional, personal, or other interests that could reasonably be perceived as influencing the research or its interpretation.

Where no competing interests exist, authors should state this clearly.

Funding

All sources of financial support must be disclosed.

Grant numbers and funding organizations should be identified where applicable.

The role of the funding body should be disclosed where it influenced study design, data collection, analysis, interpretation, or publication.

Research Ethics

Research involving human participants, animals, personal or sensitive data, or activities requiring formal ethical oversight must comply with applicable institutional, national, and international ethical requirements.

Where applicable, manuscripts must state:

• Name of the approving ethics committee or institutional review board;

• Ethics approval/reference number;

• Approval date where available;

• Informed consent information;

• Parent or guardian consent and participant assent where applicable;

• Consent for publication of identifiable material; and

• Other relevant ethical or regulatory approvals.

Where formal ethical approval was not required, an appropriate explanation should be provided when relevant.

Data Availability

Authors should provide a Data Availability Statement where appropriate.

Data, software, code, computational parameters, experimental records, or other supporting materials should be made available where ethically, legally, and practically possible.

Restrictions involving privacy, confidentiality, intellectual property, security, or commercial sensitivity should be explained.

Generative Artificial Intelligence

Generative AI systems cannot qualify as authors.

Authors remain fully responsible for:

• Accuracy;

• Originality;

• References;

• Data integrity;

• Interpretation;

• Ethical compliance; and

• All submitted content.

Material use of generative AI in manuscript preparation must be disclosed in accordance with the QENGJ Generative Artificial Intelligence Policy.

Copyright and Permissions

Upon acceptance and publication, copyright is transferred to Qubahan Engineering Journal in accordance with the journal's Copyright Policy.

Authors are responsible for obtaining permission to reproduce copyrighted material belonging to third parties.

Editorial Authority

Submission does not guarantee publication.

The Editor-in-Chief or authorized handling editor may reject manuscripts that:

• Fall outside the journal's scope;

• Lack sufficient originality;

• Have serious methodological weaknesses;

• Fail to meet ethical requirements;

• Present significant research-integrity concerns;

• Are inadequately prepared; or

• Are otherwise unsuitable for external peer review.

The final publication decision remains the responsibility of the journal.
