Ethics in publishing

Declaration of competing interest

Corresponding authors, on behalf of all the authors of a submission, must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. A submitted manuscript must be accompanied by a form of "Conflict of interest statement" for authors. Corresponding authors should attach a statement to declare any potential conflicts of interest. Also, a conflict-of-interest statement is mentioned in the published articles.

Submission declaration and verification

Submission of an article implies that the work described has not been published previously (except in the form of an abstract, a published lecture or academic thesis, that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or any other language, including electronically without the written consent of the copyright holder.

Changes to authorship

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion, or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in the author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal, or rearrangement. In the case of adding or removing authors, this includes confirmation from the author being added or removed.

Only in exceptional circumstances will the Editor consider the authors' addition, deletion, or rearrangement after the manuscript has been accepted. While the Editor considers the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editor will result in a corrigendum. 

Copyright

Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement.' An e-mail will be sent to the corresponding author confirming receipt of the manuscript, a 'Journal Publishing Agreement' form, or a link to the online version of this agreement. 

NEW SUBMISSIONS
Submission to this journal proceeds online, and you will be guided step-by-step through creating and uploading your files.

As part of Your Paper, you must submit your manuscript as a single PDF file or Word document without a title page to be used in the refereeing process.

 It should contain high-quality figures for refereeing. Individual figure files larger than 10 MB must be uploaded separately.

Article structure

The manuscript should be compiled in the following order:

1. Title page
2. Abstract, Keywords
3. Introduction
4. Material and methods
5. Results and Discussion
6. Conclusion
7. Acknowledgment(s)
8. Conflict of Interest
9. References

1- Essential title page information

• Title. Concise and informative. Titles are often used in information retrieval systems. Avoid abbreviations and formulae where possible.
• Author names and affiliations. Please clearly indicate each author's given name(s) and family name(s) and check that all names are accurately spelled. Below are the names, present the authors' affiliation addresses (where the work was done). Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
• Corresponding author. Indicate who will handle correspondence at all stages of refereeing publication and post-publication. This responsibility includes answering any future queries about Methodology and Materials. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author.

2- Abstract

Please provide a structured abstract of 150 to 300 words, which should be divided into the following sections:

• Purpose (stating the primary purposes and research question)
• Methods
• Results
• Conclusion

Keywords

• Please provide 4 to 6 keywords which can be used for indexing purposes.

3- Introduction

The authors should clearly define the significance of their work and justify its publication. Background discussion should be concise and focused on relevant information.

4- Material and Methods

Authors should strive to describe the experimental procedures concisely. The methods section must include all necessary information to ensure reproducibility. Previously published methods should be referenced, with only relevant modifications described. Please provide vendor details for chemicals, reagents, strains, etc., including company, city, and country. Statistical analysis should include the appropriate test(s) and the hypothesized p-value or significance level (e.g., 0.05).

5- Results and Discussion

The study results should be presented clearly and concisely. Use tables and figures sparingly, including only data essential to the study's message and interpretation. Avoid duplicating data in both figures and tables. Present the results logically within the text, tables, and illustrations. 

The discussion should focus on the significance of the study results rather than repeating them. It should explore the implications of the findings, their limitations, and how they relate to other relevant work. It should also provide directions for future research. 

6- Conclusion(s)

Present the main conclusions of the study in a concise conclusion statement that can stand alone and align with the study's goals. Introduce new hypotheses when appropriate and include recommendations when relevant. Avoid making unqualified statements or drawing conclusions not fully supported by the obtained data.

7- Acknowledgements:

Collate acknowledgments in a separate section at the end of the article before the references. Acknowledgments of people, grants, funds, etc., should be written. The names of funding organizations should be written in full.

8- Conflict of interest

They should state there is no conflict of interest. It should be stated clearly before Acknowledgements

9- References

References should be indicated in the text by consecutive numbers in square brackets, e.g. [1], [2,3], [4-6], as part of the text, not raised above it. The complete reference is cited in a numbered list at the end of the text. Ensure you are using ABNT Citation Styles. Other standard citation methods are also acceptable.

Further considerations

Text Formatting

Manuscripts should be submitted in Word.

• Use a standard, plain font (e.g., 12-point Times Roman) for text.
• Use italics for emphasis.
• Use the automatic page numbering function to number the pages.
• Do not use field functions.
• Use the table function, not spreadsheets, to make tables.
• Use the equation editor or Math Type for equations.
• Save your file in docx format (Word 2007 or higher) or doc format (older Word versions).

Abbreviations

Abbreviations should be defined at the beginning of the mention and used consistently after that.

Units and abbreviations

Please adhere to internationally agreed standards such as those adopted by the International Union of Pure and Applied Physics (IUPAP) Commission or defined by the International Organization of Standardization (ISO). Metric SI units should be used throughout except where non-SI units are more common [e.g., liter (l) for volume].

Abbreviations (not standardized) should be defined at first mention in the abstract and again in the main body of the text and used consistently after that.

Tables

• All tables are to be numbered using Arabic numerals.
• Tables should always be cited in the text in consecutive numerical order.
• For each table, please supply a table caption (title) explaining the components of the table.
• Identify any previously published material by referencing the source at the end of the table caption.

Footnotes to tables should be indicated by superscript lower-case letters (or asterisks for significance values and other statistical data) and included beneath the table body.

Figure Submission

• Supply all figures electronically.
• The preferred format for vector graphics is EPS; for halftones, please use TIFF format. MS Office files are also acceptable.
• Vector graphics containing fonts must have the fonts embedded in the files.
• Name your figure files with "Fig" and the figure number, e.g., Fig1.eps.

Line Art

• Definition: Black and white graphic with no shading.
• Do not use faint lines and/or lettering; check that all lines and lettering within the figures are legible at the final size.
• All lines should be at least 0.1 mm (0.3 pt) wide.
• Scanned lines and line drawings in bitmap format should have a minimum resolution of 1200 dpi.
• Vector graphics containing fonts must have the fonts embedded in the files.
• Definition: Photographs, drawings, or paintings with fine shading, etc.
• If any magnification is used in the photographs, indicate this using scale bars within the figures themselves.
• Halftones should have a minimum resolution of 300 dpi.
• Definition: a combination of halftone and line art, e.g., halftones containing line drawings, extensive lettering, color diagrams, etc.
• Combination artwork should have a minimum resolution of 600 dpi.

Figure Lettering

• To add lettering, it is best to use Helvetica or Arial (sans serif fonts).
• Keep lettering consistently sized throughout your final-sized artwork, usually about 2–3 mm (8–12 pt).
• The variation of type size within an illustration should be minimal, e.g., do not use 8-pt type on an axis and 20-pt type for the axis label.
• Avoid effects such as shading, outline letters, etc.
• Do not include titles or captions within your illustrations.

Figure Numbering

• All figures are to be numbered using Arabic numerals.
• Figures should always be cited in the text in consecutive numerical order.
• Figure parts should be denoted by lowercase letters (a, b, c, etc.).
• If an appendix in your article contains one or more figures, continue the consecutive numbering of the main text. Do not number the appendix figures, "A1, A2, A3, etc." However, figures in online appendices [Supplementary Information (SI)] should be numbered separately.

Figure Captions

• Each figure should have a concise caption describing accurately what it depicts. The captions should be included in the manuscript's text file, not the figure file.
• Figure captions begin with the term Fig. in bold type, followed by the figure number in bold type.
• No punctuation will be included after the number, nor will any punctuation be placed at the end of the caption.
• Identify all elements found in the figure in the figure caption, and use boxes, circles, etc., as coordinate points in graphs.
• Identify previously published material by giving the source as a reference citation at the end of the figure caption.

Payment and Cost of Publication

The article processing charge (APC) will be waived for content submitted to this journal before 31 December 2025.
