Manuscript preparation

  1. Language

The journal’s language can be English or Portuguese. We request that the language is corrected before submission. Submissions with unsatisfactory English or Portuguese writing will be returned without review. Papers submitted in portuguese must present also an abstract after the “Resumo”.

  1. Length of manuscripts

The journal publishes original papers, short communications (4 pages), technical papers, reviews, letter to the editor (2 pages) and technical notes. In principle, a paper should be no longer than 8 printed pages, but reviews can exceed this number of pages. A detailed description of procedures must be done in the paper or as a supplementary material.

  1. Text Formatting

Manuscripts should be submitted in Word. The submission should include all the figures and tables inserted in the text.

  1. Manuscript structure and instructions

Please follow this order to type the manuscript: title page, abstract, keywords, main text (including tables, figures, and figure captions), acknowledgements, references.

  • Title page.

The title page should contain: (i) concise and informative title; (ii) the name(s) of the author(s); (iii) the affiliation(s); and (iv) the E-mail address(es) of the author(s).

  • Abstract

A concise abstract not exceeding 300 words must be provided. The abstract should state briefly the purpose of the research, the principal results, and major conclusions.

  • Keywords: Please provide 4 to 6 keywords.
  • Heading/Section levels (numbered).

Please divide your manuscript into clearly defined and numbered sections and subsections. Sections should be numbered 1, 2, etc. (The abstract is not included in section numbering). Subsections should be numbered 1.1 (then 1.1.1, 1.1.2 …), 1.2, etc. Each section and subsection should be given a brief heading.

  • Formule and symbols.

Formule, symbols, and all subscripts, superscripts, Greek letters, and other characters must be legible and carefully checked. Standard mathematical notation should be used. All symbols used in manuscript must be explained.

  • Equations

Numbering consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text), and referring the equation with Eq. (1), Eq. (2), …, in the text.

For the simple formulae which appear in the line of normal text, please use solidus (/) instead of a horizontal line for small fractional terms, e.g., x/y. Powers of e are often more conveniently denoted by “exp”. In principle, variables should be presented in italics.

  • Figures

All digital arts, including micrographs, line arts, and grayscale images, included in the manuscript should be supplied in a separate electronic file in TIFF, EPS, or JPEG format with a preferred resolution of 600 dpi relative to the final figure size.

All figures should be numbered using Arab numerals (figure parts should be denoted by lowercase letters) and supplied with a figure caption. Please make sure that all elements found in the figure are identified in the caption.

Figures should always be cited in text, such as Fig. 1, Fig. 2, in consecutive numerical order. Color figures will remain in color in both the printed version and the online version of the journal, at no cost. The authors are encouraged to use color figures in the submitted manuscript.

  • Tables

All tables should be numbered using Arab numerals and supplied with a table title which explains clearly and concisely the components of the table. Tables should not duplicate results presented elsewhere in the manuscript (for example, in figures). Tables should always be cited in the text, such as Table 1, Table 2, in consecutive numerical order.

  • Units

Please use preferably the International system of units (SI).

  • Abbreviations

Abbreviations should be defined at first mention in the text.

  • Acknowledgements

Acknowledgements should be placed in a separate section before the References section.

  • Citation in text.

References to the literature are cited by number in square brackets at appropriate locations in the text. For example: something [10,11]; other thing [1-9].

  • List of references.

All literature citations should be compiled in a numbered reference list at the end of the manuscript text, in the order of their first citation in the text. The list of references should only include works that are cited in the text and that have been published or accepted for publication. Avoid to cite papers accepted for publication.

[6] Information on

  • Electronic Supplementary Material (ESM).

If ESM is submitted, it will be published as received from the author in the online version only. ESM may consist of: (i) information that cannot be printed: animations, video clips, sound recordings; (ii) information that is more convenient in electronic form: sequences, spectral data, etc.; (iii) large amounts of original data, e.g. additional tables, illustrations, etc. If supplying any ESM, the text must make specific mention of the material as a citation, similar to that of figures and tables (e.g., Fig. S1 in the ESM). Besides, a paragraph should be added before the “References” section (e.g., Electronic Supplementary Material: Supplementary material (add a brief description) is available in the online version Link.


4.- After acceptance

The author proof will be send to the corresponding author to check for typesetting errors and the completeness and accuracy of the text, tables, and figures.

Substantial changes in content are not allowed without the approval of the Editor-in-Chief.

After online publication, further changes can only be made in the form of an Erratum, which will be hyperlinked to the article.


The article will be published online after receipt of the corrected proofs. This is the official publication citable with the DOI.
