Author Guidelines


The journal Semina: Exact and Technological Sciences is a biannual publication promoting Science and Technology and is associated with the State University of Londrina. The journal publishes original and review articles in all areas of Technology, including: Physics, Chemistry, Mathematics, Statistics, Geosciences, Computation, Engineerings and Architecture Sciences.

Articles suitable for publication in the journal are those written in english. All papers must be proofread and spell checked before submission. The Editors may request language revision at any moment during the review process. When requested, the authors must present a certificate of revision emitted by a specialized company/ professional, attesting formal review of English language and grammar

The manuscript must be submitted in electronic form. The work must be edited in Microsoft Word or LaTex, PREFERENTIALLY in LATEX. 

Publications may be in the form of original and review articles:

  • Original Articles must include the sections: Introduction, Methods, Results, Discussion, Conclusions and References. Figures, tables, diagrams, etc., must be in the text. Original articles must have a maximum of 15 (fifteen) pages.
  • Review Articles should communicate progress in a specific field, with the objective of providing a critical account of the state-of-the-art from the point of view of the highly qualified and experienced specialist. Review Articles must include the sections: Introduction, Methods, Results, Discussion, Conclusions and References. Figures, tables, diagrams, etc., must be in the text. Original articles must have a maximum of 20 (twenty) pages.

Authors should present their material with utmost conciseness and clarity. The Introduction section should clearly and briefly identify, with relevant references, both the nature of the problem under investigation and its background. An Introduction consisting of an extensive literature review is not acceptable.

The Experimental section may precede or follow the Results and Discussion section but must be separate. The Conclusions section, which briefly summarizes the main conclusions of the work, must be presented immediately after the Results and Discussion section.

Experiments should be described in sufficient detail to enable other researchers to repeat them. The degree of purity of materials and their quantities should be reported. Descriptions of established procedures are unnecessary. An apparatus should be described only if it is non-standard. Commercially available instruments should be referred to by their suppliers and models. 

Many theoretical and computational papers use a routine procedure based on a well-documented method, be it semi-empirical or ab initio. In such cases, it is sufficient to name the particular variant (referring to key papers in which the method has been developed), to cite the computer program used, and to indicate briefly any modifications made by the author. 

It is the authors' responsibility to obtain permission from the copyright holder for the reproduction of figures from other publications. The obtained Copyright Permission should be sent along with other files when submitting the manuscript. Suitable acknowledgement of reproduction must be provided in the captions.

The editors of Semina journal reserve the right to make minor changes to the manuscript, if necessary, so that the paper conforms to the norms of the journal or to improve the style without modifying the content of the article. Whatever the nature of the manuscript, it should be original in terms of methodology, information, interpretation, and critique. The quality of the article can be attested by two referees selected by the editors. 



The submission of a manuscript implies that it has not been previously published, that it is not under consideration for publication elsewhere, and that it will not be simultaneously published elsewhere in the same format without the written permission of the Editors, otherwise, it must be justified in the COMMENTS FOR THE EDITOR field. Additionally, it implies that the submitting author has the consent of all authors. By submitting a manuscript, the authors agree that their paper's copyright is transferred to the journal Semina: Exact and Technological Sciences if and when the manuscript is accepted for publication. Accepted manuscripts and illustrations become the property of the journal.



Style guide: The journal Semina uses the ABNT standards for the articles.

Use a TrueType font (Times New Roman preferred, 12pt) and normal face. It is important that you allow generous margins (minimum 2cm) and set your manuscript in doble-column format with double-line spacing.

Acronyms and abbreviations should be clearly defined on their first occurrence in the text by writing the term out in full and following it with the abbreviation in parentheses, e.g. code division multiple access (CDMA). Common abbreviations, e.g. CMOS, need not be defined. If in doubt, please define the abbreviation.

The journal Semina not publish footnotes. Any author notes must be included in the reference list and its in-text citations must follow the same numerical order for reference citations.

Title: Titles should be concise (not more than 20 words), informative, and should not include a subtitle.

Author affiliations: These should immediately follow the title. For one or multiple-authored articles list the names of all the authors first, followed by the full postal and email addresses. These must be included as footnotes using identifiers to link an author with an address. Very short biographies and author’s technical interests may be informed as well.

Abstract: The Abstract should be informative and not only indicate the general scope of the article but also state the main results obtained, methods used, the value of the work and the conclusions drawn. No table numbers, figure numbers, references or displayed mathematical expressions should be included. It should not exceed 200 words. Following the abstract list the key-words intended for fast referencing of the submitted paper.

Figures and figure captions: Figures can be included in the text and should be accompanied with figure captions following the same order as figures appear in the text. Moreover, each figure should be explicitly referred to in the text in numerical order, e.g., Figure 1, Figure 2 (a), Figure 2 (b) and so on. As the SEMINA paper-based version is black and white printed, colour should not be used for distinguishing data in line diagrams; instead use lettering, numbering or different types of line (full, dashed, dotted) or data point (square, triangle, cross). Note that light colours do not reproduce well when printed in black and white and could therefore make your data indistinguishable. Figure legends should preferably appear boxed in the figure itself but may also be described in the caption. Figure captions should be kept as concise as possible. An additional .zip or .tar archive for uploading containing all illustrations (pictures, graphs, tables) in high definition .TIFF format (minimum 300 d.p.i) is also required for final paper edition. The individual files should be named in order as they appear in the text, i.e, Fig_1.tif, Fig_2.tif and so on. In case of copyrighted material the authors should obtain, from the owners of the copyright, written permission to reproduce any illustration for which the copyright is not their own. The source of the illustration must be given in full and the words “Reproduced by permission of .. “ included with the illustration.

Tables: Tables can be included in the text and should be accompanied with headings explaining the presented data. Each table should be referred to explicitly in the text in numerical order. Avoid the use of unusual mathematical characters or graphical material in tables. In such a case, set the table as a figure instead.

Algorithms: Algorithms should not be boxed and should be set as normal text or figures.

Mathematics and equations: When writing mathematics, be sure to avoid confusion between characters that could be mistaken for one another, e.g. the letter "l" and the number 1. If your paper contains superscripts or subscripts to superscripts or subscripts, take special care to ensure that the positioning of the characters is unambiguous. Ensure that superscripts and subscripts are used consistently in the body text, figures and tables. Exponential expressions should be written using superscript notation, i.e. 5x103 not 5E03. A multiplication sign (x) should be used, not a dot (.). Symbols representing vectors and matrices should be in bold font. Refer to equations using round brackets, e.g. (1).

System of units: The journal Semina adopts the International System of Units-SI for physical parameters and units.

Submission conditions: As part of the submission process, authors are asked to verify their submission's compliance with all the following items. The submissions may be returned to authors who do not comply with these guidelines.
