How to submit

Authors have to submit their manuscripts online Electronic submission substantially reduces the editorial processing and reviewing times and shortens overall publication times. Please follow the step and fill the data for submit online and upload all of your manuscript files following the instructions given on the screen.


Authors wishing to include figures, tables, or text passages that have already been published elsewhere are required to obtain permission from the copyright owner(s) for both the print and online format and to include evidence that such permission has been granted when submitting their papers. Any material received without such evidence will be assumed to originate from the authors.


Manuscript structure

Manuscripts submitted must be in British or American English. Authors whose native language is not English should have their work reviewed by a person well-versed in the English language before submitting the manuscript. It is not the Editors’ or Referees’ responsibility to provide language assistance, and poorly-written manuscripts may be grounds for rejection.

The preferred format for manuscripts is Microsoft® Word (.doc and not .docx). For submission in other formats produced with other word processing applications, authors should email the Managing Editor regarding document compatibility before sending the manuscript.

The manuscript should be arranged into the following sections:

  • Introduction
  • Material and Methods
  • Results and Discussion
  • Conclusion
  • Acknowledgements
  • Reference


The title should be clear, concise and informative sentence, accurate, unambiguous, specific, and completely identify the main issue of the paper, preferably not more than 30 words (i.e. 3 lines max), It should be typed in sentence case and in bold. If there are Latin names of plants and animals, please do not mention the name of the author in the title. (This authority needs to appear only once in the article, with the first mention of the taxon in the text). Avoid abbreviations and formulae where possible.

Authors name and affiliations

Author names should not contain academic title, official rank, or professional position. Please clearly indicate the given name(s) and last/family name(s) -full name if possible- of each author and check that all names are accurately spelled. Present the authors' affiliation addresses (where the actual work was done) below the names. Write clear affiliation of all Authors. Affiliation includes: name of department/unit, (faculty), name of university/institution, complete postal address, and country. All contributing author should be shown in contribution order.


A concise and factual abstract is required and must be written in English (maximum length of 300 words). The abstract should state briefly the purpose of the research, the methods used, the principal results and major conclusions. Please try to keep each sentence as specific as possible, and avoid such general statements as "The management implications of the results are discussed". An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, they must be cited in full, without reference to the reference list. Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself


Up to five keywords should be supplied, and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.


Introduction is about 200-600 words. State the objectives of the work and provide an adequate background, state of the art, and should be avoiding a detailed literature survey or a summary of the results. Explain how you addressed the problem and clearly state the aims of your study.

Materials and Methods

Materials and Methods should emphasize on the procedures and data analysis. Should be clearly and concisely stated. Provide sufficient details to allow the work to be reproduced by an independent researcher. Methods that are already published should be summarized and indicated by a reference. If quoting directly from a previously published method, use quotation marks and also cite the source. Any modifications to existing methods should also be described.

A Theory section (if necessarily added) should extend, not repeat, the background to the article already dealt with in the Introduction and lays the foundation for further work. A Calculation section represents a practical development from a theoretical basis.

Results and Discussion

Results should be clear and concise. Discussion should explore the significance of the results of the work, not repeat them. Avoid extensive citations and discussion of published literature.

The following components should be covered in the discussion section: How do your results relate to the original question or objectives outlined in the Introduction section (what)? Do you provide interpretation scientifically for each of your results or findings presented (why)? Are your results consistent with what other investigators have reported (what else)? Or are there any differences?


The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section. The conclusion section should lead the reader to the important matter of the paper. Suggestion or recommendation related to further research can also be added but not to confuse the research with an uncompleted work.


Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.), grants and funds. The names of funding organizations should be written in full.


It is not recommended to use appendices in Natural Science: Journal of Science and Technology submission.


The list of References should be included after the final section of the main article body. A blank line should be inserted between single-spaced entries in the list. Authors are requested to include DOIs and/or links to online sources of articles, whenever possible!

References should be arranged first alphabetically and then further sorted chronologically if necessary. More than one reference from the same author(s) in the same year must be identified by the letters 'a', 'b', 'c', etc., placed after the year of publication. Unpublished data or personal communication should not appear in the list but should be cited in the text as ‘unpubl. data’.

Reference list entries should be alphabetized by the last name of the first author of each work.

Citation in text

Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'. Citation of a reference as 'in press' implies that the item has been accepted for publication.

 Web references

As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

References in a special issue

Please ensure that the words 'this issue' are added to any references in the list (and any citations in the text) to other articles in the same Special Issue.

Journal abbreviations source

Journal names should be abbreviated according to Index Medicus journal abbreviations:; List of title word abbreviations:; CAS (Chemical Abstracts Service):



The acronyms and scientific abbreviations should be defined at first mention in the text, except
for the common ones (DNA, RFLP, PCR, ANOVA, etc.). The authors’ initials and the abbreviated titles of the journals should be presented with punctuation marks in the list of references.

Units should be from the International System of Units (SI) (English version available at:
For example, hectares and ppm do not belong to the SI and should be changed into m2 and mg/kg or μL/L, respectively.
On the SI website you also find the official abbreviation of each unit. For example: 1 h = 60 min = 3600 s and 1 d = 24 h
The official abbreviation of liter is L. We use L to discriminate from 1 (one). Time is expressed as follows: 1150 h for 11h50 a.m. and 1715 h for 5h15 p.m.

Latin names

The Latin names as well as the authority must be cited in full at the first mention in the text and then the genus abbreviated in the following citations. The authority should not appear in the title or the abstract. Latin genus and species must be italicized.
Geographical coordinates

When the location of the experiment is meaningful, geographic coordinates of the place should

be added.




  • All tables are to be numbered using Arabic numerals.
