Author Guidelines

The Journal of Natural Sciences seeks contributions on theoretical, basic, empirical and applied research in all the areas of Chemistry, Physics, Bilogy, Mathematics, Statistics. 


Manuscripts should be submitted by one of the authors of the manuscript through the online Open Journal Systems. Regardless of the source of the word-processing tool, only electronic PDF (.pdf) or Word (.doc, .docx) files can be through the OJS. There is a maximun of 6 pages limit. Submissions by anyone other than one of the authors will not be accepted. The submitting author takes responsibility for the paper during submission and peer review.


Title and Authorship Information

The following information should be included

  • Paper title
  • Full author names
  • Full institutional mailing addresses
  • Email addresses



The manuscript should contain an abstract. The abstract should be self-contained and citation-free and should not exceed 200 words. All articles shall include an abstract, both in Spanish and in English. 



This section should be succinct, with no subheadings.


Materials and Methods

This part should contain sufficient detail so that all procedures can be repeated. It can be divided into subsections if several methods are described.


Results and Discussion

This section may each be divided by subheadings or may be combined.



This should clearly explain the main conclusions of the work highlighting its importance and relevance.



All acknowledgments (if any) should be included at the very end of the paper before the references and may include supporting grants, presentations, and so forth.



Authors are responsible for ensuring that the information in each reference is complete and accurate. Articles should be fully documented with references in the text and a reference listing ordered alphabetically by author’s names at the end of the paper. Digital object identifiers (DOIs) should be provided whenever possible for each reference. Authors are encouraged to adjust to the citation system. Examples:

Articles in journals:

Hoerling M. P. and Kumar A., 2002. Atmosphere response patterns associated with tropical forcing. J. Climate 15, 2184-2203.

Chapters in books:

Magaña V. and Conde C., 2003. Climate variability and climate change and their impacts on the freshwater resources in the border region: A case study for Sonora, México. In: Climate and water-transboundary challenges in the Americas (Díaz H. F. and Morehouse B. S., Eds.). Kluwer Academic Publishers, Dordrecht, 373-393.

Articles in proceedings:

Gallardo L., Córdova A. M., Rojas M., Quintana J., Alcafuz R. and Ramos I., 2004. Stratosphere-troposphere exchange (STE) over Easter Island and Cerro Tololo stations in South America: analysis and simulation of an intensive sounding campaign. 8th International Global Atmospheric Chemistry Conference, Christchurch, New Zealand, September 2004.


Thompson R. D., 1998. Atmospheric processes and systems. Routledge, New York, 194 pp.

References cited in the text should indicate, within parenthesis, the last name of each author and the year of publication. If there are more than two authors, the last name of the first author should be followed by et al. When the name forms part of the content of the article, and does not appear solely as a reference, the year of publication is parenthesized. For example:

...a weekly cycle has been observed in surface temperature (Gordon, 1994).

...Gordon (1994) has observed a weekly cycle in surface temperature.


Preparation of Figures

Upon submission of an article, authors are supposed to include all figures and tables in the PDF file of the manuscript. Figures and tables should not be submitted in separate files. If the article is accepted, authors will be asked to provide the source files of the figures. Each figure should be supplied in a separate electronic file. All figures should be cited in the paper in a consecutive order. Figures should be supplied in either vector art formats (Illustrator, EPS, WMF, FreeHand, CorelDraw, PowerPoint, Excel, etc.) or bitmap formats (Photoshop, TIFF, GIF, JPEG, etc.). Bitmap images should be of 300 dpi resolution at least unless the resolution is intentionally set to a lower level for scientific reasons. If a bitmap image has labels, the image and labels should be embedded in separate layers.


Preparation of Tables. 

Tables should be cited consecutively in the text. Every table must have a descriptive title and if numerical measurements are given, the units should be included in the column heading. Vertical rules should not be used.


Units of Measurement. 

Units of measurement should be presented simply and concisely using System International (SI) units.



Lengthy mathematical analyses whose details are subordinate to the main theme of the paper should normally appear in an appendix. Each appendix should have a title.



Copies of the proofs will be sent to the author. Revised proofs should be returned to the publisher without delay. The only changes that could be accepted in proofs are on grammar or related to printing errors.
