Authors Instructions

All manuscripts are written in English. Submissions should be accompanied by a statement from the authors that the work has not been previously published in any form and all authors are in agreement with its submission. Authorship should be restricted to those who have made significant contributions to the research (i.e. conceptualization, experimental design, data collection and analysis, writing).The manuscript should include the following: title, author’s name(s) and biography, company or institute, abstract and key words. The main parts of the manuscript should consist of introduction, materials and methods, results, discussion, (or results and discussion) conclusion, acknowledgement, figures and tables with captions and descriptions, in which detailed quantity, amount and unit will be given.


Manuscripts should be submitted as Microsoft Word & pdf compatible documents. The manuscripts should be double-spaced, with a minimum of 2.5 cm margins on all sides.

Title Page

The title page should include title, author(s)’ name and affiliation, email address of the corresponding author and a suggested running head (Maximum 50 characters). When the title contains reference to an organism, give taxonomic affiliation in parentheses. Please do NOT use case capitals for either the title or authors names.


An informative abstract shorter than 250 words is included. Informative abstracts include the purpose of the research, the main methods used, the most important results, and the most significant conclusions.


Supply 3 to 7 keywords that describe the main content of the article. Select words different than those in the title and list them alphabetically.


Should be precise, clear, and concise. Avoid verbiage, excessive citations of the literature (especially to support well known statements), discussions marginally relevant to the paper, and other information that adds length but little substance to the paper. All tables and figures should be relevant and necessary; do not present the same data in tables and figures, and do not use short tables for information that can be easily presented using text.

Material & Methods

The nomenclature, the source of material and equipment used, with the manufacturers’ details in parenthesis, should be clearly mentioned. The procedures adopted should be explicitly stated to enable other workers to reproduce the results, if necessary. New methods may be described in sufficient detail and indicating their limitations. Established methods can be just mentioned with authentic references and significant deviations, if any given, with reasons for adopting them. While reporting experiments on human subjects and animals, it should be clearly mentioned that procedures followed are in accordance with the ethical standards laid down by the national bodies or organizations of the particular country. Whenever needed, appropriate certification should be provided at the time of submission of the manuscripts.

The statistical analysis done and statistical significance of the findings when appropriate should be mentioned. Unless absolutely necessary for a clear understanding of the article, detailed description of statistical treatment may be avoided. Articles based heavily on statistical considerations, however, need to give details particularly when new or uncommon methods are employed. Standard and routine statistical methods employed need to give only authentic references.


Only such data as are essential for understanding the discussion and main conclusions emerging from the study should be included and arrange in unified and coherent sequence so that the report develops clearly and logically. Data presented in tables and figures should not be repeated in the text. Only important observations need to be emphasized or summarized. The same data should not be presented both in tabular and graphic forms. Interpretation of the data should be taken up only under the Discussion and not under Results.


The discussion should deal with the interpretation of results without repeating information already presented under Results. It should relate new findings to the known ones and include logical deductions. It should also mention any weaknesses of the study.

The conclusions can be linked with the goals of the study but unqualified statements and conclusions not completely supported by the data should be avoided. Claiming of priority on work that is ongoing should also be avoided. All hypotheses should, if warranted, clearly be identified as such; recommendations may be included as part of the Discussion, only when considered absolutely necessary and relevant.


Acknowledgment should be brief and made for specific scientific/technical assistance and financial support only and not for providing routine departmental facilities and encouragement or for help in the preparation of the manuscripts (including typing or secretarial assistance).


Tables should have no vertical lines and only three horizontal lines (under the title, under the headings of the columns, and at the end of the table). Fill blank spaces with a dash and explain its meaning at the end of the title or in a footnote.


Preparation: Similar figures should be arranged into plates whenever possible; leave very little space between adjoining illustrations or separate them with a thin white line. Line art should be scanned at 900 dpi, photographs (halftone or color) at 300 dpi, and figures with line art and halftones at 600 dpi. Crop the illustrations to remove non printing borders. Make lines thick enough and text large enough to compensate for reduction. Dimensions of the original artwork should not exceed 28 cm x 21.5 cm; the printed area of the journal page measures 20.3 x 14 cm. Submission: TIFF or JPG files of figures should be of high quality and readable in Adobe Photoshop. Do not embed figures in the manuscript document.

The figures will be evaluated during the editorial reading of the article and if necessary instructions will be provided for the submission of adequate illustrations. Authors must pay the additional cost of printing color illustrations (approximately US $ 40 per page and for domestic paper: BDT 700 per page).


The authors will also happy to know that iJNS authority also reduced online version publication fee of only BD Taka 1500/= (BD Taka One Thousand Five Hundred only) until further notice. In that case authors have to deposit BD Taka 500/= (BD Taka Five Hundred only) as reviewer fee along with the submission of their articles to our designated bank (Dutch Bangla Bank Limited, Branch: Sylhet, Account name: International Journal of Natural Science (IJNS), Account number: 121.110.16680).

Authors’ Contributions

All authors are encouraged to specify their individual contributions at the bottom of the title page or on a separate page. The iJNS will not publish an item unless it has the signatures of all the authors. Participation solely in the acquisition of funding or the collection of data does not justify authorship. General supervision of the research group is also not sufficient for authorship. Any part of an article critical to its main conclusions must be the responsibility of at least one author.
