COVERING LETTER: It is a mandatory requirement that a signed covering letter also be submitted along with the manuscript by the  author to whom correspondence is to be addressed, delineating the scope of the submitted article declaring the potential competing interests, acknowledging contributions from authors and funding agencies, and certifying that the paper is prepared according to the 'Instructions for Authors'.  All inconsistencies in the text and in the reference section, and any typographical errors must be carefully checked and corrected before the submission of the manuscript.  The article contains no such material or information that may be unlawful, defamatory, fabricated, plagiarized, or which would, if published, in any way whatsoever, violate the terms and conditions as laid down in the agreement.  The authors acknowledge that the publishers have the legal right to take appropriate action against the authors for any such violation of the terms and conditions as laid down in the agreement. Download the Covering letter

TITLE: The title should be precise and brief and must not be more than 120 characters. Authors should avoid the use of non-standard abbreviations. The title must be written in title case except for articles, conjunctions and prepositions.

Authors should also provide a short ‘running title’.

ABSTRACT: The abstract should not exceed 250 words for review and research papers and should be limited to only 150 words for letters, summarizing the essential features of the article. The use of abbreviations should be reduced to a minimum and the references should not be cited in the abstract.

KEYWORDS: Provide 6 to 8 keywords in alphabetical order.

TEXT ORGANIZATION: The main text should begin on a separate page and should be divided into separate sections. For Research articles, the preparation of the main text must be structured into separate sections as Introduction, Materials and Methodology, Results, Discussion and Conclusion. For Review and Letter articles, the manuscript should be divided into title page, abstract and the main text. The text may be subdivided further according to the areas to be discussed, which should be followed by the Acknowledgement (if any) and Reference sections. The review article should mention any previous important reviews in the field and contain a comprehensive discussion starting with the general background of the field. It should then go on to discuss the salient features of recent developments. The authors should avoid presenting material which has already been published in a previous review. The authors are advised to present and discuss their observations in brief. The manuscript style must be uniform throughout the text and 10 pt Times New Roman font should be used. The full term for an abbreviation should precede its first appearance in the text unless it is a standard unit of measurement. The reference numbers should be given in square brackets in the text. Non-assimilated words from Latin or other languages should also be italicized e.g., per se, et al. etc.

Symbols and Units: Greek symbols and special characters play a prominent role in the manuscript. These symbols often undergo formatting changes and get corrupted or lost during preparation of a manuscript for publication. To ensure that all special characters used are embedded in the text, these special characters should be inserted as a symbol but should not be a result of any format styling (Symbol font face) otherwise they will be lost during conversion to PDF/XML².

Authors are encouraged to consult reporting guidelines. These guidelines provide a set of recommendations comprising a list of items relevant to their specific research design. All kinds of measurements should be reported only in International System of Units (SI).

Equations and Mathematical Expressions:

1. Avoid the use of built-up fractions in the text. If not avoided by the author(s), built-up fractions will be converted to equivalent expressions on the line when the paper is copyedited. In display matter, however, built-up fractions are preferred for clarity.

2. Avoid the use of small-type mathematical expressions centered above or below arrows. If possible, try to use an alternative format.

3. In the exponential function, avoid exponents having more than one or two characters.

4. Avoid the use of reference numbers for equations that are not subsequently referred to in the paper. Costs are reduced if short mathematical equations and other expressions in the text are run in (instead of each being displayed on a separate line). Authors must expect that, when accepted papers are copyedited, "excess" equation reference numbers will be deleted and short equations will be run in with text.

5. Be sure to indicate special marking for symbols (e.g., italics, boldface) and clearly identify any unusual symbols. Try to avoid underscored symbols because they often require hand composition and opening up lines and thus are expensive. In vector notations, indicate which letters or notations, if any, may be set in boldface type. Indicate if asterisks are to be set in superscript position or centered on the line.

6. All equations should be indented and numbered as follows: (1)

7. Equation number should be right justified. Put three dots(...) midway between the end of the equation and the equation number.

8. Punctuation should not be used at the end of an equation.

9. Particular care should be taken to distinguish between the number zero (0) and the letter O; the number one (1) and the letter l, the Roman letter v and the Greek letter nu (n). The decimal logarithm should be written "log" and the natural log "ln". The abbreviation of the exponential function is a roman e (for example, e^x) or exp (for example, exp (u² + n)). In expressions of the type dxdt, the letter d (derivative function) is always written in roman, whereas the physical parameter (x or t) is always in italics. Numbers are written in numerals when they are followed by units, these being represented by their SI symbols (10 % but a few percent).

10. In numerals, each group of three letters should be separated by a space (except for dates and postal codes).

11. Authors should provide the equations in *TeX/LaTeX file format separately as well as embedded in the manuscript.

Symbols:

Mathematical symbols must be defined immediately where they are introduced.

Characters:

Character fonts:

The italic font should be used for mathematical symbols (this is the default font in *TeX/LaTeX’s math mode). In addition to variables and constants, the italic font should be used for particle symbols, symbols of quantum states, and group-theoretic designations.

Diacritical signs:

A diacritical sign is a marking placed directly above or below symbols, e.g., the arrow in .



Subscripts and superscripts:

All available characters can be used as subscripts or superscripts.
Position of a subscript or superscript is dictated by standard notation.

Examples:



Abbreviations in math:

Some abbreviations, such as those for mathematical functions and those used in superscripts or subscripts require special handling and are discussed below.

Abbreviations designating mathematical functions:

• Roman multiletter abbreviations must be closed up to the argument following and separated from any preceding symbol by a thin space, that is,

• To treat a function of a function enclose it in bold round parentheses, i.e.,

g(f(x))

• e and exp (for exponent) notation

The e form is appropriate when the argument is short and simple, i.e., e^ik·r, whereas exp should be used if the argument is more complicated.

Equation breaking (multilinear equations):

Mathematical expressions often need to be displayed on two or more lines (“broken”)

The best place for a break is just before an operator or sign of relation. These signs should begin the next line of the equation.

Equation numbering:

A principal equation and subordinate equations may be numbered (1), (1a), (1b), etc.

Bracketing and Grouping sequence:

For the purpose of grouping, the sequence of bracketing preferred is {[()]}, working outwards in sets ( ), [ ], and {}.

{ [ ( { [ ( ) ] } ) ] }

Limits and indices:

In text, however, space limitations require that single limit sums or integrals use subscripts and superscripts, for example

Fractions:

Fractions can be “built up” with a fraction bar, a+b c , “slashed” with a solidus, (a + b)/c, or written with a negative exponent, (a + b)c^__1. In text all fractions must be either slashed or written with a negative exponent.

Multiplication signs:

The primary use of the multiplication sign is to indicate a vector product of three-vectors (e.g., k x A). Do not use it to express a simple product.

The center dot (•) should not be used to mean a simple product. Use the dot to represent inner products of vectors (k • r).

Mathematical terms:

The use of the following standard symbols is recommended.

LIST OF ABBREVIATIONS: If abbreviations are used in the text either they should be defined in the text where first used, or a list of abbreviations can be provided.

CONFLICT OF INTEREST: Financial contributions to the work being reported should be clearly acknowledged, as should any potential conflict of interest.

ACKNOWLEDGEMENTS: Please acknowledge anyone (individual/company/institution) who has contributed to the study by making substantial contributions to conception, design, acquisition of data, or analysis and interpretation of data, or who was involved in drafting the manuscript or revising it critically for important intellectual content. Please list the source(s) of funding for the study, for each author, and for the manuscript preparation in the acknowledgements section.

REFERENCES: References must be listed in the numerical system (Vancouver). All references should be numbered sequentially [in square brackets] in the text and listed in the same numerical order in the reference section. The reference numbers must be finalized and the bibliography must be fully formatted before submission.

See below few examples of references listed in the correct Vancouver style:

E-citations:
[8] Citations for articles/material published exclusively online or in open access (free-to-view), must contain the exact Web addresses (URLs) at the end of the reference(s), except those posted on an author’s Web site unless editorially essential, e.g. ‘Reference: Available from: URL’.

Some important points to remember:

*References must be complete and accurate.
*Online citations should include the date of access.
*Journal titles should conform to the present ACM Guide to Computing Literature/Chemical Abstracts etc. abbreviations.
*If the number of authors exceeds six then et al will be used after three names (the term “et al.” should be in italics).
*Take special care of the punctuation convention as described in the above-mentioned examples.
*Avoid using superscript in the in-text citations and reference section.
*Abstracts, unpublished data and personal communications (which can only be included if prior permission has been obtained) should not be given in the reference section but they may be mentioned in the text and details provided as footnotes.
*The authors are encouraged to use a recent version of EndNote (version 5 and above) or Reference Manager (version 10) when formatting their reference list, as this allows references to be automatically extracted.

APPENDICES: In case there is a need to present lengthy, but essential methodological details, use appendices, which can be a part of the article. An appendix must not exceed three pages (Times New Roman, 12 point fonts, 900 max. words per page).The information should be provided in a condensed form, ruling out the need of full sentences. A single appendix should be titled APPENDIX, while more than one can be titled APPENDIX A, APPENDIX B, and so on.

FIGURES/ILLUSTRATIONS: The authors should provide the illustrations as separate files, as well as embedded in the text file, numbered consecutively in the order of their appearance. Each figure should include a single illustration. No charges will be levied on the use of color figures except in the reprints. Each figure should be closely cropped to minimize the amount of white space surrounding the illustration.

If a figure consists of separate parts, it is important that a single composite illustration file be submitted, containing all parts of the figure.

Photographs should be provided with a scale bar if appropriate, as well as high-resolution component files.

Scaling/Resolution:

For Line Art image type, which is generally an image based on lines and text and does not contain tonal or shaded areas, the preferred file format is TIFF or EPS, with colour mode being Monochrome 1-bit or RGB, in a resolution of 900-1200 dpi.

For Halftone image type, which is generally a continuous tone photograph and contains no text, the preferred file format is TIFF, with colour mode being or RGB or Grayscale, with a minimum resolution of 300 dpi.

For Combination image type, which is generally an image containing halftone in addition to text or line art elements, the preferred file format is TIFF, with colour mode being or RGB or Grayscale, in a resolution of 500-900 dpi.

Formats:

For illustrations, the following file formats are acceptable:

• Illustrator
• EPS (preferred format for diagrams)
• PDF (also especially suitable for diagrams)
• PNG (preferred format for photos or images)
• Microsoft Word (version 5 and above; figures must be a single page)
• PowerPoint (figures must be a single page)
• TIFF
• JPEG (conversion should be done using the original file)
• BMP
• CDX (ChemDraw)
• TGF (ISIS/Draw)

Bentham OPEN does not process figures submitted in GIF format.

If the large size of TIFF or EPS figures acts as an obstacle to online submission, authors may find that conversion to JPEG format before submission results in significantly reduced file size and upload time, while retaining acceptable quality. JPEG is a 'lossy' format, however in order to maintain acceptable image quality, it is recommended that JPEG files are saved at High or Maximum quality.

Files should not be compressed with tools such as Zipit or Stuffit prior to submission as these tools will in any case produce negligible file-size savings for JPEGs and TIFFs, which are already compressed.

Image Conversion Tools:

There are many software packages, many of them freeware or shareware, capable of converting to and from different graphics formats, including PNG.

Good general tools for image conversion include GraphicConverter on the Macintosh, PaintShop Pro, for Windows, and ImageMagick, which is available on Macintosh, Windows and UNIX platforms.

Note that bitmap images (e.g. screenshots) should not be converted to EPS, since this will result in a much larger file size than the equivalent JPEG, TIFF, PNG or BMP, with no increase in the quality. EPS should only be used for images produced by vector-drawing applications such as Adobe Illustrator or CorelDraw. Most vector-drawing applications can be saved in, or exported as, EPS format. In case the images have been originally prepared in an Office application, such as Word or PowerPoint, then the original Office files should be directly uploaded to the site, instead of being converted to JPEG or another format that may be of low quality.

Chemical Structures: Chemical structures MUST be prepared according to the guidelines below.

Structures should be prepared in ChemDraw and provided as separate file, submitted both on disk and in printed formats.

SUPPORTIVE/SUPPLEMENTARY MATERIAL: We do encourage to append supportive material, for example a PowerPoint file containing a talk about the study, a PowerPoint file containing additional screenshots, a Word, RTF, or PDF document showing the original instrument(s) used, a video, or the original data (SAS/SPSS files, Excel files, Access Db files etc.) provided it is inevitable or endorsed by the journal's Editor.

Published/Reproduced Material should not be included unless you have obtained written permission from the copyright holder, which must be forwarded to the Editorial Office in case of acceptance of your article for publication.

Supportive/Supplementary Material intended for publication must be numbered and referred to in the manuscript but should not be a part of the submitted paper. In-text citations as well as a section with the heading "Supportive/Supplementary Material" before the "References" section should be provided. Here, list all Supportive/Supplementary Material and include a brief caption line for each file describing its contents.

Any additional files will be linked into the final published article in the form supplied by the author, but will not be displayed within the paper. They will be made available in exactly the same form as originally provided only on our Web site. Please also make sure that each additional file is a single table, figure or movie (please do not upload linked worksheets or PDF files larger than one sheet). Supportive/Supplementary material must be provided in a single zipped file not larger than 4 MB.

Authors must clearly indicate if these files are not for publication but meant for the reviewers'/editors' perusal only.

PERMISSION FOR REPRODUCTION: Published/Reproduced Material should not be included unless you have obtained written permission from the copyright holder, which should be forwarded to the Editorial Office in case of acceptance of your article for publication.

For obtaining permission for reproducing any material published in an article by Bentham Science Publishers, please fill in the request FORM and send to tohydj@benthamopen.org for consideration.

AUTHORS AND INSTITUTIONAL AFFILIATIONS: The author will be required to provide their full names, the institutional affiliations and the location, with an asterisk in front of the name of the principal/corresponding author. The corresponding author(s) should be designated and their complete address, business telephone and fax numbers and e-mail address must be stated to receive correspondence and galley proofs.

REVIEWING AND PROMPTNESS OF PUBLICATION: All manuscripts submitted for publication will be immediately subjected to peer-reviewing, usually in consultation with the members of the Editorial Advisory Board and a number of external referees. Authors may, however, provide in their Covering Letter the contact details (including e-mail addresses) of four potential peer reviewers for their paper. Any peer reviewers suggested should not have recently published with any of the authors of the submitted manuscript and should not be members of the same research institution.

All peer-reviewing will be conducted via the Internet to facilitate rapid reviewing of the submitted manuscripts. Every possible effort will be made to assess the manuscripts quickly with the decision being conveyed to the authors in due course.

LANGUAGE AND EDITING: Manuscripts must be written in good English in a clear and correct style. In order to maintain uniformity throughout the text, the manuscript should be written in either American or British English. Submitted manuscripts will not be edited for style or language, and reviewers may advise rejection of a manuscript if it is compromised by grammatical errors. Non-native speakers of English may choose to make use of a copyediting and language editing service such as that provided by Bentham Publishing Services (please contact at email: info@benthampublishingservices.com).

PROOF CORRECTIONS: Authors are required to proofread the PDF versions of their manuscripts before submission. To avoid delays in publication, proofs should be checked immediately for typographical errors and returned within 48 hours. Major changes are not acceptable at the proof stage. If unable to send corrections within 48 hours due to some reason, the author(s) must at least send an acknowledgement on receiving the galley proofs or the article will be published exactly as received and the publishers will not be responsible for any error occurring in the manuscript in this regard.

The corresponding author will be solely responsible for ensuring that the revised version of the manuscript incorporating all the submitted corrections receives the approval of all the authors of the manuscript.

COPYRIGHT: Authors who publish in Bentham OPEN Journals retain copyright to their work. Submission of a manuscript to the respective journals implies that all authors have read and agreed to the content of the Covering Letter or the Terms and Conditions. It is a condition of publication that manuscripts submitted to this journal have not been published and will not be simultaneously submitted or published elsewhere. Plagiarism is strictly forbidden, and by submitting the article for publication the authors agree that the publishers have the legal right to take appropriate action against the authors, if plagiarism or fabricated information is discovered.
