Author Guidelines

Submission of manuscripts in soft (electronic) format is preferred. Author(s) are requested to send an email with an electronic version of the manuscript directly to:


  • Authors have to follow either the below-mentioned guidelines to submit their manuscripts or use this template, and provide 3-5 names of the reviewers by filling out this form.
  • Authors of accepted papers MUST revise and re-submit their manuscripts according to the above-mentioned template.


Length of Manuscript

Papers submitted for publication in TJER could be up to ten printed pages or 24 to 30 double spaced pages. It is advisable that authors use the manuscript perpetration guideline in order to reduce the amount of time spent on typesetting the manuscript. The font sizes and the manuscript specifications are outlined as follows.

Typing and Font Specification

Manuscripts should be typed double-spaced on one side of a sheet only, with margins of about 2.5 cm on each side of each page. The font should be Times New Roman for all the components of the manuscript with font size of 12 pt and regular attribute for the body of the text.

Elements of the Manuscript

Full length papers generally consist of the title, author(s) affiliation(s), abstract, keywords, nomenclature if applicable, introduction, body, conclusion,  references, list of figures and table captions, and original figures and tables for reproduction. A  paper may also include appendices and acknowledgments.


Capitalize the first letter of each word, i.e. use title case.

Author Names and Affiliation(s)

Author names on technical papers should include the name of each author followed by his/her company affiliation. If two or more authors have the same  company affiliation, it should not be repeated after each name. Do not use titles such as Mr.,  Mrs., Ms., Miss, Prof. or Dr.


The  abstract  should  be  limited  to  300  words  and  must concisely state what was done, how it was done, principal results, and their significance. The  abstract will appear later in various indices of abstracts and should contain the most critical  information within the paper.


Leave two blank lines after the abstract and type 6-10 key words and phrases (separated by semicolons) that can be used to index the paper, listing the  keywords in order of importance for indexing. Do not repeat words or strings of words from the  title. Capitalize the first letter of each word.


Please include a brief summary of the main points of the paper, do not replicate the abstract as the conclusion, and consider elaborating on the  translational importance of the work or suggest applications and extensions.


The  same  format  as  the  body  of  the  text  should  be followed.


A separate nomenclature section should list in detail the symbols used in the manuscript, their definitions, and their units in SI system. The nomenclature list should be an alphabetical order with Greek symbols following the alphabetical listing.

Subscripts and superscripts should follow Greek symbols and should be identified with a heading.


The references should be included at the end of the manuscript in a separate section named References without a number. All references must be listed alphabetically by last name of the first author. Ensure that the reference information is complete and accurate, including as necessary and in the following order: first names and initials of all authors; year of publication; title of paper, report, or book chapter (in quotes); title of book or periodical (in italics); volume and issue numbers; name and location of publisher (for books), name and location of publisher or sponsor (for proceedings), or city of publication and inclusive page numbers.


All figures must be cited in the body of the paper. Figures should be numbered in Arabic numerals in the order in which they are cited. Related figures or figure sections may be labeled with a shared numeral and consecutive lowercase letters (eg. Figs. 1a through 1d). Figures should be the smallest size possible without loss of clarity, preferably designed to occupy a single column (8.2 cm of width) of a printed journal page. Once the paper is accepted for publication, separate file for each figure in .tif or .tiff format is to be submitted to the technical editor for final printing.


All tables must be cited in the body of the paper. Tables should be numbered in Arabic numerals in the order they are cited in the paper. Tables should be the smallest size possible without loss of clarity. Table headings and column headings should be as concise as possible. Column alignment should be obtained using tabs NOT spaces. Tables should be designed to occupy a single column or the full width of the page. Care should be taken to avoid any arrangement that unduly increases the depth of a table. Use 10-point Times New Roman bold, centered, for table headings and 10- point Times New Roman for body in tables.

Mathematical Notations and Equations

To avoid errors in editing and typesetting, authors should clearly identify subscripts, superscripts, Greek letters, and other symbols.

Equations should be numbered using Arabic numerals placed in parentheses. Break equations to fit within the page. Avoid ambiguities in equations and fractions in text through careful use of parentheses, brackets, solids (slants), etc.

Note that in-text, fractions are usually “broken down” to fit in one line and confusion can result if terms are not properly labeled. The conventional order of brackets is {[0]}.

Units and Abbreviations

The International System of Units (SI units) is required. Unit symbols should be used with measured quantities, i.e. 1 mm, but not when unit names are used in text without quantities, i.e. “a few millimeters.” Acronyms and abbreviations should be defined the first time they are used in the text.


Submission Preparation Checklist

As part of the submission process, authors are required to check off their submission's compliance with all of the following items, and submissions may be returned to authors that do not adhere to these guidelines.

  6. If submitting to a peer-reviewed section of the journal, the instructions in Ensuring a Blind Review have been followed.
