TYPES OF MANUSCRIPT
A research article is an original full length research paper which should not exceed 5000 words in length (including table and fgures in good resolution). Research article should be prepared according to the following order: title, authors name and afliations, abstract, keywords, introduction, materials and method, result and discussion, conclusion, acknowledgement (optional), and references.
A review paper is an invited article up to 5000 words (including table and fgures in good resolution). Review paper summarizes the current state of knowledge of the topic supported by up-to-date and reliable references. It creates an understanding of the topic for the reader by discussing the fndings presented in recent research papers. A review paper synthesizes the results from several primary literature papers to produce a coherent argument about a topic or focused description of a feld.
A short communication is a condensed version of research article, written without chapters, up to 3500 words (including table and fgures in good resolution).
It consists of title, authors name and affliations, abstract, keywords, main content, and references. The main content of the article should represent introduction,
materials and method, result and discussion, and conclusion, prepared without headings. A short communication should con-tribute an important novelty for science, technology, or application.
The authors are fully responsible for accuracy of the content. Any correspondence regarding the manuscript will be addressed to the correspondent author
who is clearly stated including his/her email address, telephone and fax number (including area code), and the complete mailing address. The correspondent
author will handle correspondence with editor during reviewing process. The author are required to suggest two potential reviewer names including their email address.
