Author instructions for the Revista Colombiana
de Biotecnología
The Revista Colombiana de Biotecnología only publis-hes original articles, mainly contributions from research and development (R&D) in biotechnology's diverse areas, as well as technical articles not necessarily orientated towards proving hypotheses (i.e. technical descriptions of methods). Brief notes will also be accep-ted, such as reports concerning significant work having short-term objectives.
Authors must follow the following instructions; arti­cles not complying with them will be returned without being evaluated. Manuscripts must be submitted in tri­plicate, on letter-sized (21.6 x 27.5 cm), white paper; they must be single-spaced, with 3 cm margins. Two co­pies must omit author details. An electronic copy of the work must also be submitted on diskette or CD. A copy can also be sent to the e-mail address given at the end of these instructions to speed-up the evaluation pro-cess. The articles must be processed using Word for Windows or a compatible application, written in Times New Roman, font-size 12.
The work must not exceed a maximum of 20 pa-ges, including Figures, Tables and Bibliography. The language used must be clear and precise and the work must be written in the third person. The past tense must be used for the Introduction, Materials and Methods and Results sections.
Commercial names and brand-names must be avoided in the body of the text (or referred to in parent-hesis). Commercial products must be referred to by the technical name or the main ingredient (initial lettercapi-talised). Only internationally accepted abbreviations must be used. In the case of little-known acronyms being used, they must be written in full the first time that they are used, followed by the acronym in parenthesis. All acronyms and abbreviations must be written without a full-stop following them. The metric decimal system must be used for all measurements and those abbrevia­tions for common units of measurement: kilogram (kg), gram (g), milligram (mg), meter (m), etc. Avoid footno-tes, except for information regarding authors of an arti-cle. Use a single letter size.
The article's structure must follow the accepted steps used by Scientific Method, thus:
Title. It must be short but illustrative, without ex-ceeding 15 words. This title must then be translated into Spanish and a short title for the pageheadings must also be included.
Authors. The complete names must be included when crediting the authors of any article. The authors must be listed in agreement with the importance of their contribution to the research or in the preparation of the article and not in alphabetical order, nor in terms of rank. Their respective academic distinctions, the institution to which they belong and their complete mailing address (including e-mail) must be marked byanasteriskand gi­ven in a footnote.
Abstract in English. This must be concise and contain information concerning the research's justifica-tion, objectives, methodology and concrete results. It must indicate the main conclusions, emphasising achie-vements. It must not exceed 250 words, these to be written in a single paragraph.
Key words in English. There must be a list con-taining a maximum of five key words from the article (dif-ferent to those included in the title) facilitating the use of modern computerised cataloguing and information search systems.
Abstract in Spanish. This must be a technical translation of the abstract to the Spanish language.
Key words in Spanish. There must be a faithful translation of the key words to the Spanish language.
Introduction. This must describe the general pur-pose for writing on the subject, giving the necessary in­formation precisely, referring only directly to that related literature considered indispensable for developing the subject, allowing the present state of the same to beco-me known. It must clearly indicate the objective of the research's hypothesis and its relationship with other re-levant work (it must not include extensive reviews of the bibliography).
Materials and Methods. The techniques and the equipment used must be described in a sequence spe-cifically and logically showing the research's develop­ment so that they can be reproduced. The materials' sources, their state of purity and the detailed description of equipment must only be included when these are very specific or novel. Procedures described by other authors must be avoided; but, if they have been modi-fied, then the details of such modification must be included.
Results and Discussion (the Discussion can be given as a separate section). Experimental results must
only appear in Tables and Figures when these are ab-solutely necessary; they must be succinctly but comple-tely explained in the text. When results are sustained by statistical calculation, the origin of the data and the sta-tistical method used must be mentioned. The Tables must be given a title and be identified by continuous Arabic numbers. The Figures (photographs, drawings, graphs and maps) must appear with a title and be identi­fied by Arabic numbers. Figures processed by compu-ter (when these are printed with high quality characteris-tics, preferably by laser printer) are accepted. Black and white photographs are accepted. If it is necessary to in-clude colour photographs then the author must pay the printing costs. The discussion must be brief and limited to the work's significant aspects.
Conclusions. They must be based on the results obtained. If it is possible, they must offer a solution to the problem outlined in the Introduction.
Acknowledgements. If it is necessary to show gratitude to people or institutions making a significant contribution towards the work, these must be kept short and concrete.
Bibliographical references in the body of the Text. Only published references can be accepted, mentioning the author's last name, followed by the year of publica-tion in parenthesis, for example: Rodríguez (1997). When there are three or more authors, the Latin expres-sion et al. must be used, for example: López et al. (1996). If the reference is made at the end of a phrase, author and date are given in parenthesis, for example: (Rodríguez 1997; López etal. 1996).
Bibliography. This must be presented in alpha-betical order of first-named authors. Its presentation must be as follows.
For articles. Author(s), year, title of the article, journal, volume, number, page(s), i.e. Pérez, R.; Lalu-cat, J. 1980. Genes as assassins of free life. 44 (4): 38-45.
Books., Author (s), yearof publication, title, place where printed, the publisherororganisation responsible for the publication, pages, i.e. Gómez A.; Posada, H. 1987. Chinchiná, Colombia: Cenicafé.p. 481.
A thesis must be referred to as if it were a book.
If any work has special characteristics and there-fore cannotfulfil all those specifications previously indi-cated, then it is recommended that at least title, aut-hor(s), abstract, key words, translations of the abstract
and key words, bibliographical appointments and con-clusions should be given.
Articles dealing with topic review
Topic review articles will only be accepted for publica­tion when requested by the Editorial Committee. Aut­hors may however propose topics, indicating the purpo-se of such reviews and the reference sources and search methods to be used. The Editorial Committee will evaluate any such proposal and determine whether it should be developed and/or included in the journal.
According to Colciencias, review articles are do-cuments resulting from research, analysing, systemati-sing and integrating the results of published and unpu-blished research in a scientific ortechnological field so as to take account of advances and trends in R&D. They mustfulfil the following characteristics.
Reviews must be between 12 and 20 pages long. Contents: they must have a Summary emphasising the significance of recent findings; an Introduction; a sec-tion for Critical Analysis (presented under subtitles or in sections); Conclusions; and a Bibliography, including at least 50 references, the majority being recent (i.e. pu­blished within the last five years in the case of well-known topics). Schemes, Figures and Tables should also be included, dynamising the text and facilitating un-derstanding. A review should integrate the compiled in-formation and give a detailed explanation of the limita-tions and any incongruence found in published studies' results.
The Revista Colombiana de Biotecnología is a peer-reviewed publication. Those articles received are sent (without authors' names) to anonymous peereva-luators selected by the Editorial Committee. Their ob-servations are then sent to authors so that they can make the corresponding modifications. The Editorial Committee takes the final decision whether to publish a particular article.
