Avances en Ciencias e Ingeniería-ACI (ISSN: 0718-8706), Advances in Science and Engineering is a journal oriented to diffuse scientific and technological work in Sciences and Engineering (in different areas such as: Chemistry, Physics, Biotechnology, Materials, Polymers, Environment and Pollution, Simulation, Thermodynamics, among others). The Journal also includes topics related to Teaching and College Education (Science Didactics, proposals for improvement in college education, teaching methodology, teaching simulation, etc.). ACI is a forum for Ibero -American researchers to share the researches’ results they develop (supported by their respective institutions and government entities).
Visión y Misión de ACI
ACI’s mission is to propagate researches developed in different countries, by placing an international forum available for Ibero -American teachers, researches and professionals.
ACI’s vision is, through publications, to give place to interactions among researchers, teachers and professionals, who publish in it, in order to share experiences, disseminate their proposals and investigation works, create working groups, position the institutions they work for and contribute with solutions to the multiple problems that countries face nowadays.
Avances en Ciencias e Ingeniería is an electronic format (on-line), peer-reviewed and serial journal, besides, an open-access publication supported by an International Editorial Board. The official language of the journal is Spanish; all researchers from non Spanish- speaking countries must submit their works duly translated into the official language. The journal’s periodicity is quarterly, which means 4 issues are annually edited and periods are as follows: January-March (Nº1), April-June (Nº2), July-September (Nº3) and October-December (Nº4).

Other considerations Avances en Ciencias e Ingenieria (ACI)

Other considerations
Hereby, there’s information relating to the works which are not selected to be published in the journal. The failure to publish a manuscript in Avances en Ciencias e Ingeniería can be attributed to three reasons: 1) negative evaluation of the referees (and, therefore, work is not publishable), 2) due to work’s withdrawal by the authors, at any stage or 3) due to inappropriate behaviors in a publication.
1) Negative evaluation of referees and publication |
Implies that the work evaluation in question, by more than one referee (peer review), has been unfavorable. Referees have indicated various comments and observations that justify their decision. The Editor informs the author the decision not to publish the work in the journal, based on the evaluations. The author can re-submit work for consideration in the magazine, but must restate from past evaluations. This work will be treated as new, and subjected to evaluation in accordance with the procedures described by the journal. |
2) Work withdrawal |
A work will not be published, if the author withdraws it, at any stage of the process (reception, evaluation, modification, and acceptance). |
3) Inappropriate behavior in publications |
Avances en Ciencias e Ingeniería, rejects any publication that has not been carried out in an honest, serious and professional way, what goes against the principles and values that be researchers must follow in general. Therefore, there’s no place in the journal for: replication (full or partial), plagiarism (and self plagiarism), forgery and data, manipulation and any other inappropriate action. When a work and its author have engaged in any dishonest practices, copyright and ethical commitment provided by the magazine violation (acknowledged by the author), the work will be excluded of the publishing process notifying the author and his institution. |
If a work is not published in the journal, for the reason stated in paragraph 1 (negative evaluation), the author shall be entitled a refund of 50% of the payment made for their work (percentage that considers the administrative and operational costs involved in the management of an article), according to the actual amount received by EBS (in the case of wire transfers), or leave this percentage as a credit balance for sending other work. |
No partial (or total) refund will be provided to the author whose work has not been published for the reasons stated in paragraphs 2 and 3. |
Deadline for the authors (negative evaluation of referees and publication) to consider this money (50% of the amount paid) either as refund or credit balance for a new work is 12 months (from date of notification). After that, there is no chance for claiming the money. |
The refund process (for those authors upon request) will be conducted as follows: |

Article evaluation and final versions Avances en Ciencias e Ingenieria (ACI)

Article evaluation and final versions Received articles will be reviewed by international referees (peer- review), who will evaluate the manuscript’s relevance of the content and validity, for which a standard form is used for writing comments and suggestions to the respective authors. The Editor will ensure the compliance of Avances en Ciencias e Ingeniería standards. The articles received must meet the requirements stipulated in the rules, once verified that the jobs are sent to evaluate (a four evaluators). The evaluator selected, it prompts you for the work of arbitration and sent a copy of the work (in pdf format with numbered lines, including the authors and their affiliations). The evaluator must complete a form where their impressions and suggestions delivery, according to the items of the form. The article’s approval is resolved with at least 2 positive evaluations. If two evaluations are different (one approving and other, rejecting the work), a third evaluation is carried out or a new arbitrator is designated (if not having a third evaluation), for the Editor to settle. If a work has two or more negative evaluations, this may not be published. The name of the evaluator (and affiliation) won’t be revealed to the authors. The evaluator receives a certificate for the evaluation carried out. Additionally, the journal’s Editor suggests some aspects of format. The author receives the evaluation’s report and the text edition made by the Editor. Evaluated and accepted works will be sent to authors for modifications, if applicable. Upon receipt of this version, changes are verified, according to the comments and evaluation’s observations. Works meeting all requirements will be assigned to the respective number and volume of the journal. Assignation shall be in strict order of reception. After publishing the article, a copy of the work will be sent to the author (reprint) digitally (in PDF). Final Versions Once the authors have made the changes, they shall send a copy of the edited manuscript (doc and pdf formats), and a letter explaining the changes (attended and unattended ones, duly justified) according to the evaluators’ observations. This will be a free format letter (can be in tabular or prose), but they should clearly specify to whom is the answer addressed to (to the Editor, Evaluator1, Evaluator2, etc). Deadline for sending the modified version is 2.5 months. After that time, if the modified version is not received, the author shall be deemed to remove the work from the process. However, the author may request an extension in attention to reasons which may delay sending the modified version, indicating the respective reasons for delay. Release tests Once the modified version of the article is approved, format will be reviewed (for example, presentation and figures and tables placement) for a better presentation and publication impact. The same applies to the article’s first page, where abstract, title and keywords in Spanish and English will be checked. The Editor reserves the right to make changes considered appropriate, without affecting the substance of the article. Once the review is ready, a copy is sent to the author for approval. |
