In accordance with major definitions of open access in scientific literature (namely the Budapest, Berlin, and Bethesda declarations), Sciences Force defines open access by the following conditions: peer-reviewed literature is freely available without subscription or price barriers, literature is immediately released in open access format (no embargo period), and published material can be re-used without obtaining permission as long as a correct citation to the original publication is given. most articles published by Sciences Force contained the note: "© year by Sciences Force. Reproduction is permitted for noncommercial purposes". Sciences Force journals started to publish articles under the Creative Commons Attribution License and are now using the latest version of the CC BY license, which grants authors the most extensive rights. This means that all articles published in Sciences Force journals, including data, graphics, and supplements, can be linked from external sources, scanned by search engines, reused by text mining applications or websites, blogs, etc. free of charge under the sole condition of proper accreditation of the source and original publisher. Sciences Force believes that open access publishing fosters the exchange of research results amongst scientists from different disciplines, thus facilitating interdisciplinary research. Open access publishing also provides access to research results to researchers worldwide, including those from developing countries, and to an interested general public. Although Sciences Force publishes all of its journals under the open access model, we believe that open access is an enriching part of the scholarly communication process that can and should co-exist with other forms of communication and publication, such as societybased publishing and conferencing activities. Important Note: some articles (especially Reviews) may contain figures, tables or text taken from other publications, for which Sciences Force does not hold the copyright or the right to re-license the published material. Please note that you should inquire with the original copyright holder (usually the original publisher or authors), whether or not this material can be re-used.
