International Journal of Biological and Environmental Engineering has established a unique medium for the publication of new developments and advances in biological and environmental engineering. All submitted papers should report original, previously unpublished research results, experimental or theoretical. Papers submitted to the journal should meet these criteria and must not be under consideration for publication elsewhere. Papers should follow the style of the journal and are subject to both review and editing. Interdisciplinary papers as well as papers that illustrate the application of new and important statistical methods using real data are strongly encouraged.
