Original Articles: Original Articles must present scientific results that are essentially new and that have not been published or are being considered for publication elsewhere.
Reviews: Reviews are usually commissioned by the Editor or an Editorial Board member, but the submission of proposals for Reviews is very much encouraged.
Short Communications: Short Communications are short papers that present significant new observations.
Case Studies: Case Studies provide relevant material to support both research and education through the transferability of experiences, events and experiments and highlight the essence and core findings of research.
