Given the experience we have since 2020, we agreed that August is the safest month to hold scientific conferences in Burgas, Bulgaria. The goal is to guarantee to ensure our attendees, partners, and staff's health and safety. Following a discussion, the Organizing Committee approved the conduct of the following scientific conferences in 2021: Agriculture and Food, 9th International Conference, 16-19 August - Read More; Ecology and Safety, 30th International Conference, 16-19 August - Read More; Materials, Methods and Technologies, 23rd International Conference, 19-22 August - Read More; Economy and Business, 20th International Conference, 22-25 August - Read More; Education, Research and Development, 12th International Conference, 25-28 August - Read More; Language, Individual, and Society, 15th International Conference, 25-28 August - Read More
With COVID-19, many scientists may encounter travel difficulties. Therefore, we decided to allow participants to change the type of presentation (oral, poster, or online) up to 20 days before the conference's actual date. Online participants can present oral presentations and posters; they will receive all printed materials (program, certificate, etc.) from the event and publish their papers. There is no limit to the number of changes allowed in the presentation type.
