From the first year, in 1996, it has reflected the facultie’s life and events. Probably the most important change of the conference image is its gradual increase of the number of sections, connected with the implementation of new courses. Recently, increased number of the participants is welcomed, from our University, from partner universities in the Czech Republic and from abroad, respectively. The mission and the aims of the Conference continue. It provides students with the opportunity to present their contributions in face of their colleagues and scientific commissions. Students acquire experience with active presentation and defence of results obtained from research on diploma and doctoral thesis. The discussions among participants and students are very valuable because it is the best training procedure for proper thesis defence in front of the commission. The MendelNet 2011 Conference is an ideal form for scientific survey acquirement in a given specialization. Prof. Ing. Ladislav Zeman, CSc.
