The Trocar, powered by ISGE and its members. The Trocar groups the articles in several editions on a yearly basis. While all articles can be accessed through the Open Access Journal, we also group these into specific editions. Every edition is accompanied by an introduction of someone from the editorial board. We also have the opportunity to show the sponsor of the current edition. If you are searching for something specific, you can browse all articles in the Open Access Journal, or if you want have a look at the latest articles; read the latest edition and don't forget to have a look at the add of our sponsor.
