Study themes in multilanguages, illustrated with simulation programs, interaction or animation for group or individual educational activity. This mutidiscipline publication is frequently expanded. Its objective is to educate with participation of the interested person, in a dynamical way, with low cost, enabling wide, fraternal and constructive communication. With the increasing quality of Teleeducation due to general progress there is hope to contribute for a better life quality. The team received mail from people of several countries. We have attended and will continue to attend the users with pleasure and respect. Authors of selected collaborations may be invited by the team to publish in this space.
