Abstract: A material that is less populated by biofilms than known materials and is well tolerated by the body is provided. The material is an element introducible into or attachable on a human or animal body and includes a glass and/or glass ceramic and/or ceramic material at least in some areas thereof, which inhibits the formation of biofilms and/or on which human or animal cells grow if the element is introduced into the human or animal body or attached thereto, wherein the glass and/or glass ceramic material comprises at least: SiO2 in a range from 60 to 75 wt % and ZnO in a range from 1 to 7 wt %.

Abstract: An interruption device arranged in a communication line including first and second cables in series, each including a first group of wires for the transmission of computer data and a second group of wires independent of the computer data, includes: a box provided with first and second input/output sockets with which the first and second cables, respectively, are connected; interrupters each connected between the first and second input/output sockets inside the box and actuable from outside the box, these interrupters being associated respectively with the wires of the first group; and transmission elements not including an interrupter and each connected between the first and second input/output sockets inside the box, these transmission elements being associated respectively with the wires of the second group. In a variant, the second input/output socket is replaced by two sockets associated with the interrupters and the transmission elements, respectively.
