El presente documento, parte de la experiencia de trabajo realizado el 2024 en la Estrategia para el fortalecimiento de la gestión de la convivencia escolar, la prevención y la atención de la violencia en las instancias de gestión educativa descentralizada del Ministerio de Educación. Fue en este espacio, donde encontré que se había instalado una cultura del silencio ante situaciones de violencia que ocurría en las escuelas en las que me tocó participar. Esta cultura la encontré en todas las Instituciones Educativas. En este documento, narro cómo es esa cultura, qué hizo posible que se instalara, cómo se desarrolla y cómo se sigue reproduciendo. Pero también, menciono, qué camino o salidas posibles se pueden tomar para hacer que la cultura del silencio no siga siendo un factor de riesgo.

In the present work the catalytic behavior of the system Ni-Cu/supported on clay and alumina has been studied. The catalysts were prepared at a concentratlon of 1O% W of metalllc content. The method used in the preparation was impregnatlon, starting form the corresponding nitrates followed by a subsequent drying and calclnation. The elemental quantitative analysis was accomplished by Atomic Absorption. The presence of the phases NIO and CuO was confirmed by DRX. The activity of the catalysts were tested in a batch reactor at 455 ºK and 500 r.p.m. for 200 ml/min of hydrogen during 2 and 4 hours. The greater activity was observed in the catalyst with a theoretical molar fraction of 0.75 with respect to the nickel, in whlch is observed a decrease of the iodine index of the sunflower oil from 84.28 to 56.95 in a period of 4 hours.
