Hereditary properties inherited by the lower radical generated by a class M have been considered in [2, 5, 6, 7, 9, 10, 12]. Here we consider the dual problem, namely strong properties which are inherited by the upper radical generated by a class M.</span></p>}, number={1}, journal={Proyecciones (Antofagasta, On line)}, author={Zulfiqar, Muhammad}, year={2011}, month={Jan.}, pages={49-56} }
