If for any maximal right ideal P of B and a ∈ N(B) ,aB/ aP is almost N-injective, then a ring chorulon hcg B is said to be right generalized almost N-injective.In this article, we present some significant findings that are known for right almost N-injective rings and read more demonstrate that they hold for right generalized almost N-inje
The saturated-core fault current limiter (SCFCL) has been studied by several scholars in the past decades.However, these studies have mainly focused on the AC coils of the SCFCL, the DC excitation has seldom been mentioned.In this paper, the DC coil of SCFCL is studied as well as the rosy teacup dogwood influence of the novel structure of tightly-c
