Additive manufacturing technologies are in the process of establishing themselves as an alternative production technology to conventional manufacturing such as casting or milling.Especially laser additive manufacturing (LAM) enables the production of metallic parts with mechanical properties comparable to conventionally manufactured components.Due
BackgroundPrimary immunodeficiencies are heritable defects in immune system function.Antibody deficiency is the most common form of primary immunodeficiency in humans, can be caused by abnormalities in both the development and activation of B cells, and may result from B-cell-intrinsic defects or defective responses by other cells relevant to humor
According to operational experience of power systems, the outdoor insulation strength can be reduced due to the effect of rain.Till now, little work has been done to investigate the flashover performance of air gapped arresters under rain conditions.Therefore, Other Dolls in this paper, experiments were carried out and the AC flashover performance
