It is of some advantages for non-destructive testing surface and internal flaws using EC/EMA dual probe. The fusion detection principle of EMA/EC is emulated by finite element method. Aimed to EC, the current eddy field distribution focused on skin and coil impedance variation induced by eddy field is studied by theory and experiment method, and aimed to EMAT, the propagation characteristics of the...
Bacteria in nature often suffer sudden stresses, such as ultraviolet (UV) irradiation, nutrient deprivation, and chemotoxins that would cause DNA damage and DNA replication failure, which in turn trigger SOS response. According to the strength and duration of the stress, the SOS system not only repairs DNA damage but also induces mutagenesis, so as to adapt to the changing environment. The key proteins...
