Mingguo Zhai,Xiyan ZhuDM, in addition to erosion of workpiece material, some amount of tool removal also occurs. Other than machining, EDM is also used for surface coating purposes. The electrode material is coated on the work surface during the electric discharge coating (EDC) process. In powder mixed EDM (PMEDM), some

Perhaps the most satisfactory explanation is to call attention to the overlapping heterogeneity of the lipoprotein classes and to emphasize the interdependence of all the human lipoproteins. The intensive study of patients with abetalipoproteinemia (

Various investigations, involving surface spectroscopy, electron microscopy, ion scattering, direct radiotracer measurements, and Monte Carlo simulations have contributed considerably to our understanding of the diffusion behavior.
