Deformation Behavior under Tension with Pulse Current of Ultrafine-Grain and Coarse-Grain CP Titanium.

The problem of the real existence of the electroplastic effect during deformation of metallic materials of different nature is still relevant. At the same time, the influence of structure refinement is not considered enough. In this work, the deformation behavior of ultrafine-grained (UFG) titanium Grade 4 is compared with that of coarse-grained (CG) titanium under tension with pulse current of the low duty cycle.

[Selection of the method of ureterotomy in ureteral calculi].

A comparative assessment of longitudinal and transverse ureterotomies in experiments and clinic has shown the transverse ureterotomy to be a more physiological method. The observation of the patients in dynamics has revealed an earlier and more valuable recovery of the ureter functioning than after longitudinal ureterotomy.
