Titanium alloys used for rotating parts of aeroplanes must meet the strict standards of quality, so that it is required to demonstrate that electron beam melting is capable of producing defects-free ingots.However, complete elimination by dissolution of here low density inclusions (LDI) having high nitrogen content would be difficult, so that a new
Reconnections of spatiotemporal optical vortices have been shown to occur between line vortices.Here, we show that reconnections also occur between spatiotemporal loop click here vortices in optical waves.As optical loop vortices propagate in a media with spatial diffraction and material group velocity dispersion, unique reconnections occur.The bir
To study the influence of different liner structures and materials (copper, steel, and tungsten) on the forming characteristics of multiple explosively formed projectile (MEFP) with integrated liner and shell designs, three types of liners with different structures were designed.LS-DYNA was used for numerical simulation, and the results show that t
The Klippel-Trenaunay syndrome, first reported eeboo coupons in 1910, is a triad of cutaneous hemangioma, varicose veins, and soft tissue or bony hypertrophy.The varicosities are extensive involving the tributaries of the greater or lesser saphenous systems.Arteriogram are normal with no evidence of arteriovenous fistulas.Multiple ligation and stri
