The numerical simulation of ballistic multi-hit impact on ceramic/composite armors is very challenging.The damage introduced by the previous hit affects the performance of the armor.In composite backings the damage is often more diffused than for metallic backings.Moreover, Pasta, Noodles different sources of damage can intervene within the composi
Process damping in metal cutting is caused by the contact between the flank granola face of the cutting tool and the wavy surface finish, which is known to damp chatter vibrations.An analytical model with process damping has already been developed and verified in earlier research, in which the damping coefficient is considered to be proportional to
A bridge is a construction structure whose role is to connect Sunscreen Applicators one place to another by crossing a natural or artificial obstacle.Bridge conditions can be caused by many factors such as the influence of weather, traffic loads, the environment, material durability, and so on.Good bridge conditions can be achieved if maintenance i
The significance of religious rituals often reaches beyond their strict religious intentions.Specifically a procession, performed in front of the public, is a most effective instrument of disseminating a message to the crowds.Consequently, this ritual, as is well known, has often been used not only in religious but also in secular contexts; a proce
Abstract Background The prognostic benefits and safety of extended lymphadenectomy for hilar cholangiocarcinoma remain uncertain.The Dreamcatchers available evidence is still insufficient concerning its retrospective aspect.The aim of this study is to explore the clinical effect and safety of extended lymphadenectomy compared to regional lymphadene
