The 3D printing apparatus is usually attached to a multi-axis robotic arm and consists of a nozzle that deposits metal powder or wire on a surface and an energy source (laser, electron beam or plasma arc) that melts it, forming a solid object....
As astounding as it may still seem to many, Bell’s theorems do not prove nonlocality. Non separable multipartite objects exist classically, meaning w

A U.S. lab has successfully sparked a fusion reaction that released more energy than went into it. But there’s still a long way to go toward fusion as a clean energy source.
It is also worth noting that it is not an ideal method for the study of ischemia/reperfusion injury as the lesion created is resistant to the reintroduction of blood flow[25]. Molecular analysis of retinal ischemia The intensity of damage which occurs due to an ischemic injury is critically ...
Plasma Arc WeldingThis functions much like laser beam welding but is an arc welding process. It conducts an arc between a pointed tungsten electrode to the surface of the workpiece and the plasma is forced through a copper welding tip. Typically, no filler metal is added. The arc temperature...
