Chiari malformation In Chiari malformation surgery, doctors remove a small section of bone at the back of your skull to make room for part of your brain (cerebellum) and relieve pressure on your brainstem, cerebellum and spinal cord.
Europium is a ductile metal with a hardness similar to that of lead. It crystallizes in a body-centered cubic lattice. Some properties of europium are strongly influenced by its half-filled electron shell.Europium has the second lowest melting point and the lowest density of all lanthanides.uropium is a ductile metal with a hardness similar to that of lead.

A solenoid is a cylindrical coil of wire whose diameter is small compared to its length. When an electric current flows through the wire the solenoid generates a magnetic field similar to that of a bar magnet. An electromagnet is a solenoid wound around a central iron core. The magnetic field generated by the coil of wire magnetizes the core, increasing the total magnetic field. An inductor is a coil of wire wound around a central core (iron or air), and is used to provide resistance to a DC current flowing through the wire.
