Modern obelisks, big and small, are found all over the world and the U.S. from the Washington Monument, to war memorials, to the grave markers of presidents (Washington, Jefferson, and Lincoln's tombs all include obelisk memorials).
Vanadium was named after the Scandinavian goddess of beauty, youth, and luster. It is a controversy as to whether vanadium is an essential trace mineral in human nutrition. Although it has been suggested to function in hormone, cholesterol, and blood sugar metabolism, no specific deficiency signs have been reported.anadium was named after the Scandinavian goddess of beauty, youth, and luster.

About 80% of the vanadium produced is used as a steel additive. Vanadium-steel alloys are very tough and are used for armour plate, axles, tools, piston rods and crankshafts. Less than 1% of vanadium, and as little chromium, makes steel shock resistant and vibration resistant. Vanadium alloys are used in nuclear reactors because of vanadiumâs low neutron-absorbing properties. Vanadium(V) oxide is used as a pigment for ceramics and glass, as a catalyst and in producing superconducting magnets.
