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.

Large amounts of vanadium ions are found in a few organisms, possibly as a toxin. The oxide and some other salts of vanadium have moderate toxicity. Particularly in the ocean, vanadium is used by some life forms as an active center of enzymes, such as the vanadium bromoperoxidase of some ocean algae.anadium occurs naturally in about 65 different minerals and in fossil fuel deposits. It is produced in China and Russia from steel smelter slag; other countries produce it either from the flue dust of heavy oil, or as a byproduct of uranium mining.
