The purpose of this review is to investigate the clinical utility of functional brain imaging in patients with AD, brain tumours, epilepsy, MS, or Parkinsonâs disease. Because the focus is on clinical utility, the added clinical information that would be provided by Level 1 studies (i.e., studies of technical feasibility) is limited.
The Iron Industry. In the centuries before the Industrial Revolution, the quality of iron and the process of refining it had changed little in Great Britain. Iron had been used for agricultural tools, chains, locks, bolts, nails, horse stirrups, scythes, sickles, and anchors.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel.98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is more integral to the global economy than any other commodity, except perhaps oil.he ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH) , 62.9% Fe), limonite (FeO(OH).n(H2O)) or siderite (FeCO3, 48.2% Fe).
