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.
Except for a few, where in aluminum is used to give light weight to the body. But the main frame work and other parts like pistons, wires, wheel bearings are made of iron. Grey cast iron is used in making engine piston cylinder cases, gear boxes and other tools. While white cast iron is used to make bearings. Again here iron is preferred for its toughness, ability to withstand high temperature of engine etc.
