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.
The iron industry began in forested areas since trees were necessary to make the fuel, charcoal. It was cheaper to move iron to the iron works than to move the vast amounts of charcoal needed. When ironworking and shipbuilding caused the forests to shrink rapidly, it became necessary to search for an alternative fuel.
