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 use of crucibles in the Iron Age remains very similar to that of the Bronze Age with copper and tin smelting was being used to produce bronze. The Iron Age crucible designs remain the same as the Bronze Age. The Roman period shows technical innovations, with crucibles for new methods used to produce new alloys.
