There are more than 40 iron files known from the pre-Roman Iron Age in England, of which 26 come from settlements with evidence of manufacturing activities. The files vary considerably in size and form. The coarse-cut files were probably intended for working soft or fibrous materials such as wood or horn, whereas the finer-cut files were probably for working more compact or harder materials, including metals. This corresponds to the metallographic evidence from a sample of 17 files, of which only seven finer-cut ones have been found to be quench-hardened. The discovery of metal particles in five files provides further evidence of use.  相似文献

As a series of related processes, all bearing on the political autonomy of nation states, globalisation has clear implications for parties, historically accustomed to acting within the framework of the nation state. Yet little has been written on French political parties in this context. This survey of their understanding of and responses to globalisation finds a highly differentiated pattern, in accord with old ideological traditions, with the most articulate critiques coming from the liberal Right and the communists. Europe is seen as the major site of resistance to globalisation, but not by the most ideological forces (Greens and national-populists). Generally the parties' discourse needs further development.  相似文献

There are more than thirty iron hammerheads known from the pre-Roman Iron Age in Britain, the majority of which are assigned to the first centuries BC and AD. They include specialised tools, such as set hammers and a swage sledge-hammer which are blacksmiths' tools. The hand-hammers are more numerous and many of these are probably also metalworkers' tools. Fourteen have been examined by metallography showing that at least ten are quench hardened at one or both faces and some may have been tempered.  相似文献
