Laser-Induced Breakdown Spectroscopy (LIBS) was used in the examination of Bronze Age painted plaster samples from several sites in the Aegean and Eastern Mediterranean. The elemental content of paint materials was determined in most cases leading to the identification of the pigment used in agreement with data from analyses of the same samples with other established techniques. The analyses demonstrate that a virtually non-destructive technique such as LIBS provides sufficient data for the elemental characterisation of painting materials while in parallel has the capability for routine, rapid analysis of archaeological objects enabling the quick characterisation or screening of different types of artefacts. This certainly shows an important way forward in technological studies of fragile and scarce archaeological material. 相似文献

A recursive dynamic regional Computable General Equilibrium model is developed to assess the economic impacts of two Common Agricultural Policy (CAP) scenarios in six NUTS-3 (Nomenclature of Territorial Units for Statistics) (NUTS-1: major socio-economic regions, NUTS-2: basic regions for the application of regional policies, NUTS-3: small regions for specific diagnoses) regions of the European Union (EU). The main goal of the analysis is to assess the scenario effects (change in production, prices, income, employment) in the rural and urban parts of these regions as well as on the different sectors. The two scenarios analysed are related to a 30% reduction in Pillar 1 (market measures and direct support to farmers) support and the introduction of an EU-wide flat rate level of Pillar 1 support complemented by a 45% increase in Pillar 2 (Rural Development Policy) funds. Results show that the overall gross domestic product effects are not significant, due to the relatively low importance of both the agricultural sector and CAP spending in the regional economies. However, impacts on the agricultural sector are quite important and differ according to the nature of the policy shock. Also, the structural characteristics of each case study influence the rural–urban and sectoral spillovers, including impacts on region-specific agricultural activity. 相似文献
