Portable X-Ray Fluorescence (pXRF) apparatus of the last generation was tested to determine its potential for routine provenance determination of clay cuneiform tablets, which cannot be analyzed by “classical” intrusive methods. A group of tablets from Hattuša (Bo?azköy) and from el Amarna, which were previously provenanced using optical mineralogy (OM) and instrumental neutron activation analysis (INAA), was analyzed by pXRF and the results were used to establish the grouping according to their elemental concentrations. These groups were compared with the previous results retrieved by OM and INAA in order to confirm their validity. The results corroborate the high potential of the pXRF for non-destructive study of well-defined, ‘closed’ assemblages of clay-derived, delicate artifacts, such as cuneiform tablets, bullae, and fine-ware pottery. Consequently, a group of previously unexamined tablets from Hattuša was analyzed by pXRF and the results are discussed with implications on future research. 相似文献

Implementing culture-based development strategies is a recent trend in large and small cities all over Europe. The definition of culture and the objectives of cultural strategies are highly contested in the public debate. Analysing the newspaper debates on the establishment of the Cultiva foundation in Kristiansand, Norway, this article discusses how and why the discursive debate on the definition of culture creates different discursive positions in the public debate on culture-based development. In the different discourses on what these strategies should be, there are a number of antagonisms that contribute to defining the relationships and interfaces between the different discursive positions. The main lines of discursive conflict are between urban planners and/or policy-makers who follow a spatial logic that emphasises a comprehensive understanding of territorial planning and cultural workers and/or artists who follow a critical artistic creation logic that emphasises the values that exist in art and the potential of the cultural field for personal development, general education and social criticism. 相似文献

Tools are developed to predict damage to archaeological remains caused by the construction of line infrastructure on soft soil. They are based on numerical modelling and laboratory testing supported by X-ray microcomputed tomographic observations, and micromorphological analyses of thin sections. They have been validated for one-dimensional (1D) loading at two sites in the Netherlands where soil has been placed on top of organic layers rich in ecofacts and overlaying Pleistocene sands.Numerical prediction of the deformation of soft layers underneath an embankment remains a challenge for geo-technical engineers. Errors on surface settlement prediction reach ±15% of the measured total settlement.Laboratory observations show that vulnerable artefacts can get crushed when packed loosely in pure assemblies under 1D loading equivalent to less than 5 m of sand. Fragmentation is assimilated to loss of archaeological value as it compromises recovery during sieving. Embedment in a sandy or a very compressible organic matrix has a beneficial effect on the resistance of ecofacts. Embedded ecofacts can resist a load of more than 12 m of sand. Flattening and re-orientation of soft plant remains occur during 1D loading without microscopic damage of tissues. 相似文献

AbstractResearchers use a mathematical model to perform a counterfactual study of the 1854 Charge of the Light Brigade. They first calibrate the model with historical data so that it reproduces the actual charge's outcome. They then adjust the model to see how that outcome might have changed if the Heavy Brigade had joined the charge and/or if the charge had targeted the Russian forces on the heights instead of those in the valley. The results suggest that all the counterfactual attacks would have led to heavier British casualties. However, a charge by both brigades along the valley might plausibly have yielded a British victory. 相似文献
