The microstructure and chemical composition of blue cakes, found during the archaeological excavation of the Ayanis fortress (Eastern Anatolia, Turkey), have been investigated by means of scanning electron microscopy combined with energy dispersive spectrometry (SEM–EDS), X-ray diffraction (XRD), micro-Raman (μ-Raman) and optical microscopy (OM) techniques. The analysis of the Ayanis cakes has shown the presence of Egyptian blue (i.e. CuCaOSi4O10, cuprorivaite), as the major component, intermixed with minor amount of other phases such as partially reacted quartz grains, an adherent glass phase and copper oxides. Since the finding of Egyptian Blue in Turkey has been never reported so far, great attention has been paid to its characterisation. The micro-chemical and micro-structural investigations of the Ayanis cakes have allowed a further insight into the manufacturing process and into the sources of the starting materials. The results of the characterisation have revealed some significant differences with respect to Egyptian blue cakes found in Egypt and Mesopotamia, as for instance the absence of tin excluded the use of bronze scraps or filings in their preparation differently from those produced in Egypt and Mesopotamia. Furthermore, some peculiarities of Egyptian blue found in Ayanis, as the detection of zinc in the cakes, allow to put forward the hypothesis of a local production considering that a large part of the bronze artefacts found at the Ayanis fortress is characterised by the presence of zinc as minor alloying element. 相似文献

Cai, C., Clarke, D.J., Huang, D. & Nel, A., 2014. A new genus and species of Steninae from the late Eocene of France (Coleoptera, Staphylinidae). Alcheringa 38, 557–562. ISSN 0311-5518.A remarkable new genus and species of rove beetle, Eocenostenus fossilis gen. et sp. nov., is described and figured based on one well-preserved specimen from the late Eocene of Monteils (near Alès, Gard, France). Eocenostenus is definitively placed in the extant subfamily Steninae, based on the combination of dense and coarse body punctation, globular and protruding eyes, exposed and closely spaced antennal insertions on the vertex, and six visible abdominal terga. Eocenostenus differs from the two extant stenine genera Stenus and Dianous most notably in the structure of the prothorax, which is strongly transverse and with unusual anterolateral projections, and in the anteriorly placed antennal insertions. This new discovery highlights the palaeodiversity of a genus-poor subfamily and suggests that the early diversification of Steninae is probably complicated.Chenyang Cai [caichenyang1988@163. com] and Diying Huang [dyhuang@nigpas. ac. cn], State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, 39 East Beijing Rd., Nanjing 210008, PR China; Dave J Clarke [dclarke@fieldmuseum. org], Integrative Research Center, Field Museum of Natural History, 1400 S Lake Shore Drive, Chicago, IL 60605, USA; and André Nel [anel@mnhn. fr], Muséum National d’Histoire Naturelle, Institut de Systématique, Evolution, Biodiversité, ISYEB, UMR 7205 CNRS UPMC EPHE, CP50, 45 rue Buffon, F-75005 Paris, France.

NEL, A., LAPEYRIE, J. & GARROUSTE, R. May 6 2019. The first European representative of the South American family Xenopteraidae (Insecta: Megasecoptera) discovered in the Guadalupian of Lodève (France). Alcheringa 43, 436–440. ISSN 0311-5518.A new genus, Sinitshenkovae gen. nov., is described, comprising the Carboniferous species Sinitshenkovae hueneckeni (Pinto & Pinto de Ornellas, 1978) comb. nov. from South America and new Guadalupian species S. gallica sp. nov. from France. These two species are attributed to the Paleozoic South American family Xenopteraidae, a previously monospecific family only containing Xenoptera riojaensis Pinto, 1986. Sinitshenkovae gallica sp. nov. is therefore the youngest representative of this family and the only record outside South America, which suggests that our current knowledge of the palaeobiogeography of Permian and Carboniferous insects remains incomplete.André Nel [anel@mnhn. fr] and Romain Garrouste [garroust@mnhn. fr], Institut Systématique Evolution Biodiversité (ISYEB), Muséum national d’Histoire naturelle, CNRS, Sorbonne Université, EPHE, 57 rue Cuvier, CP 50, 75005 Paris, France; Jean Lapeyrie [jean. lapeyrie@orange. fr], Corniche de Fontbonne, F-34700 Lodève, France. 相似文献

In the region of Chapada dos Guimarães, Western Brazil, planters relied heavily on slave labor during the eighteenth and nineteenth centuries. In this article, we examine the locally produced pottery found on slaves contexts in five rural sites of this region. Based in data from probate inventories and the pottery decorative variability we suggest that slaves used decorated pottery to express cultural and social differences. 相似文献

We analyze the firm-level labor productivity growth returns of social capital—defined as a synthetic measure of “generalized trust,” “active participation,” and “social norms”—using a large sample of manufacturing firms in France, Germany, Italy, Portugal, and Spain. We find that firms' labor productivity growth is higher in areas with a better social capital endowment. The positive returns of social capital are, nevertheless, unevenly distributed across firms, with smaller, less productive, less capital-endowed, and low-tech firms benefitting the most from operating in strong social capital ecosystems. 相似文献

Cette micro‐analyse des migrations italiennes vers Manosque permet de remettre en question l'historiographie traditionnelle de l'immigration qui postule un déracinement, la solitude et la marginalité des migrants. Cette article montre au contraire un processus d'inclusion dont la rupture eventuelle avec les communautés d'origine démontre le succès. Une migration de rupture ne signifie pas que les relations avec la patrie d'origine se distende totalement. Des liens subsistent comme le démontrent les legs et les testaments. Sur deux siècles il y a une continuité migratoire et des réseaux persistant d'intégration. 相似文献
