    Metallographic investigation of Early Bronze Age armbands from Western Switzerland (ca. 2200–1500 BC): new highlights about early manufacturing processes

    No full text
    The Valaisan-type armband (a specific type of bracelet) is a typical metallurgical production from the western area of Switzerland belonging to the classic phase of the Aare-Rhone group (BzA2a, ca. 2000-1800 BC). This investigation aims to (i) characterize the metal composition, (ii) reconstruct the thermomechanical treatments applied during the manufacturing process, and (iii) gather information on the possible exploitation of the local ores coupling metallography and chemical analysis. The results show that each armband is manufactured from a hammered sheet of copper-based alloy, containing either tin (up to 3.0 wt.%) or a combination of antimony, nickel, and silver. In several cases, it is assumed that minor elements are already part of the original ore, suggesting a conscious selection of copper veins. In other armbands, a direct addition ofcassiterite(SnO2) to the copper matrix is hypothesized based on the material composition and features of the inclusions. Microstructural features are coherent with a procedure that combines mechanical deformation (with a total deformation degree between 70 and 76%), annealing, and quenching, coherently with more recent productions (Late Bronze Age). The analysis of inclusions, rarely performed during metallographic investigations, provides precious evidences on thermal treatments applied during the manufacturing process and shows that annealing was carried out at low temperatures

    Are tin oxides inclusions in early archaeological bronzes a marker of metal recycling?

    Bronze artifacts from Early Bronze Age in Europe often contain white inclusions in the metallic matrix, that are identified as tin oxides (SnO 2 or Cassiterite). These inclusions are interpreted as un-smelted residues coming from the copper ore and are generally mixed with more complex oxidized inclusions, which contain sulfur, antimony, arsenic, silver, nickel and cobalt. The nature, shape and distribution of these partially smelted tin inclusions give information on the alloying process. Depending on the technological context and the geographical areas, the presence of such inclusions might indicate that the material has been produced by selecting and supplementing of raw materials containing SnO 2 (e.g. co-smelting). In order to understand the role of tin oxide inclusions in the production of bronzes and possible recycling procedures, a crosscutting investigation has been carried out, based on experimental researches. The results show that tin oxides do not completely reduce after four re-melting cycles (recycling) and such a fact is deeply related to the oxygen availability and the dwell time that influences the kinetics of the reaction

    CityLog - Sustainability and efficiency of city logistics: The M-BBX (Modular BentoBox System)

    This paper presents some of the results of CityLog, a European Union project approved in the context of the 7th Framework Programme that is still ongoing and will terminate at the end of 2012. The project is intended to increase the sustainability and the efficiency of urban delivery of goods through an adaptive and integrated mission management and innovative vehicle solutions. Three partners of the CityLog consortium were in charge of the design and realization of a new container concept which had to be adapted to the associated innovative vehicles solutions for load units' handling operation. © 2011 IEEE

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
