In the Iberian Peninsula, the copper metallurgy from the Chalcolithic to the Middle Bronze Age (MBA) was mostly characterized by low arsenic contents. A collection of 53 MBA artefacts from southern Portugal was analysed by micro‐EDXRF, optical microscopy, SEM–EDS and Vickers to investigate the metal composition and manufacture. No technological distinction was found between artefacts from domestic and funerary contexts, which were radiocarbon‐dated to 2000–1500 cal bc . The arsenic contents of almost 100 MBA artefacts from this region, including the above‐mentioned set, have a Gaussian distribution with a high average (3.9 wt% As). Possible explanations are discussed for this distinctive metallurgy at the south‐western end of the Iberian Peninsula. 相似文献

Excavations in the arid regions of Egypt provide insight into the many types and uses of mudbrick architecture. Upon exposure the inherently unstable building material decays rapidly, resulting in severe loss or complete destruction of once well-preserved buildings. The preservation of mudbrick structures is relatively complicated and expensive. Research has focused on the circumstances that enable preservation and the influence of climate and weather over time. Conservation treatments should address these two processes as soon as possible after exposure of the structures. Our assessment of a range of conservation methods leads to the conclusion that reburial is among the least objectionable method of preservation, despite its drawback of returning the excavated buildings to a situation where they are invisible to both researchers and the public. 相似文献

ABSTRACTAlthough in terms of their bilateral relations the ‘traditional friendship’ between Great Britain and Austria-Hungary was no mere phrase, in general political terms British policy in the last decade before the War was characterised by Grey's determination to cultivate the ententes with France and Russia and to do nothing to upset that division of Europe into two balancing groups (with Austria-Hungary firmly in the German camp) which he saw as the best guarantee of peace. Even though the Austrians gradually recovered from the shock of the Bosnian Crisis, in which Grey had come forward against them as Russia's chief supporter, and though the British for their part came to see in Austria-Hungary a useful element of stability in the Near East, Grey's attempts to uphold the unity of the Concert in the Balkan Wars were in the end vitiated by his overriding concern to avoid offending his Entente partners. Indeed, as the crisis deepened in the last year of peace, he took refuge in an increasingly abstentionist attitude, the objective effect of which - and herein, it is here argued, lies Grey's responsibility - was to intensify Vienna's desperation and loss of faith in the Concert that soon proved fatal to peace. 相似文献

This article explored the possible role of a “mentor” and is based on theoretical pointers from the Old Testament figures. Throughout the article mentoring was explored according to the approach of (T. Van der Walt:2007, 309). The background and narratives of Old Testament figures such as Abraham, Isaac, Jacob, Joseph, Moses, Joshua, Elijah, Elisha, David and Solomon were investigated. They were chosen for their leadership and guidance. Abraham and Jacob were the patriarchs of the Bible. Moses was and is still recognized as the greatest leader in history. Elijah and David were great and mighty prophets and kings. These narratives linked with the theory about mentoring and the significance thereof in today’s society of a father as mentor in a home. 相似文献

Shortly following Canada's controversial adoption of nuclear weapon roles in NORAD and NATO in 1963, the focus of nuclear debates shifted to the potential impact on Canadian and international security of the construction of US anti-ballistic missile (ABM) systems. This article expands the focus of scholarship on the ABM issue from the political and policy-making settings to include members of the attentive elite and the news media, and finds these groups deeply divided between liberal and conservative internationalists. On the one hand, supporters of liberal internationalism believed that AMB systems would destabilise the international security environment and ultimately increase the likelihood of nuclear war. Conservative internationalists took the opposite position, arguing that the systems represented a necessary addition to the Western nuclear deterrent and would make nuclear war less likely. In other words, the ABM debate exposed deep divisions in Canadian society between those who preferred diplomatic and multilateral versus military means of achieving middle power goals in the international system. 相似文献

The Royal Artillery Factory of Seville in Spain originated from pre‐existing private bronze foundries dating from the 16th century. The paper analyses the stratigraphy of wall cladding in the areas traditionally known as the ‘Old Foundry’ and the ‘New Foundry’, through its characterization by optical microscopy, scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX), micro‐X‐ray fluorescence (μ‐XRF) and micro‐X‐ray diffraction (μ‐XRD), in order to analyse the metal deposits that have accumulated since the 17th century. The data obtained allowed the verification of the available historiographical information and the location of the original bronze smelting furnaces. The analysis of patinas deposited on the overlapping layers of lime also confirmed that neither the raw materials nor the composition of the alloys used presented any substantial changes. 相似文献

The rapid expansion of non‐ferrous metallurgy in the late Middle Ages (14th–15th centuries) enhanced ore demand, which was supported by mining intensification. Metallurgical workshops developed various supply strategies based on geological, political and economic constraints. This is particularly true for the Pyrenean multi‐metals workshop of Castel‐Minier (Ariège, France), where recent excavations unearthed an exceptional corpus of non‐ferrous ores. A specific analytical methodology combining micro‐Raman spectroscopy and environmental scanning electron microscopy with energy dispersive X‐ray (ESEM‐EDX) was set up to study these artefacts. This composite methodology permitted the fast characterization of both mineral and gangue as well as a discussion of their economic potential. Ores identified were compared with ancient mines in neighbouring mining districts in order to sketch a geography of the mineral resources available to medieval metallurgists. Moreover, a chrono‐stratigraphic study of ore distribution in Castel‐Minier revealed the supply strategies, technological choices as well as spatializing of copper and lead metallurgies. 相似文献
