Application of magnetic susceptibility on polished stone tools from Western Hungary and the Eastern part of the Czech Republic (Central Europe)

A non-destructive method – magnetic susceptibility (MS, κ) measurement – was used to characterize about 360 Neolithic, Copper and Bronze age polished stone tools of the Miháldy collection (Laczkó Dezső Museum, Veszprém, Hungary), composed of artefacts from three Neolithic (Moravian Painted Ware) workshops around a source of greenschist at Želešice near Brno (Moravia, Czech Republic) and semifinished artefacts from workshops at Neolithic mines in the Jizerské hory Mts. (Bohemia, Czech Republic); in addition, rock reference samples collected from the possible provenance areas and rock outcrops in the Czech Republic, Slovakia and Hungary were analysed as comparative material with the same method. We elaborated a model experience to control the thickness correction factor (TCF) following Williams-Thorpe et al. (2000).Among various stone raw materials of polished artefacts we found basaltic rocks and greenschists-metabasites as the most common.     

中华民国三十四年中央银行纸币印刷颜料无损研究

法币在中国货币史特别是近代货币史上有着重要地位。1935年11月至1948年8月间,先后发行了15种从"壹分"到"壹萬圆"不同面额的法币,由中外十六家不同印刷公司承印,版别多达百余种。本研究利用超景深三维视频显微镜、激光显微共聚焦拉曼光谱仪和便携式X射线荧光光谱仪,对11枚1945年(中华民国三十四年)中央银行发行的壹仟圆法币的印刷颜料进行了无损研究。结果表明,红色部分(印章、冠字号、纹饰等)普遍使用了有机合成染料系列颜料红PR,而蓝色、绿色、棕色部分普遍使用了普鲁士蓝、铅铬黄和炭黑等颜料进行调配呈色。这些信息能够为纸币类文物的鉴别、保护修复以及相关研究提供依据。     

CT and micro‐CT analysis of a case of Paget's disease (osteitis deformans) in the Grant skeletal collection

This paper presents a case study in which Paget's disease of bone is differentially diagnosed in an individual from the Grant skeletal collection using non‐destructive computed tomography (CT) and micro‐computed tomography (micro‐CT) analyses of the pubis, in addition to plain film radiography and macroscopic examination. In archaeological and modern osteological samples diagnosis frequently relies on macroscopic examination, plain film radiography and histological examination of bone samples. CT and micro‐CT modalities provide researchers with a non‐destructive view of the internal structure of bone unhampered by the superimposition that is characteristic of plain film radiographs. Given the importance of the increased cortical and trabecular thickness in the differential diagnosis of Paget's disease, these techniques are ideal means by which to non‐destructively examine culturally‐sensitive and scientifically‐valuable human remains for signs of Paget's disease of bone.
