Microanalytical identification of Pb-Sb-Sn yellow pigment in historical European paintings and its differentiation from lead tin and Naples yellows

The work is focused on identification of lead tin yellow types I and II, Naples yellow, and also on discrimination of a less common, distinct yellow pigment, the ternary Pb-Sb-Sn oxide.The knowledge about all those Pb-based yellows was in fact forgotten after introduction of modern synthetic yellows in 19th century. As late as in the last decade of the 20th century, the existence of Pb-Sb-Sn yellow and its production have been rediscovered, and only then it has been identified in colour layer of artworks.Pb-Sb-Sn yellow has recently been identified in colour layer of 17th century Italian paintings by Sandalinas and Ruiz-Moreno [C. Sandalinas, S. Ruiz-Moreno, Lead tin-antimony yellow, historical manufacture, molecular characterization and identification in seventeenth-century Italian paintings, Stud. Conserv. 49 (2003) 41–52], and here we report the finding of this pigment in Mid-European painting of the 18th and 19th centuries. Lead tin yellows, lead antimony yellow (Naples yellow), and lead antimony tin yellow were synthesized in laboratory following historical recipes, their colour was analyzed, and their structure was confirmed to provide a basis for their routine identification in microsamples of artworks by X-ray microdiffraction. Unequivocal identification of Pb-based yellows could help in authentication of traditional European paintings, because their use was temporally and also geographically specific. Combination of elemental microanalysis (X-ray fluorescence electron microanalysis) and X-ray powder microdiffraction were found very efficient in the microanalysis of colour layers of artworks with Pb-based yellows and their unequivocal identification.     

Are boys that bad? Gender gaps in measured skills,grades and aspirations in Czech elementary schools

This article examines gender gaps in academic performance (grades in mathematics and reading) between boys and girls of ninth-grade elementary schools in the Czech Republic. Our analysis is based on 2003 data from the Programme for International Student Assessment, encompassing the academic performance and family background of ninth-grade pupils. Similar to research on other countries, we find that girls strongly outperform boys in grades in Czech language, but that this gender gap is not explained by measured ability in reading nor on family background or student attributes. We also find gender bias in mathematics grades, after controlling for measured ability and other factors. Girls are also substantially more likely than boys to apply to secondary grammar schools, as well as aspire to a college education, even after controlling for measured ability. We put forward a number of theoretical perspectives that shed light on the possible causes of these empirical findings.

访谈录：专利侵权诉论策略和技巧

在知识产权保护中，专利保护是一种比较强的保护手段。对于技术含量高的产品，企业一般会选择用专利保护。然而，当遇到专利侵权时，由于专利涉及复杂的技术问题，打这类官司最为费时费力。面对有时长达数年的诉讼，一些外国公司甚至选择了离开中国市场。英国Strix公司是留下来的大多数外国公司之一，它是全球最大的小型自动温控器制造商，在中国拥有近100件专利。
