家兔死后眼玻璃体液镁,铁含量与PMI关系的研究 总被引:5,自引:0,他引:5
目的寻找一种精确推定PMI的方法。方法应用电感耦合等离子体质谱(ICP-MS),检测家兔死后96h内眼玻璃体液镁、铁元素含量,探讨其与PMI的相关性。结果家兔死后0~48h眼玻璃体液镁元素含量与PMI显著相关,6~48h铁元素含量与PMI显著相关,其二项式回归方程分别为y=0.0738x2+0.6997x+11.45(R2=0.9119)、y=0.0411x2-0.3148x+1.4113(R2=0.9594)。结论家兔死后眼玻璃体液Mg、Fe含量变化可作为推定48h内PMI的参考指标之一。 相似文献

In many criminal and civil cases, some questioned documents are written with iron gall ink. Determining the date when an iron gall ink entry was written can be important to assess the authenticity of a document. A dissolution‐diffusion method was successfully employed to draw aging curves of iron gall ink entries stored in controlled conditions over 40 months. Calibration curves were created to indicate the relationship between the average dissolution‐diffusion rate of ink components and the age of ink entries stored under natural aging conditions. As preliminary findings of this study, the mixed solution of dimethyl formamide (DMF) and anhydrous ethanol was suitable to dissolve the dye of iron gall ink strokes made at different time. It was also determined that brands of iron gall inks, types of paper, and thickness of iron gall ink strokes had varying impacts on estimating the dates of iron gall ink strokes. 相似文献

AbstractThis paper describes two Norwegian governance networks. While both address questions about land-use and transport, the ways in which they are democratically anchored differ. Starting out from goals set for climate-friendly transport, linkages between democratic anchorage and network effectiveness are discussed. In some ways the network with the lowest stakeholder involvement, and therefore the smallest network structure, has come furthest – measures are implemented quickly and extensive resources are used to improve public transport. The other network does not have the same implementation rate or resource-use, but has shown strong efforts to mobilise and coordinate a wide set of actors. Both approaches involve important elements for reducing emissions from transport, specifically the effectiveness and toughness of one and the broader mobilisation of the other. Applying a wide set of criteria to evaluate network performance, the paper discusses the advantages and disadvantages of the two network structures. 相似文献

The Czech–German borderlands are an archetypal European border region. They evoke not only Cold War histories, but also shelter layers of European memories of the ethnic reshaping of early post-war Europe. By means of life story interviews with German speakers of the border region, this article analyzes the symbolic meaning of and the individual dealing with the local Iron Curtain. It will shed light on the biographical and narrative interconnectedness of experiences of ethnic cleansing in the early post-war period and retrospective perceptions of the Iron Curtain in these borderlands. In particular, it inquires whether and to what extent the local Iron Curtain intensified fractures caused by the region's post-and pre-war attempts to halt the multiethnic composition of the border communities. The article suggests that the local Czech–German Iron Curtain would have never endured as strongly if the border communities' common identity had not already been severely damaged in the course of the region's traumatic history and forced population transfers. 相似文献

ABSTRACTUsing Ropa?i Manor as an example, this article analyzes evidence of iron production and ironworking in Vidzeme in the sixteenth and seventeenth centuries, characterizing the first results from an interdisciplinary study of this previously almost unresearched field. Content analysis of written sources in conjunction with linguistic analysis, archeological fieldwork, remote sensing and geophysics, paleobotany, and analysis of forest growing conditions illuminate aspects of economic life linked to or hypothetically relating to iron supply and processing, namely iron importation and circulation, craft activities, and charcoal production far exceeding local needs. Local iron production is not proven; neither is there evidence excluding it. 相似文献

ABSTRACTThorleifsson examines the ways in which violent imaginaries of Sweden have been discursively constructed and used by populist radical-right (PRR) parties and actors in contemporary Europe. Based on multisited fieldwork among politicians and supporters of the United Kingdom Independence Party (UKIP) and the Hungarian Jobbik party, this article demonstrates how individual acts of violence are ‘transvaluated’ into violent imaginaries of migrants from Muslim-majority lands. What Thorleifsson terms ‘the Swedish dystopia’ not only entails a message of alarm and warning. PRR actors also use the trope of the Swedish dystopia in their call for action against Muslim migrants and minorities who, they claim, pose an ethnoreligious threat to national identity, security and even (Judaeo)-Christian civilization as a whole. 相似文献

Since the economic bubble burst, Japan has been in a long-term recession. To stimulate the economy, improve the infrastructure and increase employment, the Japanese Government injected a substantial amount of money into public works in the 1990s. However, these public investments had limited utility but incurred huge debts. These public investments have become a controversial issue. The Japanese Government could not but promote many reforms concerning public investments. This paper focuses on Japan's case and introduces the debates on public investments. 相似文献
