Chemische Laboratorien: Funktion und Disposition

In this essay laboratories are dealt with as symbolic spaces that structure social relationships and ways of knowledge in chemistry. The spatial vicissitudes of the nineteenth‐century research laboratory reflect, and at the same time direct, the way chemical knowledge is being produced, transmitted, and perceived.     

一件罕见的明代“解银”伍拾两大锭

我们有幸收藏一件明代万历年间伍拾两解银大银锭。该银锭中间束腰,两头弧状,最长处127mm,最窄处61mm,厚25～35mm,重1855克(插四下右)。银锭底部密布蜂窝状孔眼,正面有数排手工錾刻的文字。由于该锭表面腐蚀氧化严重,至使锭面錾刻的文字有相当部分已模糊不清。经仔细辨认,尚可读出如下内容:“…县征解万历拾叁年……足银伍拾两……银匠…”。明代银锭,按用途分主要有解银、税银、镇库银及民间流通使用的碎银四种。税银是政府机构从民间征收田赋、丁役、盐税、土贡等费用,并将其折成银两上缴国库,但并不一定要全额送到京师,因各州县的财政库房…

The British road to war: Blair, Bush and the decision to invade Iraq

The British decision to go to war against Iraq with the United States has been widely criticized for being based on inaccurate and exaggerated assessments of the threat posed by Iraq. This article shows that the case for military action made by the British government was based on a measured analysis of the threat, on the conviction that the continued containment of Iraq through sanctions was not effective or morally acceptable, and that the human rights violations of the Iraqi regime were of a such a scale that they could no longer be tolerated. The article then assesses the judgements of the British government in the light of the information that has come to light since the war against Iraq in 2003.     

Der Scharlatan auf dem Rechtsweg — und was vielleicht zu seiner Umlenkung getan werden könnte

A number of recent allegations of scientific misconduct in Germany have led to judicial proceedings. Two examples are analyzed in depth, showing evidence for mutual incompatibilities between the legal system and the scientific system. In particular, it seems doubtful whether basic rules of good scientific practice are adequately and consistently taken into account by the courts when assessing the burden of proof. Strengths and weaknesses of some alternatives to judicial proceedings in such cases are discussed.     

声频应力波法检测土遗址加固用玻璃纤维锚杆锚固质量初探

土遗址锚杆锚固质量一直是土遗址加固工程中关注的重点问题。目前,土遗址领域均采用具有破坏性的拉拔试验对其进行检测。基于土遗址的文物属性,本研究尝试利用无损检测技术评价土遗址加固用玻璃纤维锚杆的锚固质量。通过锚杆无损检测仪与拉拔仪分别对甘肃省红沙堡遗址与永泰城址加固工程中的玻璃纤维锚杆锚固系统进行检测。比较实际测量杆长与仪器测量杆长结果,得出杆长指标可以判断无损检测仪所测结果的真实性。无损检测仪得出的检测波形衰减规律显著,对比相应锚杆的拉拔试验的评价结果,证实了声频应力波法在土遗址玻璃纤维锚杆锚固系统无损检测中的适用性。本研究结果将为评价土遗址加固用玻璃纤维锚杆锚固质量提供可靠的依据。
