探讨EOS染色剂对血迹DNA检验的影响

目的探讨被EOS染色剂处理后的血迹进行DNA检验的初步方法。方法制备EOS染色剂处理的血迹样本，分别采取纯水擦拭、75％酒精擦拭，或手术刀刮取血痕浸泡于纯水中、759／5酒精中，然后提取DNA进行下一步检测。结果采用刀刮取血痕浸泡于759／6酒精中，提取的DNA检测结果较好。结论初步实验显示，经EOS染色剂处理过的血迹，可参考刀刮取血迹置于75％酒精浸泡后提取DNA做下一步检测。     

Eu merger control and the compatibility test:a review of recent developments

The compatibility test contained in Article 2 of the Merger Control Regulation (MCR) is at the very heart of EU merger control, for it determines whether a concentration with a community dimension is deemed compatible or incompatible with the common market. Incompatibility can lead to prohibition of a concentration, although this is rare. The paper reviews the recent developments to the conditions of the test itself as well as the analytical methods employed to determine compatibility. Concerning the former, the new foreseeable dominance interpretation, put forward by the European Commission and made law by the Court of First Instance (CFI), is explored. This new variant of the dominance condition is important on its own right but it is also of major interest because of the explicit legal requirement placed on the Commission to assess the future likelihood of abusive behaviour by the merging parties in its prospective analysis. This is not the case with the original dominance compatibility condition. The unexpected but important clarification by the CFI of the notion of substantial part of the common market, as contained in the express wording of the compatibility test, is also commented upon. Concerning the determination of compatibility, the Commission's controversial employment in certain conglomerate concentrations of the range effects of competitive harm theory is examined, as is the need to take cognisance of merger specific efficiencies when determining if a merger increases societal welfare. The EU is making progress toward such an efficiencies assessment as part of the compatibility determination. EU merger control – and hence the compatibility test – do not exist in a vacuum. The EU has played a major role in shaping the new multilateral architecture and its goal of increasing international convergence in competition matters. This in turn has led the EU to rethink the nature of the compatibility test. For example, it has sought to evaluate the dominance condition of the compatibility test with the substantial lessening of competition (SLC) approach used by some other regulators, like the US. The paper concludes by looking at a fundamental issue that has arisen from recent CFI judgements and the GE/Honeywell merger: the competence of the Commission, or more accurately the Merger Task Force (MTF), to carry out the compatibility determination. Proposals are outlined so as to ensure that the Commission's prospective analysis in a concentration case meets the requisite legal standard. It is essential for this standard to be met if EU merger control is to remain credible. This revised version was published online in July 2006 with corrections to the Cover Date.     

踹门足迹的发现、提取与分析检验

踹门足迹是指犯罪嫌疑人用足撞击门 ,破坏锁体或门 ,使门锁分离或门板与门框分离而遗留在门面上的足迹。由于形成踹门足迹的承痕落体、作用力的大小与方向和正常步行足迹相比比较特殊 ,因此 ,它们在特征利用、分析方法和检验重点上有较大区别。
