DNA evidence frequently plays an important role in criminal investigations and in some cases may be the only means of convicting a suspect. The constant improvement of DNA analysis techniques affords the individualization of minute amounts of DNA, aggravating the risk of contamination artifacts. In our study, we investigated the prevalence of DNA contamination in the autopsy facilities of the Institutes of Legal Medicine in Essen and Kiel (Germany). Using DNA-free swabs, we took samples from instruments used during autopsy and autopsy tables. Surfaces and instruments were routinely cleaned before sampling. Swabs were subjected to different PCRs to quantify the total amount of DNA and to amplify individual specific STR-markers. In most samples, alleles that could be linked to bodies that had been autopsied before were found. Furthermore, we could show that a DNA transfer from the autopsy table to a body was detectable in four out of six cases investigated. The interpretation of DNA typing results may thus be severely complicated. To avoid DNA contamination, we tried out different cleaning methods, of which only a bleach containing cleaner showed sufficient results.  相似文献

In November 1986 a Lebanese newspaper revealed the secret arms-for-hostages deal between Tehran and Washington that subsequently became known as the Iran-Contra-Affair. The newspaper had been tipped off by friends of the Iranian radical Mehdi Hashemi who had been arrested shortly before in Iran. This article explores the link between the arrest of the ardent supporter of the then deputy leader Hossein-Ali Montazeri and the secret talks with the US government. The article will show that his arrest was not only an attempt of the then dominant faction around Ali Akbar Hashemi Rafsanjani to bring the future leader Montazeri under its control, but also an attempt to eliminate a rival actor opposing the rapprochement with the USA and threatening to disrupt the arms-for-hostages deal.  相似文献

What are the core services of start-up incubators, and how can the be managed best? We use five incubator archetypes (university, regional business, company-internal, independent commercial, and virtual incubators) to identify key services and describe their implementation. Case-research was conducted on 10 incubators (from an estimated total of 50) in Italy. We concluded that differences in competitive scope (industry, geography, and segment focus) and differences in strategic objectives (profit versus non-for-profit) influence the nature, quality and implementation of incubation services and the way they are managed.  相似文献

Legal context: Despite the commercial importance of licences, the Regulation40/94 contains relatively few provisions on licences. As faras these refer to licences granted to CTMs or their recordalat OHIM, they are beyond the scope of the article, which dealswith the case law emanating from OHIM in inter partes proceedings,where licences have played a role. Key points: This article considers the legal requirements licensees mustmeet when filing opposition and cancellation proceedings beforeOHIM. It reviews when use under licence is regarded as genuineuse, or valid for the purpose of establishing acquired distinctivenessor reputation. It also deals with OHIM decisions regarding licenseesfiling the licensors' trade marks in their own names. Practical significance: With respect to the standing of licensees as opponents or applicantsfor invalidity, this article explains the procedural requirements,mentioning also points to be considered when drafting trademark licences. The article also explains to what extent a licenceneed be proven where the opponent or cancellation applicanthas not used the earlier mark himself but wishes to rely onuse made by someone else. On the issue of a licensee filingthe licensed mark in his own name, the article gives an introductionto the criteria applied by OHIM and deals with his fiduciaryposition, resulting in a greater likelihood of his having actedin bad faith.  相似文献

This article analyses which of the major lessons learned from previous experiences in nation building have been applied or ignored in Iraq. It focuses on the first six months of the post‐combat period, a time frame generally recognised as being critical for laying the foundations for a stable and democratic future. A review of previous cases points to six lessons that, in fact, have been unlearned, and only two that have been realised in this initial phase in Iraq.  相似文献
