The radiological search for GSR is crucial in burnt material although it has been rarely tested. In this study, thirty‐one bovine ribs were shot at near‐contact range and burnt to calcination in an oven simulating a real combustion. Computed tomography (CT) and magnetic resonance (MR) were performed before and after carbonization and compared with former analyses with DR (digital radiography); thus comparing the assistance, the radiological methods can provide in the search for GSR in fresh and burnt bone. DR demonstrated the greatest ability in the detection of metallic residues, CT showed lower abilities, while MR showed a high sensitivity only in soft tissues. Thus, DR can be considered as the most sensitive method in the detection of GSR in charred bones, whereas CT and MR demonstrated much less reliability. Nonetheless, the MR ameliorates the analysis of gunshot wounds in other types of remains with large quantities of soft tissues. 相似文献

This paper will mainly focus on the EU approach to net neutrality, notably the adequacy of existing and future EU rules to tackle the issue and the ongoing policy debate. It will also consider whether the market has effectively worked around the regulatory lacunae by looking into the relationships between the telecoms industry, as a regulated sector, and the over-the-top (OTT) players. In this regard, it will explore to what extent there is a real battle between telcos and OTTs or if both parties are already finding their own ways to overcome their (apparent) disputes. 相似文献

Skull and Encephalic Injuries Caused by Beach Umbrellas: Case Reports and Review of Literature 下载免费PDF全文
Elvira Ventura Spagnolo M.D. Cristina Mondello M.D. Luigi Cardia M.D. Giuseppe Cannavò M.D. Giulio Cardia M.D. 《Journal of forensic sciences》2016,61(3):851-854
This study reports two unusual cases of skull‐encephalic injuries in bathers that were caused by violent impacts with beach umbrellas. The first case concerned a 36‐year‐old man who, while lying on a sun bed, was struck on his left temple by a beach umbrella, which had been blown away by a gust of wind. The second case concerned a six‐year‐old child who was struck on the right temporal region while he was playing on the sand. Both subjects died. A review of the literature was carried out. Various skull and brain injuries caused by several objects were found, but no injuries caused by beach umbrellas were detected. There were only cases of injuries caused by normal umbrellas. These cases showed that several objects can be responsible for traumas causing skull and brain injuries, therefore forensic investigation must be supplemented by circumstantial data. 相似文献

A nontargeted approach based on liquid chromatography equipped with a quadrupole time‐of‐flight mass detector (LC‐MS Q‐TOF) joined to nuclear magnetic resonance (NMR) analysis allowed rapid identification and quantification of the anti‐inflammatory drug aceclofenac in illegal Adderall tablets. The largest chromatographic peak had m/z = 354.030 and m/z = 376.012 matching, respectively, the ionic structures (M + H)+ and (M + Na)+ of a molecule M. The accurate mass data generated the molecular formula C16H13Cl2NO4. A screening of the pharmaceutical active substances having that molecular formula together with the MS/MS fragmentation pattern suggested aceclofenac. Aceclofenac structure was unambiguously confirmed by 1H and 13C NMR experiments. The aceclofenac content was 90 mg/tablet (RSD 2%) as detected by quantitative NMR. Information on the identity and content of illegal drugs is required for legal purposes; it supports in evaluating the effective impact on users safety, and it is useful for control laboratories using a targeted approach in their analytical activities. 相似文献

Determinants of the university technology transfer policy-mix: a cross-national analysis of gap-funding instruments 总被引:1,自引:0,他引:1
Federico Munari Einar Rasmussen Laura Toschi Elisa Villani 《The Journal of Technology Transfer》2016,41(6):1377-1405
University–industry technology transfer (TT) has become increasingly institutionalized and is supported by numerous reforms and initiatives at the national, regional and university levels. Most countries have implemented a policy mix involving a range of instruments to support the commercialization of research. Still, there is no systematic evidence indicating why the mix of policy instruments differs between countries. This study offers a novel cross-national investigation of the policy mix emphasizing the level of centralization and decentralization of policy instruments. We map and analyze two specific types of public instruments aimed at addressing the so-called funding gap in TT: proof of concept programs (POCs) and university-oriented seed funds (USFs). Based on a survey across 21 European countries, we find that such instruments are widely used but are organized differently depending on the level of implementation of TT practices in the country and the specific type of instrument considered. More precisely, we find a U-shaped relationship between the use of centralized gap-funding instruments and the country’s implementation of TT practices. Moreover, the type of gap-funding instrument (POC or USF) moderates this relationship. We discuss the implications of our findings and suggest that the policy mix of gap-funding instruments evolve with the maturity of the national TT infrastructure. 相似文献

The literature on Europeanisation in relation to Eastern Europe has posited the material incentives of EU membership as the main driver of domestic reforms aimed at adopting EU rules and norms (conditionality). But this fails to explain puzzling instances where no EU rule exists yet domestic change happens under European influence, or where the rule is a condition yet has little impact. As repositories of (dis)information, transnational networks can embolden a candidate country to breach the rules or influence it to comply with the ‘extra-conditionality’ the networks themselves create out of their own agendas. 相似文献

At Westminster, there are increasing pressures on select committees to publish in‐house legal advice. We suggest that examining the process of deciding to publish provides useful insights into the provision, reception, and use of legal advice, and the dynamics of select committees generally. We argue that the autonomy of select committees to decide what use they make of evidence and advice they receive is, in practice, constrained by the intra‐institutional dynamics and practices of select committees. Committee actors – parliamentarians, clerks, and parliamentary lawyers – each have overlapping, sometimes competing, roles. Most of the time, these roles and the responsibilities they encompass coincide, but the prospect of publication reveals clear tensions between the different actors. This is the politics of publication: the tactical approach of politicians is in tension with the stewardship of clerks and the professional norms of parliamentary lawyers. We suggest this tension will only increase in the near future. 相似文献

An Assessment of How Facial Mimicry Can Change Facial Morphology: Implications for Identification 下载免费PDF全文
Daniele Gibelli M.D. Ph.D. Danilo De Angelis D.D.S. Ph.D. Pasquale Poppa B.Sc. Ph.D. Chiarella Sforza M.D. Cristina Cattaneo M.D. B.Sc. Ph.D. M.A. 《Journal of forensic sciences》2017,62(2):405-410
The assessment of facial mimicry is important in forensic anthropology; in addition, the application of modern 3D image acquisition systems may help for the analysis of facial surfaces. This study aimed at exposing a novel method for comparing 3D profiles in different facial expressions. Ten male adults, aged between 30 and 40 years, underwent acquisitions by stereophotogrammetry (VECTRA‐3D ® ) with different expressions (neutral, happy, sad, angry, surprised). The acquisition of each individual was then superimposed on the neutral one according to nine landmarks, and the root mean square (RMS) value between the two expressions was calculated. The highest difference in comparison with the neutral standard was shown by the happy expression (RMS 4.11 mm), followed by the surprised (RMS 2.74 mm), sad (RMS 1.3 mm), and angry ones (RMS 1.21 mm). This pilot study shows that the 3D–3D superimposition may provide reliable results concerning facial alteration due to mimicry. 相似文献
