A Comparison Between Digital Radiography,Computed Tomography,and Magnetic Resonance in the Detection of Gunshot Residues in Burnt Tissues and Bone

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.     

The EU approach to net neutrality: Network operators and over-the-top players,friends or foes?

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.     

Skull and Encephalic Injuries Caused by Beach Umbrellas: Case Reports and Review of Literature

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.     

Counterfeit Adderall Containing Aceclofenac from Internet Pharmacies

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.     

East Side Story: How Transnational Coalitions Contested EU Conditionality

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.     

The Application of Flow Cytometry as a Rapid and Sensitive Screening Method to Detect Contamination of Vitreous Humor Samples and Avoid Miscalculation of the Postmortem Interval

Research into maximizing the speed, precision, and reliability of estimating the postmortem interval (PMI) has been a recurring object of investigation and methodologies based on the vitreous humor (VH) have provided good results. However, contamination from causes not readily apparent, such as blood, can occur, and thus lead not only to an erroneous estimation of PMI, but also interfere with the correct identification of other substances in the VH. We have developed a flow cytometry method which quantifies blood contamination and is able to detect erythrocytes in 1:750,000 dilution of contaminated VH which affects the results of hypoxanthine. It is an improvement on the previous more complex mass spectrometry method, being faster, more sensitive, and readily available. As such, it could be proposed for the rapid screening of appropriate samples by detecting and eliminating blood contaminated samples from PMI estimation.     

An Assessment of How Facial Mimicry Can Change Facial Morphology: Implications for Identification

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.     

The Reliability of Facial Recognition of Deceased Persons on Photographs

In humanitarian emergencies, such as the current deceased migrants in the Mediterranean, antemortem documentation needed for identification may be limited. The use of visual identification has been previously reported in cases of mass disasters such as Thai tsunami. This pilot study explores the ability of observers to match unfamiliar faces of living and dead persons and whether facial morphology can be used for identification. A questionnaire was given to 41 students and five professionals in the field of forensic identification with the task to choose whether a facial photograph corresponds to one of the five photographs in a lineup and to identify the most useful features used for recognition. Although the overall recognition score did not significantly differ between professionals and students, the median scores of 78.1% and 80.0%, respectively, were too low to consider this method as a reliable identification method and thus needs to be supported by other means.     

Effects of Cremation on Fetal Bones

The charring process is a weak point of anthropological analysis as it changes bone morphology and reduces information obtainable, specially in fetuses. This experiment aims at verifying the conservation of fetal bones after cremation. A total of 3138 fetuses of unknown sex and age were used, deriving from legal and therapeutic abortions from different hospitals of Milan. Cremations took place in modern crematoria. Nine cremation events were analyzed, each ranging from 57 to 915 simultaneously cremated fetuses. During the cremations, 4356 skeletal remains were recovered, 3756 of which (86.2%) were morphologically distinguishable. All types of fetal skeletal elements were found, with the exception of some cranial bones. Only 3.4% of individuals could be detected after the cremation process, because of the prevalence of abortions under 12 lunar weeks. All fire alterations were observed and the results were statistically analyzed. This pilot study confirmed the possibility of preservation of fetal skeletal elements after cremation.
