The first casts of the forms of Pompeian victims of the AD 79 eruption of Mt Vesuvius were successfully achieved under the directorship of Giuseppe Fiorelli in 1863. To date, 104 individuals have been cast by restorers and archaeologists during the course of excavation. The methods used to obtain these casts were not well documented. It was always assumed that plaster or lime cement was merely poured into voids which preserved the impression of organic remains buried in the ash that covered the site during the catastrophe. It was also assumed that the undisturbed skeletal remains of victims were encased within the casts. The initial aim of the Pompeii Cast Project was to study these bones to build on and test the results of an earlier study of the large sample of Pompeian human remains that were disarticulated by post-excavation activities. Apart from providing information about the people who did not manage to escape the eruption, the project aimed to challenge previous interpretations of the lives and activities of these victims that were solely based on superficial inspection and circumstantial evidence. Twenty-six casts were subjected to CT scanning or X-ray analysis in 2015. The results were unexpected. It was clear that the casts had been considerably manipulated. Bones were often removed prior to casting, and other elements had been introduced. This ongoing project has now been expanded to establish how these casts were achieved, to better understand nineteenth- and twentieth-century archaeological and restoration practice.

Abstract—The type material on which the fossil genus name Ampelocissites was established in 1929 has been reexamined with the aid of X-ray micro-computed tomography (μ-CT) scanning and compared with seeds of extant taxa to assess the relationships of these fossils within the grape family, Vitaceae. The specimens were collected from a sandstone of late Paleocene or early Eocene age. Although originally inferred by Berry to be intermediate in morphology between Ampelocissus and Vitis, the newly revealed details of seed morphology indicate that these seeds represent instead the Ampelopsis clade. Digital cross sections show that the seed coat maintains its thickness over the external surfaces, but diminishes quickly in the ventral infolds. This feature, along with the elliptical chalaza and lack of an apical groove, indicate that Ampelocissites lytlensis Berry probably represents Ampelopsis or Nekemias (rather than Ampelocissus or Vitis) and that the generic name Ampelocissites may be useful for fossil seeds with morphology consistent with the Ampelopsis clade that lack sufficient characters to specify placement within one of these extant genera.

AbstractAlthough malaria is one of the oldest and most widely distributed diseases affecting humans, identifying and characterizing its presence in ancient human remains continue to challenge researchers. We attempted to establish a reliable approach to detecting malaria in human skeletons using multiple avenues of analysis: macroscopic observations, rapid diagnostic tests, and shotgun-capture sequencing techniques, to identify pathological changes, Plasmodium antigens, and Plasmodium DNA, respectively. Bone and tooth samples from ten individuals who displayed skeletal lesions associated with anaemia, from a site in southern Egypt (third to sixth centuries AD), were selected. Plasmodium antigens were detected in five of the ten bone samples, and traces of Plasmodium aDNA were detected in six of the twenty bone and tooth samples. There was relatively good synchronicity between the biomolecular findings, despite not being able to authenticate the results. This study highlights the complexity and limitations in the conclusive identification of the Plasmodium parasite in ancient human skeletons. Limitations regarding antigen and aDNA preservation and the importance of sample selection are at the forefront of the search for malaria in the past. We confirm that, currently, palaeopathological changes such as cribra orbitalia are not enough to be certain of the presence of malaria. While biomolecular methods are likely the best chance for conclusive identification, we were unable to obtain results which correspond to the current authentication criteria of biomolecules. This study represents an important contribution in the refinement of biomolecular techniques used; also, it raises new insight regarding the consistency of combining several approaches in the identification of malaria in past populations.

Abstract Since the publication of the “restitution report” by Felwine Sarr and Bénédicte Savoy in November 2018, the debate around the restitution of African artifacts inherited from German colonialism in German museums has become increasingly intense. While the restitution debate in Germany is generally focused on “material cultural heritage” and human remains, this reflection attempts to contextualize the “immaterial heritage” (museum collections inventory data, photographs, movies, sound recordings, and digital archive documents) from German colonialism and plead for its consideration in this debate. It claims that the first step of restitution consists of German ethnological museums being transparent about their possessions of artifacts from colonial contexts, which means providing all available information about museum collections from colonial contexts and making them easily accessible to the people from the former German colonies.

To the dismay of today's social progressives, the Argentine Catholic church addresses the moral situation of its people but also shies away from specific political positions or other hint of secular involvement. At the beginning of the twentieth century, the church set out to secure its place in national leadership by strengthening religious institutions and withdrawing clergy from politics. The church struggled to overcome a heritage of organizational weakness in order to promote evangelization, that is, to extend its spiritual influence within Argentina. The bishop of the central city of Córdoba, Franciscan Friar Zenón Bustos y Ferreyra (1905-1925), reinforced pastoral care, catechesis, and education. After 1912, as politics became more heated, Bustos insisted that priests abstain from partisan activities and dedicate themselves to ministry. The church casts itself in the role of national guardian, not of the government, but of the faith and morals of the people.

Abstract Friction stir welding (FSW) is a novel welding method that is garnering attention, in part, due to its ability to join dissimilar materials. One of the challenges in producing dissimilar friction welded joints is ensuring the welds are defect-free. Nondestructive testing (NDT) methods such as ultrasonic waves, gamma rays, X-rays, and X-ray CT, are gaining popularity as a method to detect internal defects in FSW joints. In this study, dissimilar AA1050-AA6061-T6 FSW lap welds are Manufactured and then examined using an NDT X-ray CT technique. The effects of two critical X-ray CT scanning parameters (voxel size and Hounsfield unit (HU)) on the detection of internal defects are investigated. The samples are scanned via X-ray CT at two different voxel sizes (2.457 E−02 and 1.420 E−03 mm3) and two HU ranges (12-bit and 16-bit depth). The generated Digital Imaging and Communications in Medicine (DICOM) images are segmented based on a proper HU threshold found via the Otsu thresholding method. The findings show that Small voxel size (higher resolution) improves the ability of detecting internal defects and improves the effectiveness of the thresholding process. Higher HU range results in a wider separation between detected material peaks, thus enhancing the effectiveness of the thresholding process as well.
