Human primary teeth start to form between the sixth and eighth week of prenatal development. An accentuated marking line, the neonatal line (NNL), forms at birth caused by the physiological changes. The NNL identification is the only method in paleoanthropological studies that allows us to distinguish if a child died before or after birth and to calculate an infant's exact period of survival, but it is difficult to determine. Dean et al (2019) recently discover thet NNL coud be detected by SRXRF, by the increment of Zn (20-100 ppm). We want to determine the chronological age of perinatal skeletal remains and establish mortality patterns in 22 individuals of Iberian archaeological site of Olerdola (Spain) and analyze them using SRXRF. This study will help provide insights into the practices of infanticide in Iberian culture and contribute to the field of physical and forensic anthropology.

This proposal is a continuation of the HG-172 BAG experiment, a new access route to the ESRF structural analysis capacities for the Heritage Science community. The upgrade to the ESRF-EBS was the triggering element to propose a single block allocation group (BAG). Two complementary analytical configurations are used in the BAG: High angular resolution XRD (ID22) and High lateral resolution XRD (ID13). The combination of these two beamlines generates precious clues on the origin, processing and degradation of historical materials. By relying on the new analytical capacities of the EBS combined with optimized access route, sample preparation procedures and processing pipelines, the Heritage BAG has proven to be a very efficient way to increase the output of the Cultural Heritage community, to reinforce a scientific network of expert users structured around the ESRF, and to initiate new European collaborations in Heritage Science.

The ESRF has been asked to help for the preparation of the restoration of the old violin called the "Cannone" that was played by Paganini in the late 18th century. This invaluable violin needs to be repaired, but due to the extent of degradations, and considering that it is still played regularly, a very detailed assessment of its present state is required. BM18 with its hierarchical propagation phase contrast microtomography capabilities with low dose setup is currently the best location in the world to conduct this study. Nevertheless, considering the importance of this violin, a dry run with another less valuable violin, as well as a modern copy of the Cannone is required to test all the protocols, including the control of the humidity and dosimetry. This proposal hence covers both the dry run on the two test violins and the real experiment. It is performed on directors contingency beamtime.
