The majority of the artifacts are made in quartz varieties (with minor occurrences of flint). Milky quartz is dominant, being similar to diverse occurrences of quartz veins in the immediate neighborhood. There are diverse other quartz varieties, indicating the possibility of locations farther away from the shelter. The study of geological raw materials can be seen as an important source of archaeological information, illustrating the evolution of past relationships between humans and geological resources, and also providing relevant information for the present and future, considering namely the extremely low environmental impact of the processing of raw materials.

The remanence of the murals is shown, using X-ray analyses, to be carried by haematite. Murals in Thermae Stabianae, known to have been painted a few years before Ž .

To gain more insight in the relevance of Ser129-p and CTT aSyn under physiological and pathological conditions, we investigated their subcellular distribution patterns in normal aged and PD brains using highly-selective antibodies in combination with 3D multicolor STED microscopy. We show that CTT aSyn localizes in mitochondria in PD patients and controls, whereas the organization of Ser129-p in a cytoplasmic network is strongly associated with pathology. Nigral Lewy bodies show an onion skin-like architecture, with a structured framework of Ser129-p aSyn and neurofilaments encapsulating CTT aSyn in their core, which displayed high content of proteins and lipids by label-free CARS microscopy. The subcellular phenotypes of antibody-labeled pathology identified in this study provide evidence for a crucial role of Ser129-p aSyn in Lewy body formation. .

Its bluish grey appearance is due to Rayleigh scattering by sub-microscopic inclusions and is not related to an intervalence charge transfer process. In light of historically documented extensive trade relations between ancient Rome and Ethiopia (the kingdom of Aksum), we hypothesise that the recently documented basalt-related sapphire deposits in northern Ethiopia are a possible source of raw material for this Roman intaglio (as well as other basaltic sapphires used in Roman times), in addition to previously held views that ancient sapphires originate from deposits in Sri Lanka, France and perhaps South East Asia. This rare opportunity to characterise in detail one of the very few engraved sapphires from the Roman period permits a better understanding of gem materials used in classical antiquity

Apart from disease and starvation, the largest number of human deaths caused by explosive eruptions in the twentieth century are due to pyroclastic flows. The relationship between the number of victims related to a specific hazard and the presence of urban settlements in the area covered by the eruption has been shown. However, pyroclastic falls are also extremely dangerous under certain conditions. These conclusions are based on archaeological and volcanological studies carried out on the victims of the well-known AD 79 eruption of Vesuvius that destroyed and buried the Roman city of Pompeii. The stratigraphic level in the pyroclastic deposit and the location of all the casualties found are described and discussed. The total number of victims recovered during the archaeological excavations amounts to 1150. Of these, 1044 well recognisable bodies plus an additional group of 100 individuals were identified based on the analysis of several groups of scattered bones. Of the former, 394 were found in the lower pumice lapilli fall deposit and 650 in the upper stratified ash and pumice lapilli pyroclastic density currents (PDCs) deposits. In addition, a tentative evaluation suggests that 464 corpses may still be buried in the unexcavated part of the city. According to the reconstruction presented in this paper, during the first phase of the eruption (August 24, AD 79) a huge quantity of pumice lapilli fell on Pompeii burying the city under 3 m of pyroclastic material. During this eruptive phase, most of the inhabitants managed to leave the city. However, 38% of the known victims were killed during this phase mainly as a consequence of roofs and walls collapsing under the increasing weight of the pumice lapilli deposit. During the second phase of the eruption (August 25, AD 79) 49% of the total victims were on the roadways and 51% inside buildings. All of these inhabitants, regardless of their location, were killed by the unanticipated PDCs overrunning the city. New data concerning the stratigraphic level of the victims in the pyroclastic succession allow us to discriminate between the sequential events responsible for their deaths. In fact, casts of some recently excavated corpses lay well above the lower PDCs deposit, testifying that some of the inhabitants survived the first pyroclastic current. Finally, during the PDCs phase the victims died quite rapidly by ash asphyxiation. From the attitude of some casts, it seems that some people survived the initial impact of the second pyroclastic current and tried to support head and bust during the progressive aggradation of the deposit at the base of the current.

Si tratta di un’area collinare, solcata da profondi canaloni, che è stata completamente alterata nei primi anni Ottanta, quando si è iniziata la costruzione di un parco pubblico urbano: la realizzazione di strade interne, con il conseguente sviluppo edilizio abusivo, nonché la costruzione di vialetti e di altre infrastrutture, senza tener conto della rete di sentieri preesistenti, ha profondamente compromesso il paesaggio, rendendo problematico qualunque tentativo di identificazione della conformazione del territorio nell’antichità. L’attività di ricognizione, ove possibile, è stata perciò effettuata «a tappeto» utilizzando carte in scala 1:4000. Per un inquadramento storico dell’area, ancora attribuibile nei Campi Flegrei, si vedano Amalfitano et al. (1990). Inoltre si rimanda agli articoli riguardanti i rin...
