I materiali ceramici provenienti dal'US 5 del sito di Carzeranu (Settimo S. Pietro-Cagliari)
The paper concerns the pottery from US5 of the roman settlement of Carzeranu, Settimo San
Pietro (near Cagliari). The site are characterized by handcrafts and residential structures. The analysis of finds from US5 show the presence of coarse and fine wares from punic age to late antiquity (Terra Sigillata, African Red Slip, Black Glaze pottery, Thin-Walled pottery, amphorae and coarse wares)
Early metallurgy in Sardinia: characterizing the evidence from Su Coddu
This paper contextualizes analyses of a collection of metal artifacts and ostensible metallurgical slag from the prehistoric settlement of Su Coddu in south-central Sardinia (ca. 3400–2850 BCE). To characterize the types of metals and associated alloys utilized by the earliest residents of Su Coddu, two pins and an unshaped lump of unknown composition were analyzed using portable XRF spectrometry. In addition to metal artifacts, a large quantity of putative slag was discovered at the site that is consistently cited as the earliest evidence of in situ smelting in prehistoric Sardinia. To reconstruct firing temperatures and characterize mineral phases, four samples of the overfired material were selected for thin section petrography and powder XRD analysis. The results of this study indicate that the two pins were made of copper while the unshaped lump was composed of pure lead, making it the earliest lead-based artifact on Sardinia. XRD and petrographic analyses of the fired “slags” reveal that these samples are unrelated to metallurgical smelting and are likely burnt wall coatings whose mineralogical phases correspond with unfired plasters also recovered from the site. These results in combination contribute towards understanding early metallurgical practices in Sardinia and are relevant in reconstructing the events that have shaped the life history of Su Coddu
Sindrome PHACES possibile: emangioma toraco-brachiale associato a manifestazioni extracutanee = Possible PHACES syndrome: Segmental thoracobrachial hemangioma associated with extracutaneous manifestations
In PHACES syndrome a facial infantile hemangiomas (IH) is associated with extracutaneous manifestations involving the central nervous system, heart, blood vessels of head and neck, eye and sternum. Recently, an IH of the upper trunk was reported in association with extravcutaneous manifestations reminiscent of PHACES syndrome. Here we report a case of a 7-month-old girl with segmental hemangioma involving the upper trunk and limb. It was associated with structural anomalies similar to those reported in PHACES syndrome, including congenital heart disease, arterial abnormalities and a sternal defect; moreover there was a late-onset small hemangioma of the face
