Ricerche di Archeologia cristiana e bizantina nella Sicilia occidentale
2017
The seventh Quaderno Digitale di Archeologia Postclassica contains the results of the researches conducted by the Department of Cultural Heritage of the University of Palermo and by the Pontificia Commissione di Archeologia Sacra in the Early Christian catacomb of Villagrazia di Carini during the years 2013-2014. Emma Vitale and Fortunatina Vaccaro present the stratigraphic excavation carried out in the south-eastern district of the cemetery, while, in the third study of the book, Giuseppe Falzone analyzes two painted funerary inscriptions on the interior walls of Byzantine burials brought to light, in recent years, along the Decumanus Maximus of Lilybaeum.
Sulfur isotope's signal of nanopyrites enclosed in 2.7 Ga stromatolitic organic remains reveal microbial sulfate reduction.
2018
18 pages; International audience; Microbial sulfate reduction (MSR) is thought to have operated very early on Earth and is often invoked to explain the occurrence of sedimentary sulfides in the rock record. Sedimentary sulfides can also form from sulfides produced abiotically during late diagenesis or metamorphism. As both biotic and abiotic processes contribute to the bulk of sedimentary sulfides, tracing back the original microbial signature from the earliest Earth record is challenging. We present in situ sulfur isotope data from nanopyrites occurring in carbonaceous remains lining the domical shape of stromatolite knobs of the 2.7-Gyr-old Tumbiana Formation (Western Australia). The anal…
Planning Punic cities: Geophysical prospection and the built environment at Motya, Sicily
2020
The urban plan of ancient Motya on the Isola di San Pantaleo on the west coast of Sicily and its relationship to developments in Phoenician and Punic societies have been investigated since the early 1960s. Data from geophysical surveys in the north-eastern quadrant of Motya show the regular organisation of urban insulae framed by two broad roads. These results, combined with data from previous nearby excavations, improve the modelling of Motya's layout, and contribute to the wider discussion of Phoenician/Punic and broader Mediterranean urban traditions between the sixth and fourth centuries BC.
The production of western Greek amphorae in Agrigento (Southern Sicily): An archaeometric and archaeological characterisation of the late 6th-4th cen…
2022
This paper aims at an interdisciplinary, archaeological and archaeometric characterisation of the western Greek amphorae series produced in late Archaic and Classical-period Agrigento (southern Sicily). The research is based on a macroscopic examination, according to the standardised methods of Fabrics of the Central Mediterranean (FACEM), combined with petrographic analyses of 21 amphorae samples of presumed local fabric found in Agrigento itself. These were found in the artisanal area outside Porta V, in the excavations South of the temple of Zeus, and in several Sicilian consumption sites. Furthermore, a selection of 12 coarse ware samples and three tiles, all of supposed local manufactu…

A presença fenícia em Lisboa: novos vestígios descobertos no alto da colina do Castelo de São Jorge
2018
Neste trabalho apresentam-se os primeiros contextos bem caracterizados da fase inicial da ocupação da Idade do Ferro na Colina do Castelo de São Jorge, em Lisboa (Portugal). Escavações arqueológicas realizadas nesta área urbana permitiram, pela primeira vez, detectar uma sequência clara da ocupação da fase Orientalizante da cidade, que se inicia durante o século VII e se prolonga até ao século V a.C. Os vestígios estratigráficos, arquitectónicos e o espólio recolhido, que integra sobretudo ânforas, produções cinzentas, de engobe vermelho, vasos de fabrico manual e cerâmica comum e pintada, são analisados com detalhe, revelando o profundo carácter orientalizante das populações que se instala…
XRF and LA-ICP-MS studies of gold and silver artefacts from a 12–13th century CE tumulus in Senegal: Implications for the medieval African gold trade
2019
Abstract Silver and gold artefacts from a 12–13th c. CE tumulus in Senegal were recently analysed by means of XRF and LA-ICP-MS. The identification of major, minor and trace elements allowed gaining a rare insight into the composition of precious metals circulating in that part of Africa in medieval times. The results show that all objects were made of polymetallic alloys. Comparisons with analyses from other West African as well as North African and European silver and gold artefacts suggest that the metal from the studied objects most probably originate from outside West Africa. At least in the case of the gold artefacts, this is quite surprising, as we expected to come across pure West A…

Chemical and Microbiological Characterization for PDO Labelling of Typical East Piedmont (Italy) Salami
2015
This study is focused on the characterisation of typical salami produced in Alessandria province (North West of Italy). Seventeen small or medium salami producers from this area were involved in the study and provided the samples investigated. The aim is double and consists in obtaining a screening of the characteristics of different products and following their evolution along ripening. The study involved five types of typical salami that were characterised for aroma components and nutritional features. This approach could provide a basis for a possible PDO or PGI label request. Principal Component Analysis and cluster analysis were used as multivariate statistical tools for data treatment…
Daily Peak Temperature Forecasting with Elman Neural Networks
2005
This work presents a forecaster based on an Elman artificial neural network trained with resilient backpropagation algorithm for predicting the daily peak temperatures one day ahead. The available time series was recorded at Petrosino (TP), in the west coast of Sicily, Italy and it is composed by temperature (min and max values), the humidity (min and max values) and the rainfall value between January 1st, 1995 and May 14th, 2003. Performances and reliabilities of the proposed model were evaluated by a number of measures, comparing different neural models. Experimental results show very good prediction performances.
