Development of a software package with GUI for the evaluation of monolithicity factors of RC jacketed columns
2023
The design of reinforced concrete (RC) jacketing for retrofitting substandard columns is a common practice when approaching the structural rehabilitation design of existing structures. In this framework, international technical codes suggest to assume the hypothesis of monolithic section and finally affecting the deduced performances by some empirical factors, known in the literature as monolithicity factors. The assessment of these coefficients is a difficult task, and only some rough assumptions can be found in the modern codes. This paper presents the development of a software package able to perform the static non-linear analysis of RC jacketed columns and evaluating the actual value of…
Obsidian from the Neolithic Layers of “Grotta di San Michele Arcangelo di Saracena” (Cosenza), Italy. A Preliminary Report
2021
Abstract The paper presents the results obtained by techno-typological analysis of a lithic assemblage from the Neolithic layers of Grotta San Michele Arcangelo di Saracena (Cosenza) together with the results of micro-wear analysis obtained from a preliminary selection of obsidian artifacts with different provenances distinguished by pXRF analysis. The site provides one of the best preserved Neolithic sequences in the area, from the earliest Impressed Wares (or Impresse Arcaiche) (early sixth millennium BC) to the Spatarella pottery style (end fifth – early fourth millennium BC). Along the Neolithic sequence, it is possible to observe some major changes within lithic resources management. I…
The beginning of the Neolithic in Southern Italy and Sicily
2018
Abstract The process of Neolithization of Southern Italy and Sicily covers about 500 years (6200–5700 cal BC) and involves two cultural horizons: Archaic Impressed Ware or “Impresse Arcaiche” and Advanced Impressed Ware or “Impresse Evolute”. In Southern Italy the Neolithic peopling from the East is characterized by a “package” of plenty domesticated plants and livestock; in Sicily the adoption of the new economical system is apparently more slow and with no evidences of ruptures between the Mesolithic groups and first farmers. In this paper we present the chronological and cultural framework of the sixth millennium BC within the area of investigation, with an up-to-date bibliography about …
Early pastoral communities in the mountains of Sicily. Prehistoric evidence from Vallone Inferno (Scillato) in the palaeoenvironmental framework of t…
2021
Abstract This paper discusses the Middle Neolithic and the Early Bronze Age phases of the occupation of a rock shelter at Vallone Inferno (Scillato, Palermo) in Sicily. Vallone Inferno is a key site for studying the early establishment and development of pastoralism in the prehistoric mountainous environments of Sicily. Seasonal use of the site as a shelter is documented for the earliest pastoral communities that exploited the Madonie mountain range. The results of the analysis of pottery and lithic assemblages contribute to the definition of two chronocultural frameworks that were linked by the same economic subsistence base. The special role of obsidian emerges, while the mobility pattern…
Petrographic characterization of quartzite tools from the Palaeolithic site of San Teodoro cave (Sicily): Study on the provenance of lithic raw mater…
2022
A petrographic characterization has been used here, for the first time, in the study of lithic raw materials exploited in prehistoric Sicily. Our research interests one of the oldest archaeological sites with evidence of the early human peopling of the island (∼15kyr ago): San Teodoro Cave, in northeastern Sicily. Two geological Formations, Numidian and Monte Soro Flysch gave origin to well-rounded pebbly quartzite elements scattered in the marine terraces surrounding the cave and likely exploited as one of the sources of the raw materials for the production of lithic tools by the Epigravettian communities having settled the place. The preference for one of the two qualities of quartzite is…
Experiments and results on obsidian tools: the case study of Le Rocche (Roccapalumba, Pa, Sicily) through microwear analysis.
2003
The results of the experimental activity related to the functional analysis of obsidian tools, coming from the Neolithic site of "Le Rocche" (Roccapalumba, Palermo), are discussed here.
New data on Sicilian prehistoric and historic evolution in a mountain context, Vallone Inferno (Scillato, Italy)
2013
Vallone Inferno rock-shelter is an archaeological site located in the Madonie mountain range in Sicily. Archaeological excavation and research have provided a long prehistoric and historic sequence from the Neolithic to the medieval period, this being the most complete work in this area at present. In this paper we present the preliminary data provided by a multidisciplinary study based on pottery, lithic, human, faunal and plant remains. Stratigraphic studies have identified four complexes, of which complex 3 has provided almost all the archaeological remains. 14C AMS dates, obtained from four samples, place the human activities between 2601 cal BC and 644 cal AD. These dates are coherent …
The small mammals (insectivores, bats and rodents) from the Holocene site of Vallone Inferno (Scillato, Sicily)
2013
The Vallone Inferno rock-shelter is an archeological site located at 770 m a.s.l. in the Madonie massif in Sicily. This massif is modeled into the Triassic and Oligocene sedimentary rocks of the Imerese Basin. Thearchaeological excavations conducted since 2008 have provided a long prehistoric and historic sequence from the Neolithic to the medieval period. From the four sedimentary complexes identified, only levels 3.4 to 3.1 from complex 3 and 4.2 from complex 4 have yielded small-mammal material. Level 4.2 is poor in remains and as yet without cultural ascription, though it has a radiocarbon age of 9450±50 years BP. Level 3.4 has yielded fragments of ceramic characteristic of the Middle N…
Al cuore del fantastico. Ibridi da pensare nel Paleolitico
2022
Our narrative abilities go back before Chauvet. Already the ivory figure of the so-called Hohlenstein-Stadel Lion-Man, dated to about 40,000 years ago, must be regarded as the most advanced product of a hundred if not a thousand years of figurative and narrative experimentation. In order to create this hybrid figure, as well the more or less theriomorphic figures which populate caves all over the world, the human mind must have possessed developed narrative skills. All the imaginary animals found in prehistoric art and all the teratologies found in caves, presuppose a narrative, more precisely the story of a metamorphosis. In this contribution I propose an interpretation that investigates t…
Recurrent Mesolithic–Neolithic occupation at Sise (western Latvia) and shoreline displacement in the Baltic Sea Basin
2016
A major assemblage of Mesolithic and Neolithic wooden artefacts has been recovered from the bed of the River Užava at Sise, in the coastal belt of western Latvia. New archaeological investigation has also produced wooden remains and other evidence of occupation on the riverbank. On the basis of multi-proxy environmental data and radiocarbon dating, this article offers a first attempt to place the human activity in a palaeolandscape context. The earliest evidence of human presence is provided by wooden artefacts dated to c. 10,500–9700 cal. BP, during the Ancylus Lake transgression. These remains are thought to reflect fishing activities in the shallows of the Ventspils Bay, which existed d…
