Secondary Minerals From Italian Sulfuric Acid Caves
2017
Italy is a country hosting a large number of hypogenic sulfuric acid (SAS) speleogenesis caves, mostly located along the Apennine chain, but also in Campania (along the coastline of Capo Palinuro), Apulia (along the coastline of Santa Cesarea Terme) and Sicily. Besides the typical morphologies related to their special geochemical origin (cupolas, replacement pockets, bubble trails, etc), these caves often host abundant secondary mineral deposits, mainly gypsum, being the result of the interaction between the sulfuric acid and the carbonate host rock. Native sulfur deposits are also well visible on the ceiling and roof, and peculiar sulfuric acid minerals such as jarosite, alunite, and other…
Architetture artificiali “per via di levare”. Una cava di calcarenite.
2020
Nel 1756, Pietro Bellaroto acquistò una chiusa di "terre scapole" nella Fossa della Garofala; questa gli fu poi alienata nel 1759 a favore di Giovanni Gerardi. Per tutto il XVII secolo il Bellaroto aveva iniziato a coltivare una cava di pietra (pirrera, dal termine spagnolo pedrera), la cui produzione lapidea venne utilizzata per la costruzione di molti edifici palermitani, intra ed extra moenia; la cava veniva chiamata pirrera di Bellaroto e la pietra prodotta era definita "forte", di buona qualità.

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…
Immaginazione
2022
The most recent discoveries deriving from the exchanges between aesthetics and neuroscience – especially those stressing the importance of the sensory-motor system in both scientific and aesthetic experience – have raised a particular attention on the subjectivity of mental processes, especially those related to the knowledge processes, and on the role of imagination. These results have, still nowadays, influence and confirmation in literature, which many scholars interested in a cognitivistic approach consider as related, if not just the same, to the ability of mankind to make tools and, thus, to make sense. An example of this reciprocal influence of neuroscience and literature is without …

Adrenal cavernous hemangioma: which correct decision making process?
2016
Introduction: Cavernous hemangioma of the adrenal gland is a rare benign tumor characterized by the presence of blood-fil- led, dilated vascular spaces. These adrenal masses are usually non-functioning and the patients have no symptoms so the diagnosis is incidental. Methods: We performed a systematic literature review for all articles published until April 2015. The initial search identified 98 publications. We considered some characteristics: the mean age of the patients at diagnosis was 59 years (range 19 - 84); there were approximately 1.7 times more female patients than male patients; mean diameter of the lesions was 10.3 cm (range 2 - 25). Surgical treatment was more often open with m…
Cavernous haemangioma of the external auditory canal: clinical case and review of the literature
2012
Although benign vascular lesions are frequent in the head and the neck region, clinical evidence of cavernous haemangioma of the external auditory canal is extremely rare; when present, the lesion invades the middle ear space. Herein, a rare case of a soft mass filling the external auditory canal, not involving the tympanic membrane, in a symptomatic 59-year-old male is described. Clinical and audiological characteristics, imaging studies and surgical treatment with histological evaluation are reported, which led to a diagnosis of a cavernous haemangioma. This is only the seventh case described in the literature, to date, not involving the tympanic membrane and the middle ear space. In addi…
