Geophysics and cultural heritage. A living field of research for Italian geophysicists

2015

If one reads the World Heritage List 2002/2003, (http:// whc.unesco.org/archive/WHList02-ENG.pdf), a datum comes out with evidence: 12 countries have 253 World Heritage Sites (WHS) and all the 125 member countries have 586 WHS. Within these 12 countries Italy has 35 WHS corresponding to about 6% of the whole, followed by Spain, 5.8%, France, 4.6%, and the tenth has less than 2% of WHS. Cultural heritage is one of the greatest riches of Italy. Europe, with China, is the land which has the most stratified history in the world, and Italy is likely to still have undiscovered settlements dating from the prehistoric age to the 18th century. Some areas are totally unexplored, others have been only…

Tra mito e modello. Le cattedrali normanne nell'architettura religiosa del Cinquecento in Italia meridionale

2021

Talora ammantata da un alone mitico e sempre celebrata dalla storiografia di età moderna, la fondazione delle cattedrali al tempo della dominazione normanna costituisce per l’architettura religiosa in Sicilia un vero e proprio anno zero. Il primato nell’ambito della tipologia basilicale, per un verso, e il configurarsi come luoghi di attualità operativa, per altro verso, hanno fatto delle stesse i termini di riferimento privilegiati per l’architettura religiosa al principio dell’età moderna. Ciò si osserva, in particolare, in un’ampia e variegata casistica di chiese realizzate nel corso del XVI secolo, che ripropongono e reinterpretano temi compositivi e spaziali propri delle suddette catte…

The Role of Wastewater in Controlling Fluvial Erosion Processes on Clayey Bedrock

2023

In recent decades, fluvial erosion processes in highly anthropized areas are mainly associated with in-stream gravel mining activities or with the presence of artificial reservoirs which have increased the erosive capacity of the river as a consequence of the reduced sediment transport or the modification of the longitudinal profile of the channel. On the other hand, the role of pollutants in the degradation processes of soils with a predominantly clayey component is little known. The present study, through chemical analyses of water and mineralogical–geotechnical analyses of clayey soil samples taken along some river channels in central Italy in correspondence with water treatment pl…

L'abitare in pratica. Esperimenti nel post-sisma di Configno e Capricchia

2021

The seismic sequence that struck central Italy in 2016-2017 triggered intense de- and reterritorialization processes. This paper examines the cases of Capricchia and Configno (Amatrice, RI) where, with the active participation of non-residents owners of second homes, the communities have undergone autonomous processes in order to not abandon the place of residence while waiting for the institutional emergency solutions. Based on the perspective of social geography, this paper intends to analyze the bottom-up reterritorialization processes and open the discussion on the value and legitimacy of intervention of non-resident subjects.

Polychlorinated Biphenyls in Sediments from Sicilian Coastal Area (Scoglitti) using Automated Soxhlet, GC-MS, and Principal Component Analysis

2014

A methodology for the PAHs and PCBs congener determination in sediment samples has been revised. We determined the distributions of PAHs and PCBs in the superficial sediments of the Scoglitti (Italy) coastal area to provide data for comparison with other marine systems and to hypothesize the sources. Extraction yield, for PCB, was never less than 60% in most cases, while for PAHs, utilizing perdeuterated surrogate standard (benz[a]anthracene-d12 and anthracene-d10) was never less than 72%. The total concentration of the 16 PAHs investigated, expressed as the sum of concentrations, PAHs, varied from 1–5087 μg/kg of dry matrix, while the PCBs ranged from detection limit to 36 μg/kg of dry mat…

Contamination from polycyclic aromatic hydrocarbons (PAHs) in the soil of a botanic garden localized next to a former manufacturing gas plant in Pale…

2010

The Botanical Garden lies within the city of Palermo, a few meters away from one of the largest unused Manufacturing Gas Plant in Sicily. The total concentrations of PAHs (23 compounds) in the soil of Botanical Garden ranged from 947 to 18,072 microg/kg. The wide range of PAH concentrations (RSD=84%) found in the soil samples indicates heterogeneous levels of contamination in the area and this can be explained by considering the different tree distributions which prevents the homogeneous deposition of pollutants on the soil. Soils collected in the Botanical Garden generally showed the highest PAH concentrations, being almost 2-3 times higher than the concentration samples obtained in the ur…

The Impact on Healthcare Workers of Italian Law n. 24/2017 “Gelli–Bianco” on Patient Safety and Medical Liability: A National Survey

2022

Italian “Gelli–Bianco” law (law n. 24 enacted by the Italian Government on 8 March 2017) introduced innovative changes and regulations regarding patient safety and healthcare workers’ (HCWs) liability. We promoted a national survey to evaluate the effect of the law on HCWs. The questionnaire was edited and distributed using the free online tool “Google Forms” (Google LLC). The mode of administration chosen for the questionnaire was telematic self-completion. In particular, the questionnaire was sent to several portals of information, websites, in the scientific and medical sectors. Four hundred forty-five subjects participated in the survey. The differenc…

MRSA ST22-IVa (EMRSA-15 clone) in Palermo, Italy

2010

Summary: Epidemic spread of methicillin-resistant Staphylococcus aureus (MRSA) strains carrying the Staphylococcal Chromosomal Cassettes (SCC) mec type IV is being increasingly reported in many geographical areas. A survey to determine the prevalence and characteristics of MRSA SCCmec IV isolates identified in four general hospitals in Palermo, Italy, was carried out. During the period February–June 2009, SCCmec type IVa has been found in 12 out of 94 isolates. Nine isolates from all hospitals and all strains from a NICU outbreak occurring in the same period were attributed with the ST22-IVa (EMRSA-15) clone. In our setting, due to the changing MRSA epidemiology, detection of SCCmec IV coul…

Epidemic dissemination of Salmonella enterica spp. enterica serovar Bovismorbificans in southern Italy in the years 1989-1991.

1994

Epidemic strains of Salmonella enterica subsp. enterica serovar Bovismorbificans isolated in southern Italy during the years 1989-1991 were submitted to a molecular epidemiological study in comparison with isolates identified in the years 1980-1988 in the same geographic area. Genomic DNA fragments obtained by digestion with BglI or Eco RI hybridized with Escherichia coli rRNA to produce three distinct, but highly related patterns. Ribotype 1, which had never been identified before 1989, was found to characterize most of the strains identified between 1989 and 1991. Such a finding supports the hypothesis of emergence and spread of a new bacterial clone associated with the increased number o…
