Survey and inventory of artificial cavities in the historical centre of Genoa (Italy): a contribution to the development of an experimental Underground Master Plan
No full textMediterranean cities record the multi-layered nature of phases of urban expansion: historical centres, generally settled in ancient times, underwent significant expansion from the Middle Ages and progressively
grew over time (Faccini et al., 2020). Since the second half of the 19th century, and later after the Second World
War, cities have undergone uncontrolled development and sometimes irrational urban sprawl.
The morphological modifications of the natural topography have taken place over time, not only in terms
of land surface (excavations, filling, sea embankments, hydrographic network modifications), but also with
underground works (urban hypogea of a hydraulic, civil, religious, war, mining and transport nature).
The city of Genoa, and in particular its historical centre, shows both significant morphological changes of
the original morphology, and on a dense network of underground environments occupying several hectares of
subsoil (Bixio et al., 2017, 2019).
These artificial cavities can be analysed either in terms of the potential impact of urban development at
land surface on underground spaces, and in terms of geomorphological risk associated with the instability of
artificial cavities and consequent propagation of deformations at ground level. In addition, climate change is
leading to an intensification of meteo-hydrological phenomena whose ground effects may trigger sink-hole
phenomena.
This study presents, on the basis of archive research and original underground surveys, the results of the
artificial cavities inventory in the historic centre of Genoa, characterised by great hydro-geomorphological and
urban complexity.
The database developed will provide insight into specific urban planning interventions aimed at the
conservation and management of Genoa’s artificial cavities, which represent a unique cultural heritage and a
resource for their historical and socio-economic importance.
The results can represent the starting point of a specific urban planning tool: an underground master plan, as
already developed by other European cities, which is fundamental for sustainable and resilient urban planning

Lormetazepam addiction: data analysis from an Italian medical unit for addiction
No full textMarco Faccini,1 Roberto Leone,2 Benedetta Pajusco,1 Gianluca Quaglio,1 Rebecca Casari,1 Anna Albiero,1 Monia Donati,2 Fabio Lugoboni11Department of Internal Medicine, Addiction Unit, 2Pharmacology Unit, Reference Center for Education and Communication within the World Health Organization Program for International Drug Monitoring, University Hospital of Verona, Verona, ItalyBackground: The purpose of this study was to determine, in the context of a hospital addiction unit, which benzodiazepines were abused and to look for correlations with the characteristics of detoxified patients.Methods: A retrospective study was carried out using the database of hospital admissions to the addiction unit for detoxification from 2003 to 2010.Results: Of 879 admissions to the addiction unit during the seven-year period, 281 were for benzodiazepines. The percentage of patients addicted only to benzodiazepines was higher among females than males. Benzodiazepine consumption had started as a drug addiction behavior in only 10% of cases. The main sources of prescription identified were general practitioners (52% of cases) or compliant pharmacists (25%). Overall, 15 different benzodiazepines were abused, with lormetazepam being the most commonly used (by 123 patients, 43.8% of the total).Conclusion: Our data show that, outside the population of multidrug addicts, there is an underestimated group of chronic benzodiazepine consumers who are often not referred to medical institutions for treatment. Even in the group of patients addicted to one substance only, we observed an abnormal number of requests for detoxification from lormetazepam, which appears to be more "popular" than other benzodiazepines. This drug should be prescribed according to stricter criteria and submitted to closer control.Keywords: lormetazepam, benzodiazepines, addiction, inpatient detoxificatio
Intrinsic environmental vulnerability as shallow landslide susceptibility in environmental impact assessment
No full textThis work investigated the susceptibility factors that trigger shallow landslides. In particular, the objective of the research was the implementation of a method to determine the relevant factors that can trigger shallow landslide events. However, with respect to the existing methods, the integration with historical datasets and the inclusion of spatial factors displaying dynamics in the same characteristic timescales were specific features of the developed tool. The study area included the watersheds of the Sessera and Strona rivers in the alpine area of the Province of Biella (Piedmont, NW Italy). The method was developed and tested from two sub-datasets derived from an integrated dataset that referred to an intense event, involving the same area, that occurred in 1968 (2-3 November). This allowed the implementation of an integrated representation of landslides' predisposing factors and the identification and classification in different groups of the areas susceptible to geo-hydrological instability processes. The previously existing databases were verified and integrated into a geographic information system (GIS) environment, giving a potentially sharable source of information for planning purposes. The obtained maps represent a metric of one of the possible intrinsic environmental vulnerability factors for the area under study. Consequently, this method can represent a future instrument for determining the intrinsic environmental vulnerability dependent on landslides within an environmental impact assessment (EIA), as required by the most recent European regulation on EIA. Moreover, the shared information can be used to implement informed policy and planning processes, based on a bottom-up approach. In particular, the availability online of landslide susceptibility maps could support the generation of augmented information-useful for both local administrators and planners as well as for stakeholders willing to implement specific projects or infrastructure in vulnerable areas, such as mountains

Metasomatism induced by alkaline magma in the upper mantle of northern Victoria Land (Antarctica): An experimental approach
No full textMagma generation in the Ross Sea system is related to partial melting of strongly
metasomatised mantle sources where amphibole most probably plays a crucial role. In this
context, metasomatism induced by a mela-nephelinite melt in lithospheric mantle of the Mt.
Melbourne Volcanic Province (northern Victoria Land – NVL, Antarctica) was investigated
experimentally studying the effects of melt interaction with lherzolite at 1.5-2.0 GPa and
T=975-1300°C, and wehrlite at 1.0 GPa and T=1050-1250°C. The experiments were
designed to induce melt infiltration into the ultramafic rocks. The observed modifications in
minerals are compared with those found in mantle xenoliths from NVL. The effects of
metasomatic modifications are evaluated on the basis of run temperature, distance from the
infiltrating melt and on the diffusion rates of chemical components. Both in lherzolite and
wehrlite, clinopyroxene exhibits large compositional variations ranging from primary
diopside to high Mg-Cr-(Na) augitic and omphacitic clinopyroxenes in lherzolite, and to
low Mg and high Ti-Al-Fe-Na augites in wehrlite. Olivine (in wehrlite) and spinel (in
lherzolite) also result compositionally modified, the former shows enrichments in Fe, the
latter displays a higher Cr/(Cr+Al) ratio. The systematic variations in mineral compositions
imply modifications of the chemistry of the infiltrating melt as recorded by the glass
veinlets and patches observed in some charges. In experiments involving wehrlite
paragenesis, the glass composition approaches that of melt patches associated to both
amphibole-free and amphibole-bearing natural samples, and is related to
olivine+clinopyroxene crystallisation coupled with primary clinopyroxene dissolution at the
contact between the metasomatising melt and the solid matrix. Even if amphibole
crystallisation was not attained in the experiments, we were able to explain the occurrence
of amphibole in the natural system considering that in this case a hot metasomatising melt
infiltrates a cooler matrix.Published279-3022.3. TTC - Laboratori di chimica e fisica delle rocceN/A or not JCRope
