Hundreds of landslides were triggered by the mainshocks (up to Mw 6.5) that occurred in 2016 in Central Italy during the seismic sequence that originated in the Apennine and ended in January 2017. These landslides were studied via field-based investigation and remote sensing techniques during the weeks immediately after the mainshocks occurred. EarthQuake-triggered Landslides (EQtLs) mostly consisted of rockfalls and rockslides.

The study deals with the statistical analysis of data collected, on the side of partners, the during the activities of the Caravan Next project, a European social community theatre project oriented on the relationship between the arts and social transformation. The aim is to detect some particular associations between subjective characteristics and various aspects of the Caravan Next activities, from the point of view of the professionals.

The study deals with the statistical analysis of data collected during the activities of the Caravan Next project, a European social community theatre project oriented on the relationship between the arts and social transformation. The aim is to measure the cultural, social and wellbeing impacts of social community theatre experience on participants. In particular, the analysis is based on a sample of 737 citizens (European, seasonal migrants and asylum seekers) who represent 35.51% of people who have actively followed the artistic work.

Microalgal productivity under changing conditions of light intensity and temperature is a crucial parameter for evaluating profitability and sustainability of an outdoor cultivation in cylindrical photobioreactors. The control of the principal outdoor variables, even for the more accurate systems, is subject to a wide number of factors that might influence the measures taken, thus falsifying their correlation with the microalgal growth.

This paper deals with the statistical and geostatistical analysis of drilling parameters for predicting the rock-mass quality ahead of the tunnel face. For this purpose hammer drillings equipped with data loggers (DAC tests) were performed ahead of the tunnel face in order to carry out a preliminary assessment of the rock-mass conditions before the excavation. The study presents an analysis and correlation study between the measured data and the rock mass quality, expressed by the Rock Mass Rating (RMR) index.

This paper deals with the analysis of overbreak in tunnels excavated with the drill-and-blast method. The overbreak phenomenon has many negative impacts on tunnelling organisation and economy and its precise assessment plays a fundamental role in the process of construction optimisation. The study proposes an operative methodology to estimate overbreak volumes and to distinguish so-called technical overbreak, mainly related to drill-and-blast design and execution, from geological overbreak, typically influenced by rock-mass characteristics.

Origanum vulgare L. samples, marketed in different geographic locations, were characterized by their organic and inorganic chemical composition. A total of 35 commercial samples were collected from various sites and analyzed to determine the qualitative and quantitative profile of essential oils, phenolic compounds and some inorganic elements. The variation in the content and composition of the essential oil was assessed by GC and GC-MS analyses, the phenolic fraction was investigated by UPLCVR /PDA, and the inorganic elements were determined by ICP-MS.
