Since the last decade, numerous free and open-source software (FOSS) has been developed: this new approach, thanks to its quick update and its affordability, has guaranteed the employment of FOSS both by public and private bodies. In the field of open tools, the development of geographic software (GFOSS) became particularly relevant, whose distribution increased enormously and whose innovations are constantly...

It is well known that climatic factors can influence the degradation of rocks in different geographic environments, thus affecting the durability of natural construction materials. Research has been carried out to assess the current state of natural degradation of an Oligocene-Miocene lithic greywacke occurring without appreciable lithological and mineralogical variations from, NW to SE in Tuscany (northern...

The fragmentation process of the falling blocks is a key aspect in the study and the simulation of rockfall phenomenon. The single blocs can generate fragments, deviating their trajectory, modifying their energy. The present research describes an application of a fractal fragmentation model on a real study case and identifies the main issues that can rise. A multi-objective procedure to define model parameters...

Mechanical behaviour of clastic formations at shallow – medium depths which bear hydrocarbon reservoirs could exhibit an important non-linear influence of the strain on the formation stiffness during depletion. Particularly in the early reservoir production stage, characterized by high uncertainty and little ground movement data for back-analysis, reliable determination of formation stiffness at...

Road tunnels are high-risk environments, especially in the event of a fire. These environments are at a high technological level, as they are equipped, as required by the regulations, with complex systems to prevent accidents and reduce the severity of the consequences. The safety of a tunnel depends on the reliability of equipments and their electrical supply circuits. Detection of faults in electrical...

The residual presence of critical components (e.g. Asbestos Containing Materials – ACMs) still represents one of the main criticalities for the Occupational Safety and Health – OS&H in many large public facilities. The very first step for an effective Risk Assessment and Management is obviously a clear definition of the different approaches, complying with the Italian general and special OS&H...

Indoor Air Quality (IAQ) is related to human health and well-being since people spend most of their working and free time in interior spaces. As stated by the World Health Organization (WHO), once complying with normative Occupational Safety and Health (OS&H) limits, more elevated standards of air quality both in productive and non-industrial workplaces should be guaranteed. In this case study –...
