The aim of the research is to identify method and operational references at different scales, urban and territorial, to be applied to territories affected by earthquakes, useful for defining prevention and reconstruction strategies.
In particular, the activity focuses on Accumoli, and takes concrete form in the construction of a pilot program for reconstruction, defining integrated and coordinated reconstruction actions based on resilience of the affected areas.

In turbomachinery applications blade fouling represents a main cause of performance degradation. Among the different techniques currently available, online water washing is one of the most effective in removing deposit from the blades. Since this kind of washing is applied when the machine is close to design conditions, injected droplets are strongly accelerated when they reach the rotor blades and the understanding of their interaction with the blades is not straightforward. Moreover, undesirable phenomena like blades erosion or liquid film formation can occur.

Advances in the use of neuroimaging in combination with A.I., and specifically the use of machine learning techniques, have led to the development of brain-reading technologies which, in the nearby future, could have many applications, such as lie detection, neuromarketing or brain-computer interfaces. Some of these could, in principle, also be used in forensic psychiatry. The application of these methods in forensic psychiatry could, for instance, be helpful to increase the accuracy of risk assessment and to identify possible interventions. This technique could be referred to as ‘A.I.

Caries measurement methods vary considerably in terms of the stages of lesion considered making the comparison problematic among different surveys. In this cross-sectional study, four caries measurement methods, the WHO-DMFT, the International Caries Detection and Assessment System (ICDAS), the Caries Assessment Spectrum and Treatment (CAST), and the Nyvad Criteria were tested in a sample of children. Five-hundred 12-year old children (236 males and 264 females) were examined four times by four calibrated examiners.

Children's injuries are a serious public-health problem, but they could be substantially reduced by proper prevention. According to the literature the best predictor of injuriesis the physical risk taking. In this study we examined preschoolers' and mothers' perceptions of children's physical risk taking. Participants included 203 children (M age = 60 months), their mothers and their teachers.

Late onset of fluid collection surrounding breast implants may represent a serious issue when considering the possibility of breast implant-associated anaplastic large cell lymphoma, a newly recognized type of T-cell malignancy. However, many other factors, including trauma and infections, may be implicated in the formation of non-neoplastic periprosthetic delayed effusions.

Seismic risk assessment of an infrastructure, intended as a system of systems including buildings, lifelines and critical facilities, is typically affected by several sources of uncertainty, classified as aleatory or epistemic. Momentum to this work came from the need not only to properly take into account all these uncertainties, but also to provide the confidence in the estimate and quantify the contribution of the employed models and parameters to the total uncertainty.

Failure of a pipeline carrying gaseous hydrogen can have several effects, some of which can pose a significant threat of harm to people and damage to buildings in its immediate proximity. This paper presents a probabilistic risk assessment procedure for the estimation of damage to people and buildings endangered by high-pressure hydrogen pipeline explosions.

In this investigation, δ13C and δ15N isotope ratios and heavy metal levels were assessed in macroalgae, sediment samples, and benthic species from northern parts of the Persian Gulf and the Gulf of Oman. The highest δ15N values in algal samples (11±0.42), indicative of anthropogenic organic N inputs, were detected in the Sadaf region, whereas the lowest values (3.17 ± 0.12), indicative of anthropogenic inorganic inputs, were detected in the Parvaz region.
