The monumental complex of Maredolce (Palermo) includes an Arab‐Norman castle that stands on the banks of an artificial lake carved out of the calcarenitic rock that rests on impermeable clays. The lake was originally filled with water, thanks to the channelling of a spring. Over time, the lowering of the water table and the high hydraulic permeability of the calcarenites have caused the lake to dry up. A project to renovate the monumental complex has recently been launched. It also provides the study of a possible restoration of the original conditions of the lake. To this end, a multidisciplinary geophysical study was carried out to investigate the geotechnical conditions of permeability of the land outcropping and provides valid technical solutions for waterproofing the bottom of the lake. For this purpose, a joint interpretation was performed using data acquired with different geophysical techniques, such as seismic refraction tomography, electrical resistivity and induced polarization tomography, multichannel analysis of surface waves and horizontal‐to‐vertical spectral ratio of environmental vibration recording. Joint interpretation, supported by cluster analysis techniques, allowed the reconstruction of the geophysical and geotechnical model of the subsoil of the ancient lake, helpful to suggest appropriate techniques for waterproofing the bottom of the lake.

Geophysical methods (in particular ERT technique) constitute an excellent tool for the detection of buried\ud cavities. However the integration approach of e different geophysical methods could minimize the ambiguity of\ud geophysical interpretation of the buried cavity. The technique of electrical tomography has been joined to the\ud technique of seismic refraction tomography in order to obtain more robust interpretations. Many tests have been\ud carried out using synthetic data and experimental ones. It was finally used a statistical approach based on cluster\ud analysis of the P-wave velocity, the density of the seismic rays and the electrical resistivity of the synthetic and\ud experimental models. Distribution maps of the cluster in multi-space were built, allowing to better define and\ud interpret the anomalies of the subsoil

This study has explored the valence of sibship that may empower the self-esteem of children with asthma at the interpersonal, environmental control competence, emotionality management, and body-image levels. It has been assumed that the relationship between siblings may have a moderating effect on the negative impact that asthma has on child’s development. Seventy children suffering from chronic asthma have been involved: 40 children with siblings (experimental group) and 30 sibling-free children (control group). The children with asthma have exhibited higher levels of self-esteem in comparison with the sibling-free children. The results of the study, at the clinical significance level, highlight how meaningful could be the involvement of healthy siblings to support the development, and to ease the compliance of children suffering from asthma. The outcomes have confirmed the supportive valence of sibship for the self-esteem of the children with asthma.
