During strong earthquakes, base isolated systems (buildings, bridges, strategic facilities, equipment etc.) can impact against the surrounding moat wall because of the deformation of the isolator if the available separation distance is limited. A possible mitigation measure is the interposition of shock-absorbers (bumpers). In this work some of the results of an experimental laboratory campaign are presented.

Stem cell therapy is a regenerative medicine technique consisting in
introducing new cells into a damaged tissue in order to restore it. In this paper we
present our multidisciplinary approach about the possible use of the Human
Mesenchymal Stem Cells in treating heart failure. A multidisciplinary team
composed by biologists, mathematicians, cardiologists and bioengineers was
selected in order to investigate the feasibility of repairing the necrotic tissue
damaged by myocardial infarction by means of Mesenchymal Stem Cells and to

In this work, a preliminary numerical model of the behavior of retro-reflective materials used as envelope coatings on street canyon buildings façades has been tested. Retro-reflective materials have a surface finish that allows to reflect the solar radiation back in the same direction of the incident radiation. In the last years this kind of materials has been studied as buildings envelope coating for their potentials in the reduction of the UHI effect.

Contaminants removal stoked inside low permeability zones of aquifers is one of the most important challenge of groundwater remediation process today. Low permeability layers can be considered persistent secondary sources of contamination because they release pollutants by molecular diffusion after primary source of contamination is reduced, causing long plum tails (Back-Diffusion).

Secondary clarifiers are demanded to separate solids created in activated sludge biological processes to achieve both a clarified effluent and to manage the biological processes itself. Indeed, the biological process may influence the sludge characteristics, and conversely, the settling efficiency of the sedimentation basin plays an important role on the biological process in the activated sludge system. The proposed model represents a tool for better addressing the design and management of activated sludge system in wastewater treatment plants.
