Construction and Civil Infrastructures Monitoring Systems

Civil infrastructures are usually monitored through its whole life cycle. SHM (Structural Health Monitoring) technologies enable the estimation of the structural state and detection of structural change that affects the performance of a structure. Two discriminating factors in SHM are the time-scale of the change (how quickly the state changes) and the severity of the change. These factors ...

Cyanobacteria successfully monitored and controlled by using ultrasound

Cyanobacteria- also known as blue-green algae- cause problems when blooming in lakes, ponds and reservoirs. Mainly due to the production of toxins, cyanobacteria cause fish kill and the death of other aquatic animals. They also affect human beings, causing paralysis and skin irritation, and they are even thought to be related to the occurrence of liver cancer. In drinking water reservoirs, the ...

Automotive catalytic converters and environmental pollution: role of the platinum group elements in the redox reactions and free radicals production

The concentrations of Platinum Group Elements (PGE) (Pt, Rh, Pd and Ir) in the atmosphere of urban areas have been progressively increased as a consequence of their release from the automotive catalytic converters and their adsorption in the particulate material. The PGEs catalytic activity is therefore extended also outside the vehicle converters. In the environment, PGEs come in contact with ...
