System for the non destructive testing of dielectric materials by means of microwave techniques. The sensor is constituted by a narrow band antenna whose resonance frequency depends on permittivity of the media in the region close to the antenna. When the sensor is close to an object, the permittivity of the surface layers of the object itself is determined by the variation of the resonance frequency w.r.t. a vacuum measurement. Thus, we can obtain information about the object structure. Several ...

Works of art cannot be appreciated without light, but light is also one of the most powerful parameters in altering colour and so causing irreversible damage. Therefore, a compromise has to be found that can balance visitor's requirements and object's safety. It is known that the damage increases with the length of exposure and the irradiance. Rather than limiting the time of exposure for each object, it is advisable to monitor the lighting conditions on site. A continuous monitoring program for ...

The increasing awareness of the impact of human activities on the Earth system has lead some authors to introduce a new term for the present geological era, calling it "the Anthropocene Era". The dimension, the spatial and temporal scale of changes due to human activity is unique in the human history. Biomass burning from vegetation fire is one of the major disturbances of natural terrestrial ecosystems: from boreal forests to temperate zones, from tropical savannas to equatorial ...

In the last years the problem of the non invasive monitoring of the environment have gained a great attention and in particular the diagnostic techniques based on fiber optic sensors play an important role. In fact, these sensors have small dimension, low cost, are immune to electromagnetic interference, are suitable for large scale monitoring networks, and are chemically and mechanically compatible with many materials. However, a typical fiber optic sensor permits only a local measurement of ...

Catalytic combustion can be regarded as an intrinsically clean and safe technology which allows a primary air pollution control, since energy is produced with high efficiency burning fuel/air mixtures also outside the flammability limits, at operating temperatures far lower than those of flame combustion and without the instability problems and pollutants (CO, NOx, soot and unburned hydrocarbons) typical of the traditional processes (fig.1). Moreover the catalytic oxidative conversion of natural ...

Nitrogen oxide, carbonaceous particles and policyclic aromatic hydrocarbon produced in combustion processes are among the main responsible of pollution both on global scale, "greenhouse effect", and in the urban areas, effect on human health. A drastic reduction of such emission can be obtained by using a new combustion technology that allows for minimizing the maximum temperature reached during combustion processes by means of high concentration of diluent species, such as nitrogen, water or ...
