Flooding is considered to be one of the most destructive among many natural disasters such that understanding floods and assessing the risks associated to it are becoming more important nowadays. In t...
Isotopocule characterization of N2O dynamics during simulated wastewater treatment under oxic and anoxic conditions
N2O isotopocule ratios wastewater N2O reduction oxic and anoxic condition
2017/4/10
Isotopocule ratios of N2O (d15N, d18O and SP = 15N site preference within the linear N2O molecule) are useful parameters
to identify sources of this greenhouse gas and provide an insight into product...
Constraining the dynamics of volcanic eruptions by characterization of pumice textures
Phlegraean Fields Plinian eruptions vesicle textures magma ascent dynamics
2015/9/10
We have characterized the textures of pumice clasts from Phlegraean Fields to gain insights into the conduit
flow-dynamics of alkaline explosive eruptions. Vesicularities, vesicle number densities, a...
Integrated geophysical and geological investigations applied to sedimentary rock mass characterization
sedimentary rock mass quality stratigraphy seismic refraction tomography ERT
2015/9/1
The Salento Peninsula (south-eastern Italy) is characterized by sedimentary rocks. The carbonatic nature of the
rocks means they are affected by karst phenomena, forming such features as sinkholes, c...
