The approach used in the present analysis, based on the selection of four-b events, results in a smaller statistics, but the dependence on the Monte Carlo model is reduced,

Figure 1 (right panel) shows the variations of the

The relative 0, photodissociation frequency is subject to the double effect of the decrease of the effective photodissociation and the absorption cross-section

This paper introduces and appraises the distribution of HgT and MMHg in the solid phase and pore water of sediment cores collected in the Thau lagoon, in order to study the

Since we expect a potential relationship between the shape of the profile and the Chl-a concentration, we an- alyze here a global ocean database of fluorescence profiles

Along with the Passion of Christ and the Last Judgment, the initial moment defined by the Creation then conferred to time an irreversible, linear orientation and to history both a
