Ethnobotanical knowledge in some rural communities of northern Sicily (Palermo, Italy)
An ethnobotanical study was carried out to document the uses of wild plants among some local communities of Sicily (southern Italy). We recorded 48 taxa belonging to 45 genera included in 32 families. 30 taxa are used as medicinal plants, 22 taxa as food and 9 for handicraft use. In comparison with other ethnobotanical studies carried out in Sicily and other Italian territories, some uses of the plants reported by the local population in the study area are peculiarities. The analysis of data shows that the level of traditional knowledge on use of plants in province of Palermo is poor, highlighting a considerably advanced state of cultural erosion. The results of our investigation confirm th…
Analytical and numerical analysis of the atom–field dynamics in non-stationary cavity QED
We study analytically and numerically the dynamics of the quantum non-stationary system composed of a two-level atom interacting with a single mode cavity field whose frequency is rapidly modulated in time (with a small amplitude). We identify modulation laws resulting in qualitatively different dynamical regimes and we present analytical solutions in some simple cases. In particular, we analyse minutely the influence of the field–atom coupling on the photon generation from vacuum via the dynamical Casimir effect.
