The unsteady movement of viruses outside buildings is simulated by the method of large eddy simulation (LES). The virus source originated in a room with infective patients is described by the non-linear population dynamic model of virus infection. Considering the indoor virus emitting outside from windows, the emitting viruses are moving with airflow around buildings. The Smagorinsky-Lilly model is...
The unsteady development of pathogens in a room with infective patients is simulated by the non-linear population dynamic model of virus infection. Assuming the indoor pathogen emitting outside from windows, the emitting pathogens are taken as a source for simulating the transmission of pathogen around buildings with airflow. The three-dimensional Reynolds-averaged Navier-Stokes equations coupled...
The results of the grapevine clonal selection carried out in Tuscany in the last seven years not only provided evidence of a high concentration of viral infections, but also showed that the sanitary status of the variety Aleatico is extremely worrying. The sanitary tests conducted on 172 plants, selected in the Elba Isle, on the hills around Lucca and in Maremma region showed a critical phytovirological...
