In this paper, we consider reaction-diffusion epidemic models with mass action or standard incidence mechanism and study the impact of limiting population movement on disease transmissions.We set either the dispersal rate of the susceptible or infected people to Ski de fond - Homme - Vetements - Chandail zero and study the corresponding degenerate
Background: Fine particulate matter (PM2.5) is one of the most common outdoor air pollutants, and secondhand smoking (SHS) is an important source of inhalable indoor air pollution.Previous studies were controversial and inconsistent about PM2.5 and SHS air pollutants on neonatal birth weight outcomes, and no studies assessed the potential interacti
The bias voltage-accelerated plasma was developed to investigate the in-situ wetting between liquid tin (Sn) and capillary porous system (CPS).Low wetting temperature was achieved in comparison to traditional static method.During the plasma irradiation, the correlation among temperature step, optical emission spectrum of Sn atom and wetting phenome
