Abstract Background PRV Fa is common in China and causes most of the pseudorabies in the pig industry.A PRV SA215 strain with deleted gE, gI, and TK genes was constructed to develop a commercial attenuated live vaccine.However, the physicochemical properties, growth pattern, penetration kinetics, and morphogenesis of the PRV SA215 and its parental
A procedure to select the controlling factors connected to the slope instability has been defined.It allowed us to assess the landslide susceptibility in the Rio Beiro basin (about 10 km<sup>2</sup>) over the northeastern area of the city of Granada (Spain).Field and remote (Google EarthTM) recognition techniques allowed us to generate
Current methods of euthanizing piglets are raising animal welfare concerns.Our experiment used a novel two-step euthanasia method, using nitrous oxide (N2O) for six minutes and then carbon dioxide (CO2) on compromised 0- to 7-day-old piglets.A commercial euthanasia chamber was modified to deliver two euthanasia treatments: the two-step method using
The chemistry that occurs in interstellar clouds consists read more of both gas-phase processes and reactions on the surfaces of dust grains, the latter particularly on and in water-dominated ice mantles in cold clouds.Some of these processes, especially at low temperature, are very unusual by terrestrial standards.For example, in the gas-phase, tw
Dust is one of the most burdensome hazards found in the environment.It is composed of crushed solids that pose a threat to the health and life of people, machines and machine components.At high concentration levels, it can reduce visibility.All of these earthbath facial wipes negative phenomena occur during the process of underground mining, where
