In order to study the variation law of the maximum explosion pressure and the maximum pressure rise rate of the premixed gas in the flameproof enclosure, three different flameproof enclosures were selected as the test samples, and the explosion was carried out by filling the premixed typical combustible gas in the flameproof enclosure.In the experi
To evaluate transmission dynamics, we exposed 25 bird species to West Nile virus (WNV) by infectious mosquito bite.We monitored viremia titers, clinical outcome, WNV shedding (cloacal and oral), seroconversion, virus persistence in organs, and susceptibility to oral and contact transmission.Passeriform and charadriiform birds were more reservoir co
