The ignition behavior of Ti3Al-based alloy in 220-380 m/s gas flow environment was studied by using friction ignition method.Combined with numerical calculations, the influence of airflow velocity on surface oxygen concentration and oxidation control step was analyzed, and then the influence of airflow velocity on ignition behavior was discussed.Th

Urban constructed water quality treatment (WQT) wetlands are often applied to be integrated with ecological engineered landscaping (EEL) measures for wastewater treatments.This study aims to identify the interrelationships between the hydrological factors and pollutant removal contributions of typical WQT wetlands at each WQT stage, i.e., subsurfac

Measles virus (MV) is a highly contagious respiratory virus responsible for outbreaks associated with significant morbidity and mortality among children and young adults.Although safe and effective measles vaccines are available, the COVID-19 pandemic has resulted in vaccination coverage gaps that may lead to the resurgence of measles when restrict

Modern agriculture relies on the intensive use of chemical inputs including pesticides.Unfortunately, the irrational and often abusive use of pesticides poses a threat to both human health and the environment through residues in foodstuffs and the pollution of the various compartments of the environment, read more in particular both surface and gro
