Effect of calcium nitrate healing microcapsules on concrete strength and air permeability by Al-Ansari M.

“…It was also found that the addition of microcapsules considerably decreased the samples' air permeability. Although the flexural moduli of samples containing microcapsules were found to be less than those of samples without microcapsules before healing, modulus recovery was reported after 7 d of self-healing.…”

Impact of SARS-CoV-2 on Ambient Air Quality in Northwest China (NWC) by Zaib, Shah

“…AQI improved in all seasons; significant improvement occurred in winter (December to February) and spring (March to May) when lockdowns, industrial closure etc. were at their peak. The proportion of air quality Class I improved by 32.14%, and the number of days with PM2.5, SO2, and NO2 as primary pollutants decreased while they increased for PM10, CO, and O3 in 2020. …”

Numerical simulation of stall development into surge and stall control using air injection in centrifugal compressors by Halawa, Taher

“…Results also showed that during surge, forces on the impeller blades increase to nearly double of its initial value and then decrease again. By using air injection at the vaneless region with different injection angles, it was found that injection with angle of 30° has a good effect on preventing surge and minimizing the pressure fluctuations comparing to other injection angles results. …”
