Mixed refrigerant processes were originally developed for the liquefaction of natural gas. There has, however, been considerable interest in academia as well as in industry in developing mixed refrigerant processes for the liquefaction of nitrogen and air [1, 2, 22–24, 29, 30, 45–47, 84]....
Cooling and liquefaction of air and its constituents Mixed refrigerant processes were originally developed for the liquefaction of natural gas.

Air kerma is defined in air, the constituents and the amounts of which are determined experimentally with some uncertainties. The inherent uncertainty of air kerma in a photon beam stemming from the uncertainties of atomic weights and composition data in air was evaluated as a function of photon...
The House passed its budget plan along party lines. But the matter is not a done deal as Republican lawmakers face a bitter fight between chambers, resistance from unified Democrats and angry constituents. Aneeta Mathur-Ashton Feb. 26, 2025 What’s Next for the House ...

Air entrainment is very sensitive to the concrete mix constituents, mixing, temperature, transport, pumping etc. and achieving consistent air content from batch to batch can be difficult if these parameters are not well controlled. Air-entraining admixtures are surfactants that change the surface tensi...
Recent time series studies have indicated that daily mortality and morbidity are associated with particulate matters. However, about the relative effects and its seasonal patterns of fine particulate matter constituents is particularly limited in developing Asian countries. In this study, we examined the...
