7(c) shows that the pollutant concentrations are seasonal, being lowest in the summer season and highest from January to May. SO2 and NO2 concentrations show similar seasonal trends that can be attributed to the decrease in traffic density and industrial emissions during the summer holidays. The...
Air flows in a4-cm-diameter wet pipe at20\deg C and1atm with an average velocity of4m/s in order to dry the surface. The Nusselt number in this case can be determined from Nu50.023Re0.8Pr0.4where Re510,550...

In this paper, we present the ARPALData software, an R package (R Core Team 2020) aimed at retrieving, handling, and analyzing air quality and weather data for the Lombardy region in Northern Italy. Lombardy has approximately 10 million inhabitants and the largest population density in Italy, ...
(Corning) dilution. Once confluent, submerged OM cells were passaged and seeded on coated 24-well transwell inserts at a seeding density of 4 × 104–5 × 104cells and cultured in PneumaCult‐Ex Plus media for 2–4 days with media in both apical and basal chambers. Cells were ...
The invention concerns an improved bactericide applied with a doser on air conditioning conduits. Said bactericide consists of a product in the form of an greenish, odorless aqueous solution with a density ranging between (0.9940 +/- 0.0013) g/ml at 20 DEG C, which is totally soluble in ...
First, universal kriging was used to predict NO2 levels at unmonitored sites, i.e. the women's residences. Then, geographical information system (GIS) data (traffic, i.e. vehicle density and distance to a main road, land use, and altitude) were used to improve predictions with the aid ...
Much effort now focuses on the technology and regulation, but infrastructure density will likely play the biggest role in driving scale once the technology is ready and regulatory reform passes. Here is why: the closer passengers are to a vertiport, the greater their potential tim...
