HEPA filters of portable air cleaners as a tool for the surveillance of SARS-CoV-2. [PDF]
Abstract Studies about the identification of SARS‐CoV‐2 in indoor aerosols have been conducted in hospital patient rooms and to a lesser extent in nonhealthcare environments. In these studies, people were already infected with SARS‐CoV‐2. However, in the present study, we investigated the presence of SARS‐CoV‐2 in HEPA filters housed in portable air ...

Population origin determines the adaptive potential for the advancement of flowering onset in Lupinus angustifolius L. (Fabaceae). [PDF]
Abstract In the present framework of global warming, it is unclear whether evolutionary adaptation can happen quick enough to preserve the persistence of many species. Specifically, we lack knowledge about the adaptive potential of the different populations in relation to the various constraints that may hamper particular adaptations. There is evidence

Gas-Phase Reaction of trans-2-Methyl-2-butenal with Cl: Kinetics, Gaseous Products, and SOA Formation [PDF]
The gas-phase reaction between trans-2-methyl-2-butenal and chlorine (Cl) atoms has been studied in a simulation chamber at 298 ± 2 K and 760 ± 5 Torr of air under free-NOx conditions. The rate coefficient of this reaction was determined as k = (2.45 ± 0.

Long‐term evolution of cold air pools over the Madrid basin
Cold air pools (CAPs) are identified. CAPs are a common wintertime (NDJ) phenomenon which combines local, synoptic, and large‐scale processes. No long‐term trend was found either in the CAP ocurrence or their strength. Abstract Cold air pools (CAPs) are one of the most severe weather conditions experienced across many basins worldwide, related to ...
