Collecting particles, it argued, would help scientists "understand how the solar system has evolved".
Coniferous trees with needles are more efficient at collecting particles and cloud droplets than leafy trees [30].
PM2.5 concentration was determined gravimetrically by collecting particles on glass fiber filters, whereas the remaining pollutants and comfort variables were measured using a monitoring device.
Virus stocks were generated in MRC5 or HUVEC cells, collecting particles when cytopathic effects were >90%.
The cart has sensors for measuring carbon dioxide and carbon monoxide, instruments for measuring particle color and concentration, and filters for collecting particles for later analysis.
Particle mass concentration and UFP composition were measured by collecting particles on 37-mm Teflon filters (PTFE 2 μm; Gelman Science) and 37-mm precleaned quartz filter (Pallflex Corp).
All the collected particle and waveform data are stored in the onboard large-volume data storage.
After repeating this cycle for a certain length of time, we collect particle data and compute the cosmic ray spectrum.
Table 1 shows the collected particle masses and recovered fractions after extraction from two weekly samples from each sampling location, as well as the chemical analyses.
We collected particle samples between 0800 and 1000 hours on 47 weekdays (Tuesdays and Thursdays), with samples collected for each mode of transportation on approximately one-third of the days.
