Background Fine particulate matter (PM2.5) exposure accelerates atherosclerosis and contains known ovotoxic chemicals. However, effects of exposure to PM2.5 on the finite ovarian follicle pool have hardly been investigated, nor have interactions between ovarian and cardiovascular effects. We hypothesized ...
Accuracy (pooled standard deviation) was better than ±0.2‰ according to analyses of these standards at an injection level of 20 nmol N over the past 3 years. Quality control was also conducted by analyzing laboratory working reference material (3000 m deep sea water from the South China...
The background spectra are dominated by water clusters, NO+, N2+ and O2+ [32, 49]. In addition to direct He metastable Penning ionization of water clusters, Andrade et al. proposed Penning ionization of N2 molecules [32]:He*+N2→He+N2++e− Addition of different gases to the enclosed...
The composition of pure air depends on the particular location, and is variable in its components (e.g., methane, carbon dioxide, water) so “pure” air has no precise meaning. Nevertheless, pure air is commonly considered to be air which is free of dust, aerosols, and reactive gaseous ...
Subsequent skylight spectral irradiance and in-water optical property measurements were used to model the underwater light field as a function of depth, which was then weight- ed by the electrophysiologically determined visual spectral sensitivity of a dominant high Arctic zooplankter...
water-resistive coating can be used to improve the stability of perovskite solar cells; however, the intrinsic vulnerability of perovskites to moisture remains unchanged19. Better moisture stability was observed for a two-dimensional, layered perovskite formed by incorporating phenylethylammonium (C6H5(CH...

To grasp the pollution characteristics and sources of dustfall, in this work, the filtration method was used to determine the insoluble dustfall and water-soluble dustfall in the urban area of Beijing. From our analysis, the influence of the meteorological parameters on dustfall was found, and...
The I-4C OBS is equipped with velocity seismometers in 3 directions (east, north, and vertical), and the continuous waveform data that they record are ground pulsation velocities. To make a more intuitive comparison and analysis between the results of NLNM and the results of NHNM, the measu...
