The isotope tracer technique plays a key role in identifying the sources and atmospheric processes affecting pollution. of brown carbon (BrC) at Guangzhou during 2017–2018 were characterized by positive matrix factorization with radiocarbon constraints multiple linear regression analysis. primary emission factors fossil fuel combustion (FF) biomass burning (BB) accounted for 34% 27% dissolved B...

The 3He(3He, 2p)4He and 3H(3H, 2n)4He reactions are studied in a microscopic cluster model. We search for resonances in the 3He+3He and 4He+p+p channels using methods that treat the twoand three-body resonance asymptotics correctly. Our results show that the existence of a low-energy resonance or virtual state, which could influence the 7Be and 8B solar neutrino fluxes, is rather unlikely. Our ...

A two-stage pmcm is proposed for the desii of lowsensitiv-ity constant gain feedback linear regulators. In the f i i stage nominalparameter values are assumed and a model response is obtained. Plantparameter variations are taken into account in the second stage, and asemitivity reduction algorithm is descn’bed in which a performance indexwbicb includes a model-following term...

Radiometric investigation in a rainforest of the Golfo Dulce region of southern Costa Rica has shown the presence of the anthropogenic radionuclides caesium-137, strontium-90 and the plutonium isotopes 238, 239 and 240 along with the naturally occurring radionuclides 7Be, 40K, 238U and 232Th, and respective progenies. 137Cs, 90Sr and Pu can be attributed to global fallout; no other sources coul...

Soil erosion is recognized as one of the main processes of land degradation in agricultural areas. High suspended sediment loads, often generated from eroding agricultural landscapes, are known to degrade downstream environments. Accordingly, there is a need to understand soil erosion dynamics during flood events. Suspended sediment was therefore sampled in the river network and at tile drain o...
