So some of the hydrocarbons evaporate, and the concentrations of the various compounds change.
The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased.
The quantity transported is determined both by the rapidity with which the blood circulates and the concentrations of gases in blood.
Sodium and chloride are the predominant ions in seawater, and the concentrations of magnesium, calcium, and sulfate ions are also substantial.
The results indicated that an excellentcorrelation existed between the peak areas and the concentrations of impurities.
wherec andx stand for the relative conductance and the concentrations of silver ions, respectively.
Samples were collected intervals to analyze pH, Eh, and the concentrations of ferrous ions.
Samples were collected to analyze pH, Eh, and the concentrations of Fe2+, Fe3+, and Cu2+.
Interspecies electron transfer and the concentrations of electron carriers are crucial for maintaining this mutualistic activity.
The kinds and the concentrations of nano-particles and surfactants are considered as the key parameters.
Soil solutions were extracted and the concentrations of both anions and cations were determined.
