Sentence examples for variability in concentration from inspiring English sources
The findings suggest that variability in concentration of naturally occurring methane is likely greater than believed, particularly in valley settings where saline groundwater systems interact — through natural cracks in the deep rock — with local freshwater systems, said Barth-Naftilan.
Catchments that show little variability in concentration with discharge (or "chemostatic behavior") likely have average fluid residence times that exceed the time required to reach chemical equilibrium.
Overall there were very few statistical differences (P > 0.05) between inflow and outflow concentrations due to their nascent variability in concentration between seasons, hydrology and runoff volume.
An airborne material released from a surface indoors would be expected to result in a high degree of variability in concentration.
Consequently, estimated microorganism concentrations may be biased and only a fraction of the variability that is observed in temporally distributed concentration estimates is due to variability in concentration itself.
The water quality pertaining to 16 parameters was analyzed for the period February, 2007 to May, 2010 in RUA, which exhibits contamination above the prescribed limit and shows variability in concentration during pre- and post-monsoon periods with reference to BOD, TSS, TDS, PTC and CTC.
There was also spatial variability in concentrations of metal(loids) in precipitates between drains.
Additionally, we assessed how well meteorological variables and traffic density patterns appeared to explain hour-to-hour and day-to-day variability in concentrations.
The calibrated simulations reproduced the general large-scale evolution of the plume, but did not reproduce the observed small-scale spatial and temporal variability in concentrations.
Regression analyses between logarithmically transformed meteorological variables and hourly CO2 concentrations revealed that during the day-time, explained the greatest amount of variability in concentrations over turf, whereas wind speed explained the greatest amount of variability over desert.
We identified patterns of temporal and spatial (longitudinal) variability in concentrations of conservative (chloride and isotopes of water) and reactive solutes (inorganic-N, soluble reactive phosphorous, sulfate-S, dissolved organic carbon (DOC) and nitrogen, and fecal indicator bacteria).
