"We can see the filters are working because the concentrations of black carbon are going down year by year".
Because the concentrations of hydrogen and hydroxide ions in solution can be measured, notably by determining the electrical conductivity of the solution (its ability to carry an electrical current), a quantitative measure of the acidity or alkalinity of the solution is provided.
Because the concentrations of antiepileptic drugs to be expected depend on the patients present during sampling time, a generally high variability will occur.
The main products were glutamate and CO2, because the concentrations of other byproducts (lactate, acetate, and other amino acids) were very low.
Because the concentrations of seroin and of protease inhibitors are also different among the layers [4], the difference in expression patterns may be due to the compositional dissimilarity.
Because the concentrations of 1-ethyl-3- 3-dimethylaminopropyl) carbodiimide (EDC), N-hydroxysuccinimide (NHS), and glucose oxidase significantly affected the immobilization efficiency, these factors were optimized by the Box–Behnken design.
Sericin is water soluble and is released from a silk mat in a fragmented form [8]. Because the concentrations of sericin are different among the layers, the released protein concentration is also different among the layers [9].
The groundwater monitoring data do not clearly indicate that any trace elements were released into local groundwaters from the dredged sediments, because the concentrations of monitoring elements are very low and inconsistent with time.
Note that the sodium concentration does not remain constant after equilibration with halite because the concentrations of other species still increase with continued boiling, thus affecting activity coefficients and the ionic activity product of halite.
The groundwater poses no threat to human health because the concentrations of physico-chemical parameters that can be used to evaluate drinking water quality are within World Health Organisation standard specification.
Because the concentrations of the inorganic ligands are normally much higher than those of the organic ligands, one can use the fraction of free metals determined in seawater without organics to make a reasonable estimate of the value from.
