Furthermore, calculation of the substance concentration as the activity divided by the activity coefficient is rather inaccurate.

Following parameters are defined: odor substance concentration, intensity of odor and hedonism assessment.

For a maximum transfer of substance concentration, an equal flowrate of solvents and solutions is required.

Previous authors have attempted to convert the measured ionised calcium activity to the substance concentration of free calcium.

Units of such kind are commonly used in fields such as physiology to indicate substance concentration, and spectroscopy to express spectral intensity.

Excystment is influenced by changing physicochemical conditions (such as temperature, substance concentration, and pH) inside the alimentary tract.

The main derived quantity in which amount of substance enters into the numerator is amount of substance concentration, 'c'.

It is also called molarity, amount-of-substance concentration, amount concentration, substance concentration, or simply concentration.

Gallstones Gallstones are crystalline formations in the gallbladder due to abnormal substance concentration in bile.

It has been postulated a future diagnostic tool for endometriosis will consist of a panel of several biomarkers, including both substance concentrations and genetic predisposition.

The amount of substance of a solute per volume of solution is known as amount of substance concentration, or molarity for short.

Lake Nasser has good water quality with only small organic substance concentrations, which makes its water a reference point for water quality along the river and its branches.

Of course, given the fact that the regulation is applied at the homogeneous material level, data on substance concentrations needs to be transferred through the supply chain to the final producer.

If the previous data on substance concentration of free Ca 2 + in gall bladder bile are converted back to active molality we find values in the same range as our values.

In Germany, the concentrations of odorants have since the 1870s been defined by "Olfaktometrie", which helps to analyze the human sense of smell using the following parameters: odor substance concentration, intensity of odor, and hedonic assessment.

The spot diameter of the target is much larger than that of the laser, which makes it necessary to make many laser shots at different places of the target, to get the statistical average of the substance concentration within the target spot.

Although considerable variability in ozone is expected from year to year, including in polar regions where depletion is largest, the ozone layer is expected to begin to recover in coming decades due to declining ozone-depleting substance concentrations, assuming full compliance with the Montreal Protocol.

The main derived quantity in which amount of substance enters into the numerator is amount of substance concentration, c. This name is often abbreviated to "amount concentration", except in clinical chemistry where "substance concentration" is the preferred term (to avoid any possible ambiguity with mass concentration).
