| Arabidopsis plants were grown on agar containing a complete mineral complement and various concentrations of selenate and sulphate. |
| Dangerous concentrations can be released by agitation of stored liquid manure. |
| At very high concentrations of poly-L-lysine and a large number of attached cells, the membranes rupture due to the adhesion-induced tension. |
| The concentrations of manganese in two samples of surface soil taken from area A were 748 and 629 micrograms per gram, dry weight. |
| To calculate the concentrations of all microspecies at any pH we need to solve the following system of equations. |
| Different concentrations of ground water nitrate were obtained by drilling irrigation wells into two aquifers. |
