The phrase "adequate concentrations" is correct and usable in written English.
It can be used in contexts where you are discussing the sufficient levels of a substance or element, often in scientific or technical writing.
Example: "In order to achieve the desired reaction, it is essential to maintain adequate concentrations of the reactants."
Alternatives: "sufficient levels" or "appropriate amounts".
(b) Multilayer (six) striped patchy shell made by coalescence of six drops with adequate concentrations of PE particles.
Conversely, H2S of adequate concentrations would favor the removal of incoming NH3.
These approaches have been limited by lack of specificity, safety concerns, and a failure to achieve adequate concentrations of delivered compounds to sufficient volumes of brain tissue10,11.
Red wines made from interspecific hybrid cultivars are often low in tannins – even when the grapes have adequate concentrations at harvest.
All the diets had adequate concentrations of fibre (NDF, ADF, ADL, hemicellulose and cellulose), organic matter and metabolizable energy.
We also demonstrate that a multilayer patchy capsule can be made by subsequent addition of material, that is, a series of coalescence of new drops with adequate concentrations of particles, resulting in a final capsule as presented in Fig. 7b.
The serum level of inorganic phosphorus was lower in non-supplemented animals, although it was within adequate concentrations for all treatments.
Nevertheless, large doses are required in order to achieve adequate concentrations at the target site due to the poor solubility of PZQ and its significant first pass metabolism.
Separations processes, which are critical for obtaining the desired product purities are covered next, followed by process engineering and control, which are essential for obtaining the desired products at adequate concentrations in a cost effective manner.
In conclusion, OptiPhos phytase may improve the digestibility of AA and energy if dietary P supply is inadequate, whereas in diets containing adequate concentrations of P, no effect of phytase on the digestibility of AA and energy was observed.
Adequate concentrations were associated with small age (p = 0.048).
