Sentence examples for substantial deactivation from inspiring English sources
These findings clearly showed that both the DME selectivity and the CO conversion remained essentially constant for the whole test duration, which confirmed that there was no substantial deactivation of the catalyst.
Compared to a baseline state with eyes open in a darkened room, substantial deactivation (average change: 2.9 ± 0.3% BOLD, 22 ± 2.1% CBF) in the occipital cortex was observed when the eyes were closed.
Pt/γ-Al2O3 and Ni/SiO2 Al2O3 catalysts were found to exhibit significant activity and no signs of deactivation over the course of the experiments, while other catalysts such as NiMo/γ-Al2O3 exhibited substantial deactivation.
In general, the major difficulty was to concomitantly reproduce a substantial slower deactivation together with faster recovery in paired-pulse experiments for α3β2γ2 with respect to α1β2γ2 (Figs 3 and 5).
Again, no significant deactivations were found (baseline versus music).
No significant deactivations were found (i.e. noise versus music).
A similar block of steady-state ICl was observed in each case and ICl kinetics showed a substantial acceleration in current deactivation, notable even with 1 mM OAA and again largely independent of membrane voltage.
In particular, such a substantial difference in the slow deactivation components (Fig. 3) potentially represents differences in the opening/closing, desensitization/resensitization and unbinding rates.
HT7 had no significant activation or deactivation.
Most of these metabolites can be considered deactivation products, but a substantial portion of them may readily be decomposed to biologically active substances which could negatively affect ecosystems.
As an initial screen for such channel regulators, the following criteria were used to identify 'hit' pools: 1) they facilitated channel opening by shifting the conductance versus voltage relationship to more negative potentials without evoking substantial channel block, 2) they slowed the deactivation time constant, and 3) the effects reversed with washout.
