The phrase "a decrease in efficiency" is correct and usable in written English.
It can be used when discussing a reduction in the effectiveness or productivity of a process, system, or individual.
Example: "The recent changes in the workflow have led to a decrease in efficiency, causing delays in project completion."
Alternatives: "a drop in efficiency" or "a decline in efficiency."
Nevertheless, at 50 °C there was a decrease in efficiency.
Due to negative impact of CFB on cash flow of supply chain, it can lead to a decrease in efficiency of supply chain management (SCM).
LBC showed a significant increase in the normalized characteristic path length, suggesting a decrease in efficiency in information access, and altered nodal centralities in the fronto-limbic regions and motor and sensory systems.
The other interesting results are: (1) the current vs. voltage characteristic curve is constituted of three main linear parts, with an optimal zone (4.5 12 V); and (2) the water dissociation threshold voltage was clearly shown (12 V) and coincides with the beginning of a decrease in efficiency.
All SCs showed a high o-PO4 removal efficiency of >98% during P1 (average influent of 1.8 mg P L−1, effluent of 0.04 mg P L−1) and >85% during P2 (average influent of 8.7 mg P L−1, effluent of 0.65 mg P L−1) with a decrease in efficiency only observed over time in the SC that received the highest organic loading rate.
A decrease in efficiency with higher k s values can be noticed.
Nitration of the corrosion inhibitor molecules led to a decrease in inhibition efficiency, while reduction of the nitro group led to an increase in inhibition efficiency.
When the transfection efficiencies are normalized with respect to the molar concentrations of plasmid DNA, a decrease in transfection efficiency with increasing plasmid size was observed in 293T.
Expression of rab9 S21N was accompanied by a decrease in the efficiency of lysosomal enzyme sorting.
For the wetland in this study, increasing the water depth elicited a decrease in hydraulic efficiency.
The eigenvector approach produces the least linearly dependent results, but exhibits a decrease in average efficiency.
