The phrase "a poor efficiency of" is correct and usable in written English.
It can be used when discussing the effectiveness or performance of a process, system, or method that is not meeting expectations.
Example: "The project suffered from a poor efficiency of resource allocation, leading to delays and increased costs."
Alternatives: "low efficiency of" or "inefficient performance of".
As a result, the conversion rate is low leading to a poor efficiency of the process.
The geostatic stress, coal mine gas and disturbances produced by external loading can undermine the stability of a borehole and cause the borehole to collapse in a soft coal seam, which results in a poor efficiency of drilling long boreholes and draining gas in a soft coal seam.
If alpha is too small, the channel length will be overestimated, resulting in a poor efficiency of the estimator.
That could be due to a poor efficiency of citrullination by PAD enzyme in vitro as recently described [ 27].
A power conversion efficiency of 2.19% was achieved for the DSSC with ZNRs/ZNPs, through back-illumination, which is higher than that of the cell with only ZNPs (1.80%); the DSSC with bare ZNRs showed a very poor efficiency of 0.90%.
In addition, as a PIP1 member, the poor efficiency of HbPIP1 1 was also observed [ 26].
Recently, the relatively poor efficiency of a bulk-heterojunction OPV has been improved considerably (>10%) in a tandem cell configuration, albeit at the expense of using four different organic materials.
Although the desire to make therapeutically relevant complex proteins with elaborate human-type glycans is a major goal, the relatively poor efficiency of the N-glycosylation process of foreign proteins in E. coli remains a hindrance for industry take-up.
Although the value of this product is comparable to that representing breakeven for magnetic fusion, laser fusion requires a larger value to overcome the rather poor efficiency of existing lasers.
Furthermore, even if it were possible to produce a cysteine mutant that retained activity, the poor efficiency of polymer conjugation to the thiol group made it impossible to obtain the desired product.
By a thermodynamic evaluation of the different reaction kinetics, the poor efficiency of the catalyst in promoting the carbon gasification by CO2 reaction has been assessed.
