The phrase "a certain decrease in" is correct and usable in written English.
It can be used when discussing a specific but unspecified reduction in quantity, quality, or intensity in various contexts, such as scientific reports or economic analyses.
Example: "The study revealed a certain decrease in the population of the species over the last decade."
Alternatives: "a noticeable reduction in" or "a specific decline in".
Theoretical and simulation results show that the proposed approach gives a certain decrease in bearing amplitudes and forces.
Comparing to the single-phase molten salt heat storage, the two hybrid thermocline heat storage manners with porous fillers lead to a certain decrease in the effective heat storage capacity.
As the dumping site age increased, the consequent increase in pH values caused a certain decrease in metal solubility (Mohan and Gandhimathi 2009).
However, a good cycling stability with a certain decrease in polarization can be observed in the potential window 4.5 1.5 V versus Li+/Li (0.03 0.14 °C rates) certainly due to the benefic effect of the conductive reduced graphene oxide layers.
Incubation of peritoneal macrophages for 48 hours (Fig 4D) did not increase arginase activity, but rather yielded a certain decrease in the specific activity of this enzyme.
In case of the high fat diet, a certain decrease in their number was noted.
Calculations have shown that the hydrogen termination gave rise to certain decrease in bond lengths in graphene in the vicinity of the terminated atoms (Fig. 1b).
Thus, nHAp/PS with different polysaccharides and different nHAp PS ratios 4 1 and 1 1 synthesized by two-step process demonstrate certain decrease in the textural characteristics with increasing content of PS due to filling of inter-particle voids by polymers.
In addition, the results of mechanical tests indicated certain decreases in mechanical properties as the treatment temperature increased in all the three treatment media.
A certain increase (decrease) in CTOT is thus a way to gauge the net gain (loss) of commodity price movements in GDP terms. Figure 2 exhibits cumulative changes in CTOT indices from average levels in 2002 to mid-2011 (the sunset of the super-cycle), August of 2014 (when the sudden plunge of oil prices started) and February of 2015. Figure 2. Extracted from IMF (2015, p.43). 1.
We analyze the case where one is given a set of initial subunit concentrations A0, B0, and C0, and wants to change them to achieve a certain desired decrease in the amount of the target complex.
