"maintained at this level" is grammatically correct and can be used in written English.
It is often used to describe the consistent or ongoing state of something being at a particular level, quality, or standard. Example: The company's profits have been maintained at this level for the past five years.
The temperature was gradually increased to 800 1000 °C over a period of 60 120 min and maintained at this level for about 30 min.
For all sows, litter size suckled was standardized to 10 piglets on day 1 of lactation, and maintained at this level until weaning on day 26 post-partum.
Time-activity curves (TACs) demonstrated that the radioactivity of [11C]AZT in both tumors plateaued at 10 min and was maintained at this level until 60 min after injection (Fig. 3a).
In contrast, the highest bacteriocin activity of BLS was measured at 16 h and maintained at this level to 24 h in MRS, pH 6.2 at 37 °C (Fig. 3d).
According to Fig. 2, this seems to have been reached and even exceeded, since the prevalence of VAP, as estimated by the surveys, was as high as 28% of the ventilated patients in 2010, reached 11.3% in 2014 and was maintained at this level for the next 2 years.
Results: Body temperature increased by a mean of 0.16 degrees Celsius (SD 0.35, p < 0.001) at T2, was maintained at this level at T3 and had returned to pre-immersion resting values at T4. Regression analysis demonstrated that the temperature response was not related to the water temperature (T2 r = –0.01, p = 0.9; T3 r = –0.02, p = 0.9; T4 r = 0.03, p = 0.8).
The gradually increasing photocatalytic activity can reach to an up limit in about 5 photocatalytic cycles and maintain at this level.
Expression of two other oncogenes (G-protein coupled receptor 25 and chemokine-like receptor 1) was up-regulated from non-expression level in control cells to a level 3 fold higher than the cutoff expression level at the early infection stage and maintained at this high level of expression throughout the entire transformation process.
About 4 hours after hormone application, a large increase in clusterin mRNA levels was detectable and was maintained at this high level even at 96 hours after treatment.
The activity of FLPL is greatly reduced at 37°C and maintained at this reduced level at 20°C 25°C, temperatures permissive for parasite development in the mosquito.
They were maintained at this moisture level until the start of the water-withholding treatment based on gravimetric measurements and adjustment of the irrigation schedule (week 4).
