The phrase "at medium levels" is correct and usable in written English.
It can be used when discussing quantities, intensities, or degrees that are neither high nor low, but rather in the middle range.
Example: "The experiment showed that the chemical reaction occurred optimally at medium levels of temperature."
Alternatives: "at moderate levels" or "at average levels".
However, at medium levels of the applied stress, both fracture modes were mixed with a certain ratio of each fracture mode depending on the stress level.
Maximum basal area production is observed at medium levels of richness (between 18 and 25 species per ha) and density (between 15 and 30 m2 per ha).
The number of tree species varies between 10 and 30 per ha in the subplots, and maximum basal area production is observed at medium levels of richness (around 22 species per ha).
Maximum basal area production of about 0.75 m2/ha/year is achieved at medium levels of richness (around 20 species per ha) and medium levels of density (around 30 m2/ha basal area) using percentile regression estimates.
Result: already as I write (5 30 a.m., Eastern U.S. time, Tuesday March 15) radiation at medium levels is venting onto nearby regions of Japan, carrying the seeds of cancer and death that have forced the Prime Minister to tell residents to stay indoors.
Allocating transcripts from a single infected cell line to individual genes, those expressed at low levels (4-99 transcriper per million) were found to alternate with genes expressed at medium levels (100-999 transcriper per million), and transcribed genes were interspersed with SVSP genes for which no transcripts were detectable.
He was alone at the piano, singing in a voice that was once a put-on of old and crotchety but has how become legitimately so; he played his spare piano arrangements at medium level and rarely looked directly at the audience.
In this state, the best levels of Z are achieved by r = 10 nm and t = 5 nm, r = 20 nm and t = 10 nm, and the bigger nanoparticles at medium level of t (14 < t < 21 nm).
As an interesting result, Fig. 13 reveals that at medium level of saturation pressure (4 MPa), low level of foaming temperature (80 °C), and low level of foaming time (20 s), changing the amount of other parameters does not have a considerable effect on the cell size of nanocomposite samples.
Figure 4(a) indicated that most of the panelists preferred the color of almond nuts roasted at high level (180°C for 30 minutes); while Figure 4(b) indicated that most panelists preferred the fracturability of almond roasted at medium level (140°C for 17.5 minutes).
A noticeable result that could be obtained from Fig. 8 is the fact that at medium level of nanoclay percentage (i.e., 2 wt %, which is the optimum level), the foam density does not change significantly with various amounts of processing parameters.
