The phrase "and at a weaker" is not complete and lacks context, making it difficult to determine its correctness in written English.
It could potentially be used in a context discussing comparisons or contrasts, particularly in relation to strength or effectiveness.
Example: "The results were promising, but the effects were more pronounced in the stronger group and at a weaker level in the control group."
Alternatives: "and at a lesser" or "and at a diminished".
Considering the other serotonergic receptors, aripiprazole behaved as an inverse agonist at 5-HT2BRs, as a partial agonist at high intrinsic activity at 5-HT2CRs, an antagonistist at 5-HT6Rs, asd as a weak partial agonist at 5-HT7Rs [ 36].
The service sectors in China (pdf) and Britain expand at a weaker pace.
However, production increased more slowly than in July, and factories added jobs at a weaker rate.
VvSUC11 and VvSUC12 are detected in all organs but at a weaker level and VvSUT2 is the less expressed sucrose transporter being only weakly detected in young leaves and roots.
Raman spectra of these inclusions exhibit the characteristic resonance of S3 − and S2 − multiatomic ions (a very strong band at 548 cm−1 with weak bands at 258 and 290 cm−1, and a weak band at 588 cm−1, respectively) (Fig. 4f), and appear identical to the Raman signature of lazurite (Na8[Al6O24]Sn) [11, 16], the mineral responsible for the blue color of the semi-precious stone lapis lazuli.
In addition, the besides third exothermic peak that corresponded to the dehydration and carbonization derives two peaks at 214 and 236 °C, and a weak peak at 170 °C can be observed, implying that the addition of thiourea can advance the dehydration and carbonization process.
Raman spectra were recorded on several samples and showed an intense peak at 197 cm–1 and a weaker peak at 138 correspondingnding to Raman active A1g and Eg symmetry phonons of the bulk hexagonal 1T-TiSe2, respectively.
Pilots feared for their careers and were infuriated that their counterparts at a weaker airline might supplant them -- especially since, they reckoned, management was paying for the deal with the very money it had saved on pilot wages.
The difference spectrum shows a strong peak at 1070 cm−1 and a weaker peak at 2080 cm−1.
In agreement with the spectra in Fig. 3 ▸(c), the difference spectrum shows a strong peak at 1070 cm−1 and a weaker peak at 2080 cm−1.
