The phrase "achieved at approximately" is correct and usable in written English.
It can be used when discussing results or outcomes that were reached around a certain time or measurement, indicating an estimate rather than an exact figure.
Example: "The project was completed and the goals were achieved at approximately 5 PM."
Alternatives: "reached at about" or "attained around".
Perfect transparency was achieved at approximately 460 nm.
The results from the testing of tensile specimens with a central hole as well as from punch tests show that equivalent strains of more than 0.8 can be achieved at approximately constant stress triaxialities to fracture of about 0.3 and 0.66, respectively.
Those who hadn't continued in physics or a physics-related field achieved at approximately half the level of 3.5 years earlier.
Figure10 shows the variation of the feature K2 against SNR, where it is observed that successful classification can be achieved at approximately 7 dB.
For the bare solar cell, the peak EQE value of 59% was achieved at approximately 650 nm, but the value declined beyond a wavelength of 900 nm because of reduced absorption at long wavelengths and low minority carrier diffusion lengths.
The fracture was dynamised at 2 months and union was achieved at approximately 4 months (e and f) when the external fixator was removed and the limb supported by a weightbearing cast.
In Fig. 5, it is observed that increasing of lime content causes significant improvement in compressive strength of the soil at in all of the pozzolan contents, and the maximum strength is achieved at 5% lime approximately.
The recovery was also rapid with 100% recovery achieved at lignosulfonate concentration approximately 0.3 g/L as Klason lignin.
BBB opening was achieved predictably at approximately 50% power at which cavitation was observed during a ramp test.
The results indicate that for a standard 50-μl PCR product highly efficient capture is achieved already at approximately 100 μg of beads for all products up to 1.3 kb, but for a highly optimised amplification reaction a higher amount of beads may be necessary (data not shown).
The value of the fixed parameter C a, max set to 500 mM, so that the maximal Na+ concentration achieved at low flows is approximately 800 mM, associated with an approximately 5-fold magnification of the input concentration of c d (0) = 150 mM.
