The phrase "a yield of approximately" is correct and usable in written English.
It can be used when discussing the expected output or return from a process, such as in agriculture, finance, or manufacturing.
Example: "The new farming techniques resulted in a yield of approximately 200 bushels per acre."
Alternatives: "an output of roughly" or "a return of about".
The first Soviet test occurred on Aug. 29, 1949, using a plutonium device (known in the West as Joe-1) with a yield of approximately 20 kilotons.
After inducing with IPTG, the expression product was efficiently secreted into the culture medium and shake-flask culturing gave a yield of approximately 5×105 ATU/L (∼60 mg/L).
In several important tests, we showed that the HCA source is capable of producing carbon layers within a realistic disk production environment with a yield of approximately 93% which proved to be comparable to current magnetron sputtered overcoats.
In several important tests, we showed that the Φ-HCA source is capable of producing carbon layers within a realistic disk production environment with a yield of approximately 93%, which proved to be comparable to current industrial technology.
Enhanced L-lactic acid production was achieved at OTRs higher than 0.28 (g-O2/l/h) irrespective of the scale of the bioreactor in question: in the range of 0.003 m3 to 5 moremore than 90 g/l L-lactic acid was produced with a yield of approximately 80%, based on the initial glucose concentration.
As a percentage of APL's recent stock price of $34.50, this dividend works out to a yield of approximately 1.57%.
Approximately 0.5 to 1 mg of h-BN nanosheets could be routinely obtained from 1 g of the bulk h-BN powder; this corresponds to a yield of exfoliation of approximately 1%.
Quality control was performed by instant thin-layer chromatography with a silica gel, which revealed a radiochemical yield of approximately 91 % at a specific activity of 50 MBq/μg.
For example, the HLA-A products with an average yield of approximately 10 mg/L outperformed HLA-B that furnished only approximately 3.2 mg/L.
This study showed that the hydrolysis of cellulose treated with dissolution/precipitation using an ionic liquid produces a glucose yield of approximately 50% at 140 °C in just 5 h.
In this paper we describe the final design of the MiniPlugs and present results from a cosmic ray test, in which a light yield of approximately 100 pe/MIP was obtained, exceeding our design requirements.
