The phrase "achieved at a specific" is correct and usable in written English.
It can be used when discussing goals, outcomes, or results that are reached within a defined context or timeframe.
Example: "The project milestones were achieved at a specific point in the timeline, ensuring timely delivery."
Alternatives: "attained at a particular" or "reached at a defined".
It is also illustrated that for beds of different particle sizes, a typical bubbling behaviour can be achieved at a specific gas velocity, this velocity coincides with the point of equality in hydrodynamic force ratios Fd/W, Fip/W and Eip/Fd.
Moreover, this means that the maximum random access transport capacity is achieved at a specific spatial density of transmitting nodes.
In common, the maximum transmission capacity is achieved at a specific outage probability in Figures 5 and 6.
Radiolabeling of DOTANOC was achieved at a specific activity of 10 MBq/nmol with a radiochemical purity >98%%.
Reproducibly, >96% radiochemical purity were achieved at a specific activity of 8 MBq 43Sc per nmol DOTANOC.
Radiolabeling of DOTANOC with 152Tb was achieved at a specific activity of 10 MBq/nmol and a radiochemical purity of >98%% as determined by radio-HPLC (Fig. 2).
Systemic factors together with ideas and interests of the participating actors shape the boundaries for agency and what is possible to achieve at a specific moment in time.
The results indicated that a yield of 66.72 % was achieved at a 1.9 specific gravity cut point at an ash content of 7.69 %.
It was observed that the highest activation was achieved at a temperature of 800 °C, the specific surface increased with time but, on the contrary, high loss of matter was observed.
A 193.7 F/g highly specific capacitance was achieved at a current density of 500 mA/g.
It concludes that the Kyoto targets (and their continuation beyond 2010 in specific scenarios) could be achieved at a cost around 1% of GDP through global emissions trading, indicating also that this flexibility mechanism is a more cost-effective instrument for GHG mitigation than meeting the goal domestically without trade.
