The primary mission objective of analysing the composition of the comet was designed to be achievable within this timeframe but landing on its side has made things difficult.
These technologies promise to greatly speed progress toward introduction of crop and livestock genotypes with valuable new traits not achievable in reasonable timeframes using conventional breeding techniques.
But it's also important to make sure your goals are reasonable and achievable within realistic timeframes.
This means that, apart from retaining numerical accuracy, a much more physically accurate solution is achievable within a short timeframe.
For Hinrikus, he had hopes that they'd come to a good conclusion, "with a clear plan of what's achievable in a short timeframe.
The INDC submitted by the Obama administration appears to have been based on its determination of what was achievable within a given timeframe under the Clean Air Act.
All these actions, in contrast to the vague political statements made at international meetings, will be concrete, specific and achievable in a reasonable timeframe: they might, for example, involve stopping a destructive industrial project, protecting the habitat of an endangered species, changing or passing a law, or reintroducing a population of animals or plants.
The experiments suggested below are achievable in a reasonable timeframe of about three months if the authors have the tools to manipulate those neurons with cellular resolution (all three drivers are much more broadly expressed so the observed behavioural effects, if any, could be secondary to interfering with all those other neurons).
Despite technical challenges getting cars on the road by 2020, Senior Manager of Technology Planning at Nissan Andy Christensen, said "The timeframe is challenging, but we believe achievable".
This timeframe leads to strategies that are demonstrably achievable within such a timeframe and a potential reluctance to commit resources over time to difficult and complex issues.
