Since the feature of received signal varies with different multipath propagation conditions, an labor-intensive on-site calibration procedure is almost indispensable to decide the optimal scenario-specific threshold for human detection.
This process is labor intensive, relies on subjective interpretation from the operator, and offers limited sensitivity as only mutations above 20% frequency can be reliably detected.
But I have to admit that her later work struck me as not only labor intensive, but on occasion, rather laborious.
These methods are labor intensive, reliant on species-specific reagents (e.g. mAbs and genotyping primers) and particularly for PCR, amplification of the analyte for detection.
This was also extremely labor intensive and, on 6 December 1921, they extracted fetal-calf pancreas with slightly acidic 95%% alcohol, and the extract successfully lowered blood glucose levels.
Additionally, most methods are either costly, labor intensive or rely on infrastructures which are non-existent in developing countries.
Finally, some have pointed out that it is not clear whether cloning research is necessarily more labor intensive than experiments on cells and tissues now done in animals.
Turning a compost pile can be labor intensive and hard on the back.
Each craft is labor intensive, and generally involves hands-on efforts by the artists working alongside the craftsmen.
For a dish that's not especially labor intensive, it ranks high on the flavor scale and tastes fresh, clean and bright: the kind of home-cooked fast food we can all appreciate.
