However, the time, expense, possible selection bias of those undergoing PSG and possible methodological changes over time rendered it unfeasible for epidemiological purposes in a large longitudinal cohort study.
The heater requires ({sim}242mbox{ W}) for bake-out at 300 K. Before commissioning, LTP and MAQRO only require 30 W. Nevertheless, this high power may render it unfeasible to perform a bake out unless the necessary power can temporarily be allocated from the science spacecraft.
Unfortunately, metallic conductors were the only materials available at the time, rendering it unfeasible to build thermoelectric generators with an efficiency of more than about 0.5 percent.
Studies by different scientists have concluded that the rising water demands in the North China Plain make it unfeasible for farmers to continue planting a winter crop.
The camera phone changed all that - making it unfeasible for galleries to stop people taking photographs.
As the previous work, this research was also performed on an FMD dataset that made it unfeasible for FOD material recognition tasks.
The cost of qPCR reagents and the required workload make it unfeasible for regular phenotypic screening.
However, the high cost of the assay makes it unfeasible for the routine mass screening of cervical infections in resource-poor areas of developing countries [ 22].
Historically, animals were tended by hired milkmaids on the summer farm, whereas today these tasks are generally carried out within the family as increasing labour costs during the twentieth century have generally rendered it economically unfeasible to hire personnel for small farms.
Such networks intuitively appear to incur high computational cost, and require the storage of a large number of parameters, which render them unfeasible for deployment in portable devices.
In a joint statement yesterday they said: "The decision came after a careful and thorough evaluation of commercial quotations from engineering, procurement and construction bidders, which showed high capital costs rendering it commercially unfeasible, particularly in the current economic climate prevailing in the energy industry".
