As air is used as the cathode inlet gas, PEM fuel cell with interdigitated flow field can obtain preferable limiting current density, and the optimal power is about 1.4 times as that of the cells with conventional flow field.
Ultimately, the forum reached its strongest agreement around the notion that ovarian reserve (in conjunction with other physiological markers of likely treatment effectiveness) is the most appropriate basis for limiting subsidy, and preferable to limits based upon age or cycle number.
Hal S. Scott, a professor in Harvard Law School, said it would be preferable to limit short-term borrowings by banks, since that is more vulnerable to bank runs.
In this context, it is preferable to limit the number of cores employed, idling the rest of them so that the OS can move these cores into an energy-saving state (C-state) that yields a significant reduction of dynamic power.
Therefore, it is preferable to limit the fluxes of these reactions to biologically reasonable values.
Implementing genomic evaluations was the most efficient approach when major expenditure was possible, whereas increasing phenotypes was preferable when limited resources were available.
Therefore, the SF model is preferable when limited data is available, whereas the LBL and LBLX models are preferable when high temporal resolution is desired and more detailed data is available.
Faster internet connections meant that streaming music became not just possible but preferable: smartphones had limited storage, so it was simpler not to keep music files on the device itself.
Some property owners believe a seven-story limit is preferable.
"No credible evidence has yet been published to show why a UK population of 70 million is preferable to a population limit of 50, 60 or 80million - or any other number," says the Migration Observatory think-tank based at Oxford University.
