In this review, that does not intend to be comprehensive, we summarize the most significant advances in the area, and highlight some of the more important difficulties that must be faced when trying to design biocompatible organometallic catalysts, such us stability, cell uptake, bioorthogonality and toxicity.
More important difficulties preoccupy them.
In the end, what institutions have in common is far more important than difficulties to establish firewalls to maintain privacy and integrity.
They chose to push through because they'd found something to care about, and that's always more important than our difficulties and problems.
Enhanced oil recovery (EOR) is becoming more and more important with the growing difficulties in the extraction of crude oil from oil reservoirs [1, 2].
The finding proved both influential and controversial, but ultimately more important was the very difficulty of establishing a rate at all.
The 'proof of concept' function of this study makes recognition and comparison of overall patterns of difficulty more important than contrast between specific language features in isolation.
On the other hand, management and planning of spare parts supply chain systems become more important due to the difficulty of ensuring spare parts availability while keeping reasonable inventory and transportation costs.
All listening strategies tasks were followed by self-assessment activities in which students were asked to reflect about the listening difficulties they encountered, the strategies they deployed to face such difficulties and, more important, about the effectiveness (or lack of it) of the employed strategies.
Together the members of Team Concordia have fixed washing machines, celebrated birthdays, helped one another though various difficulties and, more important, conducted science — the principal reason we are living here in Antarctica overwinter.
Thus, establishing the POD-based reduced-order FD extrapolating model with fully second-order accuracy for NSIBEs has far more difficulties, but, more important, it is more serviceable, and more challenging than those for the non-stationary Burgers equation and the non-stationary Navier-Stokes equations.
