However, telling someone's precise age at a glance without any reference information is essentially difficult even for humans [10].
Hence, dealing with SAR data is essentially difficult because samples from the tail of the distribution will have a strong influence on parameter estimation, and bias will be introduced if we decline the weights of them [6].
It is essentially difficult to deny that interventions to facilitate physical and psychological health would be enhanced if they were founded on a thorough systematic understanding of the way in which psychological factors relate to adaptive and maladaptive outcomes.
Bob Venero, a Bayport resident who runs a children's foundation that bears his name, said he created the virtual offices at Good Samaritan's pediatric ward "to try to make a child's hospital stay, which is essentially a difficult time for all involved, just a little more bearable for those kids and their families".
Even when land is made available, convincing some refugees to plant food and essentially settle is difficult.
The situation is very difficult, essentially because the DR is a poor, but robust country, whereas Haiti is a complete economic basket case strongly dependent on foreign aid.
He essentially foists the difficult work of mechanics onto his team and acts more as a quality vet, which most teams grow to despise.
Romney said in a GOP debate in January that "self-deportation" -- essentially making life difficult for undocumented immigrants until they decide to leave -- would be the best policy for lowering the number of people in the country without authorization.
Since the transition from temperature change to OPL is essentially linear, but difficult to accurately solve [ 11], the modeled (maximum temperature change, Eq. (10)) and experimental (maximum OPL change, Eq. (6)) results were compared after normalization (Fig. 3).
However, accurate determination of the appropriate angle correction for velocity is difficult, essentially because this angle can be measured only in a two-dimensional plane, which therefore disregards the angle in the third dimension of the heart.
Although there is increasing evidence that arsenic exposure alters methylation levels in both global DNA and promoters of some genes, the current available studies are essentially descriptive and difficult to interpret because of the complexity of the study populations and limited information provided in the reports.
