The U.S. and its P5-plus-1 partners have choosen to work toward this comprehensive trade on a step-by-step basis, which I think is the only practical approach, given the fundamental differences between Iran and the P5-plus-1.
Measurements from Geostationary Orbit (GEO) offer the only practical approach to the observation of diurnal variation from space with the pertinent horizontal resolution.
DeFries et al.[15] concluded that analysis of remotely sensed data is the only practical approach to measure changes in forest area at national and international scales because changes in forest area since the early 1990s can be observed from space with consistency and confidence.
ASAP method may be the only practical approach to obtain chloroplast DNA sequence from rare or small plant samples.
The ASAP method may be the only practical approach for some rare and/or difficult-to-obtain taxa that are not amenable to chloroplast DNA extraction.
Although such preparations are intrinsically very heterogeneous, this is sometimes the only practical approach for obtaining structural data for an unstable complex.
We believe that the EU model approach, despite its limitations, is currently the only practical approach that can properly account for the data structure encountered in the analysis of IVF data with multiple embryo transfer.
The sequencing and analysis of ESTs is for now the only practical approach for large-scale gene discovery and annotation in conifers because their very large genomes are unlikely to be sequenced in the near future.
As miRNAs are small nucleic acids (19 24 nt), antisense inhibition is considered to be the best and possibly the only practical approach for specific pharmacological inhibition of their function [ 31].
Despite the fact that some studies have questioned the reliability of the Verbal Autopsy (VA) approach, where close relatives of the deceased are asked about the signs and symptoms that precede deaths (2, 3), it remains the only practical approach through which to estimate CODs in most resource-poor settings in which the majority of deaths occur outside the formal health system (2, 4– 8).
