What this implies is that L2 listening strategy instruction may not improve learners' L2 listening proficiency in the absence of certain prerequisites, particularly when L2 linguistic knowledge has yet to reach an adequate level that might allow L2 listening strategies to be applied.
The paracrine dependence of precursors on axons for survival provides a mechanism for matching precursor cell number to axons in embryonic nerves, while the ability of Schwann cells to survive in the absence of axons is an absolute prerequisite for nerve repair following injury.
Origins, in other words, showed absence of thinking as an indispensable prerequisite for the success of Nazi ideology.
The following criteria were used to select the compounds in the training and test set: successful generation of SMILES by the SMILES generation algorithm; absence of non-organic elements (a prerequisite of the ADMET Predictor); efflux ratio ≥0.7; coefficient of variation for replicates ≤50% and elimination of censored data.
This scenario has implications for how developmental and phenotypic plasticity of a lineage interact in the absence of ecological variability; an underlined prerequisite to studies of phenotypic plasticity [ 122, 123].
By means of a quality control check that is commonly performed at the beginning of studies, ASC were frequently analysed for CD34-negativity, since the absence of this marker is a prerequisite to meet the minimal criteria for multipotent mesenchymal stromal cells (Refs 25, 47).
Although carbonate super-saturation, warm waters and absence of clastic input were all prerequisites for the development of microbial limestone in the >12000 km2 Luolou Platform of the Nanpanjiang Basin19, how to switch swiftly from acidic to alkaline and CaCO3 super-saturated waters remains open.
He added, "The absence of competition seems to be a prerequisite for excellence in most endeavors, contrary to received wisdom".
Our model results also support the idea that the absence of strong grazing pressure is a prerequisite to bloom formation for both non-inducible and toxic strains of Pfiesteria.
However, the absence of implant-related complications is a prerequisite for good long-term outcome.
This may not be surprising, as absence of methylation is not the only prerequisite for a gene to be expressed.
