Engine manufacturers, working with airlines and aircraft manufacturers, must ensure we have the best information on the effect of ash on engines, potentially increasing the threshold of ash concentration that engines can tolerate.
Moreover, the threshold of gold concentration for Shewanella to produce Au@NPs is reported here for the first time.
The threshold of ethylene concentration affecting fry darkening is lower than 0.4 μl L-1 and is saturated at 4 μl L-1 [[ 85], and references therein].
Thus, the threshold of antibody concentration required for preventing IPD in HIV-infected children may be higher than the ≥0.35 μg/ml putative threshold suggested for the general population of children.
By selecting such a low threshold, we introduced undesirable PCR byproduct in the form of short DNAs (e.g., undigested primers, primer dimers, etc).. Had the threshold of DNA concentration been set higher prior to final pooling and/or a membrane filter been used to further purify the final pooled product, more small fragment DNAs could have been excluded.
However, the authors assume that the threshold of nucleoside concentrations in the urine may not be exactly enough, that the number of nucleosides measured may not be large enough and/or that other specific combinations of nucleosides should be tested.
The threshold of the recognized concentration was recorded as a grade of dysgeusia.
The threshold of D-glucose concentration, 0.6 mM, under which the induction of the maltose operon starts was collected from [ 42] (Additional file 5).
This serendipitous observation led us to examine the threshold of intracellular GSSG concentration ([GSSG]i) that triggers cell death of HT4 neural cells.
In contrast, with CASQ2R33Q mutation, compromised interactions between RyR2 and calsequestrin markedly lower the threshold of luminal Ca2+ concentrations for the termination of SR Ca2+ release.
