We began by spiking the lowest concentration that was consistently positive at the qPCR step (based on its standard curve) into each procedural step working backwards (i.e., extraction, secondary concentration, primary concentration), which established a concentration that was detectable following losses of the pathogen from processing.

For standardisation, each grid cell value in the primary concentration map was transformed using a normalized difference index: C =, left( {X^{prime } - X} right)/, left( {X^{prime } + X} right) (1 where X′ is the observed concentration and X is the WHO maximum desirable concentration.
The RETRACK [13] freight train operation put down markers as to what could be achieved operating a fully privatized international wagonload/wagon group service between two primary concentration points with traffic assembled and dispatched between these.
The original Shibaura company, formed in 1875, grew out of inventor Tanaka Hisashige's factory, with primary concentration on manufacturing engines for ocean vessels.
This format is called 'iLAMP-nanoprobe' method and can be an appropriate alternative for real-time iPCR, which is used for quantification or determination of the primary concentration of target protein.
Debnath et al. reported the removal of an anionic organic dye (Congo red) using chemically synthesized Fe2O3 NPs as adsorbent and effect of pH, adsorbent dosage, temperature, adsorption time and primary concentration on adsorption was examined [16].
The optimal conditions of xylene elimination was obtained in primary concentration of 100 mg/l, adsorbent dosage of 2000 mg/l, contact time of 20 min, and pH 8.
The effect of main factors and important interaction obtained by the software in designing the experiment showed that Prob ˃ F was less than 0.05 for all main factors and the interaction between xylene's primary concentration and SWCNT-MN nanoadosagents dosage.
Scavenging concentration for 50% of DPPH free radical (IC50) was calculated from logarithmic regression equation obtained from the values of at least five dilutions of the primary concentration.
