Sentence examples for whereby concentrations from inspiring English sources

A dilution effect is observed whereby concentrations of various elements are significantly and strongly negatively correlated with quartz.

Quantification is based on the principle of stable isotope dilution, whereby concentrations are derived from the response ratio of each acylcarnitine species to that of a deuterium-labeled acylcarnitine standard.

Static imaging, in order to investigate the effects of GBCA on image-based activity concentration, was performed in order to control all parameters except GBCA concentration rather than the use of a dynamic phantom whereby concentrations of both GBCA and PET radiotracer are both changing rapidly.

The 6 h pulse of MK-8776 waselecteded above as it is consistent with the short half-life in patient plasma whereby concentrations above 1 μmol/L are only maintained for 6 h [ 8].

Interestingly, many of the proteins that were differentially detected among Line A and B birds (Figures 4 7) showed a similar pattern whereby concentration was reduced in Line A birds infected with either E. acervulina or maxima.

What is important from the standpoint of human exposure is that, unlike vehicular emissions, which by nature have a strong local character whereby concentration decreases rapidly with increasing distance from their source, secondary formation of UFPs is more regional in nature, which implies a more uniform population exposure to UFPs generated by this mechanism.

Another layer of complexity of TGFβ-signalling is that TGFβ affects EC in a concentration-dependent manner, whereby low concentrations promote whereas higher inhibit angiogenesis (22, 23).

Indeed, Aβ also shows a comparable concentration-dependent bimodal action, whereby picomolar concentrations activate α7-nAChR and increase its expression [54], whereas nanomolar concentrations block receptor activity [75] [76].

A general consensus thus exists whereby lower concentrations of the hormone can promote root extension, while higher concentrations are inhibitory for growth (Jackson et al. 1981; Jackson 1991), so underlining the biphasic action of ethylene in regulating many aspects of vegetative growth (Pierik et al. 2006).

Transient HNE exposure produced a similar curve for the inhibition of IL-6 synthesis as compared to continuous exposure whereby lower concentrations of HNE (0.01−5 μM) afforded minimal inhibition of expression, and higher concentrations (10 μM or higher) produced a steep decline in levels of IL-6.

The addition of material by runoff from the land is adjusted by reactions within the ocean waters or between the ocean waters and sedimentary materials whereby the concentrations of the individual elements remain essentially constant.
