I wasn't impressed as we rolled out the mixture – it seemed simultaneously greasy and dry, but it was the hottest day of the year.
It should be soft but not sticky – add the extra egg mixture if it seems too dry.
Therefore, because of the scientific uncertainty related to chronic and mixture effects, it seems reasonable to apply the precautionary principle to prevent serious potential harm to humans and animals and to minimize pollution from pharmaceuticals in the environment [ 12].
It is difficult to disentangle the effect of single air pollutants in epidemiologic designs because they are part of complex mixtures, but it seems likely that for cancer risk PM from traffic emissions is most important.
Thin the mixture with water if it seems too thick.
As for President Bush, his attitude toward McCain appears to have been a mixture of bafflement and irritation; it seems likely, on the evidence offered by Heilemann and Halperin, that he wanted Obama to be his successor.
While it is possible that the hepatocyte and kidney cell lines may themselves be a mixture of different cell types, it seems more likely that the tDMPs in these tissues are not fractionally methylated due to cellular heterogeneity.
The <2 μm fraction, on the other hand, was a mixture of various components and it seems likely that one of these components, which was enriched in C, was the main dietary source of B. dimidiatus along with A. elenkinii.
31 Caffeine shows appreciable surface activity in water which is enhanced by the presence of sucrose, 32 however, in view of the entity of the adsorption phenomenon (for 1.0% pure caffeine at 20 °C monitored up to 20 h, it showed a surface tension equal to 70.1 and 68.5 mN/m in mixture with 6.0% sucrose) it seems difficult to attribute a relevant role of caffeine content as a surfactant.
Sometimes the mixture "curdles" This means that it seems to separate out and looks lumpy.
