But, when oxygen began to make inroads, even in concentrations far lower than present levels, it found the iron atoms, bonded itself to them, and pulled them to the seafloor.
The Australian scientists may also have discovered how these highly spiced potatoes were allowed to leave the kitchen: they tested 49 people and found that about 20percentt of them could not detect rotundone at all, even at concentrations far above what's found in white pepper.
It is true that very high THC concentrations — far beyond Mr. Martin's levels — can cause mild hallucinations and paranoia, but even these effects are rare and usually seen only in very inexperienced users.
The nonlinear viscosity behavior occurs at very low particle concentrations far below 2 vol.%.
Furthermore, many contaminants accumulate in the sediments of rivers and reach concentrations far higher than those in the surrounding water.
When compared with the EU MRL as provided by the European Commission, all the detected pesticides had their concentrations far below their respective MRL for yam.
Total hydrocarbons, Cu, Ni, Cr and particulate organic carbon (POC) were all measured at concentrations far exceeding background levels in most sediment cores.
They can accumulate in soil at concentrations far higher than those that kill bees and persist there for up to 10 years.
But now researchers report that they can curb the spread of cancer cells in mice with drug concentrations far lower than the standard dose.
He states that hydrogen concentrations far in excess of the lattice concentration cannot be produced by elastic interactions alone: the amount of hydrogen in a so-called Cottrell atmosphere around a dislocation is small.
In our studies with TEP, we observed that despite accumulation of dissolved phosphate in the SGW at concentrations far in excess of what would be expected based on equilibrium considerations, detectable mineral precipitation did not occur [34].
