Low reactive gas concentrations, high temperatures and low methane/oxygen ratios enhance microstructure formation.
In early August 2008 when ozone reached concentrations high enough to cause injury, plants generally were wilting under the hot and dry conditions then, consequently stomates were closed limiting ozone influx into leaves and thus very little damage was observed.
For those who had stopped eating it, the reasons given were a combination of the ethical implications as well as recent evidence showing that a percentage of shark fins assessed from five Chinese cities (including Hong Kong), contained mercury and methylmercury in concentrations high enough to be considered unsafe for human consumption.
While this model may be expected to be valid for moderate agent concentrations, high local concentrations of one or both of the contrast agents could result in deviations from the linear model as the agents compete for interactions with the surrounding water molecules.
Otherwise, the stress concentrations that build up around abrupt changes of shape can become too great to manage.Similarly, the rough edges of punch-riveted holes can cause stress concentrations high enough to initiate fatigue cracks.
Radioactive iodine has a half-life of just eight days, and it was not thought to be present outside the power plant in concentrations high enough to cause immediate health problems.
The vapor/liquid equilibrium diagram for the water/formic acid system is shown, where in analogy to the case of acetic acid the range of low formic acid concentrations (high water concentrations) is represented by a straight line.
The goal of this study is to explain how RNA can remain soluble and available for interaction with other molecules in the cell despite the presence of spermine at concentrations high enough to precipitate DNA.
Additionally, systemic administration may not lead to local drug concentrations high enough to yield disease modification because of rapid systemic metabolism or lack of sufficient partitioning into the diseased tissue compartment.
But there are only a few places on earth with concentrations high enough to mine.
CO2 concentrations high is worse than lack of oxygen because we don't need as much oxygen as is in the room.
