Current safety standards for O3 levels are exceeded frequently in most Mediterranean countries.
For the operator, the pressure fluctuations hamper titration of the desired set airway pressure while the pressure safety alarm limits may be exceeded frequently.
In Belgium, this standard is barely met at present, and although minor improvements due to emission reduction measures are expected, the limit value of 50 μg/m will continue to be exceeded frequently in the coming decade.
For many diseases, the remaining variation not accounted for by these methods means that (i) determining the endemic channel is highly uncertain and (ii) that the outbreak threshold line is exceeded frequently, briefly and sporadically (Badurdeen et al., 2013).
The threat of bleaching is particularly alarming because many corals already live near the upper limits of their thermal tolerances, and most climate-change models predict that these tolerances will be exceeded frequently in the coming decades, leading to widespread coral death and a resulting loss of the reef habitats (Hughes et al. 2003).
Although second generation sequencing has lowered the cost per sequenced base a hundred-fold and allows the resequencing of complete genomes in a fraction of the time, the size of the sequencing target still exceeds the frequently available budget.
H & R Block, the tax preparer, and its banking partner, Household Finance, are accused of illegally overcharging customers by providing "refund anticipation loans" at interest rates frequently exceeding 100percentt.
The largest flocks of terns were encountered at SeaGen North during peak flood tides (Fig. 2c), with aggregations frequently exceeding 50 birds (Fig. 2a).
Summers are hot, with daytime highs frequently exceeding 100 °F (38 °C), and winters are cold, as nighttime lows generally are well below freezing.
Particle (as particulate matter) and ozone pollution levels are of particular concern, with peak particulate matter levels frequently exceeding the current national air quality standard in most of Australia's metropolitan areas.
All sites exhibit similar patterns (see Fig. S1, in the Supplementary Data), with daily doses at the mid-latitude sites frequently exceeding 10 SED when the peak UVI remains less than 3.
