Two studies performed in The Netherlands in 2007 showed that more than 80% of the schools exceeded CO2 levels of 1200 parts per million (ppm) during classroom occupation [ 2, 3], which in The Netherlands is the advised maximum CO2 concentration for classrooms [ 4, 5].
Realigning a portfolio periodically is wise, all five experts said, because strong performance in one area could lead to an ill-advised concentration of assets.
One is that those diagnosed with melanoma should have serum 25(OH D concentrations tested and advised to keep serum 25(OH D concentrations above 75 100 nmol/l to reduce the risk of other cancers.
A hierarchical system has been developed to on-line advise on the concentration of inhaled volatile anaesthetics for controlling depth of anaesthesia.
Therefore, to produce an efficient activated carbon from the banana trunk that has a high adsorption capacity, it is advised to use a low concentration of phosphoric acid.
Although the use of oxygen at room air concentration is just advised for the beginning of the resuscitation process, it has been demonstrated that, for preterm and term birth asphyxia, the subsequent use of higher oxygen concentration may increase the formation of reactive species of oxygen.
Antibiotic susceptibility patterns were established with the VITEK2 system, E-test (bioMérieux) and the disk diffusion method (Oxoid AB, Malmö, Sweden), using the standardised bacteriological methods, minimum inhibitory concentrations and breakpoints advised by the European Committee on Antibiotic Susceptibility Testing [ 21].
MO participated in the design, interpretation of nevirapine plasma concentration results, read and advised in writing final manuscript.
Furthermore, there is no clear evidence that toothpastes containing less than the standard concentration of 1000 ppm are effective in preventing caries in young children and hence low concentrations are no longer advised for preschool children and infants [ 50].
Participants who consumed well water with As concentrations ≥50 μg/L were specifically advised to switch, if possible, to nearby safer well(s), defined as wells with As concentrations < 50 μg/L.
