This limitation was not observed in samples with higher concentrations such as waste samples or urine.
Hence, GDH is less efficient in low ammonia concentrations, such as in M9-YE medium.
For the isotopes with large concentrations, such as 238U and 239Pu, the mass differences were 0.38% and 0.01% respectively.
Certain sediment properties can affect PAH distribution and concentrations, such as TOC and/or clay content [24].
Traditional methods to reduce rock dust concentrations, such as a water spray, ventilation, and foam are not effective.
Theoretically, these kinetic parameters should be independent of the reactant concentrations such as resin weight and initial heavy metal concentrations.
Other elements were also found in lower concentrations such as Mg, S and Si, as seen in Table 3.
The presence of dust in the air stream reduced the cyclone pressure drop by as much as 30%, even at extremely low concentrations, such as 0.2 g/m3.
Micro-deformations at localized stress concentrations, such as inclusions, can further augment the local internal stresses needed for the incipient crack to nucleate and propagate.
In the absence of severe wear, gross fracture of total joint replacement components tends to originate from stress concentrations such as fillets, undercuts, and grooves.
More particularly, seasonal samples should be kept separately for chemicals with expected seasonal variation in concentrations, such as some metals or mycotoxins.
