Our controls received, and largely reported seeking, no additional help, giving us confidence that inadvertent active intervention (contamination) was not the reason for the observed changes.
Thus, the method can be used for online measurement of numbers of metabolically active cells indicating contamination in case of deviation from the normal profile.
Highest priority was paid to the purity of all materials used in the ribonuclease activity assays to exclude contamination by ribonuclease-active compounds at all experimental stages.
The results show that chloride contamination promotes active corrosion.
Analyses of 60 wells paint a picture of contamination near active gas wells.
We maximized enrollment by using a financial incentive and controlled blood culture contamination by active monitoring, regular feedback, and retraining health providers.
In contrast, Swedish and Finnish studies have indicated that heavy contamination of active sludge basins with legionellae is very common [ 7], (Unpublished data, Kusnetsov J, Torvinen E, Lehtola M and Miettinen IT).
Contamination may be due to active urine, or occasionally contaminated radiographer's fingers, for example on the image of the skull through holding the head.
The criteria for the selection of suitable systems were fast electrochemical kinetics and minimal cross-contamination of active electrolytes.
With a careful choice of all materials and components, and with good control of the water contamination in the active gas, the ATLAS TRT will operate reliably for 10 years at the LHC design luminosity.
