Sentence examples for concentrations of background from inspiring English sources

In a prospective Danish cohort study, plasma concentrations of background PFOA exposures were not associated with prostate, bladder, pancreatic, or liver cancer (Eriksen et al. 2009).

We then performed 3D analysis to determine whether the small concentration of the control molecules could be accurately quantified in the presence of increasing concentrations of background DNA (Fig. 2).

The reaction mixtures were then partitioned, cycled, and the droplets analyzed to determine whether the small concentration of the control molecules could be accurately assessed even in the presence of high concentrations of background, HCT 116 DNA.

Our data show that impaired semen quality in adulthood results from exposure in utero, as well as continuous exposure through breast-feeding during "neonatal minipuberty," with adverse effects starting with a dioxin exposure range of 19 40 ppt and higher (the concentrations of background dioxin-like chemicals must also be added).

Therefore, the risk of influence from the changing concentration of background gas is higher.

Growth of electron concentration (at the stable concentration of background charged impurities in the well) leads to strong increase of mobility and appropriate reduction of resistance due to two simultaneous processes: decrease of hole concentration and growth of screening [1].

The presence of aggregates was monitored by electrophoretic measurements, in which the change of isoelectric point in lactoferrin solutions was observed and found to depend on the concentration of background electrolyte.

The TCO operation, together with pattern recognition, may also reduce the baseline and response variation due to changing concentration of background gases (4 10% O2 and 0 70% RH), and thus it may improve the overall sensor performance.

In order to improve resolution, an orthogonal experimental design was employed, altering the concentration of background electrolyte, organic modifier, pH, capillary temperature and applied voltage in a multivariate manner.

Further, Mn-MoS4 can completely tolerate the impact of huge concentration of background electrolytes (Ca2+, Mg2+, Na+, Cl−, NO3− & SO42−), and effectively control the concentrations of Hg2+, Ag+ and Pb2+ ions from tap water, lake water or industrial wastewater far below the limitation in drinking water.

The concentration of background sugars contained within the enzymatic preparation was assessed and taken into account in the calculations.
