Sentence examples for diffusion of the tracer from inspiring English sources

The rate of diffusion of the tracer through the wall of the permeable chamber was rapid and the effective diffusion into the groundwater was controlled by the mass transfer limitations at the groundwater/chamber interface with gas entrainment proportional to the groundwater velocity past the chamber.

A hemispheric brain perfusion index (BPI) [16] was determined before the start of the initial back diffusion of the tracer from the brain to the blood as follows: mathsf{B}mathsf{P}mathsf{I}=mathsf{100}times mathsf{mathsf{ROI}frac{mathsf{10}times {mathsf{ROI}}_{mathsf{aorta}}mathsf{size}}{{mathsf{ROI}}_{mathsf{brain}}mathsf{size}}, (1).

There was little diffusion of the tracer into cortical areas surrounding the filter paper.

The incorporation experiment was performed at a temperature of 280 °C and the sample was quenched to room temperature after the incorporation procedure in order to minimize the diffusion of the tracer in YSZ [34,35].

The surgery was carried out as described above (induction of experimental prion disease), using a glass micropipette to inject biotinylated dextran amine, with an outer diameter of ∼15 20 μm, recommended to significantly reduce the damage to neurons and diffusion of the tracer at the injection sites.

The multi-lamination pattern was established; molecular diffusion of the paramagnetic tracer was observed and compared with an analytical model.

The diffusion of the conservative tracer (HTO) in experimental cells Prec2 and Prec3 indicated the onset of porosity reduction (i.e., change in flux curve slope, Fig. 2), and the significantly decreased flux indicated a change in the material's transport properties.

The extent of intramyocardial microbubble-enhanced imaging (maximal depth and width) was measured to identify local diffusion of the microbubble tracer at the injection site.

High levels of fluorescence from GB and RB injections were typically restricted to the injection sites because diffusion of these tracers is low.

The model revealed that the width of the parabolic tail reflected the magnitudes of diffusion and permeation of the tracer in the plant stem.

Diffusion of the calcium chloride tracer into the beads was measured and found to follow Fick's Law.
