Sentence examples for tracer composition from inspiring English sources

The different profile of emptying and filling of the lung units causes discrepancy in their gas tracer composition, thus creating regional differences within lung units for tracer inert insoluble gases such as helium or methane [ 9, 10].

These results, paired with the information from more traditional approaches (e.g., tracer testing and composition of the clog matter) are being incorporated into the latest treatment wetland models.

One factor is that the SUV is a semiquantitative measurement that can be affected by several biological factors (e.g. body size, weight composition, tracer metabolism and blood flow), or technological factors related with the acquisition and reconstruction of the image (e.g. field of view and matrix size) [ 35].

The effective surface topography is tracked using the composition tracers (i.e. searching the interface between air and rock), which allows for subgrid resolution.

StagYY uses a multigrid solver to obtain a velocity pressure solution at each timestep on a staggered grid, a finite-volume scheme for advection of temperature and tracers to track composition.

These tracers hold the composition of the modeled lithologies and allow tracking the equilibrium mineral assemblages and changes in water content along the slab and in the mantle wedge.

The response of conventional monitoring data (including water table mounding, soil gas pressure, soil gas composition and tracer gas response) was compared with the results of cross-borehole electrical resistance tomography (ERT), which provides a sensitive indication of the pattern of air flow in the saturated zone.

The composition of the tracer solution is the same as for the background electrolyte solution described above, with the inert tracer being added.

The effect of the temperature and alloy composition on the tracer and vacancy correlation factors and the short range order are also investigated.

Combined with the known composition of the tracer spike, these two ratios define the K Ar age using a single sample aliquot and without the need for extreme temperature or a mass determination.

Tracer bullets have a column of pyrotechnic composition in the base that is ignited by the flame of the propellant; this provides a visible pyrotechnic display during the bullet's flight.
