The selected critical quality attributes (CQAs) were the separation criterions between the critical peak pairs because the mixture complexity imposed a gradient elution mode.
The five harvest treatments (no-harvest control, single-tree selection, group selection, thinning, and clearcut) imposed a gradient of overstory canopy cover with reductions ranging from 12.8% in the controls to 83.6% in clearcuts.
In the model just described, it is assumed that the auxin acts to impose a gradient on the parameter k2.
For example, to test the hypothesis that the auxin acts to modify the rate of creation of inactive ROP, one would impose a gradient on the parameter b to give the form bw(x).
As an alternative to the methods based on FCS, one could impose a gradient of fluorescence and study the properties of this gradient.
To simulate the spiral waves we have, thus, created a phase defect by initially imposing a spatial gradient of the inhibitor along the x-direction and a second spatial gradient of the activator along the y-direction as α (t = 0, x, y ) = α s (1 + κ (2 x N − 1 ) ) γ (t = 0, x, y ) = γ s (1 + κ (2 y N − 1 ) ).
Both methods are based on imposing a temperature gradient on a suspended particle.
In summary, we propose a new approach to manipulate nanoparticles by imposing a thermal gradient on the system.
Filtered scalar diffusion is investigated by imposing a lateral mean gradient in the scalar for each phase.
A typical measurement consists in imposing a vertical temperature gradient through the PCM sample driven by a heat source, monitoring during the experiment time all the boundary conditions (temperatures and heat fluxes) and measuring temperature evolution in three locations within the PCM sample.
