Sentence examples similar to diffusion against the gradient from inspiring English sources

It was also observed that voids can be filled up by the penetrant, representing diffusion against the concentration gradient and thus indicating that concentration driven mechanisms are not applicable to the systems studied in this work.

The external force is computed as gradient vector flow (GVF), i.e. the diffusion of the gradient vectors.

The diffusive function should be monotonically decreasing so that diffusion decreases as the gradient increases.

This activity can lead to the diffusion of atoms with or against the gradient concentration of the metal.

Because of the high perfusion fraction in the liver, the apparent diffusion coefficients strongly depend on the gradient factors used in diffusion-weighted MRI.

Because of the high perfusion fraction in liver, the apparent diffusion coefficients strongly depend on the gradient factors used in diffusion-weighted MRI.

If the movement is with the concentration gradient it is called facilitated diffusion; if it is against the concentration gradient, this requires energy, and is known as active transport.

The driving force to move alcohol across a membrane by diffusion is the concentration gradient.

Because the gradient was established by taking advantage of 3D diffusion of biological molecules (e.g. netrin-1, sema3A, and NGF) in the HT-ChemoChip, it is expected that the gradient profiles are affected by the diffusion coefficients of different molecules, which is related to their molecular sizes (weights).

(j) Zoom-in on the gradient generator showing and dye diffusion.

The linearity of the gradient was checked by performing diffusion measurements on water over different ranges of the gradient.
