By contrast, in the office scenario, the best result is achieved by a Directive model with a high value of αr, i.e., a narrow beam diffusion.
By employing the recently developed fast axisymmetric DKI, we use stimulated echo acquisition mode to collect data over a two orders of magnitude diffusion time range with very narrow diffusion gradient pulses, enabling finely resolved measurements of diffusion time dependence of both net diffusion and kurtosis metrics, as well as model intra- and extra-axonal diffusivities, and axonal dispersion.
In addition, the narrow diffusion length along the radius of the microchannels created homogeneous reaction conditions for the uniform growth of CdS NCs, even at rapid growth rate that was induced by high OA concentrations.
Novel AmpliStain™ detection systems (SDT GmbH, Baesweiler, Germany) seem to overcome these constraints offering a more compact and deformable conjugate design that facilitates agile penetration through the narrowest diffusion pathways in tissue sections.
We used this dimensionless parameter because there is no reason to retain D and wg as independently adjustable parameters: rapid diffusion across a wide gap is equivalent to slow diffusion across a narrow gap and vice versa.
The small diameter of the channels (∼100 μm) leads to a short radial diffusion time, a narrow residence time distribution (RTD), and a low pressure drop.
Experiments in a cold model have been conducted to determine lateral solid diffusion coefficients in a narrow fluidised bed.
In the high temperature case a narrow lean premixed flame accompanies this diffusion flame on the airside.
Many spines are connected to the dendrite via a narrow neck that acts as a diffusion barrier to compartmentalize signalling in spines (Svoboda et al., 1996; Holbro et al., 2009; Bloodgood and Sabatini, 2005).
The secondary pore is a narrow channel, and the estimated rate of diffusion of NTPs reaching the A site (insertion site) through the pore is very slow.
