The probability of attending school four our group of interest in this region increased by 6.5 percentage points after the expansion of the Bolsa Família program in 2007 and

In order to determine the effective diffusion coefficient (D ef ) of AITC through maize grains, the term referring to the sorption rate was added to the diffusion

Due to the scarcity of data reported in the literature on the drying of pellets for animal feeding, the values of the diffusion coefficient (D we ) from the present study

With the second domain, Le Claire’s and Hart’s models allowed both the bulk diffusion coefficient and the grain-boundary diffusion parameter ( α Dgb δ ) to be obtained. Iron bulk

Purpose: To retrospectively measure the mean apparent diffusion coefficient (ADC) with diffusion-weighted magnetic resonance (MR) imaging and the mean metabolic ratio (MET)

We proceed to calculate the diffusion coefficient from experimental data; this coefficient is used in the mathematical model to estimate the kinetics of boronizing

For the monthly mean values of “y” and “Q”, the value of “n” was calculated using the software Canal, so that 12 “n” values were calculated for each cross section of

By comparing the diffusion coefficient values for Fc oxidation from the oil phase and for water from droplets in the ME, it is observed that D Fc is, respectively, 60 and 40
