Estimation of effective water vapour diffusion and mass transfer during quinoa (Chenopodium quinoa Willd.) drying

Agronomía Colombiana, 2023
This study shows the modeling of the convective drying operation of quinoa (Chenopodium quinoa Willd. var. Hualhuas) grains implemented in the General Algebraic Modeling System (GAMS) software. The proposed model was based on Fick’s second law.

A confinable home-and-rescue gene drive for population modification

eLife, 2021
Homing-based gene drives, engineered using CRISPR/Cas9, have been proposed to spread desirable genes throughout populations. However, invasion of such drives can be hindered by the accumulation of resistant alleles.
