KATAPAK-S is a type of structured catalytic packing, which is used in reactive distillation processes. The dry pressure drop characteristic (the pressure drop in the absence of liquid flow) is of significant importance for the investigation of process hydrodynamics. In this paper, the dry pressure drop within the catalyst packed channels of KATAPAK-S has been investigated using Computational Fl...

objective: oral iron drops are recommended for children aged 6-24 months to prevent iron-deficiency anemia. however, their use is associated with the potential risk of erosion and microhardness reduction of primary teeth enamel due to their high acidity. it seems that the combination of silicone oil, nano-hydroxyapatite and chitosan powder may be able to improve the microhardness and surface st...
