A multivariate study on the effect of 3D printing parameters on the printability of gluten-free composite dough.

Background: The advancement of three-dimensional (3D) food printing technology is significantly influencing the food processing industry. The present study utilized extrusion 3D printing to create a gluten-free dough composed of little millet flour (LMF), amaranth seed flour (ASF) and curry leaf flour (CLF). The primary objective was to elucidate the effects of various extrusion-based 3D printing conditions, including extruder nozzle diameter (ND), extrusion rate (ER), print speed (PS) and layer height (LH) on the printability parameters of the dough.

Effectiveness of an educational program to promote pesticide safety among pesticide handlers of South India.

Objectives: Occupational poisoning with pesticides is common in developing countries because farmers are often under trained, illiterate and consider it impractical and expensive to use safety equipment, especially in tropical climates. Greater benefit of education programs on prevention can be obtained if initiated in areas having higher occurrence of poisoning. Hence, the present study evaluated occurrence of poisoning and effectiveness of educational interventions among pesticide handlers in areas having high occurrence of occupational poisoning.
