Maize Yield and Economic Response to Integrated Organic and Nitrogen Fertilization in Gaza Province, Mozambique

Plant-Environment Interactions, Volume 7, Issue 4, August 2026.
ABSTRACT Low maize yields in Mozambique remain a major constraint to food security, primarily due to soil nutrient depletion and limited access to affordable fertilizers among smallholder farmers. Integrated nutrient management, combining organic and mineral inputs, offers a promising approach to improve both productivity and soil health.

Influence of an Electromagnetic Field on Direct Reduction of Iron Oxide Using Hydrogen as a Reducing Agent

steel research international, Volume 97, Issue 8, Page 4119-4125, August 2026.
This study investigates the reduction of pure iron oxides and industrial iron ore using hydrogen gas as a reducing agent. Additionally, to determine whether the reduction process can be accelerated, electromagnetic fields of 50 Hz and 25 kHz were applied.
