The effect of pellet chemical composition and burning temperature on pellets’ properties of the Gol-e-Gohar hematite recovery plant was investigated in this study. Green pellets of different sodium hydroxide ratio and hydrated lime were prepared as well. Then the pellets were burnt in a muffle kiln under different temperature conditions. The Design Expert software was employed to explore ...

Walnut shells can be used as fuels in power plants directly or biochars obtained by pyrolysis torrefaction. They are an example of clean waste biomass which shows a low ash content and high Net Calorific Value, making them excellent for energy recovery industrial non-industrial applications, such bakeries, restaurants, homes. Their main inconvenience is their bulk density. Densification possibl...

XRF (X-ray fluorescence analysis) has been applied as the method for analysis of plant samples, but not in its full potential. This would be highly suitable monitoring programs and screening studies. A simple sample preparation procedure makes this technique time cost-effective, although absence adequate calibration standards some analyzed matrices can a significant limiting factor. Nevertheles...

In recent decades, the issue of stress and its negative consequences such as violence in the workplace, increased accidents at work, absenteeism and burnout, have deleterious effects on the efficiency and economy. The aim of this study was to determine the occupational stress of pelletizing industry workers and its determinants. This study was descriptive-analytical and cross sectional. Among w...
