    Re-emission of slow positrons from tungsten at elevated temperatures by Al-Qaradawi, I. Y.

    Published 2002
    “…Irrespective of target history, no sharpening of the energy spectrum of re-emitted positrons was observed as the remoderator temperature was increased. Further, a steady decrease in the apparent re-emitted positron intensity was observed, attributed primarily to the increase in positronium formation, as the temperature of the foil was increased from 20 to 500 °C. …”

    Effects of soaking, acidity and temperature on cadmium and lead removal from rice by Al-Naimi M.

    Published 2020
    “…Results showed that few samples have shown lead concentrations above the maximum limit set by the World Health Organization (WHO) and the UN Food and Agriculture Organization (FAO) of 0.2 mg/kg, whereas, all cadmium concentrations were below the limit of 0.4 mg/kg. A decrease in lead and cadmium concentrations were observed with increasing time of soaking. …”
