· Abstract. Several stressors like different types of heavy metals are found in the soil and can affect the growth and genomic integrity of wheat grains ( Triticum aestivum L.). The aim of this study was to compare the effect of exogenous Cd (30, 60, 120 mg kg −1 ), Ni (50, 100 and 150 mg kg −1) or Pb (100, 200 and 300 mg kg −1) on wheat

· Self-discharge is the one of the most significant disadvantages of nickel–cadmium batteries. At a nominal storage temperature of 20 °C, the rate of self-discharge, or the capacity loss is 10% in the first 24 h and around 20% per month for the first month. The rate decreases for storage beyond 1 month, but it is still significant for most
