Abstract: The effect of gamma radiation on the mechanical and chemical properties of x CuO, (70-x) Bi₂O3_{, 20SiO₂,10 Na₂O, where 0 ≤ x ≤ 30 weight % were carefully studied in order to obtain information about the changes that appear in the structure of the glass matrix with the doping of copper ions. The glass matrix was fabricated by melt-quenching technique}... Show More

Abstract: This paper presents the environmental effects of gas flaring on pH values of the soil and rain water in some areas in Niger Delta. Different soil samples and rain water at various proximities from the gas flaring locations were taken. The samples collected were evaluated to determine the pH values of rain-water and that of the soil in the area unde... Show More
