Removal of direct blue dye by electrocoagulation method has been investigated using aluminum
electrode in a bench-scale electrochemical system. Current density, NaCl concentration,
electrocoagulation time, and dye concentration has been studied as effecting parameters in color
removal efficiency. Increasing of current density will increase the color removal efficiency and
energy consumption as well. While increasing NaCl concentration increase the color removal

The corrosion behaviour of carbon steel in 1M HCl solution containing various
concentration of methyl urea range (10-35×10-2)M at temperature range (285-
313)K was investigated. The corrosion inhibitive action of methyl urea on carbon
steel was studied using weight loss measurement and atomic absorption analysis to
find the amounts of dissolved metal in acidic solution in presence and absence of
methyl urea. The results showed that urea caused protection efficiency reached to
82% when (10-3)M methyl urea concentration was used. The coverage () of metal
surface by methyl urea could be obtained from the rate of corrosion in the presence
and absence of methyl urea in the acid solution. Results
The total -n reaction cross section for radioactive fission products have been
evaluated in the region of energy near the giant dipole resonance, from the threshold
energy up to around 30 MeV. The selected fission products lay in the range of
medium mass number, namely: 87Rb, 90Sr, 93Zr, 106Ru, 123Sn, 127Te, 129I and 137Cs.
These radioactive isotopes were chosen as part of the radioactive waste from 235U
fission. Total cross section results were used to calculate the number of incinerated
nuclei, and this method shows efficiency in reducing the radioactivity of these
isotopes. The obtained results show that the incineration rate of radioactive nuclei
increases with the flux of the incident -r
