Abstract:Gaussian integers is a set of complex integers a + bi where both a and b are integers. Long division still the effective method to test the divisibility of a Gaussian integer by another Gaussian integer. In this paper, instead of using long division, we used the real and imaginary parts to test if a Gaussian integer is divisible by another Gaussian integer. General formulas are also developed in this study from which these tests may be derived. Keywords:divisibility test, Gaussian integers.

Abstract: Inhibitive and adsorption properties of Janumet for inhibition of corrosion of mild steel in HCl was studied using weight loss and hydrogen evolution methods at 303 and 333 K. It was found that the studied drug inhibited the corrosion of mild steel in this acid induced condition The inhibition efficiency increases with increase in inhibitors concentration and decreases at a higher temperature. The adsorption of inhibitor on the mild steel follows Langmuir isotherm at two temperatures studied. Results obtained by these two techniques are in good agreement. Mechanism of physical adsorption is proposed from the apparent activation energy (Ea) and thermodynamic parameters obtained. The adsorption of the Janumet on the mild steel surface was also found to be spontaneous.
