    Abstract: Physical properties such as compressive strength and tensile strength of concrete can be changed by adding a mixture of rice husk ash and palm oil boiler ash in concrete. The rate of absorption of water by the concrete mixed with rice husk ash and mixed with palm oil boiler ash was further tested. Levels addition of the mixture to be tested is 5%... Show More

    Abstract: In this study, 4-Methoxy-N-(3-phenylallylidene) aniline has been synthesized and characterized by FTIR and NMR spectroscopic techniques. The optimized geometrical structure, vibrational frequencies and NMR shifts of title molecule were obtained by using ab initio HF and density functional method (B3LYP) with 6-31G* basis set. The experimental and c... Show More
