    Abstract: The study of the corrosion inhibition of mild steel in sulphuric acid (H2SO4) by the leaf pastes of Sida Acuta was probed using the weight-loss technique. The highest inhibition efficiency of 91.46% with a reduction in corrosion rate from 3.1338mg.cm-2.h-1 to 0.2825mg.cm-2.h-1 was achieved by the addition of the leaf pastes of Sida Acuta at 30g per...

    Abstract: This paper investigate the rate of dissolved calcium deposition in fine and coarse formation, the study is to monitor the rate of dissolved calcium content at different lithostratgraphy in the study location. Homogeneous fine and coarse formation were observed to deposit in the study location, organic soil were insignificant since the formation dep... Show More

    Abstract: A ten-storied building with shear walls in two directions with respect to the direction of lateral load acting on the building has been studied here. The finite element based software, ETABS (version 9.6) has been used for determining the moment at different area objects due to the lateral load and Simpson’s one-third rule has been used to calculat...
