Equilibrium and kinetic studies on reactive extraction of lactic acid
Abstract: Abstract: Lactic acid has became a growing requirement in various fields so reactive extraction has been employed to recover by using tri pentyl amine and tertiary butyl amine in different diluents (1-octanol, chloroform and dimethylene chloride). Physical and chemical equilibrium isotherms, KD, loading ratio (Z) were measured through equilibrium studies for (1:1) and (2:1) acid amine complex formation at room temperature. By conducting kinetic studies in batch type reactive system …

Effects of Reinforcing Elements in Soil Reinforcement
Abstract: The inclusion of reinforcing elements in a soil mass improves its geotechnical properties. The principle behind soil reinforcement is that the reinforcing elements absorb the tensile load and shear stress within the reinforced structures and hence prevent the shear failure and settlement. The friction developed between the interface of soil and reinforcing element improves the properties of soil. Different types of natural and synthetic fibers have been used in various …

Assessing the Impact of Soil-Structure Interaction on Seismic Performance of Step Back and Set Back Buildings on Sloping Ground
Abstract: When constructing framed structures on sloping ground, either step back or step back and set back configurations are typically adopted. Due to the varying heights of columns towards the slope and the unsymmetrical nature of these buildings, they are subject to large forces such as shear forces, bending moments, torsional moments, and unequal distribution. In the past, it was common practice to assume that structures were fixed at the base, …
