Studies on Extraction, Modelling and Purification of Quercetin from Peel of Allium cepa
Abstract: ABSTRACT Quercetin is an anti-oxidant, which very efficiently scavenges highly reactive biological species such as peroxynitrite and hydroxyl radical. Quercetin belongs to the flavonoid’s family. The present studies on optimization of physico-chemical parameters like effects of different solvents, different solvent percentages, particle size, pH and extraction time for the extraction of quercetin was studied. The highest quercetin concentration for optimized conditions was 38 µg/ml. In the soxhlet extraction process, the …

Desizing of Cotton Fabrics With Enzymes for Improved Performance
Abstract: Desizing of cotton substrates with Amylase enzymes has been practiced since long time and is commercially successful. Amylases convert the water insoluble starches, used during sizing operation for enhancing the performance of the warp yarns, into water soluble products which are removed during subsequent washing. The use of enzymes for desizing is quite safe for the cotton substrates and do not cause any detrimental effect on the cotton cellulose unlike …

A Review Paper on the Working of Petroleum Refineries
Abstract: ABSTRACT- What’s happen in petroleum refinery, why we have a tendency to install refineries and the way crude is refined, we will understand in simple means by this article. Crude can't be use directly, produce plenty of pollution and too much expensive also, therefore we'd like refined crude and establish several rock oil products like (kerosene/LPG/petrol/jet fuel/gas /naphtha etc.) for our desires for energy, heat and plenty of other’s needs. …

Effect of polymer architecture on the gas separation performance of PIM-1 membranes
Abstract: Molecular simulations are used to demonstrate the effects of chain architectureson the gas separation performance of PIM-1 membranes. Four different architectures(linear, H-shape, star, and dendritic) were considered to investigate the transport propertiesof four industrially relevant gases (CO2, CH4, O2, and N2). The results obtainedfor the linear PIM-1 agree well with the available experimental data. The simulationsindicate that it is indeed possible to tune the free volume morphology of PIM-1 membranesby …

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, …
