Modeling of a turning tool holder with finite elements and simulation of its free vibration frequencies
Published 2012“…This latter difference is unavoidable, due to the experimental test setup whereby the tool holder is clamped within the fixture with only 2 pins as opposed to the more rigid boundary condition applied to the finite element model, whereby the whole holder length within the carriage is rigidly supported at the element nodes. …”

Effect of dual flocculant by unmodified manihot esculenta starch and aluminium sulphate on the removal of chemical oxygen demand optimized by response surface methodology
Published 2024“…Besides the performance of COD removal increased, the dosage of the chemical coagulant was reduced by up to 64% at the optimum condition of 18 mg/L alum dosage, 307 mg/L starch dosage, pH 9, and 27 mins settling time. The analysis of variance (ANOVA) indicated that the quadratic model was significantly developed with a p-value < 0.05. …”
