Maximum Inhibition

Effect of Terminalia catappa leaves (TCL) extract in inhibiting corrosion of mild steel was investigated. In order to obtain the maximum inhibition efficiency, optimization of the process variables affecting corrosion of mild steel was carried out using the Box – Behnken Design plan and desirability function of Response Surface Methodology (RSM). The three parameters - varied include; TCL concentration (inhibitor), immersion time, and temperature and there effects in corrosion inhibition were established. The optimum conditions predicted from the quadratic model were inhibitor’s concentratrion (0.39 g/l), exposure time (8.68 hours), and temperature (36.06 oC) with the inhibition efficiency of 91.95 %. The data fitted well to the quadratic model which was validated. Adsorption of the extract’s component on the mild steel was responsible for the inhibitory effect of the TCL extract.The results showed that 97.92% of the total variation in the inhibition efficiency of TCL can be connected to the variables studied.

Cherry Tomatoes

Detachment of fruit from the plants with separation force is important in robotic harvesting. Compared with twisting pattern and bending pattern, the pulling pattern for cherry tomato harvesting is more simple, more flexible, and easier to implement in robotic harvesting. It was found that the detachment force is closely related to the location of the fruit separation. However, in the pulling pattern, analysis of the effect of harvesting parameters of cherry tomatoes at the calyx/fruit joint has still not been carried out in depth. In this paper, the goal of this research was to investigate the effect of different harvesting parameters on the minimal detachment force of cherry tomatoes at the calyx/fruit joint. Experiments were designed according to response surface methodology Box–Behnken design by maintaining three levels of three process parameters—grasping angle, horizontal angle, and pitching angle. Results showed that the pitching angle is the most important parameter, and the grasping angle has little effect on the detachment force, and the detachment force was found within the range of 0.58 N to 2.46 N. Results also revealed that the minimum separation force of the cherry tomato harvesting at the calyx/fruit joint was obtained by the optimum conditions of the grasping angle of 68°, the horizontal angle of 135° and the pitching angle of 0°. Moreover, desirability function has also been used to optimize the angle parameters. The confirmation experiments validate the reliability and capability of the developed model.

Aims: The aim of the present study was to develop and optimize a Stealth Liposomal Drug Delivery System of microtubule inhibitor using Box–Behnken Design and Desirability function. Study Design: Development and Optimization of Stealth Liposomes. Place and Duration of Study: The study was carried out in the Department of Pharmacy, Annamalai University, between September 2020 and May 2021. Methodology: Stealth Liposomes were prepared by the thin-film hydration method (TFH). The formulation was optimized using Box – Behnken design to study the effect of independent variables, Amount of Egg Phosphatidylcholine (X1), Amount of Cholesterol (X2), and Amount of DSPE-PEG 2000(X3) on dependent variables Entrapment Efficiency (Y1) and In-vitro drug release (Y2). Results: Entrapment efficiency of the Stealth Liposomes ranges from 56.35 to 84.25%and in-vitro release ranges from 62.38 to 94.26%. The optimized formulation was found using the desirability function to get maximum entrapment with maximum drug release. The optimized formulation showed entrapment efficiency of 80.46% and in-vitro release of 90.11%. Conclusion: Stealth Liposomal Drug Delivery System for microtubule inhibitor was successfully developed and optimized using desirability function in Design Expert software by a three-factor, three level Box – Behnken design.
