Extraction of Nicotine from Tobacco Leaves used for Animal Cleansing
Abstract: Nicotine is addictive. An average cigarette yields about 2 mg of absorbed nicotine, and in lesser doses of that order, the substance acts as a stimulant in mammals, while high amounts (50-100 mg) can be harmful. This stimulant effect is a contributing factor to the addictive properties of tobacco smoking. Nicotine’s addictive nature includes psychoactive effects, drug-reinforced behavior, compulsive use, and relapse after abstinence, physical dependence and tolerance. Nicotine can …

Optimal Tuning of PID Controller for a Continuous Stirred Tank Reactor (CSTR) Using Ant Colony Optimization
Abstract: Ant colony optimization (ACO)-based proportional integral derivative (PID) controller has been proposed for tuning optimized PID parameters in a continuous-stirred tank reactor (CSTR) process. In our proposed work, we have found that the tuning should have minimum value for rise time, peak time, settling time, etc. to be effective to design a CSTR system by optimal PID tuning. The simulation results of the proposed work reveal that the ACO-based PID …
