The ongoing load-shedding and energy crises due to mismanagement of energy produced by different ... more The ongoing load-shedding and energy crises due to mismanagement of energy produced by different sources in Pakistan and increasing dependency on those sources which produce energy using expensive fuels have contributed to rise in load shedding and price of energy per kilo watt hour. In this paper, we have presented the linear programming model of 95 energy production systems in Pakistan. An improved multiverse optimizer is implemented to generate a dataset of 100000 different solutions, which are suggesting to fulfill the overall demand of energy in the country ranging from 9587 MW to 27208 MW. We found that, if some of the power-generating systems are down due to some technical problems, still we can get our demand by following another solution from the dataset, which is partially utilizing the particular faulty power system. According to different case studies, taken in the present study, based on the reports about the electricity short falls been published in news from time to t...
The Chemical Composition and antimicrobial activity of peel essential oil of sweet orange Citrus ... more The Chemical Composition and antimicrobial activity of peel essential oil of sweet orange Citrus grown in Peshawar, Pakistan were investigated. The major chemical composition concentration of essential oil were D-Limonene was 95.62%, beta-myrcene was 2.78%, alpha-pinene was 0.75%, n-octyl acetate was 0.32%, beta pinene was 0.2% and beta farnesene was 0.09%. The antimicrobial activity of sweet orange peels oil were evaluated using well diffusion methods towards 4 bacteria and 3 fungal cultures. The results were compared with those synthetic antibiotics Gentamycin, Tetracyclin, Fluconazole and Nystatine. The Salmonella typhi were inhibited by essential oil with inhibition zone 13mm (50µL), 10mm (25µL) and 06mm (10µL). The Staphylococcus aureus ATCC6538 with the inhibition zone were 21(50µL), 18mm (25µL) and 07mm (10µL). No inhibition zone was observed for rest of bacteria E. coli and B. cereus. While all the tested fungal strains were showed a strong resistance to these oils.
