dynamic economic load dispatch is one of the most important roles of power generation’s operation and control. it determines the optimal controls of production of generator units with predicted load demand over a certain period of time. economic dispatch at minimum production cost is one of the most important subjects in the power network’s operation, which is a complicated nonlinear constraine...

Relating the observed CO emission from giant molecular clouds (GMCs) to the underlying H2 column density is a long-standing problem in astrophysics. While the Galactic CO–H2 conversion factor (XCO) appears to be reasonably constant, observations indicate that XCO may be depressed in high surface density starburst environments. Using a multiscale approach, we investigate the dependence of XCO on...

Presently, the use of fossil fuels is not ecologically sustainable, which results in need for new alternative energies such as biodiesel. This work presents a review classification lipidic feedstocks and catalysts biodiesel production. It also pros cons different processes through obtained. In this context, cooking oil (WCO) has emerged an with high potential making process sustainable. A detec...

This study isolated a novel halotolerant Pseudomonas aeruginosa M4, that was able to degrade oil and produce rhamnolipids. Various carbon sources, nitrogen inoculum ratio, pH, temperature were tested optimize the degradation conditions. The highest rate of 85.20% lipase activity 23.86 U/mL obtained under optimal conditions (5% at 35 °C pH 8). components products different times analyzed explore...

In order to improve the degree of security and facilitation business environment; customs administrations are constantly working strengthen their own institutional innovation governance in control. As such, this paper establishes an evaluation index international supervision competitiveness based on eight indexes extracted from World Customs Organisation (WCO) Revised Kyoto Convention selects 2...

With the rising consumption of energy comes challenge depletion fossil fuels. Fossil fuels are non-renewable and finite sources with increasing demand as a result rise in human population industrialization. This concern has led researchers to seek alternative that both economically, technically viable, environmentally beneficial. Biodiesel is considered an source supply. It non-toxic, biodegrad...

Waste cooking oil or waste (WCO) is the remaining (or by-products) produced during food frying. In 2019, consumption in Bali Province was 4,735,057 L/month and WCO estimated about 3,314,540 L/month. The Government of plans to manage an integrated manner by processing it as derivative products with economic value. study aimed transform into high-value added (i.e. aromatherapy candles, liquid soa...

Biodiesel is regarded as a low-carbon substitute for petroleum-based fuels. This research study aimed to investigate 10 L batch-scale biodiesel production system from waste cooking oil (WCO) powered energy by solar and conventional electricity. The unit’s design considers the mass balance of system’s constituent parts. methoxide mixing chamber volume was calculated 2.5 with an electric agitator...
