This study presents the dynamic influences and changes of economic development on which the electricity price policy impact through theoretical model in China. The results show that from the static point of view, low electricity price level seems to be good for economic benefits. However, from a long-term and dynamic point of view, low electricity prices and economic development is not only having no obvious positive correlation, but instead a significant negative correlation.

Rainfall prediction is very crucial for India as its economy is based on mainly agriculture. The parameters that are required to predict the rainfall are very complex in nature and also contain lots of uncertainties. Although various approaches have been earlier suggested for prediction, the soft computing is found to be very effective in developing models which emulates human being and derives expertise like human being to adapt to the situations and learn from the experiences.

Changes of quality parameters upon heating were evaluated at different times of microwave heating on refined sesame and soybean oil high and compared to the results obtained for standard chemical indices (free fatty acids, peroxide, p-anisidine, nonenal content). Soybean oil was more extensively oxidised by microwave heating than the other oil probably as a consequence of absence of natural antioxidants.

Recycled fuels have been receiving great attention in order to supply energy recovery especially from waste products. An experimental study was conducted to evaluate the use of fuels produced from waste polyethylene (WPE) as an internal combustion engine fuel. Waste Polyethylene (WPE) was degraded thermally for conversion. The fuel collected at optimum conditions (414-480 °C range and 2 h reaction time) was fractionated at different temperatures and fuel property of the fractions was evaluated.

Microporous activated carbons with high surface area are of great interest for the remediation of textile wastewater in a sustainable manner. An activated carbon prepared from Euphorbia antiquorum L (EAC) was impregnated with Polyvinyl alcohol solution to provide mechanical stability and increase the abrasion resistance. The surface area of EAC and PVAC were 918 and 713.8 m2/g respectively. An adsorption characteristic of the Polyvinyl Alcohol Supported Activated Carbon (PVAC) was analyzed with the help of pseudo first order and second order kinetic models.

In this paper, the optimum composition of fly ash and plastic waste in a composite has been established based on various performance tests. The optimum dose of plastic waste in composite is 8% weight of fly ash. Laboratory tests indicated increased resistance to moisture damage in stone Matrix Asphalt (SMA) mixture containing composite as filler. The values of resilient modulus of the SMA mixture containing composite are fairly high compared to SMA mixture containing lime as filler.

This study presents various vegetable oils from edible and non-edible sources for preparation of biodiesel using KOH as catalyst and methanol as alcohol. Maximum biodiesel yield from all vegetable oils was obtained under following optimum conditions: reaction temp., 70°C; reaction time, 1 h; catalyst amount, 1% (by oil wt); and methanol to oil molar ratio, 6:1. Characteristics of biodiesel at optimum conditions were as per ASTM standards.

This review presents biological treatment methods for petroleum refinery wastewater, their applications, advantages and disadvantages. It covers refinery wastewater characteristics, different categories of biological treatment systems (suspended, attached and hybrid growths) and comparison between each system with conventional activated sludge process.

This study proposes a comprehensive noise abatement programme following the best practicable and economical option (BPEO) for implementation in metro city like Delhi for reducing annoyance and ill effects of traffic noise. It reviews potential applications of noise control barriers and vegetation for reducing road traffic noise and presents a design morphology and decision matrix using TOPSIS (Technique for order preference by similarity to ideal solution) approach for selection of appropriate sound barriers.

This study presents biogas production from fruit wastes at ambient temperature using anaerobic batch digester (500 ml). Co-digestion of fruit wastes were carried out with rice bran and cow dung. Biogas production from different samples was as follows: Sample A (fruit waste), 363; sample B (fruit waste, 75% + cow dung, 25%), 405; sample C (fruit waste, 75% + rice bran, 25%), 315; and sample D (fruit waste, 50% + rice bran, 25% + cow dung, 25%), 381 ml. From chromatographic studies, sample B has maximum methane content (80%) and sample C has maximum carbon-di-oxide content (50%).
