The present study was aimed at harvesting microalga, Chlorella vulgaris, by bioflocculation using seed powder of clearing nut, Strychnos potatorum. The research was essentially the prime step to yield a large biomass for utilising the cells in biodiesel production. Optimization of the parameters influencing bioflocculation was carried out statistically using RSM. The optimized conditions were 1...

This paper presents the preliminary optimum planning and design of PV-Wind hybrid energy system for a rural area of India. Optimization of any hybrid system is the process of selecting the suitable components and its sizing with proper operation strategy to provide ecofriendly, efficient, reliable and cost effective alternative energy to the society. Hence for design of hybrid system solar radi...

Modern agriculture is currently enduring rapid changes in defiance of the continuing increase global population and various consequent environmental challenges. Crop quality becoming as important crop yield can be characterized by several parameters. Extensive use chemical fertilizers leads to food safety concerns globally; hence, mycorrhizal symbionts have proven beneficial for sustainable gro...

Ultrasound-assisted extraction and direct analysis were compared with total digestion for magnesium determination in beer samples by flame atomic absorption spectrometry. The method used concentrated nitric acid under plate heating. In optimized instrumental conditions, validation of the analytical was promoted, good linear range (0.06 to 0.5 mg L�1), low limits detection quantification (0.04 0...

The global water shortage alert has been upgraded to a higher risk level. Consequently, sustainable approach for ecofriendly, energy efficient desalination is required agricultural and municipal reuse. In this study, an energy-efficient biological process was used treat chloride anions, which are the most abundant anion salt in seawater. Three algal species were studied: Scenedismus arcuatusa (...
