The behavior of electrons in general many-electronic systems throughout the density functionals of energy is reviewed. The basic physico-chemical concepts of density functional theory are employed to highlight the energy role in chemical structure while its extended influence in electronic localization function helps in chemical bonding understanding. In this context the energy functionals acco...

Abstract The aim of this work is to highlight the evolution physico-chemical properties peroxide crosslinked polyethylene (XLPE) insulation material exposed electrical aging. Specific analysis and characterization studies were carried out determine effect aging on different samples at micro macro levels. Based analytical investigations, it was shown that yielded significant changes in chemical ...

in this research, the physico-chemical water quality parameters and the effect of climate changes onwater quality is evaluated. during the observation period (5 months) physico-chemical parameterssuch as water temperature, turbidity, saturated oxygen, dissolved oxygen, ph, chlorophyll-a, salinity,conductivity, and concentration of total nitrogen (nutrient level) as main pollutant factor have be...

the river kabini which is tributary of cauvery drains through industrial area at nanjangud, karnataka. out of the sediment load carried by the river, 2micron the clay fraction was analyzed for total heavy metal contents and advanced statistical techniques such as cluster analysis and correlation matrix were applied in order to investigate the source of heavy metal concentration in the sediments...

the genus azolla forms a group of small-leafed, floating aquatic ferns native to the tropics, subtropics, and warm temperate regions of africa, asia, and america. for several decades, these ferns have been utilized for various purposes: e.g. as green manure, feed for animals, but also for the removal of different metals (e.g. hg, pb, cr and cd) through wastewater treatment or for elimination of...

guar gum and whey proteins concentrate (wpc-35) were used as functional additives to improve the functional characteristics (hardness and meltability) of the na-caseinate-based imitation cheese. also, the alterations in the composition, sensory acceptance, color, and texture caused by these ingredients were evaluated. imitation cheeses were formulated with three levels each of wpc (0, 1.5, and ...

among the environmental problems in nigeria is the lack of proper management of municipal solid wastes (msw), which is capable of releasing hazardous chemicals via leachate to the surrounding environment. in this study, the potential toxic effects of raw leachate obtained from aba-eku landfill (aerl) on clarias gariepinus; and the microorganisms that may be present in the leachate were investig...
