this study investigated different concepts for natural-gas-fired power plants with the co2capture, and compared them based on the net plant efficiency and emission of co2. the cycles were based ona six oxy-fuel, one post-combustion and two pre-combustion capture concept. this paper presented theresults of an environmental evaluation performed by the application of the life cycle analysis (lca) ...

The amount of waste in the world continues to increase framework population, purchasing power and technological developments since past years this necessitates need for sustainable integrated management waste. disposal without being used recycling recovery process causes serious resource losses, both materially energy. "zero waste" movement has recently gained importance as an alternative domin...

glucose-6-phosphate dehydrogenase (g6pd) deficiency is a common enzyme deficiency in the world. it's prevalence iniranis about 12% in male & about 1% in female. the present study did examine the relation between the development of preeclampsia and g6pd deficiency. it was investigated whether or not the risk of preeclampsia in g6pd deficient women is higher than that in normal pregnant women. a ...

Massive CO 2 removals will be necessary to avoid climate tipping. Comparing with past, current and future carbon stocks flows reveals the importance of avoiding fossil emissions completely developing scalable technical solutions.

the present paper is aimed at describing a “closed cycle” power plant schematic (soft, solar oxygen fuel turbine) with macroalgae (seaweed) cultivation in a pond, combustion of its organic matter in a fluidized bed boiler of rankine cycle and return of the combustion products to the pond to feed algae. the oxygen used for combustion is released to atmosphere in photosynthesis. as a renewable fu...
