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) ...

nitrogen use efficiency and life cycle of root nodules in alfalfa after different mineral fertilization and soil cultivation practices were studied. field trial was conducted in the institute of forage crops, pleven, bulgaria on leached chernozem subsoil type and no irrigation. the next treatments were tested: i) for fertilization as follows: n0p0k0 (control); n60p100k80 (an accepted technology...

Abstract It is known that Intuitionistic fuzzy models give more precision, flexibility and compatibility to the system as compared classic models. tree has an important role in neural networks, computer clustering. In design of a network, it analyze connections between levels. addition, intuitionistic becoming increasingly significant applied different areas real life. The study proposes novel ...
