The Gm and In V allotypes of serum are inherited in Mendelian fashion and their existence imposes important constraints on current theories of immunoglobulin synthesis. The incidences of particular factors vary markedly with different population groups, a fact of anthropological interest. In medico-legal investigations allotypes can aid in cases of disputed parentage (both paternal and maternal...

The environmental impact of wind power plants over their life cycle is divided into three stages: construction period, operation period and retired period. The impact is mainly reflected in ecological destruction, noise pollution, water pollution and the effect on bird migration. In response to these environmental effects, suggesting reasonable locations, reducing plant footprint, optimizing co...

water quality trading is a new approach in pollution control which satisfies water quality standards suggesting minimum cost solutions. this method uses tradable discharge permits based on pollution transfer coefficient in a river. this paper tries to establish a water quality trading program in a river basin according to transfer coefficients between pollution sources and evaluate cost effecti...

Lessening the leakage of surface water can reduce the waste of water resources and ground water pollution. To solve the problem that Mengxi River could not store water enduringly, geology investigation, theoretical analysis, experiment research, and numerical simulation analysis were carried out. Firstly, the seepage mathematical model was established based on unsaturated seepage theory; second...

In 2004,ammonia concentration in raw water of Sitalakhya River at the eastern periphery of Dhaka was found higher than the expected rate of 4 mg/Lforecasted in feasibility studies,with a value of about 8 mg/L, which could not be removed by conventional treatment chain employed at Dhaka, hence, recentlyan ammonia removal plant has been constructed. This important background has ledto the current...
