Abstract This paper assesses the effect of galena emitted with dust from an electrostatic precipitator at Miasteczko Śląskie Zinc Smelting Plant (Poland) onto a soil and water environment. The Eh–pH diagrams plotted in temperature range − 3 to 25 °C serve determine conditions PbS stability under which its decomposition may occur, resulting release ionic forms lead into Determination mobility me...

in recent years, need to increase the convenience of trips in railway vehicles causes that train operators and manufacturers focus on reducing the noise level which is sensed by passengers. in this paper, first the state of modeling acoustic noise in cab train is discussed and natural frequencies and acoustic mode shapes are derived and then formulation of acoustic pressure in the cab will be o...
