Impact of mine tailings on surrounding soils: Case study of Draa Lasfar mine, Marrakech- Morocco
The present study represents a first insight into the Draa Lasfar min (Marrakech - Morocco) to assess the degree of polymetallic pollution caused by anthropogenic activities (like mine extraction) and consequently the possible diffusion of heavy metals and to predict the risk of their mobility in the surroundings of the mine area. The edaphologic parameters pH and electrical conductivity (EC) w...
متن کاملAffect of zinc inhalation on body organisms in a mine
Introduction: Complications of zinc poisoning are analyzed in several studies. Among these, pulmonary fibrosis are reported. There is some doubts about chronic complications of zinc inhalation. Precise screening programs in zinc mine workers need previous knowledge of relative frequency of chronic complications due to zinc inhalation. So this study is held to recognize the complications and to ...
متن کاملMine, mine, mine: information theory, infostation networks, and resource sharing
The Infostations wireless data network architecture features discontinuous coverage and ultra-high radio rates for burst transfers of information between base and mobile. It has been shown previously that the infostations architecture can greatly increase the capacity of wireless data systems at the expense of increased delivery delay. In this work we explicitly consider the multiple access iss...
