Globally, the major source of environmental pollution as a result of mineral exploitation and processing is acid mine drainage (AMD).AMD refers to outflowing streams of acidic constituents from pyrite-bearing ore mines.The exposure of pyrite (FeS2) in coal waste Youth Jeans dumps to atmospheric oxygen and water in the presence of microbial communit
Reduction of lateral forces between the railway vehicle and the track in small-radius curves by means of active elements
Tanks This paper deals with a possibility of reduction of guiding forces magnitude in small-radius curves by means of active elements.These guiding forces characterize the lateral force interaction between the rail vehicle and the track and influence the wear of wheels and rails in curves.Their magnitudes are assessed in the framework of vehicle au
