Abstract:
... Marble waste is generated in a fairly large quantity in the world and has been causing serious environmental problems. Usually, the marble waste is reutilized as cement replacement or aggregate replacement in concrete production. But these two methods of utilization have some drawbacks. In this study, an alternative method, called the paste replacement method, in which marble dust (MD) is added to ...

Abstract:
... Rice has a much enhanced arsenic (As) accumulation compared with other cereal crops. How As is transported in xylem exudates of rice growing in soil remains unknown. We quantified the chemical species of As in xylem exudates of rice growing in arsenic-contaminated soil (62.5 mg As per kg soil) under flooded and aerobic conditions. In the aerobic treatment, the predominant species of As in the xyle ...

Abstract:
... Debris flows are typically caused by natural terrain landslides triggered by intense rainfalls. If an incoming mountain torrent flows along sloping channels at high velocity, huge amounts of sediment (from landslide dams and eroded channel beds) will be entrained into the flows to form debris flows. It is likely that large debris flows are due to the failure of many landslide dams of different sca ...
