The changes in I-V phase shifts increase power deposition efficiency in the plasma, which leads to a greater production of the ions and radicals required for material removal. The optimal discharge condition is a

Hydrogeochemistry of Mine Water, the problem associated with disulphide oxidation: “if mine workings could have been isolated hydrologically, operators, who must pump as much as 23 t of water per ton of coal from the anthracite mines of Pennsylvania, could have saved a great amount of money”. That was in 1964 and even today, after
