It was found that when the center electrode was made the cathode, a clay that was originally dispersive stopped being so, and stayed that way even after the potential was switched off. This finding may be of significant value in seeking ways to prevent...

Due to electro-osmosis, a thin film of water appeared between the clay and the indenter when it was made the negative...

... ABSTRACT ABSTRACT: Line electrical resistivity method using physically infinite distance between current line electrodes is proposed to determine the location of mine workings. In this method at least three line electrodes are used. One of the current electrodes is used as a sinkhole electrode...
