Capillary rise is a phenomenon that must be considered an inevitable factor when dealing with unsaturated gypseous soil. This study investigates the behavior of soil under capillary action, where different gypsum content and densities are experimentally tested in developed laboratory model consisting Transparent pipes 1 m long 0.05 diameter. All placed inside rectangular basin dimension (1500×5...

The capillary pressure J-function is a dimensionless measure of the capillary pressure of a fluid in a porous medium. The function was derived based on a capillary bundle model. However, the dependence of the J-function on the saturation Sw is not well understood. A prediction model for it is presented based on capillary pressure model, and the J-function prediction model is a power function in...

A category of new photochromatic storage material has been found suitable for rewritable digital video disc (DVD). The ratio of transmissivity before and after the write-in process is 3:1 at X = 450 n m (blue) and 1:7 at X = 650 nm (Ed), with a transition time of 2-3 ns. The number of write-erase cycles is about 1,000. MO aor PC can have the same advantage. However, since there are some specid ...
