Imbibition of polypropylene cloth was investigated using oil and kerosene in water emulsions with different concentrations of inner phase. Microscopic photographs revealed that no phase separation occurred during sorption. It was found also that the cloth used was hydrophobic but the velocity of sorption processes were dependent on the dispersed phase concentration and on liquid used as internal phase.

The great number of object modelling computer techniques that alresdy exist and the new ones that are continuously appearing are the result of a multidisciplinary exchange of ideas. Within this area, objects with changing shapes are inherently more difficult to model than rigid objects. Our main goal has been to provide a classification of the algorithms involved in the modelling of objects that can be as diverse as water, clothes, faces,...The classification has been made from the starting poing of inorganic and organic categories. Inorganic objects are classified according to their material state while the organic ones are classified according to the realm they belong to. Within each category, works are generally presented in chronological order, providing an extensive bibliography.
