The binder does not dissolve and the toxic compound dissolves slowly. The dissolving toxin leaves behind a porous film that allows the toxic compounds below the surface to dissolve. Type 2: soluble binder–soluble toxic compound. The binder slowly dissolves as the toxic compound dissolves and the...
The water flows in at high speed into the agitation chamber, whereupon crushed limestone in the chamber is rubbed against itself and against the inside of the drum, thus stimulating dissolving of the lime. From the agitation chamber, the water is taken out to a sedimentation chamber 20 which ...

The seduction is too strong. So we train again and again in less highly charged situations in which the urge is present but not so overwhelming. By training with everyday irritations, we develop the knack of refraining when the going gets rough. ...
The Freundlich isotherm applies to the situation where dye adsorption onto the fibre is not limited by a number of specific adsorption sites and the fibre does not become saturated with dye. A typical system is one for which the dye ion and the fibre surface have the same type of electrical...
A monoclonal anti-human platelet antibody, TP82, is described, which caused irreversible aggregation of platelets in association with the release of adenosine triphosphate or [14C] serotonin, and which inhibited ristocetin-induced agglutination. Immunofluorescence assay showed that the antibody binds to ...
