    摘要： The invention relates to a dryer (1) for drying continuously conveyed products, e.g. a warp, comprising essentially a first dryer array (2) and a second dryer array (3). A passage (4) for passing through the product (W) is formed between the dryer arrays (2, 3). The second dryer array (3) is configured in such a way as to be able to move in relation to the first dryer array (2). When the dryer (1) is in stop position (S), the second dryer array (3) is disposed relative to the first dryer array (2) in such a way that the cross section of the passage (4) is bigger than in the operating position (B).

    摘要： The present invention relates to a microcarrier onto the surface of which a cationic compound has been immobilised via a guanidine group. The microcarrier is capable of attachment of cells, e.g. via charge-based interaction, and is advantageously used as a support in the culture of cells. Said compound may comprise one or two amino acids, such as arginine (Arg) or a dipeptide. The invention also relates to a method of preparing a polycationic microcarrier, which method comprises to immobilise a compound that comprises at least one guanidine group to an epoxide-activated substrate.

    摘要： A method for the manufacture of a solid porous separation material based on a polysaccharide, said method comprising the steps of: (a) providing an aqueous solution (I) of a polysaccharide, (b) solidifying the solution, preferably by transforming the solution to a gel, and (c) optionally cross-linking the polysaccharide, with the proviso that, if step (c) is present, steps (b) and (c) may be carried out simultaneously. The method is characterised in that the polysaccharide provided in step (a) is modified by being inter-molecularly cross-linked to an extent such that the viscosity of solution (I) is at least 110%, preferably at least 200%, of the viscosity of an aqueous solution (II) of the corresponding polysaccharide which has not been inter-molecularly cross-linked and which is present in the same concentration as the inter-molecularly cross-linked polysaccharide is in solution (I).

    摘要： A process for the production of a porous cross-linked polysaccharide gel and a gel obtainable by the following steps: a) preparing a solution or dispersion of the polysaccharide; b) adding a bifunctional cross-linking agent having one active site and one inactive site to the solution or dispersion from step a); c) reacting hydroxylgroups of the polysaccharide with the active site of the cross-linking agent; d) forming a polysaccharide gel; e) activating the inactive site of the cross-linking agent; f) reacting the activated site from step e) with hydroxylgroups of the polysaccharide gel, whereby cross-linking of the gel takes place. The cross-linked polysaccharide gel obtained can further be cross-linked by conventional methods, one or several times.
