Abstract: A method of communication comprising the steps of: requesting at least one service having a plurality of parts; determining if said at least one service can be provided taking into account credit information relating to a user; and if not providing only one or some of said plurality of parts of said at least one service.

Abstract: Apparatus (8) for filtering, clarifying or polishing, a liquid flow containing finely divided solids. In the apparatus (8), the liquid flow to be filtered is directed to the outer surface of a filter element (3) with high speed and in tangential direction, and thereby, influenced by the generated shearing force, part of the liquid penetrates the filter element (3) and is filtered. More precisely, the apparatus (8) includes a cross-flow tube (2) having a circular cylindrical shape and having apertures directed substantially in tangential direction towards the outer surface of the filter element (3). A method for removing finely divided solids from a liquid flow using such apparatus is also described.

Abstract: A method of communication includes the step of requesting at least one service having a plurality of parts. The method also includes determining if the at least one service is providable by taking into account credit information relating to a user. If not, the method also includes providing only one or some of the plurality of parts of the at least one service.

Abstract: A pharmaceutical composition containing a microemulsion made up of a hydrophilic component, a lipophilic component, a surfactant and a drug, where the hydrophilic component, the lipophilic component and the surfactant form, when examined on a macroscopic scale, a one-phase solution. The hydrophilic component is dispersed as colloidal droplets in the lipophilic component, or the lipophilic component is dispersed as colloidal droplets in the hydrophilic component. According to still another alternative, the hydrophilic and the lipophilic components form a microemulsion with bicontinuous structure where the components form elongated adjacent channels. The drug is dissolved in the dispersed component or, in the case of a microemulsion with bicontinuous structure, in the hydrophilic or the lipophilic component. The microemulsion is stabilized by means of the surfactant. It is characteristic that a gelatinizer and water are added to the microemulsion thereby bringing the microemulsion into a gel form.
