Abstract: What are proposed are microcapsules comprising (a) a core comprising at least one active, and (b) a capsule wall, wherein the capsule wall consists of at least three polymer layers and at least one of the polymer layers consists of a first phenolic resin, wherein the first phenolic resin comprises 3% to 50% by weight of moieties that derive from at least one aromatic polyol, and at least one further polymer layer consists of a second phenolic resin, wherein the second phenolic resin comprises 3% to 50% by weight of moieties that derive from at least one triphenol.

Abstract: Means and a computerized method for recommending items such as books and audio compact disks. For each item, a user profile includes ratings provided by users of the system. Unlike present recommendation systems, the user profiles do not include pre-computed similarity factors measuring similarity between users. Rather, when an advisee requests a recommendation, similarity measures are computed comparing the advisee to other users, and the similarity measures are associated with the other users. A subset of the users is selected, where the subset includes the users most similar to the advisee. A recommendation is made based on the ratings by the members of the selected subset.

Abstract: The invention relates to a method for producing microcapsules, comprising the following steps: (a) providing a first aqueous preparation containing at least one prepolymer; (b) providing a second non-aqueous preparation containing the active substance to be encapsulated; (c) mixing the aqueous and the non-aqueous phases in the presence of at least one emulsifier and/or stabilizer in order to form an emulsion; (d) polymerizing the at least one prepolymer contained in the emulsion from step (c) in order to obtain a dispersion of microcapsules that enclose the active substance; (e) hardening and cross-linking the microcapsules obtained in step (d); and optionally (f) removing the microcapsules from the dispersion and drying the microcapsules, the method being characterized in that the emulsion is formed in the presence of at least one 1,2-diol in step (c).
