Abstract: The invention relates to a dishwashing additive or detergent composition comprising a silicate source and a ring-containing organic acid; wherein the additive composition comprises between 20 mg and 5000 mg of silicate source and/or between 50 mg and 10,000 mg of ring-containing organic acid compound; and wherein the composition comprises a ratio of between 1 part silicate source to 4 parts ring-containing organic acid compound and 4 parts silicate source to 1 part ring-containing organic acid compound. The composition provides aluminium and aluminium alloy protection benefits. The invention further relates to packages and devices containing the compositions and to methods of washing dishes in an automatic dishwasher using the compositions.

Abstract: Piston ring for an internal combustion engine, comprising a running surface, and upper and a lower flank surface and an inner circumferential surface, wherein at least one of said surfaces is provided with at least one marking which is formed in the manner of a matrix, characterized in that the surface region which contains the marking is of brighter configuration in order to produce a background surface for the matrix than the surface regions of the piston ring which immediately adjoin in at least outside the matrix.

Abstract: Provided is a use of a recombinant chimaeric protein as an immunogen in a process for producing a monoclonal antibody, wherein the recombinant chimaeric protein is assembled into a virus-like particles, and includes a foreign protein or peptide or a fragment thereof.

Abstract: Certain aspects of a method and system for protecting data during mobile communication may comprise a mobile multimedia processor that decrypts an encrypted algorithm in hardware within the mobile multimedia processor. The mobile multimedia processor may be adapted to utilize the decrypted algorithm to decrypt data in software. The mobile multimedia processor may be adapted to decrypt instructions for the encrypted algorithm as the instructions enter an instruction cache. The mobile multimedia processor may be adapted to protect the decrypted data by performing a hash operation of the decrypted data and check a result of the hash operation.
