摘要:
A process for the preparation of homo- and co-polymers of vinyl chloride by polymerization in seeded microsuspension, which comprises effecting polymerization in the presence of one or more seeding products in the form of dispersions of particles of polymers, the particles of at least one of the seeding products containing the initiator required for polymerization and said initiator being activated by an organosoluble metal complex and nitric acid.

The invention relates to fully human monoclonal antibodies, and fragments thereof, that bind to the chemokine Regulated upon Activation, Normal T-cell Expressed, and Secreted (RANTES, CCL5), thereby modulating the interaction between RANTES and one of more of its receptors, such as, e.g., CCR1, CCR3, CCR4 and CCR5, and/or modulating the biological activities of RANTES. The invention also relates to the use of these or any anti-RANTES antibodies in the prevention or treatment of immune-related disorders and in the amelioration of one or more symptoms associated with an immune-related disorder.

A television event may be consumed after been stored in a mass memory of a multimedia unit, but still fully relies on the security of a secure device. A conversion of a received content aims at firstly descrambling the content using control words included in entitlement control messages and immediately re-encrypting the descrambled content by a unique key generated specifically for this content. Access conditions attached to the entitlement control message containing the control word are temporarily stored and once the decryption is terminated, the secure device produces an information block. This information block containing for example access conditions and an identifier of the content is either stored into a secure memory of the secure device or stored in the mass memory with the encrypted content. The unique key is made up of a combination of a root key specific to the secure device and the information block.

Example embodiments relate to a security device having two communication interfaces sharing at least one pin, each interface being capable of operating according to either of two predetermined communication protocols. The security device may further include a frequency detector to detect the frequency of a clock signal on the shared pin. Depending on the value of the detected frequency, and to which of a plurality of predetermined frequency ranges the detected frequency pertains, the security device may function according to one of the two predetermined communication protocols, operating at two different frequencies.

The invention relates to fully human antibodies, and fragments thereof, that bind to interferon-inducible-protein-10 (IP-10, CXCL10), thereby modulating the interaction between IP-10 and its receptor, CXCR3, and/or modulating the biological activities of IP-10. The invention also relates to the use of such anti-IP-10 antibodies in the prevention or treatment of immune-related disorders and in the amelioration of one or more symptoms associated with an immune-related disorder.
摘要:
Micro-suspension polymerization of vinyl chloride monomers and comonomers with a seed in the form of a previously prepared dispersion of the polymer or copolymer containing all of the organo-soluble initiator required for the polymerization, in which the initiator is activated during the polymerization by the addition of an organo-metallic complex of a water-soluble metal salt reacted with a complexing agent.

摘要:
A method for protecting multimedia data exchanged between a multimedia processing device and a security module managed by a management center, the multimedia processing device receiving an encrypted multimedia data, decrypting the encrypted multimedia data and converting the decrypted multimedia data, said multimedia processing device including a personal key, the method comprising obtaining an identifier pertaining to an entity representing a group of multimedia processing devices, calculating a security key formed by a one-way function based on the personal key of the processing multimedia device and the entity identifier, transmitting this security key and the entity identifier to the security module connected to said multimedia processing device, calculating the security key using a one-way function based on the personal key of said multimedia processing device and the entity identifier, and using the calculated security key to secure the data exchanged between the multimedia processing device and the security module.
摘要:
The present invention is related to antibodies directed to the antigen CD3 and uses of such antibodies. In particular, the present invention provides fully human monoclonal antibodies directed to CD3. Nucleotide sequences encoding, and amino acid sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions and/or complementarity determining regions (CDR's), specifically from FR1 through FR4 or CDR1 through CDR3, are provided. Hybridomas or other cell lines expressing such immunoglobulin molecules and monoclonal antibodies are also provided.
摘要:
Example embodiments are directed to a digital audio/video (AV) data processing unit and a method of controlling access to the digital AV data. The processing unit of AV digital data includes a deciphering unit of the AV data, a decompression unit, an input/output interface of the processed AV data and communication device towards a security module. The deciphering and decompression units respectively include an encryption unit and a decryption unit, each having at least one personal key and a common encryption key. Deciphering the AV data using the control words and re-encrypting the deciphered AV data occurs only after a successful verification of the control word and the common key. After temporary storage, the re-encrypted AV data cannot be decrypted by the decryption unit unless the common key has been positively verified by the security module by way of a random number generated by the decryption unit.
