Abstract: The invention relates to a process for grinding cellulose ether comprising the steps of: a) grinding a cellulose ether comprising 20 to 90 wt % of water, based on the total weight of cellulose ether and water, and a cationic surfactant in a mill; and b) optionally drying the mixture while grinding, prior to or following the step of grinding.

Abstract: A system and a method for gathering customer data at a physical sales meeting premise. At least one RFID transponder is intended to be placed at the sales meeting premise. A customer data registration system includes storage for storing customer data, and element for compiling a digital material based on stored customer data, and a sender for sending the material to the customer. At least one portable unit includes an RFID reader and a communicator for communicating customer data to the customer data registration system. At least one contact input system includes an input for inputting customer data including an e-mail address and/or mobile phone number of a customer, and a communicator for communicating input customer data to the customer data registration system. Each portable unit is arranged to send customer data, which has been read from at least one RFID transponder, to the customer data registration system.

Abstract: The present patent application relates to a system and method for media distribution in a physical area (1). The system comprises at least one uniquely identifiable first type tag (2), which can be carried around said physical area (1) by a user being visitor thereto and at least one uniquely identifiable second type tag (3), identifying a media access point in said physical area (1). Further comprised in the system is an administrative system (4) and communication means (5, 7, 8). At least one of said first and second type tags (2, 3) has means (6) for identifying combinations of first and second type tags brought into close proximity of each other and communicate information relating to these tags to the administrative system (4). The administrative system (4) is arranged to respond to this information through distributing to communication means (7, 8) associated with either of these tags media determined by the received information.

Abstract: The present invention relates to the use of transgenic plants for the expression of vitamin B12 (cobalamin) binding proteins. Plant cells are transformed with nucleotide sequences adapted for expression and secretion of vitamin B12 binding proteins. The present invention also relates to the use of recombinant vitamin B12 binding proteins from plants in analytical tests and treatment of vitamin B12 deficiency. Also disclosed is a method for purification of recombinant vitamin B12 binding proteins.

Abstract: Apparatus is provided for controlling the degree of causticization of white liquor in its preparation from green liquor by the addition of calcium oxide, which comprises determining the sodium carbonate concentration of green liquor fed to the causticization; determining the sodium carbonate concentration of white liquor resulting from the causticization; and controlling the degree of causticization within a predetermined range while taking both sodium carbonate concentrations into account, so as to maintain the degree of causticization of the white liquor within the range despite variations in sodium carbonate concentration of the green liquor and variations in calcium oxide content of the calcium oxide added for causticization.
