Abstract: The present invention provides a process improvement related to the conjugation of capsular polysaccharides from Streptococcus pneumoniae (S. pneumoniae) serotype 35B to a carrier protein. The serotype 35B polysaccharide-protein conjugate, prepared by the disclosed process, is, among other things, more immunogenic than similar conjugates made by prior art methods. S. pneumoniae serotype 35B polysaccharide-protein conjugates prepared using the processes of the invention can be included in multivalent pneumococcal conjugate vaccine compositions.

Abstract: A prefabricated wall (100) being modular is described, comprising at least one module (1) comprising at least one sheet layer (2) adapted to mount at least one panel (5) by means of fixing means (6) and a supporting frame (3), which supports said at least one module (1), said supporting frame (3) is a frame delimiting a through opening (30) which mounts said at least one sheet layer (2) which is a plate sheet comprising a multiplicity of through openings (20) and a multiplicity of through slots (25) adapted to be traversed by a fixing mean (6) up to an engagement position of said fixing mean (6) with said at least one sheet layer (2) in order to mount said at least one panel (5).

Abstract: A display having a modular element structure, including a tubular upright provided with a base and having at least one recess, pointed in at two longitudinally separate portions embracing the upright, each of the portions being provided with a projection complimentary to the recess, a threaded band of one portion meeting with a threaded band of the other portion when these are combined to form the collar, and then outwardly projecting lower band. The display also includes a tubular sleeve mountable over the collar from above and resting on all of the projecting band via a complimentary portion, the height of the sleeve being such as to leave the threaded band upwardly free, a plurality of beams fixed at least one end and an end piece which is provided with a device for hooking it to the tubular sleeve, and the ring nut which screws on to the threaded portion of the collar positions it so as to lock the end piece of the beam to the sleeve.
