Abstract: A ballistic correction device for sight members (of weapons) provided with an elevation adjustment turret is described. In particular, the device comprises detecting means, outside of the turret, to detect the rotations imparted by the shooter to the adjustment ring of the elevation turret, and displaying means to display the shooting distance and/or other shooting settings corresponding to the position the ring assumed. The device displays, for the shooter, the calibration of the turret from the moment the shooter observes the device. The shooter is no longer required to keep in mind the last calibration carried out. In the step of carrying out a new calibration, it is no longer necessary to consult the compensation tables, but simply to read the values displayed on the device as the ring of the turret is being rotated. A method for correcting the elevation of the weapon is further described.

Abstract: An in vitro method and a kit for the quantification of antibodies anti-beta amyloid protein in a sample of cerebrospinal fluid comprising the following steps a) concentrating the quantity of said antibodies of said sample with magnetic micro beads coated with macromolecules capable of binding said antibodies b) analysing the concentrated sample obtained in step a) by immunoenzyme assay or by radioimmunoassay; c) analysing a sample comprising antibodies anti-beta amyloid protein having a known titre with the same assay used in step b) and elaborating the related calibration curve, wherein said antibody having a known titre is a murine antibody belonging to the IgG2a or IgG2b class or a human or humanized antibody belonging to the IgG2b or IgGi class.
