Abstract: The present invention relates to a synergistic pharmacological antibiofilm association of colistin and fosfomycin for use in the treatment of a bacterial infection caused by a biofilm-forming pathogen selected from A. baumannii, P. aeruginosa, S. maltophilia and K. pneumoniae strains, preferably in the biofilm phase of growth and, in particular infections associated with a respiratory tract disease, such as a chronic respiratory tract disease comprising CF, NCFB and COPD, especially in hospitalized patients.

Abstract: A method for correcting misalignment between test needles and test points during multiple electrical tests on printed circuit boards, in which setting up the machine to carry out the test on a circuit board or group of circuit boards, and hence correction of any misalignment, takes place without removing the circuit boards from the test area.

Abstract: An interface device for converting the test point grids of machines for electrically testing unassembled printed circuit boards to a lower density grid, to be interposed between the test machine grid (1) and the corresponding fixture (3). The interface device comprises a plurality of flat parallel plates (10, 11, 12, 13, 14) suitably perforated so that needles can pass through them, the plate (14) facing the grid (1) having the same perforation as the grid (1) and having some of its holes (21) unoccupied by said needles (15), whilst the outer plates (10, 11) have all the holes occupied by said needles (15), reproducing the desired lower density grid configuration.
