A device for opposing sloshing in a flexible tank provided with a top cushion and having a bottom and a plurality of sides, the device includes at least first and second ties. The two electrical paths are created by connecting the first transmission line to a first via which is in turn connected to a second via having a second transmission line with a plurality of connecting electrical paths between the two vias. The first beam and orthogonal beam are converted into electrical signals before a differential comparison of the signals is performed to detect a desired chiral species within the chiral mixture. The server includes a position calculation module that calculates the position of the node based on the time information transmitted from the base station. Methods of the invention are disclosed to be used in assessing a risk of pelvic organ prolapse development, estimating an extent of pelvic floor organ traumatic damage after childbirth and estimating an improvement after an interventional procedure. Humidity of the ambient atmosphere of the antibody is controlled so that the antibody becomes active.
