The present invention relates to an inbred sunflower line, designated 503AB. The package also includes a flexible sheet defining a cavity for receiving the substance between the stiff sheet and the flexible sheet. When borderless printing is executed on the edges of printing medium, ink is ejected to lie off printing medium and then received in the ink receiver. The antigens are useful as diagnostic reagents in diagnostic methods and kits for determining infection of an individual with HEV. The magnetic multi-layered film includes a first ferromagnetic layer, second ferromagnetic layer and anti-ferromagnetic layer inserted between the first and second ferromagnetic layers. A process for the preparation of an injectable monophase hydrogel of at least one crosslinked polymer selected from polysaccharides and derivatives thereof.
