Abstract: The present invention relates to a Ljungan virus with improved replication characteristic and the use of this Ljungan virus, amongst other thing, in the production of a vaccine.

Abstract: The present invention relates to a new group of Ljungan viruses, proteins expressed by the viruses, antibodies to the viruses and proteins, vaccines against the viruses, diagnostic kits for detecting the viruses, uses of the viruses, proteins, antibodies and vaccines in therapy, uses of the viruses, proteins, antibodies and vaccines in treating diseases caused by the viruses and methods of treatment for treating diseases caused by the viruses.

Abstract: An improved circular saw blade designed for cutting fiber cement workpieces, which are becoming more and more prevalent on the construction site, includes a PCD/carbide tip mounted in the rim of a saw blade at six, rather than the usual four locations, equally spaced around the blade. The tips are mounted adjacent a relatively large-diameter, semi-circular gullet, which itself is preceded by a chip and dust minimizer. The minimizer includes several alternating hills and valleys formed in the rim of the saw blade, each hill and valley having the same radius, producing a sinuous array essentially centered on the rim of the blade. It has been discovered that such a dust and chip minimizer reduces the level of dust and chips produced by the blade and clears the same from the kerf generated in the blade-workpiece interface.

Abstract: The present invention relates to a new family of viruses within the Picornavirus family. The present invention also relates to an isolated nucleic acid from said virus or fragments of said nucleic acid. The present invention also relates to an isolated protein of said virus or an immunogenic fragment thereof. The invention also relates to antibodies or antigen-binding fragments of such antibodies directed against said virus. The present invention also relates to diagnostic kits. The present invention also relates to a method of detecting the presence of said virus in a subject suspected of having a viral infection.
