The invention provides truncated HCV NS5 polypeptides and fusion proteins comprising the truncated NS5 polypeptides, fused to at least one other HCV epitope derived from another region of the HCV polyprotein. The LED light source is capable of greatly increasing the light emitting efficiency and reducing the cost and complexity of the heat dissipation construction. The bodies of these frames having interengaging registering means extending continuously therearound. A distance between the first and second conveying roller pairs is shorter than a length of a minimum size sheet in a conveying direction. The plant parts and natural extracts result in a reduction of lesion score, oocysts per gram of fecal matter and mortality.
