Binder mixture comprising a hydroxyl-containing compound, and at least 1. In particular, the present invention provides vaccines that provide active immunity which comprise a polypeptide or DNA vaccine that contains or expresses at least one epitope of an antigen that has an amino acid sequence substantially similar to a unique 16 kDa antigen andor 30 kDa antigen of Sarcocystis neurona. The volume rendering system includes a plurality of parallel processing pipelines. The lower-yoke iron core assembling tank is connected at the opening portion which is opened when the lower-yoke iron core is housed in the lower-yoke iron core assembling tank. The interior housing may be buoyant, enabling it to float to the top of a liquid environment if it becomes separated during use. The supporting members are made stationary in predetermined positions of the main body, and a developing nip between the photoconductive drum and the developing roller is controlled as the toner cartridge is moved linearly with respect to the supporting member within a predetermined distance range.
