Abstract: The subject matter of this specification can be embodied in, among other things, a rotary mixer with a housing defining a mixing chamber defining a rotation axis, the housing being rotatable about the rotation axis in a rotation direction and having a longitudinal midpoint, a set of blades within the housing, wherein at least one pair of blades of the set of blades forms an angle with respect to each other, and at least one blade of the set of blades is shorter than another blade of the set of blades in the rotation direction, and a splitter blade located within the housing with respect to the longitudinal midpoint and the angle to divide material in the mixing chamber between the at least one blade of the set of blades and the other blade of the set of blades, as the cylindrical housing is rotated about the rotation axis.

Abstract: Vaccines containing herpes simplex virus (HSV) VP22 polypeptides capable of eliciting a cellular immune response and methods for treating and preventing HSV infections using the vaccines are disclosed. The vaccines can include additional HSV polypeptides, such as HSV glycoproteins. Also disclosed are methods of DNA immunization.

Abstract: A dual shear mixing element for use in a chemical reactor. The device may be used in processes where liquids of different temperatures need to be thoroughly mixed in a short period of time and solute must stay in solution. The present invention is particularly useful in the solution polymerization of polyolefins, especially in the medium pressure process for the preparation of linear low density polyethylene.
