Abstract: The present invention discloses the method of making and using a novel, non-infective, paramyxovirus vaccine. Paramyxovirus structural proteins within a virus-like particle (VLP) comprise one example of such a vaccine. It is observed that the presence of matrix protein, alone, is sufficient and necessary to provide an effective VLP release. Co-expression of four paramyxovirus structural proteins, however, result in the release of non-infective VLPs with densities and efficiencies of release similar to that of infective particles. Representative diseases wherein a VLP vaccine might be useful include, but are not limited to, Newcastle disease, measles, respiratory syncytial virus infection, and parainfluenza 3 virus infection.

Abstract: A reactor, system and method for producing hydrogen features a reactor containing a heating stream channel and a hydrogen channel with a reaction channel positioned there between. A heat transfer sheet separates the heating stream channel and the reaction channel and a porous support plate separates the reaction channel and the hydrogen channel. A membrane constructed from palladium, vanadium, copper or alloys thereof covers the porous support plate. The heating stream channel receives a heating stream so that heat is provided to the reaction channel through the heat transfer sheet. A catalyst is positioned in the reaction channel and the reaction channel receives a reaction stream including a mixture of supercritical water and a hydrocarbon fuel so that hydrogen is produced in the reaction channel and is passed through the membrane into the hydrogen channel. The hydrogen separation may alternatively be accomplished in a separator device distinct from the reactor via either a membrane or pressure swing adsorption.
