The present invention provides methods for producing composite particles using supercritical fluid as a plasticizing and extracting agent, composite particles formed in accordance with the methods and an apparatus for carrying out the methods. A bonded substrate stack having a porous layer is separated in two steps of the first and second processes. The ball is moveably positioned within the outer race such that the inside surface and the external surface slidably engage one another. Optical elements made with this optical glass are especially desirable in optical data transfer applications, particularly in read-write devices with movable read-write heads. The housing part is arranged to be attached on the outside of the wall of the package. The MAO inhibitors of the present invention can cause an increase in the level of norepinephrine, dopamine, and serotonin in the brain and other tissues, and thus can cause a wide variety of pharmacological effects mediated by their effects on these compounds.
