Abstract: Elderly individuals are administered dosages of Trans-resveratrol totaling between about 250 mg and 1 gram per day. Typically about 500 mg of Trans-resveratrol are orally administered to such individuals on a daily basis. As a result of the chemical action of Trans-resveratrol in the bodies of the subjects, Alzheimer's disease is prevented, or if already present, advancement is retarded and the existing mentally debilitating conditions of Alzheimer's disease are treated. A subject receiving the Trans-resveratrol experiences a reduction or illumination of the effects of Alzheimer's disease.

Abstract: Reflected-transmitted non-converted and converted seismic waves as used for seismic imaging which is not limited by the angle of inclination of the seismic interfaces. These wave signals are recorded at the surface and are later used to obtain seismic imaging of geological discontinuities and the physical properties of the medium. Known duplex waves are used with transmitted waves for obtaining seismic images from much wider angles, ranging from horizontal to vertical. Two types of migration procedures are used: the first one being based on migration of transmitted compressional and converted duplex waves, and the second one being based on the joint migration of two interrelated fields, such as interferometric principles; for example, the first field of primary waves corresponding to the one time reflected monotypic compressional (non-converted) type of waves and a second wavefield corresponding to secondary waves of more complex origin, such as reflected waves and converted waves.
