Abstract: An ingestible capsule is provided. The capsule comprises a shell container containing an ultraviolet emitter, and an energy source connected to the emitter. The capsule also comprises a gelatinous layer encasing the shell container. After ingestion, ultraviolet rays emitted by the emitter reach gastric areas hosting bacteria afflicting an ingesting user, the rays at least partially eradicating the bacteria.

Abstract: This invention relates to a self-supporting three-dimensional prestressed structure, as well as a method and a device for erecting same, to be employed in the construction of residential and nonresidential buildings. The structure is constructed of vertical form-defining flexible rodlike members (1) stressed during the construction of the structure, as well as horizontal flexible rodlike members (2) each forming a closed curve. The horizontal members (2) are also stressed during construction and welded or rigidly affixed by other means to the vertical form-defining members (1). Instead of horizontal circular members (2) the structure can be constructed completely or to some extent using a spiral member, also stressed during the construction of the structure that is rigidly affixed to the vertical form-defining flexible members (1).
