A sustained release drug carrier comprises a ceramic composite which is formed by bonding a plurality of ceramic bodies together, and drugs impregnated into the ceramic composite. In particular, the systems and methods herein described transmit and receive ultraviolet radiation having a wavelength within the solar blind region from a plurality of sensing nodes arranged both in a LOS network, which communicates via LOS communication, and in a NLOS network, which communicates via NLOS communication. The facility further includes a rendering subsystem that is distinct from the publishing subsystem and that, when applied to content, renders the content. Sealing bodies are arranged in recesses provided on faces of the webs or blades.
