Efficacy of lurasidone versus placebo in schizophrenia: a systematic review and meta-analysis of randomized controlled studies

Abstract

Radiometry relates to the physical aspects of radiant energy and the impact on cultural heritage, i.e. degradation. Radiation is considered in terms of thermal emission from bodies (infrared radiation), in the visible band, or as ultraviolet radiation. All sources of light, either natural or artificial light, are considered. Solar light is related to astronomic motions of the sun and irradiation on vertical, horizontal, or tilted surfaces, at any orientation. Sunlight penetrating through windows and its changeable colour is also considered. Exhibition lighting, types of electrical light sources (e.g. incandescent, halogen, metal halides, fluorescent, solid-state light-emitting diode), and their use for exhibition and restoration purposes are discussed within the conservation and biological colonization. Finally, how to improve the quality of light using optical filters for lamps and windows and optical fibres is also discussed.The degradation mechanisms caused by light, including overheating and drying, colour fading, convective motions, surface deposition and blackening, biological colonization development, and control of algae in damp environments are also considered.
