Dermatologic Clinics, 1986
A wide variety of artificial light sources exists for use in the diagnosis and treatment of photosensitivity disorders. A discussion of the advantages and disadvantages of these light sources (including gas discharge arcs, fluorescent lamps, and other apparatus) illustrates the importance of matching the emission spectrum of the light source, the ...

Artificial Light‐Gated Catalyst Systems
Angewandte Chemie International Edition, 2010AbstractHaving control over an entity or even an entire process is arguably the ultimate demonstration of its understanding and it will enable its potential to be fully exploited. With this in mind, chemists have not only been creating and optimizing a myriad of different catalysts for most (relevant) chemical reactions over the past decades, but have ...

Arthur Engelbert and the participating artists use light hikes, different forms of meditation and thematically changing, acoustic and visual works of art to show how much time, space and art are interconnected. The idea of artificial light in its composite form develops at three artistic events in Sicily: each time at the solstice on June 21 ...

Artificial Light‐Driven Ion Pumps
Chemistry – A European JournalAbstractNature's molecular machinery has long provided inspiration for the development of functional materials, with natural ion pumps exemplifying the efficient conversion of solar energy into directional ion transport. This process is crucial for cellular signaling, bioenergy conversion, and photosynthesis.

Artificial light and nicotine subsensitivity
Biological Psychiatry, 1988Seasonal affective disorder (SAD) is a syndrome marked by recurrent depressions that generally occurinthefallorwinter(Rosenthaletal. 1984). This syndrome reportedly responds to daily treatment with 2-6 hr of bright artificial light (James et al. 1982; Lewy et al. 1982; Rosenthal et al. 1984, 1986; Wehr et al. 1986).

ARTIFICIAL LIGHT THERAPY IN TUBERCULOSIS
JAMA: The Journal of the American Medical Association, 1924The curative role of light in rickets and tetany is now commonly accepted. Under the influence of light, the blood in rickets shows an increased phosphorus content, and calcium deposition in the epiphyses of the long bones readily takes place. The blood in tetany shows an increased calcium and phosphorus content and, clinically, the disappearance of ...

HELIOTHERAPY AND ARTIFICIAL LIGHT
Journal of the American Medical Association, 1928The various points dealt with in this paper are intended mainly as a public answer to some of the questions put most frequently to me by foreign colleagues who have visited me at the Finsen Medical Light Institute in Copenhagen. These questions may be thus summarized: What sort of light is best, and what is the most efficient type of lamp?
