The WELL Building standard was designed for "advancing health and well-being in buildings globally" [26] Part of the standard is the implementation of Credit 54: Circadian Lighting Design. Specific thresholds for different office areas are designated in order to achieve credits. Light is measured at 1.2 m above the finished floor for all areas.
Charles Demuth, Aucassin and Nicolette, oil on canvas, 1921. Precisionism was a modernist art movement that emerged in the United States after World War I.Influenced by Cubism, Purism, and Futurism, Precisionist artists reduced subjects to their essential geometric shapes, eliminated detail, and often used planes of light to create a sense of crisp focus and suggest the sleekness and sheen of ...
A circadian rhythm (/ s ər ˈ k eɪ d i ə n /), or circadian cycle, is a natural oscillation that repeats roughly every 24 hours.Circadian rhythms can refer to any process that originates within an organism (i.e., endogenous) and responds to the environment (is entrained by the environment).
A circadian clock, or circadian oscillator, also known as one’s internal alarm clock is a biochemical oscillator that cycles with a stable phase and is synchronized with solar time. Such a clock's in vivo period is necessarily almost exactly 24 hours (the earth's current solar day). In most living organisms, internally synchronized circadian ...
From the movement's inception, artists were incorporating into their work the latest technologies of the Southern California-based engineering and aerospace industries to develop sensuous, light-filled objects. [3] Turrell, who has spread the movement worldwide, summed up its philosophy in saying, "We eat light, drink it in through our skins." [4]
The best studied rhythm in chronobiology is the circadian rhythm, a roughly 24-hour cycle shown by physiological processes in all these organisms. The term circadian comes from the Latin circa, meaning "around" and dies, "day", meaning "approximately a day." It is regulated by circadian clocks.
This model proposed a circadian rhythm of photoperiodic photosensitivity in plants. As day length increases with the spring and summer seasons, for example, light hits a plant's photosensitive phase, triggering a physiological or behavioral response. The Bünning Hypothesis proposed that light has two functions for an organism: [15] 1.
Nyctinastic movements are associated with diurnal light and temperature changes and controlled by the circadian clock. It has been argued that for plants that display foliar nyctinasty, it is a crucial mechanism for survival; however, most plants do not exhibit any nyctinastic movements. [ 1 ]
