A daytime running lamp (DRL, also daytime running light) is an automotive lighting and bicycle lighting device on the front of a road going motor vehicle or bicycle. [1] It is automatically switched on when the vehicle's handbrake has been pulled down, when the vehicle is in gear, or when the engine is started, emitting white, yellow, or amber ...
The length of light exposure influences entrainment. Longer exposures have a greater effect than shorter exposures. [12] Consistent light exposure has a greater effect than intermittent exposure. [14] In rats, constant light eventually disrupts the cycle to the point that memory and stress coping may be impaired. [15]
Artificial light at night refers to any light source other than a natural light source. Sources of artificial light include LEDS and fluorescents. This particular light source has effect on the reproduction, immune function, metabolism, thermoregulation and body temperature of organisms that need light for their daily activity.
Representation of the stages of processing in a typical reaction time paradigm. Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations.
Chemiluminescence (also chemoluminescence) is the emission of light (luminescence) as the result of a chemical reaction, i.e. a chemical reaction results in a flash or glow of light. A standard example of chemiluminescence in the laboratory setting is the luminol test. Here, blood is indicated by luminescence upon contact with iron in hemoglobin.
Polysomnography (PSG) is a multi-parameter type of sleep study [1] and a diagnostic tool in sleep medicine.The test result is called a polysomnogram, also abbreviated PSG.The name is derived from Greek and Latin roots: the Greek πολύς (polus for "many, much", indicating many channels), the Latin somnus ("sleep"), and the Greek γράφειν (graphein, "to write").
Running lights may refer to: Lights on vehicles designed to increase visibility while moving - see: Daytime running lamp, for increased visibility of vehicles during the day; Automotive lighting, for running lights for cars; Bicycle lighting, for running lights for bicycles; Navigation light, for running lights for aircraft, ships and spacecraft
Daytime running light LEDs of an automobile. LED uses fall into five major categories: Visual signals where light goes more or less directly from the source to the human eye, to convey a message or meaning; Illumination where light is reflected from objects to give visual response of these objects
