Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
The guitar was used in this state from approximately February 1977 until July 1977, when he put strips of masking tape around the body in a criss-crossing stripe pattern before repainting it white, creating the classic Frankenstrat paint scheme. [5] Van Halen put a Gibson decal on the headstock, emphasizing the "cross-pollination" between ...
Humans are sensitive to light with a short wavelength. Specifically, melanopsin is sensitive to blue light with a wavelength of approximately 480 nm. [19] The effect this wavelength of light has on melanopsin leads to physiological responses such as the suppression of melatonin production, increased alertness, and alterations to the circadian ...
Blue light is absorbed by the structural proteins, enzymes, and protein metabolites found in the lens. [9] The absorption of blue light creates yellow pigments in the lens's protein. The lens progressively darkens and turns yellow. [9] Blue light is absorbed by the lens, preventing blue light from reaching the retina at the back of the eye. [12]
The guitar had a Floyd Rose vibrato system, built by Ping, which lowers pitch only as the device plate sits on the body top (similarly to the Ernie Ball Music Man EVH model) but added a d-Tuna device on the low E-string, which allowed that string to be instantly tuned to and from D (a former design of this device, named "The Willie" [12] was ...
If left untreated, obstructive sleep apnea puts you at higher risk for hypertension, heart disease, type 2 diabetes, depression and even an early death, according to the American Academy of Sleep ...
"Eruption" starts with a short accompanied intro with Alex Van Halen on drums and Michael Anthony on bass.The highlight of the solo is the use of two-handed tapping. "Eruption" was played on the Frankenstrat, with an MXR Phase 90, an Echoplex, a Univox echo unit and a 1968 Marshall 1959 Super Lead tube amp.
Zoll Itamar, which makes the at-home testing device I used, as well as implantable nerve-stimulation hardware for central sleep apnea, is a $60,000, “platinum” partner in AASM’s Industry ...
