Question: In 1955, DC Sinclair and G Weddell developed peripheral pattern theory, based on a 1934 suggestion by John Paul Nafe. They proposed that all skin fiber endings (with the exception of those innervating hair cells) are identical, and that pain is produced by intense stimulation of these fibers. Another 20th-century theory was gate control theory, introduced by Ronald Melzack and Patrick Wall in the 1965 Science article "Pain Mechanisms: A New Theory". The authors proposed that both thin (pain) and large diameter (touch, pressure, vibration) nerve fibers carry information from the site of injury to two destinations in the dorsal horn of the spinal cord, and that the more large fiber activity relative to thin fiber activity at the inhibitory cell, the less pain is felt. Both peripheral pattern theory and gate control theory have been superseded by more modern theories of pain[citation needed].

Answer: unanswerable
Question: The vast majority of devices containing LEDs are "safe under all conditions of normal use", and so are classified as "Class 1 LED product"/"LED Klasse 1". At present, only a few LEDsextremely bright LEDs that also have a tightly focused viewing angle of 8 or lesscould, in theory, cause temporary blindness, and so are classified as "Class 2". The opinion of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) of 2010, on the health issues concerning LEDs, suggested banning public use of lamps which were in the moderate Risk Group 2, especially those with a high blue component in places frequented by children. In general, laser safety regulationsand the "Class 1", "Class 2", etc. systemalso apply to LEDs.
Try to answer this question if possible: Which government advocated the banning of Class 2 LEDs?
Answer: French
Question: eSATA does not supply power to external devices. This is an increasing disadvantage compared to USB. Even though USB 3.0's 4.5 W is sometimes insufficient to power external hard drives, technology is advancing and external drives gradually need less power, diminishing the eSATA advantage. eSATAp (power over eSATA; aka ESATA/USB) is a connector introduced in 2009 that supplies power to attached devices using a new, backward compatible, connector. On a notebook eSATAp usually supplies only 5 V to power a 2.5-inch HDD/SSD; on a desktop workstation it can additionally supply 12 V to power larger devices including 3.5-inch HDD/SSD and 5.25-inch optical drives.
Try to answer this question if possible: On a notebook eSATAp usually supplies how much power?
Answer: 5 V to power a 2.5-inch HDD/SSD
Question: Because of space constraints, NARA opened a second facility, known informally as Archives II, in 1994 near the University of Maryland, College Park campus (8601 Adelphi Road, College Park, MD, 20740-6001). Largely because of this proximity, NARA and the University of Maryland engage in cooperative initiatives. The College Park campus includes an archaeological site that was listed on the National Register of Historic Places in 1996.
