Nap

A nap is a short period of sleep, typically taken during daylight hours as an adjunct to the usual nocturnal sleep period. Naps are most often taken as a response to drowsiness during waking hours. Cultural attitudes toward napping during the work day vary. In many Western cultures, children and the elderly are expected to nap during the day and are provided with designated periods and locations to do so. In these same cultures, most working adults are not expected to sleep during the day and napping on the job is widely considered unacceptable. Other cultures (especially those in hot climates) serve their largest meals at midday, with allowance for a nap period (siesta) afterwards before returning to work.

Benefits

Napping was found to be both physiologically and psychologically beneficial. Napping for 20 minutes can help refresh the mind, improve overall alertness, boost mood and increase productivity. Napping may benefit the heart. In a six-year study of Greek adults, researchers found that men who took naps at least three times a week had a 37 percent lower risk of heart-related death.

Nap (textile)

Primarily, nap is the raised (fuzzy) surface on certain kinds of cloth, such as velvet. Nap can refer additionally to other surfaces that look like the surface of a napped cloth, such as the surface of a felt or beaver hat.

Starting around the 14th century, the word referred originally to the roughness of woven cloth before it was sheared. When cloth, especially woollen cloth, is woven, the surface of the cloth is not smooth, and this roughness is the nap. Generally the cloth is then 'sheared' to create an even surface, and the nap is thus removed. A person who trimmed the surface of cloth with shears to remove any excess nap was known as a shearman.

Piled nap

Since the 15th century, the term nap generally refers to a special pile given to the cloth. The term pile refers to raised fibres that are there on purpose, rather than as a by-product of producing the cloth. In this case, the nap is woven into the cloth, often by weaving loops into the fabric, which can then be cut or left intact. Carpets, rugs, velvet, velour, and velveteen, are made by interlacing a secondary yarn through woven cloth, creating a nap or pile.

Tankcsapda

Tankcsapda is a Hungarian heavy metal and hard rock band.

History

Tankcsapda was formed in 1989, in Debrecen, Hungary. The group started off as a power trio with only drums, bass and guitar playing punk rock, but continuously expanded their repertoire with different elements of rock music. They initially performed in small venues and published their album on small independent labels. The band's first important commercial development came in 1995, with the release of their fourth album, Az Ember Tervez (Man Proposes), which has become the first gold record for Tankcsapda.

In 2003, they finally crossed over to the mainstream, with the release of their Élni vagy Égni (To Live or to Burn) album, and two singles off this record: "Be Vagyok Rúgva" ("I'm Drunk") and "Örökké Tart" ("Lasts Forever"). After the mainstream-breaking album of 2003 and the very successful compilation album that followed, they took a left turn and released one of their heaviest albums to date, Mindenki Vár Valamit (Everyone's Waiting for Something), succeeded by a live album Elektromágnes (Electromagnet). Their newest album, released in October 2009, is Minden Jót (Best Wishes).
