Der (Sumerian: ^ALUDi-e-ir) was a Sumerian city-state at the site of modern Tell Aqar near al-Badra in Iraq's Wasit Governorate. It was east of the Tigris River on the border between Sumer and Elam. Its name was possibly Durum.

History

Der was occupied from the Early Dynastic period through Neo-Assyrian times. The local deity of the city was named Ishtaran, represented on Earth by his minister, the snake god Nirah. In the late 3rd millennium, during the reign of Sulgi of the Third Dynasty of Ur, Der was mentioned twice. The Sulgi year name 11 was named "Year Ishtaran of Der was brought into his temple", and year 21 was named "Year Der was destroyed". In the second millennium, Der was mentioned in a tablet discovered at Mari sent by Yarim-Lim I of Yamhad; the tablet includes a reminder to Yasub-Yahad king of Der about the military help given to him for fifteen years by Yarim-Lim, followed by a declaration of war against the city in retaliation for what Yarim-Lim described as evil deeds committed by Yasub-Yahad.

DDT

DDT (dichlorodiphenyltrichloroethane) is a colorless, crystalline, tasteless and almost odorless organochloride known for its insecticidal properties. DDT has been formulated in almost every conceivable form, including solutions in xylene or petroleum distillates, emulsifiable concentrates, water-wettable powders, granules, aerosols, smoke candles and charges for vaporizers and lotions.

First synthesized in 1874, DDT's insecticidal action was discovered by the Swiss chemist Paul Hermann Müller in 1939. It was then used in the second half of World War II to control malaria and typhus among civilians and troops. After the war, DDT was made available for use as an agricultural insecticide and its production and use duly increased. Müller was awarded the Nobel Prize in Physiology or Medicine "for his discovery of the high efficiency of DDT as a contact poison against several arthropods" in 1948.

In 1962, the book Silent Spring by American biologist Rachel Carson was published. It cataloged the environmental impacts of indiscriminate DDT spraying in the United States and questioned the logic of releasing large amounts of potentially dangerous chemicals into the environment without a sufficient understanding of their effects on ecology or human health. The book claimed that DDT and other pesticides had been shown to cause cancer and that their agricultural use was a threat to wildlife, particularly birds. Its publication was a seminal event for the environmental movement and resulted in a large public outcry that eventually led, in 1972, to a ban on the agricultural use of DDT in the United States. A worldwide ban on its agricultural use was later formalized under the Stockholm Convention on Persistent Organic Pollutants, but its limited use in disease vector control continues to this day and remains controversial, because of its effectiveness in reducing deaths due to malaria, which is countered by environmental and health concerns.

DDT (professional wrestling)

In professional wrestling a DDT is any move in which the wrestler has the opponent in a front facelock/inverted headlock, and falls down or backwards to drive the opponent's head into the mat. The classic DDT is performed by putting the opponent in a front facelock and falling backwards so that the opponent is forced to dive forward onto his or her head. Although widely credited as an invention of Jake Roberts, who gave the DDT its famous name, the earliest known practitioner of the move was Mexican wrestler Black Gordman, who frequently performed it during the 1970s.

Rumors abound as to what the letters DDT supposedly stood for, including Drape Drop Takedown, Drop Dead Twice, Demonic Death Trap, Drop Down Town, Death Drop Technique and Damien's Dinner Time or Damien's Death Touch (the latter two named after Jake's pet python Damien). When asked what DDT meant, Jake once famously replied "The End." The abbreviation itself originally came from the chemical dichloro-diphenyl-trichloroethane, a notorious pesticide, as stated during shoot interviews and Jake's Pick Your Poison DVD. Many think that the term DDT was applied because the chemical DDT is a hazardous chemical buried in the ground which potentially causes brain damage.

Denkmäler deutscher Tonkunst

Denkmäler deutscher Tonkunst (literally "Monuments of German musical art") is a historical edition of music from Germany, covering the Baroque and Classical periods.

The edition comprises two series: the first appeared in sixty-five volumes between 1892 and 1931, and the second, which was subtitled Denkmäler der Tonkunst in Bayern (Monuments of musical art in Bavaria), in thirty-six volumes between 1900 and 1931. The first series was issued by a Prussian royal commission of celebrity musicians and musicologists in instalments through the music publishers Breitkopf & Härtel in Leipzig, and the second by the Society for the Publication of Monuments of Musical Art in Bavaria.

A parallel series of volumes on Austrian composers, Denkmäler der Tonkunst in Österreich (Monuments of musical art in Austria), was begun in 1959, and as at 2015-10-25 is in progress at one hundred and fifteen volumes.
