Alcohol

In chemistry, an alcohol is any organic compound in which the hydroxyl functional group (–OH) is bound to a saturated carbon atom. The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), the predominant alcohol in alcoholic beverages.

The suffix -ol appears in the IUPAC chemical name of all substances where the hydroxyl group is the functional group with the highest priority; in substances where a higher priority group is present the prefix hydroxy- will appear in the International Union of Pure and Applied Chemistry (IUPAC) name. The suffix -ol in non-systematic names (such as paracetamol or cholesterol) also typically indicates that the substance includes a hydroxyl functional group and, so, can be termed an alcohol. But many substances, particularly sugars (examples glucose and sucrose) contain hydroxyl functional groups without using the suffix. An important class of alcohols, of which methanol and ethanol are the simplest members is the saturated straight chain alcohols, the general formula for which is C_nH_2n+1OH.

Alcohol (Barenaked Ladies song)

"Alcohol" is a song by the Alternative rock group Barenaked Ladies released as the last single and sixth track on their 1998 album Stunt. Although it did not chart on the Billboard Hot 100 or the UK Singles Chart, it received some airplay on the US Modern Rock Tracks charts, peaking at #33 on the chart. The song looks at alcohol abuse, and moderation, using a sarcastic undertone. As part of the band's tradition involving one song per album, "Alcohol" was recorded naked.

It was nominated for two Grammys: Best Country Song and Best Country Male Vocal. Joseph Gordon-Levitt covered it in 2011.

The song is a mid-tempo in 6/8 time signature and the key of C major. In the song, Paisley personifies alcoholic beverages in general, describing the various influences that the beverages have on certain people ("Helping white people dance"), ultimately stating "You'll have some of the best times you'll never remember, with me, Alcohol".

DF-15

The Dong-Feng 15 (a.k.a. DF-15, M-9, CSS-6) is a short-range ballistic missile developed by the People's Republic of China. The DF-15 and the newer DF-16 are thought to be the only non-nuclear missiles in use by the People's Liberation Army Second Artillery Corps. The U.S. Department of Defense estimated in 2008 that China had 315-355 DF-15 missiles and 90-110 launchers.

History

Development on the DF-15 began in 1985 with a finalized design proposal being approved by the PLA in 1987. From the late 1980s to the mid-1990s, testing of the missile was done in the Gobi Desert. The first public display of the missile took place at the Beijing Defense Exposition in 1988. The SAC had allegedly deployed a small number of the missiles the following year.

Description

The DF-15 uses a solid fuel, single-stage rocket. It is vertically launched from an eight-wheeled transporter erector launcher (TEL). The missile's trajectory is guided using small thrusters and an inertial guidance system on the warhead. The warhead is only a tenth of the size of the missile body. After the body and warhead separate, the body trails behind to camouflage the warhead. The terminal velocity of the missile is over Mach 6.

DF-21

The Dong-Feng 21 (DF-21; NATO reporting name CSS-5 - Dong-Feng (Chinese: 东风; literally: "East Wind")) is a two-stage, solid-fuel rocket, single-warhead medium-range ballistic missile (MRBM) in the Dong Feng series developed by China Changfeng Mechanics and Electronics Technology Academy. Development started in the late 1960s and was completed around 1985-86, but it was not deployed until 1991. It was developed from the submarine-launched JL-1 missile, and is China's first solid-fuel land-based missile. The U.S. Department of Defense in 2008 estimated that China had 60-80 missiles and 60 launchers.

Originally developed as a strategic weapon, the DF-21's later variants were designed for both nuclear and conventional missions. As well as a nuclear warhead of around 300 kt, it is thought that high explosive and submunition warheads are available. The latest DF-21D was said to be the world's first anti-ship ballistic missile (ASBM). The DF-21 has also been developed into a space-capable anti-satellite weapon/anti-missile weapon carrier.
