Defender (association football)

In the sport of association football, a defender is an outfield player whose primary role is to prevent the opposing team from scoring goals.

There are four types of defenders: centre-back, sweeper, full-back, and wing-back. The centre-back and full-back positions are essential in most modern formations. The sweeper and wing-back roles are more specialised for certain formations.

Centre-back

A centre-back (also known as a central defender or centre-half) defends in the area directly in front of the goal, and tries to prevent opposing players, particularly centre-forwards, from scoring. Centre-backs accomplish this by blocking shots, tackling, intercepting passes, contesting headers and marking forwards to discourage the opposing team from passing to them.

With the ball, centre-backs are generally expected to make short and simple passes to their teammates, or to kick unaimed long balls down the field. For example, a clearance is a long unaimed kick intended to move the ball as far as possible from the defender's goal.

He initially gained recognition as the official DJ for Atlanta-based rapper T.I.. He is perhaps best known for hosting several mixtapes, most notably his successful Gangsta Grillz series. He is also known for doing the Dedication series with New Orleans-bred rapper Lil Wayne, with the New York Times calling Dedication 2, one of the "10 best recordings of 2006".

DJ Drama along with Khomotso Tibane and DJ Sense, founded Aphilliates Music Group, in 2003. The Aphilliates Music Group signed a joint venture deal with Asylum Records in 2006.

His second album was the sequel Gangsta Grillz: The Album (Vol. 2), which was released in May 2009, under Atlantic and Grand Hustle.

Human back

The human back is the large posterior area of the human body, rising from the top of the buttocks to the back of the neck and the shoulders. It is the surface opposite to the chest, its height being defined by the vertebral column (commonly referred to as the spine or backbone) and its breadth being supported by the ribcage and shoulders. The spinal canal runs through the spine and provides nerves to the rest of the body.

Structure

The central feature of the human back is the vertebral column, specifically the length from the top of the thoracic vertebrae to the bottom of the lumbar vertebrae, which houses the spinal cord in its spinal canal, and which generally has some curvature that gives shape to the back. The ribcage extends from the spine at the top of the back (with the top of the ribcage corresponding to the T1 vertebra), more than halfway down the length of the back, leaving an area with less protection between the bottom of the ribcage and the hips. The width of the back at the top is defined by the scapula, the broad, flat bones of the shoulders.

Back (song)

"Back" is a song co-written and recorded by American country rap artist Colt Ford. It is a duet with Jake Owen, and the second single from Ford's fourth studio album, Declaration of Independence.

Critical reception

Ashley Cooke of Roughstock gave it a full 5 stars, saying that the song "genuinely tugs at your heart -strings. If you were lucky enough to grow up with memories similar to the lyrics in this song, you will find yourself in love with it just as I did." Billy Dukes of Taste of Country gave it 2.5 stars out of 5, saying that it was "about a verse too long" and that it "isn't a step backward, but it's no step forward."

Skylab

Skylab was a space station launched and operated by NASA and was the United States' first space station. Skylab orbited Earth from 1973 to 1979, and included a workshop, a solar observatory, and other systems. It was launched unmanned by a modified Saturn V rocket, with a weight of 150,300 pounds (68,175 kg). Three manned missions to the station, conducted between 1973 and 1974 using the Apollo Command/Service Module (CSM) atop the smaller Saturn IB, each delivered a three-astronaut crew. On the last two manned missions, an additional Apollo / Saturn IB stood by ready to rescue the crew in orbit if it was needed.

The station was damaged during launch when the micrometeoroid shield separated from the workshop and tore away, taking one of two main solar panel arrays with it and jamming the other one so that it could not deploy. This deprived Skylab of most of its electrical power, and also removed protection from intense solar heating, threatening to make it unusable. The first crew was able to save it in the first in-space major repair, by deploying a replacement heat shade and freeing the jammed solar panels.

Skylab 3

Skylab 3 (also SL-3 and SLM-2) was the second manned mission to the first American space station, Skylab. The mission began July 28, 1973, with the launch of three astronauts on the Saturn IB rocket, and lasted 59 days, 11 hours and 9 minutes. A total of 1,084.7 astronaut-utilization hours were tallied by the Skylab 3 crew performing scientific experiments in the areas of medical activities, solar observations, Earth resources, and other experiments.

The manned Skylab missions were officially designated Skylab 2, 3, and 4. Mis-communication about the numbering resulted in the mission emblems reading Skylab I, Skylab II, and Skylab 3 respectively.
