Saudi Arabia

Saudi Arabia (ⁱ/ˌsɔːdiː əˈreɪbiə/, ⁱ/ˌsaʊ-/), officially known as the Kingdom of Saudi Arabia (KSA), is an Arab state in Western Asia constituting the bulk of the Arabian Peninsula. With a land area of approximately 2,150,000 km² (830,000 sq mi), Saudi Arabia is geographically the second-largest state in the Arab world after Algeria. Saudi Arabia is bordered by Jordan and Iraq to the north, Kuwait to the northeast, Qatar, Bahrain, and the United Arab Emirates to the east, Oman to the southeast, and Yemen to the south. It is the only nation with both a Red Sea coast and a Persian Gulf coast, and most of its terrain consists of arid inhospitable desert or barren landforms.

The area of modern-day Saudi Arabia formerly consisted of four distinct regions: Hejaz, Najd, and parts of Eastern Arabia (Al-Ahsa) and Southern Arabia ('Asir). The Kingdom of Saudi Arabia was founded in 1932 by Ibn Saud. He united the four regions into a single state through a series of conquests beginning in 1902 with the capture of Riyadh, the ancestral home of his family, the House of Saud. The country has since been an absolute monarchy, effectively a hereditary dictatorship governed along Islamic lines. The ultra-conservative Wahhabism religious movement within Sunni Islam has been called "the predominant feature of Saudi culture", with its global spreading largely financed by the oil and gas trade. Saudi Arabia is sometimes called "the Land of the Two Holy Mosques" in reference to Al-Masjid al-Haram (in Mecca), and Al-Masjid an-Nabawi (in Medina), the two holiest places in Islam. The Kingdom has a total population of 28.7 million, of which 20 million are Saudi nationals and 8 million are foreigners.

Saudia Flight 163

Saudia Flight 163 was a scheduled passenger flight of Saudia that caught fire after takeoff from Riyadh International Airport (now the Riyadh Air Base) on a flight to Jeddah, Saudi Arabia on Tuesday, 19 August 1980. All 287 passengers and 14 crew on board the Lockheed L-1011-200 TriStar, registration HZ-AHK, died after the aircraft made an emergency landing back at the Riyadh airport.

At the time, the accident was the second deadliest single aircraft disaster in history, after Turkish Airlines Flight 981. It's the sixth deadliest aircraft disaster overall, after the Tenerife airport disaster, Japan Airlines Flight 123, the Charkhi Dadri mid-air collision, Turkish Airlines Flight 981, and Air India Flight 182. It was also the highest death toll of any aviation accident in Saudi Arabia and the highest death toll of any accident involving a Lockheed L-1011 TriStar anywhere in the world. It is also the deadliest aviation disaster that did not involve a crash on impact or mid-flight break up.

Saudi 2

Saudi TV Channel 2 (KSA 2), or as of 2014 known as Saudi 2 is the English news and entertainment TV channel of Saudi Arabia.

Established in 1964, the channel produces programmes focusing on cultural, political, and economic issues aimed at expatriates living in Saudi Arabia. Following its conversion to a 24-hour channel it expanded its broadcasting to Europe and North America in the middle of 2007 and now employs a large network of news correspondents based in the Middle East, the United Kingdom and the United States.

Hip hop music

Hip hop music, also called hip-hop or rap music, is a music genre formed in the United States in the 1970s that consists of a stylized rhythmic music that commonly accompanies rapping, a rhythmic and rhyming speech that is chanted. It developed as part of hip hop culture, a subculture defined by four key stylistic elements: MCing/rapping, DJing/scratching, break dancing, and graffiti writing. Other elements include sampling (or synthesis), and beatboxing.

While often used to refer to rapping, "hip hop" more properly denotes the practice of the entire subculture. The term hip hop music is sometimes used synonymously with the term rap music, though rapping is not a required component of hip hop music; the genre may also incorporate other elements of hip hop culture, including DJing, turntablism, and scratching, beatboxing, and instrumental tracks.

Rap GTP-binding protein

Rap GTP-binding protein also known as Ras-related proteins or simply RAP is a type of small GTPase, similar in structure to Ras.

These proteins share approximately 50% amino acid identity with the classical RAS proteins and have numerous structural features in common. The most striking difference between RAP proteins and RAS proteins resides in their 61st amino acid: glutamine in RAS is replaced by threonine in RAP proteins. RAP counteracts the mitogenic function of RAS because it can interact with RAS GAPs and RAF in a competitive manner.
