Description of the country: Turkey has been inhabited since the paleolithic age, including various ancient Anatolian civilizations, Aeolian, Dorian and Ionian Greeks, Thracians, Armenians, and Assyrians. After Alexander the Great's conquest, the area was Hellenized, a process which continued under the Roman Empire and its transition into the Byzantine Empire. The Seljuk Turks began migrating into the area in the 11th century, starting the process of Turkification, which was greatly accelerated by the Seljuk victory over the Byzantines at the Battle of Manzikert in 1071. The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243, upon which it disintegrated into several small Turkish beyliks.
Geography of the country: Turkey is divided into seven census regions: Marmara, Aegean, Black Sea, Central Anatolia, Eastern Anatolia, Southeastern Anatolia and the Mediterranean. The uneven north Anatolian terrain running along the Black Sea resembles a long, narrow belt. This region comprises approximately one-sixth of Turkey's total land area. As a general trend, the inland Anatolian plateau becomes increasingly rugged as it progresses eastward.
Status of economy, research and development: Turkey has a sizeable automotive industry, which produced over a million motor vehicles in 2012, ranking as the 17th largest producer in the world. Turkish shipbuilding exports were worth US$1.2 billion in 2011. The major export markets are Malta, Marshall Islands, Panama and the United Kingdom. Turkish shipyards have 15 floating docks of different sizes and one dry dock. Tuzla, Yalova, and ?zmit have developed into dynamic shipbuilding centres. In 2011, there were 70 active shipyards in Turkey, with another 56 being built. Turkish shipyards are highly regarded both for the production of chemical and oil tankers up to 10,000 dwt and also for their mega yachts.
Pulmonology Flock worker's lung is an occupational lung disease caused by exposure to flock, small fibers that are glued to a backing in order to create a specific texture. People who work in flocking are at risk of inhaling the small fibers, which causes interstitial lung disease. The disease was initially described in 1998, when a group of workers at a flocking plant developed interstitial lung disease of unknown etiology.
