paragraph_text: With the introduction of the blast furnace to Europe in the Middle Ages, pig iron was able to be produced in much higher volumes than wrought iron. Because pig iron could be melted, people began to develop processes of reducing the carbon in the liquid pig iron to create steel. Puddling was introduced during the 1700s, where molten pig iron was stirred while exposed to the air, to remove the carbon by oxidation. In 1858, Sir Henry Bessemer developed a process of steel-making by blowing hot air through liquid pig iron to reduce the carbon content. The Bessemer process was able to produce the first large scale manufacture of steel. Once the Bessemer process began to gain widespread use, other alloys of steel began to follow. Mangalloy, an alloy of steel and manganese exhibiting extreme hardness and toughness, was one of the first alloy steels, and was created by Robert Hadfield in 1882.

paragraph_text: An iceberg or ice mountain is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water. It may subsequently become frozen into pack ice (one form of sea ice). As it drifts into shallower waters, it may come into contact with the seabed, a process referred to as seabed gouging by ice. Also, about 91% of an iceberg is below the surface of the water.

paragraph_text: The Columbia Encyclopedia distinguishes between the Yuan dynasty and the other Mongol Empire khanates of Ilkhanate, Chagatai Khanate and the Golden Horde. It describes the Yuan dynasty as "A Mongol dynasty of China that ruled from 1271 to 1368, and a division of the great empire conquered by the Mongols. Founded by Kublai Khan, who adopted the Chinese dynastic name of Yüan in 1271." The Encyclopedia Americana describes the Yuan dynasty as "the line of Mongol rulers in China" and adds that the Mongols "proclaimed a Chinese-style Yüan dynasty at Khanbaliq (Beijing)." The Metropolitan Museum of Art writes that the Mongol rulers of the Yuan dynasty "adopted Chinese political and cultural models; ruling from their capitals in Dadu, they assumed the role of Chinese emperors," although Tibetologist Thomas Laird dismissed the Yuan dynasty as a non-Chinese polity and plays down its Chinese characteristics. The Metropolitan Museum of Art also noted that in spite of the gradual assimilation of Yuan monarchs, the Mongol rulers largely ignored the literati and imposed harsh policies discriminating against southern Chinese. In his Kublai Khan: His Life and Times, Rossabi explains that Kublai "created government institutions that either resembled or were the same as the traditional Chinese ones", and he "wished to signal to the Chinese that he intended to adopt the trappings and style of a Chinese ruler".

paragraph_text: The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety. Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, can protect against allergies and autoimmune diseases. The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans. One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not. In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.

paragraph_text: Increasing military and cultural contacts with the Muslim world, including the Norman conquest of Islamic Sicily in 1090, the Crusades, beginning 1096, and the Islamic presence in Spain, may have influenced Medieval Europe's adoption of the pointed arch, although this hypothesis remains controversial. Certainly, in those parts of the Western Mediterranean subject to Islamic control or influence, rich regional variants arose, fusing Romanesque and later Gothic traditions with Islamic decorative forms, as seen, for example, in Monreale and Cefalù Cathedrals, the Alcázar of Seville, and Teruel Cathedral.

paragraph_text: Sam Doonby (John Schneider) is a mysterious drifter who gets off a bus one afternoon in a small Texas town to change and improve the lives of all he comes in contact with. It is a story of greed and envy, played out against the backdrop of the classic country and blues music that is performed in Leroy’s Bar. The film has been described by the producers as "Crazy Heart"-meets-"It's A Wonderful Life", while Schneider described it as ""It's A Wonderful Life" without the Wonderful."

paragraph_text: He represented Puerto Rico in the luge event at the 1984 Winter Olympics in Sarajevo, and was the only Puerto Rican representative at the Games. He was also the country's flagbearer. Tucker was, at the time, a doctoral student at Wesleyan University in the United States. He was later described by "Sports Illustrated" as "overweight but quick-witted" and as "the press's favorite loser". He finished last in his event, and reportedly "got a lot more press in the States than Paul Hildgartner, the Italian who won the gold medal". He described himself as "the luger who dripped blood", and "Time" reported that he "shed alarming amounts of skin bouncing off the wall".

paragraph_text: Travel and tourism continue to be extremely important for Portugal, with visitor numbers forecast to increase significantly in the future.[citation needed] However, the increasing competition from Eastern European destinations continues to develop, with the presence of similar attractions that are often cheaper in countries such as Croatia. Consequently, it has been necessary for the country to focus upon its niche attractions, such as health, nature and rural tourism, to stay ahead of its competitors.

paragraph_text: Wang Chong (; 27 – c. 100 AD), courtesy name Zhongren (仲任), was a Chinese meteorologist, astronomer, and philosopher active during the Han Dynasty. He developed a rational, secular, naturalistic and mechanistic account of the world and of human beings and gave a materialistic explanation of the origin of the universe. His main work was the "Lunheng" (論衡, "Critical Essays"). This book contained many theories involving early sciences of astronomy and meteorology, and Wang Chong was even the first in Chinese history to mention the use of the square-pallet chain pump, which became common in irrigation and public works in China thereafter. Wang also accurately described the process of the water cycle.

paragraph_text: Han-era astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth. Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds.

paragraph_text: The second law of thermodynamics states that the entropy of an isolated system never decreases. Such systems spontaneously evolve towards thermodynamic equilibrium, the state with maximum entropy. Non-isolated systems may lose entropy, provided their environment's entropy increases by at least that amount so that the total entropy increases. Entropy is a function of the state of the system, so the change in entropy of a system is determined by its initial and final states. In the idealization that a process is reversible, the entropy does not change, while irreversible processes always increase the total entropy.

paragraph_text: The late Turrell V. Wylie, a former professor of the University of Washington, and Li Tieh-tseng argue that the reliability of the heavily censored History of Ming as a credible source on Sino-Tibetan relations is questionable, in the light of modern scholarship. Other historians also assert that these Ming titles were nominal and did not actually confer the authority that the earlier Yuan titles had. Van Praag writes that the "numerous economically motivated Tibetan missions to the Ming Court are referred to as 'tributary missions' in the Ming Shih." Van Praag writes that these "tributary missions" were simply prompted by China's need for horses from Tibet, since a viable horse market in Mongol lands was closed as a result of incessant conflict. Morris Rossabi also writes that "Tibet, which had extensive contacts with China during the Yuan, scarcely had diplomatic relations with the Ming."

paragraph_text: Kolmaš writes that, as the Mongol presence in Tibet increased, culminating in the conquest of Tibet by a Mongol leader in 1642, the Ming emperors "viewed with apparent unconcern these developments in Tibet." He adds that the Ming court's lack of concern for Tibet was one of the reasons why the Mongols pounced on the chance to reclaim their old vassal of Tibet and "fill once more the political vacuum in that country." On the mass Mongol conversion to Tibetan Buddhism under Altan Khan, Laird writes that "the Chinese watched these developments with interest, though few Chinese ever became devout Tibetan Buddhists."

paragraph_text: With the Yuan dynasty crumbling, competing rebel groups began fighting for control of the country and thus the right to establish a new dynasty. In 1363, Zhu Yuanzhang eliminated his archrival and leader of the rebel Han faction, Chen Youliang, in the Battle of Lake Poyang, arguably the largest naval battle in history. Known for its ambitious use of fire ships, Zhu's force of 200,000 Ming sailors were able to defeat a Han rebel force over triple their size, claimed to be 650,000 - strong. The victory destroyed the last opposing rebel faction, leaving Zhu Yuanzhang in uncontested control of the bountiful Yangtze River Valley and cementing his power in the south. After the dynastic head of the Red Turbans suspiciously died in 1367 while a guest of Zhu, there was no one left who was remotely capable of contesting his march to the throne, and he made his imperial ambitions known by sending an army toward the Yuan capital Dadu (present - day Beijing) in 1368. The last Yuan emperor fled north to the upper capital Shangdu, and Zhu declared the founding of the Ming dynasty after razing the Yuan palaces in Dadu to the ground; the city was renamed Beiping in the same year. Zhu Yuanzhang took Hongwu, or ``Vastly Martial '', as his era name.

paragraph_text: .lk (.ලංකා/.இலங்கை) is the Internet country code top-level domain (ccTLD) for Sri Lanka. Foreign companies who do not have a local presence can only reserve their top-level and corresponding open second-level domains (either through the LK Domain Registry or agents). In order to register and use a name they must have a contact address in Sri Lanka (which may be obtained through an agent or law firm).

paragraph_text: The first celluloid as a bulk material for forming objects was made in 1855 in Birmingham, England, by Alexander Parkes, who was never able to see his invention reach full fruition, after his firm went bankrupt due to scale - up costs. Parkes patented his discovery after realising a solid residue remained after evaporation of the solvent from photographic collodion.

paragraph_text: Together with the concept of an economic ``elasticity ''coefficient, Alfred Marshall is credited with defining PED (`` elasticity of demand'') in his book Principles of Economics, published in 1890. He described it thus: ``And we may say generally: -- the elasticity (or responsiveness) of demand in a market is great or small according as the amount demanded increases much or little for a given fall in price, and diminishes much or little for a given rise in price ''. He reasons this since`` the only universal law as to a person's desire for a commodity is that it diminishes... but this diminution may be slow or rapid. If it is slow... a small fall in price will cause a comparatively large increase in his purchases. But if it is rapid, a small fall in price will cause only a very small increase in his purchases. In the former case... the elasticity of his wants, we may say, is great. In the latter case... the elasticity of his demand is small.'' Mathematically, the Marshallian PED was based on a point - price definition, using differential calculus to calculate elasticities.

paragraph_text: Due to the 1973 spike in oil prices, the economy of Iran was flooded with foreign currency, which caused inflation. By 1974, the economy of Iran was experiencing double digit inflation, and despite many large projects to modernize the country, corruption was rampant and caused large amounts of waste. By 1975 and 1976, an economic recession led to increased unemployment, especially among millions of youth who had migrated to the cities of Iran looking for construction jobs during the boom years of the early 1970s. By the late 1970s, many of these people opposed the Shah's regime and began to organize and join the protests against it.

Question: Whose presence increased in the country with many contacts with the country of the person able to describe the process of evaporation during Yuan?
Answer: the Mongols
