full_context: Document 1: Institute of technology: In addition, France's education system includes many institutes of technology, embedded within most French universities. They are referred-to as institut universitaire de technologie (IUT). Instituts universitaires de technologie provide undergraduate technology curricula. 'Polytech institutes', embedded as a part of eleven French universities provide both undergraduate and graduate engineering curricula.
Document 2: Black Death: Plague was reportedly first introduced to Europe via Genoese traders at the port city of Kaffa in the Crimea in 1347. After a protracted siege, during which the Mongol army under Jani Beg was suffering from the disease, the army catapulted the infected corpses over the city walls of Kaffa to infect the inhabitants. The Genoese traders fled, taking the plague by ship into Sicily and the south of Europe, whence it spread north. Whether or not this hypothesis is accurate, it is clear that several existing conditions such as war, famine, and weather contributed to the severity of the Black Death.
Document 3: Rhine: Until the early 1980s, industry was a major source of water pollution. Although many plants and factories can be found along the Rhine up into Switzerland, it is along the Lower Rhine that the bulk of them are concentrated, as the river passes the major cities of Cologne, Düsseldorf and Duisburg. Duisburg is the home of Europe's largest inland port and functions as a hub to the sea ports of Rotterdam, Antwerp and Amsterdam. The Ruhr, which joins the Rhine in Duisburg, is nowadays a clean river, thanks to a combination of stricter environmental controls, a transition from heavy industry to light industry and cleanup measures, such as the reforestation of Slag and brownfields. The Ruhr currently provides the region with drinking water. It contributes 70 m3/s (2,500 cu ft/s) to the Rhine. Other rivers in the Ruhr Area, above all, the Emscher, still carry a considerable degree of pollution.
Document 4: Science and technology in Wallonia: Science and technology in Wallonia, the southern region of Belgium (Europe), is well developed with the presence of several universities and research institutes.
Document 5: Jacques-Cartier River: Logging in the Laurentian highlands became an important economic activity during the second half of the 18th century. The Jacques-Cartier River was used for log drives to transport the logs to the Saint-Lawrence River and to the mills downstream. This practice was only stopped in 1975. With the settlement of French immigrants near the river's mouth came the formation of townships (modelled after English townships after their conquest of 1759) and new industries appeared such as flour mills.
Document 6: Black Death: The Black Death is thought to have originated in the dry plains of Central Asia, where it then travelled along the Silk Road, reaching Crimea by 1343. From there, it was most likely carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships, spreading throughout the Mediterranean and Europe.
Document 7: Devil's Backbone State Forest: Although much of future state forest was too steep and the soil too thin for agriculture, it nonetheless was part of a growing Virginia economy. The first industry to use the forest was iron furnaces established in the mid-18th century and existing until after the Civil War. Isaac Zane, a Quaker from Pennsylvania, built the first two of these furnaces (Zane's Old Furnace 1768-74 and The Marlboro Works 1772-95) and received grants of forest land which included the future state forest to be used to make charcoal as fuel.
Document 8: Belgium: Belgium was the first continental European country to undergo the Industrial Revolution, in the early 19th century. Liège and Charleroi rapidly developed mining and steelmaking, which flourished until the mid-20th century in the Sambre and Meuse valley and made Belgium among one of the three most industrialized nations in the world from 1830 to 1910. However, by the 1840s the textile industry of Flanders was in severe crisis, and the region experienced famine from 1846 to 1850.After World War II, Ghent and Antwerp experienced a rapid expansion of the chemical and petroleum industries. The 1973 and 1979 oil crises sent the economy into a recession; it was particularly prolonged in Wallonia, where the steel industry had become less competitive and experienced serious decline. In the 1980s and 1990s, the economic center of the country continued to shift northwards and is now concentrated in the populous Flemish Diamond area.By the end of the 1980s, Belgian macroeconomic policies had resulted in a cumulative government debt of about 120% of GDP. As of 2006, the budget was balanced and public debt was equal to 90.30% of GDP. In 2005 and 2006, real GDP growth rates of 1.5% and 3.0%, respectively, were slightly above the average for the Euro area. Unemployment rates of 8.4% in 2005 and 8.2% in 2006 were close to the area average. By October 2010, this had grown to 8.5% compared to an average rate of 9.6% for the European Union as a whole (EU 27). From 1832 until 2002, Belgium's currency was the Belgian franc. Belgium switched to the euro in 2002, with the first sets of euro coins being minted in 1999. The standard Belgian euro coins designated for circulation show the portrait of the monarch (first King Albert II, since 2013 King Philippe).
Document 9: Black Death: The Black Death is thought to have originated in the dry plains of Central Asia, where it then travelled along the Silk Road, reaching Crimea by 1343. From there, it was most likely carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships. Spreading throughout the Mediterranean and Europe.
Document 10: Black Death: The Black Death is thought to have originated in the arid plains of Central Asia, where it then travelled along the Silk Road, reaching Crimea by 1343. From there, it was most likely carried by Oriental rat fleas living on the black rats that were regular passengers on merchant ships. Spreading throughout the Mediterranean and Europe, the Black Death is estimated to have killed 30 -- 60% of Europe's total population. In total, the plague may have reduced the world population from an estimated 450 million down to 350 -- 375 million in the 14th century. The world population as a whole did not recover to pre-plague levels until the 17th century. The plague recurred occasionally in Europe until the 19th century.
Document 11: Black Death: The disease may have travelled along the Silk Road with Mongol armies and traders or it could have come via ship. By the end of 1346, reports of plague had reached the seaports of Europe: ``India was depopulated, Tartary, Mesopotamia, Syria, Armenia were covered with dead bodies ''.
Document 12: Southern California: The Tech Coast is a moniker that has gained use as a descriptor for the region's diversified technology and industrial base as well as its multitude of prestigious and world-renowned research universities and other public and private institutions. Amongst these include 5 University of California campuses (Irvine, Los Angeles, Riverside, Santa Barbara, and San Diego); 12 California State University campuses (Bakersfield, Channel Islands, Dominguez Hills, Fullerton, Los Angeles, Long Beach, Northridge, Pomona, San Bernardino, San Diego, San Marcos, and San Luis Obispo); and private institutions such as the California Institute of Technology, Chapman University, the Claremont Colleges (Claremont McKenna College, Harvey Mudd College, Pitzer College, Pomona College, and Scripps College), Loma Linda University, Loyola Marymount University, Occidental College, Pepperdine University, University of Redlands, University of San Diego, and the University of Southern California.
Document 13: Institute of technology: Hogeschool is used in Belgium and in the Netherlands. The hogeschool has many similarities to the Fachhochschule in the German language areas and to the ammattikorkeakoulu in Finland.
Document 14: Belgium: Belgium, officially the Kingdom of Belgium, is a country in Western Europe bordered by France, the Netherlands, Germany and Luxembourg. A small and densely populated country, it covers an area of 30,528 square kilometres (11,787 sq mi) and has a population of more than 11 million. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch - speaking, mostly Flemish community, which constitutes about 59 percent of the population, and the French - speaking, mostly Walloon population, which comprises about 40 percent of all Belgians. Additionally, there is a small group of German speakers, numbering around one percent, who live in the East Cantons. The capital and largest city is Brussels; other major cities are Antwerp, Ghent, Charleroi and Liège.
Document 15: Ardennes: The trees and rivers of the Ardennes provided the charcoal industry assets that enabled the great industrial period of Wallonia in the 18th and 19th centuries, when it was arguably the second great industrial region of the world, after England. The greater region maintained an industrial eminence into the 20th century, after coal replaced charcoal in metallurgy.
