Johann Gottfried Tulla
Johann Gottfried Tulla (20 March 1770, in Karlsruhe – 27 March 1828, in Paris) was a German engineer who accomplished the straightening of the Rhine, improving navigation and alleviating the effects of flooding. His measures gave the Upper Rhine a completely new appearance. The river was deepened and channelled between embankments which narrowed the channels to a width of ; new sections were dug to straighten out its meandering course, and numerous small islands were removed. The effect was to reduce the river's length between Basel and Worms from . However, the straightening of the Upper Rhine had increased the streaming speed and thus permanently raised the flood risk in the regions of the Middle and the Lower Rhine, partial floodplain restoration is still performed in a joint program of Germany and France. Career Tulla began his training in 1792 with Karl Christian von Langsdorf. From 1794 to 1796 he traveled across Central Europe and to Scandinavia, studying hydraulic proje ...

Ludwigshafen Stadtteilbrunnen Tulla
Ludwigshafen, officially Ludwigshafen am Rhein (; meaning " Ludwig's Port upon Rhine"), is a city in the German state of Rhineland-Palatinate, on the river Rhine, opposite Mannheim. With Mannheim, Heidelberg, and the surrounding region, it forms the Rhine Neckar Area. Known primarily as an industrial city, Ludwigshafen is home to BASF, the world's largest chemical producer, and other companies. Among its cultural facilities are the Staatsphilharmonie Rheinland-Pfalz. It is the birthplace and deathplace of the former German chancellor Helmut Kohl. In 2012, Ludwigshafen was classified as a global city with ' Sufficiency' status by the Globalization and World Cities Research Network (GaWC). History Early history In antiquity, Celtic and Germanic tribes settled in the Rhine Neckar area. During the 1st century B.C. the Romans conquered the region, and a Roman auxiliary fort was constructed near the present suburb of Rheingönheim. The Middle Ages saw the foundation of some of ...

Switzerland In The Napoleonic Era
During the French Revolutionary Wars, the revolutionary armies marched eastward, enveloping Switzerland in their battles against Austria. In 1798, Switzerland was completely overrun by the French and was renamed the Helvetic Republic. The Helvetic Republic encountered severe economic and political problems. In 1798 the country became a battlefield of the Revolutionary Wars, culminating in the Battles of Zürich in 1799. In 1803 Napoleon's Act of Mediation reestablished a Swiss Confederation that partially restored the sovereignty of the cantons, and the former tributary and allied territories of Aargau, Thurgau, Graubünden, St. Gallen, Vaud and Ticino became cantons with equal rights. The Congress of Vienna of 1815 fully re-established Swiss independence and the European powers agreed to permanently recognise Swiss neutrality. At this time, the territory of Switzerland was increased for the last time, by the new cantons of Valais, Neuchâtel and Geneva. The Restoration, th ...

Engineers From Karlsruhe
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional pr ...

1770 Births
Year 177 ( CLXXVII) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Commodus and Plautius (or, less frequently, year 930 ''Ab urbe condita''). The denomination 177 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Montmartre Cemetery
The Cemetery of Montmartre (french: link=no, Cimetière de Montmartre) is a cemetery in the 18th arrondissement of Paris, France, that dates to the early 19th century. Officially known as the Cimetière du Nord, it is the third largest necropolis in Paris, after the Père Lachaise Cemetery and the Montparnasse Cemetery. History In the mid-18th century, overcrowding in the cemeteries of Paris had created numerous problems, from impossibly high funeral costs to unsanitary living conditions in the surrounding neighborhoods. In the 1780s, the Cimetière des Innocents was officially closed and citizens were banned from burying corpses within the city limits of Paris. During the early 19th century, new cemeteries were constructed outside the precincts of the capital: Montmartre in the north, Père Lachaise Cemetery in the east, Passy Cemetery in the west and Montparnasse Cemetery in the south. The Montmartre Cemetery was opened on 1 January 1825. It was initially known as le Cimetière ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaria
Malaria is a mosquito-borne infectious disease that affects humans and other animals. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria. Malaria is caused by single-celled microorganisms of the ''Plasmodium'' group. It is spread exclusively through bites of infected ''Anopheles'' mosquitoes. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites travel to the liver where they mature and reproduce. Five species of ''Plasmodium'' can infect and be spread by h ...

River Engineering
River engineering is a discipline of civil engineering which studies human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit. People have intervened in the natural course and behaviour of rivers since before recorded history—to manage the water resources, to protect against flooding, or to make passage along or across rivers easier. Since the Yuan Dynasty and Ancient Roman times, rivers have been used as a source of hydropower. From the late 20th century, the practice of river engineering has responded to environmental concerns broader than immediate human benefit. Some river engineering projects have focused exclusively on the restoration or protection of natural characteristics and habitats. Hydromodification encompasses the systematic response to alterations to riverine and non-riverine water bodies such as coastal waters (estuaries and bays) and lakes. The U.S. Environmental Protection Agency (EPA) has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Linth
The Linth (pronounced "lint") is a Swiss river that rises near the village of Linthal in the mountains of the canton of Glarus, and eventually flows into the Obersee section of Lake Zurich. It is about in length. The water power of the Linth was a main factor in the creation of the textile industry of the canton Glarus, and is today used to drive the Linth–Limmern power stations in its upper reaches. The river and its upper valley forms the boundary between the mountain ranges of the Glarus Alps, to its east and south, and the Schwyzer Alps, to its west. Course of the river The river rises to the south-west of the village of Linthal, at the foot the Tödi mountain (elevation ). It collects the water from several glaciers, including the Clariden Glacier and the Biferten Glacier, as well as various tributary streams, including the ''Oberstafelbach'', the ''Bifertenbach'', the ''Sandbach'', the ''Walenbach'' and the ''Limmerenbach''. The last of these is dammed to create t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
